Skill acquisition and maintenance requires spaced deliberate practice. Assessing medical students' physical examination performance ability is resource intensive. The authors assessed the nature and size of physical examination performance samples necessary to accurately estimate total physical examination skill.
Physical examination assessment data were analyzed from second year students at the University of Illinois College of Medicine at Chicago in 2002, 2003, and 2004 (N = 548). Scores on subgroups of physical exam maneuvers were compared with scores on the total physical exam, to identify sound predictors of total test performance.
Five exam subcomponents were sufficiently correlated to overall test performance and provided adequate sensitivity and specificity to serve as a means to prompt continued student review and rehearsal of physical examination technical skills.
Selection and administration of samples of the total physical exam provide a resource-saving approach for promoting and estimating overall physical examination skills retention.
技能的习得与保持需要间隔性刻意练习。评估医学生的体格检查表现能力需要耗费大量资源。作者评估了准确估计总体格检查技能所需的体格检查表现样本的性质和规模。
分析了2002年、2003年和2004年芝加哥伊利诺伊大学医学院二年级学生的体格检查评估数据（N = 548）。将体格检查操作子组的分数与总体格检查的分数进行比较，以确定总体测试表现的可靠预测指标。
五个检查子组件与总体测试表现具有足够的相关性，并提供了足够的敏感性和特异性，可作为促使学生继续复习和演练体格检查技术技能的一种手段。
选择并实施总体格检查样本，为促进和估计总体格检查技能的保持提供了一种节省资源的方法。
