摘要
Objective We sought to validate a simulation model for robotic sacrocolpopexy (RSCP) that includes multiple steps: presacral dissection/mesh attachment, vaginal mesh attachment, and peritoneal closure. Methods An RSCP training model was developed. Female pelvic medicine and reconstructive surgery (FPMRS) experts and current FPMRS fellows were videotaped using the model; sessions were timed and scored using the Global Evaluative Assessment of Robotic Skills (GEARS) by 3 surgeon reviewers masked to participants' identities. Construct validity was measured by comparing performance on the model between experts and trainees. Interrater reliability was determined by calculating intraclass correlation coefficients for total GEARS scores. Face validity was assessed by a postprocedure questionnaire. Results Experts included 9 board-certified FPMRS physicians experienced in RSCP; trainees were 17 fellows. Experts practiced at 7 different institutions in the United States, and the majority (5/7) taught fellows. Trainees were from 7 institutions and in various years of training: postgraduate year (PGY) 5 (n = 6), PGY 6 (n = 5), and PGY 7 (n = 6). Experts' performances were rated significantly higher for total GEARS scores and for relevant domains of the GEARS scale. Intraclass correlation coefficient for the 3 reviewer pairs (0.96-0.99) indicated high interrater reliability. All participants "agreed/strongly agreed" that the model closely approximated live RSCP surgery and was useful for teaching and learning the procedure, indicating high face validity. Conclusions This novel, multistep simulation model demonstrated construct validity and high interrater reliability. Face validity was also established. Consequently, this RSCP model could be used for surgical training and assessment of these discrete surgical skill steps.
