Clinicians' attitudes to clinical practice guidelines

To the Editor: In their systematic review of clinicians' attitudes to clinical practice guidelines, Farquhar et al1 found that, although healthcare providers reported high satisfaction with guidelines, a significant number also expressed concerns about their practicality, their role in cost-cutting and their potential for increasing litigation. The review, however, did not address other potentially significant concerns of clinicians regarding the perceived validity of guidelines and the influence of external agencies (such as the pharmaceutical industry) on treatment recommendations.

Managing urinary incontinence across the lifespan

In the 1996 baseline surveys of the Australian Longitudinal Study of Women's Health (ALSWH), 36.1% of mid-age women (45-50) and 35% of older women (70-75) reported leaking urine. This study aimed to investigate (a) the range of self-management strategies used to deal with urinary incontinence (UI); (b) the reasons why many women who report leaking urine do not seek help for UI; and (c) the types of health professionals consulted and treatment provided, and perceptions of satisfaction with these, among a sample of women in each age group who reported leaking urine often' at baseline. Five hundred participants were randomly selected from women in each of the mid-age and older cohorts of the ALSWH who had reported leaking urine often in a previous survey. Details about UI (frequency, severity, and situations), self-management behaviors and help-seeking for UI, types of health professional consulted, recommended treatment for the problem, and satisfaction with the service provided by health care professionals and the outcomes of recommended treatments were sought through a self-report mailed follow-up survey. Most respondents had leaked urine in the last month (94% and 91% of mid-age and older women, respectively), and 72.2% and 73. 1% of mid-aged and older women, respectively, had sought help or advice about their UI. In both age groups, the likelihood of having sought help significantly increased with severity of incontinence. The most common reasons for not seeking help were that the women felt they could manage the problem themselves or they did not consider it to be a problem.. Many women in both cohorts had employed avoidance techniques in an attempt to prevent leaking urine, including reducing their liquid consumption, going to the toilet just in case, and rushing to the toilet the minute they felt the need to. Strategies are needed to inform women who experience UI of more effective management techniques and the possible health risks associated with commonly used avoidance behaviors. There may be a need to better publicize existing incontinence services and improve access to these services for women of all ages.

Efeito da geometria dos dentes da serra de fita na produção de madeira serrada de eucalipto

O objetivo deste trabalho foi determinar o efeito dos parâmetros que compõem os dentes de serra de fita na produção e qualidade da madeira serrada de eucalipto. Analisou-se o efeito de dois passos de dentes (57,15 mm e passo variado: 50,8 - 50,8 - 50,39 - 50,71 - 60,03 - 60,35 mm), de dois ângulos de ataque (26 e 270) e de duas alturas (22 e 25,4 mm) em duas classes diamétricas (25 a 34 cm e 35 e 47 cm) de clones de híbridos Eucalyptus grandis x Eucalyptus urophylla com 15 anos de idade. Não houve ganho de qualidade quando se trabalhou com passo variado. As lâminas de serra que possuíam ângulo de ataque de 270 e passo único tanto com altura do dente de 22 mm quanto com 25,4 mm geraram desvios acima da espessura-meta. A menor variação em torno da espessura-meta foi obtida quando se utilizaram lâminas de serra de ângulo de ataque de 270 e altura do dente de 25,4 mm. O maior desvio ocorreu quando o desdobro foi efetuado com passo variado e ângulo de ataque de 260. A utilização de passo variado, de modo geral, foi o que apresentou maiores desvios na espessura das tábuas em relação à espessura desejada.

Satisfação com a prótese auditiva na vida diária em usuários do Sistema de Saúde do Exército

O objetivo deste estudo foi investigar o nível de satisfação com a prótese auditiva na vida diária em usuários do Sistema de Saúde do Exército e fatores associados. Foram selecionados adultos e idosos, usuários do convênio de saúde da 3ª Região Militar, que adquiriram prótese auditiva entre os anos de 1998 e 2003, para responderem ao questionário SADL (Satisfaction with Amplification in Daily Life). Foram excluídos do estudo indivíduos com idade inferior a 18 anos; que adquiriram a prótese auditiva há menos de 6 semanas; com grave limitação da capacidade de compreensão e expressão; e que não concordaram em participar da pesquisa. Os resultados mostraram que os pacientes estavam consideravelmente satisfeitos com o uso da prótese auditiva. Houve menor satisfação na subescala fatores negativos do SADL, especialmente em relação ao uso do telefone. Tiveram associação com a satisfação fatores ligados à pessoa e, principalmente, à reabilitação auditiva. Os dados mostraram que, além da seleção da prótese tecnicamente mais adequada, tem fundamental importância a implantação de programas de reabilitação auditiva, com experiência domiciliar, orientações e aconselhamento, buscando que o paciente tenha expectativas realistas.

