OBJECTIVES: We used 1997 Medicare data to replicate an earlier study that used data from 1986 to examine racial differences in usage of specific medical procedures or tests among elderly persons. METHODS: We used 1997 physician claims data to obtain a random sample of 5% of Medicare beneficiaries aged 65 years and older. We used this sample to study 30 procedures and tests that were analyzed in the 1986 study, as well as several new procedures that became more widely used in the early 1990s. RESULTS: Racial differences remain in the rates of use of these procedures; in general, Blacks have lower rates of use than do Whites. Between 1986 and 1997, the ratio of White to Black use moved in favor of Blacks for all but 4 of the established procedures studied. CONCLUSIONS: The White-Black gap in health care use under Medicare is narrowing. 相似文献

We assessed how commonly people in the rural South perceive racial barriers to care, the characteristics of the people among whom this perception is most common and whether this perception is associated with satisfaction with and use of health services. We analyzed telephone survey data collected in 2002-3, using weighted statistical techniques and multivariate logistic regression in analyses stratified by race. Fifty-four percent of African Americans and 23% of Whites reported that they perceive racial barriers to care in their communities. African Americans who were middle-aged or older, male, or who report being in good-to-excellent health were more likely to perceive racial barriers. Whites who were younger, less educated, and uninsured were more likely than other Whites to perceive racial barriers. For African Americans, perceptions of racial barriers were associated with lower likelihood of being satisfied with care, but not with use of preventive services. The perception of racial barriers to health care is prevalent in the rural South, especially among African Americans. The consequences of this perception may include mistrust and dissatisfaction with medical care. 相似文献

The authors analyzed ethnic/racial disparities in healthcare access and length of stay from a defined population of individuals seeking medical detoxification services at a hospital in Texas. Results indicated Blacks were more likely to be insured compared with Whites, mostly by public insurance, but this did not hold for Hispanics, who were about three times more likely to be uninsured compared with Blacks. In addition, the authors observed lower median of length of stay in the Medicaid category among Hispanics. These results can be explained by aggressive case management, sociocultural barriers, or discriminatory practices, both intentional and unintentional. 相似文献

OBJECTIVES: Minorities have worse health outcomes compared to whites, which are partially explained by racial/ethnic disparities in use of health services. Less well known, however, are whether these disparities persist among the elderly, the only group that possesses near universal health insurance coverage by Medicare, and how variation in Medicare coverage affects the receipt of preventive services. The scope of racial/ethnic disparities in the use of preventive services in the elderly was assessed, and the impact of the type of health insurance coverage on the use of preventive services was measured. METHODS: Data were derived from the 2001 California Health Interview Survey, a random-digit-dial population-based survey, collected between November 2000 and October 2001. Analysis for this project was conducted in 2004. The association of race/ethnicity and type of health insurance with receipt of preventive services was assessed using bivariate and multivariate logistic regression models. RESULTS: African Americans and Latinos were significantly less likely to be vaccinated for influenza, and Asian Americans were significantly less likely to obtain a mammogram compared to whites, while controlling for other explanatory factors. Moreover, those with Medicare plus Medicaid coverage were significantly less likely to use all four preventive services compared to those with Medicare plus private supplemental insurance. CONCLUSIONS: Despite near-universal coverage by Medicare, racial/ethnic disparities in the use of some preventive services among the elderly persist. Further research should focus on identifying potential cultural and structural barriers to receipt of preventive services aimed at designing effective intervention among high-risk groups. 相似文献

