Avaliação da efectividade de uma intervenção em psiquiatria de ligação na doença coronária aguda

RESUMO: Várias intervenções psiquiátricas e psicossociais têm demonstrado ser eficazes na redução da depressão e da ansiedade em indivíduos que sofreram um acidente coronário agudo. A possiblidade de modificarem a evolução da doença coronária e de reduzirem a mortalidade cardíaca continua, no entanto, por comprovar. Este estudo teve como principal objectivo avaliar a efectividade de uma intervenção de Psiquiatria de Ligação (PL) em doentes com cardiopatia isquémica aguda. Métodos: um grupo inicial de 129 doentes consecutivos, internados por Enfarte Agudo do Miocárdio (EAM) ou Angina Instável, numa unidade de cuidados intensivos foi avaliado com a Hospital Anxiety e Depression Scale (HADS). Os doentes que apresentaram uma pontuação ≥8 nas subescalas da Depressão ou da Ansiedade (n=72) foram aleatoriamente distribuídos por grupo de intervenção (GI) (n=37) e grupo de controlo (GC) (n=35). O GI foi sujeito a uma intervenção de PL, realizada durante o período hospitalar, que se iniciou nos primeiros dias de internamento e consistiu em pelo menos 3 sessões individuais (incluindo avaliação psiquiátrica, psicoterapia de suporte, intervenção psicoeducativa e medicação, quando necessário). A sessão pré-alta envolveu o cônjuge e abordou a modificação de comportamentos de risco, a adesão terapêutica e o regresso ao trabalho. O GC recebeu os cuidados habituais da unidade de internamento. Todos os doentes completaram uma entrevista inicial para avaliação do estado cognitivo (Mini Mental State Examination – MMSE), do ajustamento social (Social Problems Questionnaire – SPQ) e de aspectos sociodemográfi cos e clínicos. Os doentes foram reavaliados antes da alta, aos 45 dias, 3 e 6 meses com a HADS, o SPQ e ainda com o Nottingham Health Profi le (NHP) para avaliação da qualidade de vida. No follow-up de 6 meses foi colhida informação sobre sobrevivência, número e duração de reinternamentos, número de dias de baixa e regresso ao trabalho. Resultados: na amostra de 129 doentes avaliados no início do internamento, 20,9% apresentavam níveis de depressão ≥8 na subescala da Depressão (HADS), 53,5% níveis de ansiedade ≥8 na subescala da Ansiedade (HADS) e 9,3% perturbações cognitivas (MMSE). A avaliação longitudinal desta amostra mostrou que os níveis de depressão, inicialmente baixos, aumentaram nos 45 dias após o internamento, para depois diminuírem até ao fi nal do follow-up. Os níveis de ansiedade, que eram inicialmente altos, aumentaram nos 45 dias seguintes e antiveram- se estáveis, mas altos, até ao fi m do estudo. O GI apresentou uma pontuação média na subescala da depressão signifi cativamente inferior à do GC no follow-up de 6 meses (5,8±4,1 no GI vs. 7,9±4,3 no GC, p=0,04). O número de doentes deprimidos foi signifi cativamente menor no GI nas avaliações realizadas aos 3 meses (11 vs. 18 no GC, p=0,04) e aos 6 meses (12 vs. 18 no GC, p= 0,05). O mesmo aconteceu com o número de doentes ansiosos aos 3 meses (15 no GI vs. 23 no GC, p=0,01). As dimensões do NHP “Isolamento social” aos 45 dias e “Reacção emocional” aos 45 dias e aos 3 meses, bem como a qualidade de vida geral (NHP 2ª parte) aos 3 meses, mostraram melhoria signifi cativa no grupo de intervenção. Embora a intervenção tenha reduzido o nível médio da ansiedade nas várias avaliações após a alta, esta redução não atingiu signifi cância estatística. A intervenção realizada não teve impacto na mortalidade ou nas variáveis relacionadas com a evolução