Did Medicaid expansion close African American-white health care disparities nationwide? A scoping review.

OBJECTIVES: To investigate the impact of the Affordable Care Act's (ACA) Medicaid expansion on African American-white disparities in health coverage, access to healthcare, receipt of treatment, and health outcomes. DESIGN: A search of research reports, following the PRISMA-ScR guidelines, identified twenty-six national studies investigating changes in health care disparities between African American and white non-disabled, non-elderly adults before and after ACA Medicaid expansion, comparing states that did and did not expand Medicaid. Analysis examined research design and findings. RESULTS: Whether Medicaid eligibility expansion reduced African American-white health coverage disparities remains an open question: Absolute disparities in coverage appear to have declined in expansion states, although exceptions have been reported. African American disparities in health access, treatment, or health outcomes showed little evidence of change for the general population. CONCLUSIONS: Future research addressing key weaknesses in existing research may help to uncover sources of continuing disparities and clarify the impact of future Medicaid expansion on African American health care disparities.

Increased Mental Health Treatment Financing, Community-Based Organization's Treatment Programs, and Latino-White Children's Financing Disparities.

BACKGROUND: Latino child populations are large and growing, and they present considerable unmet need for mental health treatment. Poverty, lack of health insurance, limited English proficiency, stigma, undocumented status, and inhospitable programming are among many factors that contribute to Latino-White mental health treatment disparities. Lower treatment expenditures serve as an important marker of Latino children's low rates of mental health treatment and limited participation once enrolled in services. AIMS: We investigated whether total Latino-White expenditure disparities declined when autonomous, county-level mental health plans receive funds free of customary cost-sharing charges, especially when they capitalized on cultural and language-sensitive mental health treatment programs as vehicles to receive and spend treatment funds. Using Whites as benchmark, we considered expenditure pattern disparities favoring Whites over Latinos and, in a smaller number of counties, Latinos over Whites. METHODS: Using segmented regression for interrupted time series on county level treatment systems observed over 64 quarters, we analyzed Medi-Cal paid claims for per-user total expenditures for mental health services delivered to children and youth (under 18 years of age) during a study period covering July 1, 1991 through June 30, 2007. Settlement-mandated Medicaid's Early Periodic Screening, Diagnosis and Treatment (EPSDT) expenditure increases began in the third quarter of 1995. Terms were introduced to assess immediate and long term inequality reduction as well as the role of culture and language-sensitive community-based programs. RESULTS: Settlement-mandated increased EPSDT treatment funding was associated with more spending on Whites relative to Latinos unless plans arranged for cultural and language-sensitive mental health treatment programs. However, having programs served more to prevent expenditure disparities from growing than to reduce disparities. DISCUSSION: EPSDT expanded funding increased proportional expenditures for Whites absent cultural and language-sensitive treatment programs. The programs moderate, but do not overcome, entrenched expenditure disparities. These findings use investment in mental health services for Latino populations to indicate treatment access and utilization, but do not explicitly reflect penetration rates or intensity of services for consumers. IMPLICATIONS FOR POLICY: New funding, along with an expectation that Latino children's well documented mental health treatment disparities will be addressed, holds potential for improved mental health access and reducing utilization inequities for this population, especially when specialized, culturally and linguistically sensitive mental health treatment programs are present to serve as recipients of funding. IMPLICATIONS FOR RESEARCH: To further expand knowledge of how federal or state funding for community based mental health services for low income populations can drive down the longstanding and considerable Latino-White mental health treatment disparities, we must develop and test questions targeting policy drivers which can channel funding to programs and organizations aimed at delivering linguistically and culturally sensitive services to Latino children and their families.

Increased Medicaid Financing and Equalization of African Americans' and Whites' Outpatient and Emergency Treatment Expenditures.

