The comprehensive capture of relevant details of patients is essential to accurately predict outcomes and benchmark hospital performance.1 Members of the Oncology NSQIP National Cancer Center Collaborative (ONNCC), established in 2011, were concerned that important oncology-related variables were not captured by the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP). The ONNCC began collecting 3 additional case characteristics representing greater operative complexity and risk with the aim to improve patient risk prediction and case-mix adjustment.2
