Principles of evidence-based medicine (EBM) may be inconsistently applied to clinical decision-making due to lack of practice-based training, experience, and time.
The authors sought to design, implement, and test the feasibility of an experiential learning model for senior emergency medicine (EM) residents to apply EBM principles during real-time clinical practice.
Targeted program evaluation of this learning model was conducted through a prospective observational cohort study involving EM residents at a large, urban, 4-year EM residency program. The curriculum development of a case-based knowledge translation shift followed Kern's six-step design process. Subjects asynchronously completed a 1-hour EBM tutorial and were then assigned to clinical shifts in which they contributed to the care of emergency department (ED) patients by completing formal literature searches related to active management questions. Pre- and post-intervention self-assessments of practice norms and attitudes were used to evaluate the effect of this experiential learning model for individual residents. Self-assessments of the likelihood that the experience would result in future practice change were reported on a five-point Likert scale (1 = greatly impeded, 2 = somewhat impeded, 3 = no change, 4 = somewhat improved, 5 = greatly improved). Subjects presented available evidence to the primary ED team, formally disseminated their findings as a brief "EBM rounds" at sign-out and completed an "EBM consult note" and case log to document shift performance. Changes in patient management and/or disposition were recorded. EBM search questions and resultant findings were entered in a local database.
Of the 45 eligible senior EM resident shifts, 91% resulted in complete sets of performance data and self-assessments. A total of 80 patient encounters were documented during 45 scheduled shifts over a 3-month study period. Literature review took a mean (±SD) of 36.2 (±26.4) minutes per case. During the 3-hour interval before or after shift sign-out, residents completed a mean (±SD) of 2.11 (±1.4) literature searches and recorded a mean (±SD) of 3.0 (±1.5) articles for each case. Alterations in ED management for 13 of 80 patient encounters (16.3%) were documented to be the direct result of on-shift literature searches.
Case-based knowledge translation shifts for senior EM residents can provide opportunities to practice EBM skills in the ED. This experiential learning model may result in future practice change by resident learners, as well as affect the management of active patients in the ED.
由于缺乏实践培训、经验和时间,循证医学(EBM)的原则在临床决策中可能应用不一致。
作者旨在设计、实施和测试一种经验学习模型,为高级急诊医学(EM)住院医师提供在实时临床实践中应用 EBM 原则的机会。
通过对一个大型城市 4 年制 EM 住院医师项目的 EM 住院医师进行前瞻性观察队列研究,对该学习模型进行有针对性的计划评估。案例为基础的知识转化转移课程开发遵循 Kern 的六步设计过程。研究对象异步完成了 1 小时的 EBM 教程,然后被分配到临床轮班,通过完成与主动管理问题相关的正式文献搜索,为急诊科(ED)患者的护理做出贡献。在干预前后,通过自我评估实践规范和态度来评估该经验学习模型对个体住院医师的影响。研究对象报告说,他们对经验可能导致未来实践改变的可能性的看法是基于五点李克特量表(1=极大地受阻,2=有些受阻,3=无变化,4=有些改善,5=极大地改善)。研究对象向主要 ED 团队提出了现有证据,正式将研究结果作为简短的“EBM 查房”在交班时公布,并完成“EBM 咨询记录”和病例日志以记录轮班表现。记录患者管理和/或处置的变化。EBM 搜索问题和结果发现被输入到本地数据库中。
在 45 名符合条件的高级 EM 住院医师轮班中,有 91%的轮班完成了完整的绩效数据和自我评估。在为期 3 个月的研究期间,45 次预定轮班共记录了 80 次患者就诊。文献复习平均(±SD)为每例 36.2(±26.4)分钟。在轮班交接班前或后的 3 小时内,住院医师平均(±SD)完成了 2.11(±1.4)次文献检索,并为每例病例记录了平均(±SD)3.0(±1.5)篇文章。ED 管理的改变发生在 80 例患者就诊中的 13 例(16.3%),这直接归因于轮班时的文献搜索。
高级 EM 住院医师的案例为基础的知识转化转移可以为在 ED 中实践 EBM 技能提供机会。这种经验学习模型可能会导致住院医师学习者未来的实践改变,同时也会影响 ED 中活动患者的管理。
