Health care disparities in disadvantaged Medicare beneficiaries: a national project review

The wealth of literature documenting differences in health care utilization by race and ethnicity underscores the need to develop a system to effectively measure health care related disparities. The Centers for Medicare & Medicaid Services has taken the first steps toward detailing the quality of care for fee-for-service (FFS) Medicare beneficiaries. Using data collected for the two-period 1997-1999 on a cross-section of beneficiaries from all states and territories of the U.S., quality was measured using a set of 24 indicators of care. The results of this effort were reported in the October 4, 2000 issue of the Journal of the American Medical Association. This article reports similar measures of quality but focuses specifically on disparities in the indicators among five disadvantaged Medicare beneficiary groups: African-American, American Indian/Alaska Natives, Asian/Pacific Islanders, Hispanics, and Medicare beneficiaries enrolled in Medicaid (dually enrolled). These indicators serve as a baseline for tracking quality improvement within disadvantaged populations and evaluating the success of efforts to reduce health care disparities at the national level. The findings suggest that patterns of disparities exist in both the inpatient and outpatient settings for disadvantaged beneficiaries. Over the next decade, the composition of Medicare beneficiaries will become more diverse. This increasing diversity makes it imperative to identify and monitor the existence and extent of health care disparities. The consistent and ongoing evaluation of racial, ethnic, and socioeconomic disparities should provide an incentive to create effective preventive programs tailored to specific community needs.     

Trends in care practices and outcomes among Medicare beneficiaries with diabetes

BACKGROUND: While diabetes is a major issue for the aging U.S. population, few studies have described the recent trends in both preventive care practices and complications among the Medicare population with diabetes. Using the Medicare Quality Monitoring System (MQMS), this 2004 study describes these trends from 1992 to 2001 and how these rates vary across demographic subgroups. METHODS: Outcomes include age- and gender-adjusted rates of 15 indicators associated with diabetes care from 1992 to 2001, the absolute change in rates from 1992 to 2001, and 2001 rates by demographic subgroups. The data were cross-sectional samples of Medicare beneficiaries with diabetes from 1992 to 2001 from the Medicare 5% Standard Analytic Files. RESULTS: Use of preventive care practices rose from 1992 to 2001: 45 percentage points for HbA1c tests, 51 for lipid tests, 8 for eye exams, and 38 for self-monitoring of glucose levels (all p<0.05). Rates for short-term and some long-term complications of diabetes (e.g., lower-extremity amputations and cardiovascular conditions) fell from 1992 to 2001 (p<0.05). However, rates of other long-term complications such as nephropathy, blindness, and retinopathy rose during the period (p<0.05). Nonwhites and beneficiaries aged <65 and >85 exhibited consistently higher complication rates and lower use of preventive services. CONCLUSIONS: The Medicare program has seen some significant improvement in preventive care practices and significant declines in lower-limb amputations and cardiovascular conditions. However, rates for other long-term complications have increased, with evidence of subgroup disparities. The MQMS results provide an early warning for policymakers to focus on the diabetes care provided to some vulnerable subgroups.     

Improving care and interactions with racially and ethnically diverse populations in healthcare organizations

The need for healthcare managers to develop strategies that address culturally appropriate care for racial and ethnic populations continues to grow in importance. Healthcare organizations within the United States serve a range of diverse people, but they are not adequately meeting the needs of specific populations. Cultural and linguistic barriers are posing problems for an industry that is already financially strained. If strategies to provide more culturally appropriate care are not implemented, financial pressures will continue to rise and quality of care will suffer. Healthcare organizations can and should promote cultural competence among their physicians and employees. This article attempts to define the scope of the problem through literature and case studies. It also offers healthcare managers strategies for improving cultural understanding and competency within their organization.     

The economic implications of self-care: the effect of lifestyle, functional adaptations, and medical self-care among a national sample of Medicare beneficiaries

OBJECTIVES: Self-care includes actions taken by individuals to promote or ensure their health, to recover from diseases or injuries, or to manage their effects. This study measured associations between self-care practices (lifestyle practices, adaptations to functional limitations, and medical self-care) and Medicare expenditures among a national sample of adults 65 years and older. METHODS: Regression models of Medicare use and expenditures were estimated by using the National Survey of Self-Care and Aging and Medicare claims for 4 years following a baseline interview. RESULTS: Lifestyle factors (swimming and walking) and functional adaptations (general home modifications) were associated with reductions in monthly Medicare expenditures over a 12-month follow-up period. Expenditure reductions were found over the 48-month follow-up period for participation in active sports, gardening, and medical self-care. Practices associated with increases in expenditures included smoking, physical exercise (possibly of a more strenuous nature), and specific home modifications. CONCLUSIONS: Certain self-care practices appear to have significant implications for Medicare expenditures and presumptively for the health status of older adults. Such practices should be encouraged among older adults as a matter of national health policy.     