This paper provides important insights on gender differences across racial and ethnic groups in a Medicare population in terms of the quality of care received for acute myocardial infarction (AMI) and congestive heart failure (CHF) in association with diabetes or hypertension/end-stage renal disease (ESRD). Both race/ethnicity and gender are associated with differences in the diagnostic evaluation and treatment of Medicare recipients with these conditions. In the AMI group, non-Hispanic Black and Hispanic patients of both genders were less likely to receive aspirin or beta-blockers than non-Hispanic Whites. These differences persisted for Hispanic women and men even when they presented with ESRD or diabetes. Rates for smoking cessation counseling were among the lowest among non-Hispanic Blacks and Hispanics with AMI-diabetes and non-Hispanic blacks with AMI-hypertension/ESRD. Gender comparisons within racial groups for the AMI and AMI-diabetes groups show that among non-Hispanic Whites, women were less likely to receive aspirin and beta-blockers. No gender differences were noted among non-Hispanic Black and Hispanic Medicare recipients. In the CHF group, Hispanics were the racial/ethnic group least likely to have an assessment of left ventricular function (LVF), even if they had diabetes and had lower rates of angiotensin-converting enzyme inhibitor therapy or even if they had combined CHF-hypertension/ESRD. Gender comparisons in both the CHF and CHF-hypertension/ESRD groups show that non-Hispanic White women were less likely to have an LVF assessment than non-Hispanic White men. Among all subjects, having comorbidities with AMI was not associated with higher markers of quality cardiovascular care. Closing the many gaps in cardiovascular care must target the specific needs of women and men across racial and ethnic groups. 相似文献

OBJECTIVES. The purpose of this study was to determine whether women's sociodemographic characteristics are independently associated with cesarean delivery. METHODS. A retrospective review was conducted of hospital discharge data for singleton first births in California in 1991. RESULTS. After insurance and personal, community, medical, and hospital characteristics had been controlled, Blacks were 24% more likely to undergo cesarean delivery than Whites; only among low-birthweight and county hospital births were Blacks not at a significantly elevated risk. Among women who resided in substantially non-English-speaking communities, who delivered high-birthweight babies, or who gave birth at for-profit hospitals, cesarean delivery appeared to be more likely among non-Whites and was over 40% more likely among Blacks than among Whites. CONCLUSIONS. The findings cannot establish causation, but the significant racial/ethnic disparities in delivery mode, despite adjustment for social, economic, medical, and hospital factors, suggest inappropriate influences on clinical decision making that would not be addressed by changes in reimbursement. If practice variations among providers are involved, de facto racial differences in access to optimal care may be indicated. The role of provider and patient attitudes and expectations in the observed racial/ethnic differentials should also be explored. 相似文献

The objective of this research is to examine the influence of income and type of insurance coverage on the use of health services among the nonmetropolitan elderly. A model of health services utilization is used as the foundation for examining this issue with data from a telephone survey of a randomly selected sample of residents from four nonmetropolitan counties in Pennsylvania. Results indicated that those elders with Medicaid coverage were less likely to visit a doctor than respondents with private insurance or Medicare only, even after controlling for income and other relevant factors. Further, lower income respondents with Medicare were less likely to visit the dentist than those with private insurance (Medicare does not cover dental care). In contrast, neither income nor insurance predicted hospital use. As such, the health and dental care needs of many lower income nonmetropolitan elders may potentially be going unmet. In general, findings highlight the continued relevance of economic barriers to the use of such services among the nonmetropolitan elderly. 相似文献

OBJECTIVES. The purpose of this study was to identify the role of race in seeking and receipt of care for symptoms of coronary heart disease. METHODS. Data on medical care, sociodemographic characteristics, symptoms, risk factors, income, and insurance were collected in a telephone interview for a random sample of 2030 Black and White adults in inner-city Boston. Rates of care-seeking for symptoms, amounts of delay in seeking care, and rates of receipt of care were compared for Blacks and Whites after adjustment for other characteristics. RESULTS. Before and after adjustment for other factors, Blacks and Whites were equally likely to seek care. Average delay time was shorter for Blacks, particularly Black women. With the exception of a lower rate of referral to cardiologists among Blacks, receipt of care was similar for Blacks and Whites who sought medical attention for symptoms. CONCLUSIONS. In an urban population of Blacks and Whites who were similar in socioeconomic status and access to medical care, there were few racial differences in coronary heart disease-related care patterns. 相似文献

