Using protocols in ICU practice. Engaging the staff.

Aims/Purpose: Protocols are evidenced-based structured guides for directing care to achieve improvements. But translating that evidence into practice is a major challenge. It is not acceptable to simply introduce the protocol and expect it to be adopted and lead to change in practice. Implementation requires effective leadership and management. This presentation describes a strategy for implementation that should promote successful adoption and lead to practice change.
Presentation description: There are many social and behavioural change models to assist and guide practice change. Choosing a model to guide implementation is important for providing a framework for action. The change process requires careful thought, from the protocol itself to the policies and politics within the ICU. In this presentation, I discuss a useful pragmatic guide called the 6SQUID (6 Steps in QUality Intervention Development). This was initially designed for public health interventions, but the model has wider applicability and has similarities with other change process models. Steps requiring consideration include examining the purpose and the need for change; the staff that will be affected and the impact on their workload; and the evidence base supporting the protocol. Subsequent steps in the process that the ICU manager should consider are the change mechanism (widespread multi-disciplinary consultation; adapting the protocol to the local ICU); and identifying how to deliver the change mechanism (educational workshops and preparing staff for the changes are imperative). Recognising the barriers to implementation and change and addressing these locally is also important. Once the protocol has been implemented, there is generally a learning curve before it becomes embedded in practice. Audit and feedback on adherence are useful strategies to monitor and sustain the changes.
Conclusion: Managing change successfully will promote a positive experience for staff. In turn, this will encourage a culture of enthusiasm for translating evidence into practice.

Home and group-based implementation of the "Growing Up Happily in the Family" program in at-risk psychosocial contexts

"Growing Up Happily in the Family" is a program to prevent child maltreatment targeted at parents of children aged 0-5 years old in at-risk psychosocial contexts. The program is delivered via either a group-based or a home-visit format. The objective of this study was to evaluate the impact of various implementation components in the home and group versions on changes in parental attitudes about child development and education. At-risk and non at-risk parents participated in the group-based (196 participants in 26 groups) and home-visit (95 participants) versions of the program delivered through local social services. We analyzed program adherence, adaptations, participant responsiveness, quality of delivery, and implementation barriers as predictors of changes in parental attitudes. The results showed that greater program adherence, better quality of delivery and participant responsiveness, and positive climate predicted changes in parental attitudes in both formats. Therefore, it is important to take into account the quality of the implementation process when testing the effectiveness of early group-based and home-visit interventions in at-risk families.

Pressure Ulcer Knowledge Among Nurses in a Brazilian University Hospital

To facilitate the implementation of evidence-based skin and pressure ulcer (PU) care practices and related staff education programs in a university hospital in Brazil, a cross-sectional study was conducted to evaluate nurses` knowledge about PU prevention, wound assessment, and staging. Of the 141 baccalaureate nurses (BSN) employed by the hospital at the time of the study, 106 consented to participate. Using a Portuguese version of Pieper`s Pressure Ulcer Knowledge Test (PUKT), participants were asked to indicate whether 33 statements about PU prevention and eight about PU assessment and staging were true or false. For the 33 prevention statements, the average number answered correctly was 26.07 (SD 4.93) and for the eight assessment statements the average was 4.59 (SD 1.62). Nurses working on inpatient clinical nursing units had significantly better scores (P = 0.000). Years of nursing experience had a weak and negative correlation with correct PUKT scores (r = -0.21, P = 0.033) as did years of experience working in the university hospital (r = -.179, P <071). Incorrect responses were most common for statements related to patient positioning, massage, PU assessment, and staging definitions. The results of this study confirm that nurses have an overall understanding of PU prevention and assessment principles but important knowledge deficits exist. Focused continuing education efforts are needed to facilitate the implementation of evidence-based care.

Mental health nursing standards and practice indicators for Australia: a review of current literature

There are many changes and challenges facing the mental health care professional working in Australia in the 21st Century. Given the significance of their number and the considerable extent to which care is delivered by them, mental health nurses in particular must be at the forefront of the movement to enhance and improve mental health care. Mental health nurses in Australia must not only keep up with the changes, we should be setting the pace for others across the profession worldwide. The increasingly complex field of mental health nursing demands nurses who are not only equipped to face the challenges but are confident in doing so. Definitive guidelines for practice, clear expectations regarding outcomes and specific means by which to evaluate both practice and outcomes are vital. Strengthening the role and vision of mental health nursing so that there is clarity about both and highlighting core values by which to perform will enable us to become focused on our future and what we can expect to both give to and receive from our chosen profession and how we can, and do, contribute to mental health care. The role of the mental health nurse is undergoing expansion and there are new hurdles to overcome along with the new benefits this brings. To support this, nationally adopted, formalised standards of practice and means by which to measure these, i.e., practice indicators formerly known as clinical indicators, are required. It is important to have national standards and practice indicators because of the variances in the provision of mental health across Australia – different legislation regarding mental health policies and processes, different nursing registration bodies and Nursing Councils, for example – which create additional barriers to cohesion and uniformity. Improvements in the practice of mental health nursing lead to benefits for consumer outcomes as well as the overall quality of mental health care available in Australia. The emphasis on rights-based care, particularly consumer and carer rights, demands evidence-based, up-to-date mental health care delivered by competent, capable professionals. Documented expectations for performance by nurses will provide all involved with yardsticks by which to evaluate outcomes. Flowing on from these benefits are advances in mental health care generally and enhancements to Australia’s reputation and position within the health care arena throughout the world. Currently, the ‘Standards for Practice’ published by the Australian New Zealand College of Mental Health Nurses (ANZCMHN) in 1995 and the practice indicators developed by Skews et al. (2000) provide a less formal guide for mental health nurses working in Australia. While these earlier standards and practice indicators have played some role in supporting mental health nurses they have not been nationally or enthusiastically adopted and there are a multitude of reasons for this. This report reviews the current literature available on practice indicators and standards for practice and describes an evidence-based rationale as to why a review and renewal of these is required and why it is important, not just for mental health nurses but to the field of mental health in general. The term ‘practice indicator’ is used, except where a quotation utilises ‘clinical indicator’, to more accurately reflect the broad spectrum of nursing roles, i.e. not all mental health nursing work involves a clinical role.

Royal Australian and New Zealand College of Psychiatrists clinical practice guidelines for the treatment of schizophrenia and related disorders

Background: The Royal Australian and New Zealand College of Psychiatrists is co-ordinating the development of clinical practice guidelines (CPGs) in psychiatry, funded under the National Mental Health Strategy (Australia) and the New Zealand Health Funding Authority. This paper presents CPGs for schizophrenia and related disorders. Over the past decade schizophrenia has become more treatable than ever before. A new generation of drug therapies, a renaissance of psychological and psychosocial interventions and a first generation of reform within the specialist mental health system have combined to create an evidence-based climate of realistic optimism. Progressive neuroscientific advances hold out the strong possibility of more definitive biological treatments in the near future. However, this improved potential for better outcomes and quality of life for people with schizophrenia has not been translated into reality in Australia. The efficacy-effectiveness gap is wider for schizophrenia than any other serious medical disorder. Therapeutic nihilism, under-resourcing of services and a stalling of the service reform process, poor morale within specialist mental health services, a lack of broad-based recovery and life support programs, and a climate of tenacious stigma and consequent lack of concern for people with schizophrenia are the contributory causes for this failure to effectively treat. These guidelines therefore tackle only one element in the endeavour to reduce the impact of schizophrenia. They distil the current evidence-base and make recommendations based on the best available knowledge. Method: A comprehensive literature review (1990-2003) was conducted, including all Cochrane schizophrenia reviews and all relevant meta-analyses, and a number of recent international clinical practice guidelines were consulted. A series of drafts were refined by the expert committee and enhanced through a bi-national consultation process. Treatment recommendations: This guideline provides evidence-based recommendations for the management of schizophrenia by treatment type and by phase of illness. The essential features of the guidelines are: (i) Early detection and comprehensive treatment of first episode cases is a priority since the psychosocial and possibly the biological impact of illness can be minimized and outcome improved. An optimistic attitude on the part of health professionals is an essential ingredient from the outset and across all phases of illness. (ii) Comprehensive and sustained intervention should be assured during the initial 3-5 years following diagnosis since course of illness is strongly influenced by what occurs in this 'critical period'. Patients should not have to 'prove chronicity' before they gain consistent access and tenure to specialist mental health services. (iii) Antipsychotic medication is the cornerstone of treatment. These medicines have improved in quality and tolerability, yet should be used cautiously and in a more targeted manner than in the past. The treatment of choice for most patients is now the novel antipsychotic medications because of their superior tolerability and, in particular, the reduced risk of tardive dyskinesia. This is particularly so for the first episode patient where, due to superior tolerability, novel agents are the first, second and third line choice. These novel agents are nevertheless associated with potentially serious medium to long-term side-effects of their own for which patients must be carefully monitored. Conventional antipsychotic medications in low dosage may still have a role in a small proportion of patients, where there has been full remission and good tolerability; however, the indications are shrinking progressively. These principles are now accepted in most developed countries. (vi) Clozapine should be used early in the course, as soon as treatment resistance to at least two antipsychotics has been demonstrated. This usually means incomplete remission of positive symptomatology, but clozapine may also be considered where there are pervasive negative symptoms or significant or persistent suicidal risk is present. (v) Comprehensive psychosocial interventions should be routinely available to all patients and their families, and provided by appropriately trained mental health professionals with time to devote to the task. This includes family interventions, cognitive-behaviour therapy, vocational rehabilitation and other forms of therapy, especially for comorbid conditions, such as substance abuse, depression and anxiety. (vi) The social and cultural environment of people with schizophrenia is an essential arena for intervention. Adequate shelter, financial security, access to meaningful social roles and availability of social support are essential components of recovery and quality of life. (vii) Interventions should be carefully tailored to phase and stage of illness, and to gender and cultural background. (viii) Genuine involvement of consumers and relatives in service development and provision should be standard. (ix) Maintenance of good physical health and prevention and early treatment of serious medical illness has been seriously neglected in the management of schizophrenia, and results in premature death and widespread morbidity. Quality of medical care for people with schizophrenia should be equivalent to the general community standard. (x) General practitioners (GPs)s should always be closely involved in the care of people with schizophrenia. However, this should be truly shared care, and sole care by a GP with minimal or no special Optimal treatment of schizophrenia requires a multidisciplinary team approach with a consultant psychiatrist centrally involved.

