Impact of safety-net hospital burden on achievement of textbook oncologic outcomes following resection in for stage I-IV colorectal cancer.

Abstract

Textbook oncologic outcome (TOO) is a benchmark for high-quality surgical cancer care but has not been studied at safety-net hospitals (SNH). The study sought to understand how SNH burden affects TOO achievement in colorectal cancer. The National Cancer Database was queried for colorectal cancer patients who underwent resection for stage I-III plus stage IV with liver-only metastases (2010-2019). TOO was defined as R0 resection, AJCC-compliant lymphadenectomy (>12 nodes), no prolonged LOS, no 30-day mortality/readmission, and receipt of stage-appropriate adjuvant chemotherapy. Of 487,195 patients, 66.7% achieved TOO. Lower achievement was explained by adequate lymphadenectomy (87.3%), non-prolonged LOS (76.3%), and receipt of adjuvant chemotherapy in stage III (60.3%) and IV (54.1%). Treatment at high burden hospitals (HBH, >10% Medicaid/uninsured) was a predictor of non-TOO (Stage I/II: OR 0.83, III: OR 0.86, IV: OR 0.83; all p < 0.001). Achieving TOO was associated with decreased mortality (Stage I/II: HR 0.49, III: HR 0.48, IV: HR 0.57; all p < 0.001), and HBH treatment was a predictor of mortality (Stage I/II: HR 1.09, III: HR 1.05, IV: HR 1.07; all p < 0.05). Treatment at higher SNH burden hospitals was associated with less frequent TOO achievement and increased mortality. Quality improvement targets include receipt of adjuvant chemotherapy and avoidance of prolonged LOS.
