N2 - Objective: To define the impact of hospital teaching status on length of stay and mortality for patients undergoing complex hepatopancreaticobiliary (HPB) surgery in the USA. Methods: Using the Nationwide Inpatient Sample, we identified 285,442 patient records that involved a liver resection, pancreatoduodenectomy, other pancreatic resection, or hepaticojejunostomy between years 2000 and 2010. Year-wise distribution of procedures at teaching and non-teaching hospitals was described. The impact of teaching status on in-hospital mortality for operations performed at hospitals in the top tertile of procedure volume was determined using multivariate logistic regression analysis. Results: A majority of patients were under 65 years of age (59.6 %), white (74.0 %), admitted on an elective basis (77.3 %), and had a low comorbidity burden (70.5 %). Ninety percent were operated upon at hospitals in the top tertile of yearly procedure volume. Among patients undergoing an operation at a hospital in the top tertile of procedure volume (>25/year), non-teaching status was associated with an increased risk of in-hospital death (OR 1.47 [1.3, 1.7]). Other factors associated with increased risk of mortality were older patient age (OR 2.52 [2.3, 2.8]), male gender (OR 1.73 [1.6, 1.9]), higher comorbidity burden (OR 1.49 [1.3, 1.7]), non-elective admission (OR 3.32 [2.9, 4.0]), and having a complication during in-hospital stay (OR 2.53 [2.2, 3.0]), while individuals with private insurance had a lower risk of in-hospital mortality (OR 0.45 [0.4, 0.5]). After controlling for other covariates, undergoing complex HPB surgery at a non-teaching hospital remained independently associated with 32 % increased odds of death as (OR 1.32, 95 % CI 1.11-1.58; P <0.001). Conclusions: Even among high-volume hospitals, patients undergoing complex HPB have better outcomes at teaching vs. non-teaching hospitals. While procedural volume is an established factor associated with surgical outcomes among patients undergoing complex HPB procedures, other hospital-level factors such as teaching status have an important impact on peri-operative outcomes.
