Quality of diabetes care for adults with physical disabilities in Kansas

BackgroundSimilar to health disparities found among racial and ethnic minority groups, individuals with physical disabilities experience a greater risk for diabetes than those without disabilities.ObjectiveThe purpose of this works was to assess Kansas Medicaid data to determine the quality of diabetic care and the level to which individuals with physical disabilities' prevention and diabetes management needs are being met.MethodsWe selected a continuously eligible cohort of adults (ages 18 and older) with physical disabilities who had diabetes and received medical benefits through Kansas Medicaid. We examined their quality of care measures (screening for HbA1c/glucose, cholesterol, and eye exams; and, primary care visits) in the succeeding year. Using unconditional logistic regression, we assessed the measures for quality of care as they related to demographic variables and comorbid hypertension.ResultsThirty-nine percent of the 9,532 adults with physical disabilities had diabetes. They had the following testing rates: HbA1c, 82.7%; cholesterol, 51.5%; and eye examinations, 86.8%. Females, those with dual eligibility, and those with comorbid hypertension had higher rates for all types of screenings and primary care visits. Those living in MUAs had a higher screening rate for cholesterol.ConclusionsAdults with physical disabilities supported by Kansas Medicaid received diabetes quality indicator screenings have better diabetes quality of care rates for 3 out of 4 measures than nationally published figures for Medicaid. These findings point to a strong quality of care programs in Kansas for this population; however an imperative next step is to determine how effectively this population is managing their blood sugar levels day-to-day.     

US primary care delivery after the Health Center Growth Initiative: comparison of health centers, hospital outpatient departments, and physicians' offices

We compared patient management during primary care visits in 3 settings (health centers, hospital outpatient departments, and physicians' offices) and investigated racial/ethnic and insurance-based disparities in the wake of the recent health center program expansion. Within health centers, there were few differences in patient management across racial/ethnic or insurance groups. In contrast, the other settings displayed more racial/ethnic and insurance disparities in patient management during visits. Health centers performed processes of care with comparable or higher occurrence, relative to physicians' offices. Health care disparities were also attenuated in health centers, compared with other primary care settings.     

Associations between Outpatient and Inpatient Service Use among Persons with HIV Infection: A Positive or Negative Relationship?

Objective. To examine the prospective association between frequency of outpatient visits and subsequent inpatient admissions.
Data Sources. Medical record data on 13,942 patients with HIV infection seen in 10 HIV speciality care sites across the United States.
Study Design. This observational study followed a cohort of HIV-infected patients who were in care in the first half of 2001. Numbers of inpatient admissions and outpatient visits were calculated for each patient for each 3-month period, from 2001 through 2004.
Analysis. Negative binomial and logistic regression analyses using random-effects models examined the effects of inpatient admissions and outpatient visits in the previous period on inpatient and outpatient service utilization, controlling for background characteristics and HIV disease stage.
Results. For 3-month periods, between 5 and 9 percent of patients had an inpatient admission. The linear association between number of outpatient visits and any inpatient admission in the subsequent period was positive (adjusted odds ratio=1.05; 95 percent confidence interval [CI]=1.04, 1.06). However, patients with zero prior outpatient visits had significantly greater admission rates than those with one prior visit. Hospitalization rates were also higher among those with a prior hospitalization and those with more advanced HIV disease.
Conclusions. These results suggest a J-shaped relationship between outpatient use and inpatient use among persons with HIV disease. Those in worse health have greater utilization of both inpatient and outpatient care. However, having no outpatient visits may also increase the likelihood of subsequent hospitalization. Although outpatient care cannot be justified as a cost-saving mechanism, maintaining regular clinical monitoring of patients is important.     

