This study demonstrates statistical improvement in operative time after the first 20 cases for a single surgeon. This information could be used to establish criteria for training surgeons.
The American College of Obstetricians and Gynecologists and the American Association of Gynecologic Laparoscopists confirm advantages of conventional minimally invasive surgery over laparotomy for benign gynecological procedures; however, adoption remains low for the general gynecologist. A systematic search for gynecology publications was performed using Medline and Scopus. Available data on adoption rates and perioperative outcomes for hysterectomy, myomectomy, sacrocolpopexy, and endometriosis were reviewed. Robotic assistance may provide an improved rate of minimally invasive surgery adoption with equivalent perioperative outcomes to that of conventional techniques. Accessibility and cost remain controversial. Formal training programs are being created to address these issues.
Objective
Objective structured assessments of technical skills (OSATS) have been developed to measure the skill of surgical trainees. Our aim was to develop an OSATS specifically for trainees learning robotic surgery.
Study Design
This is a multi-institutional study in eight academic training programs. We created an assessment form to evaluate robotic surgical skill through five inanimate exercises. Obstetrics/gynecology, general surgery, and urology residents, fellows, and faculty completed five robotic exercises on a standard training model. Study sessions were recorded and randomly assigned to three blinded judges who scored performance using the assessment form. Construct validity was evaluated by comparing scores between participants with different levels of surgical experience; inter- and intra-rater reliability were also assessed.
Results
We evaluated 83 residents, 9 fellows, and 13 faculty, totaling 105 participants; 88 (84%) were from obstetrics/gynecology. Our assessment form demonstrated construct validity, with faculty and fellows performing significantly better than residents (mean scores: 89 ± 8 faculty; 74 ± 17 fellows; 59 ± 22 residents, p<0.01). In addition, participants with more robotic console experience scored significantly higher than those with fewer prior console surgeries (p<0.01). R-OSATS demonstrated good inter-rater reliability across all five drills (mean Cronbach's α: 0.79 ± 0.02). Intra-rater reliability was also high (mean Spearman's correlation: 0.91 ± 0.11).
Conclusions
We developed an assessment form for robotic surgical skill that demonstrates construct validity, inter- and intra-rater reliability. When paired with standardized robotic skill drills this form may be useful to distinguish between levels of trainee performance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
