Complications After Inpatient Laparoscopic Cholecystectomy: Effect of Surgeon Experience, Procedure Volume, and Other Surgeon-Based Characteristics

Abstract

Background Previous studies have examined how factors such as gender, education, type of training (MD or DO), and experience of the treating surgeon affect patient outcomes. We investigated patient complications after elective laparoscopic cholecystectomy based on surgeon characteristics. Methods A Medicare database was used to identify surgeon-specific data. The main outcome measure was the adjusted complication rates (ACR) for individual surgeons as reported by the ProPublica Surgeon Scorecard. Surgeon gender, type of training, medical school rank, years since graduation, procedure volume, and teaching status of the primary hospital affiliation were assessed for any association with increased ACR using logistic regression analysis. We explored the associations among procedure volume, years of experience, and ACR using Spearman correlation. Results 1107 predominantly male (94.6%) surgeons were included. 94.4% were MDs and 34.5% were affiliated with teaching hospitals. Mean length of practice was 24 ± 9 years, and median surgeon procedure volume was 28 (IQR = 23, 37). Overall median ACR was 4.3%. Multivariate analysis demonstrated that surgeon gender ( P = .71), medical school rank, type of training ( P = .68), or hospital affiliation ( P = .77) did not have a significant impact on ACR. Increased surgeons’ years in practice (r = −.028, P = .35) and increased surgeon procedure volume (r = −.021, P = .49) were negatively associated with increased ACR. Conclusion Surgeon gender, type of training, medical school rank, or hospital affiliation had no impact on complications after laparoscopic cholecystectomy. Surgeon experience and procedure volume may have clinical implications for patient outcomes. Further studies to elucidate factors associated with surgeon quality and patient outcomes are necessary.

Does surgeon sex and anthropometry matter for tool usability in traditional laparoscopic surgery? A systematic review and meta-analysis

“…It could be speculated that there may be a cumulative effect during procedures leading to longer operative times [ 76 ]. Female surgeons are unquestionably skilled; their surgical outcomes and complication rates are the same as their counterparts [ 77 , 78 ]. However, it is still vital to consider how they are impacted by the tools they use to operate.…”