Racial and ethnic differences in the use of invasive cardiac procedures among cardiac patients in Los Angeles County, 1986 through 1988. 总被引:5,自引:2,他引:3
OBJECTIVES. The purpose of the study was to compare use of invasive cardiovascular procedures among Latino, Asian, African-American, and White patients. METHODS. In a cross-sectional study of hospital discharge data, multiple logistic regression was used to model use of coronary artery angiography, bypass graft surgery, and angioplasty among adult Los Angeles County residents discharged from California hospitals between 1986 and 1988 with primary diagnoses consistent with possible ischemic heart disease. RESULTS. After potential demographic, socioeconomic, and clinical confounders, including hospital procedure volume, were controlled, Latinos were less likely than Whites to undergo angiography (odds ratio [OR] = 0.90) and bypass graft surgery (OR = 0.87). African Americans were less likely to receive bypass graft surgery (OR = 0.62) and angioplasty (OR = 0.80). Asians were as likely as Whites to receive each procedure. The impact of adjustment for hospital procedure volume was greater for Latinos and Asians than for African Americans. CONCLUSIONS. Administrative data suggest that disparities in use of invasive cardiovascular procedures are not limited to African Americans. Hospital procedure volume appears to be an important factor related to such disparities. The causes of racial/ethnic differences in reported procedure rates remain unclear. 相似文献

This study examines the relationship between socioeconomic advantage and the likelihood of receiving specialty care in a nationally representative sample of older Americans participating in fee-for-service Medicare. In 1992, 62.9 percent of Americans aged 65 and older visited a specialist physician at least once. Being white, having more education, and having a higher income were each independently associated with a higher likelihood of visiting a specialist. Having insurance to supplement basic Medicare coverage was also independently associated with an increased likelihood of visiting a specialist; disadvantaged elders are less likely to have such supplemental insurance. Therefore, based both upon socioeconomic disadvantage and a lack of insurance to supplement the basic Medicare benefit, black, less educated and low-income elders are less likely to receive specialty services under fee-for-service Medicare. As the program evolves, it will be important to continue to monitor access to specialty care in vulnerable, socioeconomically disadvantaged populations. 相似文献

This paper examines racial variation in quality of and access to care experienced by elderly persons enrolled in Medicare+Choice plans. We used eight individual-level Health Plan Employer Data and Information Set (HEDIS) measures to compare whites with blacks, Asians, Hispanics, and Native Americans. Across all measures, black enrollees received lower-quality care. Hispanics and Native Americans were less likely to receive some types of care but were as likely or more likely to receive other types of care. Asians received equal or better care for all measures. It is important that studies of health care quality include all racial subgroups since the black/white patterns may not apply. 相似文献

OBJECTIVES: Racial differences in access to cardiac artery bypass graft (CABG) surgery are well documented. This study extends the literature by examining racial differences in access to high-quality cardiac surgeons. METHODS: The analyses included 11,296 CABG surgeries in New York State in 1996. Regression techniques were used to identify significant associations between a patient's race, health maintenance organization (HMO) enrollment, and the quality of the surgeon performing the surgery, measured by the surgeon's risk-adjusted mortality rate (RAMR). RESULTS: Non-Whites were more likely than Whites to have access to surgeons of higher RAMR, by 11.7% among HMO enrollees (1-tailed P < .1) and by 5.4% among fee-for-service enrollees (1-tailed P < .05). CONCLUSIONS: Even when racial minorities do gain access to CABG services, they are more likely that non-Whites to receive care from lower-quality providers. 相似文献

OBJECTIVES: Considerable differences in prevalence of diabetes and management of the disease exist among racial/ethnic groups. We examined the relationship between race/ethnicity and hospital readmissions for diabetes-related conditions. METHODS: Nonmaternal adult patients with Medicare, Medicaid, or private insurance coverage hospitalized for diabetes-related conditions in 5 states were identified from the 1999 State Inpatient Databases of the Healthcare Cost and Utilization Project. Racial/ethnic differences in the likelihood of readmission were estimated by logistic regression with adjustment for patient demographic, clinical, and socioeconomic characteristics and hospital attributes. RESULTS: The risk-adjusted likelihood of 180-day readmission was significantly lower for non-Hispanic Whites than for Hispanics across all 3 payers or for non-Hispanic Blacks among Medicare enrollees. Within each payer, Hispanics from low-income communities had the highest risk of readmission. Among Medicare beneficiaries, Blacks and Hispanics had higher percentages of readmission for acute complications and microvascular disease, while Whites had higher percentages of readmission for macrovascular conditions. CONCLUSIONS: Racial/ethnic disparities are more evident in 180-day than in 30-day readmission rates, and greatest among the Medicare population. Readmission diagnoses vary by race/ethnicity, with Blacks and Hispanics at higher risk for those complications more likely preventable with effective postdischarge care. 相似文献

