Gender and ethnic/racial disparities in health care utilization among older adults

OBJECTIVE: We examine the role of economic access in gender and ethnic/racial disparities in the use of health services among older adults. METHODS: Data from the 1993-1995 study on the Asset of Health Dynamics Among the Oldest Old (AHEAD) were used to investigate differences in the 2-year use of health services by gender and among non-Hispanic White versus minority (Hispanic and African American) ethnic/racial groups. Analyses account for predisposing factors, health needs, and economic access. RESULTS: African American men had fewer physician contacts; minority and non-Hispanic White women used fewer hospital or outpatient surgery services; minority men used less outpatient surgery; and Hispanic women were less likely to use nursing home care, compared with non-Hispanic White men, controlling for predisposing factors and measures of need. Although economic access was related to some medical utilization, it had little effect on gender/ethnic disparities for services covered by Medicare. However, economic access accounted for minority disparities in dental care, which is not covered by Medicare. DISCUSSION: Medicare plays a significant role in providing older women and minorities access to medical services. Significant gender and ethnic/racial disparities in use of medical services covered by Medicare were not accounted for by economic access among older adults with similar levels of health needs. Other cultural and attitudinal factors merit investigation to explain these gender/ethnic disparities.     

Ethnicity and psychiatric comorbidity among alcohol-dependent persons who receive inpatient treatment: African Americans,Alaska natives,Caucasians, and Hispanics

This study examined ethnic and gender differences of psychiatric comorbidity among alcohol dependent men and women from four ethnic groups: Alaska Native, Caucasians, African Americans, and Hispanics. The data were obtained through individual standardized interview; DSM-III-R diagnoses were obtained via a computer algorithm. The subjects included 1177 Caucasians, 361 African Americans, 93 Hispanics and 486 Alaska Natives. Significant ethnic differences were found in relation to age of onset of alcohol and multiple substance dependence and psychiatric comorbidity. Ethnic differences were also noted with regard to the health care utilization.     

Trends and Outcomes in the Hospitalization of Older Americans for Cardiac Conduction Disorders or Arrhythmias, 1991–1998

OBJECTIVE: To identify epidemiological trends and measure outcomes in elderly patients hospitalized for cardiac conduction disorders or arrhythmias. DESIGN: Review of the standard 5% samples of the Medicare Provider Analysis and Review Files to characterize 144,512 discharges from 1991 through 1998 in which the principal diagnosis was a conduction disorder or arrhythmia, using the corresponding Enrollment Databases for denominator data. SETTING: Short-stay hospitals in the United States. PARTICIPANTS: Medicare beneficiaries age 65 and older in the standard 5% sample. MEASUREMENTS: Diagnosis-specific trends and rates; discharges by year; cumulative age-, race-, and sex-specific discharge rates; mean length of stay in hospital and in intensive care; mean Medicare reimbursement to the hospital; case-fatality rate in hospital; discharge destinations of patients discharged alive. RESULTS: Annual hospitalizations for sinoatrial node dysfunction, atrial flutter, atrial fibrillation, or ventricular fibrillation increased more rapidly than did the elderly Medicare beneficiary population. Hospitalizations with a principal diagnosis of ventricular extrasystoles or asystole showed steep secular declines. Discharge rates for sinoatrial node dysfunction, a group of rhythms with a nonsinus pacemaker, atrial fibrillation, Mobitz I, or complete atrioventricular block all increased steeply and continuously with patient age. In contrast, discharge rates for atrial flutter or ventricular tachycardia or fibrillation peaked among 75- to 84-year-old patients. White men were at uniquely high risk of hospitalization for atrial flutter or ventricular tachycardia or fibrillation, and, among the white majority, men had higher discharge rates than women for nine of the 11 commonest rubrics. Whites, particularly white women, had the highest discharge rates for atrial fibrillation. Blacks, especially black women, were at disproportionate risk for hospitalization for the group of nonsinus pacemaker rhythms. Diagnosis-specific mean resource costs were strongly correlated with each other and with mean Medicare reimbursement but not with case-fatality rate. CONCLUSION: Medicare claims data demonstrated striking differences among and within diagnoses of heart blocks or arrhythmias in terms of the populations at greatest risk for hospitalization. This variation should be explored further to generate and test hypotheses about differential causation or delivery of care.     

