ObjectiveTo characterize the association between type of fellowship training and patient outcomes following hepatopancreatic (HP) surgery across different surgeon career stages using a national representative cohort of Medicare beneficiaries.BackgroundThe current state of training in HPB surgery in North America is defined through three main pathways: the Complex General Surgical Oncology (CGSO), the Americas HPB Association fellowship, and the American Society of Transplant surgeons fellowship. Each pathway offers a unique perspective on HPB surgery with different number of training years, yet outcomes of graduates performing HP surgery relative to type of fellowship training have not been defined.MethodsMedicare claims were used to identify patients who underwent HP surgery for cancer between 2016-2021. The association of textbook outcomes (TO), defined as no postoperative complications, no prolonged LOS, no 90-day mortality and no 90-day readmission, relative to different fellowship pathways was examined.ResultsOverall, 15,411 cancer operations (pancreatectomy: 11,003, 71.4%; hepatectomy: 4,408, 28.6%) were performed by 1,030 HPB surgeons. A total of 9,390 patients (60.9%) were operated on by a CGSO/SONC graduate, 2,315 patients (15.0%) by an HPB fellowship graduate and 3,706 (24.1%) by a transplant fellowship graduate. Patients who were operated on by an HPB fellowship graduate more frequently had a higher Charlson score (>5: 44.8% vs. 38.1%) and more frequently were operated on an urgent basis (7.7% vs. 6.1%) compared with individuals treated by CGSO/SONC graduates. After adjusting for patient, procedural, hospital, and surgeon related factors, the likelihood of TO following an HP operation by an HPB fellowship graduate was 47.7% versus 45.2% among CGSO (% difference 2.7%) and 42.8% among transplant fellowship graduates (% difference 4.9%, P=0.01). While the probability of TO was higher among surgeons having completed a dedicated HPB fellowship during early (1-7th year of independent practice, P=0.032) and middle (8-14th year, P<0.001) career stages, the probability of TO did not differ based on fellowship type among late career surgeons (>15th year, P=0.257).ConclusionsAchievement of TO following an HP procedure was higher among surgeons who had completed a dedicated HPB fellowship, especially during early and middle career stages. Further efforts should be made to enhance HP surgery exposure and training for CGSO fellows interested in a career in HPB surgery.Copyright © 2024 Wolters Kluwer Health, Inc. All rights reserved.
