Programmatic Support for Peer Specialists that Serve Transition Age Youth Living with Serious Mental Illness: Perspectives of Program Managers from Two Southern California Counties

Peer Specialists (PS) often work in outpatient mental health programs serving transition age youth (TAY). This study examines program managers' perspectives on efforts to strengthen PS' professional development. In 2019, we interviewed program managers (n = 11) from two Southern California Counties employed by public outpatient mental health programs (n = 8) serving TAY and conducted thematic analyses. We present themes and illustrative quotes. PS' roles are highly flexible; thus, PM support PS to strengthen skills to address organization-facing and client-facing responsibilities. PM addressed time management, documentation, PS integration into the organization, and workplace relationships. Trainings to better support clients included addressing cultural competency to serve LGBTQ TAY and racial/ethnic subgroups. Diverse supervision modalities address PS' diverse needs. Supporting PS' technical and administrative skills (e.g., planning, interpersonal communication skills) may aid their implementation of a complex role. Longitudinal research can examine the impact of organizational supports on PS' job satisfaction, career trajectories, and TAY clients' engagement with services.

Clinical and financial outcome impacts of comprehensive geriatric assessment in a level 1 geriatric emergency department

BACKGROUND

The aging population has led to an increase in emergency department (ED) visits by older adults who have complex medical conditions and high social needs. The purpose of this study was to assess if comprehensive geriatric evaluation and management impacted service utilization and cost by older adults admitted to the ED.

METHODS

This is a retrospective matched case-control study at a level 1 geriatric ED (GED) from January 1, 2018-March 31, 2020. Geriatric nurse specialists (GENIEs) provided comprehensive evaluations and management for GED patients. Propensity score matching was used to match patients receiving GENIE consultations to ED patients who did not receive a GENIE consult. Regression was used to assess the impact of the GENIE services on inpatient admissions, ED revisits and cost of inpatient and ED care from the payor perspective.

RESULTS

GENIE consults were associated with a 13.0% reduction in absolute risk of admission through the ED at index (95% confidence interval [CI] -17.0%, -9.0%, p < 0.001) and a reduction in risk for total admissions at 30 and 90-days post discharge (-11.3%, 95% CI -15.6%, -7.1%, p-value < 0.001; and -10.0, 95% CI -13.8%, -6.0%; p < 0.001 respectively), both driven by reduced risk of admission at the index visit. GENIE consults were associated with a 4% increase in absolute risk of revisits to the ED within 30 days (95% CI 0.6%, 7.3%; p = 0.001). GENIE consults were associated with a decrease in cost of inpatient and ED care, with savings of $2344 within 30 days (95% CI $2247, $2441, p < 0.001) and savings of $2004 USD within 90 days (95% CI $1895, $2114, p < 0.001), driven by reduced costs at the index visit.

CONCLUSIONS

GENIE consults were associated with decreased inpatient admissions through the ED, modestly increased ED revisits, and decreased cost of inpatient and ED care. The results of this study can be useful for EDs considering approaches to better serve older adults. They can also be of interest to payers as an area of potential cost savings.

Barriers to Accessing Mental Health Care Under the Mental Health Services Act: A Qualitative Case Study in Orange County, California

Despite progress made under California's Mental Health Services Act, limited access to care for cultural and linguistic minority groups remains a serious issue in community mental health. In this qualitative study we report findings from a large-scale community-level assessment that explored barriers to accessing care from the perspectives of multiple stakeholders including county advisors, advocates, community members, and consumers representing a range of cultural and linguistic communities in Orange County, California. We conducted 14 focus groups with N = 112 participants. Qualitative analysis revealed that system fragmentation, limited availability of linguistically appropriate care, and stigma continue to undermine access to mental health care. Peer health navigation and culturally responsive peer support are potential ways to promote service engagement with persons from cultural and linguistic minority groups that encounter barriers when accessing mental health services.

Dulce Digital-Me: protocol for a randomized controlled trial of an adaptive mHealth intervention for underserved Hispanics with diabetes

BACKGROUND

By 2034, the number of US individuals with diabetes is predicted to increase from 23.7 to 44.1 million, and annual diabetes-related spending is expected to grow from $113 to $336 billion. Up to 55% of US Hispanics born in the year 2000 are expected to develop diabetes during their lifetime. Poor healthcare access and cultural barriers prevent optimal care, adherence, and clinical benefit, placing Hispanics at disproportionate risk for costly diabetes complications. Mobile technology is increasingly prevalent in all populations and can circumvent such barriers. Our group developed Dulce Digital, an educational text messaging program that improved glycemic control relative to usual care. Dulce Digital-Me (DD-Me) has been tailored to a participant's individual needs with a greater focus on health behavior change.

METHODS

This is a three-arm, parallel group, randomized trial with equal allocation ratio enrolling Hispanic adults with low income and poorly managed type 2 diabetes (N = 414) from a San Diego County Federally Qualified Health Center. Participants are randomized to receive Dulce Digital, Dulce Digital-Me-Automated, or Dulce Digital-Me-Telephonic. The DD-Me groups include Dulce Digital components plus personalized goal-setting and feedback delivered via algorithm-driven automated text messaging (DD-Me-Automated) or by the care team health coach (DD-Me-Telephonic) over a 12-month follow-up period. The study will examine the comparative effectiveness of the three groups in improving diabetes clinical control [HbA1c, primary outcome; low-density lipoprotein cholesterol (LDL-C), and systolic blood pressure (SBP)] and patient-provider communication and patient adherence (i.e., medication, self-management tasks) over 12 months and will examine cost-effectiveness of the three interventions.

