BACKGROUND
A "lectures plus clinical experiences" curriculum for surgical clerkships has significant faculty demand. A less faculty-intense blended online curriculum (BOC) could provide similar/improved academic performance compared with traditional curricula (TCs).
METHODS
Following an initial pilot study, students in the surgery clerkship at Johns Hopkins during 2013 to 2014 experienced a BOC (n = 129). Students the preceding year (2012 to 2013) experienced the TC (n = 108). Performance and satisfaction were compared between groups using clinical evaluations, National Board of Medical Examiners examination scores, and clerkship evaluations.
RESULTS
No significant differences in academic performance between BOC and TC students were observed on National Board of Medical Examiners examination or clinical evaluation scores. After multivariable adjustment, student year was the only significant predictor of student performance. Clerkship teaching ratings were higher for BOC students than TC students (4.25/5 vs 3.98/5, P = .03).
CONCLUSIONS
BOC incorporation in the basic surgery clerkship resulted in noninferior academic outcomes and significantly improved student satisfaction.
背景
外科实习的“讲座加临床经验”课程对师资要求很高。与传统课程（TC）相比，师资需求较低的混合式在线课程（BOC）可能会带来相似或更好的学业成绩。
方法
在初步试点研究之后，2013年至2014年期间约翰·霍普金斯大学外科实习的学生采用了BOC课程（n = 129）。前一年（2012年至2013年）的学生采用了TC课程（n = 108）。使用临床评估、美国国家医学考试委员会考试成绩和实习评估对两组之间的表现和满意度进行了比较。
结果
在国家医学考试委员会考试或临床评估成绩方面，未观察到BOC组和TC组学生在学业成绩上有显著差异。经过多变量调整后，学生年级是学生表现的唯一显著预测因素。BOC组学生的实习教学评分高于TC组学生（4.25/5对3.98/5，P = .03）。
结论
在基础外科实习中采用BOC课程导致学业成绩不低于传统课程，并显著提高了学生满意度。
