Notes: standard errors are clustered at the individual beneficiary level. Each row represents results from a different specification using the specified dependent variable and the specified sample. All specifications control for patient age-by-sex dummies, patient race dummies, patient pay-grade dummies, previous year RVU, previous year RWP, previous year inpatient days, Charlson combordity index, and base-by-year-by-care-location fixed effects. Data are from the Military Health System Data Repository, 2003–2013.