OBJECTIVE: We investigated whether a new funding opportunity to finance mental health treatment, provided to autonomous county-level mental health systems without customary cost sharing requirements, equalized African American and White children's outpatient and emergency treatment expenditure inequalities. Using Whites as a benchmark, we considered expenditure patterns favoring Whites over African Americans ("disparities") and favoring African Americans over Whites ("reverse disparities"). METHODS: Settlement-mandated Early Periodic Screening Diagnosis and Treatment (EPSDT) expenditure increases began in the third quarter of 1995. We analyzed Medi-Cal paid claims for mental health services delivered to youth (under 18 years of age) over 64 quarters for a study period covering July 1, 1991 through June 30, 2007 in controlled cross-sectional (systems), longitudinal (quarters) analyses. RESULTS: Settlement-mandated increases in EPSDT treatment funding was associated with relatively greater African American vs. White expenditures for outpatient care when systems initially spent more on Whites. When systems initially spent more on African Americans, relative increases were greater for Whites for outpatient and emergency services. CONCLUSIONS: With new funding that requires no matching funds from the county, county mental health systems did reduce outpatient treatment expenditure inequalities. This was found to be true in counties that initially favored African Americans and in counties that initially favored Whites. Adopting a systems level perspective and taking account of initial conditions and trends can be critical for understanding inequalities.

Subsidized Marketplace Purchases Reduced Racial Disparities in Private Coverage Under the Affordable Care Act.

The Affordable Care Act's Marketplaces, by allowing subsidized purchase of insurance coverage by persons with incomes from the poverty line to middle income, and through active outreach and enrollment assistance efforts, are well situated to reduce large African American-white private coverage disparities. Using data from the National Health Interview Survey for multiyear periods before and after Affordable Care Act implementation, from 2011-2013 to 2015-2018, this study assessed how much disparity reduction occurred when Marketplaces were implemented. Analysis compared private coverage take-up by African Americans and whites for persons with incomes between 100 and 400% of the Federal Poverty Line (FPL), controlling for African American-white income differences and other covariates. African Americans' gains were significantly greater than whites' and disparities did close. However, both groups gained considerably less coverage than they might have, and some disparity remained. To make ongoing operations more effective and to guide future subsidy extensions and increases as enacted in the American Rescue Plan, more research is needed into the incentive value of subsidies and to discover which Marketplace outreach and enrollment assistance efforts were most effective. In advancing these aims, high priority should be given to identifying strategies that were particularly successful in reaching and engaging uninsured African Americans.

The Association of Learning Health System Practicing Hospitals and other Health Information Interested Hospitals with Patient-Generated Health Data Uptake.

Patient generated health data (PGHD) has been described as a necessary addition to provider-generated information for improving care processes in US hospitals. This study evaluated the distribution of Health Information Interested (HII) US hospitals that are more likely to capture or use PGHD. The literature suggests that HII hospitals are more likely to capture and use PGHD. Cross-sectional analysis of the 2018 American Hospital Association's (AHA) health-IT-supplement and other supporting datasets showed that HII hospitals collectively and majority of HII hospital subcategories evaluated were associated with increased PGHD capture and use. The full Learning Health System (LHS) hospital subcategory had the highest association and hospitals in the meaningful use stage three compliant (MU3) and PCORI funded subcategory also had higher rates of PGHD capture or use when in combination with LHS hospitals. Hence, being LHS appears to be the strongest practice and policy lever to increase PGHD capture and use.

Community paramedicine in Central Oregon: A promising model to reduce non-urgent emergency department utilization among medically complex Medicaid beneficiaries.

Background: Community paramedicine has emerged as a promising model to redirect persons with nonmedically emergent conditions to more appropriate and less expensive community-based health care settings. Outreach through community paramedicine to patients with a history of high hospital emergency department (ED) use and chronic health conditions has been found to reduce ED use. This study examined the effect of community paramedicine implemented in 2 rural counties in reducing nonemergent ED use among a sample of Medicaid beneficiaries with complex medical conditions and a history of high ED utilization. Methods: A cluster randomized trial approach with a stepped wedge design was used to test the effect of the community paramedicine intervention. ED utilization for non-urgent care was measured by emergency medicine ED visits and avoidable ED visits. Results: The community paramedicine intervention reduced ED utilization among a sample of 102 medically complex Medicaid beneficiaries with a history of high ED utilization. In the unadjusted models, emergency medical ED visits decreased by 13.9% (incidence rate ratio [IRR], 0.86; 95% confidence interval [CI], 0.76-0.98) or 6.1 visits saved for every 100 people. Avoidable emergency department visits decreased by 38.9% (IRR, 0.61; 95% CI, 0.44-0.84) or 2.3 visits saved for every 100 people. Conclusion: Our results suggest community paramedicine is a promising model to achieve a reduction in ED utilization among medically complex patients by managing complex health conditions in a home-based setting.

