This chapter presents a detailed case study of a sham knee surgery case. The knee case is illustrative of systemic problems in the promotion of evidence-based medicine. Clearly, many medical societies are failing to take seriously their professional responsibility to deliver evidence-based care to patients and ensure that the nation does not squander scarce health care dollars on treatments of dubious worth. The chapter describes how the orthopedic community mostly ignored clear warnings that the arthroscopic surgery for osteoarthritis (OA) of the knee might not be effective. It also reviews the Moseley-Wray study's findings and looks at the less than optimal responses they prompted from medical societies and policy makers. The chapter then considers the debate surrounding another procedure for knee OA (arthroscopic partial meniscectomy) that has grown in popularity despite a lack of evidence, and identifies signs of the same performance pathologies.

There is increasing pressure from industry to use advanced wound care products and technologies. Many are very expensive but promise to reduce overall costs associated with wound care. Compelling anecdotal evidence is provided that inevitably shows wounds that failed all other treatments but responded positively to the subject product. Evidence-based medicine is the standard by which physician-scientists must make their clinical care decisions. In an attempt to provide policy makers with the most current evidence on advanced wound care products, the Department of Veteran Affairs conducted an Evidence-based Synthesis Program review of advanced wound care products. This paper suggests how to take this information and apply it to policy to drive evidence-based care to improve outcomes and fiduciary responsibility.

Decision-making is an essential process that everyone takes upon at all times. Healthcare managers make decisions to ensure serving high quality of patient care, reduce costs and allocate resources. Evidence based decision making in healthcare has recently received a lot of attention by all health care stakeholders including clinicians, researchers, managers and policy makers. However, it is more adapted by clinicians and researchers than managers and policy makers. Evidence-Based science began to develop in the early 90s and was later named “Evidence Based Medicine” after its methods have been applied in health-related fields. Yet, Evidence Based Management still showing a slow progress in terms of its application in decision-making in practice worldwide. This chapter seeks to examine the key aspects of decision-making in the health care settings. It further seeks to provide key examples of decision-making and ways to seek evidence, types of evidence, and approaches to making evidence-based decisions.

Em 2005, o grego John Loannidis, professor da Universidade de Stanford, publicou um artigo na PLOS Medicine intitulado “Why most published research findings are false” [1]. Ele que é dos pioneiros da chamada “meta-ciência”, disciplina que analisa o trabalho de outros cientistas, avaliou se estão respeitando as regras fundamentais que definem a boa ciência. Esse trabalho foi visto com muito espanto e indignação por parte dos pesquisadores na época, pois colocava em xeque a credibilidade da ciência.Para muitos cientistas, isso acontece porque a forma de se produzir conhecimento ficou diferente, ao ponto que seria quase irreconhecível para os grandes gênios dos séculos passados. Antigamente, se analisavam os dados em estado bruto, os autores iam às academias reproduzir suas experiências diante de todos, mas agora isso se perdeu porque os estudos são baseados em seis milhões de folhas de dados. Outra questão importante que garantia a confiabilidade dos achados era que os cientistas, independentemente de suas titulações e da relevância de suas descobertas anteriores, tinham que demonstrar seus novos achados diante de seus pares que, por sua vez, as replicavam em seus laboratórios antes de dar credibilidade à nova descoberta. Contudo, na atualidade, essas garantias veem sendo esquecidas e com isso colocando em xeque a validade de muitos estudos na área de saúde.Preocupados com a baixa qualidade dos trabalhos atuais, um grupo de pesquisadores se reuniram em 2017 e construíram um documento manifesto que acabou de ser publicado no British Medical Journal “Evidence Based Medicine Manifesto for Better Health Care” [2]. O Documento é uma iniciativa para a melhoria da qualidade das evidências em saúde. Nele se discute as possíveis causas da pouca confiabilidade científica e são apresentadas algumas alternativas para a correção do atual cenário. Segundo seus autores, os problemas estão presentes nas diferentes fases da pesquisa:Fases da elaboração dos objetivos - Objetivos inúteis. Muito do que é produzido não tem impacto científico nem clínico. Isso porque os pesquisadores estão mais interessados em produzir um número grande de artigos do que gerar conhecimento. Quase 85% dos trabalhos não geram nenhum benefício direto a humanidade.Fase do delineamento do estudo - Estudos com amostras subdimensionados, que não previnem erros aleatórios. Métodos que não previnem erros sistemáticos (viés na escolha das amostras, falta de randomização correta, viés de confusão, desfechos muito abertos). Em torno de 35% dos pesquisadores assumem terem construídos seus métodos de maneira enviesada.Fase de análise dos dados - Trinta e cinco por cento dos pesquisadores assumem práticas inadequadas no momento de análise dos dados. Muitos assumem que durante esse processo realizam várias análises simultaneamente, e as que apresentam significância estatística são transformadas em objetivos no trabalho. As revistas também têm sua parcela de culpa nesse processo já que os trabalhos com resultados positivos são mais aceitos (2x mais) que trabalhos com resultados negativos.Fase de revisão do trabalho - Muitos revisores de saúde não foram treinados para reconhecer potenciais erros sistemáticos e aleatórios nos trabalhos.Em suma é necessário que pesquisadores e revistas científicas pensem nisso. Só assim, teremos evidências de maior qualidade, estimativas estatísticas adequadas, pensamento crítico e analítico desenvolvido e prevenção dos mais comuns vieses cognitivos do pensamento.