da doença cardíaca no período do follow-up. Conclusões: Os resultados do presente estudo mostram a alta prevalência de depressão e de ansiedade após um acidente coronário agudo e a manutenção de níveis altos de ansiedade nos 6 meses seguintes. Os resultados comprovam também a efectividade de uma intervenção em PL no tratamento da depressão e da ansiedade em doentes que sofreram um acidente coronário agudo. Estes resultados apontam para a necessidade de desenvolvimento de programas de PL para este tipo de doentes, tanto no hospital geral como nos cuidados de saúde primários. Sugerem ainda a necessidade de desenvolvimento de investigação que permita estabelecer o impacto específi co dos diversos tipos de intervenção, assim como compreender os mecanismos subjacentes à associação da depressão e da ansiedade com a doença coronária.----------ABSTRACT:Different types of psychiatric and psychochosocial interventions have proven effi cacy in decreasing anxiety and depression in coronary heart disease. There is, however, an ongoing discussion about the impact these interventions may have on the clinical outcome and on cardiac mortality. The main objective of the current study was to evaluate the effectiveness of a consultation liaison psychiatry (CL) intervention on a group of patients admitted with Myocardial Infarction or Unstable Angina, to a Coronary Care Unit. Methods: The study had a prospective, randomised, controlled design, with a 6-month follow-up. One hundred and twenty-nine consecutive patients were assessed during the first 48 hours of admission with the Hospital Anxiety and Depression Scale (HADS). Those with a score of ≥8 on the Depression or the Anxiety subscales (n=72) were randomly allocated to intervention (n=37) and usual care (n=35). The CL intervention, started during the fi rst days of admission, had a minimum of 3 (60 minutes) sessions, and included a psychiatric evaluation, supportive psychotherapy, a psychoeducational intervention, when necessary, psychotropic drugs. The last session, shortly before discharge, included the spouse and was focused on compliance, modifi cation of behavioral risk factors, and possible diffi culties upon returning to work. Cognitive status (Mini-Mental State Examination - MMSE), social adjustment (Social Problems Questionnaire - SPQ), and demographic and clinical characteristics were also assessed at baseline. Patients were reassessed before discharge, and at 45 days, 3 and 6 months after admission with HADS, SPQ, and with Nottingham Health Profile (NHP) for quality of life. Survival, number of readmissions and days of readmission, number of sickleave days and return to work were assessed at six months. Results: The initial sample of 129 patients, presented a 20.9% prevalence of depressive symptoms, 53.5% of anxiety symptoms, and 9.3% of cognitive disorders. The longitudinal evaluation of this sample showed that the initially low levels of depression were increased 45 days later, and slowlly decreased afterwards till the 6-month follow-up. Initially high anxiety levels, somewhat decreased before discharge, had increased 45 days later, and stayed stable and high till the end of the study. The intervention group showed a signifi cantly lower depression mean score at 6 months (5.8±4.1 vs. 7.9±4.3 in the controls, p=0.04). The number of patients considered depressed was lower in the intervention group at 3(11 vs. 18 controls, p=0.04) and 6 months (12vs. 18 controls, p=0,05). The number of anxious patients was also lower in the intervention.