DISCUSSION

Our comparative evaluation of three mHealth approaches will elucidate how technology can be integrated most effectively and efficiently within primary care-based chronic care model approaches to reduce diabetes disparities in Hispanics and will assess two modes of personalized messaging delivery (i.e., automated messaging vs. telephonic by health coach) to inform cost and acceptability.

Developing trauma resilient communities through community capacity-building

BACKGROUND

Trauma is a significant public health issue, negatively impacting a range of health outcomes. Providers and administrators in public mental health systems recognize the widespread experience of trauma, as well as their limited ability to address trauma within their communities. In response, the Los Angeles County Department of Mental Health funded nine regionally based community partnerships to build capacity to address trauma. We describe partnership and community capacity-building efforts and examine community impact, defined as successful linkages to resources and changes in stress tolerance capacities among community members.

METHODS

We conceptualized community capacity-building as dissemination of trauma-informed education and training, community outreach and engagement, and linkage of community members to resources. We measured trauma-informed trainings among partnership members (N = 332) using the Trauma-Informed Organizational Toolkit. Outreach, engagement and linkages were documented using Event and Linkage Trackers. We examined changes in the type of successful linkage after the issuance of statewide mandatory restrictions in response to COVID-19. We examined changes in stress tolerance capacities among community members (N = 699) who were engaged in ongoing partnership activities using the 10-item Conner-Davidson Resilience Scale; the 28-item Coping Orientation to Problems; and the pictorial Inclusion of Community in Self Scale.

RESULTS

Training and education opportunities were widespread: 66% of members reported opportunities for training in 13 or more trauma-informed practices. Partnerships conducted over 7800 community capacity-building events with over 250,000 attendees. Nearly 14,000 successful linkages were made for a wide range of resources, with consistent linkage success prior to (85%) and during (87%) the pandemic. In response to COVID-19, linkage type significantly shifted from basic services and health care to food distribution (p < .01). Small but significant improvements occurred in coping through emotional and instrumental support; and sense of community connectedness (p < .05 each).

CONCLUSIONS

Community-based partnerships demonstrated effective capacity-building strategies. Despite the pandemic, community members did not report reduced stress tolerance, instead demonstrating gains in external help-seeking (use of emotional and instrumental supports) and perception of community connectedness. Future work will use qualitative methods to examine the impact of community capacity-building and the sustainability of this approach for addressing the impact of trauma within communities.

Roles of peer specialists and use of mental health services among youth with serious mental illness

AIM

To examine whether roles of peer specialists affect service use among Black, Latinx and White youth ages 16-24 with serious mental illness (SMI) in Los Angeles and San Diego Counties.

METHODS

Administrative data from 2015 to 2018 was used to summarize service use among 6329 transition age youth age 16-24 with SMI who received services from 76 outpatient public mental health programs with peer specialists on staff. Roles of peer specialists were assessed via a program survey. Generalized linear models were used to assess the relationship between peer specialist characteristics and service use outcomes (ie, outpatient and inpatient).

RESULTS

Having a transition age youth peer specialist on staff (vs older peer specialists) and having peer specialists that provide four or more services (vs fewer services) was associated with an increase in annual outpatient visits in both counties (P = <.001 each). In Los Angeles County, having three or more peer specialist trainings (vs fewer trainings) was associated with lower use of inpatient services (P < .001). In San Diego County, having a transition age youth peer specialist and peer specialists that provide four or more services was associated with lower use of inpatient services (P < .001 each).

CONCLUSIONS

Types of peer support and number of types of peer services were associated with mental health service utilization. Detailed examination of the roles of peer specialists is merited to identify the specific pathways that improve outcomes.

Oral Corticosteroids and Risk of Preterm Birth in the California Medicaid Program

BACKGROUND

There is limited information regarding the impact of dose and gestational timing of oral corticosteroid (OCS) use on preterm birth (PTB), especially among women with asthma.

OBJECTIVES

To evaluate OCS dose and timing on PTB for asthma and, as a comparison, systemic lupus erythematosus (SLE).

METHODS

We used health care data from California Medicaid enrollees linked to birth certificates (2007-2013), identifying women with asthma (n = 22,084) and SLE (n = 1174). We estimated risk ratios (RR) for OCS cumulative dose trajectories and other disease-related medications before gestational day 140 and hazard ratios (HR) for time-varying exposures after day 139.

RESULTS

For asthma, PTB risk was 14.0% for no OCS exposure and 14.3%, 16.8%, 20.5%, and 32.7% in low, medium, medium-high, and high cumulative dose trajectory groups, respectively, during the first 139 days. The high-dose group remained associated with PTB after adjustment (adjusted RR [aRR]: 1.46; 95% confidence interval [CI]: 1.00, 2.15). OCS dose after day 139 was not clearly associated with PTB, nor were controller medications. For SLE, PTB risk for no OCS exposure was 24.9%, and it was 39.1% in low- and 61.2% in high-dose trajectory groups. aRR were 1.80 (95% CI: 1.34, 2.40) for high and 1.24 (95% CI: 0.97, 1.58) for low groups. Only prednisone equivalent dose >20 mg/day after day 139 was associated with increased PTB (adjusted HR: 2.54; 95% CI: 1.60, 4.03).

CONCLUSIONS

For asthma, higher OCS doses early in pregnancy, but not later, were associated with increased PTB. For SLE, higher doses early and later in pregnancy were associated with PTB.

Racial-Ethnic Differences in Service Use Patterns Among Young, Commercially Insured Individuals With Recent-Onset Psychosis

OBJECTIVE

The aim of this study was to investigate racial-ethnic differences in use of mental health services and antipsychotic medication in the year following the recent onset of a psychotic disorder and to examine the role of household income as a proxy for socioeconomic status.

