Affordable Care Act and Disparities in Health Services Utilization among Ethnic Minority Breast Cancer Survivors: Evidence from Longitudinal Medical Expenditure Panel Surveys 2008⁻2015.

Breast cancer is the most prevalent female cancer in the US. Incidence rates are similar for white and black women but mortality rates are higher for black women. This study draws on rich, nationally representative data, the 2008⁻2015 Medical Expenditure Panel Surveys, to estimate effects of the Affordable Care Act (ACA) on reducing disparities in and access to use of diagnostic and medical services for black and Hispanic breast cancer survivors. Random effects multinomial logit, flexible hurdle and Box-Cox estimation techniques are used. The robust estimates indicate that the ACA narrowed the racial/ethnic disparity in health insurance coverage, health care utilization and out-of-pocket prescription drug expenditures among breast cancer survivors. Gaps in uninsurance significantly declined for black and Hispanic survivors. Hispanic women generally and black breast cancer survivors specifically increased use of mammography services post-ACA. The ACA did not significantly impact disparities in physician utilization or out-of-pocket prescription drug expenditures for Hispanic survivors, while there were substantive improvements for black breast cancer survivors. The paper concludes with a discussion of the strengths and limitations of the ACA for reducing disparities and improving health outcomes for a growing population of breast cancer survivors in the US.

Racial and Ethnic Disparities in Patient-Provider Communication With Breast Cancer Patients: Evidence From 2011 MEPS and Experiences With Cancer Supplement.

The current study explores racial/ethnic disparities in the quality of patient-provider communication during treatment, among breast cancer patients. A unique data set, Medical Expenditure Panel Survey and Experiences With Cancer Supplement 2011, is used to examine this topic. Using measures of the quality of patient-provider communication that patients are best qualified to evaluate, we explore the relationship between race/ethnicity and patients' perspectives on whether (1) patient-provider interactions are respectful, (2) providers are listening to patients, (3) providers provide adequate explanations of outcomes and treatment, and (4) providers spend adequate time in interacting with the patients. We also examine the relationship between race/ethnicity and patients' perspectives on whether their (1) doctor ever discussed need for regular follow-up care and monitoring after completing treatment, (2) doctor ever discussed long-term side effects of cancer treatment, (3) doctor ever discussed emotional or social needs related to cancer, and (4) doctor ever discussed lifestyle or health recommendations. Multivariate ordinary least squares and ordered logistic regression models indicate that after controlling for factors such as income and health insurance coverage, the quality of patient-provider communication with breast cancer patients varies by race/ethnicity. Non-Hispanic blacks experience the greatest communication deficit. Our findings can inform the content of future strategies to reduce disparities.

Potential Health Implications of Medication Therapy Management Eligibility Criteria in the Patient Protection and Affordable Care Act Across Racial and Ethnic Groups.