Comparison of data quality for reports and ratings of ambulatory care by African American and White Medicare managed care enrollees

OBJECTIVE: Compare missing data and reliability of health care evaluations between African Americans and Whites in Medicare managed care health plans. METHOD: Consumer Assessment of Healthcare Providers and Systems (CAHPS) 3.0 health plan survey data collected from 109,980 Medicare managed care enrollees (101,189 Whites, 8,791 African Americans) in 321 plans. Participants self-administered the survey and four single-item global ratings of care. RESULTS: Missing data rates were significantly higher for African Americans than Whites on all CAHPS items (p < .0001). Internal consistency reliability estimates for the CAHPS scales did not differ significantly between African Americans and Whites, but plan-level reliability estimates for the scales and global rating items were significantly lower for African Americans than Whites. DISCUSSION: Higher missing data rates and lower plan-level reliability estimates for African American Medicare managed care enrollees suggest caution in making race/ethnicity comparisons. Future efforts are needed to enhance the quality of data collected from older African Americans.     

Prevalence and correlates of metabolic syndrome based on a harmonious definition among adults in the US

Background: Recently, a Joint Scientific Statement bridged differences between previous definitions of metabolic syndrome. Our objective was to estimate the prevalence of metabolic syndrome in a representative sample of US adults and to examine its correlates. Methods: We analyzed data for up to 3461 participants aged ≥20 years of the 2003–2006 National Health and Nutrition Examination Survey. Results: Using waist circumference thresholds of ≥102 cm for men and ≥88 cm for women, the age‐adjusted prevalence of metabolic syndrome was 34.3% among all adults, 36.1% among men, and 32.4% among women. Using racial‐ or ethnic‐specific International Diabetes Federation criteria for waist circumference, the age‐adjusted prevalence of metabolic syndrome was 38.5% for all participants, 41.9% for men, and 35.0% for women. Prevalence increased with age, peaking among those aged 60–69 years. Prevalence was lower among African American men than White or Mexican American men, and lower among White women than among African American or Mexican American women. In a multivariate regression model, significant independent associations were noted for age (positive), gender (men higher than women), race or ethnicity (African Americans and participants of another race lower than Whites), educational status (inverse), hypercholesterolemia (positive), concentrations of C‐reactive protein (positive), leisure time physical activity (inverse), microalbuminuria (positive), and hyperinsulinemia (positive). Additional adjustment for body mass index weakened many of the associations, with educational status and microalbuminuria no longer significant contributors to the model. Conclusion: Metabolic syndrome continues to be highly prevalent among adults in the US.     

Are there Gender Differences in Diabetes Care Among Elderly Medicare Enrolled Veterans?

OBJECTIVE: To examine gender differences in diabetes care process measures and intermediate outcomes among veteran clinic users.
DESIGN: A retrospective cohort study using Veterans Health Administration (VHA) and Medicare files of VHA clinic users with diabetes. Diabetes care process measures were tests for hemoglobin A1c (HbA1c), low-density lipoprotein (LDL-C) values, and eye exams. Intermediate outcomes were HbA1c and LDL-C values below recommended thresholds. Chi-square tests and logistic regressions were used to assess gender differences.
PARTICIPANTS: Study population included 3,225 women and 231,922 men veterans with diabetes, enrolled in Medicare fee-for-service and alive at the end of fiscal year 2000.
RESULTS: Overall, there were no significant gender differences in HbA1c or LDL-C testing. However, women had higher rates in these process measures than men among the non-African American minorities. Women were more likely to have completed eye exams (odds ratio [OR]=1.11; 99% confidence interval [CI]=1.10, 1.23) but were less likely to have LDL-C under 130 mg/dL (OR=0.77; 99% CI=0.69, 0.87).
CONCLUSIONS: Among VHA patients with diabetes, clinically significant gender inequality was not apparent in most of diabetes care measures. However, there was evidence of better care among nonwhite and non-African American women than their male counterparts. Further research on interaction of race and gender on diabetes care is needed. This includes evaluation of integrated VHA women's health programs as well as cultural issues. Lower LDL-C control among women suggests areas of unmet needs for women and opportunities for future targeted quality improvement interventions at system and provider levels.     

