ABSTRACT:We describe the racial segregation in U.S. nursing homes and its relationship to racial disparities in the quality of care. Nursing homes remain relatively segregated, roughly mirroring the residential segregation within metropolitan areas. As a result, blacks are much more likely than whites to be located in nursing homes that have serious deficiencies, lower staffing ratios, and greater financial vulnerability. Changing health care providers' behavior will not be sufficient to eliminate disparities in medical treatment in nursing homes. Persistent segregation among homes poses a substantial barrier to progress. [Health Affairs 26, no. 5 (2007): 1448-1458 10.1377/hlthaff.26.5.1448 T h e e f f e c t o f r ac i a l s e g r e gat i o n on disparities in medical treatment has only recently received attention from researchers. This research has shown that blacks are more likely than whites to seek care from hospitals that have fewer resources in terms of up-to-date technology.1 They are also more likely to receive care at hospitals with higher surgical mortality rates, undergo cardiovascular procedures at lower-volume hospitals, and receive maternity services at hospitals that have higher risk-adjusted neonatal mortality rates for both black and white infants.2 Blacks are also more likely to receive their primary care from physicians who tend to be less well trained than from physicians who primarily treat whites; have less access than whites to important clinical resources such as high-quality subspecialists, diagnostic imaging, and nonemergency admissions to hospitals; and report less control over their work, more time pressure, and higher rates of burnout than their white peers.3 These differences in primary care are reflected in missed opportunities among blacks for higher rates of early intervention with breast and prostate cancer treatment. 4 A tiered system of nursing home care that concentrates blacks in marginal-quality nursing homes also appears to exist. 5 n Historical background. Historically, segregation and discrimination in access to higher-quality nursing homes in the United States have never been systematically addressed. Before Medicare and Medicaid were implemented in 1966, nursing homes in the South were totally segregated by Jim Crow laws and in the North almost as much by patterns of use and admission practices. Racial segregation also took place within homes through separate floors and wings; it has persisted in some homes through similar segregation by payer status. In the past, blacks have had far more limited access to nursing home care than whites have had. In 1963, nursing home use by nonwhites over age sixty-five was 39 percent that of whites.6 A decade later, well after the implementation of Medicare and Medicaid, use of nursing homes by elderly blacks was still only 47 percent that of elderly whites. n Early noncompliance with the law. Title VI of the 1964 Civil Rights Act prohibits segregation and other forms of discrimination in any organization receiving federal funds. In s...
