Operative duration as independent predictor of increased postoperative healthcare utilization.

OD during MIPN, MIP, and Cx is an independent predictor of increased HRU irrespective of patient comorbidities. Patients with OD > 4.5 h for MIPN, > 5 h for MIP, and > 8.5 h for Cx have 3.5-fold, 3.7-fold, and twofold increased risk of HRU, respectively.