Avaliação epidemiológica dos internamentos através de um serviço de urgência de segunda linha (SII)

RESUMO: Introdução: A Comissão Nacional para a reestruturação dos Serviços de Saúde Mental em 2004, fez uma proposta de âmbito regional, ao nível da região de Saúde do Norte, levando a uma alteração da rede de referenciação hospitalar dos internamentos em psiquiatria. Métodos: Realizou-se um estudo epidemiológico longitudinal para avaliar factores preditivos de internamento através de um serviço de Urgência de Segunda Linha (SII), que de algum modo reflectisse o funcionamento dos serviços de internamento na região de Saúde do Norte, ao longo de 12 anos, nomeadamente relacionando com factores organizacionais contemplados no Plano Nacional de Saúde Mental e na reorganização da rede de referenciação hospitalar. Resultados: Durante os 12 anos do estudo, verificou-se um aumento estatisticamente significativo do número e duração de internamentos através do SII, com ponto de partida no ano 2008-2009, e de novo a partir do ano 2010-2011 (nº de internamentos), para o qual contribuiu a alteração da rede hospitalar na região de saúde do Norte, nomeadamente pelo facto do HMLemos, assumir a responsabilidade de novo, dos internamentos das áreas de Famalicão, Gondomar e Santa Maria da Feira. Em relação ao número de internamentos, e na análise exploratória, encontramos nas áreas hospitalares fora da área de influência do HMLemos, uma contribuição positiva significativa para o aumento do nº de internamentos ao longo dos anos com os Dx (290, 296, 297, 291, 309). Em relação à área do HMLemos restrita (PVC, STT, Matosinhos, Porto Ocidental), de referir a contribuição positiva significativa dos Dx 309 e 301, para o aumento do número de internamentos ao longo do tempo, sendo que a prevalência maior se mantém relacionada às Psicoses (Dx 295, 296 e 297). Não se concluiu por uma contribuição estatisticamente significativa ( positiva ou negativa), das variáveis independentes idade, sexo ou natureza do internamento em relação à variável dependente ( duração de internamentos/ano). Em relação á variável dependente (nº de internamentos/ano), relativamente aos doentes fora de área de influência do HMLemos, concluiu-se uma contribuição positiva estatisticamente significativa da variável independente idade. Conclusões: Através da análise exploratória foi possível perceber o esforço realizado pelos hospitais no sentido de melhorar a equidade e acessibilidade dos doentes à Saúde Mental, a par da reorganização da rede hospitalar. De destacar a necessidade de encontrar alternativas às situações de internamento, com menos critérios de gravidade diagnóstica, nomeadamente reforçar a importância da criação de consultas de crises nos respectivos Hospitais de Dia dos DPSM.----------------ABSTRACT:Introduction : The National Commission for the restructuring of mental health services in 2004 , has proposed at a regional level ( North Health Region), a change in the network of hospital referrals of admissions in psychiatry. Methods: We conducted a longitudinal epidemiological study to assess predictors of hospitalization through a Second Line Emergency Service ( SII) , that somehow reflect the operation of inpatient services in North Health Region, over 12 years, particularly relating to organizational factors included in the National Mental Health Plan and reorganization of the hospital referral network. Results: During the period of the study, there was a statistically significant increase in the number and duration of hospitalizations through the SII, with starting point in the year 2008-2009 and again from 2010-2011 (number of admissions) , for which counted the change of the hospital network referral in Northern health region , in particular because Hospital Magalhães Lemos (HMLemos) , took the new responsibility of admissions from areas of Famalicão, Gondomar and Santa Maria da Feira . Regarding the number of hospitalizations, in the exploratory analysis , we found in hospital areas outside the area of influence of HMLemos , a significant positive contribution to the increase in number of admissions over the years with Diagnosis of 290, 296, 297, 291 , 309 in the ICD-9. With respect to the restricted area of HMLemos (PVC, STT , Porto Ocidental and Matosinhos) , we found a significant positive contribution of Diagnosis 309 and 301, to increase the number of hospitalizations over time, with higher prevalence rates remaining the psychoses ( Dx 295, 296 and 297 ) . Did not conclude for any statistically significant contribution (positive or negative) of the independent variables age, sex and nature of admission to the dependent variable (duration of hospitalization / year). In relation to the dependent variable (number of admissions / year) relative to patients outside the area of influence of HMLemos, it was found a statistically significant positive contribution of the independent variable age . Conclusions: Through the exploratory analysis, it was possible to see the efforts made by hospitals to improve the accessibility of patients to Mental Health, throughout the hospital network reorganization. Its important to highlight the need to find alternatives to inpatient admissions in those with less gravity diagnostic criteria, reinforcing the importance of creating specific crisis consultations in Day Hospital regime.