Effect of race on cultural justifications for caregiving

OBJECTIVE: Our objective in this study was to explore the effects of caregiver characteristics on cultural reasons given for providing care to dependent elderly family members. METHODS: The sample included 48 African American and 121 White caregivers. Using multivariate analyses, we used caregiver characteristics (e.g., race, gender, education) to predict scores on the Cultural Justifications for Caregiving Scale (CJCS). RESULTS: Confirmatory factor analysis showed that the CJCS was appropriate for both African American and White caregivers. African Americans had stronger cultural reasons for providing care than Whites, education levels were inversely related to CJCS scores, and the influences of gender and age on cultural reasons were moderated by race. Compared to females, African American males had lower CJCS scores, whereas White males had higher CJCS scores. Younger as compared to older White caregivers had higher CJCS scores. DISCUSSION: This study supports the long-standing cultural tradition of African American families providing care to dependent elders. Cultural reasons for caregiving need to be interpreted within the context of race and gender socialization. Social roles, such as husband or wife, son or daughter, can also help determine how individuals within a particular cultural group experience cultural expectations and obligations. Information from this study can inform culturally appropriate caregiving interventions.     

Binge drinking by gender and race/ethnicity among California adults, 2007/2009

Background: This study provides binge drinking population estimates for California adults by gender and detailed race/ethnicity categories. This information may be helpful for planning targeted initiatives to decrease binge drinking. Method: Data were from the 2007 and 2009 California Health Interview Surveys. The 98?662 respondents represent an annual estimated population of 27.2 million adults. Survey adjusted binary logistic regression was used to calculate gender-specific binge drinking population rates and multinomial logit regression to estimate binge drinking frequency. Results: Adjusting for socio-demographics, any binge drinking during the past year was reported by 31.0% (95% Confidence Interval?=?30.5–31.4%) of men and 18.0% (17.7–18.3%) of women. Rates among White men and women were 30.5% and 19.6%, respectively. Binge drinking rates ranged from 11.9% among Chinese to 42.9% among Mexican men and from 4.8% among Vietnamese to 25.7% among “Other Latino” women. Five race/ethnicity categories of men and seven categories of women were significantly less likely to binge drink compared to Whites. Although Whites had the highest overall binge drinking rates, an estimated 12.5% of White men binge drank less than monthly, significantly exceeded by Mexican and Central American men, 19.9 and 19.6%, respectively. An estimated 9.6% of White women binge drank less than monthly, exceeded only by “Other Latino” women, 13.6%. Conclusion: These findings underscore the importance of detailed gender and race/ethnicity breakdowns when examining any binge drinking. Furthermore, there is variability across Asian and Latino subgroups in the frequency of binge drinking episodes, which is not evident in broad-group population studies.     

Lack of gender and racial differences in surgery and mortality in hospitalized medicare beneficiaries with bleeding peptic ulcer

Objective  Determine the relation of race and gender to outcome from bleeding peptic ulcer. Design  Retrospective cohort study. Setting  All acute care hospitals in the United States. Patients  A 100% sample of hospitalized Medicare beneficiaries older than 64 years (n=82,868) with a primary discharge diagnosis of peptic ulcer with hemorrhage. Measurements and main results  Surgical treatment was performed in 6.9% of patients, 30-day mortality was 8.5%, and average length of stay was 9.4 days. Surgery was somewhat more common in men than women (7.3% vs 6.5%,p<.001), and in whites than African Americans (6.9% vs 6.3%,p<.001), but neither race nor gender was associated with surgery in multivariable analysis adjusting for potentially confounding factors. Mortality rates were similar in African Americans and whites (8.5%), and somewhat higher in men than women (10.7% vs 9.3%,p<.001). In multivariable analysis, there was no difference in mortality across gender and racial groups. Although unadjusted and adjusted lengths of stay were longer for African Americans and shorter for men, the differences were modest (i.e., 16% increase and 6% decrease in multivariable analysis, respectively,p<.0001). Conclusions  In this national sample, there is no significant gender or racial difference in therapy and outcome for patients with hemorrhagic peptic ulcer. The findings raise the possibility that studies that have shown race and gender differences in management of coronary artery disease and cancer may not be generalizable to other common diagnoses.

