“…This overview synthesized evidence from systematic reviews of studies of teaching EBHC at undergraduate or postgraduate level and the impact of this teaching on EBHC competencies. It took a systematic approach to gather, evaluate and organize the evidence that had been brought together in several systematic reviews [46], [47] on teaching EBHC, taking into consideration factors such as type of teaching and target audience, in order to improve access to the evidence and to inform EBHC teaching approaches.…”

BackgroundAn evidence-based approach to health care is recognized internationally as a key competency for healthcare practitioners. This overview systematically evaluated and organized evidence from systematic reviews on teaching evidence-based health care (EBHC).Methods/FindingsWe searched for systematic reviews evaluating interventions for teaching EBHC to health professionals compared to no intervention or different strategies. Outcomes covered EBHC knowledge, skills, attitudes, practices and health outcomes. Comprehensive searches were conducted in April 2013. Two reviewers independently selected eligible reviews, extracted data and evaluated methodological quality. We included 16 systematic reviews, published between 1993 and 2013. There was considerable overlap across reviews. We found that 171 source studies included in the reviews related to 81 separate studies, of which 37 are in more than one review. Studies used various methodologies to evaluate educational interventions of varying content, format and duration in undergraduates, interns, residents and practicing health professionals. The evidence in the reviews showed that multifaceted, clinically integrated interventions, with assessment, led to improvements in knowledge, skills and attitudes. Interventions improved critical appraisal skills and integration of results into decisions, and improved knowledge, skills, attitudes and behaviour amongst practicing health professionals. Considering single interventions, EBHC knowledge and attitude were similar for lecture-based versus online teaching. Journal clubs appeared to increase clinical epidemiology and biostatistics knowledge and reading behavior, but not appraisal skills. EBHC courses improved appraisal skills and knowledge. Amongst practicing health professionals, interactive online courses with guided critical appraisal showed significant increase in knowledge and appraisal skills. A short workshop using problem-based approaches, compared to no intervention, increased knowledge but not appraisal skills.ConclusionsEBHC teaching and learning strategies should focus on implementing multifaceted, clinically integrated approaches with assessment. Future rigorous research should evaluate minimum components for multifaceted interventions, assessment of medium to long-term outcomes, and implementation of these interventions.

Este projeto de pesquisa teve como objetivo geral identificar estratégias de implementação das diretrizes para a detecção precoce do câncer de mama no Brasil. Em relação aos objetivos específicos, propôs-se a identificar, na literatura especializada, estudos sobre as dificuldades e as estratégias de implementação das diretrizes para a detecção precoce do câncer de mama nos sistemas de saúde de diferentes países; a avaliar a aplicabilidade dos resultados encontrados no contexto brasileiro; e a recomendar ações prioritárias conforme as estratégias de implementação das diretrizes às organizações responsáveis por esses processos no âmbito da saúde pública. Foi realizada uma revisão de revisões sistemáticas utilizando as ferramentas supporting policy relevant reviews and trial (SUPPORT), para auxiliar na estruturação das buscas e na análise de dados. As bases de dados utilizadas foram PubMed/MEDLINE, Cochrane Library, Biblioteca Virtual em Saúde (BVS)/Literatura Latino-Americana e do Caribe em Ciências da Saúde (Lilacs) e Embase de 1º de janeiro de 2008 a 1º de maio de 2018. O estudo de nove revisões sistemáticas selecionadas identificou ações exitosas em países desenvolvidos e em desenvolvimento. As estratégias identificadas foram: fomento de lideranças comprometidas com a implementação das diretrizes, melhor governança dos serviços de saúde próximos ao público-alvo, campanha nacional de divulgação em massa e programa de navegação de pacientes.PALAVRAS-CHAVE: detecção precoce de câncer; neoplasias da mama; políticas públicas de saúde. RESUMO ABSTRACTThis research project aimed to identify strategies for implementing guidelines for early detection of breast cancer in Brazil. Regarding the specific objectives, it aimed to identify studies in the specialized literature on the difficulties and strategies for implementing the guidelines for early detection of breast cancer in the health systems of different countries; to evaluate the applicability of the results found in the Brazilian context; and to recommend priority actions in accordance with the implementation strategies of the guidelines to the organizations responsible for these processes in the public health context. A review of systematic reviews was carried out using the supporting policy relevant reviews and trial (SUPPORT) tools to assist in structuring searches and analyzing data. The databases used were . The study of nine selected systematic reviews identified successful actions in developed and developing countries. The strategies identified were: promotion of leadership fronts committed to the implementation of the guidelines, better governance of health services close to the target audience, national mass dissemination campaign and patient navigation program.

“…Alternatively, the growing number of published systematic reviews and meta-analyses offers an opportunity to conduct multiple-indication reviews through overviews of systematic reviews [23,24]. This approach provides a practical solution for dealing with large volume of evidence that would otherwise not be feasible to review within usual time and resource constraints.…”