Primary care for urban adolescent girls from ethnically diverse populations: foregone care and access to confidential care

Adolescent girls face unique challenges in health care utilization, which can result in unmet needs. We sought to describe settings of usual care and primary care use, and to identify predictors of foregone care and experience of confidential care in a primarily racial/ethnic minority low-income sample. We conducted an anonymous computer-assisted self-administered survey of 9th-12th grade girls (n=819) in three Bronx public high schools, the majority of whom were Hispanic (69.8%) and Black (21.4%). Most (80%) reported having a usual source of care. Of these, 77.2% had a regular doctor. Those least likely to have a usual source of care were non-U.S. born girls (73.1% vs. 83.1%) and less acculturated girls. Predictors of foregone care in the last year include being sexually active, poor family social support, and low self esteem. Predictors of access to confidential care at last visit were age, self-efficacy for confidential care, having a regular doctor, setting of care, and having had a recent physical exam. Many urban adolescent girls, especially non-U.S. born girls, lack a usual source of care and regular health care provider. Continued attention to reducing both financial and non-financial barriers to care is required to ensure access to and quality of care for diverse populations.     

Managed care and medical expenditures of Medicare beneficiaries

This paper investigates the impact of Medicare HMO penetration on the medical care expenditures incurred by Medicare fee-for-service (FFS) enrollees. We find that increasing penetration leads to reduced spending on FFS beneficiaries. In particular, our estimates suggest that the increase in HMO penetration during our study period led to approximately a 7% decline in spending per FFS beneficiary. Similar models for various measures of health care utilization find penetration-induced reductions consistent with our spending estimates. Finally, we present evidence that suggests our estimated spending reductions are driven by beneficiaries who have at least one chronic condition.     

Health behaviors and quality of care among Latinos with diabetes in managed care

OBJECTIVES: We evaluated whether ethnicity and language are associated with diabetes care for Latinos in managed care. METHODS: Using data from 4685 individuals in the Translating Research Into Action for Diabetes (TRIAD) Study, a multicenter study of diabetes care in managed care, we constructed multivariate regression models to compare health behaviors, processes of care, and intermediate outcomes for Whites and English- and Spanish-speaking Latinos. RESULTS: Latinos had lower rates of self-monitoring of blood glucose and worse glycemic control than did Whites, higher rates of foot self-care and dilated-eye examinations, and comparable rates of other processes and intermediate outcomes of care. CONCLUSIONS: Although self-management and quality of care are comparable for Latinos and Whites with diabetes, important ethnic disparities persist in the managed care settings studied.     

Drug coverage,utilization, and spending by Medicare beneficiaries with heart disease

For Medicare beneficiaries who report having heart disease, drug coverage and type of supplemental health insurance affect the likelihood of usage and costs of heart medications, but not the extent of usage. Nearly one in five does not use heart medications and of the latter, one-third lack drug coverage. Some non-users without drug coverage go without prescribed heart medications because of limited financial access. Compared to non-users with coverage, they utilize medical provider services more, and if hospitalized, their inpatient costs are twice as high. Medicare may accrue cost savings by providing drug coverage to and monitoring these at-risk beneficiaries.     

Health insurance and health at age 65: implications for medical care spending on new Medicare beneficiaries

OBJECTIVES: To investigate the consequences of endogeneity bias on the estimated effect of having health insurance on health at age 63 or 64, just before most people qualify for Medicare, and to simulate the implications for total and public insurance (Medicare and Medicaid) spending on newly enrolled beneficiaries in their first years of Medicare coverage. DATA: The longitudinal Health and Retirement Survey of people who were 55-61 years old in 1992, followed through biannual surveys to age 63-64 or until 2000 (whichever came first), and those who were 66-70 years olds from the Medicare Current Beneficiary Surveys, 1992-1998. STUDY DESIGN: Instrumental variable (IV) estimation of a simultaneous equation model of insurance choice and health at age 63-64 as a function of baseline health and sociodemographic characteristics in 1992 and endogenous insurance coverage over the observation period. FINDINGS: Continuous insurance coverage is associated with significantly fewer deaths prior to age 65 and, among those who survive, a significant upward shift in the distribution of health states from fair and poor health with disabilities to good to excellent health. Treating insurance coverage as endogenous increases the magnitude of the estimated effect of having insurance on improved health prior to age 65. The medical spending simulations suggest that if the near-elderly had continuous insurance coverage, average annual medical spending per capita for new Medicare beneficiaries in their first few years of coverage would be slightly lower because of the improvement in health status. In addition, total Medicare and Medicaid spending for new beneficiaries over their first few years of coverage would be about the same or slightly lower, even though more people survive to age 65. CONCLUSIONS: Extending insurance coverage to all Americans between the ages of 55 and 64 would improve health (increase survival and shift people from good-fair-poor health to excellent-very good health) at age 65, and possibly reduce total short-term spending by Medicare and Medicaid for newly eligible Medicare beneficiaries, even though more people would enter the program because of increased survival.     

