What patients and their relatives think about testing for BMPR2.

Clinical genetic testing is available for mutations in BMPR2 associated with pulmonary arterial hypertension (PAH). The aim of this study is to assess attitudes of individuals affected by or at risk for PAH regarding genetic testing. Structured telephone interviews were conducted with 119 individuals affected by or at risk for PAH recruited from pulmonary hypertension clinic at Vanderbilt, Vanderbilt familial PAH registry, attendees at 2006 PHA meeting, and a local PAH support group. Sixty-four percent reported knowing little or nothing about BMPR2 testing. Predictors of greater self-assessed knowledge included having an affected family member and learning about BMPR2 testing through the internet. Most respondents reported that while they spent some time thinking about being tested for BMPR2, they had little trouble deciding. The most frequently cited reason for testing was to provide information for their children. About 20% said they had been tested, even though <5% have actually received clinical testing. Although patients with PAH and their at-risk relatives typically feel relatively uninformed about testing for mutations in BMPR2 and at times are confused about their testing status, they nonetheless report that it is easy to decide about testing.

Racial and gender differences in utilization of Medicaid substance abuse services among adolescents.

OBJECTIVE: This study examined race and gender disparities in utilization of substance abuse treatment among adolescents enrolled in Medicaid in Tennessee. METHODS: By using Medicaid enrollment, encounter, and claims data, utilization of substance abuse services for the population of adolescents enrolled in TennCare was examined in two ways. The first utilization measure considered annual utilization rates and probability of use of substance abuse services for the statewide population of enrolled adolescents (approximately 170,000 per year). The second examined the age at which the first substance abuse service was received for the 8,473 youths who had that service paid for by TennCare during state fiscal years 1997 to 2001. RESULTS: Proportionally, among adolescents, more whites than blacks and more males than females used substance abuse services. The disparities were greater than differences in prevalence rates explain. Black females had the greatest disparity in service utilization. Whites and females received their first substance abuse service at a younger age than blacks or males in this Medicaid population. However, the age difference may not be clinically significant. CONCLUSIONS: The low utilization rates, in general, and the disparities in service use by race and gender raise questions about the identification of substance use problems at both provider and system levels.

Access and service use by children with autism spectrum disorders in Medicaid Managed Care.

Although Medicaid is the largest public payer of behavioral health services, information on access and utilization of services is lacking, and no data on the frequency of service use or types of services provided for children with autism spectrum disorders (ASDs) are available. As states move toward managed care approaches for their Medicaid program, services information is critical. Behavioral health service data for children with autism spectrum disorders were collected from a state Medicaid Managed Care (MMC) program and analyzed from fiscal years 1995 through 2000. Findings revealed that the number of children who received services over time increased significantly; however, the rate of service use was only one tenth of what should be expected based on prevalence rates. The mean number of service days provided per child decreased significantly, about 40%, and the most prevalent forms of treatment changed. Day treatment vanished and medication and case management increased disproportionately to the number of children served. Explanations and implications of the findings are presented as well as recommendations for future research.

Effects of managed care on southern youths' behavioral services use.

Children and adolescents' access to Medicaid-financed behavioral health services was examined over 8 years in Tennessee (managed care) and Mississippi (fee-for-service [FFS]) using logistic regression. Managed care reduced access to behavioral care overall, overnight services (e.g., inpatient), and specialty outpatient services. Managed care also restricted the relative use of overnight and specialty outpatient for children and adolescents. However, managed care had pronounced effects on use of case management services. We also document differences in access and mix of behavioral services used over time by race, sex, age, and Medicaid enrollment category.

Access to and patterns of use of behavioral health services among children and adolescents in TennCare.

OBJECTIVE: This study assessed trends in access to and use of behavioral health services for school-aged children in TennCare, Tennessee's Medicaid managed care program, between state fiscal years 1995 and 2000. METHODS: Claims, encounter, and enrollment data from the Bureau of TennCare were used. The data analyzed were restricted to services and enrollment periods for children and adolescents between the ages of four and 17 years at the time of service or enrollment. Measures were calculated in four areas: overall access to behavioral health services, use of inpatient services, use of outpatient specialty treatment services, and use of supportive services like case management and medication management. RESULTS: The number of youths who received a behavioral service increased by nearly 50 percent between state fiscal years 1995 and 2000. At the same time, the number of youths enrolled in TennCare increased by 19 percent. The annual access rate increased from 72.7 youths per 1000 enrollees to 91.7. However, the volume of services for children fell. Access rates were low relative to estimates of need in this population. The system made less use of inpatient services and relied more on outpatient services, particularly case management and medication management services. CONCLUSIONS: Children's access rates for behavioral health services improved even as the TennCare program expanded to cover more children. The system served more youths in part by reducing the volume of services for children receiving treatment and substituting more supportive services. Ongoing performance monitoring for policy making will require enhancements of data monitoring activities by the state.

Medicare beneficiaries more likely to receive appropriate ambulatory services in HMOs than in traditional medicare.