The use of individual and multilevel data in the development of a risk prediction model to predict patients' likelihood of completing colorectal cancer screening.

Promotion of colorectal cancer (CRC) screening can be expensive and unnecessary for many patients. The use of predictive analytics promises to help health systems target the right services to the right patients at the right time while improving population health. Multilevel data at the interpersonal, organizational, community, and policy levels, is rarely considered in clinical decision making but may be used to improve CRC screening risk prediction. We compared the effectiveness of a CRC screening risk prediction model that uses multilevel data with a more conventional model that uses only individual patient data. We used a retrospective cohort to ascertain the one-year occurrence of CRC screening. The cohort was determined from a Health Maintenance Organization, in Oregon. Eligible patients were 50-75 years old, health plan members for at least one year before their birthday in 2018 and were due for screening. We created a risk model using logistic regression first with data available in the electronic health record (EHR), and then added multilevel data. In a cohort of 59,249 patients, 36.1% completed CRC screening. The individual level model included 14 demographic, clinical and encounter based characteristics, had a bootstrap-corrected C-statistic of 0.722 and sufficient calibration. The multilevel model added 9 variables from clinical setting and community characteristics, and the bootstrap-corrected C-statistic remained the same with continued sufficient calibration. The predictive power of the CRC screening model did not improve after adding multilevel data. Our findings suggest that multilevel data added no improvement to the prediction of the likelihood of CRC screening.

The Evolution and Typology of Learning Health System Hospitals and other Health Information Interested Hospitals in the US.

This study identifies the type, distribution, and interactions of US hospitals that identify as electronic-data-driven, patient-centric, and learning-focused. Such facilities, termed Health Information Interested (HII) hospitals in this study, meet the defining criteria for one or more of the following designations: learning health systems (LHS), Health Information Technology for Economic and Clinical Health (HITECH) meaningful use stage three compliant (MU3), Patient-Centered Outcomes Research Institute (PCORI) funded, or medical home/safety net (MH/SN) hospital. The American Hospital Association (AHA) IT supplemental survey and other supporting data spanning 2013 to 2018 were used to identify HII hospitals. HII hospitals increased from 19.9 percent to 62.4 percent of AHA reporting hospitals from 2013 to 2018. HII subcategories in 2018 such as the full LHS (37.2 percent) and MU3 (46.9 percent) were dominant, with 33.2 percent having both designations. This indicates increased interest in patient-centric, learning-focused care using electronic health data. This information can enable health information management (HIM) professionals to be aware of programs or approaches that can facilitate learning-focused, patient-centric care using electronic health data within health systems.

The individual and program impacts of eliminating Medicaid dental benefits in the Oregon Health Plan.

OBJECTIVES: We determined how elimination of dental benefits among adult Medicaid beneficiaries in Oregon affected their access to dental care, Medicaid expenditures, and use of medical settings for dental services. METHODS: We used a natural experimental design using Medicaid claims data (n = 22 833) before and after Medicaid dental benefits were eliminated in Oregon in 2003 and survey data for continuously enrolled Oregon Health Plan enrollees (n = 718) covering 3 years after benefit cuts. RESULTS: Claims analysis showed that, compared with enrollees who retained dental benefits, those who lost benefits had large increases in dental-related emergency department use (101.7%; P < .001) and expenditures (98.8%; P < .001) and in all ambulatory medical care use (77.0%; P < .01) and expenditures (114.5%; P < .01). Survey results indicated that enrollees who lost dental benefits had nearly 3 times the odds (odds ratio = 2.863; P = .001) of unmet dental need, and only one third the odds (odds ratio = 0.340; P = .001) of getting annual dental checkups relative to those retaining benefits. CONCLUSIONS: Combined evidence from both analyses suggested that the elimination of dental benefits resulted in significant unmet dental health care needs, which led to increased use of medical settings for dental problems.

Racial/ethnic minority children's use of psychiatric emergency care in California's Public Mental Health System.