Insuficiência cardíaca. Uma epidemia do século XXI. O desafio do diagnóstico

Resumo: A insuficiência cardíaca, já denominada de epidemia do século XXI é, de entre as doenças cardiovasculares, a única cuja incidência e prevalência continuam a crescer, apesar dos imensos progressos feitos na área da terapêutica nas últimas duas décadas. Caracteriza-se por elevada mortalidade – superior à do conjunto das neoplasias malignas -, grande morbilidade, consumo de recursos e custos exuberantes. É um dos problemas mais graves de Saúde Pública dos Países industrializados, cujo manejo deverá constituir uma prioridade para os Serviços Nacionais de Saúde. Todavia, o reconhecimento universal da gravidade desta situação tem originado poucas soluções concretas para conter a epidemia, cujo protagonismo não cessa de aumentar. É possível hoje prevenir, tratar de forma a retardar a evolução da doença ou até revertê-la, desde que diagnosticada atempadamente. Qualquer atitude nestas áreas pressupõe um diagnóstico correcto, precoce e completo da situação, sem o qual não haverá um tratamento adequado. O diagnóstico tem preocupado bem menos os investigadores e os clínicos que a terapêutica. É, contudo, comprovadamente difícil a todos os níveis dos Cuidados de Saúde e constitui certamente a primeira barreira ao controlo da situação. OBJECTIVOS: À luz do conhecimento actual e da nossa própria experiência, propusemo-nos analisar os problemas do diagnóstico da insuficiência cardíaca e a forma como eles se repercutem no manejo da doença e na saúde das populações. Foram objectivos desta dissertação avaliar como a evolução dos modelos de insuficiência cardíaca e de disfunção ventricular influenciaram a definição e os critérios de diagnóstico da doença ao longo do tempo; as consequências geradas pela falta de consenso quanto à definição e aos critérios de diagnóstico nas diferentes fases de evolução desta entidade; discutir o papel da clínica e dos exames complementares no diagnóstico da síndrome e nas estratégias de rastreio da disfunção cardíaca; apontar alguns caminhos e possíveis metodologias para o manejo da doença de forma a que possamos, no futuro, diagnosticar melhor para melhor prevenir, tratar e conter a epidemia. METODOLOGIA: A metodologia utilizada neste trabalho decorre directamente da actividade assistencial diária e da investigação clínica gerada no interesse pelos problemas com que nos deparámos, ao longo dos anos, na área da insuficiência cardíaca. A par com o estudo epidemiológico da insuficiência cardíaca em Portugal, desenvolvemos um protocolo original para a avaliação da qualidade do diagnóstico no ambulatório e do papel da clínica e dos diferentes exames complementares no diagnóstico da síndrome. Avaliámos os problemas do diagnóstico da insuficiência cardíaca em meio hospitalar através de um inquérito endereçado aos Directores de Serviço, pelo Grupo de Estudo de Insuficiência Cardíaca da Sociedade Portuguesa de Cardiologia. Analisámos a qualidade do diagnóstico da insuficiência cardíaca codificado à data da alta hospitalar. Após a criação de uma área específica, vocacionada para o internamento de doentes com insuficiência cardíaca, avaliámos o seu impacto no diagnóstico e tratamento da síndrome. Também testámos o desempenho dos peptídeos natriuréticos no diagnóstico dos diferentes tipos de insuficiência cardíaca sintomática, em meio hospitalar. Os resultados parciais da investigação clínica foram sendo comunicados à comunidade científica e publicados em revistas da especialidade. Discutimos, nesta dissertação, os artigos publicados e em publicação, à luz do estado actual da arte na área do diagnóstico. Reflectimos sobre as consequências das dificuldades no diagnóstico da insuficiência cardíaca e apontamos possíveis caminhos para implementar o rastreio. RESULTADOS: Em 1982, muito no início da nossa actividade clínica, cientes da complexidade da insuficiência cardíaca e do desafio que a sua abordagem constituía para os clínicos,empenhávamo-nos no desenvolvimento de uma classificação fisiopatológica original da insuficiência cardíaca, que foi tema para a Tese de Doutoramento da Professora Doutora Fátima Ceia em 1989. sistemático da doença, melhorar os cuidados prestados aos doentes e diminuir os custos envolvidos no manejo da síndrome. No artigo 1 – Insuficiência cardíaca: novos conceitos fisiopatológicos e implicações terapêuticas – publicado em 1984, descrevemos, à luz do conhecimento da época, a insuficiência cardíaca como uma doença sistémica, resultado da interacção entre os múltiplos mecanismos de compensação da disfunção cardíaca. Desenvolvemos “uma classificação fisiopatológica com implicações terapêuticas” original, onde delineámos os diferentes tipos de insuficiência cardíaca, as suas principais características clínicas, hemodinâmicas, funcionais e anatómicas e propuzemos terapêutica individualizada de acordo com a definição e o diagnóstico dos diferentes tipos de insuficiência cardíaca. Em 1994, no artigo 2 – A insuficiência cardíaca e o clínico no fim do século vinte – salientamos a forma como os diferentes mecanismos de compensação interagem, influenciam a evolução da doença no tempo, produzem síndromes diferentes e fundamentam a actuação terapêutica. Discutimos a evolução da definição da doença de acordo com o melhor conhecimento da sua fisiopatologia e etiopatogenia. Sublinhamos a necessidade de desenvolver estratégias para a prevenção da doença, o diagnóstico precoce e o tratamento atempado. Ainda no primeiro capítulo: Insuficiência cardíaca: da fisiopatologia à clínica – um modelo em constante evolução – revisitámos os sucessivos modelos fisiopatológicos da insuficiência cardíaca: cardio-renal, hemodinâmico, neuro-hormonal e imuno-inflamatório e a sua influência na definição da síndrome e nos critérios de diagnóstico. Analisámos a evolução do conceito de disfunção cardíaca que, à dicotomia da síndrome em insuficiência cardíaca por disfunção sistólica e com função sistólica normal, contrapõe a teoria do contínuo na evolução da doença. Esta última, mais recente, defende que estas duas formas de apresentação não são mais do que fenótipos diferentes, extremos, de uma mesma doença que origina vários cenários, desde a insuficiência cardíaca com fracção de ejecção normal à disfunção sistólica ventricular grave No capítulo II - O diagnóstico da insuficiência cardíaca: problemas e consequências previsíveis - analisamos as consequências da falta de critérios de diagnóstico consensuais para a insuficiência cardíaca em todo o seu espectro, ao longo do tempo. As dificuldades de diagnóstico reflectem-se nos resultados resultados dos estudos epidemiológicos. Vivemos essa dificuldade quando necessitámos de definir critérios de diagnóstico exequíveis no ambulatório, abrangendo todos os tipos de insuficiência cardíaca e de acordo com as Recomendações, para o programa EPICA –EPidemiologia da Insuficiência Cardíaca e Aprendizagem – desenhado para os Cuidados Primários de Saúde. No artigo 3 – Epidemiologia da insuficiência cardíaca e Aprendizagem – desenhado para os Cuidados Primários de Saúde. No artigo 3 – Epidemiologia da insuficiência cardíaca – discutimos as consequências dos grandes estudos epidemiológicos terem adoptado ao longo dos anos definições e critérios de diagnóstico muito variáveis,conduzindo a valores de prevalência e incidência da doença por vezes também muito diferentes. O problema agudiza-se quando se fala em insuficiência cardíaca com fracção de ejecção normal ou com disfunção diastólica, ou ainda em rastreio da disfunção cardíaca assintomática, situações para as quais tem sido extraordinariamente difícil consensualizar critérios de diagnóstico e estratégias. É notória a ausência de grandes estudos de terapêutica no contexto da insuficiência cardíaca com fracção de ejecção normal ou com disfunção diastólica que, à falta de Recomendações terapêuticas baseadas na evidência, continuamos a tratar de acordo com a fisiopatologia. Assim, discrepâncias provavelmente mais relacionadas com os critérios de diagnóstico utilizados do que com diferenças reais entre as populações, dificultam o nosso entendimento quanto ao real peso da insuficiência cardíaca e da disfunção ventricular assintomática. Também comprometerão certamente a correcta alocação de recursos para necessidades que, na realidade, conhecemos mal. O artigo 4 – Prévalence de l’ insuffisance cardiaque au Portugal – apresenta o desenho dos estudos EPICA e EPICA-RAM. O EPICA foi dos primeiros estudos a avaliar a prevalência da insuficiência cardíaca sintomática global, na comunidade, de acordo com os critérios da Sociedade Europeia de Cardiologia. Definimos critérios ecocardiográficos de disfunção cardíaca para todos os tipos de insuficiência cardíaca, nomeadamente para as situações com fracção de ejecção normal, numa época em que ainda não havia na literatura Recomendações consensuais. No artigo 5 – Prevalence of chronic heart failure in Southwestern Europe: the EPICA study - relatamos a prevalência da insuficiência cardíaca em Portugal con-supra-diagnosticada em 8,3%. A codificação hospitalar falhou uma percentagem significativa de doentes com insuficiência cardíaca, minimizando assim o peso da síndrome, com eventual repercussão na alocação dos recursos necessários ao seu manejo no hospital e para a indispensável interface com os Cuidados Primários de Saúde. No artigo 8 – Tratamento da insuficiência cardíaca em hospitais portugueses: resultados de um inquérito – todos os inquiridos relataram dificuldades no diagnóstico atempado da insuficiência cardíaca. Os Directores dos Serviços de Cardiologia reclamam mais recursos humanos vocacionados e estruturas hospitalares especializadas no diagnóstico e tratamento da síndrome, enquanto que os Directores dos Serviços de Medicina necessitam de facilidades de acesso aos métodos complementares de diagnóstico como a ecocardiografia e de maior apoio do Cardiologista. As dificuldades no diagnóstico da insuficiência cardíaca,a todos os níveis de cuidados, acarretam assim consequências epidemiológicas, sócio-económicas e financeiras nefastas para o doente individual, a planificação do Sistema Nacional de Saúde e para a Saúde Pública No capítulo III relembramos a importância do diagnóstico completo da insuficiência cardíaca que, para além do diagnóstico sindromático e anatomo-funcional, deverá incluir o diagnóstico etiológico, e das comorbilidades. Muitos destes aspectos podem comprometer a interpretação dos exames complementares de diagnóstico e, não raramente, as indicações dos fármacos que influenciam a sobrevida dos doentes, a estratégia terapêutica e o prognóstico da síndrome Conscientes das dificuldades no diagnóstico da insuficiência cardíaca nos Cuidados Primários de Saúde e do papel preponderante dos especialistas em Medicina Familiar na contenção da epidemia, propusemo-nos, como objectivos secundários do estudo EPICA (artigo 5), investigar a acuidade diagnóstica dos instrumentos à disposição daqueles colegas, na prática clínica diária: a clínica e os exames complementares de diagnóstico de primeira linha. O artigo 10 – The diagnosis of heart failure in primary care: value of symptoms and signs - documenta o valor limitado dos sinais, sintomas e dados da história pregressa, quando usados isoladamente, no diagnóstico da síndrome. Todos têm baixa sensibilidade para o diagnóstico. Têm maior valor preditor os associados às situações congestivas, mais graves: a dispneia paroxística nocturna (LR 35,5), a ortopneia (LR 39,1), a dificuldade respiratória para a marcha em plano horizontal (LR 25,8), o ingurgitamento jugular > 6 cm com hepatomegalia e edema dos membros inferiores (LR 130,3), que estão raramente presentes na população de insuficientes cardíacos do ambulatório (sensibilidade <10%). O galope ventricular (LR 30,0), a taquicardia >110ppm (LR 26,7) e os fervores crepitantes (LR 23,3) também estão associados ao diagnóstico, mas são também pouco frequentes na população estudada (sensibilidade < 36%). São ainda preditores do diagnóstico o tratamento prévio com digitálico (LR 24,9) e/ou com diurético (LR 10,6), uma história prévia de edema pulmonar agudo (LR 54,2) ou de doença das artérias coronárias (LR 7,1). No artigo 11- Aetiology, comorbidity and drug therapy of chronic heart failure in the real world: the EPICA substudy - confirmámos que a hipertensão arterial é, de entre os factores de risco e/ou etiológicos, a causa mais frequente de insuficiência cardíaca no ambulatório, em Portugal (80%). Trinta e nove por cento dos doentes do estudo EPICA têm história de doença coronária e 15% de fibrilhação auricular. Quantificámos a comorbilidade e analisámos a sua potencial influência no facto da prescrição terapêutica estar aquém das Recomendações internacionais em Portugal, como aliás em toda a Europa. No artigo 12 - The value of electrocardiogram and X-ray for confirming or refuting a suspected diagnosis of heart failure in the community – demonstrámos que os dados do ECG e do RX do tórax não permitem predizer o diagnóstico de insuficiência cardíaca na comunidade; 25% dos doentes com insuficiência cardíaca objectiva tinham ECG ou RX do tórax normais. No artigo 13 - Evaluation of the performance and concordance of clinical questionnaires for heart failure in primary care - comparámos sete questionários e sistemas de pontuação habitualmente utilizados nos grandes estudos, para o diagnóstico da insuficiência cardíaca. Mostraram ter, na sua maioria, uma concordância razoável ou boa entre si. Foram muito específicos (>90%) mas pouco sensíveis. Aumentaram a probabilidade do diagnóstico de 4,3% pré-teste para 25 a 30% pós-teste. Revelaram-se um melhor instrumento para a exclusão da causa cardíaca dos sintomas do que para o diagnóstico da síndrome O artigo 14 - Epidemiologia da insuficiência cardíaca em Portugal continental: novos dados do estudo EPICA – compara as características dos doentes com suspeita clínica, não comprovada, de insuficiência cardíaca (falsos positivos), com os casos de insuficiência cardíaca. Os primeiros são mais idosos, mais mulheres, com mais excesso de peso, menos história de doença das artérias coronárias. Confirma ainda que a clínica, o ECG e o Rx tórax não permitem diferenciar os doentes com insuficiência cardíaca por disfunção sistólica ventricular daqueles que têm fracção de ejecção normal. Perante o desafio do diagnóstico da insuficiência cardíaca com fracção de ejecção normal, as dificuldades de acesso à ecocardiografia na comunidade e os custos acrescidos do exame, pretendemos averiguar no artigo 15 - The diagnostic challenge of heart failure with preserved systolic function in primary care setting: an EPICA-RAM sub-study - o desempenho do BNP no rastreio dos doentes com a suspeita clínica do diagnóstico, a enviar para ecocardiografia. Testámos o desempenho do teste como preditor do diagnóstico clínico da insuficiência cardíaca com função sistólica preservada, bem como dos indicadores ecocardiográficos de disfunção diastólica utilizados no estudo: dilatação da aurícula esquerda e hipertrofia ventricular esquerda. O teste apenas foi bom preditor da dilatação da aurícula esquerda, mas não do diagnóstico clínico deste tipo de insuficiência cardíaca, nem da presença de hipertrofia ventricular esquerda diagnosticada por ecocardiografia (área abaixo da curva ROC: 0,89, 0,56 e 0,54 respectivamente). Concluímos que, isoladamente, não será um bom método de rastreio da doença na comunidade, nem poderá substituir o ecocardiograma no doente com a suspeita clínica do diagnóstico, pelo menos nas fases precoces, pouco sintomáticas da doença. Estudámos e comparámos o desempenho dos peptídeos natriuréticos do tipo B - BNP e NT-proBNP - no diagnóstico da insuficiência cardíaca sintomática, por disfunção sistólica e com fracção de ejecção preservada, no internamento hospitalar. Avaliámos doentes e voluntários normais, de forma a estabelecermos os cut-off do nosso laboratório. Relatámos os resultados deste trabalho no artigo 16 – Valor comparativo do BNP e do NT-proBNP no diagnóstico da insuficiência cardía-ca. Ambos os testes tiveram um excelente desempenho no diagnóstico da insuficiência cardíaca