METHODS

Deidentified administrative claims data from the OptumLabs Data Warehouse were used to identify 8,021 commercially insured individuals ages 14 through 30 with a recent-onset psychotic disorder (January 1, 2011, through December 31, 2015). The authors compared mental health service use among African-American (11.5%), Hispanic (11.0%), and non-Hispanic white (77.4%) individuals during the year following an index diagnosis and adjusted these analyses for household income.

RESULTS

The probability of any use of outpatient mental health services was lower among African-American (67.4%±1.4%) and Hispanic individuals (66.5%±1.5%) compared with non-Hispanic white patients (72.3%±0.6%; p<0.05 for each comparison). Among those who used services, African-American and Hispanic individuals had fewer mean outpatient mental health visits per year compared with non-Hispanic whites (9.7±0.7 and 10.2±0.7 versus 14.3±0.5, respectively, p<0.001 for each comparison). These racial-ethnic differences in service use remained after adjustment for household income.

CONCLUSIONS

Among young, commercially insured individuals using outpatient services following an index diagnosis of psychotic disorder, African Americans and Hispanics received less intensive outpatient mental health care than their non-Hispanic white counterparts. Amid the upsurge of early intervention programs, special attention should be paid to increasing access to mental health services for racial-ethnic minority groups.

Rehabilitation After Total Knee Arthroplasty: Do Racial Disparities Exist?

BACKGROUND

Racial disparities in functional outcomes after total knee arthroplasty (TKA) exist. Whether differences in rehabilitation utilization contribute to these disparities remains to be investigated.

METHODS

Among 8349 women enrolled in the prospective Women's Health Initiative cohort who underwent primary TKA between 2006 and 2013, rehabilitation utilization was determined through linked Medicare claims data. Postacute discharge destination (home, skilled nursing facility, and inpatient rehabilitation facility), facility length of stay, and number of home health physical therapy (HHPT) and outpatient physical therapy (OPPT) sessions were compared between racial groups.

RESULTS

Non-Hispanic black women had worse physical function (median score, 65 vs 70) and higher likelihood of disability (13.2% vs 6.9%) than non-Hispanic white women before surgery. After TKA, black women were more likely to be discharged postacutely to an institutional facility (64.3% vs 54.5%) than white women, were more likely to receive HHPT services (52.6% vs 47.8%), and received more HHPT and OPPT sessions. After stratification by postacute discharge setting, the likelihood of receipt of HHPT or OPPT services was similar between racial groups. No significant difference in receipt of HHPT or OPPT services was found after use of propensity score weighting to balance health and medical characteristics indicating severity of need for physical therapy services.

CONCLUSION

Rehabilitation utilization was generally comparable between black and white women who received TKA when accounting for need. There was no evidence of underutilization of post-TKA rehabilitation services, and thus disparities in post-TKA functional outcomes do not appear to be a result of inequitable receipt of rehabilitation care.

Service Use Following First-Episode Schizophrenia Among Commercially Insured Youth

OBJECTIVE

To investigate patterns of mental health service and antipsychotic use following a first-episode schizophrenia (FES) and to examine the role of the treatment setting in which individuals are first diagnosed.

METHOD

Analysis of de-identified administrative claims data from the OptumLabs Data Warehouse was used to identify 1450 privately insured youth and young adults aged 14 through 30 with FES from January 1, 2011 through December 31, 2015. Regression analysis was used to estimate the use of mental health services during the year following FES, by type of service and by site of index diagnosis.

RESULTS

In the year following FES, 79.7% of youth received outpatient mental health services and 35.8% filled a prescription for antipsychotic medication. Among service users, mean outpatient visits were 15.9 and mean antipsychotic fills were 8.3. Youth who received an index diagnosis of FES in an inpatient setting were more likely to fill an antipsychotic medication than youth with FES in other settings. Youth who received an index diagnosis of FES during a specialty mental health outpatient visit had greater use of outpatient mental health than youth who received their diagnosis during a primary care visit.

CONCLUSIONS

Despite evidence-based guidelines supporting outpatient psychosocial care and antipsychotic treatment for FES, one-fifth of this cohort did not use outpatient services and the majority did not fill any prescriptions for antipsychotic medications during the year following FES. Our findings provide renewed urgency to ongoing efforts to accelerate early identification and care coordination for youth with FES.

Exacerbations, Health Resource Utilization, and Costs Among Medicare Beneficiaries with Chronic Obstructive Pulmonary Disease Treated with Nebulized Arformoterol Following a Respiratory Event

BACKGROUND

Long-acting beta2-agonists (LABAs), with or without inhaled corticosteroids (ICSs), delivered by handheld inhalers or nebulizers are recommended as maintenance therapy in chronic obstructive pulmonary disease (COPD). This study evaluated exacerbations, health resource utilization (HRU), and costs among Medicare beneficiaries with COPD on handheld ICS+LABA who switched to nebulized arformoterol (ARF) or continued ICS+LABA following a respiratory event.

METHODS

Using Medicare claims, we identified beneficiaries with COPD (international classification of disease, 9th revision, clinical modification [ICD-9-CM] 490-492.xx, 494.xx, 496.xx) between 2010-2014 who had ≥ 1 year of continuous enrollment in Parts A, B, and D; ≥ 2 COPD-related outpatient visits ≥ 30 days apart or ≥ 1 hospitalization(s); ICS+LABA use 90-days before ARF initiation; and a respiratory event (COPD-related hospitalization or emergency department [ED] visit < 30 days before ARF initiation). Using propensity scores, 423 beneficiaries who switched to ARF were matched to 423 beneficiaries who continued on handheld ICS+LABA (controls). Difference-in-difference regression models examined outcomes at 180-days follow-up.

