Perceived Discrimination and Use of Preventive Health Services

BACKGROUND: Little is known about the relation between perceptions of health care discrimination and use of health services. OBJECTIVES: To determine the prevalence of perceived discrimination in health care, its association with use of preventive services, and the contribution of perceived discrimination to disparities in these services by race/ethnicity, gender, and insurance status. DESIGN, SETTING, AND PARTICIPANTS: Cross-sectional study of 54,968 respondents to the 2001 California Health Interview Survey. MEASUREMENTS: Subjects were asked about experience with discrimination in receiving health care and use of 6 preventive health services, all within the previous 12 months. METHODS: We used multivariate logistic regression with propensity-score methods to examine the adjusted relationship between perceived discrimination and receipt of preventive care. RESULTS: Discrimination was reported by 4.7% of respondents, and among these respondents the most commonly reported reasons were related to type of insurance (27.6%), race or ethnicity (13.7%), and income (6.7%). In adjusted analyses, persons who reported discrimination were less likely to receive 4 preventive services (cholesterol testing for cardiovascular disease, hemoglobin A1c testing and eye exams for diabetes, and flu shots), but not 2 other services (aspirin for cardiovascular disease, prostate specific antigen testing). Adjusting for perceived discrimination did not significantly change the relative likelihood of receipt of preventive care by race/ethnieity, gender, and insurance status. CONCLUSIONS: Persons who report discrimination may be less likely to receive some preventive health services. However, perceived discrimination is unlikely to account for a large portion of observed disparities in receipt of preventive care.

Increased Ambulatory Care Copayments and Hospitalizations among the Elderly

BACKGROUND When copayments for ambulatory care are increased, elderly patients may forgo important outpatient care, leading to increased use of hospital care. METHODS We compared longitudinal changes in the use of outpatient and inpatient care between enrollees in Medicare plans that increased copayments for ambulatory care and enrollees in matched control plans--similar plans that made no changes in these copayments. The study population included 899,060 beneficiaries enrolled in 36 Medicare plans during the period from 2001 through 2006. RESULTS In plans that increased copayments for ambulatory care, mean copayments nearly doubled for both primary care (

11.38, respectively. In the year after the rise in copayments, plans that increased cost sharing had 19.8 fewer annual outpatient visits per 100 enrollees (95% confidence interval [CI], 16.6 to 23.1), 2.2 additional annual hospital admissions per 100 enrollees (95% CI, 1.8 to 2.6), 13.4 more annual inpatient days per 100 enrollees (95% CI, 10.2 to 16.6), and an increase of 0.7 percentage points in the proportion of enrollees who were hospitalized (95% CI, 0.51 to 0.95), as compared with concurrent trends in control plans. These estimates were consistent among a cohort of continuously enrolled beneficiaries. The effects of increases in copayments for ambulatory care were magnified among enrollees living in areas of lower income and education and among enrollees who had hypertension, diabetes, or a history of myocardial infarction. CONCLUSIONS Raising cost sharing for ambulatory care among elderly patients may have adverse health consequences and may increase total spending on health care.

Insurance Parity and the Use of Outpatient Mental Health Care Following a Psychiatric Hospitalization

CONTEXT In 2005, the Healthcare Effectiveness Data and Information Set (HEDIS) introduced a quality measure to assess the receipt of disease-modifying antirheumatic drugs (DMARDs) among patients with rheumatoid arthritis (RA). OBJECTIVE To identify sociodemographic, community, and health plan factors associated with DMARD receipt among Medicare managed care enrollees. DESIGN, SETTING, AND PARTICIPANTS We analyzed individual-level HEDIS data for 93,143 patients who were at least 65 years old with at least 2 diagnoses of RA within a measurement year (during 2005-2008). Logistic regression models with generalized estimating equations were used to determine factors associated with DMARD receipt and logistic regression was used to adjust health plan performance for case mix. MAIN OUTCOME MEASURES Receipt or nonreceipt of DMARD. RESULTS The mean age of patients was 74 years; 75% were women and 82% were white. Overall performance on the HEDIS measure for RA was 59% in 2005, increasing to 67% in 2008 (P for trend <.001). The largest difference in performance was based on age: patients aged 85 years and older had a 30 percentage point lower rate of DMARD receipt (95% confidence interval [CI], -29 to -32 points; P < .001), compared with patients 65 to 69 years of age, even after adjusting for other factors. Lower percentage point rates were also found for patients who were men (-3 points; 95% CI, -5 to -2 points; P < .001), of black race (-4 points; 95% CI, -6 to -2 points; P < .001), with low personal income (-6 points; 95% CI, -8 to -5 points; P < .001), with the lowest zip code-based socioeconomic status (-4 points; 95% CI, -6 to 2 points; P < .001), or enrolled in for-profit health plans (-4 points; 95% CI, -7 to 0 points; P < .001); and in the Middle Atlantic region (-7 points; 95% CI, -13 to -2 points; P < .001) and South Atlantic regions (-11 points; 95% CI, -20 to -3 points; P < .001) as compared with the Pacific region. Performance varied widely by health plan, ranging from 16% to 87%. CONCLUSIONS Among Medicare managed care enrollees carrying a diagnosis of RA between 2005 and 2008, 63% received a DMARD. Receipt of DMARDs varied based on demographic factors, socioeconomic status, geographic location, and health plan.

Factors Influencing the Effectiveness of Interventions to Reduce Racial and Ethnic Disparities in Health care

Both government and private health care systems have engaged in efforts to improve quality, but the effect of these initiatives on racial and ethnic disparities has not been well studied. In the decade following an organizational transformation, the Veterans Affairs (VA) health care system achieved substantial improvements in quality of care with minimal racial disparities for most process-of-care measures, such as rates of cholesterol screenings. However, in our study we observed a striking disconnect between high levels of performance on widely used process measures and modest levels of improvement in clinical outcomes, such as control of blood pressure, blood glucose, and cholesterol levels. We also observed a gap in clinical outcomes of as much as nine percentage points between African American veterans and white veterans. Almost all of the disparity in outcomes in the VA was explained by within-facility disparity, which suggests that VA medical centers need to measure and address racial gaps in care for their patient populations. Moreover, because cardiovascular disease and diabetes are major contributors to racial disparities in life expectancy, the findings of this study and others underscore the urgency of focused efforts to improve intermediate outcomes among African Americans in the VA and other settings.
