Assessing the influence of experience in pancreatic surgery: a risk-adjusted analysis using the American College of Surgeons NSQIP database.

The association between higher surgical volume and better perioperative outcomes after pancreatectomy has been extensively demonstrated. However, how different notions of experience impact outcomes of surgeons operating within high-quality scenarios remains unclear. Self-reported experience parameters from ACS-NSQIP HPB-Collaborative surgeons were merged with 2014–2016 ACS-NSQIP clinical data. The association of various experience parameters with outcomes was investigated through uni- and multivariable analyses. Hierarchical regression assessed surgeon performance. 111/151 HPB-Collaborative surgeons provided responses (73.5%). Compared to the other 532 ACS-NSQIP surgeons performing pancreatectomy, HPB-Collaborative surgeons performed 7692/16,239 of the overall pancreatectomies (47.3%), with improved outcomes of serious morbidity, pancreatic fistula, reoperation, duration of stay and readmissions. Median age of respondents was 49 years and 92.8% were fellowship-trained. Median career and annual pancreatectomy volume were 400 and 35, respectively; median annual institutional volume was 100 resections. On unadjusted analyses, several aspects of experience were associated with the outcomes studied, especially for pancreatoduodenectomy; however, none remained significant after multivariable adjustment. Surgeons' profiling showed substantial homogeneity in performance for both pancreatoduodenectomy and distal pancreatectomy. Contemporary data shows that for surgeons operating in high quality settings clinical outcomes are largely independent of indicators of greater experience. [ABSTRACT FROM AUTHOR]