RESULTS

Beneficiaries who switched to ARF had 1.5 fewer exacerbations (p=0.015) but no difference in hospitalizations and ED visits compared to controls. Durable medical equipment (DME) costs were higher among ARF users than controls ($1590), yet total health care costs were similar due to cost offsets by ARF in pharmacy (-$794), inpatient (-$524), and outpatient care (-$65). ARF accounted for 55% ($886.63) of DME costs, with the remaining costs attributed to oxygen therapy ($428.10) and nebulized corticosteroids ($590.85).

CONCLUSIONS

Switching from handheld ICS+LABA to nebulized ARF resulted in fewer COPD exacerbations among Medicare beneficiaries. Nebulized LABAs may improve outcomes in selected patients with COPD.

Medication management patterns among Medicare beneficiaries with chronic obstructive pulmonary disease who initiate nebulized arformoterol treatment

Purpose: Global evidence-based treatment strategies for chronic obstructive pulmonary disease (COPD) recommend using long-acting bronchodilators (LABDs) as maintenance therapy. However, COPD patients are often undertreated. We examined COPD treatment patterns among Medicare beneficiaries who initiated arformoterol tartrate, a nebulized long-acting beta2 agonist (LABA), and identified the predictors of initiation. Methods: Using a 100% sample of Medicare administrative data, we identified beneficiaries with a COPD diagnosis (ICD-9 490-492.xx, 494.xx, 496.xx) between 2010 and 2014 who had ≥1 year of continuous enrollment in Parts A, B, and D, and ≥2 COPD-related outpatient visits within 30 days or ≥1 hospitalization(s). After applying inclusion/exclusion criteria, three cohorts were identified: (1) study group beneficiaries who received nebulized arformoterol (n=11,886), (2) a subset of the study group with no LABD use 90 days prior to initiating arformoterol (n=5,542), and (3) control group beneficiaries with no nebulized LABA use (n=220,429). Logistic regression was used to evaluate predictors of arformoterol initiation. Odds ratios (ORs), 95% confidence intervals (CIs), and p values were computed. Results: Among arformoterol users, 47% (n=5,542) had received no LABDs 90 days prior to initiating arformoterol. These beneficiaries were being treated with a nebulized (50%) or inhaled (37%) short-acting bronchodilator or a systemic corticosteroid (46%), and many received antibiotics (37%). Compared to controls, beneficiaries who initiated arformoterol were significantly more likely to have had an exacerbation, a COPD-related hospitalization, and a pulmonologist or respiratory therapist visit prior to initiation (all p<0.05). Beneficiaries with moderate/severe psychiatric comorbidity or dual-eligible status were significantly less likely to initiate arformoterol, as compared to controls (all p<0.05). Conclusion: Medicare beneficiaries who initiated nebulized arformoterol therapy had more exacerbations and hospitalizations than controls 90 days prior to initiation. Findings revealed inadequate use of maintenance medications, suggesting a lack of compliance with evidence-based treatment guidelines.

Integrated Primary Care in Assertive Community Treatment

Assertive community treatment (ACT) has the potential to serve as a medical home for adults with serious mental illness, a population that experiences some of the most significant health disparities in the United States. Using site visit methodology, the authors describe partnerships that were created between five ACT programs and federally qualified health centers (FQHCs) to provide integrated behavioral health and primary care. The authors examined rates of screening for common chronic conditions. The programs used three distinct approaches: two programs colocated ACT teams at an FQHC, two programs employed primary care providers who split their time between the FQHC and the ACT program, and one program embedded a primary care provider within the ACT team. Effective communication between staffs may be more important than type of partnership in determining integration success.

Implementation of Integrated Health Homes and Health Outcomes for Persons With Serious Mental Illness in Los Angeles County

OBJECTIVE

The Medicaid health home option of the Affordable Care Act provides a new opportunity to address the fragmented system of care for persons with serious mental illness. This study examined the implementation of integrated health homes in Los Angeles County.

METHODS

Longitudinal data on client-reported physical health status, clinician-reported mental health recovery, and screening for common chronic conditions among 1,941 persons enrolled in integrated care programs for serious mental illness and chronic general medical illness were combined with site visit data measuring the level of integration of general medical and mental health care among ten integrated care programs. Various analyses were used to compare outcomes by level of program integration (generalized estimating equations for physical health status and mental health recovery and logistic regression and chi-square tests for screening for common chronic conditions and clinical risk factors).

RESULTS

Clients in more highly integrated programs had greater improvements in physical health status and mental health recovery and higher rates of screening for common chronic conditions compared with clients in less integrated programs. They also had greater reductions in hypertension but a worrisome increase in prediabetes and diabetes.

CONCLUSIONS

Highly integrated mental health and general medical programs were associated with greater improvements in health outcomes compared with less integrated programs. Additional research is necessary to identify predictors of integration, to determine which aspects of integration drive improvements in health outcomes, and to identify strategies to increase integration within less integrated programs. Efforts are needed to coordinate pharmacotherapy, including increased consideration of the metabolic effects of antipsychotic medication.

Implementation of Age-Specific Services for Transition-Age Youths in California

OBJECTIVES

This study examined the implementation of age-specific services for transition-age youths in California under the Mental Health Services Act (MHSA).