OBJECTIVES: This study examined racial/ethnic disparities in mental health service access and use at different poverty levels. METHODS: We compared demographic and clinical characteristics and service use patterns of Whites, Blacks, Hispanics, and Asians living in low-poverty and high-poverty areas. Logistic regression models were used to assess service use patterns of minority racial/ethnic groups compared with Whites in different poverty areas. RESULTS: Residence in a poverty neighborhood moderates the relationship between race/ethnicity and mental health service access and use. Disparities in using emergency and inpatient services and having coercive referrals were more evident in low-poverty than in high-poverty areas. CONCLUSIONS: Neighborhood poverty is a key to understanding racial/ethnic disparities in the use of mental health services. 相似文献

OBJECTIVE: To examine explanations of differences in utilization rates of a newly reintroduced technique - off-pump coronary artery bypass grafting (CABG) - between racial minorities and Whites. METHOD: The study was based on 15,313 CABG patients in the New York State Cardiac Surgery Reporting System covering all cardiac surgeons providing off-pump CABG in New York State. We estimated cross sectional, random effect regression models predicting the probability of off-pump versus on-pump surgery. RESULTS: Thirty one percent of Blacks, 20.7% of other races, and 23% of Whites underwent off-pump CABG (P <0.0001). The higher rates for Blacks arose mostly from being treated by surgeons performing only a few off-pump procedures rather than from surgeons performing many off-pump surgeries. After adjusting for clinical characteristics and coronary anatomy, Blacks treated by surgeons with low volume off-pump procedures were 1.9 times (P <0.01) more likely to have off-pump surgery compared with Whites treated by the same surgeons. There were no significant differences between Blacks and Whites treated by high volume surgeons. CONCLUSIONS: These findings suggest that surgeons who are inexperienced with the off-pump techniques are more likely to perform this surgery on Black patients. Further research should examine potential explanations and the agenda addressing racial disparities should be expanded to address issues of treatment decisions. 相似文献

To address the widening disparity between Whites and non-Whites for influenza vaccination rates, this study employed the Health
Belief Model to examine these rates in five racial ethnic groups (White, Latino, African American, Filipino American, and
Japanese American) to identify modifiable determinants of vaccination by race/ethnicity. A 2004 telephone survey of parishioners
of faith-based congregations aged 50–75 years in Los Angeles and Honolulu assessed influenza vaccination rate, perceived susceptibility
to influenza, perceived severity of illness, and the self-reported main barrier to influenza vaccination. Logistic regression
models for each race/ethnic group predicting vaccination dependent upon perceived susceptibility to influenza, perceived severity
of illness, and sociodemographic characteristics were estimated. Model parameters were used to generate standardized predictions
of vaccination rates by race/ethnic group. In the multivariate models, Whites and African Americans who were very concerned
about getting the flu were significantly more likely to be vaccinated (96% and 91%, respectively), compared with those who
were not concerned (45% and 33%). However, vaccination rates among Latinos who were very concerned about getting the flu (54%),
although significantly higher than Latinos who were not concerned (34%), were lower than for Whites and African Americans.
Examination of the main barriers to vaccination revealed that Latinos were more likely to report access and cost barriers,
while African Americans were more likely to raise issues of mistrust such as concern that the vaccine causes influenza. Distinct
barriers to influenza vaccination exist among racial/ethnic groups. Vaccination programs may benefit from addressing these
specific and unique concerns. 相似文献

This paper investigates whether managed care ameliorates or aggravates ethnic and racial health care disparities in Medicare. First, we analyze the choice of type of insurance made by Medicare enrollees to see if minorities are more likely to choose the managed care alternative. Second, we study the differential effect of managed care on disparities using several measures of access, use and cost of services. Both analyses are conducted on two independent data sets, the Medicare Current Beneficiary Survey and the National Health Interview Survey. We conclude that relative to Whites, minorities are at least as well off -- in terms of benefits and costs -- in Medicare managed care as in Medicare traditional indemnity plans. 相似文献

