Why the study?
Does socioeconomic status affect the use of invasive cardiovascular procedures across health insurance categories in patients with ischemic heart disease?
Does socioeconomic status affect the use of invasive cardiovascular procedures across health insurance categories in patients with ischemic heart disease?
Socioeconomic disparities in the utilization of invasive cardiovascular procedures exist but vary significantly depending on the patient's health insurance category.
Answers are grounded in this paper and cite their sources.
SES disparities in invasive procedure use warrant monitoring but should not yet alter practice; leaves open insurance-specific mechanisms and equity interventions.
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.
