The distance to community medical care and the likelihood of hospitalization
OBJECTIVES: This study examined the influence that distance from residence to the nearest hospital had on the likelihood of hospitalization and mortality. METHODS: Hospitalizations were studied for Maine. New Hampshire, and Vermont during 1989 (adults) and for 1985 through 1989 (children) and for mortality (1989) in Medicare enrollees. RESULTS: After other known predictors of hospitalization (age, sex, bed supply, median household income, rural r…
Treatment and survival among elderly Americans with hip fractures
OBJECTIVES. This study was undertaken to examine the patterns of treatment and survival among elderly Americans with hip fracture. METHODS. A 5% national sample of Medicare claims was used to identify patients who sustained hip fractures between 1986 and 1989. In comparing treatment patterns across regions, direct standardization was used to derive age- and race-adjusted percentages. Logistic regression and Cox regression were used to examine sho…
The accuracy of Medicare's hospital claims data
BACKGROUND. Health care databases provide a widely used source of data for health care research, but their accuracy remains uncertain. We analyzed data from the 1985 National DRG Validation Study, which carefully reabstracted and reassigned ICD-9-CM diagnosis and procedure codes from a national sample of 7050 medical records, to determine whether coding accuracy had improved since the Institute of Medicine studies of the 1970s and to assess the c…
Overcoming potential pitfalls in the use of Medicare data for epidemiologic research
We used Medicare data bases and US Census data to address two questions critical to the use of Medicare files for epidemiologic research. First, we examined the degree to which the population enrolled in the Medicare program is similar to the elderly resident population of the United States, as estimated by the US Census. We found small differences in the total population estimates but substantial differences by age and race. Second, we found tha…
Risk of carotid endarterectomy in the elderly
We used the Medicare claims files to describe operative mortality for 2,089 New England residents over the age of 65 who underwent carotid endarterectomy in 1984 and 1985. For patients ages 65 to 69, the risk of death within 30 days of surgery was 1.1 percent, (95% confidence interval = 0.5, 2.1), for those ages 70 to 74, 2.8 percent (1.7, 4.4), for those ages 75 to 79, 3.2 percent (1.8, 5.2), and for those over age 80, 4.7 percent (2.3, 8.5). Ne…
Prenatal care and pregnancy outcomes during the recession
To determine whether changes in prenatal care utilization and adverse pregnancy outcomes occurred among poor residents of Washington State during the recent recession, we examined all births occurring from 1980 to 1983 to women in the poorest census tracts of the three major metropolitan counties in Washington State (N = 15,735). A comparison sample consisted of all births occurring in the highest income census tracts (N = 16,295). Because the im…