O planejamento econômico no Brasil: considerações críticas

In the past thirty years, a series of plans have been developed by successive Brazilian governments in a continuing effort to maximize the nation's resources for economic and social growth. This planning history has been quantitatively rich but qualitatively poor. The disjunction has stimulated Professor Mello e Souza to address himself to the problem of national planning and to offer some criticisms of Brazilian planning experience. Though political instability has obviously been a factor promoting discontinuity, his criticisms are aimed at the attitudes and strategic concepts which have sought to link planning to national goals and administration. He criticizes the fascination with techniques and plans to the exclusion of proper diagnosis of the socio-political reality, developing instruments to coordinate and carry out objectives, and creating an administrative structure centralized enough to make national decisions and decentralized enough to perform on the basis of those decisions. Thus, fixed, quantified objectives abound while the problem of functioning mechanisms for the coordinated, rational use of resources has been left unattended. Although his interest and criticism are focused on the process and experience of national planning, he recognized variation in the level and results of Brazilian planning. National plans have failed due to faulty conception of the function of planning. Sectorial plans, save in the sector of the petroleum industry under government responsibility, ha e not succeeded in overcoming the problems of formulation and execution thereby repeating old technical errors. Planning for the private sector has a somewhat brighter history due to the use of Grupos Executivos which has enabled the planning process to transcend the formalism and tradition-bound attitudes of the regular bureaucracy. Regional planning offers two relatively successful experiences, Sudene and the strategy of the regionally oriented autarchy. Thus, planning history in Brazil is not entirely black but a certain shade of grey. The major part of the article, however, is devoted to a descriptive analysis of the national planning experience. The plans included in this analysis are: The Works and Equipment Plan (POE); The Health, Food, Transportation and Energy Plan (Salte); The Program of Goals; The Trienal Plan of Economic and Social Development; and the Plan of Governmental Economic Action (Paeg). Using these five plans for his historical experience the author sets out a series of errors of formulation and execution by which he analyzes that experience. With respect to formulation, he speaks of a lack of elaboration of programs and projects, of coordination among diverse goals, and of provision of qualified staff and techniques. He mentions the absence of the definition of resources necessary to the financing of the plan and the inadequate quantification of sectorial and national goals due to the lack of reliable statistical information. Finally, he notes the failure to coordinate the annual budget with the multi-year plans. He sees the problems of execution as beginning in the absence of coordination between the various sectors of the public administration, the failure to develop an operative system of decentralization, the absence of any system of financial and fiscal control over execution, the difficulties imposed by the system of public accounting, and the absence of an adequate program of allocation for the liberation of resources. He ends by pointing to the failure to develop and use an integrated system of political economic tools in a mode compatible with the objective of the plans. The body of the article analyzes national planning experience in Brazil using these lists of errors as rough model of criticism. Several conclusions emerge from this analysis with regard to planning in Brazil and in developing countries, in general. Plans have generally been of little avail in Brazil because of the lack of a continuous, bureaucratized (in the Weberian sense) planning organization set in an instrumentally suitable administrative structure and based on thorough diagnoses of socio-economic conditions and problems. Plans have become the justification for planning. Planning has come to be conceived as a rational method of orienting the process of decisions through the establishment of a precise and quantified relation between means and ends. But this conception has led to a planning history rimmed with frustration, and failure, because of its rigidity in the face of flexible and changing reality. Rather, he suggests a conception of planning which understands it "as a rational process of formulating decisions about the policy, economy, and society whose only demand is that of managing the instrumentarium in a harmonious and integrated form in order to reach explicit, but not quantified ends". He calls this "planning without plans": the establishment of broad-scale tendencies through diagnosis whose implementation is carried out through an adjustable, coherent instrumentarium of political-economic tools. Administration according to a plan of multiple, integrated goals is a sound procedure if the nation's administrative machinery contains the technical development needed to control the multiple variables linked to any situation of socio-economic change. Brazil does not possess this level of refinement and any strategy of planning relevant to its problems must recognize this. The reforms which have been attempted fail to make this recognition as is true of the conception of planning informing the Brazilian experience. Therefore, unworkable plans, ill-diagnosed with little or no supportive instrumentarium or flexibility have been Brazil's legacy. This legacy seems likely to continue until the conception of planning comes to live in the reality of Brazil.

