Medicaid Managed Care and Health Care Access for Adult Beneficiaries with Disabilities

Objective. To evaluate the impact of Medicaid managed care organizations (MCO) on health care access for adults with disabilities (AWDs).
Data Sources. Mandatory and voluntary enrollment data for AWDs in Medicaid MCOs in each county were merged with the Medical Expenditure Panel Survey and the Area Resource File for 1996–2004.
Study Design. I use logit regression and two evaluation perspectives to compare access and preventive care for AWDs in Medicaid MCOs with FFS. From the state's perspective, I compare AWDs in counties with mandatory, voluntary, and no MCOs. From the enrollee's perspective, I compare AWDs who must enroll in an MCO or FFS to those who may choose between them.
Principal Findings. Mandatory MCO enrollees are 24.9 percent more likely to wait >30 minutes to see a provider, 32 percent more likely to report a problem accessing a specialist, and 10 percent less likely to receive a flu shot within the past year. These differences persist from the state evaluation perspective.
Conclusions. States should not expect a dramatic change in health care access when they implement Medicaid MCOs to deliver care to the adult disabled population. However, continued attention to specialty care access is warranted for mandatory MCO enrollees.     

Does the quality of care in Medicaid MCOs vary with the form of physician compensation?

A growing fraction of Medicaid participants are enrolled in managed care organizations (MCOs). MCOs contract with primary care physicians (PCPs) to provide health-care services to Medicaid enrollees. The PCPs are generally compensated either via fee-for-service (FFS) or via capitated arrangements. This paper investigates whether the quality of care that Medicaid enrollees receive varies with the means by which PCPs are compensated. Using data for all Medicaid MCO enrollees in a large state, we find that enrollees in MCOs that pay their PCPs exclusively via FFS arrangements are more likely to receive services for which the PCPs receive additional compensation. These enrollees also are less likely to receive services for which the PCPs do not receive additional compensation. These findings suggest that financial incentives may influence the behavior of PCPs in Medicaid MCOs, and thus the quality of the health care received by Medicaid participants enrolled in MCOs.     

Utilization, costs, and access to primary care in fee-for-service and managed care plans

This study compares access to primary care, utilization, and costs among enrollees in four forms of managed care and an indemnity plan. We use 1996 data from a commercial insurer. Most managed care enrollees had better access to primary care services than indemnity enrollees. This access was associated with a generally lower rate of preventable hospitalization. Per capita inpatient costs were notably lower in managed care plans than in the indemnity plan. We describe how health care managers can use readily available administrative data and straightforward statistical techniques to enhance routine monitoring for quality and costs. Policy makers can use this approach to identify health services trends, and to evaluate access to health services for individuals enrolled in various benefit plan types.     

Plan characteristics and SSI enrollees' access to and quality of care in four TennCare MCOs

OBJECTIVE: To assess hypotheses about which managed care organization (MCO) characteristics affect access to care and quality of care--including access to specialists, providers' knowledge about disability, and coordination of care--for people with disabilities. DATA SOURCES/STUDY SETTING: Survey of blind/disabled Supplemental Security Income (SSI) enrollees in four MCOs serving TennCare, Tennessee's Medicaid managed care program, in Memphis, conducted from 1998 through spring 1999. STUDY DESIGN: We compared enrollee reports of access and quality across the four MCOs using regression methods, and we use case study methods to assess whether patterns both within and across MCOs are consistent with the hypotheses. DATA COLLECTION: We conducted computer-assisted telephone surveys and used regression analysis to compare access and quality controlling for enrollee characteristics. PRINCIPAL FINDINGS: Although the four MCOs' characteristics varied, access to providers, coordination of care, and access to some services were generally similar across MCOs. Enrollees in one plan, the only MCO with a larger provider network and that paid physicians on a fee-for-service basis, reported their providers were more knowledgeable, and they had more secondary preventive care visits. Differences found in access to specialists and delays in approving care appear to be unrelated to characteristics reported by the MCOs, but instead may be related to how tightly utilization is reviewed. CONCLUSIONS: Plan networks, financial incentives, utilization management methods, and state requirements are important areas for further study, and, in the meantime, ongoing monitoring of SSI enrollees in each MCO may be important for detecting problems and successes.     

