RESUMEN
OBJECTIVE: To assess the relative contributions of individual insurance status and hospital payer mix (safety net status) to quality of care and survival for patients with cervical cancer. METHODS: We used the National Cancer Database to identify patients with cervical cancer diagnosed from 2004 to 2017. Patients were classified by insurance (uninsured/Medicaid/private/Medicare/other) and hospitals were grouped into quartiles based on the proportion of uninsured/Medicaid patients (payer mix) (top quartile defined as safety-net hospital (SNHs) and lowest as Q1 hospitals). Quality-of-care was assessed by adherence to evidence-based metrics. Individual contributions of insurance status and payer mix to survival was assessed with a proportional hazards Cox model. RESULTS: A total of 124,339 patients including 11,338 uninsured (9.1%) and 27,281 Medicaid (21.9%) recipients treated at 1156 hospitals were identified. Quality-of-care was not significantly different across hospital quartiles. Adjusting for patients' clinical/demographic characteristics, treatment at a SNH was associated with a 14% higher mortality (HR = 1.14; 95% CL, 1.08-1.20) than at Q1 hospitals. Testing for individual insurance, uninsured patients had 32% increased mortality (HR = 1.32; 95% CI,1.26-1.38) and Medicaid recipients 40% increased (HR = 1.40; 95%CI,1.35-1.44) compared to privately insured patients. Examining both payer mix and insurance, only individual insurance retained a significant impact on mortality. CONCLUSIONS: Individual insurance may be a more important predictor of survival than site-of-care and hospital payer mix for women with cervical cancer. There is substantial variation in outcomes within hospitals based on individual insurance, regardless of hospital payer mix.