A influência do controlo do acesso à internet na satisfação com o trabalho

RESUMO: A presente investigação incide no estudo da influência das dimensões do controlo do acesso à Internet, propostas por Hackman e Oldham (1975), e das facetas da satisfação com o trabalho, propostas por Spector (1985) num contexto organizacional. Os dados foram obtidos através da aplicação de três escalas avaliativas: o "Job Diagnostic Survey" (JDS), o "Job Satisfaction Survey" (JSS), e uma escala criada para avaliar as dimensões do controlo do acesso à Internet. O estudo incidiu numa amostra de conveniência, constituída por 135 colaboradores pertencentes a três organizações. Os resultados obtidos demonstraram que apenas três dimensões revelaram relações de antecedência com as dimensões da satisfação com o trabalho: no bloqueio a páginas e aplicações foram identificadas relações de antecedência com a da satisfação com os benefícios adicionais e com a promoção. Quanto à voz nas políticas da organização foram identificadas relações com a satisfação com os colegas, e com a natureza do trabalho. E na legislação foram identificadas relações com a satisfação com as recompensas contingenciais, com as condições operantes e com a comunicação. Os resultados levaram à não confirmação do modelo em análise, por não estar em linha com o quadro teórico estabelecido. Foram discutidas algumas das implicações dos resultados obtidos. ABSTRACT: The current research focus in the study of influence between the Internet Access control dimensions, proposed in this study, and the global Job satisfaction, proposed by Hackman e Oldham (1975) and the job satisfaction facets proposed by Spector (1985) in a organizationsl context. The data eas obtained through the application of three scales: num contexto organizacional. "Job Diagnostic Survey" (JDS), the "Job Satisfaction Survey" (JSS),and a scale that was created to evaluate the internet Access control. The study focused on a convenience sample, constituted by 135 participants from three organizations. The results show that only three dimensions revealed to have an antecedent relationship with the job satisfaction dimensions: in the websites and applications blocking, it was identified as having an antecedent relationship with the satisfaction with fringe benefits and promotion. Voice in the organizational policies was verified as an antecedent to the dimensions of the satisfaction with the coworkers and with the nature of work. And finally, the legislation was confirmed as an antecedent in the relationship with the dimensions satisfaction with contingent rewards, operating conditions and communication. The results led to the non confirmation of the studied theoretical model. Some of these results implications were discussed.

Are public officials really less satisfied than private sector workers?A comparative study in Brazil

This research aims to compare the public and private sectors with regard to satisfaction at work. We conducted a survey with 670 professionals from both sectors in Brazil. The results of variance analysis confirm previous researches indicating that public officials are less satisfied with their work than private sector workers. However, this result does not repeat when we evaluate the satisfaction dimensions. For instance, public officials reported being more satisfied than private sector workers with regard to social environment and work stability. Unexpectedly, the results suggest that there is no difference between these sectors when we analyze the satisfaction with supervision. Therefore, this article is relevant for Brazilian managers, by offering an empirical research on the distinction between public and private. The article also discusses the theoretical implications, since Brazilian findings do not completely support the international literature.

Variáveis psicológicas e percepção do estado de saúde em indivíduos submetidos a ressincronização cardíaca

