Introduction: The aim of the current study is to assess rates of textbook outcome (TO) among Medicare beneficiaries undergoing hepatopancreatic (HP) surgery for cancer at dedicated cancer centers (DCCs) and National Cancer Institute affiliated cancer centers (NCI-CCs) versus non-DCC non-NCI hospitals.
Patients and methods: Medicare Inpatient Standard Analytic Files were utilized to identify patients undergoing HP surgery between 2013 and 2017. TO was defined as no postoperative surgical complications, no 90-day mortality, no prolonged length of hospital stay, and no 90-day readmission after discharge.
Results: Among 21,234 Medicare patients, 8.2% patients underwent surgery at DCCs whereas 32.1% underwent surgery at NCI-CCs and 59.7% underwent an operation at neither DCCs nor NCI-CCs. Although DCCs more often cared for patients with severe comorbidities [Charlson score > 5: DCCs, 1195 (68.9%), NCI-CCs, 3687 (54.1%), others, 3970 (31.3%); p < 0.001], DCCs achieved higher rates of TO compared with NCI-CCs and other US hospitals. Interestingly, DCCs were more likely to perform surgery with a minimally invasive approach versus NCI-CCs and other US hospitals (17.0%, n = 295, vs. 12.6%, n = 856 vs. 11.9%, n = 1504, p < 0.001). On multivariable analysis, patients undergoing liver surgery at DCCs had 31% and 36% higher odds of achieving TO compared with NCI-CCs and other US hospitals, respectively. Medicare expenditure was substantially lower for patients achieving TO at DCCs compared with patients who achieved a TO at NCI-CCs.
Conclusions: Even though DCCs more frequently took care of patients with high comorbidity burden, the likelihood of achieving TO for HP surgery at DCCs was higher compared with NCI-CCs and other US hospitals. The data suggest that DCCs provide higher-value surgical care for patients with HP malignancies.