BACKGROUND: The Medicare Prescription Drug, Improvement, and Modernization Act requires Part D plans to establish programs to provide medication therapy management (MTM) services starting from 2006. MTM services have been found to improve patient outcomes from pharmacotherapy, reduce emergency room visits and hospitalizations, and reduce health care costs in a cost-effective fashion. However, previous research found that non-Hispanic blacks (blacks) and Hispanics may be less likely to be eligible for MTM services than non-Hispanic whites (whites) among the Medicare population, according to current Medicare MTM eligibility criteria. This finding is because Medicare MTM eligibility criteria are predominantly based on medication use and costs, and blacks and Hispanics tend to use fewer prescription medications and incur lower prescription medication costs. The Patient Protection and Affordable Care Act (PPACA) laid out a set of MTM eligibility criteria for eligible entities to target patients for MTM services: "(1) take 4 or more prescribed medications ...; (2) take any 'high risk' medications; (3) have 2 or more chronic diseases ... or (4) have undergone a transition of care, or other factors ... that are likely to create a high risk of medication-related problems." OBJECTIVES: To (a) examine racial/ethnic disparities in meeting the eligibility criteria for MTM services in PPACA among the Medicare population and (b) determine whether there would be greater disparities in health and economic outcomes among MTM-ineligible than MTM-eligible groups. METHODS: This was a retrospective cross-sectional analysis of the Medicare Current Beneficiaries Survey (2007-2008). To determine medication characteristics, the U.S. Food and Drug Administration's Electronic Orange Book was also used. Proportions of the population eligible for MTM services based on PPACA MTM eligibility criteria were compared across racial and ethnic groups using a chi-square test; a logistic regression model was used to adjust for population sociodemographic and health characteristics. Health and economic outcomes examined included health status (self-perceived good health status, number of chronic diseases, activities of daily living [ADLs], and instrumental activities of daily living [IADLs]), health services utilization and costs (physician visits, emergency room visits, and total health care costs), and medication use patterns (generic dispensing ratio). To determine difference in disparities across MTM eligibility categories, difference-in-differences regressions of various functional forms were employed, depending on the nature of the dependent variables. Interaction terms between the dummy variables for minority groups (e.g., blacks or Hispanics) and MTM eligibility were included to test whether disparity patterns varied between MTM-ineligible and MTM-eligible individuals. RESULTS: The sample consisted of 12,966 Medicare beneficiaries, of which 11,161 were white, 930 were black, and 875 were Hispanic. Of the study sample, 9,992 whites (86.4%), 825 blacks (86.3%), and 733 Hispanics (80.6%) were eligible for MTM. The difference between whites and Hispanics was significant (P less than 0.050), and the difference between whites and blacks was not significant (P greater than 0.050). In multivariate analyses, significant disparity in eligibility for MTM services was found only between Hispanics and whites (odds ratio [OR] = 0.59; 95% CI = 0.43-0.82) but not between blacks and whites (OR = 0.78; 95% CI = 0.55-1.09). Disparities were greater among the MTM-ineligible than the MTM-eligible populations in self-perceived health status, ADLs, and IADLs for both blacks and Hispanics compared with whites. When analyzing the number of chronic conditions, the number and costs of physician visits, and total health care costs, the authors of this study found lower racial and ethnic disparities among the ineligible population than the eligible population. CONCLUSIONS: Hispanics are significantly less likely than whites to qualify for MTM among the Medicare population, according to MTM eligibility criteria stipulated in the PPACA. PPACA MTM eligibility criteria may aggravate existing racial and ethnic disparities in health status but may remediate racial and ethnic disparities in health services utilization. Alternative MTM eligibility criteria other than PPACA MTM eligibility criteria may be needed to improve the efficiency and equity of access to Medicare Part D MTM programs.

Potential effects of racial and ethnic disparities in meeting Medicare medication therapy management eligibility criteria.

OBJECTIVE: Medication therapy management (MTM) has the potential to play an instrumental role in reducing racial and ethnic disparities in health care. However, previous research has found that Blacks and Hispanics are less likely to be eligible for MTM. The purpose of the current study was to examine the potential effects of MTM eligibility criteria on racial and ethnic disparities in health outcomes. METHODS: The current study is a retrospective cross-sectional analysis of the Medicare Current Beneficiary Survey Cost and Use files for the years 2007 and 2008. A difference-in-differences model was used to compare disparities in outcomes between ineligible and eligible beneficiaries according to MTM eligibility criteria in 2010. This was achieved by including in regression models interaction terms between dummy variables for Blacks/Hispanics and MTM eligibility criteria. Interaction terms were interpreted on both multiplicative and additive terms. Various regression models were used depending on the types of variables. KEY FINDINGS: Whites were more likely to report self-perceived good health status than Blacks and Hispanics among both MTM-eligible and MTM-ineligible populations. Disparities were greater among MTM-ineligible than MTM-eligible populations (e.g., on additive term, difference in odds=1.94 and P<0.01 for Whites and Blacks; difference in odds=2.86 and P<0.01 for Whites and Hispanics). A few other measures also exhibited significant patterns. CONCLUSIONS: MTM eligibility criteria may exacerbate racial and ethnic disparities in health status and some measures of health services utilizations and costs and medication utilization. Future research should examine strategies to remediate the effects of MTM eligibility criteria on disparities.

Potential health implications of racial and ethnic disparities in meeting MTM eligibility criteria.

