  1. For-profit hospitals were matched to nonprofit hospitals on teaching hospital status, geographical region (West, South, Midwest, and Northeast), and size. Hospitals serving regions with median household income under $30,000 were classified as low income, hospitals serving regions with median household income between $30,000 and $79,999 were classified as middle income, and hospitals serving regions with median household income above $79,999 were classified as high income. Estimates were calculated using a linear mixed-effects model with charity care as percent of total expenses as the outcome and ownership status as the independent variable with random intercepts for the matched group to allow for correlation within matches.
