Expert and informed decision making is an essential process in all of health care. Evidence-Based Medicine (EBM) purports to support and enhance this process by the timely infusion of high-quality, pertinent evidence from health research, tailored as closely as possible to the individual and their health problem. Doing so is not an easy task for many reasons, beginning with imperfections and incompleteness in the evidence and ending with the complexities of the dual decision making required by individuals and their care providers. EBM needs a lot of help supporting decision-making processes and welcomes further interdisciplinary collaboration. The “conformist principle,” “best practice regimens,” and “transductive models” should not be considered as barriers to such collaboration: These are not part of EBM. Rather, EBM has always seen evidence from health research as but one of many inputs to decision making by providers and patients. An overarching problem for collaboration to address is understanding the decision-making process well enough to develop effective means to bolster it, so that people are consistently offered the current best options for their problems in a way that fits their circumstances and that they can understand and judge.

In 2016, we examined the connection between naturalistic decision making and the trend toward best practice compliance; we used evidence-based medicine (EBM) in health care as an exemplar. Paul Falzer’s lead paper in this issue describes the historical underpinnings of how and why EBM came into vogue in health care. Falzer also highlights the epistemological rationale for EBM. Falzer’s article, like our own, questions the rationale of EBM and reflects on ways that naturalistic decision making can support expertise in the face of attempts to standardize practice and emphasize compliance. Our objectives in this commentary are first to explain the inherent limits of procedural approaches and second to examine ways to help decision makers become more adaptive.

Abstract Introduction Although evidence-based medicine (EBM) teaching activities may improve short-term EBM knowledge and skills, they have little long-term impact on learners’ EBM attitudes and behaviour. This study examined the effects of learning EBM through stand-alone workshops or various forms of deliberate EBM practice. Methods We assessed EBM attitudes and behaviour with the evidence based practice inventory questionnaire, in paediatric health care professionals who had only participated in a stand-alone EBM workshop (controls), participants with a completed PhD in clinical research (PhDs), those who had completed part of their paediatric residency at a department (Isala Hospital) which systematically implemented EBM in its clinical and teaching activities (former Isala residents), and a reference group of paediatric professionals currently employed at Isala’s paediatric department (current Isala participants). Results Compared to controls (n = 16), current Isala participants (n = 13) reported more positive EBM attitudes (p < 0.01), gave more priority to using EBM in decision making (p = 0.001) and reported more EBM behaviour (p = 0.007). PhDs (n = 20) gave more priority to using EBM in medical decision making (p < 0.001) and reported more EBM behaviour than controls (p = 0.016). Discussion Health care professionals exposed to deliberate practice of EBM, either in the daily routines of their department or by completing a PhD in clinical research, view EBM as more useful and are more likely to use it in decision making than their peers who only followed a standard EBM workshop. These findings support the use of deliberate practice as the basis for postgraduate EBM educational activities.

Within ‘evidence-based medicine and health care’ the ‘number needed to treat’ (NNT) has been promoted as the most clinically useful measure of the effectiveness of interventions as established by research. Is the NNT, in either its simple or adjusted form, ‘easily understood’, ‘intuitively meaningful’, ‘clinically useful’ and likely to bring about the substantial improvements in patient care and public health envisaged by those who recommend its use? The key evidence against the NNT is the consistent format effect revealed in studies that present respondents with mathematically-equivalent statements regarding trial results. Problems of understanding aside, trying to overcome the limitations of the simple (major adverse event) NNT by adding an equivalent measure for harm (‘number needed to harm’ NNH) means the NNT loses its key claim to be a single yardstick. Integration of the NNT and NNH, and attempts to take into account the wider consequences of treatment options, can be attempted by either a ‘clinical judgement’ or an analytical route. The former means abandoning the explicit and rigorous transparency urged in evidence-based medicine. The attempt to produce an ‘adjusted’ NNT by an analytical approach has succeeded, but the procedure involves carrying out a prior decision analysis. The calculation of an adjusted NNT from that analysis is a redundant extra step, the only action necessary being comparison of the results for each option and determination of the optimal one. The adjusted NNT has no role in clinical decision-making, defined as requiring patient utilities, because the latter are measurable only on an interval scale and cannot be transformed into a ratio measure (which the adjusted NNT is implied to be). In any case, the NNT always represents the intrusion of population-based reasoning into clinical decision-making.

Salah satu komponen latar belakang dari tujuan dilakukannya suatu penelitian adalah relevansi penelitian tersebut terhadap kemajuan ilmu pengetahuan, membuat kebijakan (policy) klinis dalam penatalaksanaan pasien secara individu ataupun kelompok serta kebijakan kesehatan secara lebih luas dalam suatu sistem tingkat institusi penyelenggara kesehatan baik tingkat rumah sakit (standard of procedures) maupun nasional (guidelines). Pada abad 21 ini dengan semakin meningkatnya tekanan dan tuntutan, pesatnya perkembangan teknologi kedokteran/kesehatan dan semakin terbatasnya sumber dana serta perubahan globalisasi, diharapkan pengambilan keputusan yang tepat dan baik akan bergeser ke arah ‘Evidence-based decision making’. “Evidence-based Medicine (EBM)” dan “Evidence-based Health Care (EBHC)” adalah cara pendekatan untuk mengambil keputusan dalam penatalaksanaan pasien (dan atau penyelenggaraan pelayanan kesehatan) secara eksplisit dan sistematis berdasarkan bukti penelitian terakhir yang sahih (valid) dan bermanfaat. Penerapan “Evidence-based Medicine (EBM)” dan “Clinical Governance” dalam suatu sistem organisasi pelayanan kesehatan memerlukan beberapa persyaratan yakni organisastion-wide transformation, clinical leadership dan positive organizational cultures.

Background: The quality and effectiveness of health care is largely determined by the quality of contact between doctor and patient. Possessing communicative skills and knowledge of effective means of medical communication allows a doctor of any specialty to solve more effectively complex tasks that arise in the medical-diagnostic process.  Methods: This review is based on materials of the articles on the recommendations of evidence-based medicine concerning the communication of doctors and patients in oncology, obstetrics and gynecology and pediatrics clinics.  Results: As result, we anticipate that this review will distribute and promote knowledge about methods of evidence-based medicine for improving communication in obstetrics-gynecology, pediatrics and oncology clinics. Conclusion: The physicians’ ability to communicate effectively is the key to a successful relationship between a patient and a doctor. The current state of the health care system requires increased clinical efficacy and less time for each patient, which may impede the quality of communication between the patient and the physician. The use of a patient-centered approach, empathy, shared decision-making improves the relationship between patient and physician, the effectiveness of therapy and increased adherence to prescribed treatment in oncology, obstetrics, gynecology and pediatrics.

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.
