OBJECTIVES: This study evaluated the effect of patients'
socioeconomic status on use of coronary angiography, bypass grafting,
and angioplasty across health insurance categories.
METHODS: Multiple logistic regression was used to compute the
odds of receiving each procedure among 206 233 ischemic heart disease
patients residing in urban California zip codes from 1991 through 1993.
RESULTS: Residents of high socioeconomic status areas
were more likely (odds ratios [ORs] = 1.20-1.41) and residents of low
socioeconomic status areas were less likely (ORs = 0.79-0.84) than residents
of middle socioeconomic status areas to undergo each procedure. These
effects were common among Medicare and health maintenance organization
patients and uncommon for privately insured and uninsured patients.
CONCLUSIONS: The effect of socioeconomic status varies
across health insurance categories.