Assessing cost-effectiveness - Mental health: introduction to the study and methods

Objective: The Assessing Cost-Effectiveness - Mental Health (ACE-MH) study aims to assess from a health sector perspective, whether there are options for change that could improve the effectiveness and efficiency of Australia's current mental health services by directing available resources toward 'best practice' cost-effective services. Method: The use of standardized evaluation methods addresses the reservations expressed by many economists about the simplistic use of League Tables based on economic studies confounded by differences in methods, context and setting. The cost-effectiveness ratio for each intervention is calculated using economic and epidemiological data. This includes systematic reviews and randomised controlled trials for efficacy, the Australian Surveys of Mental Health and Wellbeing for current practice and a combination of trials and longitudinal studies for adherence. The cost-effectiveness ratios are presented as cost (A$) per disability-adjusted life year (DALY) saved with a 95% uncertainty interval based on Monte Carlo simulation modelling. An assessment of interventions on 'second filter' criteria ('equity', 'strength of evidence', 'feasibility' and 'acceptability to stakeholders') allows broader concepts of 'benefit' to be taken into account, as well as factors that might influence policy judgements in addition to cost-effectiveness ratios. Conclusions: The main limitation of the study is in the translation of the effect size from trials into a change in the DALY disability weight, which required the use of newly developed methods. While comparisons within disorders are valid, comparisons across disorders should be made with caution. A series of articles is planned to present the results.

Child psychiatry takes to the streets: A developmental partnership between a university institute and children and adolescents from the streets of Sao Paulo, Brazil

Objective: High levels of domestic violence, mental illness, and alienation from authorities are associated with high incidence of children/adolescents living on the streets in low and middle income countries. The Equilibrium Project (Programa Equilibrio) was created to facilitate social reintegration through a virtual partnership between an academic psychiatric institute and highly vulnerable children and adolescents living on the streets, in group shelter with supervision, and in other high risk situations. Methods: Descriptive presentation of qualitative data and analysis of preliminary empirical data collected over a 24-month period. Results: Dialogue between academic professionals, street children, and city officials shaped The Equilibrium Project over the last 2 years. The program has progressively moved from a professional clinic setting to a community-based but protected activity center with recreational and professional services and an emphasis on linkage with social service agencies, city government and law enforcement officials in an academic research context. A total of 351 patients have been served of whom virtually all were neglected by their parents, 58.4% report physical or sexual abuse, 88.89% have been diagnosed with a psychiatric disorder, 40.4% drug use. After 2 years of operation, 63.5% (n = 223) successfully completed or continue in treatment and 34.8% (n = 122) were reunited with their families. Conclusions and Practice implications: Program development guided by consumer input led to a successful program offering professional services in a protected community setting that facilitates social reintegration by providing ""go between"" services integrating relationships between alienated consumers and formal psychiatric, pediatric, social service, and criminal justice systems.

Assessment of a consultation-liaison psychiatry and psychology health care program

OBJECTIVE: To investigate the relevance of subjective criteria adopted by a psychiatry and psychology consultation-liaison service, and their suitability in the evaluation of case registries and objective results. METHODS: Semi-structured interviews were conducted and all supervisors of the university hospital service were interviewed. Routinely collected case registries were also reviewed. Standardized assessment with content analysis for each category was carried out. RESULTS: The results showed distortions in the adopted service focus (doctor-patient relationship) and consultant requests. This focus is more on consulting physician-oriented interventions than on patients. DISCUSSION: Evaluation of the relevance of service criteria could help promoting quality assessment of the services provided, mainly when objective criteria have not yet been established to assure their suitability.