METHODS

This study employed a sequential, exploratory mixed-methods design. Qualitative interviews with 39 mental health service area administrators in California were analyzed to develop an understanding of how the MHSA has facilitated the development of youth-specific programs or services. A quantitative survey of 180 youth-focused programs was also used to describe the range of services that were implemented, the use of evidence-based and promising practices, and the role of youths in the design, planning, delivery, and evaluation of services.

RESULTS

Administrators described the MHSA as providing a programmatic focus and financial support for youth-specific services, outlining a stakeholder process to create buy-in and develop a vision for services, and emphasizing the role of youths in service delivery and planning. Youth-specific programs implemented a diverse array of services, including general medical care; employment and education support; housing placement and support; and family, mentoring, and social support. Programs described implementing evidence-based and promising practices and involving youths in service planning, implementation, or quality improvement activities.

CONCLUSIONS

The MHSA has had a substantial impact on the landscape of youth-specific services in California by expanding both the number of programs and the diversity in types of services and by promoting the engagement of youths in the planning and delivery of services. Additional efforts are necessary to determine the extent to which youth-specific services yield greater improvements in youths' outcomes compared with services designed for adults.

Permanent Supportive Housing for Transition-Age Youths: Service Costs and Fidelity to the Housing First Model

OBJECTIVE

Permanent supportive housing (PSH) programs are being implemented nationally and on a large scale. However, little is known about PSH for transition-age youths (ages 18 to 24). This study estimated health services costs associated with participation in PSH among youths and examined the relationship between fidelity to the Housing First model and health service outcomes.

METHODS

Administrative data were used in a quasi-experimental, difference-in-differences design with a propensity score-matched contemporaneous control group to compare health service costs among 2,609 youths in PSH and 2,609 youths with serious mental illness receiving public mental health services in California from January 1, 2004, through June 30, 2010. Data from a survey of PSH program practices were merged with the administrative data to examine changes in service use among 1,299 youths in 63 PSH programs by level of fidelity to the Housing First model.

RESULTS

Total service costs increased by $13,337 among youths in PSH compared with youths in the matched control group. Youths in higher-fidelity programs had larger declines in use of inpatient services and larger increases in outpatient visits compared with youths in lower-fidelity programs.

CONCLUSIONS

PSH for youths was associated with substantial increases in costs. Higher-fidelity PSH programs may be more effective than lower-fidelity programs in reducing use of inpatient services and increasing use of outpatient services. As substantial investments are made in PSH for youths, it is imperative that these programs are designed and implemented to maximize their effectiveness and their impact on youth outcomes.

Implementation and Outcomes of Forensic Housing First Programs

This mixed-method study used administrative data from 68 supportive housing programs and evaluative and qualitative site visit data from a subset of four forensic programs to (a) compare fidelity to the Housing First model and residential client outcomes between forensic and nonforensic programs and (b) investigate whether and how providers working in forensic programs can navigate competing Housing First principles and criminal justice mandates. Quantitative findings suggested that forensic programs were less likely to follow a harm reduction approach to substance use and clients in those programs were more likely to live in congregate settings. Qualitative findings suggested that an interplay of court involvement, limited resources, and risk environments influenced staff decisions regarding housing and treatment. Existing mental health and criminal justice collaborations necessitate adaptation to the Housing First model to accommodate client needs.

Fidelity to the Housing First Model and Variation in Health Service Use Within Permanent Supportive Housing

OBJECTIVE

Permanent supportive housing (PSH) programs are being implemented throughout the United States. This study examined the relationship between fidelity to the Housing First model and health service use among clients in PSH programs in California.

METHODS

Data from a survey of PSH program practices were merged with administrative data on service utilization to examine the association between fidelity to a benchmark program, the Housing First model, and health service use among 5,067 clients in 77 PSH programs. Regression analyses were used to compare inpatient, crisis and residential, and outpatient mental health service use between high-, mid-, and low-fidelity programs in a pre-post design.

RESULTS

During the preenrollment period, clients in mid- and high-fidelity PSH programs, compared with low-fidelity programs, used inpatient and crisis and residential services more but used outpatient mental health services less. Postenrollment, patients in high-fidelity programs showed the largest increase in the number of outpatient visits, followed by clients in mid- and low-fidelity programs: 71.6 versus 48.2 and 29.0, respectively.

CONCLUSIONS

Clients in housing programs with higher fidelity to the Housing First model had greater increases in outpatient visits. Compared with lower-fidelity programs, higher-fidelity programs also enrolled clients who used fewer mental health outpatient services in the year before enrollment. Higher-fidelity programs may be more effective than lower-fidelity programs in increasing outpatient service utilization and in their outreach to and engagement of clients who are not appropriately served by the public mental health system.

Sorting Out the Health Risk in California's State-Based Marketplace

OBJECTIVE

To characterize the health risk of enrollees in California's state-based insurance marketplace (Covered California) by metal tier, region, month of enrollment, and plan.

DATA SOURCE/STUDY SETTING

2014 Open-enrollment data from Covered California linked with 2012 hospitalization and emergency department (ED) visit records from statewide all-payer administrative databases.

DATA COLLECTION/EXTRACTION METHODS

Chronic Illness and Disability Payment System (CDPS) health risk scores derived from an individual's age and sex from the enrollment file and the diagnoses captured in the hospitalization and ED records. CDPS scores were standardized by setting the average to 1.00.

PRINCIPAL FINDINGS

Among the 1,286,089 enrollees, 120,573 (9.4 percent) had at least one ED visit and/or a hospitalization in 2012. Higher risk enrollees chose plans with greater actuarial value. The standardized CDPS health risk score was 11 percent higher in the first month of enrollment (1.08; 99 percent CI: 1.07-1.09) than the last month (0.97; 99 percent CI: 0.97-0.97). Four of the 12 plans enrolled 91 percent of individuals; their average health risk scores were each within 3 percent of the marketplace's statewide average.

