  1. Note: Estimates are from linear probability models with random hospital effects, adjusting for age, sex, race, dual-eligibility status, disability status, Elixhauser comorbidities, Medicare expenditures in past 180 days, urban/rural designation of hospital, Area Deprivation Index, Health Professions Shortage Area designation, teaching hospital designation, hospital ownership type, and monthly time trend
  2. Mutually exclusive TC combinations are defined such that each hospital is classified into exactly one combination
  3. *P-value indicates the significance of the difference between the coefficient estimate for the current category and the reference category in each model. Bold text indicates p < 0.05
