For evidence-based practice to embed culturally in the workplace, teaching of evidence-based medicine (EBM) should be clinically integrated. In low-middle-income countries (LMICs) there is a scarcity of EBM-trained clinical tutors, lack of protected time for teaching EBM, and poor access to relevant databases in languages other than English.
To evaluate the effects of a clinically integrated e-learning EBM course incorporating the World Health Organization (WHO) Reproductive Health Library (RHL) on knowledge, skills, and educational environment compared with traditional EBM teaching.
DESIGN, SETTING, AND PARTICIPANTS: International cluster randomized trial conducted between April 2009 and November 2010 among postgraduate trainees in obstetrics-gynecology in 7 LMICs (Argentina, Brazil, Democratic Republic of the Congo, India, Philippines, South Africa, Thailand). Each training unit was randomized to an experimental clinically integrated course consisting of e-modules using the RHL for learning activities and trainee assessments (31 clusters, 123 participants) or to a control self-directed EBM course incorporating the RHL (29 clusters, 81 participants). A facilitator with EBM teaching experience was available at all teaching units. Courses were administered for 8 weeks, with assessments at baseline and 4 weeks after course completion. The study was completed in 24 experimental clusters (98 participants) and 22 control clusters (68 participants).
Primary outcomes were change in EBM knowledge (score range, 0-62) and skills (score range, 0-14). Secondary outcome was educational environment (5-point Likert scale anchored between 1 [strongly agree] and 5 [strongly disagree]).
At baseline, the study groups were similar in age, year of training, and EBM-related attitudes and knowledge. After the trial, the experimental group had higher mean scores in knowledge (38.1 [95% CI, 36.7 to 39.4] in the control group vs 43.1 [95% CI, 42.0 to 44.1] in the experimental group; adjusted difference, 4.9 [95% CI, 2.9 to 6.8]; P < .001) and skills (8.3 [95% CI, 7.9 to 8.7] vs 9.1 [95% CI, 8.7 to 9.4]; adjusted difference, 0.7 [95% CI, 0.1 to 1.3]; P = .02). Although there was no difference in improvement for the overall score for educational environment (6.0 [95% CI, -0.1 to 12.0] vs 13.6 [95% CI, 8.0 to 19.2]; adjusted difference, 9.6 [95% CI, -6.8 to 26.1]; P = .25), there was an associated mean improvement in the domains of general relationships and support (-0.5 [95% CI, -1.5 to 0.4] vs 0.3 [95% CI, -0.6 to 1.1]; adjusted difference, 2.3 [95% CI, 0.2 to 4.3]; P = .03) and EBM application opportunities (0.5 [95% CI, -0.7 to 1.8] vs 2.9 [95%, CI, 1.8 to 4.1]; adjusted difference, 3.3 [95% CI, 0.1 to 6.5]; P = .04).
In a group of LMICs, a clinically integrated e-learning EBM curriculum in reproductive health compared with a self-directed EBM course resulted in higher knowledge and skill scores and improved educational environment.

为了使循证医学在工作场所实现文化融合,循证医学(EBM)的教学应该与临床相结合。在中低收入国家(LMICs),缺乏经过 EBM 培训的临床导师,用于教学 EBM 的受保护时间不足,而且难以获取以英语以外的其他语言编写的相关数据库。
评估一项将世界卫生组织(WHO)生殖健康图书馆(RHL)纳入其中的临床整合型电子学习循证医学课程对知识、技能和教育环境的影响,与传统循证医学教学进行比较。
设计、地点和参与者:这是一项于 2009 年 4 月至 2010 年 11 月在 7 个中低收入国家(阿根廷、巴西、刚果民主共和国、印度、菲律宾、南非和泰国)的妇产科研究生中进行的国际集群随机试验。每个培训单位被随机分配到一个实验性临床整合课程,该课程由使用 RHL 进行学习活动和学员评估的电子模块组成(31 个集群,123 名参与者),或分配到一个包含 RHL 的对照自我指导 EBM 课程(29 个集群,81 名参与者)。在所有教学单位都配备了具有 EBM 教学经验的促进者。课程为期 8 周,在课程结束后的 4 周进行评估。该研究完成了 24 个实验组(98 名参与者)和 22 个对照组(68 名参与者)。
主要结局指标是 EBM 知识(评分范围,0-62)和技能(评分范围,0-14)的变化。次要结局指标是教育环境(5 分李克特量表,锚定在 1(非常同意)到 5(非常不同意)之间)。
在基线时,研究组在年龄、培训年限以及 EBM 相关态度和知识方面相似。试验后,实验组的知识得分更高(对照组为 38.1[95%置信区间,36.7 至 39.4],实验组为 43.1[95%置信区间,42.0 至 44.1];调整差异,4.9[95%置信区间,2.9 至 6.8];P<0.001)和技能(对照组为 8.3[95%置信区间,7.9 至 8.7],实验组为 9.1[95%置信区间,8.7 至 9.4];调整差异,0.7[95%置信区间,0.1 至 1.3];P=0.02)。尽管教育环境的整体评分改善没有差异(对照组为 6.0[95%置信区间,-0.1 至 12.0],实验组为 13.6[95%置信区间,8.0 至 19.2];调整差异,9.6[95%置信区间,-6.8 至 26.1];P=0.25),但在一般关系和支持领域(对照组为-0.5[95%置信区间,-1.5 至 0.4],实验组为 0.3[95%置信区间,-0.6 至 1.1];调整差异,2.3[95%置信区间,0.2 至 4.3];P=0.03)和 EBM 应用机会领域(对照组为 0.5[95%置信区间,-0.7 至 1.8],实验组为 2.9[95%置信区间,1.8 至 4.1];调整差异,3.3[95%置信区间,0.1 至 6.5];P=0.04)存在平均改善。
在一组中低收入国家中,与自我指导的 EBM 课程相比,生殖健康方面的临床整合型电子学习循证医学课程可提高知识和技能评分,并改善教育环境。