OBJECTIVES: We examined rates and intensity of crisis services use by race/ethnicity for 351,174 children younger than 18 years who received specialty mental health care from California's 57 county public mental health systems between July 1998 and June 2001. METHODS: We used fixed-effects regression for a controlled assessment of racial/ethnic disparities in children's use of hospital-based services for the most serious mental health crises (crisis stabilization services) and community-based services for other crises (crisis intervention services). RESULTS: African American children were more likely than were White children to use both kinds of crisis care and made more visits to hospital-based crisis stabilization services after initial use. Asian American/Pacific Islander and American Indian/Alaska Native children were more likely than were White children to use hospital-based crisis stabilization services but, along with Latino children, made fewer hospital-based crisis stabilization visits after an initial visit. CONCLUSIONS: African American children used both kinds of crisis services more than did White children, and Asian Americans/Pacific Islander and American Indians/Alaska Native children visited only when they experienced the most disruptive and troubling kind of crises, and made nonrecurring visits.

How effective are copayments in reducing expenditures for low-income adult Medicaid beneficiaries? Experience from the Oregon health plan.

OBJECTIVES: To determine the impact of introducing copayments on medical care use and expenditures for low-income, adult Medicaid beneficiaries. DATA SOURCES/STUDY SETTING: The Oregon Health Plan (OHP) implemented copayments and other benefit changes for some adult beneficiaries in February 2003. STUDY DESIGN: Copayment effects were measured as the "difference-in-difference" in average monthly service use and expenditures among cohorts of OHP Standard (intervention) and Plus (comparison) beneficiaries. DATA COLLECTION/EXTRACTION METHODS: There were 10,176 OHP Standard and 10,319 Plus propensity score-matched subjects enrolled during November 2001-October 2002 and May 2003-April 2004 that were selected and assigned to 59 primary care-based service areas with aggregate outcomes calculated in six month intervals yielding 472 observations. RESULTS: Total expenditures per person remained unchanged (+2.2 percent, p=.47) despite reductions in use (-2.7 percent, p<.001). Use and expenditures per person decreased for pharmacy (-2.2 percent, p<.001; -10.5 percent, p<.001) but increased for inpatient (+27.3 percent, p<.001; +20.1 percent, p=.03) and hospital outpatient services (+13.5 percent, p<.001; +19.7 percent, p<.001). Ambulatory professional (-7.7 percent, p<.001) and emergency department (-7.9 percent, p=.03) use decreased, yet expenditures remained unchanged (-1.5 percent, p=.75; -2.0 percent, p=.68, respectively) as expenditures per service user rose (+6.6 percent, p=.13; +7.9 percent, p=.03, respectively). CONCLUSIONS: In the Oregon Medicaid program applying copayments shifted treatment patterns but did not provide expected savings. Policy makers should use caution in applying copayments to low-income Medicaid beneficiaries.

How much does emergency department use affect the cost of Medicaid programs?

STUDY OBJECTIVE: Use of the emergency department (ED) is often assumed to be an important component of health care expenditures for Medicaid enrollees. We seek to quantify the absolute and percentage of total Medicaid expenditures associated with outpatient ED visits. METHODS: This retrospective study used 2002 data from Oregon's Medicaid program. ED expenditures were defined to include hospital, physician, and ancillary services associated with any ED visit not resulting in an inpatient admission. We estimated average monthly ED expenditures in absolute values and as a percentage of total medical expenditures. Multivariate models were used to assess the effect of demographic factors and eligibility status on ED spending and use. RESULTS: We analyzed expenditures for 544,729 individuals enrolled in the Oregon Medicaid program in 2002. Monthly ED-associated expenditures averaged $12.63 (95% confidence interval $12.50 to $12.77) per member, representing 6.8% of total medical expenditures. Ancillary services (laboratory tests and diagnostic imaging) accounted for 35% of ED spending. Spending for ED services was skewed; 50% of all ED expenditures could be attributed to 3.0% of enrollees who made multiple ED visits. CONCLUSION: ED expenses are a relatively small percentage of total medical spending by Medicaid enrollees. An aggressive policy to cut ED expenditures by 25% would reduce Medicaid expenditures by less than 2% per year. Actual savings would be even smaller if reduced ED utilization were offset by increased spending at the primary care level. Because the majority of Medicaid patients do not use the ED in a given year, efforts to reduce ED expenditures may be best accomplished through targeting selected enrollees who have high ED expenditures, rather than attempting to decrease overall ED use.