CONCLUSIONS

Providing health plans with a means to assess the health risk of their year 1 enrollees allowed them to anticipate whether they would receive or contribute payments to a risk-adjustment pool. After receiving these findings as a part of their negotiations with Covered California, health plans covering the majority of enrollees decreased their initially proposed 2015 rates, saving consumers tens of millions of dollars in potential premiums.

Psychiatric readmissions in a community-based sample of patients with mental disorders

OBJECTIVE

This study examined whether receipt of outpatient psychiatric services after hospital discharge was associated with reduced risk of readmission.

METHODS

Treatment records from patients admitted to San Diego County psychiatric hospitals over a one-year period were obtained from the San Diego County Behavioral Health Services electronic health record system. A discrete-time proportional hazards model was used to examine the association of receipt of outpatient psychiatric services with readmission within 30 days of discharge from the index hospitalization.

RESULTS

Of the 4,663 patients, 16% were readmitted within 30 days. In an adjusted model, receipt of outpatient therapy after discharge was associated with a greater likelihood of being readmitted (hazard ratio=1.36, 95% confidence interval=1.14-1.67), whereas receipt of case management or medication management was not associated with readmission.

CONCLUSIONS

The differential risk of readmission by service type suggests a need for studies that explore reasons for an increased risk of readmission with certain types of services.

Aging in place within permanent supportive housing

OBJECTIVES

This study examined whether and how permanent supportive housing (PSH) programs are able to support aging in place among tenants with serious mental illness.

DESIGN

Investigators used a mixed-method approach known as a convergent parallel design in which quantitative and qualitative data are analyzed separately and findings are merged during interpretation. Quantitative analysis compared 1-year pre-residential and post-residential outcomes for PSH program enrollees, comparing adults aged 35-49 years (n = 3990) with those aged 50 years or older (n = 3086). Case study analysis using qualitative interviews with staff of a PSH program that exclusively served older adults identified challenges to providing support services.

RESULTS

Substantial declines in days spent homeless and in justice system settings were found, along with increases in days living independently in apartments and in congregate settings. Homelessness and justice system involvement declined less for older adults than younger adults. Qualitative themes related to working with older adults included increased attention to medical vulnerability, residual effects of institutional care, and perceived preference for congregate living.

CONCLUSIONS

PSH is an effective way to end homelessness, yet little is known about how programs can support housing stability among aging populations. Additional support and training for PSH staff will better promote successful aging in place.

Fidelity to the housing first model and effectiveness of permanent supported housing programs in California

OBJECTIVES

Permanent supported housing programs are being implemented throughout the United States. This study examined the relationship between fidelity to the Housing First model and residential outcomes among clients of full service partnerships (FSPs) in California.

METHODS

This study had a mixed-methods design. Quantitative administrative and survey data were used to describe FSP practices and to examine the association between fidelity to Housing First and residential outcomes in the year before and after enrollment of 6,584 FSP clients in 86 programs. Focus groups at 20 FSPs provided qualitative data to enhance the understanding of these findings with actual accounts of housing-related experiences in high- and low-fidelity programs.

RESULTS

Prior to enrollment, the mean days of homelessness were greater at high- versus low-fidelity (101 versus 46 days) FSPs. After adjustment for individual characteristics, the analysis found that days spent homeless after enrollment declined by 87 at high-fidelity programs and by 34 at low-fidelity programs. After adjustment for days spent homeless before enrollment, days spent homeless after enrollment declined by 63 at high-fidelity programs and by 53 at low-fidelity programs. After enrollment, clients at high-fidelity programs spent more than 60 additional days in apartments than clients at low-facility programs. Differences were found between high- and low-fidelity FSPs in client choice in housing and how much clients' goals were considered in housing placement.

CONCLUSIONS

Programs with greater fidelity to the Housing First model enrolled clients with longer histories of homelessness and placed most of them in apartments.

Full-service partnerships among adults with serious mental illness in California: impact on utilization and costs

OBJECTIVE

California's full-service partnerships (FSPs) provide a combination of subsidized permanent housing and multidisciplinary team-based services with a focus on rehabilitation and recovery. The goal of the study was to examine whether participation in FSPs is associated with changes in health service use and costs compared with usual care.

METHODS

A quasi-experimental, pre-post, intent-to-treat design with a propensity score-matched contemporaneous control group was used to compare health service use and costs among 10,231 FSP clients and 10,231 matched clients with serious mental illness who were receiving public mental health services in California from January 1, 2004, through June 30, 2010.

RESULTS

Among FSP participants, the mean annual number of mental health outpatient visits increased by 55.5, and annual mental health costs increased by $11,725 relative to the matched control group. Total service costs increased by $12,056.

CONCLUSIONS

Participation in an FSP was associated with increases in outpatient visits and their associated costs. As supportive housing programs are implemented nationally and on a large scale, these programs will likely need to be more effectively designed and targeted in order to achieve reductions in costly inpatient services.

Impact of hypertension on healthcare costs among children

OBJECTIVES

Despite the significant prevalence of elevated blood pressure (BP) and body mass index (BMI) in children, few studies have assessed their combined impact on healthcare costs. This study estimates healthcare costs related to BP and BMI in children and adolescents.

STUDY DESIGN

Prospective dynamic cohort study of 71,617 children aged 3 to 17 years with 208,800 child years of enrollment in integrated health systems in Colorado or Minnesota between January 1, 2007, and December 31, 2011.

