Abstract
A pesquisa epidemiológica na área de serviços de saúde envolve geralmente a experimentação da eficácia de novos programas ou estratégias e a avaliação da qualidade dos serviços de saúde. Repetindo o modelo da medicina baseada em evidência, que floresceu na área clínica, as avaliações de efetividade de programas de saúde pública têm proposto e empregado, preferentemente, estudos randomizados, como forma de garantir um padrão científico de credibilidade nos resultados. Uma nova tendência entre os intelectuais da epidemiologia aplicada aos serviços de saúde questiona essa premissa e propõe que os estudos randomizados sejam adaptados, para compreender a ampla cadeia causal que vincula a implementação de um programa a um determinado indicador de impacto. Outros desenhos, em níveis diferentes de inferência causal, mas suficientemente rigorosos para que seus resultados sejam confiáveis, são também propostos.
Health services epidemiological research generally involves testing the efficacy of new programs or strategies and the evaluation of health services quality. Repeating the evidence-based medicine model that has flourished in the clinical field, evaluations of public health programs' effectiveness has preferentially proposed and employed randomized studies as a way of guaranteeing a scientific standard of credibility in the results. A new trend among researchers of epidemiology applied to health services has challenged this premise and proposes that randomized studies be adapted to encompass the broad causal chain linking the implementation of programs to a given impact indicator. Others designs are proposed at different levels of causal inference, but sufficiently rigorous for their results to be reliable.