With quality-of-care bonus payments now available for Medicare Advantage health maintenance organizations (HMOs) and for accountable care organizations in traditional Medicare, the need to understand the relative quality of care delivered to Medicare enrollees has increased. We compared the quality of ambulatory care from 2003 through 2009 between beneficiaries enrolled in Medicare Advantage HMOs and those enrolled in traditional Medicare, and we assessed how the performance of various types of Medicare HMOs differed from that of traditional Medicare for these same measures. We found that beneficiaries in Medicare HMOs were consistently more likely than those in traditional Medicare to receive appropriate breast cancer screening, diabetes care, and cholesterol testing for cardiovascular disease. We also found that Medicare HMO physicians were rated less favorably by their patients than were physicians in traditional Medicare in 2003; however, by 2009 the opposite was true. Not-for-profit, larger, and older Medicare HMOs performed consistently more favorably on clinical measures and ratings of care than for-profit, smaller, and newer HMOs. Our results suggest that the positive effects of more-integrated delivery systems on the quality of ambulatory care in Medicare HMOs may outweigh the potential incentives to restrict care under capitated payments.

Analysis Of Medicare Advantage HMOs compared with traditional Medicare shows lower use of many services during 2003-09.

Enrollment in Medicare Advantage, the managed care program for Medicare beneficiaries, has grown rapidly, from 4.6 million enrollees in 2003 to 12.8 million by 2012, or 27 percent of all current Medicare beneficiaries. We analyzed utilization patterns of enrollees in Medicare Advantage health maintenance organization (HMO) plans compared to matched samples of people in traditional Medicare during 2003-09, to ascertain whether the HMO enrollees demonstrated different levels of use of services, which can be a hallmark of more integrated care. We found that utilization rates in some major categories, including emergency departments and ambulatory surgery or procedures, generally were 20-30 percent lower in Medicare Advantage HMOs in all years. Medicare Advantage HMO enrollees initially had lower rates of ambulatory visits and hospitalizations, although these rates converged by 2008; they also received about 10 percent fewer hip or knee replacements. In contrast, HMO enrollees underwent more coronary bypass surgery than patients in traditional Medicare. These findings suggest that overall, Medicare Advantage HMO enrollees might use fewer services and be experiencing more appropriate use of services than enrollees in traditional Medicare.

Patient-centered medical homes in the United States.

The concept of a medical home is receiving increased attention as a potential means to improve care and reduce costs. This study describes the characteristics and capabilities of practices that have achieved recognition of National Committee for Quality Assurance as a "patient-centered medical home" (PCMH). Both small and large practices demonstrate capabilities related to the goals of PCMH of accessible, coordinated, and patient-centered care; however, practices affiliated with larger organizations achieve higher levels of PCMH recognition compared with unaffiliated small practices. Efforts to support practices to implement medical home capabilities are needed, particularly in the use of data for population management and patient self-management.

Classification of health plans based on relative resource use and quality of care.

OBJECTIVE: To examine variation among commercial health plans in resource use and quality of care for patients with diabetes mellitus or cardiovascular disease. STUDY DESIGN: Cohort study using Healthcare Effectiveness Data and Information Set data submitted to the National Committee for Quality Assurance in 2008. METHODS: Composite measures were estimated for diabetes and cardiovascular disease resource use and quality of care. A "value" classification approach was defined. Obtained were descriptive statistics, Pearson product moment correlations between resource use and quality of care, and 90% confidence intervals around each health plan's composite measures of resource use and quality of care. Health plans were classified based on their results. RESULTS: For patients with diabetes, the correlation between combined medical care services resource use and composite quality of care is negative (-0.201, p = .008); the correlation between ambulatory pharmacy services resource use and composite quality of care is positive (0.162, p = .03). For patients with cardiovascular disease, no significant correlation was found between combined medical care services resource use and composite quality of care (-0.007, p = .94) or ambulatory pharmacy services resource use (0.170, p = .06). CONCLUSIONS: Measures of resource use and quality of care provide important information about the value of a health plan. Although our analysis did not determine causality, the statistically weak or absent correlations between resource use and quality of care suggest that health plans and practices can create higher value by improving quality of care without large increases in resource use or by maintaining the same quality of care with decreased resource use.

The ecology of adolescent substance abuse service utilization.

This paper presents an ecological-community model toward the explanation of variation in patterns of substance abuse (SA) service utilization among adolescents who are enrolled in Tennessee's Medicaid program (TennCare). Guided by a theoretical framework that draws from the social ecology work of Bronfenbrenner and health services utilization models promoted by Aday and Andersen, we apply a social indicators approach toward explaining the impact of community ecology on identification of SA and treatment engagement. Both county-level rates and individual-level treatment utilization are examined and hierarchical linear modeling is incorporated to examine the individual-in-community phenomenon. This study is an expansion of previous service utilization research and suggests that explanations of youth's service utilization must necessarily include not only individual, familial, and service system characteristics, but community factors, as well.

Physical and behavioral health of Medicaid children in two southern states.

OBJECTIVES: As the primary insurer of children in the United States, Medicaid covers at least one in four US children. Information on the health and behavioral health needs of this group of children is critical to plan, deliver, and monitor services accordingly. METHODS: Parent interview data from a representative sample of Medicaid children in two Southern states were used to generate information from standardized questionnaires on physical health status, chronic illnesses, physical functioning, emotional and behavioral symptoms, and psychosocial functioning. RESULTS: The levels of physical and behavioral health and co-occurring problems were higher than other estimates available on the general population. CONCLUSIONS: The high levels of health problems among Medicaid-enrolled children need attention in the current struggles over Medicaid reform. Support for improving screening, referral, and integration of services is discussed, as well as the importance of monitoring service system performance in this era of managed care.