Disparities in 30-day readmission rates among Medicare enrollees with dementia

Background

Readmissions contribute to excessive care costs and burden for people living with dementia. Assessments of racial disparities in readmissions among dementia populations are lacking, and the role of social and geographic risk factors such as individual-level exposure to greater neighborhood disadvantage is poorly understood. We examined the association between race and 30-day readmissions in a nationally representative sample of Black and non-Hispanic White individuals with dementia diagnoses.

Methods

This retrospective cohort study used 100% Medicare fee-for-service claims from all 2014 hospitalizations nationwide among Medicare enrollees with dementia diagnosis linked to patient, stay, and hospital factors. The sample consisted of 1,523,142 hospital stays among 945,481 beneficiaries. The relationship between all cause 30-day readmissions and the explanatory variable of self-reported race (Black, non-Hispanic White) was examined via generalized estimating equations approach adjusting for patient, stay, and hospital-level characteristics to model 30-day readmission odds.

Results

Black Medicare beneficiaries had 37% higher readmission odds compared to White beneficiaries (unadjusted OR 1.37, CI 1.35–1.39). This heightened readmission risk persisted after adjusting for geographic factors (OR 1.33, CI 1.31–1.34), social factors (OR 1.25, CI 1.23–1.27), hospital characteristics (OR 1.24, CI 1.23–1.26), stay-level factors (OR 1.22, CI 1.21–1.24), demographics (OR 1.21, CI 1.19–1.23), and comorbidities (OR 1.16, CI 1.14–1.17), suggesting racially-patterned disparities in care account for a portion of observed differences. Associations varied by individual-level exposure to neighborhood disadvantage such that the protective effect of living in a less disadvantaged neighborhood was associated with reduced readmissions for White but not Black beneficiaries. Conversely, among White beneficiaries, exposure to the most disadvantaged neighborhoods associated with greater readmission rates compared to White beneficiaries residing in less disadvantaged contexts.

Conclusions

There are significant racial and geographic disparities in 30-day readmission rates among Medicare beneficiaries with dementia diagnoses. Findings suggest distinct mechanisms underlying observed disparities differentially influence various subpopulations.     

Health and support service utilization patterns of American Indians and Alaska Natives diagnosed with HIV/AIDS.

The purpose of this analysis is twofold: to examine the types of health and support services provided by CARE Act funded providers to American Indians/Alaska Natives and to compare the characteristics and service utilization patterns for this group with those of individuals from other racial/ethnic groups. We present an analysis of the demographic characteristics, service utilization, and health outcomes of all HIV-infected clients who received services in five geographic areas at agencies that were funded through the Ryan White Comprehensive AIDS Resources Emergency (CARE) Act. Standard chi-square tests were used to test for statistically significant differences (p <.05) between the demographic characteristics and service utilization patterns of matched pairs of HIV-positive American Indian/Native Alaskans with HIV-positive individuals of other racial and ethnic backgrounds. Individuals were matched on gender, age, insurance, AIDS diagnosis, and site. Other data examined include client characteristics (income, homelessness, HIV exposure category, and source of health care), health indicators (CDC-defined disease stage, CD4+ counts, substance abuse and psychiatric illness) and service utilization (medical care; mental health treatment/counseling; substance abuse treatment/counseling; case management; dental care; housing, food, emergency financial, and transportation assistance, and buddy/companion and client advocacy services). There were no statistically significant differences between the two groups for HIV exposure category, CD4 count, substance abuse problem, and being homeless and in their likelihood to receive medical care, mental health or substance abuse treatment/counseling, dental care, food, emergency financial, and transportation assistance, as well as buddy/companion and client advocacy services. They were more likely (55% vs. 46%) to receive case management services than the matched individuals from other racial/ethnic groups. They were also more likely to receive housing assistance (35% vs. 25%). The analysis provides evidence that when individuals are matched on key demographic and health characteristics, few differences remain between HIV-positive American Indians/Native Alaskans and other racial/ethnic groups. The two exceptions are case management and housing assistance. The significantly higher use of case management is not surprising, given the emphasis by American Indians/Alaska Natives on traditional Native American case management case management. In contrast, the significantly higher use of housing assistance by American Indians/Alaska Natives was unexpected. Exploring the potential need for housing assistance among all American Indians/Alaska Natives served by the Ryan White CARE Act needs to be considered.     