The objective: was to study the international experience of evidence based preventive medicine development as well as to estimate its perspectives in Ukraine. Patients and methods. Main principles and methods of scientific knowledge and research have been used including universal ones, methods of systemic approach, quantitative and qualitative information analysis, classification and systematization of theoretical and empirical data, hystorical and logical methods, health statistics as well). In total 529 scientific information sources have been studied, particularly a number of evidence based medicine (EBM) computer databases, special task forces recommendations and Cochrane reviews on prevention, Register of medical and technological documents for health care standards in Ukraine et al. Results. The contribution of foreign scientific schools in the development of EBM has been determined, as well as the crucial role of scientific works carried out in the US and Great Britain in 1930–80s as to the development of evidence based preventive medicine. The international experience of the development and functioning of evidence based practice centers’ and special task forces on prevention has been summarized, as the experience of the development and implementation of recommendations on prevention in primary health care (PHC) in high income countries acceptable for Ukraine. The concept of evidence based prevention has been first proposed. It is revealed, that EBM implementation in Europe has been prioritized in both the field of infectious diseases prevention and PHC, while there are both the development of differentiated evidence based prevention and early evidence based diagnosis in PHC in the US. Conclusion. The results proved importance of taking into consideration of international experience while evidence based PHC is being developed as a priority in Ukraine.

This case study describes a longitudinal curricular sequence implemented to teach evidence-based medicine (EBM) skills. The longitudinal sequence is innovative in its approach, design, and assessment of EBM. This approach moves away from the conventional strategy of teaching drug information and drug literature evaluation as stand-alone courses and instead embraces the EBM Framework and its use in the context of authentic problem solving. The EBM Framework—Ask, Acquire, Appraise, and Apply—was used as the basis for defining seven EBM skills. These skills were targeted in the evidence-based, integrated design of 17 learning episodes delivered with eight faculty members through six courses in the first year. Student perceptions of relevance of EBM and performance on assessments and learning activities throughout the sequence suggest that integrating EBM across the first year of the curriculum is an effective strategy for teaching EBM skills. Three themes emerged from analysis of the data and experience, including the need for: a strong teaching team, a whole task approach with a focus on solving authentic problems, and care in interpreting the progression of assessments and patterns of student performance. Through instructor observations and peer review, the longitudinal sequence has been refined and has had an impact on the rest of the curriculum.   Type: Case Study

In an era of evidence-based medicine, policy-makers and researchers are preoccupied by the task of ensuring that advances in research are implemented in routine clinical practice. This preoccupation has spawned a small but growing research industry of its own, with the development of resources such as the Cochrane Collaboration database and journals such as Evidence-Based Mental Health. In this paper, I adopt a philosophically quite unfashionable methodology – introspection – to address the question: how has research affected my practice?