sintomática, em meio hospitalar, mas nenhum foi capaz de diferenciar a insuficiência cardíaca com disfunção sistólica ventricular da que tem fracção de ejecção normal Revimos, à luz do conhecimento actual, o desempenho dos diferentes exames complementares, nomeadamente dos peptídeos natriuréticos e da ecocardiografia, no diagnóstico da insuficiência cardíaca sintomática global, por disfunção sistólica ventricular e com fracção de ejecção normal e discutimos os critérios mais recentemente propostos e as últimas Recomendações internacionais Discutimos as estratégias propostas para o rastreio da disfunção ventricular assintomática que é, na comunidade, pelo menos tão frequente quanto a sintomática. Existe evidência de que tratar precocemente a disfunção ventricular sistólica assintomática se traduz em benefícios reais no prognóstico e, tal como no caso da disfunção sistólica sintomática, é custo-eficiente. Autilização do método padrão para o rastreio da disfunção cardíaca na população obrigaria à realização de ecocardiograma a todos os indivíduos, o que é técnica e economicamente incomportável. Vários estudos têm vindo a testar diversas estratégias alternativas, na procura de uma metodologia que seja, também ela, custo-eficiente. Os autores são unânimes no aspecto em que nenhum exame, quando avaliado isoladamente, foi útil para o rastreio da disfunção cardíaca. Contudo apontam para o ECG e/ou os peptídeos natriuréticos, integrados ou não em esquemas de pontuação clínica, como testes úteis para o pré-rastreio para ecocardiografia. Permitem diminuir os pedidos de ecocardiograma e os custos do rastreio, que se torna tão custo-efectivo quanto o do cancro da mama ou do colo do útero. Alguns autores preconizam ainda a avaliação qualitativa da disfunção cardíaca por ecocardiograma portátil, no contexto de ECG anómalo ou de peptídeo natriurético elevado, antes da referenciação para o ecocardiograma completo. Apontam esta estratégia como sendo a mais custo-eficiente para o rastreio da disfunção cardíaca. Finalmente, tecemos alguns comentários finais quanto a perspectivas de futuro para o manejo da insuficiência cardíaca. É premente estabelecer uma definição precisa e universal da síndrome e critérios de diagnóstico consensuais, claros, objectivos, simples e reprodutíveis para todo o espectro da insuficiência cardíaca, para que possamos num futuro próximo avaliar de forma correcta a extensão do problema, organizar cuidados médicos eficientes e acessíveis a todos e melhorar o prognóstico dos doentes, numa política imprescindível e inevitável de contenção dos custos. Perante os problemas de diagnóstico da síndrome no ambulatório, consideramos ser necessário implementar programas de formação continuada e facilitar o diálogo e a colaboração entre Cuidados Primários de Saúde e Unidades especializadas no manejo da doença, à imagem do que fizemos pontualmente aquando do programa EPICA e do que está a ser desenvolvido em vários países europeus e nos Estados Unidos da América, sob a forma de redes alargada de prestação de cuidados, para a insuficiência cardíaca. As clínicas de insuficiência cardíaca, a laborar sobretudo em meio hospitalar, já deram provas quanto à maior conformidade do diagnóstico (e tratamento) de acordo com as Recomendações, assim como na melhoria da qualidade de vida e sobrevida dos doentes. No artigo 17 - Implementar as Recomendações na prática clínica: benefícios de uma Unidade de Insuficiência Cardíaca Aguda - relatamos a nossa experiência quanto à melhoria da qualidade dos cuidados prestados, nas áreas do diagnóstico e tratamento, numa unidade funcional dedicada ao internamento dos doentes com insuficiência cardíaca aguda. Defendemos que estas áreas específicas de internamento se devem articular com outras,nomeadamente hospitais de dia de insuficiência cardíaca, podendo ou devendo até ser diferentes na sua estrutura e recursos, de acordo com as necessidades das populações no seio das quais são implementadas. Cabe-lhes um papel determinante na interacção com os Cuidados Primários de Saúde, na formação médica continuada e de outros profissionais de saúde e na recepção e orientação dos doentes referenciados para a especialidade.São ainda necessários esforços redobrados para a identificação e controlo dos factores de risco e para o estabelecimento de estratégias de rastreio da disfunção ventricular na comunidade. Tal é passível de ser feito e é custo-eficiente, mas exige a colaboração de técnicos de saúde, investigadores e poder político para avaliar das necessidades reais, implementar e controlar a qualidade destas estratégias, sem as quais não conseguiremos conter a epidemia. SUMMARY: Despite there has been substantial progress in the treatment of heart failure over the last several decades, it is the only cardiovascular disorder that continues to increase in both prevalence and incidence. Characterised by very poor survival and quality of life heart failure is responsible for among the highest healthcare costs for single conditions in developed countries. Heart failure is therefore becoming an increasing concern to healthcare worldwide and must be a priority to National Health Services. It is already called the epidemic of the 21 st century. A correct diagnosis is the cornerstone leading to effective management of the syndrome. An early, accurate and complete diagnosis has become crucial with the identification of therapies that can delay or reverse disease progression and improve both morbidity and mortality. Diagnostic methods may need to encompass screening strategies, as well as symptomatic case identification. Until now, investigation has been over focused on pharmacological treatment; relatively little work has been done on assessing diagnostic tools. This is actually a difficult condition to diagnose at all levels of care, and misdiagnosis must be the first barrier to the control of the epidemic. AIMS Considering current and up-dated knowledge and ourown experience we analyse the problems in diagnosing heart failure and cardiac dysfunction and how they affect patient’s clinical outcome and public health care. It was our aim to analyse how increasing knowledge about cardiac dysfunction influenced the concept of heart failure, its definition and diagnostic criteria; the problems resulting from the use of non consensual definitions and diagnostic criteria; the role of clinical data and diagnostic tests on the diagnosis of the syndrome and on the screening for cardiac dysfunction in the community; to discuss best strategies to enhance diagnostic management of heart failure in all its spectrum, in order to halt the epidemic in the near future. METHODS: The investigation on which the present dissertation is based was developed progressively, along the years, during our every-day clinical practice. Various original clinical investigations and review papers, related to challenges in heart failure management and especially to diagnosis, were presented in scientific meetings and/or published gradually as partial results were obtained. The EPICA Programme (epidemiology of heart failure and awareness), a large-scale epidemiological study on heart failure in Portugal, addressed as secondary endpoints, problems of heart failure misdiagnosis in primary care and the value of clinics and different diagnostic tests to confirme or refute the diagnosis of the syndrome suspected on clinical grounds. But problems on the diagnosis of heart failure are not confined to primary care. Therefore, under the auspices of the Working Group of Heart Failure of the Portuguese Society of Cardiology, a survey on the management of heart failure at hospital was addressed to the heads of Portuguese Cardiology and Internal Medicine Wards. Compliance with Guidelines on diagnosis and treatment of heart failure, perceived difficulties and requests to a better management of the syndrome were ascertained. We have then explored the validity of a coded diagnosis of heart failure at death/discharge from the Department of Medicine of S. Francisco Xavier Hospital, and the rate of misdiagnosis. Gains on compliance with Guidelines on the diagnosis and treatment of heart failure, before and after the implementation of an acute heart failure unit in this Department were assessed. We also compared the performance of type-B natriuretic peptides – BNP and NT-proBNP – on systolic and diastolic heart failure diagnosis, in order to implement the more adequate test. In this thesis we discuss our published papers against the state of the art on heart failure diagnosis, and actual consequences of misdiagnosing. We revisit the accuracy of the different diagnostic testes to a definite diagnosis of the disease. Finally we analyse the different ways of screening for cardiac TESE3 AF 6/9/08 12:25 PM Page 309 310 Summary dysfunction and the more cost-efficient strategies to enhance heart failure diagnosis and management. RESULTS Since 1982, at the very beginning of our clinical activity, already aware of the complexity of the management of heart failure, we were involved in the development of an original pathophysiological heart failure classification, theme of Professor Fátima Ceia Doctoral Thesis discussed in 1989. Paper 1 - Heart Failure. New pathophysiological approach to therapy – published in 1984, described heart failure as a systemic disease resulting from the interaction of the different compensatory mechanisms. We proposed a new dynamic, pathophysiological and aetiological approach to the diagnosis of heart failure syndromes, based on clinics and conventional non-invasive assessment with drug management implications. In 1994, in paper 2 – Heart failure and the physician - towards the XXI century – we discussed the way how the compensatory mechanisms interact, produce the different heart failure syndromes and affect the evolution of the disease. Changing definitions according to the knowledge of the pathophysiology of heart failure at that time were revisited. The need for a universally accepted definition leading to early and accurate diagnosis and treatment of the syndrome was pointed-out. We called for strategies to prevent heart failure. In an up-dated review titled: Heart failure: from pathophysiology to clinics – a model in constant evolution – we revisit the changing pathophysiological models of heart failure – cardio-renal, haemodynamic, neuro-hormonal and imuno-inflamatory models - and their influence on the definition of the syndrome. Traditional dicotomization of heart failure in systolic and diastolic dysfunction is discussed. Rather than being considered as separate diseases with a distinct pathophysiology, systolic and diastolic heart failure may be merely different clinical presentations within a phenotypic spectrum of one and the same disease. Implications for the definition and diagnosis of heart failure are self evident. In chapter II – The diagnosis of heart failure: problems and foreseeable consequences - we analyse epidemiological, clinical and financial consequences of non consensual definition and diagnostic criteria of heart failure for individual patients, Healthcare Systems and Public Health. Problems resulting from the absence of a universally accepted definition of heart failure are clearly illustrated by current epidemiological data and were revisited in paper 3 – Epidemiology of heart failure. In various epidemiological studies measured prevalence and incidence of the syndrome diverge significantly. This worrying variation is certainly more due to different definitions and used diagnostic criteria than true differences between populations. We faced these difficulties when we had to design the EPICA programme, a large population-based study where we had to define simple, effective and easy to obtain diagnostic criteria of heart failure, for the whole spectrum of the disease, in primary care setting. The problem grew when we focused on heart failure with normal ejection function where diagnostic criteria were far from consensual. Therefore large trials on heart failure with normal ejection fraction and consensual evidence-based Guidelines on diagnosis and treatment of diastolic heart failure are still missing. Paper 4 – Prevalence of heart failure in Portugal - presents the design of the EPICA Programme. The EPICA study was one of the first large epidemiological studies addressing the prevalence of global heart failure, in the community, according to the European Guidelines for the diagnosis of the syndrome. We had to define simple, precise echocardiographic criteria to confirm a suspected diagnosis of heart failure on clinical grounds, in all its spectrum. At that time, Guidelines for heart failure with normal ejection fraction where far from consensual and non applicable to the ambulatory. In paper 5 - Prevalence of heart failure in Southwestern Europe: the EPICA study - we reported the prevalence of heart failure in mainland Portugal. From 5434 attendants of primary care centres, representative of the Portuguese population above 25 years, 551 had heart failure, leading to a prevalence of global heart failure of 4.35%, increasing sharply with age in both genders; 1.36% had systolic dysfunction and 1.7% normal ejection fraction. TESE3 AF 6/9/08 12:25 PM Page 310 Summary 311 In paper 6 – Epidemiology of heart failure in primary care in Madeira: the EPICA-RAM study - we report an overall prevalence of heart failure of 4.69%, with systolic dysfunction in 0.76% and with a normal ejection fraction in 2.74% of the cases. Discrepancies in the prevalence of the different types of heart failure between mainland and Madeira are probably related to different Public Health Care organization. Both studies showed that only half of the patients with a suspected diagnosis of heart failure on clinical grounds had the diagnosis confirmed by objective evidence of cardiac dysfunction. It’s therefore probable that unnecessary drugs were prescribed to patients who didn’t need them while others, who would benefit, were not correctly treated for heart failure. Paper 7 – Diagnosis of heart failure in primary care – is a review of the state of the art of the diagnosis of heart failure in primary care setting. It focused on main challenges faced by primary care physicians, namely difficulties on the access to imaging and strategies to screen for cardiac dysfunction. General practitioners awareness and training on the diagnosis and treatment of the syndrome are crucial to halt the epidemic. But problems on the diagnosis of heart failure are not exclusive of primary care. Heart failure is the first cause of hospitalization of patients above 65 years in medical wards, and accounts for more than 70% of the costs with the syndrome. In paper 9 – Validity of a diagnosis of heart failure: implications of misdiagnosing – we reported a prevalence of heart failure in patients hospitalized in our Medicine Department, during a six month period, of 17%. The diagnosis was actually sub-coded at death /discharge. The accuracy of the death / discharge coded diagnosis was 72.2%; the syndrome was under-diagnosed in 21.1% of the cases and over-diagnosed in 8.3%. The discharge codes failed a significant percentage of heart failure cases, biased the actual burden of the syndrome and compromise the allocation of resources to manage in-hospital heart failure and to develop specialised programmes of interaction with primary care. In paper 8 – Treatment of heart failure in Portuguese hospitals: results of a questionnaire – everybody reported difficulties in the management of heart failure. Heads of Cardiology Wards needed more specialised physicians and nurses as well as specific heart failure units for the management of the syndrome, and Heads of Internal Medicine Wards demand more facilities, easier access to echocardiography, and support from heart failure specialised cardiologists. Difficulties in the diagnosis of heart failure at all levels of care, have huge epidemiological, clinical and economic consequences for the individual patient, National Health Services and Public Health. In chapter III, we revisit the relevance of a complete diagnosis of heart failure. An appraisal