Mental health and psychiatry research in Brazil: scientific production from 1999 to 2003

OBJECTIVE: To assess the extent of mental health scientific production in Brazil from 1999 to 2003, and to identify the nature of the publications generated, their sources of finance and the ways of publicly disseminating the research findings. METHODS: Searches for publications were conducted in the Medline and PsychInfo databases for the period 1999-2003. A semi-structured questionnaire developed by an international team was applied to 626 mental health researchers, covering each interviewee's educational background, research experience, access to funding sources, public impact and research priorities. The sample was composed by 626 mental health researchers identified from 792 publications indexed on Medline and PsychInfo databases for the period above, and from a list of reviewers of Revista Brasileira de Psiquiatria. RESULTS: In Brazil, 792 publications were produced by 525 authors between 1999 and 2003 (441 indexed in Medline and 398 in the ISI database). The main topics were: depression (29.1%), substance misuse (14.6%), psychoses (10%), childhood disorders (7%) and dementia (6.7%). Among the 626 Brazilian mental health researchers, 329 answered the questionnaire. CONCLUSIONS: There were steadily increasing numbers of Brazilian articles on mental health published in foreign journals from 1999 to 2003: the number of articles in Medline tripled and it doubled in the ISI database. The content of these articles corresponded to the priorities within mental health, but there is a need for better interlinking between researchers and mental health policymakers.

Performing masculinity, influencing health: a qualitative mixed-methods study of young Spanish men

Background: The literature shows how gender mandates contribute to differences in exposure and vulnerability to certain health risk factors. This paper presents the results of a study developed in the south of Spain, where research aimed at understanding men from a gender perspective is still limited. Objective: The aim of this paper is to explore the lay perceptions and meanings ascribed to the idea of masculinity, identifying ways in which gender displays are related to health. Design: The study is based on a mixed-methods data collection strategy typical of qualitative research. We performed a qualitative content analysis focused on manifest and latent content. Results: Our analysis showed that the relationship between masculinity and health was mainly defined with regard to behavioural explanations with an evident performative meaning. With regard to issues such as driving, the use of recreational drugs, aggressive behaviour, sexuality, and body image, important connections were established between manhood acts and health outcomes. Different ways of understanding and performing the male identity also emerged from the results. The findings revealed the implications of these aspects in the processes of change in the identity codes of men and women. Conclusions: The study provides insights into how the category ‘man’ is highly dependent on collective practices and performative acts. Consideration of how males perform manhood acts might be required in guidance on the development of programmes and policies aimed at addressing gender inequalities in health in a particular local context.

Hierarchical linear models in Psychiatry: A bibliometric study

Development of research methods requires a systematic review of their status. This study focuses on the use of Hierarchical Linear Modeling methods in psychiatric research. Evaluation includes 207 documents published until 2007, included and indexed in the ISI Web of Knowledge databases; analyses focuses on the 194 articles in the sample. Bibliometric methods are used to describe the publications patterns. Results indicate a growing interest in applying the models and an establishment of methods after 2000. Both Lotka"s and Bradford"s distributions are adjusted to the data.

Clinical usefulness of the Screen for Cognitive Impairment in Psychiatry (SCIP-S) scale in patients with type I bipolar disorder

