- W4224881978 abstract "Studies have shown that Medicaid coverage is associated with higher rates of primary amputation among patients with peripheral artery disease (PAD). We sought to identify whether hospital payer makeup also influences outcomes among these patients.Patients who underwent treatment for foot complications in Texas were identified and aggregated by hospital. Hospitals were grouped by payer mix: low-income payer predominant versus high-income payer predominant. Variance analyses were used to find differences between the groups. Individual and hospital-level regression analyses were used to find associations with amputation rates.Out of 21,592 patients, 9,098 (42%) underwent amputation. They presented to 337 hospitals out of which 49 (15%) had a low-income predominant payer mix, and 109 (32%) had a high-income predominant payer mix. Patients at low-income payer predominant hospitals were more likely to present with gangrene (0.74 vs. 0.65, P < 0.01), undergo emergency admissions (0.67 vs. 0.50, P < 0.01), undergo amputation (0.53 vs. 0.42, P < 0.05), and incur higher per-day charges ($8,145 vs. $6,790, P < 0.05). At the individual level, despite risk-adjusting for disease-specific factors, amputation rate was associated with hospital payer mixes with greater proportions of Medicaid and lower proportions of commercially insured patients. At the hospital level, amputation rate was associated with higher proportion of Medicaid patients in hospital payer mix, lower hospital volumes, lower per-day charges, and higher gangrene and osteomyelitis rates (R2 = 0.30, P < 0.01).Higher proportion of Medicaid patients in a hospital payer mix is associated with an increased risk of primary amputation for PAD patients regardless of insurance coverage." @default.