based on symptoms alone is clearly an incomplete and inaccurate representation of the severity of cardiovascular disease. Determination of cardiac status requires evaluation of composite etiologic, anatomic, and physiologic diagnoses. Functional class and comorbidities must complement the diagnosis, leading to the more appropriate and individualized treatment. Aware of the uncertainty of the diagnosis of heart failure in primary care setting and of the role of General Practitioners in the management of the syndrome, we have evaluated in pre-specified substudies of the EPICA programme, the accuracy of clinics and tests available to the diagnosis of heart failure in the community. Paper 10 – The diagnosis of heart failure in primary care: value of symptoms and signs – confirmed that symptoms and signs and clinical history have limited value in diagnosing heart failure when used alone. The signs and symptoms that best predicted a diagnosis of heart failure were those associated with more severe disease. Among current symptoms, the history of paroxysmal nocturnal dyspnoea (LR 35.5), orthopnea (LR 39.1) and dyspnoea when walking on the flat (LR 25.8) were associated with a diagnosis of heart failure. However, these symptoms were not frequent within this population (sensitivity < 36%). Jugular pressure > 6 cm with hepatic enlargement, and oedema of the lower limbs (LR 130.3), a ventricular gallop (LR 30.0), a heart rate above 110 bpm (LR 26.7), and rales (LR 23.3), were all associated with a diagnosis of heart failure but TESE3 AF 6/9/08 12:25 PM Page 311 312 Summary were infrequent findings (sensitivity < 10%). Prior use of digoxin (LR 24.9) and/or diuretics (LR 10.6), an history of coronary artery disease (LR 7.1) or of pulmonary oedema (LR 54.2) were also associated with a greater likelihood of having heart failure. In paper 11 – Aetiology, comorbidity and drug therapy of chronic heart failure in the real world: the EPICA substudy – aetiological features and therapy relevant comorbidities were analysed. Hypertension was the more frequent risk factor/aetiology of heart failure in the community in Portugal (about 80%). Thirty nine percent had an history of coronary artery disease, and 15% had atrial fibrillation. In paper 12 – The value of electrocardiogram and X-ray for confirming or refuting a suspected diagnosis of heart failure in the community – we reported that ECG and X-ray features are not sufficient to allow heart failure to be reliably predicted in the community. Twenty five percent of patients with heart failure had a normal ECG or chest X-ray. In paper 13 – Evaluation of the performance and concordance of clinical questionnaires for heart failure in the primary care – we compared the accuracy of seven clinical questionnaires and scores for the diagnosis of heart failure in the community, and their concordance. Concordance was good between most of the questionnaires. Their low sensibility impairs their usefulness as diagnostic instruments, but their high specificity (>90%) makes them useful for the identification of patients with symptoms and signs from non-cardiac cause. In paper 14 – Epidemiology of heart failure in mainland Portugal: new data from the EPICA study -characteristics of patients with a definite diagnosis of heart failure and of those in whom the diagnosis of heart failure suspected on clinical grounds was excluded (false positive) were compared. The laters were older, more frequently women, had excessive weight, and a history of coronary artery disease was less frequent. Clinics, ECG and chest X-ray could not distinguish patients with heart failure due to systolic dysfunction from those with normal ejection fraction. Considering the limited and costly access to echocardiography in the community we address in paper 15 - the diagnostic challenge of heart failure with preserved systolic function in primary care: an EPICA-RAM substudy. The performance of BNP as a predictor of a diagnosis of heart failure with preserved systolic function according to ESC Guidelines, left ventricular hypertrophy and dilated left atria by echocardiography was tested. BNP was a good predictor of a dilated left atria, but not of the diagnosis of heart failure with preserved systolic function or of left ventricular hypertrophy (AUC: 0.89, 0.56, and 0.54 respectively). We conclude that BNP measurement alone was not a suitable screening test for heart failure with normal ejection fraction in the community, at least in patients with no or mild symptoms.In paper 16 – Comparative value of BNP and NTproBNP on the diagnosis of heart failure – we first established normal values and cut-offs for our laboratory.Then we assess the diagnostic accuracy of both peptides for the in-hospital diagnosis of heart failure due to systolic dysfunction and with normal ejection fraction. BNP and NT-proBNP had an excellent and similar accuracy to the diagnosis of both types of symptomatic heart failure, but none could distinguish patients with systolic heart failure from those with normal ejection fraction. We revisited the role of the various tests on the diagnosis of heart failure with systolic dysfunction, and with normal ejection fraction and discussed the more recent International Guidelines. There is a great piece of evidence that early treatment of asymptomatic left ventricular systolic dysfunction is cost-effective. Therefore, several screening strategies were investigated. ECG and type B natriuretic peptides measurements, alone or as part of clinical scores, allowed cost-effective community-based screening for left ventricular systolic dysfunction, especially in high-risk subjects. A programme including hand-held echocardiography, following NT-proBNP or ECG pre-screening prior to traditional echocardiogram was the most cost-effective.Screening strategies for left ventricular dysfunction proved no more costly than existing screening programmes such as those for cervical or breast cancer. Conversely, as far as we know, there is no proven strategy to efficiently screen for diastolic dysfunction in the community.Finally we discuss perspectives for heart failure TESE3 AF 6/9/08 12:25 PM Page 312 Summary 313 management in the near future. Simple, reliable and consensual diagnostic procedures are crucial to evaluate the actual burden of the disease, to comply with Guidelines and to reduce healthcare utilisation and costs. As the management of the syndrome in primary care has been hampered by perceived difficulties in diagnosis, improving diagnostic skills is essential and remains a continuous challenge for primary care clinicians. Moreover, patients may require more investigations and treatments that may not be available or very familiar to General Practitioners. Shared care is therefore necessary. Disease management programmes when available and accessible, are the preferred choice to address this issue. This multidisciplinary model of care delivered in specialized heart failure clinics, heart failure day hospitals and many other heart failure care stru-ctures, have shown success in improving quality of life, and reducing morbi-mortality and costs. In paper 17 - Translating Guidelines into clinical practice: benefits of an acute heart failure unit - we report a better compliance with Guidelines on diagnosis and treatment of heart failure after the implementation of a specialized heart failure unit in our Internal Medicine Department. We defend the implementation of heart failure programme management networks to provide optimal care for both patients and health care providers. They may consist of different structures to better address the needs of the referred patient, the referral physician and the regional health care system, and should have a crucial role in transition between primary and secondary care. Managing heart failure requires resources across the entire spectrum of care. Strategies to prevent heart failure include both primary and secondary prevention, and should encompass risk factors control and screening strategies for cardiac dysfunction in the community. Screening for high risk patients and, at least, for patients with asymptomatic systolic dysfunction is cost effective. Therefore, to improve heart failure outcomes and halt the epidemic, this will require shared efforts from investigators, clinicians and politicians. Health care strategy with adequate funding are imperative for successfull heart failure management. RÉSUMÉ: L’insuffisance cardiaque, déjà appelée d’épidémie du XXIeme siècle, est un problème de Santé Publique partout en Europe. Malgré les immenses progrès faits dans le domaine du traitement, dans les deux dernières décennies, l’insuffisance cardiaque est parmi les maladies cardiovasculaires la seule dont l’incidence et prévalence ne cessent d’augmenter. Ses principales caractéristiques sont une mortalité très élevée -supérieure à celle de l’ensemble des cancers - et un impact économique considérable sur les Systèmes de Santé. La prise en charge des insuffisants cardiaques doit ainsi être envisagée comme une priorité absolue. Toutefois, et bien que la sévérité de la situation soit universellement reconnue, Gouvernements et Systèmes de Santé n’ont pris que très peu de mesures concrètes, visant à freiner l’épidémie qui ne cesse de croître. Nous pouvons aujourd’hui prévenir et, sinon guérir l’insuffisance cardiaque, du moins la traiter de façon à freiner la progression de la maladie, ainsi nous soyons capables de faire le diagnostique à temps. Toute attitude térapêutique présume un diagnostique précoce et complet de la situation, sans lequel nulle attitude correcte ne pourra être prise. OBJECTIFS: Nous nous proposons analyser les problèmes du diagnostique de l’insuffisance cardiaque, à la lumière des connaissances actuelles et de notre propre expérience. Parmi les objectifs de ce travail, nous avons évalué la façon d’ont l’évolution des concepts d’insuffisance et de dysfonction cardiaque a influencé la définition et les critères de diagnostique, au cours des temps, et les conséquences du manque de consensus quant à la définition et aux critères de diagnostique pour les différentes phases d’évolution de la maladie. Nous avons discuté le rôle des symptômes, signaux et examens complémentaires dans le diagnostique de l'insuffisance cardiaque et dans les stratégies de screening de la dysfonction cardíaque. Finalement nous avons discuté quelques chemins et possibles stratégies à envisager pour la prise en charge de ces malades pour que, dans un future proche, nous soyons capables de mieux les traiter, mais aussi de mieux prévenir la maladie de façon à freiner l’épidémie. MÉTHODOLOGIE: La méthodologie utilisée pour ce travail dérive directement de l’expérience acquise dans la prise en charge des malades, et de l’investigation gérée par les difficultés perçues quant au diagnostique de l’insuffisance cardiaque, au long des années. Quand de l’élaboration de l’étude EPICA née de la nécessité d’obtenir des données épidémiologiques nationales en ce qui concerne l’insuffisance cardiaque au Portugal, nous avons conçu, selon un dessin original, un protocole d’investigation qui nous a permis d’évaluer la qualité du diagnostique de l’insuffisance cardiaque réalisé par les médecins de famille ainsi que le rôle des symptômes, des signaux, des données de l´histoire clinique, de l’électrocardiogramme e de la radiographie du thorax, dans le diagnostique de l’ insuffisance dans l’ambulatoire. Nous avons aussi investigué la qualité du diagnostique établi pendant l’hospitalisation. Nous avons déterminé la réelle prévalence de l’insuffisance cardíaque hospitalisée dans notre service au long de six mois et celle qui a été codifiée au moment de la sortie de l´hôpital. Nous avons encore comparé la qualité do diagnostique avant et après l’ouverture d’une unité d’insuffisance cardiaque et la performance des différents peptides natriurétiques dans le diagnostique du syndrome. Sous la forme de réponse à un questionnaire, qui leur a été adressé par le Groupe de Travail d’insuffisance cardiaque de la Société Portugaise de Cardiologie, sur la prise en charge de l’insuffisance cardiaque, les Directeurs des Services de Cardiologie et Médicine Interne de tout le Pays se sont prononcés sur à leurs difficultés, en ce qui concerne le diagnostique et le traitement de l’insuffisance cardiaque. Les résultats des investigations partielles ont été communiqués à la communauté scientifique et publiés dans les journaux de la spécialité, au long de ces dernières années. Cette dissertation est constituée par les papiers publiés et en publication auxquels nous avons additionné une révision de l’état actuel de l’art du diagnostique de l’insuffisance cardiaque, ainsi q’une réflexion sur les 317 TESE3 AF 6/9/08 12:25 PM Page 317 318 Résumé conséquences des difficultés éprouvées au diagnostique de la maladie et sur la manière d’améliorer la prise en charge de l’insuffisance cardiaque.RÉSULTATS: En 1982, l’hors de notre début d’activité, nous avons eu très tôt la perception de la complexité de l’insuffisance cardiaque et du défi que constituait, pour les cliniciens, la prise en charge de ces malades. Nous avons participé au développement d’une classification physiopathologique originale qui a servi de base pour le doctorat de la Professeur Fátima Ceia en 1989. L’article 1 – Insuffisance cardiaque : nouveaux concepts physiopathologiques et leurs applications thérapeutiques – publié en 1984, nous décrivons déjà l’insuffisance cardiaque comme une maladie systémique, résultat de l’interaction des différents mécanismes de compensation de la dysfonction cardiaque. Nous proposons « une classification physiopathologique avec application thérapeutique » originale, où nous définissons les différents types d’insuffisance cardiaque et leurs caractéristiques cliniques, hémodynamiques, fonctionnelles et anatomiques et proposons un traitement individualisé d’accord avec la définition et le diagnostique de chacun de ces différents types d’insuffisance cardiaque. En 1994, l’article 2 – L’insuffisance cardiaque et le clinicien à la fin du XXème siècle – fait une description détaillée de comment les différents mécanismes de compensation interagissent, influencent l’évolution de la maladie, produisent les différents syndromes et justifient le choix du type de traitement. Nous discutons l’évolution de la définition de la maladie d’accord avec l’évolution de l’investigation et une meilleure connaissance de la physiopathologie de la dysfonction cardiaque. Nous soulignons la nécessité du diagnostique et du traitement précoces et quant urgent il est de développer des stratégies capables de prévenir la maladie. Les investigateurs défendent aussi l’existence d’un continu entre l’insuffisance cardiaque à fraction d’éjection normale e celle qui s’accompagne de dysfonction systolique ventriculaire. Ce concept défend l’existence de plusieurs syndromes d’insuffisance cardiaque qui ne représenteront que des phénotypes différents d’une même maladie. Des nouvelles Recommandations pour le diagnostique et exclusion de l’insuffisance cardiaque à fraction d’éjection normale / dysfonction diastolique surgissent. Nous revisitons ces nouveaux concepts dans le chapitre: L’insuffisance cardiaque: de la physiopathologie à la clinique - un modèle en constante évolution. Au chapitre II – Le diagnostique de l’insuffisance cardiaque: problèmes et conséquences prévisibles - nous analysons les conséquences du manque de critères de diagnostique consensuels pour l’insuffisance cardiaque au long de tout son spectre. Les difficultés avec le diagnostique se répercutent sur les résultats des grandes études épidémiologiques. Nous avons senti cette difficulté quand, lors de l’élaboration du programme EPICA – ÉPidémiologie de l’Insuffisance Cardiaque et Apprentissage - nous avons voulu définir les critères pour le diagnostique de l’insuffisance cardiaque de tous les types, applicables à l’ambulatoire et d’accord avec les Recommandations Internationales. L’article 3 - Épidémiologie de l’insuffisance cardiaque – analyse les conséquences des différentes définitions et critères de diagnostique utilisés dans les grandes