Lower rates of invasive cardiac procedures have been reported for blacks and women than for white men. However, few studies have adjusted for differences in the type of hospital of admission, insurance status, and disease severity. SETTING, DESIGN, AND PARTICIPANTS: Data from the National Hospital Discharge Survey were used to investigate race and sex differences in rates of cardiac catheterization, percutaneous transluminal coronary angioplasty, and coronary artery bypass surgery among 10,348 persons hospitalized for acute myocardial infarction.
White men consistently had the highest procedure rates, followed by white women, black men, and black women. After matching for the hospital of admission and adjusting for age, in-hospital mortality, health insurance, and hospital transfer rates (with white men as the referent), the odds ratios for cardiac catheterization were 0.67 (95% confidence interval [CI], 0.51 to 0.87) for black men, 0.72 (95% CI, 0.63 to 0.83) for white women, and 0.50 (95% CI, 0.37 to 0.68) for black women. Similar race-sex differences were noted for percutaneous transluminal coronary angioplasty and coronary artery bypass surgery.
Race and sex differentials in the rates of invasive cardiac procedures remained despite matching for the hospital of admission and controlling for other factors that influence procedure rates, suggesting that the race and sex of the patient influence the use of these procedures.

- "However, health need did not explain the other racial/ethnic differences in functional disability found in this study. Although some studies have found that minority group members enter the health care system in worse health than Whites (Ebell et al., 1995; Gourin & Podolsky, 2006; Horner et al., 1991), other studies have argued that disease severity does not explain racial/ethnic differences in health outcomes (Giles et al., 1995; McBean et al., 1994; Schneider et al., 2002). We were unable to investigate this possibility directly because there are no data on the severity of respondents' medical conditions in the HRS. "

ABSTRACT: The purpose of this study was to examine racial/ethnic differences in the relationship between functional disability and the use of health care services in a nationally representative sample of older adults by using the Andersen behavioral model of health services utilization.
The study used 12 years of longitudinal data from the Health and Retirement Study (1992-2004), a nationally representative sample of community-dwelling adults older than 50 in 1992 (N = 8,947). Nonlinear multilevel models used self-reported health care service utilization (physician visits and hospital admissions) to predict racial/ethnic differences in disability (activities of daily living and mobility limitations). The models also evaluated the roles of other predisposing (age and gender), health need (medical conditions and self-rated health), and enabling factors (health insurance, education, income, and wealth).
Blacks and Latinos utilizing physician visits and hospital admissions were associated with significantly more activity of daily living disability than Whites (p <.001). Blacks utilizing physician visits (p <.001) and hospital admissions (p <.05) and Latinos utilizing hospital admissions (p <.05) were associated with more mobility disability than Whites. Other predisposing, health need, and enabling factors did not account for these racial/ethnic differences.
Nationally, health care use for Blacks and Latinos was associated with more disabilities than for Whites after we accounted for predisposing, health need, and enabling factors. The findings suggest that improving health care quality for all Americans may supersede equal access to health care for reducing ethnic and racial disparities in functional health.

- "In fact, the gap in the revascularization rates between the four groups of patients at index hospitalization benefits patients living at less than 32 km from a SCC. A frequent explanation put forward in the literature to account for use of invasive cardiac procedures is accessibility to facilities performing such procedures . "

ABSTRACT: Early access to revascularization procedures is known to be related to a more favorable outcome in myocardial infarction (MI) patients, but access to specialized care varies widely amongst the population. We aim to test if the early gap found in the revascularization rates, according to distance between patients' location and the closest specialized cardiology center (SCC), remains on a long term basis.
We conducted a population-based cohort study using data from the Quebec's hospital discharge register (MED-ECHO). The study population includes all patients 25 years and older living in the province of Quebec, who were hospitalized for a MI in 1999 with a follow up time of one year after the index hospitalization. The main variable is revascularization (percutaneous transluminal coronary angioplasty or a coronary artery bypass graft). The population is divided in four groups depending how close they are from a SCC (< 32 km, 32-64 km, 64-105 km and > or = 105 km). Revascularization rates are adjusted for age and sex.
The study population includes 11,802 individuals, 66% are men. The one-year incidence rate of MI is 244 individuals per 100,000 inhabitants. At index hospitalization, a significant gap is found between patients living close (< 32 km) to a SCC and patients living farther (> or = 32 km). During the first year, a gap reduction can be observed but only for patients living at an intermediate distance from the specialized center (64-105 km).
The gap observed in revascularization rates at the index hospitalization for MI is in favour of patients living closer (< 32 km) to a SCC. This gap remains unchanged over the first year after an MI except for patients living between 64 and 105 km, where a closing of the gap can be noticed.

- "Studies of racial and ethnic differences in cardiovascular care provide some of the most convincing evidence of healthcare disparities. The most rigorous studies in this area assess both potential underuse and overuse of services and appropriateness of care by controlling for disease severity using well-established clinical and diagnostic criteria (e.g., Schneider et al., 2001; Ayanian et al., 1993; Allison et al., 1996; Weitzman et al., 1997) or matched patient controls (Giles et al., 1995). Several studies, for example, have assessed differences in treatment regimen following coronary angiography, a key diagnostic procedure. "

ABSTRACT: Racial and ethnic minorities tend to receive a lower quality of healthcare than non-minorities, even when access-related factors, such as patients' insurance status and income, are controlled. The sources of these disparities are complex, are rooted in historic and contemporary inequities, and involve many participants at several levels, including health systems, their administrative and bureaucratic processes, utilization managers, healthcare professionals, and patients. Consistent with the charge, the study committee focused part of its analysis on the clinical encounter itself, and found evidence that stereotyping, biases, and uncertainty on the part of healthcare providers can all contribute to unequal treatment. The conditions in which many clinical encounters take place- characterized by high time pressure, cognitive complexity, and pressures for cost-containment—may enhance the likelihood that these processes will result in care poorly matched to minority patients' needs. Minorities may experience a range of other barriers to accessing care, even when insured at the same level as whites, including barriers of language, geography, and cultural familiarity. Further, financial and institutional arrangements of health systems, as well as the legal, regulatory, and policy environment in which they operate, may have disparate and negative effects on minorities' ability to attain quality care. A comprehensive, multi-level strategy is needed to eliminate these disparities. Broad sectors—including healthcare providers, their patients, payors, health plan purchasers, and society at large—should be made aware of the healthcare gap between racial and ethnic groups in the United