Access to care and satisfaction with care among fee-for-service Medicare beneficiaries by level of care need

BackgroundVariation among fee-for-service (FFS) Medicare beneficiaries by level of care need for access to care and satisfaction with care is unknown.ObjectiveWe examined access to care and satisfaction with care among FFS Medicare beneficiaries by level of care need.MethodsWe employed a cross-sectional study design. Using the Medicare Current Beneficiary Survey, we categorized 17,967 FFS Medicare beneficiaries into six groups based on level of care need: the relatively healthy (11.0%), those with simple chronic conditions (26.1%), those with minor complex chronic conditions (28.6%), those with major complex chronic conditions (14.2%), the frail (6.2%), and the non-elderly disabled or end-stage renal disease (ESRD) (13.9%). Outcome measures included multiple indicators for access to care and satisfaction with care. For each outcome, we conducted a linear probability model while adjusting for individual-level and county-level characteristics and estimated the adjusted value of the outcome by level of care need.ResultsThe non-elderly disabled or ESRD were more likely to experience limited access to care and poor satisfaction with care than other five care need groups. Particularly, the rates of reporting trouble accessing needed medical care were the highest among the non-elderly disabled or ESRD (12.4% [95% CI: 9.6–15.3] vs. 2.1 [95% CI: 1.5–2.8] to 2.5 [95% CI: 1.6–3.5]). The leading reason for trouble accessing needed care among the non-elderly disabled or ESRD was attributable to affordability (59.6%).ConclusionsPolicymakers need to develop targeted approaches to improve access to care and satisfaction with care for the non-elderly with a disability or ESRD.     

Health care utilization in HMO''S : Results from two national samples

HMO's have been endorsed as a means of containing medical care costs. This study is the first use of a national data set to analyze whether HMO's have lower utilization. Regression and logit analyses are used to control for demographic and health status variables. The point estimates confirm that HMO's cut hospital days relative to conventional insurance (e.g., Blue Cross), but imprecision is a serious problem.     

Use of home health care by ESRD and Medicare beneficiaries

The use of home health care (HHC) services among Medicare end stage renal disease (ESRD) enrollees remains an under-studied area. In this article, the authors report sociodemographic characteristics and patterns of HHC utilization by Medicare-covered ESRD patients. The authors found that those who were female, age 85 or over, diabetic, and residing in the New England or West South Central census divisions were more likely to use HHC services and were also more intensive users. Analysis of use patterns in such high-risk populations is necessary to ensure that health policy changes do not have unintended consequences for vulnerable patients.     

Voluntary disenrollment from Medicare managed care: market factors and disabled beneficiaries

Disenrollment rates from Medicare managed care plans have been reported to the public as an indicator of health plan quality. Previous studies have shown that voluntary disenrollment rates differ among vulnerable subgroups, and that these rates can reflect patient care experiences. We hypothesized that disabled beneficiaries may be affected differently than other beneficiaries by competitive market factors, due to higher expected expenditures and impaired mobility. Findings suggest that disabled beneficiaries are more likely to experience multiple problems with managed care.     

Care coordination and telemedicine improves glycaemic control in ethnically diverse veterans with diabetes

We conducted a pilot study of a care-coordination programme involving daily monitoring and education of elderly diabetic veterans from different racial/ethnic groups. A telephone-based, in-home messaging device was used for patient monitoring and education. Sixty-nine patients were enrolled in the study and HbA(1c) values were obtained both before and after the telemedicine intervention in 41 of them. The mean HbA(1c) before enrolment was 7.6% and the mean value 9 months later was 7.3% (P = 0.09). The greatest fall in HbA(1c) occurred in African-Americans (0.65%, P = 0.05). The total number of hospital admissions decreased from 31 pre-enrolment to 25 post-enrolment (P = 0.0002). Bed days of care decreased from 368 to 149 (P = 0.0002). Care coordination, facilitated by telemedicine, appeared to improve glycaemic control in veterans with diabetes from diverse ethnic backgrounds, particularly African-Americans. This may reduce health-care resource utilization.     

Emergency care with lay responders in underserved populations: a systematic review

ObjectiveTo assess the individual and community health effects of task shifting for emergency care in low-resource settings and underserved populations worldwide.MethodsWe systematically searched 13 databases and additional grey literature for studies published between 1984 and 2019. Eligible studies involved emergency care training for laypeople in underserved or low-resource populations, and any quantitative assessment of effects on the health of individuals or communities. We conducted duplicate assessments of study eligibility, data abstraction and quality. We synthesized findings in narrative and tabular format.FindingsOf 19 308 papers retrieved, 34 studies met the inclusion criteria from low- and middle-income countries (21 studies) and underserved populations in high-income countries (13 studies). Targeted emergency conditions included trauma, burns, cardiac arrest, opioid poisoning, malaria, paediatric communicable diseases and malnutrition. Trainees included the general public, non-health-care professionals, volunteers and close contacts of at-risk populations, all trained through in-class, peer and multimodal education and public awareness campaigns. Important clinical and policy outcomes included improvements in community capacity to manage emergencies (14 studies), patient outcomes (13 studies) and community health (seven studies). While substantial effects were observed for programmes to address paediatric malaria, trauma and opioid poisoning, most studies reported modest effect sizes and two reported null results. Most studies were of weak (24 studies) or moderate quality (nine studies).ConclusionFirst aid education and task shifting to laypeople for emergency care may reduce patient morbidity and mortality and build community capacity to manage health emergencies for a variety of emergency conditions in underserved and low-resource settings.
