Racial and ethnic differences in utilization of health services in patients with diabetes enrolled in medicaid

We evaluated racial and ethnic differences in use of medical care between patients with diabetes enrolled in Medicaid and explored whether differences varied by state Medicaid program. Using data from 137,006 patients we created a multivariable Poisson regression model to examine the effect of race on ambulatory care visits, emergency ward visits, and hospitalization rates for patients with diabetes mellitus enrolled in three state Medicaid programs. We found significant differences in service use between groups, which varied depending on state. For example, black patients compared with whites had significantly fewer outpatient visits but more hospitalizations in New Jersey; by contrast, blacks had higher outpatient visit rates and lower hospitalization rates in Georgia. Racial and ethnic differences in health service use among Medicaid enrollees were not consistent across states, suggesting that local factors, including varied Medicaid policies, may affect racial and ethnic differences in use of health care services.     

Medicaid's role in financing health care for children with behavioral health care needs in the special education system: implications of the Deficit Reduction Act

Background: Recent changes to Medicaid policy may have unintended consequences in the education system. This study estimated the potential financial impact of the Deficit Reduction Act (DRA) on school districts by calculating Medicaid‐reimbursed behavioral health care expenditures for school‐aged children in general and children in special education in particular. Methods: Medicaid claims and special education records of youth ages 6 to 18 years in Philadelphia, PA, were merged for calendar year 2002. Behavioral health care volume, type, and expenditures were compared between Medicaid‐enrolled children receiving and not receiving special education. Results: Significant overlap existed among the 126,533 children who were either Medicaid enrolled (114,257) or received special education (27,620). Medicaid‐reimbursed behavioral health care was used by 21% of children receiving special education (37% of those Medicaid enrolled) and 15% of other Medicaid‐enrolled children. Total expenditures were $197.8 million, 40% of which was spent on the 5728 children in special education and 60% of which was spent on 15,092 other children. Conclusions: Medicaid‐reimbursed behavioral health services disproportionately support special education students, with expenditures equivalent to 4% of Philadelphia’s $2 billion education budget. The results suggest that special education programs depend on Medicaid‐reimbursed services, the financing of which the DRA may jeopardize.     

Children Who Are Medically Fragile in North Carolina: Using Medicaid Data to Estimate Prevalence and Medical Care Costs in 2004

Objectives: The purpose of this paper is to demonstrate a method of using medical insurance paid claims and enrollment data to estimate the prevalence of selected health conditions in a population and to profile associated medical care costs. The examples presented here use North Carolina Medicaid data to produce estimates for children ages 0–19 who are medically fragile. These children with serious health conditions are a small subset of all children with special health care needs. Methods: The children who are medically fragile were identified through selected procedure and durable medical equipment codes. We profiled the expenditures for all medical services provided to these children during 2004. Results: 1,914 children ages 0–19 enrolled in Medicaid were identified as medically fragile (0.22 percent). The amount paid by Medicaid for these children during 2004 for all medical services was $133.8 million, or $69,906 per child. By comparison, the average expenditure by Medicaid during 2004 for a randomly selected group of children receiving well-child care visits was $3,181 per child. The $133.8 million of Medicaid expenditures for the children who are medically fragile represents 6.8 percent of the nearly $2 billion spent by Medicaid in 2004 for all medical services for all children ages 0–19. Conclusions: This study presents a standard methodology to identify children with specific health conditions and describe their medical care costs. Our example uses Medicaid claims and enrollment data to measure prevalence and costs among children who are medically fragile. This approach could be replicated for other health care payer data bases and also in other geographic areas.     

Suppression of racial disparities for children with special health care needs among families receiving Medicaid

This study examines whether the US public health insurance program Medicaid suppresses racial disparities in parental identification of service needs of their children with special health care needs (CSHCN). We analyze data from the 2001 US National Survey of CSHCN (n = 14,167 children). We examine three outcomes which were parental identification of (a) the child's need for professional care coordination, (b) the child's need for mental health services, and (c) the family's need for mental health services. A suppression analysis, which is a form of mediation analysis, was conducted. Our results show a disparity, reflected in a negative direct effect of race for all three outcomes: Black parents of CSHCN are less likely to report a need for services than White parents of CSHCN and Medicaid coverage was associated with reduced racial disparities in reporting the need for services. These analyses suggest receipt of Medicaid is associated with a suppression of racial disparities in reported need for services.     