A insuficiência cardíaca afecta cerca de 261 mil pessoas em Portugal constituindo um problema de saúde pública. Pretendemos avaliar aspectos associados à recuperação do estado de saúde nesta síndrome, em particular a esperança, o afecto e a felicidade. Recorremos a um estudo longitudinal com 128 indivíduos sintomáticos com má fracção de ejecção do ventrículo esquerdo. Utilizámos um questionário para caracterizar os aspectos sóciodemográficos, clínicos e funcionais, o Kansas City Cardiomiopathy Questionnaire (KCCQ) para avaliar a qualidade de vida, a Subjective Hapiness Scale (SHS) para a felicidade, a HOPE Scale (HOPE) para a esperança e a Positive And Negative Afect Schedule (PANAS) para o afecto. Os questionários de caracterização sócio-demográfica, clínica e funcional, KCCQ e o SHS foram aplicados em três momentos: no internamento, prévio à instituição de terapêutica médica na sua totalidade e ao terceiro e sexto mês após a intervenção médica, na consulta externa. A maioria dos participantes eram homens em classe III da classificação da New York Heart Association com etiologia isquémica. No internamento e antes da terapêutica médica, observámos que a esperança, a felicidade e o afecto se relacionaram com a qualidade de vida, a felicidade e o afecto positivo com a esperança. No período avaliado foram submetidos a: terapia de ressincronização cardíaca (n=52), cardioversor-desfibrilhador implantável (n=44), cirurgia valvular com revascularização do miocárdio (n=14), optimização terapêutica farmacológica (n=10), transplante cardíaco (n=8). Foram significativos os resultados da qualidade de vida, da classificação da New York Heart Association, do exercício físico, da fracção de ejecção do ventrículo esquerdo e das arritmias cardíacas (estrasístoles e taquicardias ventriculares). A felicidade foi preditora da qualidade de vida e da funcionalidade. O afecto negativo foi preditor da satisfação com a insuficiência cardíaca. Concluímos da importância das variáveis positivas a par dos procedimentos médicos no tratamento das pessoas com insuficiência cardíaca. ABSTRACT - Heart failure affects about 261 000 people in Portugal constituting a public health problem. We intend to evaluate aspects of the health recovery in this syndrome, in particular hope, affection and happiness. We used a longitudinal study with 128 symptomatic patients with poor ejection fraction of left ventricle. We used a questionnaire to characterize the socio-demographic, clinical and functional aspects, the Kansas City Cardiomiopathy Questionnaire (KCCQ) to assess the quality of life, the Subjective Happiness Scale (SHS) for happiness, the HOPE Scale (HOPE) for hope and the Positive And Negative Affect Schedule (PANAS) for affection. The questionnaires of sociodemographic, clinical and functional KCCQ and SHS were applied on three occasions: on admission, prior to the execution of medical therapy in its totality and in the third and sixth months after medical intervention in the outpatient. Most of the participants were men in Class III New York Heart Association classification with ischemic etiology. At admission and before medical therapy, we observed that the hope, happiness and affection were related to the quality of life, happiness and positive affect with hope. Over the studied period were submitted to: cardiac resynchronization therapy (n=52), implantable cardioverter-defibrillator (n=44), valvular surgery with coronary artery bypass graft surgery (n=14), optimizing drug therapy (n=10), heart transplant (n=8). The significant results were the quality of life, the New York Heart Association classification, the exercise, the ejection fraction and left ventricular cardiac arrhythmias (ventricular tachycardia and estrasistoles). Happiness was a predictor of quality of life and functionality. The negative affect was a predictor of satisfaction with heart failure. We concluded that the positive variables and the medical procedures were important in treating people with heart failure.

Aspectos psicossociais associados à percepção da dor pós-operatória em indivíduos submetidos a cirurgia coronária