études épidémiologiques qui, au long des années, ont publié des prévalences et incidences très variables de l’insuffisance cardiaque. Ce problème s’aggrave encore quand il s’agit de l’épidémiologie de l’insuffisance cardiaque à fraction d’éjection normale ou dysfonction diastolique, ou des stratégies pour le screening de la dysfonction cardiaque asymptomatique, situations à définitions et critères encore moins consensuels. L’inexistence de Recommandations appuyées sur l’évidence, pour le traitement de l’insufisance cardiaque à fraction d’éjection normale ou à dysfonction diastolique, est une autre des conséquences de ces difficultés. C’est ainsi que des différences de méthodologie, de définitions et de critères de diagnostique, plutôt que des différences réelles entre les populations, difficultent notre connaissance quant à la réelle surcharge que l’insuffisance cardiaque et la dysfonction cardiaque imposent au Système National de Santé. Il est ainsi difficile de prévoir les recours nécessaires, à attribuer à une situation qui est mal connue. L’ article 4 – Prévalence de l’insuffisance cardiaque au Portugal – présente le dessin des études EPICA et EPICA-RAM. EPICA a été l’une des premières études TESE3 AF 6/9/08 12:25 PM Page 318 Résumé 319 à évaluer la prévalence de l’insuffisance cardiaque symptomatique globale, de l’ambulatoire, suivant les Recommandations de la Société Européenne de Cardiologie pour le diagnostique de l’insuffisance cardiaque. Nous y définissons des critères echocardiographiques précis pour tous les types d’insuffisance cardiaque, notamment celle à fraction d’éjection normale, alors qu’à l’époque il n’y avait pas encore de Recommandations consensuelles pour le diagnostic de cette situation. L’article 5 – Prevalence of chronic heart failure in Southwestern Europe : the EPICA study - relate la prévalence de l’insuffisance cardiaque au Portugal continental en 1998. Dans une population de 5434 individus âgés de plus 25 ans, représentative de la population portugaise nous avons identifié 551 cas d’insuffisance cardiaque, correspondant à une prévalence de 4,3%, qui augmente avec l´âge, chez les deux genres ; chez 1,3% la dysfonction ventriculaire est systolique, alors que 1,75% ont une fraction d’éjection normale. L’article 6 – Epidemiology of chronic heart failure in Primary Care in the Autonomic Region of Madeira: the EPICA-RAM study – a suivi le même protocole d’investigation et relate une prévalence de l’insuffisance cardiaque globale de 4,69%, 0,76 % à dysfonction ventriculaire systolique et 2,74% à fraction d’éjection normale. Ces deux études confirment que quand le diagnostique est suspecté par la clinique il ne se confirme objectivement qu’en la moitié des cas, ce qui fait supposer que beaucoup de malades seront sous médication inappropriée pour l’insuffisance cardiaque alors que d’autres, qui auraient tout intérêt à la faire, en seront probablement privés. L’article 7 – Diagnosis of chronic heart failure in Primary Care - revoit l’état de l’art quant au diagnostique de l’insuffisance cardiaque dans la communauté et discute les principaux défis auxquels les médecins de famille sont soumis, notamment les difficultés d’accès aux examens complémentaires de diagnostique et le screening de la dysfonction cardiaque asymptomatique dans la population en général. Mais les problèmes de diagnostique de l’insuffisance cardiaque, se posent transversalement à tous les niveaux, à l’hôpital comme chez le médecin de famille. Bien que l’insuffisance cardiaque soit la première cause d’hospitalisation après les 65 ans, responsable pour la plupart des coûts consommés par le syndrome, le diagnostique y est sous-estimé. L’article 9 – Validity of a diagnosis of heart failure : implications of misdiagnosing – démontre que l’insuffisance cardiaque a été la première cause d’hospitalisation dans notre service, pendant une période de six mois, ayant une prévalence de 17% et a été largement sous codifiée. La sous codification du diagnostique ne fait que diminuer le vrai poids du syndrome, menant à l’allocation incorrecte de recours pour la prise en charge de l’insuffisance cardiaque à l´hôpital et pour l’établissement de programmes capables de faire l’indispensable interface avec l’ambulatoire. En réponse au questionnaire sur la prise en charge de l’insuffisance cardiaque, que nous résumons dans l’article 8 – Traitement de l’insuffisance cardiaque dans les hôpitaux portugais : résultats d’un questionnaire - les Directeurs des Services de Médicine Interne ont relaté leurs difficultés d’accès à l’échocardiographie en temps utile et réclamé plus de collaboration du cardiologue; les Directeurs des Services de Cardiologie demandent plus de spécialistes et de structures vocationnées pour le diagnostique et traitement de l’insuffisance cardiaque. Les difficultés posées par le diagnostique de l’insuffisance cardiaque à tous les niveaux de soins, entraînent des conséquences épidémiologiques, socioéconomiques et financières néfastes pour le patient, la planification du Système National de Santé et la Santé Publique. Au chapitre III nous rappelons l’importance du diagnostique complet de l’insuffisance cardiaque. Au diagnostique anatomique, fonctionnel et du syndrome, il faut absolument joindre l’étiologie, la classe fonctionnelle e les comorbidités qui conditionnent souvent l’interprétation des testes de diagnostique, le traitement et le pronostique. Conscients des difficultés éprouvées para les médecins de famille, pour diagnostiquer correctement et en temps utile l’insuffisance cardiaque dans l’ambulatoire, et du rôle de ces Spécialistes en ce qui concerne la contention de l’épidémie, nous nous sommes proposés, comme objectifs secondaires de l’étude EPICA,d’investiguer la performance des instruments de diagnostique disponibles et à portée de ces cliniciens. L’article 10 – The diagnosis of heart failure in primary TESE3 AF 6/9/08 12:25 PM Page 319 320 Résumé care: value of symptoms and signs – documente les limitations des symptômes, signaux et des données cliniques, quand utilisés de forme isolée, pour le diagnostique de l’insuffisance cardiaque. Ils sont tous peu sensibles et ceux qui ont la plus grande valeur prédictive sont ceux qui s’associent aux formes congestives, plus graves, de la maladie: la dyspnée paroxysmale nocturne (LR 35,5), l’orthopnée (LR 39,1), la difficulté respiratoire pendant la marche en plan horizontal (LR 25,8), l’ ingurgitation jugulaire > 6 cm accompagnée d’ hépatomégalie e d’oedème des membres inférieurs (LR 130,3), le galop ventriculaire (LR 30,0), la tachycardie >110ppm (LR 26,7) et les crépitations pulmonaires (LR 23,3) sont ainsi associés au diagnostique, mais sont très peu fréquents chez les insuffisants cardiaques tout venant de l’ambulatoire. Un traitement antérieur avec du diurétique (LR 10,6) ou de la digoxine (LR 24,9), ou encore un épisode antérieur d’oédeme pulmonaire aigu (LR 54,2), sont d’autres prédicteurs du diagnostique. L’article 11 – Aetiology, comorbidity and drug therapy of chronic heart failure in the real world: the EPICA substudy – confirme que l´hypertension artérielle est, d’entre tous les facteurs de risque, la principale étiologie de l’insuffisance cardiaque dans l’ambulatoire au Portugal (80%). Trente neuf pourcent des malades inclus dans l’étude EPICA avaient une histoire de maladie coronarienne et 15% de fibrillation auriculaire. Nous avons encore analysé la comorbidité et son influence sur la prescription, en sachant que la prescription des médicaments recommandés pour l’insuffisance cardiaque est, au Portugal comme d’une forme générale en Europe, bien inférieur au désirable. L’article 12 - The value X- ray for confirming or refuting a suspected diagnosis of heart failure in the community – démontre que les données de l’électrocardiogramme e de la radiographie du thorax, par sois même, ne prédisent pas correctement le diagnostique de l’insuffisance cardiaque dans l’ambulatoire; 25% des insuffisants cardiaques inclus dans EPICA avaient un électrocardiogramme où une radiographie du thorax normal. Al’article 13 - Evaluation of the performance and concordance of clinical questionnaires for heart failure in primary care – nous avons comparé sept questionnaires ou scores cliniques habituellement utilisés pour le diagnostique de l’insuffisance cardiaque dans les grandes études épidémiologiques et de médicaments. Ils ont démontré avoir une concordance à peine raisonnable à bonne entre eux, et être très spécifiques (>90%) pour le diagnostique mais peu sensibles. Ils augmentent la probabilité du diagnostique de 4,3% prétest vers 25 à 30% post-test et se révèlent ainsi des instruments plus utiles dans l’exclusion d’une cause cardiaque pour les symptômes que pour le diagnostique de l’insuffisance cardiaque. L’article 14 – Épidémiologie de l’insuffisance cardiaque au Portugal continental : nouvelles données de l’étude EPICA – compare les caractéristiques des malades qui, ayant une clinique compatible avec le syndrome, ont été inclus dans EPICA mais n’avaient pas de dysfonction cardiaque objective (faux positifs), avec ceux qui ont eu leur diagnostique objectivement confirmé. Les premiers étaient plus âgés, il y avait plus de femmes, plus de poids excessif, moins de maladie coronarienne. L’investigation confirme encore que les données de l’électrocardiogramme e de la radiographie du torax ne distinguent pas les insuffisants cardiaques qui ont une dysfonction systolique ventriculaire de ceux qui ont une fraction d’éjection normale. Face au défi du diagnostique de l’insuffisance cardiaque à fraction d’éjection normale, aux difficultés d’accès à l’échocardiographie dans l’ambulatoire, au prix de l’examen et aux critères encore peu consensuels pour le diagnostique de cette situation, nous avons analysé et publié à l’article 15 – The diagnostic challenge of heart failure with preserved systolic function in primary care setting: an EPICA-RAM substudy - la valeur des peptides natriurétiques du type B, NTproBNP, comme test de triage des malades qui, parmi ceux qui présentent une clinique compatible avec le syndrome, devront confirmer objectivement le diagnostique par échocardiographie. Ainsi, nous avons évalué la performance du test comme prédicteur : du diagnostique d’insuffisance cardiaque à fraction d’éjection normale, selon les Recommandations internationales, d’hypertrophie ventriculaire gauche et de dilatation de l’auricule gauche. Le NT-proBNP n’à été bon prédicteur que de ce dernier paramètre, ce qui nous fait conclure que le test ne permet pas de trier les malades de façon à diminuer les nécessités d’échocardiographie face à une hypothèse clinique d’insuffisance cardiaque, du moins en ce qui concerne les cas peu évolués, fréquemment asymptomatiques, de TESE3 AF 6/9/08 12:25 PM Page 320 Résumé 321 l’ambulatoire. Nous avons aussi comparé la performance des peptides natriurétiques du type B - BNP et NT-proBNP – quant au diagnostique de l’insuffisance cardiaque symptomatique à dysfonction ventriculaire systolique et à fraction d’éjection normale, traitée à l’hôpital. Les résultats de cette investigation sont révélés dans l’article 16 – Comparative value of BNP and NT-proBNP for the diagnosis of heart failure. Les deux tests ont démontré une performance excelente et comparable dans le diagnostique du syndrome, mais aucun n’a été capable de distinguer les deux types d’insuffisance cardiaque. Nous avons revu et discuté l’état de l’art quant au rôle des différents examens complémentaires, notamment des peptides natriurétiques et de l’échocardiographie, dans le diagnostique des différents types d’insuffisance et de dysfonction cardiaque, ainsi que les toutes dernières Recommandations internationales. Nous avons analysé les stratégies proposées pour le screening de la dysfonction ventriculaire asymptomatique, qui est au moins aussi fréquente dans l’ambulatoire que l’insuffisance cardiaque symptomatique. Par ailleurs, l’évidence montre que le traitement précoce de la dysfonction ventriculaire asymptomatique, est efficace et diminue les coûts. Le gold standard pour le screening de la dysfonction ventriculaire imposerait la réalisation d’un échocardiogramme à toute la population, ce qui est incomportable. Plusieurs stratégies ont été investiguées, ces dernières années, à la recherche de celle qui sera la plus efficace tout en épargnant le plus possible. Tous affirment que aucun examen isolé ne pourra être suffisant pour ce screening. Par contre, l’électrocardiogramme et/ou les peptides natriurétiques, incorporés ou non en scores cliniques, sont souvent évoqués comme testes efficaces pour le pré-screening des patients à envoyer à l’échocardiographie. Son utilisation diminue le nombre ’échocardiogrammes nécessaires et la dépense, tout en étant au moins aussi efficace que le screening du cancer du sein ou du colle de l’utérus, exige un investissement qui n’est en rien supérieur. Quelques auteurs ont démontré que l'exécution d’un échocardiogramme qualitatif, fait avec un échocardiographe portable, après l’ECG ou la détermination du BNP/ NT-proBNP et avant l’échocardiogramme complet, améliore encore la stratégie pour le screening de la dysfonction cardiaque. Finalement nous terminons avec quelques commentaires concernant les perspectives futures pour la prise en charge de l’insuffisanc e cardiaque. Il est absolument urgent et primordial d’établir d’une définition précise et universelle, ainsi que de critères de diagnostique objectifs, simples et reproductibles, applicables à tout le spectre de l’insuffisance cardiaque, de façon à ce que, dans un futur proche, nous soyons capables de connaître le véritable poids de l’insuffisance cardiaque, d’organiser une prise en charge le plus efficace possible tout en respectant l’inévitable contention des dépenses publiques. Les problèmes de diagnostique de l’ambulatoire exigent que les médecins de famille disposent de programmes de formation continus et que le dialogue avec l’hôpital et les spécialistes soit facilité, tel que nous l’avons fait, de forme programmée, systématiquement,pendant le programme EPICA. Les cliniques d’insuffisance cardiaque et les programmes structurés de prise en charge de l’insuffisance cardiaque ont démontré leur efficacité. Ils permettent une meilleure implémentation des Recommandations de diagnóstique et traitement, améliorent la qualité de vie et la survie des insuffisants cardiaques qui y sont suivis. Dans l’article 17 - Translating Guidelines into clinical practice : benefits of an acute heart failure unit - nous rendons compte de notre expérience en ce qui concerne les gains obtenus quant au diagnostic et traitement des insuffisants cardiaques hospitalisés dans notre service avant et après l’ouverture d’une unité d’insuffisance cardiaque et qui nous a permi d’amelliorer la qualité des soins prêtés à ces malades. Nous défendons que ces unités spécialement vocationnées pour la prise en charge de l’insuffisance cardiaque doivent se multiplier, s’intégrer en programmes plus vastes d’organisation de soins à prêter aux insuffisants cardiaques, qui incluent notamment l´hôpital de jour et adopter des structures variables d’accord avec les nécessités des populations qu’elles servent. Ces programmes de prise en charge de l’insuffisance cardiaque pourront assumer un rôle déterminant dans la formation scientifique des médecins, spécialement des médecins de famille, dans l’interface entre les soins primaires et l’hôpital et dans la référentiation des insuffisants cardiaques. Tous les efforts pour identifier et corriger précocement les facteurs de risque cardiovasculaire et développer TESE3 AF 6/9/08 12:25 PM Page 321 Résumé des stratégies pour le screening de la dysfonction cardiaque doivent être multipliés comme stratégies de prévention. Tout cela est possible, efficace à un pris semblable à celui d’autres programmes déjà en cours, mais exige la collaboration de tous, population, professionnels de santé, investigateurs et pouvoir politique qui viabilise l’évaluation des nécessités, le montage de ces programmes multidisciplinaires, et en contrôle la qualité, de façon à ce que très vite nous puissions contrôler cette épidémie.

