Efficacy of Video versus Verbal Feedback in Surgical Training Using Simulated Laparoscopic Vaginal Cuff Closure
Purpose: The purpose of this
study is to compare the efficacy of video-based feedback to standard verbal
feedback in improving OB/GYN residents’ surgical skills using a validated
simulated laparoscopic vaginal cuff closure (SLVCC) model.
feedback on performance is integral to surgical training. Recently, there has
been interest in the incorporation of video-based feedback. However, the
efficacy of video-based feedback remains unclear.
designed a prospective, randomized cross-over study utilizing a validated SLVCC
model. Eighteen OB/GYN residents participating in the study completed the
SLVCC, received feedback on their performance and then repeated the task. Tasks
were video-recorded and participants were randomized to receive verbal or
video-based feedback. After a washout period of two months, the process was
repeated with residents receiving the alternative form of feedback. Surgical
performance was assessed by two independent expert surgeons using the validated
OSATS model. Additional metrics included time to SLVCC completion and a
validated assessment of resident self-efficacy. The two sided paired t-test
was used for statistical analysis using the significance level of 5% with an
effect size of 0.6.
was no statistically significant difference between video-based and standard
verbal feedback in either study phase with regard to improvement in time to
completion of task (p=0.17, 0.18), OSATS scoring (p=0.48, 0.91), or residents’
reported self-efficacy (p=0.73, 0.80).
Discussions: Our finding that
video-based feedback is not superior to structured verbal feedback is
consistent with prior studies. However, larger studies are needed to further
clarify the role of video-based feedback in surgical education.