OBJECTIVE: To explore three potential causes of racial/ethnic differences in influenza vaccination rates in the elderly: (1) resistant attitudes and beliefs regarding vaccination by African-American and Hispanic Medicare beneficiaries, (2) poor access to care during influenza vaccination weeks, and (3) discriminatory behavior by providers. DATA SOURCES: Medicare beneficiaries who responded to both the 1995 and 1996 Medicare Current Beneficiary Survey (MCBS) (n=6,746). STUDY DESIGN: We combined survey information from the MCBS with Medicare claims. We measured resistance to vaccination by self-reported reasons for not receiving vaccination, access to care by claims submitted during vaccination weeks, and discrimination by racial differences in vaccinations among beneficiaries who visited the same providers during vaccination weeks. PRINCIPAL FINDINGS: White beneficiaries (66.6 percent) were more likely to self-report having received vaccination than were African Americans (43.3 percent) or Hispanics (52.5 percent). Resistance to vaccination plays a role in low vaccination rates of African-American (-11.8 percentage points), but not Hispanic beneficiaries. Unequal access accounts for <2 percent of the disparity. Minority beneficiaries remained unvaccinated despite having medical encounters with their usual providers on days when those same providers were administering vaccinations to white beneficiaries. This disparity is attributable not to provider discrimination but to a 1.6-5 x higher likelihood of white beneficiaries initiating encounters for the purpose of receiving vaccination. CONCLUSION: Disparities in access to care and provider discrimination play little role in explaining racial/ethnic disparities in influenza vaccination. Eliminating missed opportunities for vaccination in 1995 would have raised vaccination rates in three racial/ethnic groups to the Healthy People 2000 goal of 60 percent vaccination. 相似文献

Explaining racial disparities in incidence of and survival from out-of-hospital cardiac arrest 总被引:1,自引:0,他引:1

A prospective observational study of 4,653 consecutive cases of out-of-hospital cardiac arrest (OOHCA) occurring in New York City from April 1, 2002, to March 31, 2003, was used to assess racial/ethnic differences in the incidence of OOHCA and 30-day survival after hospital discharge among OOHCA patients. The age-adjusted incidence of OOHCA per 10,000 adults was higher among Blacks than among persons in other racial/ethnic groups, and age-adjusted survival from OOHCA was higher among Whites compared with other groups. In analyses restricted to 3,891 patients for whom complete data on all variables were available, the age-adjusted relative odds of survival from OOHCA among Blacks were 0.4 (95% confidence interval: 0.2, 0.7) as compared with Whites. A full multivariable model accounting for demographic factors, prior functional status, initial cardiac rhythm, and characteristics of the OOHCA event explained approximately 41 percent of the lower age-adjusted survival among Blacks. The lower prevalence of ventricular fibrillation as the initial cardiac rhythm among Blacks relative to Whites was the primary contributor. A combination of factors probably accounts for racial/ethnic disparities in OOHCA survival. Previously hypothesized factors such as delays in emergency medical service response or differences in the likelihood of receipt of cardiopulmonary resuscitation did not appear to be substantial contributors to these racial/ethnic disparities. 相似文献

BACKGROUND: We examined the effect of sociodemographic factors on the receipt of mammography, colorectal cancer screening, and influenza vaccinations by women enrolled in two Medicare+Choice health plans. METHODS: Administrative and survey data for 2,698 female health plan members was analyzed using multivariate logistic and ordinal logistic regression to assess the effects of enrollee characteristics on use of preventive services. RESULTS: Age, race and wealth were associated with the receipt of one or more preventive services. Older women were less likely to receive mammograms, wealthier women were more likely to receive mammograms and CRC screening, and Black women were more likely to receive CRC screening but less likely to receive influenza vaccinations. Wealthier women received a greater number of preventive services, other things equal, while older women received fewer preventive services. CONCLUSIONS: Race and wealth continue to be important factors in the receipt of preventive services by elderly women, though not always consistent with historical trends. Medicare+Choice plans should consider strategies to further reduce racial and wealth disparities in the use of preventive services. 相似文献