BACKGROUND: Previous studies have found that racial and ethnic minorities would be less likely to meet the Medicare eligibility criteria for medication therapy management (MTM) services than their non-Hispanic White counterparts. OBJECTIVES: To examine whether racial and ethnic disparities in health status, health services utilization and costs, and medication utilization patterns among MTM-ineligible individuals differed from MTM-eligible individuals. METHODS: This study analyzed Medicare beneficiaries in 2004-2005 Medicare Current Beneficiary Survey. Various multivariate regressions were employed depending on the nature of dependent variables. Interaction terms between the dummy variables for Blacks (and Hispanics) and MTM eligibility were included to test whether disparity patterns varied between MTM-ineligible and MTM-eligible individuals. Main and sensitivity analyses were conducted for MTM eligibility thresholds for 2006 and 2010. RESULTS: Based on the main analysis for 2006 MTM eligibility criteria, the proportions for self-reported good health status for Whites and Blacks were 82.82% vs. 70.75%, respectively (difference = 12.07%; P < 0.001), among MTM-ineligible population; and 56.98% vs. 52.14%, respectively (difference = 4.84%; P = 0.31), among MTM-eligible population. The difference between these differences was 7.23% (P < 0.001). In the adjusted logistic regression, the interaction effect for Blacks and MTM eligibility had an OR of 1.57 (95% Confidence Interval, or CI = 0.98-2.52) on multiplicative term and difference in odds of 2.38 (95% CI = 1.54-3.22) on additive term. Analyses for disparities between Whites and Hispanics found similar disparity patterns. All analyses for 2006 and 2010 eligibility criteria generally reported similar patterns. Analyses of other measures did not find greater racial or ethnic disparities among the MTM-ineligible than MTM-eligible individuals. CONCLUSIONS: Disparities in MTM eligibility may aggravate existing racial and ethnic disparities in health outcomes. However, disparities in MTM eligibility may not aggravate existing disparities in health services utilization and costs and medication utilization patterns. Future studies should examine the effects of Medicare Part D on these disparities.

Effects of medicare part d on disparity implications of medication therapy management eligibility criteria.

BACKGROUND: Previous studies have shown that there were greater racial and ethnic disparities among individuals who were ineligible for medication therapy management (MTM) services than among MTM-eligible individuals before the implementation of Medicare Part D in 2006. OBJECTIVE: To determine whether the implementation of Medicare Part D in 2006 correlates to changes in racial and ethnic disparities among MTM-ineligible and MTM-eligible beneficiaries. METHODS: Data from the Medicare Current Beneficiary Survey were analyzed in this retrospective observational analysis. To examine potential racial and ethnic disparities, non-Hispanic whites were compared with non-Hispanic blacks and Hispanics. Three aspects of disparities were analyzed, including health status, health services utilization and costs, and medication utilization patterns. A generalized difference-in-differences analysis was used to examine the changes in difference in disparities between MTM-ineligible and MTM-eligible individuals from 2004-2005 to 2007-2008 relative to changes from 2001-2002 and 2004-2005. Various multivariate regressions were used based on the types of dependent variables. A main analysis and several sensitivity analyses were conducted to represent the ranges of MTM eligibility thresholds used by Medicare Part D plans in 2010. RESULTS: The main analysis showed that Part D implementation was not associated with reductions in greater racial and ethnic disparities among MTM-ineligible than MTM-eligible Medicare beneficiaries. The main analysis suggests that after Part D implementation, Medicare MTM eligibility criteria may not consistently improve the existing racial and ethnic disparities in health status, health services utilization and costs, and medication utilization. By contrast, several sensitivity analyses showed that Part D implementation did correlate with a significant reduction in greater racial disparities among the MTM-ineligible group than the MTM-eligible group in activities of daily living and in instrumental activities of daily living. Part D implementation may be also associated with a reduction in greater ethnic disparities among the MTM-ineligible group than the MTM-eligible groups in the costs of physician visits. CONCLUSION: Part D implementation was not associated with consistent reductions in the disparity implications of the Medicare MTM eligibility criteria. The main analysis showed that Part D implementation was not associated with a reduction in disparities associated with MTM eligibility, although several sensitivity analyses did show reductions in disparities in specific aspects. Future research should explore alternative Medicare MTM eligibility criteria to eliminate racial and ethnic disparities among the Medicare population.

Accessibility of antiretroviral therapy in Ghana: convenience of access.

