Abstract

Objective: We sought to identify postoperative complications with the greatest impact on patient-centric outcomes to serve as high yield QI targets in ovarian cancer (OC) surgery. Methods: Women undergoing complex CRS (defined as cytoreductive surgery with colon resection) for OC between January 1, 2012 and 12/31/2016 were identified from the National Surgical Quality Improvement Program (NSQIP) database. We determined the population attributable fraction (PAF) to quantify the contribution of each major complication towards adverse outcomes. PAF represents the burden of adverse outcomes that could be eliminated if the corresponding complication was prevented. Organ space surgical site infection (SSI) was used as a surrogate for anastomotic leak (AL). Results: A total of 1434 women met inclusion criteria. Any adverse clinical outcome (composite of death, reoperation, or end organ dysfunction) occurred in 9.1% of women, and AL was the largest contributor to adverse clinical outcomes [PAF = 33.4% (95%CI: 22.3%–45.6%)]. The rates of increased resource utilization were as follows; prolonged hospitalization in 23.7%, non-home discharge in 10.7% and unplanned readmission in 14.8% of women. AL was the largest contributor to prolonged hospitalizations [PAF = 75.7% (95%CI: 51.4%–90.0%)] and readmissions [PAF = 17.1% (95%CI: 11.5%–22.6%)]; while transfusion was the largest contributor to non-home discharge [PAF = 22.8% (95%CI: 0.7%–42.4%)]. By comparison, the impact of other complications, including those targeted by the Surgical Care Improvement Project (SCIP), such as incisional SSI, venous thromboembolism, myocardial infarction, and urinary infection, was small. Conclusions: Anastomotic leak is the largest contributor to adverse clinical outcomes and increased resource utilization after complex cytoreductive surgery. Quality improvement efforts to reduce AL and its impact should be of highest priority in OC surgery.
