Hughes K, et al. - Researchers analyzed patients who were admitted with a diagnosis of critical limb ischemia from 2005 to 2014 and underwent either a major amputation or a revascularization procedure during that admission from the National (Nationwide) Inpatient Sample Database to determine the influence of lower median household income and Medicaid/no insurance status on the risk for amputation. In addition, they assessed if this occurs in a progressively linear fashion. Outcomes revealed a greater likelihood of amputation and a lower likelihood of undergoing limb-saving revascularization in correlation with lower MHI, Medicaid insurance, and uninsured status. They noted stepwise exacerbation in these disparities, such that lower income quartiles are at progressively greater risk for amputation.
