Cardiopulmonary Bypass Video Is an Effective Learning Tool.

Surgical procedures require the collaboration of medical personnel with multiple skill sets who have different levels of training. Someone new to surgical procedures, such as a medical student, faces a steep learning curve. Studies have shown that video-assisted learning is associated with improved learning of surgical procedures. During their surgical rotation orientation, third-year medical students were invited via email to participate in a learning study featuring a cardiopulmonary bypass video. Study participants took a pretest, reviewed the locally developed video, and took a posttest and an attitudinal questionnaire after viewing the video. A convenience sample of 31 third-year medical students participated in the study. Overall knowledge scores improved from pretest to posttest (36.9% vs 79.6%, <0.001). In the posttest attitudinal questionnaire, students reported that they preferred video-assisted learning to reading written protocols (90.3% strongly agree/agree) and that they were more knowledgeable about the function of the cardiopulmonary bypass machine (80.7% strongly agree/agree) after viewing the video. Students also reported that the video would be useful during their surgical clerkships (90.4% strongly agree/agree). Video-assisted learning was associated with comprehension of the material immediately after viewing the video, and medical students considered it to be appropriate and useful. This educational video may benefit other learners who are entering the cardiopulmonary bypass operating room for the first time.