Managed Care Organizational Characteristics and Health Care Use among Children with Special Health Care Needs

Objective. To examine the relationship between features of managed care organizations (MCOs) and health care use patterns by children.
Data Sources. Telephone survey data from 2,223 parents of children with special health care needs, MCO-administrator interview data, and health care claims data.
Study Design. Cross-sectional survey data from families about the number of consequences of their children's conditions and from MCO administrators about their plans' organizational features were used. Indices reflecting the MCO characteristics were developed using data reduction techniques. Hierarchical models were developed to examine the relationship between child sociodemographic and health characteristics and the MCO indices labeled: Pediatrician Focused (PF) Index, Specialist Focused (SF) Index, and Fee-for-Service (FFS) Index, and outpatient use rates and charges, inpatient admissions, emergency room (ER) visits, and specialty consultations.
Data Collection/Extraction Methods. The telephone and MCO-administrator survey data were linked to the enrollment and claims files.
Principal Findings. The child's age, gender, and condition consequences were consistent predictor variables related to health care use and charges. The PF Index was associated with decreased outpatient use rates and charges and decreased inpatient admissions. The SF Index was associated with increased ER visits and decreased specialty consultations, while the FFS Index was associated with increased outpatient use rates and charges.
Conclusion. After controlling for sociodemographic and health characteristics, the PF, SF, and FFS indices were significantly associated with children's health care use patterns.     

Health plan quality-of-care information is undermined by voluntary reporting

BACKGROUND: Most health services in the United States are delivered by managed care organizations (MCOs). Publicly available, plan-specific performance information is required to adequately assess healthcare quality provided. Using women's health indicators, we compared performance results for MCOs and evaluated whether those MCOs that publicly report quality-of-care (QOC) results demonstrate better QOC than those plans that restrict public access to data. METHODS: Data from the Health Plan Employer Data and Information Set (HEDIS) for commercial MCOs in 1998 were analyzed for women's QOC indicators. Plan-specific, regional, and national performances were analyzed and results compared to established benchmarks. Public-reporting plans were compared to plans that restrict access to QOC information. Linear regression was used to identify determinants of health plan performance including public release of information. RESULTS: Commercial MCOs had wide variations in QOC indicators and, on average, failed to attain national health goals for most women's health indicators analyzed. Plans that restricted public access to QOC information had poorer performance than those that did not (p<0.05). Results suggest that whether a plan publicly releases its performance information is highly associated with health plan performance even after taking into account other factors. CONCLUSIONS: The voluntary aspect of reporting and the ability of health plans to restrict public access is allowing poorer performing health plans to escape public scrutiny. Variations in QOC have clinical significance and, if publicly available, would enable individuals to select high-quality healthcare products. The ability of health plans to restrict public information is not consistent with the 1973 Health Maintenance Organization Act requiring public information on health plan quality. A national strategy to ensure that QOC information is available on all healthcare systems is past due.     

Managed Care, School Health Programs, and Adolescent Health Services: Opportunities for Health Promotion

ABSTRACT: The rapid expansion of managed care creates opportunities and dilemmas for those involved in school health and adolescent health promotion. Managed care organizations (MCOs), public health agencies, and school and adolescent health providers share certain common goals and priorities including an emphasis on prevention, cost-effectiveness, and quality of care — and a willingness to explore innovative approaches to health promotion and disease prevention. However, MCOs often face conflicting challenges, balancing the goals of cost containment and investment in prevention. In considering support for school health programs, MCOs will be interested in evidence about the effectiveness of services in improving health and/or reducing medical expenditures. Mechanisms for improving prevention efforts within MCOs include quality assurance systems to monitor the performance of health plans, practice guidelines from professional organizations, and the contracting process between payers and health care providers. Development of partnerships between MCOs and schools will be a challenge given competing priorities, variation in managed care arrangements, structural differences between MCOs and schools, and variability in services provided by school health programs     

Variability in Asthma Care and Services for Low-Income Populations among Practice Sites in Managed Medicaid Systems