METHODS

Generalized linear models were used to calculate standardized annual estimates of total, inpatient, outpatient, and pharmacy costs, outpatient utilization, and receipt of diagnostic and evaluation tests associated with BP status and BMI status. Results: Total annual costs were significantly lower in children with normal BP ($736, SE = $15) and prehypertension ($945, SE = $10) than children with hypertension ($1972, SE = $74) (P <.001, each comparison), adjusting for BMI. Total annual cost for children below the 85th percentile of BMI ($822, SE = $8) was significantly lower than for children between the 85th and 95th percentiles ($954, SE = $45) and for children at or above the 95th percentile ($937, SE = $13) (P <.001, each), adjusting for HT.

CONCLUSIONS

This study shows strong associations of prehypertension and hypertension, independent of BMI, with healthcare costs in children. Although BMI status was also statistically significantly associated with costs, the major influence on cost in this large cohort of children and adolescents was BP status. Costs related to elevated BMI may be systematically overestimated in studies that do not adjust for BP status.

Variation in the implementation of California's Full Service Partnerships for persons with serious mental illness

OBJECTIVE

This study examined variation in the implementation of California's Full Service Partnerships (FSPs), which are supported housing programs that do "whatever it takes" to improve outcomes among persons with serious mental illness who are homeless or at risk of homelessness.

DATA SOURCES/SETTING

Ninety-three FSPs in California.

STUDY DESIGN

A mixed methods approach was selected to develop a better understanding of the complexity of the FSP programs. The design structure was a combined explanatory and exploratory sequential design (qual→QUAN→qual) where a qualitative focus group was used to develop a quantitative survey that was followed by qualitative site visits. The survey was used to describe the breadth of variation based on fidelity to the Housing First model, while the site visits were used to provide a depth of information on high- versus low-fidelity programs.

PRINCIPAL FINDINGS

We found substantial variation in implementation among FSPs. Fidelity was particularly low along domains related with housing and service philosophy, indicating that many FSPs implemented a rich array of services but applied housing readiness requirements and did not adhere to consumer choice in housing.

CONCLUSIONS

There remains room for improvement in the recovery-orientation of FSPs. Fortunately, we have identified several processes by which program managers and counties can increase the fidelity of their programs.

Development and validation of a Housing First fidelity survey

OBJECTIVES

Programs that use the Housing First model are being implemented throughout the United States and internationally. The authors describe the development and validation of a Housing First fidelity survey.

METHODS

A 46-item survey was developed to measure fidelity across five domains: housing process and structure, separation of housing and services, service philosophy, service array, and team structure. The survey was administered to staff and clients of 93 supported-housing programs in California. Exploratory and confirmatory factor analyses were used to identify the items and model structure that best fit the data.

RESULTS

Sixteen items were retained in a two-factor model, one related to approach to housing, separation of housing and services, and service philosophy and one related to service array and team structure.

CONCLUSIONS

Our survey mapped program practices by using a common metric that captured variation in fidelity to Housing First across a large-scale implementation of supported-housing programs.

Change in mental health service use after offering youth-specific versus adult programs to transition-age youths

OBJECTIVES

This study examined changes in service use associated with providing age-specific services for youths in their transitional years, ages 18–24.

METHODS

A quasi-experimental, difference-in-difference design with propensity score weighting was used to compare mental health service utilization (use of outpatient, inpatient, emergency, and justice system services) among 931 youths enrolled in outpatient programs specifically for transition-age youths and 1,574 youths enrolled in standard adult outpatient programs in San Diego County, California, from July 2004 through December 2009.

RESULTS

Among youths enrolled in outpatient programs geared toward youths of transitional age, the mean number of annual outpatient mental health visits increased by 12.2 (p<.001) compared with youths enrolled in standard adult outpatient programs.

CONCLUSIONS

Compared with traditional adult outpatient mental health programs, age-specific programs were associated with an increased use of outpatient mental health services. Future research is needed to assess the effectiveness of age-specific programs for transition-age youths and how use of these programs relates to improved clinical, educational, and vocational outcomes over time.

Cost-effectiveness of an electronic medical record based clinical decision support system

BACKGROUND AND OBJECTIVE

Medical groups have invested billions of dollars in electronic medical records (EMRs), but few studies have examined the cost-effectiveness of EMR-based clinical decision support (CDS). This study examined the cost-effectiveness of EMR-based CDS for adults with diabetes from the perspective of the health care system.

DATA SOURCES/SETTING

Clinical outcome and cost data from a randomized clinical trial of EMR-based CDS were used as inputs into a diabetes simulation model. The simulation cohort included 1,092 patients with diabetes with A1c above goal at baseline.

STUDY DESIGN

The United Kingdom Prospective Diabetes Study Outcomes Model, a validated simulation model of diabetes, was used to evaluate remaining life years, quality-adjusted life years (QALYs), and health care costs over patient lifetimes (40-year time horizon) from the health system perspective.

PRINCIPAL FINDINGS

Patients in the intervention group had significantly lowered A1c (0.26 percent, p = .014) relative to patients in the control arm. Intervention costs were $120 (SE = 45) per patient in the first year and $76 (SE = 45) per patient in the following years. In the base case analysis, EMR-based CDS increased lifetime QALYs by 0.04 (SE = 0.01) and increased lifetime costs by $112 (SE = 660), resulting in an incremental cost-effectiveness ratio of $3,017 per QALY. The cost-effectiveness of EMR-based CDS persisted in one-way, two-way, and probabilistic sensitivity analyses.

CONCLUSIONS

Widespread adoption of sophisticated EMR-based CDS has the potential to modestly improve the quality of care for patients with chronic conditions without substantially increasing costs to the health care system.