Denying postpartum sterilization to women with Emergency Medicaid does not reduce hospital charges.

BACKGROUND: To assess the change in hospital reimbursement resulting from a 2004 policy requiring immigrants with Emergency Medicaid (EM) to pay for sterilization following vaginal delivery, we examined rates of tubal ligation following vaginal [postpartum bilateral tubal ligation (PPBTL)] and cesarean [cesarean section with bilateral tubal ligation (CSBTL)] deliveries, and compared these to a Standard Medicaid (SM) population unaffected by the policy. STUDY DESIGN: Records of women who delivered at the Oregon Health and Science University between January 2000 and December 2006 were reviewed. Data examined included insurance, mode of delivery, sterilization and net revenue by delivery type. RESULTS: A total of 3612 SM patients and 4220 EM patients delivered in the 5 years before the policy, and 1628 SM patients and 2066 EM patients delivered in the 2 years after the policy. The incidence of PPBTL among EM patients delivering vaginally dropped from 9.9% prepolicy to 0.9% postpolicy (p<.01). Concurrently, CSBTL among EM patients having cesarean section increased from 18.8% prepolicy to 23.5% postpolicy (p=.03). Notably, no significant change in PPBTL (pre: 8.7%, post: 9.2%, p=1.0) or CSBTL (pre: 22.9%, post: 22.9%, p=.62) occurred in the SM group. The net revenue change for all deliveries with tubal ligations in the EM population postpolicy was -US$5284. CONCLUSION: Requiring out-of-pocket payment for sterilization following vaginal delivery in an EM population results in a decrease in PPBTL and an increase in CSBTL, and does not reduce hospital financial losses.

Factors that influence access to mental health services in South-Eastern Europe.

INTRODUCTION: Access to mental health (MH) services is unequal worldwide and changes are required in this respect. OBJECTIVES: Our aim was to identify the delay to the first psychiatry consult and to understand patients' characteristics and perspectives on the factors that may influence the delay, among a sample of participants from three Southeastern European Countries. MATERIALS AND METHODS: The WHO Pathway Encounter Form questionnaire was applied in 400 patients "new cases" and a questionnaire on the factors influencing the access was administered to the same patients, as well as to their caretakers and MH providers. RESULT AND DISCUSSIONS: The average profile of the patient "new case" was: married female older than 40 years, with an average economic status and no MH history. The mean delay was up to 3 months and the most important factors that were influencing the delay were stigma and lack of knowledge regarding MH problems and available current treatments. CONCLUSIONS: Future policies trying to improve the access to psychiatric care should focus on increasing awareness about MH problems in the general population.

Effects on outpatient and emergency mental health care of strict Medicaid early periodic screening, diagnosis, and treatment enforcement.

We investigated enforcement of mental health benefits provided by California Medicaid's Early Periodic Screening, Diagnosis, and Treatment (EPSDT) program. Enforcement, compelled by a consumer-driven lawsuit, resulted in an almost 4-fold funding increase over a 5-year period. We evaluated the impact of enforcement on outpatient treatment intensity (number of visits per child) and rates of emergency care treatment. Using fixed-effects regression, we examined the number of outpatient mental health visits per client and the percentage of all clients using crisis care across 53 autonomous California county mental health plans over 32 three-month periods (quarters; emergency crisis care rates) and 36 quarters (out-patient mental health visits). Enforcement of EPSDT benefits in accordance with federal law produced favorable changes in patterns of mental health service use, consistent with policy aims.

Social networks and their relationship to mental health service use and expenditures among Medicaid beneficiaries.

OBJECTIVE: This study examined the relationship between social networks and mental health services utilization and expenditures. METHODS: A sample of 522 Medicaid mental health consumers was randomly selected from the administrative records of Colorado's Department of Health Care Policy and Financing. The administrative records contain information on utilization of services and expenditures of Medicaid beneficiaries within Colorado's Mental Health Services. In addition to the administrative records, social network and psychosocial data were gathered through longitudinal survey interviews. The interviews were conducted at six-month intervals between 1994 and 1997. Measures used in the regression analysis included demographic characteristics, clinical diagnoses, the social network index, expenditures, and utilization variables. RESULTS: The social network index was positively associated with utilization of and expenditures for inpatient services in local hospitals but negatively associated with expenditures for inpatient services in state hospitals or outpatient services. Relationships with family were negatively related to expenditures for outpatient services. Relationships with friends were positively associated with utilization of and expenditures for psychiatric inpatient services in local hospitals. CONCLUSIONS: Consumers who had higher social network index scores utilized more inpatient psychiatric services in local hospitals and had higher expenditures than those who had lower scores. Consumers who had higher social network index scores also had lower expenditures for inpatient services in state hospitals and outpatient services than those who have lower scores. Findings suggest that social network is associated with mental health utilization and expenditures in various ways, associations that need to be researched further.

