目的.直肠指诊（DRE）是一个完整的身体检查和评估病人的必要组成部分，但这项检查的教学，医学生往往是不够的。本研究是一项比较评估的有效性的直肠教学助理（RTA），讲座，角色扮演，和模拟模型作为教学DRE程序的方法，本科医学生在纽芬兰纪念大学医学院。共有65名三年级医学生被随机分配到实验组或控制组。两组都接受了讲座并在模拟模型上练习了DRE。实验组接受RTA的进一步培训。学生完成了干预前和干预后的知识评估，客观的结构化临床考试（OSCE）测量DRE的性能，和满意度调查。两组的平均知识得分均显著增加（18.73至22.32，p <0.0001）。对照组在干预后评估中的得分显著高于实验组（23.11比21.47，P = .025）。实验组在OSCE中的得分更高（27.52比23.80，P = .001），并将RTA评为学习DRE的更有效方法。这是第一项使用RTA来教授DRE作为评估直肠的整体技能的研究，表明RTA方法对于提高技能和学生对该程序的信心是有效的。
Purpose. The digital rectal examination (DRE) is a necessary part of a complete physical examination and evaluation of a patient, yet teaching of this examination to medical students is often inadequate. This study was a comparative evaluation of the effectiveness of the rectal teaching associate (RTA), lecture, role-playing, and simulated models as methods for teaching the DRE procedure to undergraduate medical students at Memorial University of Newfoundland Faculty of Medicine.Method. A total of 65 third-year medical students were randomly assigned to either an experimental or control group. Both groups received a lecture and practiced the DRE on a simulated model. The experimental group received further training from an RTA. Students completed a pre- and post-intervention knowledge assessment, an objective structured clinical exam (OSCE) measuring performance of the DRE, and a satisfaction survey.Results. Mean knowledge scores increased significantly for both groups (18.73 to 22.32, p < .0001). The control group scored significantly higher on the post-intervention assessment than did the experimental group (23.11 versus 21.47, P = .025) The experimental group scored higher on the OSCE (27.52 versus 23.80, p = .001) and rated the RTA as a more effective method for learning the DRE.Conclusions. This first study using RTAs to teach the DRE as a global skill for evaluating the rectum suggests that the RTA method is effective for increasing skills and students' confidence in the procedure.
