To calculate the adjusted differences, we ran OLS model with corresponding SNF characteristics as outcome variable onto demographic characteristics, education, Elixhauser and Deyo indexes, length of stay at the hospital (listed in Table1), hospital admission DRG, and origin ZIP code fixed effects. Chain membership, profit status, and hospital association are binary variables. The rest are continuous variables.
CNA, certified nursing assistant; FTE, full-time equivalent; LPN, licensed practical nurse; RN, registered nurse; RUGS, resource utilization group; SNF, skilled nursing facility.