The Use of Health Care Services by People With Diabetes in Rural Areas

Abstract: Current standards of health care support the view that diabetes can be managed in an outpatient setting, thereby preventing costly hospitalization. Yet, recent studies on access to care suggest that rural residents do not receive the same services for diabetes care as their urban counterparts. This study identifies differences in use for three types of services-hospital care, home health visits, and physician office visits—by geographical location. Using a sample of 6,698 Medicare beneficiaries, the authors performed multivariate analysis of variance to test the influence of geographical differences on each type of service use after controlling for the other types of service use and individual factors. Results showed significant differences among the geographical categories, with diabetic individuals in the most sparsely populated communities reporting fewer physician office visits and more home health visits than their urban counterparts. Because this pattern may have a negative impact on health outcomes, additional research is needed to determine the optimal array of services necessary to manage chronic diseases, such as diabetes, in rural areas.     

Medicaid Managed Care and Health Care for Children

Objective. Many states expanded their Medicaid managed care programs during the 1990s, causing concern about impacts on health care for affected populations. We investigate the relationship between Medicaid managed care enrollment and health care for children.
Data Sources and Measures. Repeated cross-sections of Medicaid-covered children under 18 years of age from the 1996/1997 and 1998/1999 Community Tracking Study Household Surveys ( n =2,602) matched to state-year CMS Medicaid managed care enrollment data. For each individual, we constructed measures of health care utilization (provider and emergency department visits, hospitalizations, surgeries); health care access (usual source of care, unmet medical needs, put-off needed care); and satisfaction (satisfaction overall, with doctor choice, and with last visit).
Study Design. Regression analysis of the relationship between within-state changes in Medicaid managed care enrollment rates and changes in mean utilization, access, and satisfaction measures for children covered by Medicaid, controlling for a range of potentially confounding factors.
Principal Findings. Increases in Medicaid health maintenance organization (HMO) enrollment are associated with less emergency room use, more outpatient visits, fewer hospitalizations, higher rates of reporting having put off care, and lower satisfaction with the most recent visit. Medicaid primary care case management (PCCM) plans are associated with increases in outpatient visits, but also with higher rates of reporting unmet medical needs, putting off care, and having no usual source of care.
Conclusions. Both Medicaid HMO and PCCM plans can have important impacts on health care utilization, access, and satisfaction. Some impacts may be positive (e.g., less ED use and more outpatient provider use), although concern about increasing challenges in access to care and satisfaction is also warranted.     

Differences in Use of Health Services Between White and African American Children Enrolled in Medicaid in North Carolina

Objectives: Racial differences in health status and use of health services persist in the United States and are not completely explained by differences in socioeconomic status. This study examines differences in use of health services between White and African American children enrolled in Medicaid, controlling for other factors that affect service use. We make comparisons for use of primary preventive services, diagnosis and treatment of selected common childhood illnesses, and Medicaid expenditures. Methods: We linked Medicaid enrollment records, Medicaid paid claims data, and data on use of child WIC services to birth certificates for NorthCarolina children born in 1992 to measure use of health services and Medicaid expenditures by race for children ages 1, 2, 3, and 4. Logistic and Tobit regression models were used to estimate the independent effect ofrace, controlling for other variables such as low birth weight, WICparticipation, and mother's age, education, and marital status. Since allchildren enrolled in Medicaid are in families of relatively low income, racial differences in socioeconomic status are partially controlled.Results: African American children had consistently lower Medicaidexpenditures and lower use of health servicesthan did White children,after statistically controlling for other maternal and infantcharacteristics that affect health service use, including child WICparticipation. For example, total annual Medicaid expenditures were $207–303 less for African American children than for White children,controlling for other variables. African America children were significantly less likely to receive well-child and dental services than were White children. Conclusions: African American children enrolled in Medicaid use healthservices much less than White children, even when controlling forsocioeconomic status and other factors that affect service use. Linkingstate administrative databases can be a cost-effective way of addressingimportant issues such as racial disparities in health service use.     

