Notes: Age is defined at admission; non-elderly are 50–59 in HRS and 25–64 in credit reports. Insurance status is defined at the index admission for the credit report sample and in the survey wave preceding the wave which reports the index admission for the HRS sample. “Insured” denotes coverage by Medicaid or private insurance. All proportions are multiplied by 100 and the analysis is weighted to adjust for oversampling of some groups for the credit report sample and using survey weights for the HRS sample. All hospitalizations that are pregnancy related (MDC = 14) have been dropped from the credit report sample. All means are listed in percents unless otherwise noted, except for age and year of admission.

^aIn the credit report sample, black, white, other race, and Hispanic are mutually exclusive; in the HRS, “Hispanic” is asked separately from race.

^bCharges are summed and insurance type is averaged (weighted by length of stay) for people that have a single hospitalization spread across more than one unit in a hospital or more than one hospital. The standard deviation is in parentheses.

^cIn the HRS, survey waves are two years apart so we assume the index hospital admission occurs one year prior to its report. Subsequent outcomes 12 months later are therefore measured based on the survey wave reporting the index hospital admission and for 36 months later we use the survey wave subsequent to the one that reports the index admission. In the credit report data we measure outcomes 12 and 48 months later. In the HRS, mortality is mechanically zero 12 months post admission, and thus the sample conditions on survival to the next survey.

^dSubsequent insurance status for the credit report sample is defined only if they are re-admitted to the hospital.
