Medicaid and pediatric-discharge rate quartiles based on the “universe” of nonduplicate community (nonpediatric) hospitals in the 2005–2007 NIS (2,275 total hospitals). Nurse-to-patient ratio quartiles based on the number of nonmissing observations in the 2005–2007 AHA (1,384 total hospitals). State Medicaid FFS reimbursement rate index quartiles based on 49 of the 50 states (Tennessee does not have an FFS component in its Medicaid program) reported in Zuckerman, Williams, and Stockley (2009).
Quartiles combined.
There are a total of 985,896 at-risk discharges (i.e., the sample).
There are a total of 1,050 hospitals in the sample. FFS, fee-for-service.