Racial Disparities in Access to Care for Men in a Public Assistance Program for Prostate Cancer

California's IMPACT program provides all its enrollees with health insurance and social service resources. We hypothesized that racial/ethnic disparities in access to care might be attenuated among men served by this program. Our objective was to evaluate racial/ethnic differences in health services utilization and patient-reported health care outcomes among disadvantaged men in a prostate cancer public-assistance program, and to identify modifiable factors that might explain persistent disparities in this health care setting. We performed a retrospective cohort study of 357 low-income men enrolled in IMPACT from 2001 through 2005. We evaluated realized access to care with two health services utilization measures: (1) use of emergency department care without hospitalization and, (2) frequency of prostate-specific antigen testing. We also measured two patient-experience outcomes: (1) satisfaction with care received from IMPACT, and (2) confidence in IMPACT care providers. We observed significant bivariate associations between race/ethnicity and patient-experience outcomes (P < 0.05), but not utilization measures. In multivariable models, Hispanic men were more likely than white men to report complete satisfaction with health care received in IMPACT (adjusted OR = 5.15, 95% CI 1.17-22.6); however, the association between race/ethnicity and satisfaction was not statistically significant (P = 0.11). Language preference and self-efficacy in patient-physician interactions are potentially-modifiable predictors of patient-experience outcomes. We observed no racial/ethnic disparities in health services utilization among disadvantaged men served by a disease-specific public assistance program. The greater satisfaction and confidence among Hispanic men are explained by modifiable variables that suggest avenues for improvement.     

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.     

Racial and ethnic differences in receipt of primary care services between medicaid fee-for-service and managed care plans

We used a cross-sectional, population-based sample of Medicaid beneficiaries aged 18-64 to determine whether managed care enrollment was associated with reduced racial/ethnic disparities in self-reported access to primary care services compared with fee-for-service. Managed care beneficiaries reported greater access in each racial/ethnic category and for each outcome than did fee-for-service beneficiaries, although associations were not always statistically significant. Racial/ethnic minorities enrolled in managed care plans reported as much benefit from managed care enrollment as did whites. Within Medicaid, interventions aimed at the health insurance delivery model can facilitate increased access to primary care services without enhancing racial/ethnic disparities.     

Health Services Utilization by Low-Income Limited English Proficient Adults

Objectives We evaluated the health care utilization of limited English proficiency (LEP) compared to English proficient (EP) adults with the same health insurance (Medicaid managed care) and full access to professional medical interpreters. Methods Health care utilization over two years was compared for 567 LEP and 1162 EP adults. Multivariate analysis controlled for age, gender, months enrolled in Medicaid and morbidity. Results LEP compared to EP subjects were enrolled longer and more continuously in Medicaid, were 94% more likely to use primary care and 78% less likely to use the emergency department. Specialty visits and hospitalization did not differ. Conclusions When language barriers are reduced and health insurance coverage is the same, LEP patients show ambulatory health care utilization associated with lower cost and more access to preventive care through establishing a primary care home.     

Quality of diabetes care for adults with developmental disabilities

BackgroundGiven that individuals with developmental disabilities have a history of difficulty accessing appropriate health care, possess numerous risk factors for diabetes, and frequently have unique needs within the health care setting, it is important to conduct surveillance research to determine the quality of their diabetes care.Objective/HypothesisWe assessed the quality of diabetes care for adults with developmental disabilities enrolled in Kansas Medicaid. Developmental disability was defined in accordance with Kansas Medicaid program eligibility and included individuals with intellectual disability, cerebral palsy, autism, and/or seizure disorder.MethodsWe identified a retrospective cohort of persons with developmental disabilities who were also diabetic and continuously enrolled in Kansas Medicaid. We tracked their quality of care measures (Hb_A1c/glucose testing, cholesterol testing, eye examinations, microalbuminaria screening, and primary care visits) across the subsequent 12 months. Quality care measures were evaluated in relation to basic demographic variables and comorbid hypertension using unconditional logistic regression.ResultsAmong 5,960 adults with developmental disability, 666 had diabetes (11.2%). Annual testing rates were Hb_A1c/glucose testing, 51.7%; cholesterol, 44.3%; eye examinations, 29.3%; and microalbuminaria, 18.5%. Nearly all (93.5%) had contact with a primary care provider during the period. Comorbid hypertension was associated with higher rates of Hb_A1c, cholesterol testing, and primary care visits. Dual eligibility was associated with lower Hb_A1c/glucose testing and cholesterol testing rates but comparable rates for other measures. Caucasians were more likely to have had an eye examination but less likely to have had their microalbumin checked.ConclusionsAdults with developmental disabilities and diabetes who were enrolled in the Kansas Medicaid Program were screened at lower frequency than published national figures for key quality indicators of diabetes care. These results call for action to find approaches to improve their quality of care. Further work is needed to understand the barriers to appropriate care and incentives that will remedy these gaps. In addition, research is needed to determine the accuracy of diabetes identification, treatment, and monitoring of adults with developmental disabilities.     

