Evidence-based medicine (EBM) integrates individual clinical expertise with the best available external evidence in the care of individual patients. By enabling clinicians to directly appraise and apply current clinical research, EBM deals with the problems of deterioration in clinical performance, information overload, and lag in application of research findings to clinical practice. Thus, EBM is a useful tool to address the problems faced by clinicians attempting to provide optimum, current care for their patients. The rationale for EBM, its principles and application, as well as some limitations, are described here.

Evidence-based medicine (EBM) is an effective tool for identifying and critically appraising quality research findings, and allowing the best to be integrated within clinical practice. EBM requires familiarity with evidence grading systems, key statistical methods, and requires a good understanding of how to review and critique scientific papers to guide the clinical practice. This chapter introduces these tools and provide an easy-to-use layout for reading academic papers in hand.

<p>The Journal's Editor holds that, although Evidence-based medicine typically only looks for bias of the research design, still evidence-based practice must also include the biases of those using the research evidence and how it is deployed in clinical practice.</p>

Currently, it is impossible to think of modern healthcare that ignores evidence-based medicine (EBM), a concept which relies on 3 pillars: individual clinical expertise, the values and desires of the patient, and the best available research. However, EBM is not perfect. Clinical research is also far from being perfect. This article provides an overview of the basic principles, opportunities, and controversies offered by EBM. It also summarizes current discussions on clinical research. Potential solutions to the problems of EBM and clinical research are discussed as well. If there were specific issues related to pediatric nutrition, an attempt was made to discuss the basic principles and limitations in this context. However, the conclusions are applicable to EBM and clinical research in general. In the future, considering that new ways of obtaining health data will continue to emerge, the world of EBM and clinical research is likely to change. The ultimate goal, however, will remain the same: improving health outcomes for patients.

Evidence Based Medicine integrates clinical expertise, best available clinical evidence, as well as patient’s values and preferences to manage the care of patients. Surgeons have traditionally performed surgery according to their mentor teachings, these techniques being passed down through several generations. Current surgeon culture must evolve to integrate EBM into their clinical practice. The knowledge and skills required for searching and appraising critical literature needs to be taught to enable surgeons to implement it effectively. Evidence based surgery (EBS) will encourage surgeons to apply the best up-to-date knowledge to find the most effective surgical management plan for their patients. Several methods of teaching EBS to surgical trainees have shown to be effective including workshops, small group discussions, lecture style teaching and courses involving a combination of techniques. Journal clubs have gained in popularity and provided excellent teaching environments for surgeons to learn critical appraisal. Recently EBM has been introduced into the undergraduate programme to provide young medical practitioners with a strong foundation in EBM competency, and a positive attitude towards applying EBM to clinical practice. In this review, we aim to provide an overview of the principles of EBM and the success and challenges of teaching methods to deliver EBM for the surgical field.

Over the last five years the adjective ‘evidence-based’ has become difficult to avoid. Indeed, a MEDLINE search for articles containing the phrase ‘evidence-based medicine’ in their titles or abstracts reveals one mention in 1992, rapidly increasing to 53 in 1996. So great has been the increase that the National Library of Medicine now includes ‘evidence-based medicine’ as a MeSH heading for indexing papers.But what is evidence-based medicine (EBM)? First and foremost, EBM is a set of strategies designed to help the clinician keep up-to-date and to base his clinical decision making on the best available external evidence. EBM has been espoused by policymakers, purchasers and others — and, although the approach is open to misuse by these groups as a cost-cutting exercise, there are refreshing signs that they will be able to use the approach to help produce real improvements in patient care. However, the essential focus of EBM is on assisting doctors and other clinicians make decisions about individual patients. The steps involved in EBM include: a precise definition of the clinical problem (a crucial first step — in medical practice it will usually include making a diagnosis), an efficient search for the best available evidence, critical appraisal of the evidence and integration of the research findings with clinical expertise. Finally, the clinician assesses the outcome of the process and continues to improve his EBM skills.

ABSTRACT Evidence-based medicine is the conscientious use of the current best evidence in making health care decisions. It involves the incorporation of research findings, patient values and preferences, clinical circumstances and your own clinical expertise. This approach is not a blinkered adherence to only randomized trials, but to the best available evidence in clinical decision making. The skills of an EBM practitioner require asking clinically important questions, conducting searches for the best available evidence, appraising this evidence critically, and deciding whether to apply this evidence to patients.

Evidence based medicine (EBM) is the integration of best research evidence with clinical expertise and patient values. In the practice of EBM it is the physician’s duty to find the best and most current information and apply it judiciously for the benefit of the patient. The practice of EBM involves formulating a clear clinical question from a patient’s problem, searching the literature to acquire the evidence, then critically appraising the evidence for its validity and usefulness, and applying the results by implementing useful findings into clinical practice, and finally evaluating this application of evidence on patient. An important rule in EBM is that it starts with the patient and ends with the patient. Evidence based medicine requires new skills of the physician, including efficient literature searching and the application of formal rules of evidence evaluation from the clinical literature. Incorporation of EBM into one’s practice will not only make one a better clinician, it also allows one to provide the best possible quality of medical care to his or her patients. Thus EBM can be incorporated as an integral part of the medical curriculum.

Purpose The current investigation is a follow-up from a previous study examining child language diagnostic decision making in school-based speech-language pathologists (SLPs). The purpose of this study was to examine the SLPs' perspectives regarding the use of evidence-based practice (EBP) in their clinical work. Method Semistructured phone interviews were conducted with 25 school-based SLPs who previously participated in an earlier study by Fulcher-Rood et al. 2018). SLPs were asked questions regarding their definition of EBP, the value of research evidence, contexts in which they implement scientific literature in clinical practice, and the barriers to implementing EBP. Results SLPs' definitions of EBP differed from current definitions, in that SLPs only included the use of research findings. SLPs seem to discuss EBP as it relates to treatment and not assessment. Reported barriers to EBP implementation were insufficient time, limited funding, and restrictions from their employment setting. SLPs found it difficult to translate research findings to clinical practice. SLPs implemented external research evidence when they did not have enough clinical expertise regarding a specific client or when they needed scientific evidence to support a strategy they used. Conclusions SLPs appear to use EBP for specific reasons and not for every clinical decision they make. In addition, SLPs rely on EBP for treatment decisions and not for assessment decisions. Educational systems potentially present other challenges that need to be considered for EBP implementation. Considerations for implementation science and the research-to-practice gap are discussed.

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.