Background: The relevance of persistent cognitive deficits to the pathogenesis and prognosis of bipolar disorders (BD) is understudied, and its translation into clinical practice has been limited by the absence of brief methods assessing cognitive status in Psychiatry. This investigation assessed the psychometric properties of the Spanish version of the Screen for Cognitive Impairment in Psychiatry (SCIP-S) for the detection of cognitive impairment in BD. Methods: After short training, psychiatrists at 40 outpatient clinics administered the SCIP three times over two weeks to a total of 76 consecutive type I BD admissions. Experienced psychologists also administered a comprehensive battery of standard neuropsychological instruments to clinical sample and 45 healthy control subjects. Results: Feasibility was supported by a brief administration time (approximately 15 minutes) and minimal scoring errors. The reliability of the SCIP was confirmed by good equivalence of forms, acceptable stability (ICC range 0.59 to 0.87) and adequate internal consistency (Chronbach's alpha of 0.74). Construct validity was granted by extraction of a single factor (accounting 52% of the variance), acceptable correlations with conventional neuropsychological instruments, and a clear differentiation between bipolar I and normal samples. Efficiency was also provided by the adequate sensitivity and specificity. Limitations: The sample size is not very large. The SCIP and the neurocognitive battery do not cover all potentially relevant cognitive domains. Also, sensitivity to change remains unexplored. Conclusion: With minimal training, physicians obtained a reliable and valid estimate of cognitive impairment in approximately 15 minutes from an application of the SCIP to type I BD patients.

Clinical features of panic patients sensitive to hyperventilation or breath-holding methods for inducing panic attacks

Our aim was to compare the clinical features of panic disorder (PD) patients sensitive to hyperventilation or breath-holding methods of inducing panic attacks. Eighty-five PD patients were submitted to both a hyperventilation challenge test and a breath-holding test. They were asked to hyperventilate (30 breaths/min) for 4 min and a week later to hold their breath for as long as possible, four times with a 2-min interval. Anxiety scales were applied before and after the tests. We selected the patients who responded with a panic attack to just one of the tests, i.e., those who had a panic attack after hyperventilating (HPA, N = 24, 16 females, 8 males, mean age ± SD = 38.5 ± 12.7 years) and those who had a panic attack after breath holding (BHPA, N = 20, 11 females, 9 males, mean age ± SD = 42.1 ± 10.6 years). Both groups had similar (chi² = 1.28, d.f. = 1, P = 0.672) respiratory symptoms (fear of dying, chest/pain disconfort, shortness of breath, paresthesias, and feelings of choking) during a panic attack. The criteria of Briggs et al. [British Journal of Psychiatry, 1993; 163: 201-209] for respiratory PD subtype were fulfilled by 18 (75.0%) HPA patients and by 14 (70.0%) BHPA patients. The HPA group had a later onset of the disease compared to BHPA patients (37.9 ± 11.0 vs 21.3 ± 12.9 years old, Mann-Whitney, P < 0.001), and had a higher family prevalence of PD (70.8 vs 25.0%, chi² = 19.65, d.f. = 1, P = 0.041). Our data suggest that these two groups - HPA and BHPA patients - may be specific subtypes of PD.

Transcranial direct current stimulation and repetitive transcranial magnetic stimulation in consultation-liaison psychiatry

Patients with clinical diseases often present psychiatric conditions whose pharmacological treatment is hampered due to hazardous interactions with the clinical treatment and/or disease. This is particularly relevant for major depressive disorder, the most common psychiatric disorder in the general hospital. In this context, nonpharmacological interventions could be useful therapies; and, among those, noninvasive brain stimulation (NIBS) might be an interesting option. The main methods of NIBS are repetitive transcranial magnetic stimulation (rTMS), which was recently approved as a nonresearch treatment for some psychiatric conditions, and transcranial direct current stimulation (tDCS), a technique that is currently limited to research scenarios but has shown promising results. Therefore, our aim was to review the main medical conditions associated with high depression rates, the main obstacles for depression treatment, and whether these therapies could be a useful intervention for such conditions. We found that depression is an important and prevalent comorbidity in a variety of diseases such as epilepsy, stroke, Parkinson's disease, myocardial infarction, cancer, and in other conditions such as pregnancy and in patients without enteral access. We found that treatment of depression is often suboptimal within the above contexts and that rTMS and tDCS therapies have been insufficiently appraised. We discuss whether rTMS and tDCS could have a significant impact in treating depression that develops within a clinical context, considering its unique characteristics such as the absence of pharmacological interactions, the use of a nonenteral route, and as an augmentation therapy for antidepressants.
