Abstract

Background: Understanding variation and heterogeneity in practice patterns allows programs to develop effective strategies to improve patient outcomes. Cytoreductive surgery is a potentially highly morbid operation that could benefit from systematic assessments directed towards quality improvement. We describe the hospital-level variation and benchmarks for programs performing cytoreductive surgery. Patients and Methods: Cytoreductive and tumor debulking operations with or without hyperthermic intraperitoneal chemotherapy performed for cancer between January 1, 2013 and June 30, 2018 were identified in the American College of Surgeons National Surgical Quality Improvement Program registry. Risk-adjusted hospital-level variation in 30-day death, serious morbidity, reoperation, readmission, and a composite of death or serious morbidity (DSM) were evaluated using hierarchical models. National Cancer Institute (NCI)-designated cancer center (NCI-CC) status was also explored. Results: A total of 6203 operations across 589 hospitals were included, of which 56 were at NCI-CCs. Unadjusted rates of death, serious morbidity, reoperation, readmission, and DSM were 1.4%, 12.9%, 3.6%, 8.6%, and 13.4%, respectively. The coefficients of variation for hospital-level performance were 4.7%, 2.1%, 4.6%, 14.4%, and 1.0% for DSM, death, serious morbidity, unplanned reoperation, and unplanned readmissions, respectively. When compared with other hospitals, NCI-CCs had better risk-adjusted 30-day mortality (median odds ratio 0.984 versus 0.998, p < 0.001), but not for the other outcomes studied. Conclusions: Hospital-level variation was modestly detected using the usual measures of perioperative outcomes. Given the increasing interest in cytoreductive surgery, we demonstrate a clear opportunity to not only improve the quality of our care but to also better improve the way quality is measured for these patients.
