Effect of Video-Based Coaching on Resident Laparoscopic Surgical Skills: A Randomized Controlled Trial
Effect of Video-Based Coaching on Resident Laparoscopic Surgical Skills: A Randomized Controlled Trial
Randomized controlled trial to evaluate the effect of video-based coaching on Obstetrics and Gynecology residents' efficiency, proficiency, and confidence in performing laparoscopic salpingectomy.
University of Texas Southwestern PGY-1 and PGY-2 Obstetrics and Gynecology residents will be scheduled to complete a 4-week gynecology rotation at Parkland Memorial Hospital. After completing the pre-survey, trainees will be randomized into either the control or experimental group (video coached group) stratified by PGY (Post-Graduate Year) level. Minimum group sample sizes of 9 and 9 to achieve 90% power to detect a difference of 5.0 in a design with 3 repeated measurements having a Simple covariance structure when the standard deviation is 5.4 and the alpha level is 0.05. The control group will be video recorded performing three laparoscopic salpingectomy procedures as scheduled during the 4-week block. The control group will not participate in video coaching sessions. The experimental group will be video recorded performing three laparoscopic salpingectomy procedures as scheduled during the block. After the first and second laparoscopic salpingectomy, the experimental group of residents will review their video recording and receive a video coaching session by a minimally invasive gynecologic surgery (MIGS) attending physician prior to the next surgery. All three video recordings for each participant (control and experimental group) will be graded using Global Operative Assessment of Laparoscopic Skills (GOALS) and Objective Structured Assessment of Laparoscopic Salpingectomy (OSA-LS) criteria by two attending physicians not involved in the surgeries or coaching. Each surgery will be blinded to the group allocation and the week definition. Participants will not be given the assessment score and the score will not affect evaluations. After the third laparoscopic salpingectomy, trainees will fill out a post-course survey to determine if the video-based coaching course improved their proficiency and confidence in laparoscopic gynecologic surgery. They will also watch their own laparoscopic salpingectomy video recording and self-grade their skills using the GOALS and OSA-LS criteria that will be provided in the post-survey.