Oregon's Medicaid Reform And Transition To Global Budgets Were Associated With Reductions In Expenditures.

In 2012 Oregon initiated an ambitious delivery system reform, moving the majority of its Medicaid enrollees into sixteen coordinated care organizations, a type of Medicaid accountable care organization. Using claims data, we assessed measures of access, appropriateness of care, utilization, and expenditures for five service areas (evaluation and management, imaging, procedures, tests, and inpatient facility care), comparing Oregon to the neighboring state of Washington. Overall, the transformation into coordinated care organizations was associated with a 7 percent relative reduction in expenditures across the sum of these services, attributable primarily to reductions in inpatient utilization. The change to coordinated care organizations also demonstrated reductions in avoidable emergency department visits and improvements in some measures of appropriateness of care, but also exhibited reductions in primary care visits, a potential area of concern. Oregon's coordinated care organizations could provide lessons for controlling health care spending for other state Medicaid programs.

Early Performance in Medicaid Accountable Care Organizations: A Comparison of Oregon and Colorado.

Importance: Several state Medicaid reforms are under way, but the relative performance of different approaches is unclear. Objective: To compare the performance of Oregon's and Colorado's Medicaid Accountable Care Organization (ACO) models. Design, Setting, and Participants: Oregon initiated its Medicaid transformation in 2012, supported by a $1.9 billion investment from the federal government, moving most Medicaid enrollees into 16 Coordinated Care Organizations, which managed care within a global budget. Colorado initiated its Medicaid Accountable Care Collaborative in 2011, creating 7 Regional Care Collaborative Organizations that received funding to coordinate care with providers and connect Medicaid enrollees with community services. Data spanning July 1, 2010, through December 31, 2014 (18 months before intervention and 24 months after intervention, treating 2012 as a transition year) were analyzed for 452 371 Oregon and 330 511 Colorado Medicaid enrollees, assessing changes in outcomes using difference-in-differences analyses of regional focus, primary care homes, and care coordination. Oregon's Coordinated Care Organization model was more comprehensive in its reform goals and in the imposition of downside financial risk. Exposures: Regional focus, primary care homes, and care coordination in Medicaid ACOs. Main Outcomes and Measures: Performance on claims-based measures of standardized expenditures and utilization for selected services, access, preventable hospitalizations, and appropriateness of care. Results: In a total of 782 882 Medicaid enrollees, 45.0% were male, with mean (SD) age 16.74 (14.41) years. Standardized expenditures for selected services declined in both states during the 2010-2014 period, but these decreases were not significantly different between the 2 states. Oregon's model was associated with reductions in emergency department visits (-6.28 per 1000 beneficiary-months; 95% CI, -10.51 to -2.05) and primary care visits (-15.09 visits per 1000 beneficiary-months; 95% CI, -26.57 to -3.61), improvements in acute preventable hospital admissions (-1.01 admissions per 1000 beneficiary-months; 95% CI, -1.61 to -0.42), 3 of 4 measures of access (well-child visits, ages 3-6 years, 2.69%; 95% CI, 1.20% to 4.19%; adolescent well-care visits, 6.77%; 95% CI, 5.22% to 8.32%; and adult access to preventive ambulatory care, 1.26%; 95% CI, 0.28% to 2.25%), and 1 of 4 measures of appropriateness of care (avoidance of head imaging for uncomplicated headache, 2.59%; 95% CI, 1.35% to 3.83%). Conclusions and Relevance: Two years into implementation, Oregon's and Colorado's Medicaid ACO models exhibited similar performance on standardized expenditures for selected services. Oregon's model, marked by a large federal investment and movement to global budgets, was associated with improvements in some measures of utilization, access, and quality, but Colorado's model paralleled Oregon's on several other metrics.