Mental health promotion during pregnancy and early childhood : an action- research project in primary health care

ABSTRACT – Background: Primary Health Care (PHC) is usually the first contact with the health system, and health professionals are key mediators for enabling citizens to take care of their health. In Portugal, great improvements have been achieved in the biometric indicators of maternal and child health during the last decades. Nevertheless, scant attention has been paid to the mental health dimension, in spite of the recognition of its importance, being pregnancy and early childhood crucial opportunities in the lifecycle for mental health promotion, especially in the early years of life, with a strong impact in the health of the child. The impact of early attachment between mother and baby on maternal and child health has long been recognized. This attachment can be influenced by some factors, as the mother’s emotional adjustment. Attention to these factors may facilitate implementation of both positive conditions and preventative measures. Family support during the transition to parenthood has been highlighted as an effective measure and PHC professionals are in a privileged position as information sources as well as mediators. Aims: The project we present describes an action-research process developed together among academic researchers and health professionals to embrace these issues. We intend to enable health professionals to support families in the transition to parenthood thereby promoting children’s mental health. Approach: The project is driven by a participatory approach intended to lead to reorganization of health care during pregnancy and early childhood. Effective change happens when those involved are interested and motivated, what makes their participation so important. Reflection about current practices and needs, and knowledge about evidence-based interventions have been guiding the selection of changes to introduce in clinical practice for family support and development of parenthood skills and self-confidence. Development: We summarize the main steps in development: the initial assessment and the picture taken from the community under study; the decision making process; the training programme of PHC professionals in action; the review of the protocols of maternal consultation, home visits and antenatal education; the implementation planning; the plan for evaluation the effectiveness of the changes introduced in the delivery of maternal and child health care units. The already developed work has shown that motivation, leadership and organizational issues are decisive for process development.-------------------------- RESUMO - Os Cuidados de Saúde Primários são habitualmente o primeiro contacto com o sistema de saúde e os profissionais de saúde são mediadores chave na capacitação dos cidadãos para cuidarem da sua saúde. Em Portugal, nas últimas décadas, têm-se alcançado grandes melhorias nos indicadores biométricos de saúde materno-infantil. Contudo, tem-se dedicado pouca atenção à dimensão de saúde mental, apesar do reconhecimento da sua importância. A gravidez e primeira infância têm sido apontadas como uma oportunidade crucial no ciclo de vida para a promoção da saúde mental. É dado especial enfoque aos primeiros tempos de vida, dado o forte impacto na saúde da criança. O impacte da vinculação precoce entre a mãe e o bebé na saúde da mãe e da criança há muito que é reconhecido. Esta vinculação pode ser influenciada por vários factores, nomeadamente pelo ajustamento emocional da mãe. A focalização nestes aspectos pode facilitar a criação de condições favoráveis e a implementação de medidas preventivas. O suporte familiar durante o período de transição para a parentalidade tem sido enfatizado como uma medida eficaz e os Cuidados de Saúde Primários estão numa posição privilegiada como fontes de informação e como mediadores. O projecto que apresentamos descreve um processo de investigação- acção desenvolvido em parceria entre investigadores académicos e profissionais de saúde para abordar os aspectos referidos. Pretende-se capacitar os profissionais de saúde para apoiarem as famílias na transição para a parentalidade, promovendo assim a saúde mental das crianças. O projecto baseia-se numa abordagem participativa, direccionada para a reorganização dos cuidados durante a gravidez e primeiros tempos de vida. A mudança efectiva acontece quando os envolvidos estão interessados e motivados, o que torna a sua participação tão importante. A reflexão acerca das práticas e necessidades actuais e o conhecimento acerca de intervenções baseadas na evidência têm guiado a selecção das alterações a introduzir na prática clínica, no sentido de promover o suporte familiar e o desenvolvimento de competências parentais e auto-confiança. Neste artigo, apresentamos as etapas principais do desenvolvimento do projecto: avaliação inicial da comunidade em estudo; processo de tomada de decisão; programa de formação dos profissionais dos Cuidados de Saúde Primários; revisão dos protocolos da consulta de saúde materna, visita domiciliária e educação pré-natal; planeamento da implementação; plano de avaliação da efectividade das alterações introduzidas na prestação de cuidados. O trabalho já desenvolvido tem mostrado que a motivação, liderança e aspectos