Objective. To characterize and describe variability in processes of asthma care and services tailored for low–income populations in practice sites participating in Medicaid managed care (MMC).
Study Setting. Eighty-five practice sites affiliated with five not-for-profit organizations participating in managed Medicaid (three group-model health maintenance organizations [HMOs] and two Medicaid managed care organizations [MCOs]).
Study Design/Data Collection. We conducted a mail survey of managed care practice site informants using a conceptual model that included chronic illness care and services targeting low-income populations. The survey asked how frequently a number of processes related to asthma care occurred at the practice sites (on a scale from "never" to "always"). We report mean and standard deviations of item scores and rankings relative to other items. We used within-MCO intraclass correlations to assess how consistent responses were among practice sites in the same MCO.
Principal Findings. Processes of care related to asthma varied greatly in how often practice sites reported doing them, with information systems and self-management support services ranking lowest. There was also significant variation in the availability of services targeting low-income populations, specifically relating to cultural diversity, communication, and enrollee empowerment. Very little of the site-to-site variation was attributable to the MCO.
Conclusions. Our conceptual framework provides a means of assessing the provision of chronic illness care for vulnerable populations. There is room for improvement in provision of chronic asthma care for children in managed Medicaid, particularly in the areas of self-management support and information systems. The lack of consistency within MCOs on many processes of care suggests that care may be driven more at the practice site level than the MCO level, which has implications for quality improvement efforts.     

Preventable hospitalizations: a tool for planning and marketing ambulatory health care services

As the health care system evolves towards increased levels of managed care, planners and managers will need to understand how the utilization of ambulatory care services influences the use of more expensive hospital care. Preventable hospitalization, an index based on Ambulatory Care Sensitive (ACS) conditions, is proposed as an indicator for identifying communities with significant ambulatory care needs. The design and marketing of ambulatory health care services functionally adapted to meet the challenges of managed care will require new forms of health care information to plan, market, monitor, and evaluate the outcomes of health care policies and programs. An example is presented of the use of preventable hospitalizations as indicators of ambulatory care needs in 48 communities in Massachusetts.     

Barriers and Facilitators to Providing Common Preventive Screening Services in Managed Care Settings

Despite increasing emphasis on disease prevention and health promotion, and ample evidence demonstrating the effectiveness of preventive services, such services are underutilized in the United States. The current trend of health care toward health maintenance organizations and other managed care systems opens the door, perhaps to more effective control of heart disease, cancers and other chronic diseases through preventive care. This warrants attention to the barriers/facilitators to the provision/utilization of preventive screening services in such settings. Overall goal of this study was to assess barriers/facilitators to the provision/utilization of preventive services in managed care organizations (MCOs). This was accomplished by a) identifying barriers/facilitators to the provision/utilization of three common preventive screening services (cholesterol screenings, mammograms, and Pap smears); and b) profiling typical MCO recipients of these three preventive screening services. A self-administered, mail questionnaire was used to obtain information from a national sample of 1,200 Directors of MCOs associated with preventive care. A total of 175 usable responses were received resulting in a 17.3 percent net response rate. The strongest barrier to the provision of all three screening services is the inability of them to generate short term savings for the MCO. Other barriers include high disenrollment rates, conflicting recommendations about effectiveness (for mammograms and cholesterol screenings), and patients' fears of getting a positive result (for mammograms and Pap smears). The improved health status as a result of early intervention, high consumer awareness (for mammograms and Pap smears), and long term savings are important facilitators to the provision/utilization of these screening services. Comparing barriers and facilitators across the three services shows the stronger barriers affecting the provision/utilization of mammograms. For all three screening services, typical managed care recipients are those in the high income groups with greater education levels. However, with the increasing enrollment of Medicaid beneficiaries into managed care, MCOs may find themselves selectively targeting these high risk low income and less educated individuals to receive the preventive screening services. Study findings should be useful to health planners, policymakers and researchers at all levels in their efforts to encourage and promote healthier lifestyle choices among U.S. residents. Future studies should address receipt of preventive services by Medicaid and Medicare beneficiaries in managed care settings.     

