Objective:
Traditionally, expert surgeons have provided surgical trainees with feedback about their simulation performance, including for asynchronous practice. Unfortunately, innumerable time demands may limit experts' ability to provide feedback. It is unknown whether and how peer feedback is an effective mechanism to help residents acquire laparoscopic skill in an asynchronous setting. As such, we aimed to assess the effect of peer feedback on laparoscopic performance and determine how residents perceive giving and receiving peer feedback.
Design:
We conducted a convergent mixed methods study. In the quantitative component, we randomized residents to receive feedback on home laparoscopic tasks from peers or faculty. We then held an end-of-curriculum, in-person laparoscopic assessment with members from both groups and compared performance on the in-person assessment between the groups. In the qualitative component, we conducted interviews with resident participants to explore experiences with feedback and performance. Three authors coded and rigorously reviewed interview data using a directed content analysis.
Setting:
We performed this study at a single tertiary academic institution: the University of California, San Francisco.
Participants:
We invited 47 junior residents in general surgery, obstetrics-gynecology, and urology to participate, of whom 37 (79%) participated in the home curriculum and 25 (53%) participated in the end-of-curriculum assessment.
Results:
Residents in the peer feedback group scored similarly on the final assessment (mean 70.7%; SD 16.1%) as residents in the faculty feedback group (mean 71.8%; SD 11.9%) (p = 0.86). Through qualitative analysis of interviews with 13 residents, we identified key reasons for peer feedback's efficacy: shared mental models, the ability to brainstorm and appreciate new approaches, and a low-stakes learning environment.
Conclusions:
We found that peer and faculty feedback led to similar performance in basic laparoscopy and that residents engaged positively with peer feedback, suggesting that peer feedback can be used when residents learn basic laparoscopy.