The convenience of accessing antiretroviral therapy (ART) is important for initial access to care and subsequent adherence to ART. We conducted a qualitative study of people living with HIV/AIDS (PLWHA) and ART healthcare providers in Ghana in 2005. The objective of this study was to explore the participants' perceived convenience of accessing ART by PLWHA in Ghana. The convenience of accessing ART was evaluated from the reported travel and waiting times to receive care, the availability, or otherwise, of special considerations, with respect to the waiting time to receive care, for those PLWHA who were in active employment in the formal sector, the frequency of clinic visits before and after initiating ART, and whether the PLWHA saw the same or different providers at each clinic visit (continuity of care). This qualitative study used in-depth interviews based on Yin's case-study research design to collect data from 20 PLWHA and 24 ART healthcare providers as study participants. • Reported travel time to receive ART services ranged from 2 to 12 h for 30% of the PLWHA. • Waiting time to receive care was from 4 to 9 h. • While known government workers, such as teachers, were attended to earlier in some of the centres, this was not a consistent practice in all the four ART centres studied. • The PLWHA corroborated the providers' description of the procedure for initiating and monitoring ART in Ghana. • PLWHA did not see the same provider every time, but they were assured that this did not compromise the continuity of their care. Our study suggests that convenience of accessing ART is important to both PLWHA and ART healthcare providers, but the participants alluded to other factors, including open provider-patient communication, which might explain the PLWHA's understanding of the constraints under which they were receiving care. The current nation-wide coverage of the ART programme in Ghana, however, calls for the replication of this study to identify possible perception changes over time that may need attention. Our study findings can inform interventions to promote access to ART, especially in Africa.

Cost burden of the presenteeism health outcome: diverse workforce of nurses and pharmacists.

OBJECTIVES: To describe presenteeism, its cost burden, and comparative and interactive effects of race/ethnicity in nurses and pharmacists. METHODS: Using 226 self-reports, ordinal logistic regression with marginal/interactive effects modeled 12 presenteeism predictors, contingency tables detected differences/associations, and Human Capital Approach determined cost burden. RESULTS: Presenteeism's prevalence was 52.65% with mean productivity decrement 13.2%. Minorities had lower base presenteeism rates; however, race/ethnicity differences were not significant. Physical symptoms and mental conditions were associated with increased presenteeism likelihood, while decreased likelihood was associated with no medications or lack of resumption of previous medications. Indirect cost burden in 2008 averaged $12,605 per professional for $36 billion nationally. CONCLUSIONS: Prevention of symptoms and conditions impacting cognitions, pain, and perceptions can decrease presenteeism. Minorities' lower rates of presenteeism can be viewed both positively and negatively.

Medical Expenditure Panel Survey: a valuable database for studying racial and ethnic disparities in prescription drug use.

BACKGROUND: Despite the importance of equal access to prescription drugs by racial and ethnic groups, studies on access to prescription drugs have been incomprehensive. OBJECTIVE: To describe the Medical Expenditure Panel Survey (MEPS) as a valuable data source to study racial and ethnic disparities in prescription drug use. METHODS: Use of the MEPS database to study disparities in prescription drug use is detailed. This includes strengths and limitations of the database, as well as key methodological, sampling, and statistical issues to consider when using it. RESULTS: Using MEPS allows researchers to control for sociodemographic and health status information when studying racial and ethnic disparities in prescription drug use. MEPS has taken measures to improve reliability of the information on the utilization of prescription drugs. An additional benefit of MEPS is that it has oversampled Hispanics, Blacks, and Asians; as such, it affords the statistical power to examine these minority groups. One limitation of MEPS is the inability of researchers to study some drug categories, because of limitations in statistical power. Moreover, the names of the prescription medications are not standardized in MEPS, and some information is not publicly available in MEPS databases. When conducting studies requiring information not publicly available, researchers may commute to the MEPS Data Center or may request the Data Center to run statistical programs for them. CONCLUSIONS: Using MEPS to study racial and ethnic disparities in prescription drug use has significant benefits. Nonetheless, researchers need to keep in mind the limitations of using MEPS.

Parent caregiving choices of middle-generation Blacks and Whites in the United States.

