OBJECTIVE
To determine the impact of an online lecture versus a live lecture on screening given to medical students who are participating in an outpatient clerkship.
DESIGN
Prospective, randomized, controlled study.
PARTICIPANTS AND SETTING
Ninety-five senior medical students in a primary care medicine clerkship based at university and distant clinic sites.
INTERVENTION AND MEASUREMENTS
Forty-eight medical students were randomized to the live lecture on screening (live lecture group), and forty-seven medical students were randomized to the online lecture on screening (online lecture group). Outcome measures included students' knowledge, use of time, and satisfaction with the lecture experience.
RESULTS
Compared to students in the live lecture group, students in the online lecture group demonstrated equal post-intervention knowledge of screening (P =.91) and expended 50 minutes less time to complete the lecture. Online lecture students who used the audio feed of the lecture were equally satisfied with the lecture as the live lecture students. Without the audio feed, online lecture students were less satisfied.
CONCLUSIONS
An online lecture on screening is a feasible, efficient, and effective method to teach students on outpatient clerkships about principles of screening.
目的
确定在线讲座与现场讲座对参加门诊实习的医学生进行筛查教学的影响。
设计
前瞻性、随机对照研究。
参与者和背景
95名在大学及远程诊所站点进行初级保健医学实习的高年级医学生。
干预措施和测量方法
48名医学生被随机分配到筛查现场讲座组（现场讲座组），47名医学生被随机分配到筛查在线讲座组（在线讲座组）。结果指标包括学生的知识、时间利用情况以及对讲座体验的满意度。
结果
与现场讲座组的学生相比，在线讲座组的学生在干预后筛查知识水平相当（P = 0.91），且完成讲座的时间少花了50分钟。使用讲座音频的在线讲座组学生对讲座的满意度与现场讲座组学生相同。未使用音频时，在线讲座组学生的满意度较低。
结论
关于筛查的在线讲座是一种可行、高效且有效的方法，可用于向门诊实习的学生传授筛查原则。