Children's mental health services in fee-for-service Medicaid

This study analyzed annual service use and payment data for children in racial/ ethnic subgroups in Medicaid Programs of four States, and compared service use of youth treated with mental health or substance abuse (MH/SA) conditions to youth without such conditions. In addition to geographic variation in rates (6.2 to 10.7 percent used MH/SA related care), results showed children who used MH/SA services to be disproportionately older, male, and white when compared with all Medicaid children. Examination of costs per claimant found costs for the MH/SA population of children to be three to six times greater than a comparison sample.     

Peer Reviewed: Racial and Ethnic Disparities in the Quality of Diabetes Care in a Nationally Representative Sample

Introduction

Previous studies have consistently documented that racial/ethnic minority patients with diabetes receive lower quality of care, based on various measures of quality of care and care settings. However, 2 recent studies that used data from Medicare or Veterans Administration beneficiaries have shown improvements in racial/ethnic disparities in the quality of diabetes care. These inconsistencies suggest that additional investigation is needed to provide new information about the relationship between racial/ethnic minority patients and the quality of diabetes care.

Methods

We analyzed 3 years of data (2005-2007) from the Medical Expenditure Panel Survey and used multivariate models that adjusted for sociodemographic characteristics, regional location, insurance status, health behaviors, health status, and comorbidity to examine racial/ethnic disparities in the quality of diabetes care.

Results

We found that Asian patients with diabetes were less likely to have received 2 or more glycated hemoglobin (HbA1c) tests or a foot examination during the past year compared with their white counterparts. Hispanic patients with diabetes were also less likely to have received a foot examination during the past year compared with white patients with diabetes. Conversely, black patients with diabetes were more likely to have received a foot examination during the past year compared with white patients with diabetes. The differences in the quality of diabetes care remained significant even after controlling for socioeconomic status (SES), health insurance status, self-rated health status, comorbid conditions, and lifestyle behavior variables.

Conclusions

Although the link between racial/ethnic minority status and the quality of care for patients with diabetes is not completely understood, our results suggest that factors such as SES, health insurance status, self-rated health status, and other health conditions are potential antecedents of quality of diabetes care.     

Disparities in trends of hospitalization for potentially preventable chronic conditions among African Americans during the 1990s: implications and benchmarks

OBJECTIVES: We compared trends in prevalence rates of preventable cardiovascular- and diabetes-related hospitalizations between African Americans and members of other major US racial/ethnic groups. METHODS: Standardized rates for 1991 to 1998 were derived from hospital and US census data for California. RESULTS: African Americans had significantly higher hospitalization rates in 1991, and discrepancies in rates continued to widen through 1998. Overall male and female rates were approximately 3 times higher for angina, 7 times higher for hypertension, between 7 and 8 times higher for congestive heart failure, and 10 times higher for diabetes. CONCLUSIONS: Widening disparities in cardiovascular- and diabetes-related health conditions were observed in this study, possibly owing to racial inequalities in provision of effective primary care.     

Preventable hospitalization and medicaid managed care: does race matter?

This study examines the preventable hospitalization patterns of Medicaid patients by race/ethnicity to determine whether Medicaid managed care (MMC) has been more effective in some subgroups than others. It uses logistic models for three states, comparing preventable hospitalizations with marker admissions (urgent admissions, insensitive to primary care). Hospital discharge data from the Healthcare Cost and Utilization Project State Inpatient database of the Agency for Health Care Research and Quality for New York, Pennsylvania, and Wisconsin residents aged 20-64 years is used. In a more urban state, New York, MMC was effective for Whites but not for minorities. In a more rural state, Wisconsin, MMC was effective for minorities. Overall, the evidence is not strong that any particular racial group consistently benefited from MMC, or that any state consistently showed a favorable impact of MMC across racial groups. However, racial/ethnic disparity associated with the risk of preventable hospitalization is significantly lower among Medicaid patients than among private fee-for-service patients.     