The implementation of managed behavioral healthcare in Colorado and the effects on older Medicaid beneficiaries.

BACKGROUND: One of five persons over the age of 65 experiences a diagnosable form of mental illness. Yet their access to and use of specialty services are the lowest among all age groups. It is unclear how managed behavioral healthcare has affected this problematic situation. The Colorado Medicaid Mental Health Capitation Pilot Program, implemented in 1995, provided an opportunity to investigate the impact of managed behavioral healthcare on older Medicaid beneficiaries. STUDY AIMS: This study compared two capitated administrative models of Medicaid mental health service delivery to a traditional fee-for-service model, and specifically focused on how these models shaped service use and expenditure patterns for Medicaid beneficiaries over the age of 65. METHODS: This study employed a quasi-experimental, pre-post design with a non-equivalent comparison group that reflects the implementation of capitation financing in some parts of Colorado and not others. A difference in difference specification was used to identify the effects of capitation under two administrative models relative to areas remaining under fee-for-service reimbursement. Logistic and Ordinary Least Squares regression were used to estimate service use and (logged) expenditures per repeat and total number of service users. Generalized corrections for heteroskedasticity and repeated observations were applied. Probabilities and average user expenditures were derived from regression results with a fixed case-mix and compared to actuals. RESULTS: The analyses indicated that one of the capitated administrative models increased the total number of older beneficiaries who used services while the total number of service users decreased in the other capitated models. Both capitated models reduced repeat use and expenditures for specialty mental health services relative to the traditional FFS model. DISCUSSION: Capitation had the expected effect of reducing the duration and intensity of treatment. Clear differences between the two capitated administrative models emerged that appeared consistent with their management philosophies. Measured effects were limited to services covered by capitation and may have been influenced by the observational design. Overall results were somewhat different from those pertaining to younger populations studied in Colorado. IMPLICATIONS FOR HEALTH CARE PROVISION AND USE: While capitation clearly reduced total expenditures for older beneficiaries, its influence on specific treatment process measures such as user expenditures, repeat users and total users may vary considerably across treatment systems. Notably, capitation may result in increases or decreases in total users within a specific sub-population such as elders. IMPLICATIONS FOR HEALTH POLICIES: This analysis provides critical information for those state mental health and Medicaid agencies that are expanding the application of managed behavioral healthcare within a demographic environment where the population of older adults with mental illnesses is increasing. Financing, organization and their impact on specific treatment populations need to be considered in developing and applying managed behavioral health care. IMPLICATIONS FOR FURTHER RESEARCH: The differential effects on elders by administrative models needs further explication and should be measured against clinical and social outcomes as well as the effect of other sources of financing and service substitution.

Medication treatment patterns for adults with schizophrenia in Medicaid managed care in Colorado.

OBJECTIVE: This study investigated the impact of Colorado's Medicaid mental health managed care program on patterns of antipsychotic medication treatment among persons with a diagnosis of schizophrenia. These patterns were compared with patterns of psychosocial treatment and a measure of symptom change. METHODS: Changes in study measures over time in two areas of the state where the policy intervention was implemented were compared with changes in measures in areas where it was not implemented. The study sample consisted of 235 consumers. Measures of antipsychotic medication treatment included any use in a given period, months in which a prescription was filled, and use of second-generation antipsychotics. Psychosocial treatment was measured by any use and expenditures per user. The schizophrenia subscale of the Brief Psychiatric Rating Scale was used to measure consumer outcomes. RESULTS: Probabilities of antipsychotic use in the managed care areas were stable or increased compared with the other areas. The average number of months with filled prescriptions was unchanged. Consumers served under managed care were less likely to use psychosocial treatment, and additional decreases in treatment costs were noted in one area. Difference scores for the schizophrenia subscale showed no change or positive effects for the managed care areas. CONCLUSIONS: Within the Colorado managed care program, antipsychotic medication therapy was not impaired, despite significant decreases in the continuity or intensity of psychosocial treatment, and no reduction in symptom levels was noted. Mental health managed care does not inherently impair medication therapy. Patterns of medication use appeared to be better indicators of program success than psychosocial treatment patterns and were more consistent with outcomes.