Systemic sclerosis mortality in the United States: 1999-2002 implications for patient care.

OBJECTIVE: To describe the systemic sclerosis mortality rates in the United States between 1999 and 2002, a time period in which a new coding system was used to record deaths, and to describe its implications in patient care. METHODS: We used the mortality database from the National Center of Health Statistics and with the use of ICD-10 codes for systemic sclerosis calculated death rates by gender, race, age, state, and region for the United States. Death rates are expressed as per million population. RESULTS: Age-adjusted death rates for systemic sclerosis were 6.8 cases per million in women, 2.1 cases per million in men, and 4.7 cases per million for the whole population. Death rates peaked a decade earlier in the African American population when compared with those in the white population (65-74 vs. 75-84 years of age). Age-adjusted mortality was highest in African American women at 9.5 cases per million. CONCLUSION: Mortality rates for systemic sclerosis are slightly higher since the implementation of the new disease-specific ICD-10 coding system for recording deaths. Death rates related to systemic sclerosis among the African American population are remarkably higher than those among the white population; this is believed to be related to the more aggressive disease seen in the African American patients and to the disparity of healthcare resources. These findings suggest that earlier and more aggressive treatment is warranted in the African American population, with more frequent follow-up and preventive care.     

Are there gender differences in diabetes care among elderly medicare enrolled veterans?

OBJECTIVE: To examine gender differences in diabetes care process measures and intermediate outcomes among veteran clinic users. DESIGN: A retrospective cohort study using Veterans Health Administration (VHA) and Medicare files of VHA clinic users with diabetes. Diabetes care process measures were tests for hemoglobin A1c (HbA1c), low-density lipoprotein (LDL-C) values, and eye exams. Intermediate outcomes were HbA1c and LDL-C values below recommended thresholds. Chi-square tests and logistic regressions were used to assess gender differences. PARTICIPANTS: Study population included 3,225 women and 231,922 men veterans with diabetes, enrolled in Medicare fee-for-service and alive at the end of fiscal year 2000. RESULTS: Overall, there were no significant gender differences in HbA1c or LDL-C testing. However, women had higher rates in these process measures than men among the non-African American minorities. Women were more likely to have completed eye exams (odds ratio [OR]=1.11; 99% confidence interval [CI]=1.10, 1.23) but were less likely to have LDL-C under 130 mg/dL (OR=0.77; 99% CI=0.69, 0.87). CONCLUSIONS: Among VHA patients with diabetes, clinically significant gender inequality was not apparent in most of diabetes care measures. However, there was evidence of better care among nonwhite and non-African American women than their male counterparts. Further research on interaction of race and gender on diabetes care is needed. This includes evaluation of integrated VHA women’s health programs as well as cultural issues. Lower LDL-C control among women suggests areas of unmet needs for women and opportunities for future targeted quality improvement interventions at system and provider levels.     

Relative body weight and psychological distress in late life: observations of gender and race comparisons

OBJECTIVE: This study examines the association between relative body weight (measured with body mass index; BMI) and multiple forms of psychological distress and whether those associations are contingent on gender and race. METHOD: Interviews were conducted in 2001-2002 with persons 65 years and older in the District of Columbia and adjoining Maryland counties (N = 1,152). BMI is associated (a) positively with depression, anger, and physical symptoms among White women; (b) positively with physical symptoms among Black women and men; and (c) negatively with anxiety among White men. RESULTS: Tests for gender by race interactions find significant contrasts between White women and men when depression, anxiety, and physical symptoms are considered as outcomes; contrasts between White and Black women are significant for anger. DISCUSSION: Results underscore the importance of gender by race interactions, multiple forms of distress in analyses of effects of BMI, and the role of negative self-evaluations and health difficulties as explanations.     