Alcohol drinking patterns and medical care use in an HMO setting

The objective of this study was to examine the association of medical care use (outpatient visits and hospitalization) with alcohol drinking patterns in a large health maintenance organization (HMO). Data were gathered from a random sample of 10,292 adult respondents through a telephone survey conducted between June 1994 and February 1996. Findings indicate that current non-drinkers with no past history of drinking had higher rates of outpatient visits and hospitalizations than current drinkers. Among current drinkers, medical care use declined slightly as drinking levels increased. Among nondrinkers, those with a drinking history exhibited significantly higher use of outpatient visits and hospital care than nondrinkers with no drinking history and current drinkers. Controlling for demographic and socioeconomic factors, health status, and common medical conditions in multivariate analyses suggests that nondrinkers with a drinking history use more services because they are sicker than other nondrinkers or current drinkers.     

The complementarity and substitution between unconventional and mainstream medicine among racial and ethnic groups in the United States

OBJECTIVES: To describe racial and ethnic differences in the utilization patterns of 12 common types of complementary and alternative medicine (CAM) and mainstream medicine (MSM) and to test whether a specific CAM type is a substitute for or a complement to MSM among five racial and ethnic groups in the United States. METHODS: The Medical Expenditure Panel Survey in 1996 and 1998 were used. The sample of 46,673 respondents was stratified into non-Hispanic whites (NHW), Hispanics, blacks, Asians, and other races. Twelve types of CAM visits and visits to office-based and outpatient physicians were used to describe the pattern of CAM and MSM use. Utilization patterns among each racial and ethnic group were established and compared. Multivariate analyses were conducted to test whether each type of CAM and MSM were complements or substitutes within a racial and ethnic group, controlling for respondents' sociodemographics and health. RESULTS: Significant intergroup differences in the prevalence rates of using various types of CAM were found. In particular, for some racial and ethnic groups, CAM can be either a substitute for or a complement to MSM visits, depending on the CAM type. More complementary relationships between CAM and physician visits were found in NHW and Asians than in other groups. All significant relationships between CAM types and physician visits among Hispanics and other races (predominantly Native American Indians) were substitution. CONCLUSIONS: Complementarity and substitution of CAM and MSM varied by racial and ethnic groups and by type of CAM. Culturally sensitive approaches are needed in successful integration of CAM in treatment management.     

Hypertension, diabetes, hypercholesterolemia, and their combinations increased health care utilization and decreased health status

BACKGROUND AND OBJECTIVE: For individuals with hypertension, diabetes, or hypercholesterolemia, the relative magnitude of cardiovascular risk factors and the effect of multiple risk factors remains controversial and both treatment practices and health care usage vary. We sought to determine the effect of hypertension, diabetes, hypercholesterolemia, and their combinations on health care utilization and health status through analysis of data from a large national survey. METHODS: We applied the Anderson model to a cross-sectional representative sample (n=15,107) of the U.S. civilian, noninstitutionalized population (the 1996 Medical Expenditure Panel Survey). RESULTS: For diabetes, additional risk factors did not increase the likelihood of emergency room (ER) visits or hospitalizations but were associated with increased outpatient visits and poorer health status. For hypertension, additional risk factors increased the likelihood of hospitalization (but not ER visits), the number of outpatient visits, and poorer health status. For hypercholesterolemia, additional risk factors were associated with increased likelihood of ER visits, hospitalizations, and poorer health status but not more outpatient visits. Diabetes had the largest effect on health care utilization and health status. CONCLUSION: These findings re-emphasize the magnitude of diabetes as a major risk factor associated with increased ER visits, hospitalizations, outpatients visits, and lower health status.