Objectivo: Identificar os factores psicossociais que influenciam a percepção da dor pós-operatória em doentes submetidos a cirurgia de revascularização do miocárdio (CRM). Material e Métodos: Estudo exploratório correlacional de 91 doentes (71 homens e 20 mulheres) submetidos a CRM (pontagem aortocoronária) por esternotomia). A idade média era de 63,8 ± 9,6 anos (entre 39 e 84). Foram utilizados os seguintes instrumentos: Escala Analógica Visual às 24, 48 e 96 horas do pós-operatório; Questionário de Caracterização Demográfica; Mental Health Inventory de 5 itens; Percepção de Saúde Geral (SF-36); Escala de Expectativas de Dor; Escala de Percepção de Apoio; Escala de Expectativas de Auto-eficácia; Satisfação com o tratamento, médicos e enfermeiros (American Pain Society Questionnaire) aplicados às 96 horas após a cirurgia. Resultados: Os doentes que apresentaram expectativas elevadas de dor, percepcionaram maior apoio, apresentaram níveis elevados de auto-eficácia para lidar com a dor ou, se pertenciam ao sexo masculino, sentiram menos dor. De igual modo, os doentes que apresentaram melhor saúde mental, percepcionaram a sua saúde como boa e os doentes que expressaram maior satisfação com o tratamento sentiram menos dor. A dor não foi influenciada pela idade, grau de escolaridade ou pela satisfação com a conduta de médicos e enfermeiros. Conclusão: Após as primeiras 48 horas do pós-operatório, a experiência de dor é influenciada por factores psicossociais, em oarticular pela expectativa de dor, expectativa de auto-eficácia, apoio percebido, percepção da saúde geral, percepção de saúde mental e satisfação com o tratamento para a dor. Perante os resultados, evidencia-se a necessidade de conjugar conhecimentos no sentido de dar respostas mais alargadas e de carácter multidisciplinar no tratamento da dor pós-operatória em CRM devendo, a par de outros aspectos, focar-se na gestão das expectativas dos doentes. ABSTRACT - Objective: To identify the psychological factors that influence post-surgery pain perception in patients undergoing coronary artery bypass graft surgery (CABG). Methods: This was an exploratory correlational study of 91 patients (71 men and 20 women) who underwent CABG (aortocoronary anastomosis) by sternotomy. Mean age was 63.8 ± 9.6 years (between 39 and 84). The following instruments were used: visual analogical scales at 24, 48 and 96 hours of post-surgery; demographic characteristics survey; pain expectations scale; perceived support scale; self-efficacy scale, Mental Inventory (5 items); health perception scale; and satisfaction with treatment, doctors and nurses (American Pain Society questionnaire) at 96 hours after surgery. Results: Patients who had presented high expectations of pain, perceived more support, presented high levels of self-efficacy to deal with pain or were male, felt less pain. Furthermore, patients who presented better mental health, perceived their general health as being good, or expressed greater satisfaction with treatment, felt less pain. Pain was not influenced by age, level of education or satisfaction with doctors and nurses. Conclusion: After the first 48 hours following surgery, the pain experience is influenced by psychosocial factors, in particular by expectation of pain and of self-efficacy, perceived support, perception of general and mental health, and satisfaction with pain treatment. The results confirm the need to bring together different kinds of knowledge for a broad, multidisciplinary approach to postoperative CABG pain treatment, focusing, along with other aspects, on management of patients’ expectations.

Implementação de sistemas da qualidade numa empresa de transporte rodoviário fraccionado de mercadorias: indicadores de competitividade

A certificação deixou de ser “apenas” uma vantagem competitiva para passar a ser um critério seleccionador de empresas diferenciando-as das concorrentes. O conceito de melhoria contínua subjacente à norma ISO 9001 transmite para o mercado a imagem de empresas capazes de satisfazer e superar as exigências dos clientes, direccionando todos os colaboradores para esse objectivo comum. O sector dos Transportes aderiu em força a esta inovação mostrando interesse em melhorar a qualidade do serviço prestado e dos processos. O objectivo deste estudo é contribuir para a avaliação da implementação do Sistema de Gestão da Qualidade (SGQ) ISO 9001:2008 numa empresa de Transportes rodoviários de mercadorias porta a porta (TRMPP) – também designado por Transporte Fraccionado de Mercadorias. Elaborou-se um questionário a clientes construindo-se os indicadores de forma a identificar pontos fortes e pontos fracos no sentido da melhoria contínua da qualidade. Destacam-se a competitividade relativamente às devoluções, grau de satisfação relativamente à competitividade geral, classificação do serviço prestado pelos motoristas/ ajudantes. Conclui-se que a principal razão que levou a empresa a implementar o SGQ foi a necessidade de responder a alguns requisitos nomeadamente concursos públicos onde implicitamente existem indicadores de satisfação dos clientes e outros de melhoria da qualidade do produto/serviço. Durante o processo de implementação do SGQ, surgiram dificuldades relacionadas essencialmente com o tempo necessário para tratar de burocracias e com os custos da Qualidade. Concluiu-se ainda que a Gestão de topo, os Directores e os Chefes de Secção, são os principais responsáveis pela detecção e correcção de não conformidades, bem como a empresa que implementou novos métodos de motivação dos colaboradores, destacando a formação e a comunicação.