Managed care and preventable hospitalization among Medicaid adults

OBJECTIVE: The study examines the association between managed care enrollment and preventable hospitalization patterns of adult Medicaid enrollees hospitalized in four states. DATA SOURCES/STUDY SETTING: Hospital discharge data from the Healthcare Cost and Utilization Project (HCUP) database of the Agency for Healthcare Research and Quality (AHRQ) for New York (NY), Pennsylvania (PA), Wisconsin (WI), and Tennessee (TN) residents in the age group 20-64 hospitalized in those states, linked to the Area Resource File (ARF) and American Hospital Association (AHA) survey files for 1997. STUDY DESIGN: The study uses separate logistic models for each state comparing preventable admissions with marker admissions (urgent, insensitive to primary care). The model controls for socioeconomic and demographic variables, and severity of illness. PRINCIPAL FINDINGS: Consistently in different states, private health maintenance organization (HMO) enrollment was associated with fewer preventable admissions than marker admissions, compared to private fee-for-service (FFS). However, Medicaid managed care enrollment was not associated with a reduction in preventable admissions, compared to Medicaid FFS. CONCLUSIONS: Our analysis suggests that the preventable hospitalization pattern for private HMO enrollees differs significantly from that for commercial FFS enrollees. However, little difference is found between Medicaid HMO enrollees and Medicaid FFS patients. The findings did not vary by the level of Medicaid managed care penetration in the study states.     

How does managed care manage the frail elderly? The case of hospital readmissions in fee-for-service versus HMO systems

OBJECTIVES: This study examined whether hospital readmissions varied among the frail elderly in managed care versus fee-for-service (FFS) systems. SETTING AND PARTICIPANTS: Random sample of 450 patients, aged 65 and over, from a large vertically integrated health care system in San Diego, California. Participants were receiving physician-authorized home health and survived and 18-month follow-up period. MAIN OUTCOME MEASURES: Multiple logistic regression analyses were used to conduct comparisons of readmissions and preventable readmissions by plan type. Two methods to identify preventable readmissions were developed, one based on a computerized algorithm of service use patterns, and another based on blind clinical review. RESULTS: The odds of having a preventable hospital readmission within 90 days of an index admission were 3.51 (P = 0.06) to 5.82 (P = 0.02) times as high for Medicare HMO enrollees compared to Medicare FFS participants, depending on the method used to assess preventability. Readmission patterns were similar for Medicare HMO enrollees and FFS study participants dually enrolled in Medicare and Medicaid. CONCLUSION: In this group of frail elderly Medicare beneficiaries, those enrolled in an HMO were more likely to have a preventable hospital readmission than those receiving care under FFS. These results suggest that policies promoting stringent approaches to utilization control (e.g., early hospital discharge, reduced levels of post-acute care, and restricted use of home health services) may be problematic for the frail elderly.     

Satisfaction with health care of dually eligible older beneficiaries

Satisfaction with health care was compared for dually eligible older beneficiaries receiving care in three settings: a managed care organization (MCO) that is at risk for providing Medicare and Medicaid benefits (n = 200); the fee-for-service (FFS) sector in the same ZIP Code (n = 201); and respondents to the national Medicare Current Beneficiary Survey (MCBS) (n = 531). Patients in the MCO were more likely to be highly satisfied in three domains--global quality, access to care, and technical skills--compared with patients in the local and national FFS study groups but fewer were highly satisfied with the interpersonal manner of their providers.     

Improving the health of infants on Medicaid by collocating special supplemental nutrition clinics with managed care provider sites

OBJECTIVES: This study tested whether collocation of Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) clinics at managed care provider sites improved health care for infants enrolled in Medicaid and WIC. METHODS: Weights and immunization rates were studied for the 1997 birth cohort of African American infants enrolled in WIC and Medicaid in Detroit, Mich. Infants using traditional WIC clinics and health services were compared with those enrolled under Medicaid in 2 managed care organizations (MCOs), of whom about half obtained WIC services at MCO provider sites. RESULTS: Compared with other infants, those who used collocated WIC sites either were closer to their age-appropriate weight or had higher immunization rates when recertified by WIC after their first birthday. Specific benefits (weight gain or immunizations) varied according to the priorities at the collocated sites operated by the 2 MCOs. CONCLUSIONS: Collocation of WIC clinics at MCO sites can improve health care of low-income infants. However specific procedures for cooperation between WIC staff and other MCO staff are required to achieve this benefit.     

Use of preventive services by managed care enrollees: an updated perspective

We examined whether enrollees in managed care plans received more preventive services than enrollees in non-managed care plans did, by conducting an updated literature synthesis of studies published between 1990 and 1998. We found that 37 percent of comparisons indicated that managed care enrollees were significantly more likely to obtain preventive services; 3 percent indicated that they were significantly less likely to do so; and 60 percent found no difference. Enrollees in group/staff-model health maintenance organizations (HMOs) were more likely to receive preventive services, but there was little evidence, outside of Medicaid managed care, that managed care plans are worse at providing preventive services. However, most of the evidence is equivocal: Provision of preventive services was neither better nor worse in managed versus non-managed care plans. Because of the blurred distinctions among types of health plans, more research is needed to identify which plan characteristics are most likely to encourage appropriate utilization.     