A Pilot Trial Examining African American and White Responses to Algorithm-Guided Smoking Cessation Medication Selection in Persons Living with HIV

Algorithm-based treatments (AT) may be an effective clinical tool to aid HIV clinicians in prescribing pharmacotherapy to increase smoking cessation among people living with HIV (PLWH). Initial results from AT indicated significant increases in abstinence self-efficacy and medication utilization and declines in cigarettes smoked per day across time. Given historical racial disparities, it is unclear if both African Americans and White smokers would benefit equally from this type of intervention. Thus, the aim of this study was to examine racial differences in response to AT guided smoking cessation for African American and White smokers living with HIV. One hundred PLWH smokers (n = 100) were randomized to receive either AT guided smoking cessation or Treatment as Usual (TAU) which consisted of instructing participants to talk to a provider about smoking cessation assistance when ready to make a quit attempt. Participants were African American (75%) and White (25%) and majority men (71%) who had never been married (56%). African Americans smoked fewer cigarettes and were more likely to smoke mentholated cigarettes compared to White smokers at baseline. African Americans increased their use of other tobacco products (cigars/cigarillos) over time relative to White smokers. A significant interaction between race and quit goal was observed, with White smokers who reported complete abstinence as their goal having higher quit rates, while African Americans who reported a goal other than complete abstinence demonstrating higher quit rates. The increased use of cigars/cigarillos during quit attempts as well as having a goal other than complete abstinence should be considered when applying algorithm based interventions for PLWH African American smokers.     

Racial and ethnic disparities in the treatment of dementia among Medicare beneficiaries

OBJECTIVES: Numerous studies have documented disparities in health care utilization between non-Hispanic White and minority elders. We investigated differences in anti-dementia medication use between non-Hispanic White and minority community-dwelling Medicare beneficiaries with dementia. METHODS: Using multivariate analysis with generalized estimating equations, we estimated prevalence ratios (PRs) for anti-dementia medication use by race/ethnicity for 1,120 beneficiaries with dementia from years 2001 through 2003 of the Medicare Current Beneficiary Survey. RESULTS: After adjusting for demographics, socioeconomics, health care access and utilization, comorbidities, and service year, we found that anti-dementia medication use was approximately 30% higher among non-Hispanic Whites compared to other racial/ethnic groups (PR=0.73, 95% confidence interval [CI]=0.59, 0.91). As for individual racial/ethnic groups, prevalence disparities remained significant for non-Hispanic Blacks (PR=0.75, 95% CI=0.57, 0.99) and non-Hispanic others (PR=0.50, 95% CI=0.26, 0.96) but were attenuated for Hispanics (PR=0.84, 95% CI=0.59, 1.20). DISCUSSION: Results provide evidence that racial/ethnic disparities in utilization of drugs used to treat dementia exist and are not accounted for by differences in demographic, economic, health status, or health utilization factors. Findings provide a foundation for further research that should use larger numbers of minority patients and consider dementia type and severity, access to specialty dementia care, and cultural factors.     

Racial differences in the cost of treating men with early-stage prostate cancer

OBJECTIVE: To compare the cost and resource utilization in the evaluation, treatment, and 6-month follow-up of African-American and White men undergoing either external beam radiation therapy (XRT) or radical prostatectomy (RP) for early-stage prostate cancer. DESIGN: Retrospective analysis of cost and resource utilization data from encrypted patient-specific hospital inpatient, hospital outpatient, and physician/supplier data files. SETTING: National Medicare claims data from 1993 through 1996. PARTICIPANTS: A random 5% national sample of Medicare beneficiaries from the Health Care Financing Administration Public Use Files for 1993 through 1996. MEASUREMENTS: Inpatient, outpatient, and physician/supplier Medicare costs. RESULTS: African-American men undergoing RP for early-stage prostate cancer had significantly higher costs ($21,878 vs $18,786, P < .0001) than did White men. Most of the difference occurred in the inpatient setting. African-American men undergoing XRT had significantly greater costs ($18,131 vs $15,734, P < .0001) than did White men. Most of this difference was generated by longer duration of XRT treatments. CONCLUSIONS: In early-stage prostate cancer, charges for RP and XRT in African-American men are higher when compared with those for White men.