A Review of National Guidelines for Management of COPD in Europe

The quality of care can be improved by the development and implementation of evidence-based treatment guidelines. Different national guidelines for chronic obstructive pulmonary disease (COPD) exist in Europe and relevant differences may exist among them.This was an evaluation of COPD treatment guidelines published in Europe and Russia in the past 7 years. Each guideline was reviewed in detail and information about the most important aspects of patient diagnosis, risk stratification and pharmacotherapy was extracted following a standardised process. Guidelines were available from the Czech Republic, England and Wales, Finland, France, Germany, Italy, Poland, Portugal, Russia, Spain and Sweden. The treatment goals, criteria for COPD diagnosis, consideration of comorbidities in treatment selection and support for use of long-acting bronchodilators, were similar across treatment guidelines. There were differences in measures used for stratification of disease severity, consideration of patient phenotypes, criteria for the use of inhaled corticosteroids and recommendations for other medications (e.g. theophylline and mucolytics) in addition to bronchodilators.There is generally good agreement on treatment goals, criteria for diagnosis of COPD and use of long-acting bronchodilators as the cornerstone of treatment among guidelines for COPD management in Europe and Russia. However, there are differences in the definitions of patient subgroups and other recommended treatments.

Implementation of a pilot project for the treatment and prevention of substance abuse in children and adolescents : strengthening families for parents and youths 12-16

RESUMO: Antecendentes: Uma avaliação dos serviços de abuso de substâncias em Barbados identificou a necessidade de programas e serviços que são projetados especificamente para crianças e adolescentes. Objetivo: Realizar programa com base em evidências para reduzir a incidência de abuso de drogas entre crianças e adolescentes por meio do fortalecimento da unidade familiar através de parentalidade positiva, de maior funcionamento familiar e de resistência dos jovens. Método: Dois projetos-piloto foram realizadas com base no programa "Fortalecer as Famílias para Pais e Jovens de 12 a 16 anos (SFPY). O programa de nove semanas foi empregado como uma intervenção para criar laços familiares mais fortes, aumentar a resistência dos jovens e reduzir o abuso de drogas entre crianças e adolescentes de idades de 11 a 16 anos. A decisão foi tomada para incluir participantes de 11 anos desde que as crianças possam estar no primeiro ano da escola secundária nessa idade. IMPLEMENTATION OF SUBSTANCE ABUSE PILOT PROJECT FOR CHILDREN AND ADOLESCENTS 5 Resultados: Quinze famílias participaram em dois projetos-piloto e a avaliação final mostrou que os jovens após o programa, geralmente tornaram-se mais positivos sobre o seu lugar na unidade familiar e sentiram que sua participação no programa foi benéfica. Os pais, da mesma forma, relataram que eles conquistaram, com o programa uma relação mais positiva, uma melhor compreensão das necessidades, e consciência das mudanças de desenvolvimento de seus jovens. Desta forma, considera-se que o programa atingiu o resultado desejado de criar unidades familiares mais fortes. Conclusão: O Projeto Piloto “SFPY” foi bem sucedido em fazer pais e jovens mais conscientes de suas necessidades individuais e de responsabilidades dentro da unidade familiar. Como resultado, o relacionamentos das respectivas famílias melhorou. Estudos baseados em evidências têm demonstrado que um relação familiar mais forte diminui a incidência de uso e abuso de drogas na população adolescente, aumentando os fatores de proteção e diminuindo os fatores de risco. A implementação do programa, que foi desenvolvido e testado no ambiente norte-americano, demonstrou que era transferível para a sociedade de Barbados. No entanto, seu impacto total só pode ser determinado através de um estudo comparativo envolvendo um grupo de controle e / ou uma intervenção alternativa ao abuso de substâncias. Portanto, é recomendável que um estudo comparativo da intervenção SFPY deve envolver uma amostra representativa de adolescentes que estão em estágio de desenvolvimento anterior mais cedo. Evidências já demonstram que o programa é mais eficaz, com impacto mais longo sobre os jovens que participam em uma idade maisABSTRACT:Background: An evaluation of substance abuse services in Barbados has identified the need for programmes and services that are specifically designed for children and adolescents. Aim: To conduct an evidence-based programme to reduce the incidence of substance abuse among children and adolescents by strengthening the family unit through positive parenting, enhanced family functioning and youth resilience. Method: Two pilot projects were conducted based on the ‘Strengthening Families for Parents and Youths 12– 16’ (SFPY) programme. The nine-week programme was employed as an intervention to create stronger family connections, increase youth resiliency and reduce drug abuse among children and adolescents between the ages of 11 to 16. The decision was made to include participants from age 11 since children may be in the first year of secondary school at this age. IMPLEMENTATION OF SUBSTANCE ABUSE PILOT PROJECT FOR CHILDREN AND ADOLESCENTS 3 Results: Fifteen families participated in two pilot projects and an evaluation conducted at the conclusion showed that the youth were generally more positive about their perceived place in the family unit and felt that the being in the programme was generally beneficial. The parents similarly reported they had a more positive relationship with their youths and also had a better understanding of their needs, and an awareness of their developmental changes. This affirmed that the programme had achieved its desired outcome to create stronger family units. Conclusion: The SFPY Pilot Project was successful in making parents and youths more aware of their individual needs and responsibilities within the family unit. As a result relationships within their respective families were strengthened. Evidence-based studies have shown that enhanced family functioning decreases the incidence of substance use and abuse in the adolescent population by increasing protective factors and decreasing risk factors. The implementation of the programme, which was developed and tested in the North American environment, demonstrated that it was transferable to the Barbadian society. However, its full impact can only be determined through a comparative study involving a control group and/or an alternative substance abuse intervention. It is therefore recommended that a comparative study of the SFPY intervention should be delivered to a representative sample of adolescents who are at an earlier developmental stage. Evidence has shown that the programme is more effective, with longer impact on youths who participate at a younger age.

Traitement pharmacologique de la schizophrénie: évaluation comparative de la qualité des recommandations de pratique clinique [Comparative evaluation of clinical practice guidelines for the treatment of schizophrenia]

INTRODUCTION: Many clinical practice guidelines (CPG) have been published in reply to the development of the concept of "evidence-based medicine" (EBM) and as a solution to the difficulty of synthesizing and selecting relevant medical literature. Taking into account the expansion of new CPG, the question of choice arises: which CPG to consider in a given clinical situation? It is of primary importance to evaluate the quality of the CPG, but until recently, there has been no standardized tool of evaluation or comparison of the quality of the CPG. An instrument of evaluation of the quality of the CPG, called "AGREE" for appraisal of guidelines for research and evaluation was validated in 2002. AIM OF THE STUDY: The six principal CPG concerning the treatment of schizophrenia are compared with the help of the "AGREE" instrument: (1) "the Agence nationale pour le développement de l'évaluation médicale (ANDEM) recommendations"; (2) "The American Psychiatric Association (APA) practice guideline for the treatment of patients with schizophrenia"; (3) "The quick reference guide of APA practice guideline for the treatment of patients with schizophrenia"; (4) "The schizophrenia patient outcomes research team (PORT) treatment recommendations"; (5) "The Texas medication algorithm project (T-MAP)" and (6) "The expert consensus guideline for the treatment of schizophrenia". RESULTS: The results of our study were then compared with those of a similar investigation published in 2005, structured on 24 CPG tackling the treatment of schizophrenia. The "AGREE" tool was also used by two investigators in their study. In general, the scores of the two studies differed little and the two global evaluations of the CPG converged; however, each of the six CPG is perfectible. DISCUSSION: The rigour of elaboration of the six CPG was in general average. The consideration of the opinion of potential users was incomplete, and an effort made in the presentation of the recommendations would facilitate their clinical use. Moreover, there was little consideration by the authors regarding the applicability of the recommendations. CONCLUSION: Globally, two CPG are considered as strongly recommended: "the quick reference guide of the APA practice guideline for the treatment of patients with schizophrenia" and "the T-MAP".