Medicaid prenatal care: a comparison of use and outcomes in fee-for-service and managed care.

BACKGROUND. To control rising costs, state Medicaid agencies are enrolling recipients in managed care health plans (MCPs). We performed this study to assess this policy's impact on accessibility and outcomes of Medicaid-funded prenatal care. METHODS. We performed a retrospective, controlled study with three cohorts: a study group of 1106 Medicaid recipients enrolled in three MCPs, a matched comparison group of 4830 recipients receiving care in the fee-for-service (FFS) system, and a second matched comparison group of 4434 non-Medicaid enrollees of the same MCPs. Data on prenatal care use and birth outcomes were obtained through linkage of claims and discharge files with birth certificate files. RESULTS. Medicaid recipients enrolled in MCPs used prenatal care similarly to those in the FFS system and showed equal or modestly improved birth-weight distributions. However, Medicaid MCP enrollees showed poorer use of prenatal care and birth outcomes compared with non-Medicaid enrollees of the same plans. CONCLUSIONS. Enrollment in MCPs has a neutral or small beneficial effect on the prenatal care received by the Medicaid population. However, providing financial access and modifying the system of care for this population did not result in parity with the general population.     

What are Medicare managed care plans doing to measure and improve quality of care?

To explore managed care plans' efforts to assess and improve quality of care for Medicare beneficiaries, the authors surveyed managed care plans with risk contracts for Medicare beneficiaries in 20 large metropolitan areas in January 1998. The survey inquired about: (1) the health plans' efforts to assess and improve quality of care for specific underuse, overuse, and misuse problems; (2) how the health plans assessed functional status of enrollees, and (3) the quality improvement program they believed had the greatest impact on the health of enrollees. The managed care plans reported a heterogeneous mix of quality improvement activities ranging from poorly developed to very sophisticated. The vast majority of the more sophisticated programs addressed problems with underuse of services rather than overuse or misuse.     

Access and use of health services by chronically mentally ill Medicaid beneficiaries

This article has two objectives: to quantify the access and utilization of services received by chronically mentally ill Medicaid recipients, and to compare service utilization and access under prepayment and fee-for-service (FFS) payment. The study setting is Hennepin County (Minneapolis), Minnesota, where 35 percent of Medicaid recipients were randomly assigned to receive services from prepaid plans. An algorithm was developed to identify recipients with chronic mental illness, resulting in 739 study participants, split approximately evenly between prepayment and FFS Medicaid. Data were collected through in-person surveys at baseline, and after 1 year. We found slight improvements in the majority of access measures studied and no significant decreases in the use of inpatient or outpatient services for enrollees in prepaid health plans. The results support efforts to expand the use of prepaid health plans to meet the needs of non-institutionalized chronically mentally ill Medicaid beneficiaries.     

Managed Care Organizations and Public Health: Exploring Collaboration on Adolescent Immunizations

ABSTRACT: Managed care organizations (MCOs) joined local and state public health agencies in a pilot effort to improve hepatitis B immunization rates of adolescents in an urban and a suburban/rural school district. The pilot also explored issues inherent in public and private collaboration on population health improvement.
Local public health agencies provided links to schools in their communities, took the lead in implementing school-based immunization programs, and provided health education materials. MCOs contributed financial support necessary for the project. The final cost per fully vaccinated student, not taking into account the work group's planning and coordination time, was little more than the catalog price of the vaccine alone.
Managed care organizations face challenges that complicate their participation and funding of school-based vaccinations: 1) Limited data on health plans of participating students complicate allocation of costs to each MCO; 2) Double-paying occurs for MCOs paying clinics a monthly, per-member rate that already includes adolescent immunizations; 3) When schools provide adolescent immunizations, MCOs lose the "hook" that draws adolescents to clinics for comprehensive health services.
When self-consenting is permitted, schools can achieve a high consent and completion rates for multi-dose adolescent immunizations such as hepatitis B. At the same time, MCOs have the responsibility to provide members with comprehensive care and should continue to examine both internal modifications and external partnerships as opportunities to improve their services to adolescents.