OBJECTIVE: This study compares how middle-generation caregivers and non-caregivers differ by race and explores racial differences in activities of daily living (ADL), instrumental activities of daily living (IADL), and financial assistance that middle-generation caregivers provide for their parents. METHOD: Using 2000 Health and Retirement Study data, racially stratified descriptive analyses and logistic regression models for ADL, IADL, and financial assistance are presented. RESULTS: Parental need and race influence support, with similar patterns of Black and White ADL support, but racial differences in IADL and financial support. Having more children motivates Whites to increase IADL support and reduce financial support; more children decreases Blacks' IADL support. Sibling caregiver networks influence IADL and financial support in ways that vary by race. The number employed is a key determinant for Blacks for all support, but only influences White ADL support. DISCUSSION: The findings of this article indicate the importance of sample stratification by race and that employment or other subsidies may aid the expansion of caregiving by middle-generation adults.

The economic implications of the racial and ethnic disparities in the use of selective serotonin reuptake inhibitors.

OBJECTIVES: Previous studies have examined racial and ethnic disparities in the use of selective serotonin reuptake inhibitors (SSRI). This study aims to examine the economic implications of these disparities. RESEARCH DESIGN AND METHODS: In this retrospective observational study, the study sample was adult survey respondents with a diagnosis of depression from the Medical Expenditure Panel Survey (2002-2003). SSRI use was measured as the number of times when SSRIs were obtained. The racial and ethnic disparities in SSRI use were examined employing a negative binomial model. The economic implications of disparities were explored using a linear regression with SSRI use as an independent variable. Interaction terms between the variable for SSRI use and dummy variables for racial and ethnic groups were included to explore whether the relationships between SSRI use and health expenditures differ across racial and ethnic groups. RESULTS: The mean number of times of SSRI use was higher for non-Hispanic whites than non-Hispanic blacks (3.02 vs. 1.79; p < 0.05) and Hispanic whites (3.02 vs. 1.68; p < 0.05). These differences were still significant after adjusting for covariates (p < 0.05). In the multivariate analysis, each time of SSRI use was associated with health expenditures of $301 higher. Neither dummy variables for racial and ethnic groups nor the interaction terms between these dummy variables and the variable for SSRI use were significant. CONCLUSIONS: The lower use of SSRIs among minorities compared to non-Hispanic whites is associated with lower health expenditures among minorities. SSRI may be a proxy for improved access to health care due to under-treatment of depression in general. The main limitation of this study is that its observational nature does not allow the researchers to determine whether the association between SSRI use and the increase in health expenditures is a causal effect.

Health insurance disparities in traditional and contingent/alternative employment.

Relative to whites, Hispanics and blacks are less likely to have employer health insurance coverage. We examine whether ethnicity or race affects employment in traditional jobs or in contingent and alternative work arrangements, and whether ethnicity or race affects insurance offer, eligibility, and/or enrollment, conditional on employment sector. Health insurance disparities relative to whites are more pronounced for Hispanics, primarily due to disparities in employment by firms that offer coverage. Eliminating racial/ethnic disparities in offers, eligibility, and takeup would increase insurance coverage rates of Hispanics in traditional jobs and of both Hispanics and blacks in contingent and alternative jobs.

Is there equity in the home health care market? Understanding racial patterns in the use of formal home health care.

OBJECTIVE: This article explores whether the formal home health care (HHC) market is equitable or manifests unexplained racial disparities in use. METHODS: The database is the 1994 National Long Term Care Survey. We estimate logit regression models with a race dummy variable, race interaction terms, and stratification by race. We apply the Oaxaca decomposition technique to quantify whether the observed racial gap in formal HHC use is explained by racial differences in predisposing, enabling, need, and environmental characteristics. RESULT: We find numerous unique racial patterns in HHC use. Blacks with diabetes and low income have higher probabilities of HHC use than their White counterparts. Black older persons have a 25% higher chance of using HHC than Whites. Our Oaxaca analysis indicates that racial differences in predisposing, enabling, need, and environmental characteristics account for the racial gap in use of HHC. DISCUSSION: We find that the HHC market is equitable, enhancing availability, acceptability, and accessibility of care for older Black persons. Thus, the racial differences that we find are not racial disparities.