NICaN Regional Supportive & Palliative Care Network

NICaN Regional Supportive & Palliative Care Network Friday 30th May 2008 Lecture Theatre, Fern House Antrim 2.00 pm - 5.00 pm Welcome, Introductions Stuart MacDonnell, Chair of the Supportive and Palliative Care network welcomed everyone to the meeting. This meeting had been rescheduled to accommodate the validation workshop for the regional palliative care model, which took place on Friday,18th April. Acknowledging the full agenda, several items were pulled forward to accommodate speakers SPC_0809_03 Modernisation and Reform of Supportive and Palliative care Mr MacDonnell welcomed Dr Sonja McIlfatrick and Dr Donna Fitzimons, members of the Phase 1 Project Team for the Modernisation and Reform of palliative care. Their presentation highlighted the journey taken by the Project Team since January 2008 - May 2008. Seeking to deliver the network vision, for any person with palliative care need, cancer or non - cancer, the project team incorporated several methodologies. The literature review identified best practice. An assessment of need including epidemiological data and review of service provision. Consultation reflected the engagement with patients, carers and professional forums, primary care and non-malignant focus groups. The breadth of consultation confirmed the evidence for the identified components of the model. These were validated at the April workshop. External review of the work was provided by Dr Phil Larkin (Galway Uni) Prof David Clark (End of Life Care Observatory, Lancaster University) and Mr Bob Neillans (Chair of the Mid Trent Palliative care network, which has been involved in the Delivering choice programme within Lincolnshire). The Guiding Principles of the model reinforced Patient and family centred care, enhanced community provision and supported by specialists. The components of the model are · Identification of patient with Palliative careened · Holistic Assessment · Integration of services · Coordination of care · End of Life Care and Bereavement Care The consultation process also highlighted the need for Increased Public and Professional Awareness. This was recognised as an encompassing component. Underpinning the model is the need for robust Education and common core values e.g. dignity, choice, advocacy, empowerment, partnership working. Stuart MacDonnell, who also chaired the steering group during the project, congratulated the Project Team for delivering the comprehensive document on schedule. The Report has been submitted to the NICaN Board and the DHSSPSNI. In addition, an outline for Phase 2 of this work has been submitted. Mr MacDonnell recognised that there is real opportunity for palliative care to benefit from the DHSSPSNI commitment to concrete developments. Phase 2 will progress the current high-level components of the model into quality services developments at a local level, demonstrating integration throughout. The methods propose continued engagement with the Delivering Choice Programme enabled through a Central and also Local Teams. The report and the Appendices care available on the NICaN website www.nican@n-i.nhs.uk SPC_0809_01 Chairman's Business · Update on the Cancer Service Framework, the document has been submitted and presented to the Departmental Programme Board. Next stages will include the review of costs and development of a implementation guidance It is hoped that the completed document should be available for public consultation in Autumn 2008. with a launch of the framework document and accompanying implementation guide in Spring 2009. Some funding has already been identified to advance key areas of work including, Advanced communication skills training, peer review and an appointment of a post to develop the cancerni.net, focusing on children and e-learning tools. · Children's and Adolescent Cancer network group , Liz Henderson is to convene a group to consider how this is to be taken forward. · NICaN appointments Recognition was given to the significant contribution made by Dr Gerard Daly during his position as NICaN Lead Clinician, particularly throughout the early establishment of the NICaN. Dr Dermott Hughes (Western Trust) has been appointed as the NICaN Medical Director. The Primary Care Director post has been advertised and it is hoped that the Director of Network will be advertised later in Summer. Endorsement of End of Life care paper. The Paper was presented and endorsed at the March 2008 NICaN Board meeting. Mr David Galloway (Director of Secondary Care) emphasised the need for this important work to be recognised within the regional model to ensure that it is reflected in future models of service delivery Congratulations were again echoed to the Chair of the End of Life Group for this work, Dr Glynis Henry, and the working group Other recognition Mr MacDonnell congratulated the significant achievements across the network. These include: · Dr Francis Robinson (Consultant Palliative Medicine, Western Trust) Awarded - Consultant of the year at the NI Health Care awards. · Mrs Evelyn Whittaker Hospice Nurse Specialist, NI Hospice, Joint Second Prize in the Development award within the International Journal of Palliative Nursing Awards, for her work in development of palliative care education in nursing homes. · Mr Ray Elder is the newly appointed Team Leader of Community Palliative care, SE Trust. · Mrs Bridget Denvir, who managed the establishment of one of the first community multiprofessional palliative care teams is moving to work with establishing integrated teams within the Belfast Trust. Bridget has been an active core member of the network and here contribution has been much appreciated. Mrs Sharon Barr will attend in future. SPC_0809_02 Minutes & matters Arising from Meeting, 13th December 2007 No amendments were made to the draft minutes from the December meeting. These will be posted on the NICaN website for future reference. Palliative Care Research Following consultation, the response to the business case for the All Ireland Institute was forwarded on 22 February 2008 to Prof David Clark. Prof Judith Hill informed the group that terms of tender are now being developed. Awareness raising across academic institutions continues to engage interest in potential partnerships. Atlantic Philantrophies have offered financial support to the venture and match funding is being sought from across jurisdictions. Previous discussions at Network meetings have endorsed the need to establish a work strand for research and development within palliative and end of life care. To identify the body of interested parties and explore the strengths and weaknesses of a collaborative model for research, a workshop, - Building collaboration for Palliative and End of life Care Research -will take place on 4 June 10am - 2pm.in the Comfort Hotel.Antrim, The workshop will be chaired by Prof David Clark, Director of the International Observatory on End of Life Care. Prof Shelia Payne, Help the Hospices Chair in Hospice Studies and co director of the Cancer Experiences Collaborative will present the Experiences and Results from Research Collaborative. Feedback from this event will be brought back to the next meeting in September. SPC_0809_04 Patient Information pathways - a pathway for advanced disease Ms Danny Sinclair, NICaN Regional Coordinator for Patient Information informed the network of how patient information pathways have been developed in line with the Cancer Services Collaborative. Emerging themes, with regard to information needs of patients with advanced disease, are being identified from the work undertaken across the tumour groups. It is important to identify all information needs to develop a generic pathway of information resources for advanced disease to be endorsed by the Supportive and Palliative care network. This could be used across the all tumour specific information pathways and across organisational boundaries. The resulting pathway could potentially be used for non- cancer condition. A group is to be established to take this work forward. The group will: · Develop a list of advanced disease information themes · .Identify when they become relevant for the patient or their carer · .Identify existing resources · .Develop resources where needed · .Participate or nominate when review is required Dr Sheila Kelly nominated Helen Hume (SETrust) Paula Kealey will also contribute to this work; a nomination from the Patient and Public Information Forum has also been identified. A date will be circulated across the network to engage further interest and establish group SPC_0809_08 Development of a Regional Syringe Driver Prescription Chart Ms Kathy Stephenson reported that the second consultation of the draft regional syringe driver prescription chart and the focus group discussions, Pilots of the chart are to be undertaken within Trust, Hospices and General Practices. SPC_0809_05 A framework for Generalist and Specialist Palliative and End of Life Care Competency Dr Kathleen Dunne, lead of the Education works strand, reported on the findings following consultation of the Education framework. The report was widely appreciated across the network and valued as a significant and timely document for the commissioning of generalist and specialist adult palliative care education. Mr MacDonnell congratulated Dr Dunne and the members of the education workstrand for developing the framework aligning its significance to the underpinning needs of the regional model Amendments will be made to the document and then forwarded to the NICaN Board for endorsement. A process of implementation will be explored and reported to the network group at the September meeting. Key target areas for generalist palliative care education were highlighted within care of the elderly and general medicine. . SPC_0809_06 Pallcareni.net-a website for people with palliative care needs Ms Danny Sinclair, reminded the group of the pending amalgamation of the CAPriCORN and NICaN website. The resulting new web address will be www. cancerni.net. Recurrent funding has been secured to ensure the development of the supportive and palliative care website.www.Pallcareni.net The new website will host good information for people with palliative care needs, regardless of diagnosis. It will be accessible via the cancerni.net portal or independently as the pallcareni portal. It will signpost people with palliative care needs to condition- specific websites. The website will also enable the communication needs of the NI Regional Supportive & Palliative Care Network. This is a very significant method of seeking to enable greater understanding of palliative care for public and professionals, as highlighted within the regional model. Currently the material from the CAPriCORN website is being migrated onto cancerni and /or pallcareni.net as appropriate. To enable the further development of this opportunity a steering group of interested individuals is to be established. Their role will be to: · Drive the development of the website so it meets the needs of public and professionals through the sourcing and development of additional content · Identify any support that is needed, e.g. technical support · Review the website as a whole as it grows (coordinating condition-specific developments) · Review the functions of the website to aid communication throughout the Supportive and Palliative care network The steering group representation should reflect the constituencies within the Supportive and Palliative Care network. Current expressions of interest have come from Heather Reid and Valerie Peacock. A date will be circulated across the network to engage further interest and establish group SPC_0809_07 Update of Guidelines workstrand Dr Pauline Wilkinson presented the current work within the guidelines workstrand. 1. Brief Holistic Assessment & Referral Criteria to Specialist Palliative Care The development of an Holistic assessment Tool will help to identify holistic need at generalist and specialist level. Recognition of complex need prompts appropriate referral to specialist palliative care. The regional referral form is compatible with the Minimum Data set. The final drafts of this work are to be circulated widely, inclusive of service framework groups, primary care, secondary care and the supportive and palliative care network. Consultation will take place during June and July. Piloting of the forms will also be undertaken. 2. Control of Pain in Cancer Patients The original guidelines where developed 2003 and are now ready for review. The Mapping exercise, undertaken in May 2007, highlighted that the Guidelines were poorly adopted. The group have reviewed the pending SIGN 2 guidelines for pain with regard to practice in Northern Ireland. These are highly evidence based and are due to be launched this Summer. Whilst an excellent resource their comprehensiveness limits their readability, this may result in poor compliance. The Guidelines group feel it is important to have accessible and user-friendly guidelines particularly for Generalists and Out of hours. There are examples of good work that has taken place across the province, but there is a need for regional consistency. Dr Wilkinson has contacted Dr Carolyn Harper (Deputy CMO) and GAIN with regard to enabling funding to progress this work. The Guidelines group hope to approach the NICaN Primary Care Group to work in collaboratively on this piece, based on the templates already available. The works should be available in both electronic and paper versions. 3. Care of the dying & Breaking bad news Dr Gail Johnston has now completed an Audit of the Care of the Dying Pathways within the EHSSB. Gail is also seeking to examine to what extent the Regional Guidelines for Breaking Bad News are being implemented in the EHSSB with a view to identifying the need for further training or organisational structures that would facilitate future uptake. 4. Advances in new Technology Syringe Drivers Dr Wilkinson reported on a presentation made to the guidelines group by Mr Jim Elliot, Principle Engineer, Cardiology & Ann McLean, and Macmillan Palliative Care Nurse RVH. There is increasing concern with regard to how devices meet the recommended safety standards and how to reduce error. New devices have 3 point checking, automatic detection of syringe, automatic flow rates, full range of alarms, battery status and data download to provide an event log. There are now 2 companies in UK who have devices that meet these safety criteria. The current Graseby syringe drivers, which have been on the market and used predominately within Northern Ireland over the past 27 years Most new devices are not compatible with the regionally available monoject syringe, however contractual changes will lead to the withdrawal of the monoject syringes in October 2008. The Guidelines group supports a regional approach to this matter. This was echoed in the Supportive and Palliative care network. An option appraisal, identifying costs, and training issues should be developed through the engagement with Trusts and DHSSPSNI. The issue of Patient safety should be raised with the DHSSPSNI. SPC_0809_09 Evaluation of Supportive and Palliative Care network Deferred to next meeting. . SPC_0809_10 Emerging Issues Mrs Anne Coyle, Bereavement Coordinator, Southern Trust, announced that the Regional Bereavement Strategy is soon to be released. Anne supported the close alignment between the content of the strategy and the work of the regional model and other workstrands within the Supportive and Palliative care network. Ms Eleanor Donaghy, Transplant Coordinator, briefly highlighted the issue of tissue donation. Each year Northern Ireland has a dearth of corneal donations. There is no upper age limit for donation and retrieval is not limited by a cancer diagnosis. Recipients do not require immunosuppressive and the transplant is lifelong. The National Blood Service provided coordination of this donation they may be contacted via 07659180773. It is hoped that Mrs Coyle and Ms Donaghy could provide more comprehensive presentations at a future meeting.

Good Practice Guides

This series of Good Practice Guides is designed to share important information about health inequalities and some of the evidence-based measures that can be taken to reduce the stark differences in health and wellbeing within populations. It is recognised that leadership and coordinated, effective action at a number of levels can reduce this gap. Ensuring concerted, evidence-based action on health and wellbeing inequalities demands the efforts of government, statutory organisations and the community, voluntary and private sectors. The Good Practice Guides were developed to inform and support joined-up working across these sectors. It is known that health inequalities are closely linked with degrees of social disadvantage and with the unequal distribution of power, income, goods and services. According to the World Health Organization, there are also powerful social and psychological factors and life circumstances that can serve to compound health and wellbeing inequalities. The topics included in the Good Practice Guide series reflect the wider determinants of health and the range of approaches necessary to reduce health inequalities. This first set of three guides is designed, in part, to test their usefulness. There are many other issues and areas where evidence of what works may be needed. It is envisaged that further guides will follow on other issues. All of the guides will be kept under review and amended in light of experience.

Good Practice Guides: Reducing young people's drinking

Actions to tackle health inequalities demand the efforts of government, statutory organisations, and community, voluntary and private sectors. This Good Practice Guide to reducing young people's drinking is one of a series designed to capture information about health inequalities and highlight evidence-based interventions and key actions for improvement across sectors.This resource was contributed by The National Documentation Centre on Drug Use.