Racial and ethnic differences in parents' assessments of pediatric care in Medicaid managed care

OBJECTIVE: This study examines whether parents' reports and ratings of pediatric health care vary by race/ethnicity and language in Medicaid managed care. DATA SOURCES: The data analyzed are from the National Consumer Assessment of Health Plans (CAHPS) Benchmarking Database 1.0 and consist of 9,540 children enrolled in Medicaid managed care plans in Arkansas, Kansas, Minnesota, Oklahoma, Vermont, and Washington state from 1997 to 1998. DATA COLLECTION: The data were collected by telephone and mail, and surveys were administered in Spanish and English. The mean response rate for all plans was 42.1 percent. STUDY DESIGN: Data were analyzed using multiple regression models. The dependent variables are CAHPS 1.0 ratings (personal doctor, specialist, health care, health plan) and reports of care (getting needed care, timeliness of care, provider communication, staff helpfulness, plan service). The independent variables are race/ethnicity (white, African American, American Indian, Asian, and Hispanic), Hispanic language (English or Spanish), and Asian language (English or other), controlling for gender, age, education, and health status. PRINCIPAL FINDINGS: Racial/ethnic minorities had worse reports of care than whites. Among Hispanics and Asians language barriers had a larger negative effect on reports of care than race/ethnicity. For example, while Asian non-English-speakers had lower scores than whites for staff helpfulness (beta = -20.10), timeliness of care (beta = -18.65), provider communication (beta = -17.19), plan service (beta = -10.95), and getting needed care (beta = -8.11), Asian English speakers did not differ significantly from whites on any of the reports of care. However, lower reports of care for racial/ethnic groups did not translate necessarily into lower ratings of care. CONCLUSIONS: Health plans need to pay increased attention to racial/ethnic differences in assessments of care. This study's finding that language barriers are largely responsible for racial/ethnic disparities in care suggests that linguistically appropriate health care services are needed to address these gaps.     

Differences in Mental Health Service Sector Utilization among African American and Caucasian Youth Entering Systems of Care Programs

Differences in unmet need and access to services between African American and Caucasian youth have been established; less is known about differences in specific mental health service sectors. This study examined differences in past year outpatient, school-based, day treatment and residential/inpatient service utilization among African American and Caucasian youth (n = 3,649) entering a federally funded system of care program. Random effect logistic regression models were implemented to examine the relationship between race and past year service utilization. Analyses revealed that African American youth were less likely than Caucasian youth to have utilized school-based and residential/inpatient mental health services in the past year. Findings suggest that racial disparities exist in service use for certain types of service sectors and highlight the importance of understanding and identifying individual, family, and community factors that contribute to disparities in service utilization.     

Factors associated with Medicaid enrollment for low-income children in the United States

This study analyzes the 1996-1997 Community Tracking Study Household Survey to identify factors associated with Medicaid enrollment for low-income children and to examine the differences between those enrolled in the Medicaid program and those who were eligible but uninsured. We estimated that 17.4% of Medicaid-eligible children were uninsured. Medicaid eligible children who were younger, African American, with single parents, with AFDC eligible parents, with no parent employed full-time were more likely to be enrolled in the Medicaid program. Children with better health status were less likely to be enrolled in Medicaid. In addition, children whose parents were uninsured were more likely not to be enrolled in Medicaid.     

Transportation brokerage services and Medicaid beneficiaries' access to care

Objective. To examine the effect of capitated transportation brokerage services on Medicaid beneficiaries' access to care and expenditures.
Data Sources/Study Setting. The study period from 1996 to 1999 corresponds to the period of a natural experiment during which Georgia and Kentucky implemented transportation brokerage services. Effects were estimated for asthmatic children and diabetic adults.
Study Design. We used difference-in-differences models to assess the effects of transportation brokerage services on access to care, measured by Medicaid expenditures and health services use. The study design is strengthened by the staggered implementation dates between states and within each state.
Principal Findings. For asthmatic children, transportation brokerage services increased nonemergency transportation expenditures and the likelihood of using any services; reductions in monthly expenditures more than offsetting the increased transportation costs. For diabetic adults, nonemergency transportation costs decreased despite increased monthly use of health services; average monthly medical expenditures and the likelihood of hospital admission for an ambulatory care-sensitive condition (ACSC) also decreased.
Conclusions. The shift to transportation brokerage services improved access to care among Medicaid beneficiaries and decreased the expenditures. The increase in access combined with reduced hospitalizations for asthmatic children and ACSC admissions for diabetic adults are suggestive of improvements in health outcomes.     

