Do Cancer Centers Need to Assess Quality and Outcomes? Introducing a Customized ACS-NSQIP for Oncology (Onc-Nsqip).

475 Background: To identify quality improvement opportunities, hospitals can use ACS NSQIP to compare their risk-adjusted performance to other hospitals. However, Cancer Centers have few opportunities to compare their outcomes to similar hospitals for oncologic operations. Our objective was to develop an oncology-specific version of ACS NSQIP (Onc-NSQIP) and determine whether it could be useful for Cancer Centers. Methods: From ACS-NSQIP (2006-2009), patients undergoing major colorectal (n=34,858; 221 hospitals) and pancreatic (n=7,667; 65 hospitals) as well as esophageal, gastric, and soft tissue operations for malignancy were identified. Risk-adjusted postoperative outcomes were assessed with regression models adjusting for demographics, comorbidities, and operative procedure. Relative rankings of NCI-designated Comprehensive Cancer Centers in ACS NSQIP among the other ACS NSQIP hospitals were compared. Results: Cancer Center outcomes varied widely for colorectal and pancreas. For overall colorectal morbidity, Cancer Centers were ranked in the top third (n=4), middle third (n=7), and bottom third (n=10). For colorectal 30-day mortality, Cancer Centers were ranked in the top (n=14), middle (n=3), and bottom third (n=4). For overall pancreatic morbidity, Cancer Centers were ranked in the top (n=5), middle (n=7), and bottom third (n=7). For pancreatic 30-day mortality, Cancer Centers were ranked in the top (n=5), middle (n=6), and bottom third (n=8). Similar results were observed for colorectal and pancreas for DVT/PE, SSI, reoperation, and length of stay. Onc-NSQIP models were comparable to standard ACS NSQIP models. At least some Cancer Centers were statistical outliers for most outcomes (P<0.05). Results were similar for other malignancies. Conclusions: Cancer Center outcomes varied as much as other ACS NSQIP hospitals, demonstrating need for quality assessment. Without standardized risk-adjusted outcomes comparisons, Cancer Centers cannot accurately assess their outcomes to identify quality improvement targets. ACS NSQIP's new platform allows customization so hospitals can compare surgical oncology-specific risk-adjusted processes and outcomes. No significant financial relationships to disclose.
