Rationale, aims and objectives Although many believe that evidence-based practice (EBP) has great potential, critics have identified limitations including a focus on randomized clinical trial (RCT) evidence to the exclusion of other evidence types and a disregard for the art of medicine. Others have argued, however, that proper application of EBP involves reasoned consideration of a wide variety of information; thus, the dichotomy between medical science and art may be false. We explore the views of executive-level policymakers from the Veterans Health Administration, a leader in the EBP movement, regarding what constitutes evidence and the relative importance of evidence versus practical needs when determining clinical policy. Method We conducted 26 semi-structured qualitative interviews and performed a content analysis. Results Although informants generally believed in the value of EBP and the role of RCTs within it, they also valued other types of evidence. Further, they had concerns that were sometimes antithetical with strict adherence to an evidence-based approach. These included practical concerns, fit with organizational values and with local circumstances, resources, political pressures and patient needs. They were especially concerned about how to address medical conditions that affect many individuals or high-risk populations that have no evidence-based treatment. Conclusion When possible, health care practice should be evidence-based. When this is not possible, health care providers must turn to the art of medicine by using consensus-based best practices. Further, it is important for policymakers and researchers to work in concert to develop EBPs that are practical and meet needs.
虽然许多人认为循证实践(EBP)具有巨大的潜力,但批评者也指出了其局限性,包括过分关注随机临床试验(RCT)证据而排除其他证据类型,以及忽视医学艺术。然而,也有人认为,正确应用 EBP 需要合理考虑各种信息;因此,医学科学与艺术之间的二分法可能是错误的。我们探讨了退伍军人健康管理局(VHA)的高管决策者对构成证据的看法,以及在确定临床政策时,证据与实际需求的相对重要性。
我们进行了 26 次半结构化定性访谈,并进行了内容分析。
尽管受访者普遍相信 EBP 的价值以及 RCT 在其中的作用,但他们也重视其他类型的证据。此外,他们还存在一些担忧,这些担忧有时与严格遵循循证方法相矛盾。这些担忧包括实际问题、与组织价值观和当地情况、资源、政治压力和患者需求的契合度。他们尤其关注如何处理影响许多个人或高危人群的医疗状况,这些人没有循证治疗方法。
在可能的情况下,医疗实践应基于证据。当这不可能时,医疗保健提供者必须通过使用基于共识的最佳实践来诉诸医学艺术。此外,政策制定者和研究人员共同努力制定实用且满足需求的 EBP 非常重要。