Racial and Ethnic Disparities in the Continuation of Community-Based Children’s Mental Health Services

This paper examines racial and ethnic disparities in continuation of mental health services for children and youth in California and how English language proficiency moderates the effect of race/ethnicity on the continuation of service. While previous research indicated racial/ethnic or geographic disparities in accessing mental health services among children and youth, few studies specifically focused on the continuation of mental health care. The authors used administrative data from California county mental health services users under age 25. Applying logistic regression, English language proficiency was found to be the major determinant of continuation of mental health services in this age group. With the exception of children of Asian descent, non-English speaking children and youth of diverse racial/ethnic background were significantly less likely to continue receiving mental health services compared with White English-speaking peers, even after controlling for sociodemographic, clinical and county characteristics.     

An Episode-Based Framework for Analyzing Health Care Expenditures: An Application of Reward Renewal Models

Objective. To illustrate an episode-based framework for analyzing health care expenditures based on reward renewal models, a stochastic process used in engineering for describing processes that cycle on and off with "rewards" (or costs) occurring at the end of each cycle.
Data Sources/Study Setting. Data used in the illustration were collected as part of an evaluation of a national initiative to improve mental health services for children and youth. Participants were enrolled in a longitudinal study at a demonstration site and in a comparison community between 1997 and 1999. The illustration involves analyses of mental health expenditures at the two sites and of the dynamics of service use behind those expenditures.
Data Collection/Extraction Methods. Services data were derived from management information systems as well as patient records at inpatient facilities in the two communities. These data cover services received between 1997 and 2003. The analysis focuses on the year following study entry.
Principal Findings. Between-site differences in expenditures reflect complex between-site differences in the timing of service use. In particular, children at the demonstration stayed in treatment longer but were less likely to return for treatment later. In contrast, children at the comparison site experienced substantially less continuity of care. Costs per day of treatment within an episode were comparable at the two sites.
Conclusions. Reward renewal models offer a promising means for integrating research on service episodes and the dynamics of service use with that on health care expenditures.     

Health Promotion and Psychosocial Services and Women’s Assessments of Interpersonal Prenatal Care in Medicaid Managed Care

Objectives: If prenatal health promotion and psychosocial support services are to remain accessible to Medicaid eligible women, evidence is needed as to whether the services improve care and benefit women in ways that matter to health plans. The aims of this study are to determine whether prenatal health promotion and psychosocial services are associated with better interpersonal care and greater satisfaction with care; and whether the effects on interpersonal care help explain satisfaction with care. Research Design: A telephone survey of 363 African American, Latina (US and nonUS-born) and White women receiving prenatal care in four Medicaid public health plans in California in 2001. Multivariate regression analyses were done with adjustments for potentially confounding variables. Measures: Independent variables included dichotomous variables for health promotion advice (five separate areas) and composite scales for psychosocial assessment (six areas combined). Dependent variables included satisfaction with care, and indices for interpersonal care (communication, decision-making, and interpersonal style). Results: Women who report receiving health promotion or psychosocial services also report receiving better interpersonal care and rate their satisfaction with care higher. Receiving either type of support service is associated with higher quality communication, decision-making and interpersonal style. The effects of the support services on satisfaction are, in turn, explained by the effects on interpersonal care. Conclusions: Prenatal health promotion and psychosocial services have associated benefits to enrollees that should matter to Medicaid health plans and their providers.     

Racial differences in Norplant use in the United States

The introduction of the contraceptive implant Norplant has focused attention on how social factors may affect contraceptive use. In the United States, race is a central category of social organization which may impact Norplant use. I use data from the 1995 National Survey of Family Growth to answer three main questions. (1) Are women of color more likely to use Norplant? (2) To what extent can racial differences in Norplant use be explained by a structural bias in the provision of medical care? (3) To what extent can racial differences in Norplant use be explained by life circumstances which may affect individual women's contraceptive decisions? I find that African American and Native American women are more likely than white or Asian American women to be recent Norplant users. There are no differences in recent use by Hispanic origin. Both a structural bias in the provision of care and differences in life circumstances account for the disparity in Norplant use between African Americans and whites. However, none of the factors examined here explain Native American women's high rate of use. Concerns about health risks for Norplant use are also discussed. These findings point out the importance of examining structural, individual and health status factors in studies of the use of health services.     

Racial differences in cardiac catheterization as a function of patients' beliefs

OBJECTIVES: We examined racial differences in cardiac catheterization rates and reviewed whether patients' beliefs or other variables were associated with observed disparities. METHODS: We did a prospective observational cohort study of 1045 White and African American patients at 5 Veterans Affairs (VA) medical centers whose nuclear imaging studies indicated reversible cardiac ischemia. RESULTS: There were few demographic differences between White and African American patients in our sample. African Americans were less likely than Whites to undergo cardiac catheterization. African Americans were more likely than Whites to indicate a strong reliance on religion and to report racial and social class discrimination and were less likely to indicate a generalized trust in people but did not differ from White patients on numerous other attitudes about health and health care. Neither sociodemographic or clinical characteristics nor patients' beliefs explained the observed disparities, but physicians' assessments of the procedure's importance and patients' likelihood of coronary disease seemed to account for differences not otherwise explained. CONCLUSIONS: Patients' preferences are not the likely source of racial disparities in the use of cardiac catheterization among veterans using VA care, but physicians' assessments warrant further attention.     