Medição da satisfação profissional dos técnicos de farmácia e farmacêuticos do norte de Portugal

Vários trabalhos têm associado a Satisfação Profissional (SP) a variáveis como a produtividade, o absentismo e o turnover (McPherson, Davies, Bewick, & Bhudia, 1999, citado em Ferguson, Ashcroft, & Hassell, 2011; Mott, 2000; Judge, Thoresen, Bono, & Patton, 2001) indicando ser importante o estudo da problemática nos Técnicos de Farmácia e Farmacêuticos, uma vez que pode condicionar a prestação de cuidados de saúde. Pretendeu-se medir e comparar a SP entre Técnicos de Farmácia e Farmacêuticos e entre Farmácia Hospitalar e de Oficina do Norte de Portugal. Verificou-se a relação entre a SP e: idade, género, grau de formação na área da Farmácia, experiência profissional (em anos) e experiência profissional no local de trabalho (em anos). Utilizou-se a escala Job Satisfaction Survey (JSS) (Spector, 1985), tendo sido adaptada e validada para o contexto. A JSS e subescalas revelaram correlação de carácter forte com a escala e subescalas da Minnesota Satisfaction Questionnaire-Short version (MSQ) de Weiss, Dawis, England, & Lofquist (1967). Contudo, apenas foi identificada validade convergente entre algumas das subescalas da JSS com a MSQ e respectivas subescalas, o que sugere que ambas (JSS e MSQ) medem construtos que estão intimamente associados mas não medem exactamente o mesmo. A amostra é constituída por 291 profissionais que responderam ao instrumento entre Março de 2010 e Abril de 2011. Foram encontrados níveis de SP positivos excepto para a Satisfação com o superior hierárquico directo (média inferior a 3) e Satisfação com procedimentos de trabalho e comunicação na organização (valor ambivalente entre 3 e 4). Diferenças foram encontradas entre Farmácia de Oficina e Hospitalar e entre Técnicos de Farmácia e Farmacêuticos, sendo revelados níveis de Satisfação mais elevados para os Técnicos de Farmácia. Também foram encontradas diferenças para o género (SP global e subescalas) e para o nível de formação em Farmácia (algumas subescalas). A idade, a experiência profissional e a experiência profissional no local de trabalho revelaram associação positiva com a SP global e com algumas das subescalas. A lacuna existente neste tipo de estudos para os profissionais de saúde e nomeadamente dos Técnicos de Farmácia e Farmacêuticos em Portugal tornam este estudo relevante e inovador, lançando novas pistas e direccionando novas investigações.

Can varying the number of teams in a shift schedule constitute a preventive strategy?

OBJECTIVE: The study examines the implications for shiftworkers of applying different numbers of teams in the organization of shiftwork. METHODS: The participating operators came from five different companies applying continuous shift rotation systems. The companies shared the same product organization and a common corporate culture belonging to the same multinational company. Each company had a shift system consisting of four, five or six teams, with the proportion of shifts outside day work decreasing as the number of teams increased. Questionnaire and documentary data were used as data sources. RESULTS: Operators in systems with additional teams had more daywork but also more irregular working hours due to both overtime and schedule changes. Operators using six teams used fewer social compensation strategies. Operators in four teams were most satisfied with their work hours. Satisfaction with the time available for various social activities outside work varied inconsistently between the groups. CONCLUSIONS: In rotating systems the application of more teams reduces the number of shifts outside day work. This apparent improvement for shiftworkers was counteracted by a concomitant irregularity produced by greater organizational requirements for flexibility. The balance of this interaction was found to have a critical impact on employees.

Smart offices and intelligent decision rooms

Nowadays computing technology research is focused on the development of Smart Environments. Following that line of thought several Smart Rooms projects were developed and their appliances are very diversified. The appliances include projects in the context of workplace or everyday living, entertainment, play and education. These appliances envisage to acquire and apply knowledge about the environment state in order to reason about it so as to define a desired state for its inhabitants and perform adaptation adaptation to these desires and therefore improving their involvement and satisfaction with that environment.

Modeling Allee Effect from Beta(p, 2) Densities

In this work we develop and investigate generalized populational growth models, adjusted from Beta(p, 2) densities, with Allee effect. The use of a positive parameter leads the presented generalization, which yields some more flexible models with variable extinction rates. An Allee limit is incorporated so that the models under study have strong Allee effect.