Does race influence age of diagnosis for children with developmental delay?

BackgroundEarly identification of developmental delay is important for ensuring that children receive the early intervention services they need. Racial disparities exist for a number of childhood conditions, but it is not known whether there are racial disparities in the age of diagnosis with developmental delay.Objective/HypothesisThis study aimed to determine the mean age of diagnosis with developmental delay for children ensured by South Carolina Medicaid. We hypothesized that African American children would be diagnosed later than white children.MethodsA retrospective cohort study design explored South Carolina Medicaid claim records to determine the age when 5358 children with developmental delay (DD) were first diagnosed and whether there were racial disparities in age of diagnosis.ResultsThe mean age at diagnosis was 4.08 years for African American children and 4.27 years for white children. For children diagnosed with DD and mental retardation, the average age of first diagnosis was 2.6 years, and for children with DD plus cerebral palsy, the average age was 2.1 years. African American race was significantly associated with younger diagnosis with DD in a multivariable model, but the overall model explained little of the variation in age at diagnosis.ConclusionsThere were no clinically significant racial differences in the mean age of diagnosis with developmental delay. However, in general the age of diagnosis was undesirably late for both groups. Additional efforts are needed to ensure that children with DD, living in South Carolina, are identified near the beginning of early intervention services.     

Racial and Ethnic Disparities in the Use of Mental Health Services

The authors used data from the 1998-1999 Community Tracking Study (CTS) household survey to examine variations in predictors of use of mental health services among different racial and ethnic groups (white, African American, Hispanic, and other). African Americans and Hispanics were less likely to have visited a mental health professional (MHP) in the prior year than were whites. Independent of health insurance and health status, low- to middle-income African Americans may be at particular risk for inadequate use of an MHP compared to higher-income African Americans. Similarly, upper-income Hispanics were more likely to have visited an MHP than Hispanics in the lowest income range. Adults aged 50 and older were less likely to visit an MHP than individuals aged 18-49. Depressed men were more likely to visit an MHP than depressed women. Efforts to reduce disparities should focus on lower-income racial and ethnic minorities.     

Children's mental health care: differences by race/ethnicity in urban/rural areas

This study examines racial/ethnic disparities in children's mental health and the receipt of mental health services, and whether those disparities differ between urban and rural areas. We find no significant difference between racial/ethnic groups in the prevalence of child mental health problems in either urban or rural areas. However, there are disparities in the use of mental health services. Hispanic children and Black children in urban areas receive less mental health care than their White counterparts, and the disparity persists for Hispanic children in rural areas, even after controlling for other relevant factors. Initiatives to improve access to mental health care for racial/ethnic minorities should recognize these disparities, and address the lack of culturally appropriate services in both urban and rural areas. In addition, outreach should raise awareness among parents, teachers, and other community members concerning the need for mental health services for minority children.     

Racial Disparities in Economic and Clinical Outcomes of Pregnancy Among Medicaid Recipients

To explore racial-ethnic disparities in adverse pregnancy outcomes among Medicaid recipients, and to estimate excess Medicaid costs associated with the disparities. Cross-sectional study of adverse pregnancy outcomes and Medicaid payments using data from Medicaid Analytic eXtract files on all Medicaid enrollees in fourteen southern states. Compared to other racial and ethnic groups, African American women tended to be younger, more likely to have a Cesarean section, to stay longer in the hospital and to incur higher Medicaid costs. African-American women were also more likely to experience preeclampsia, placental abruption, preterm birth, small birth size for gestational age, and fetal death/stillbirth. Eliminating racial disparities in adverse pregnancy outcomes (not counting infant costs), could generate Medicaid cost savings of $114 to $214 million per year in these 14 states. Despite having the same insurance coverage and meeting the same poverty guidelines for Medicaid eligibility, African American women have a higher rate of adverse pregnancy outcomes than White or Hispanic women. Racial disparities in adverse pregnancy outcomes not only represent potentially preventable human suffering, but also avoidable economic costs. There is a significant financial return-on-investment opportunity tied to eliminating racial disparities in birth outcomes. With the Affordable Care Act expansion of Medicaid coverage for the year 2014, Medicaid could be powerful public health tool for improving pregnancy outcomes.