Assessing needs for mental health and other services among transition-age youths, parents, and providers

OBJECTIVES

This qualitative study assessed the needs for mental health and other services among transition-age youths who were receiving services in youth-specific programs.

METHODS

Thirteen focus groups were conducted between June 2008 and January 2009. The purposefully sampled participants included transition-age youths age 18 to 24 who were receiving services in youth-specific programs (N=75, eight groups), parents of transition-age youths (N=14, two groups), and providers in the youth-specific programs (N=14, three groups). The qualitative analysis used an inductive approach in which investigators focused on generating themes and identifying relationships between themes. Through a process of repeated comparisons, the categories were further condensed into broad themes illustrating service needs.

RESULTS

Youths expressed needs for improved scheduling of services, stronger patient-provider relationships, and group therapies that address past experiences of violence, loss, and sexual abuse and that provide skills for developing and nurturing healthy relationships. Parents and providers expressed needs for increased community-based and peer-led services. Youths, parents, and providers all expressed needs for more housing options and for mentors with similar life experiences who could serve as role models, information brokers, and sources of social support for youths who were pursuing education and employment goals.

CONCLUSIONS

Findings from the focus groups suggest that there is room for improvement in the provision of services that are relevant to the current needs and life experiences of transition-age youths. Even within age-specific programs, improvements in services are needed to foster transitions to independence.

Differences in the volume of services and in prices drive big variations in Medicaid spending among US states and regions

It is well known that Medicaid spending per beneficiary varies widely across states. However, less is known about the cause of this variation, or about whether increased spending is associated with better outcomes. In this article we describe and analyze sources of interstate variation in Medicaid spending over several years. We find substantial variations both in the volume of services and in prices. Overall, per capita spending in the ten highest-spending states was $1,650 above the average national per capita spending, of which $1,186, or 72 percent, was due to the volume of services delivered. Spending in the ten lowest-spending states was $1,161 below the national average, of which $672, or 58 percent, was due to volume. In the mid-Atlantic region, increased price and volume resulted in the most expensive care among regions, whereas reduced price and volume in the South Central region resulted in the least expensive care among regions. Understanding these variations in greater detail should help improve the quality and efficiency of care-a task that will become more important as Medicaid is greatly expanded under the Affordable Care Act of 2010.

Evaluating a measure of social health derived from two mental health recovery measures: the California Quality of Life (CA-QOL) and Mental Health Statistics Improvement Program Consumer Survey (MHSIP)

Social health is important to measure when assessing outcomes in community mental health. Our objective was to validate social health scales using items from two broader commonly used measures that assess mental health outcomes. Participants were 609 adults receiving psychological treatment services. Items were identified from the California Quality of Life (CA-QOL) and Mental Health Statistics Improvement Program (MHSIP) outcome measures by their conceptual correspondence with social health and compared to the Social Functioning Questionnaire (SFQ) using correlational analyses. Pearson correlations for the identified CA-QOL and MSHIP items with the SFQ ranged from .42 to .62, and the identified scale scores produced Pearson correlation coefficients of .56, .70, and, .70 with the SFQ. Concurrent validity with social health was supported for the identified scales. The current inclusion of these assessment tools allows community mental health programs to include social health in their assessments.

Antiretroviral therapy adherence, medication use, and health care costs during 3 years of a community pharmacy medication therapy management program for Medi-Cal beneficiaries with HIV/AIDS

BACKGROUND

The types of pharmacist-provided medication therapy management (MTM) services provided to patients with human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) and the effects of MTM on medication adherence and patient outcomes have only recently begun to be studied. Although available studies suggest that patients receiving MTM services have better antiretroviral therapy (ART) adherence and outcomes, only 1 study has examined a large group of patients with HIV/AIDS, and none has examined adherence or outcomes for more than 1 year. A pilot program conducted by the California Department of Health Care Services (DHCS) and Medi-Cal (California's Medicaid program) provided an opportunity to examine ART adherence and outcomes in a large patient population receiving MTM services in community pharmacies over 3 years.

OBJECTIVES

To examine an HIV/AIDS pharmacy MTM compensation pilot program over a 3-year period (2005- 2007) in a sample of Medi-Cal beneficiaries by describing the associations between use of pilot pharmacies and (a) adherence to ART regimens; (b) medication utilization, including number and type of ART medication regimens and use of contraindicated ART regimens; (c) occurrence of opportunistic infections; and (d) all-cause pharmacy and medical costs.

METHODS

This was a cohort study examining Medi-Cal pharmacy and medical claims data (2005-2007) for patients with HIV/AIDS who were served by pilot pharmacies versus other (nonpilot) pharmacies. The study groups, pilot and nonpilot pharmacy patients with HIV/AIDS, consisted of Medi-Cal beneficiaries aged 18 years or older as of January 1, 2005, who were continuously enrolled from January 1, 2004, through December 31, 2007, and who received both a diagnosis of HIV/AIDS and at least 1 ART pharmacy claim during both the index period (2004) and the study period (January 1, 2005, through December 31, 2007). Pilot pharmacy patients were identified as having filled 50% or more of their ART prescriptions each year at 1 of the 10 pilot pharmacies. Patients for whom comprehensive medication data were not available, including those enrolled in managed care plans and/or Medicare, were excluded. Adherence was defined as a medication possession ratio (MPR) of 80%-120% and excess medication fills as MPR greater than 120%. Logistic regression was used to investigate the factors associated with adherence. Comparisons were made between groups using bivariate statistics (Pearson chi-square for categorical variables and t-tests for continuous variables). For comparisons of costs, generalized linear models were used including predictor variables for age, gender, and race/ethnicity. RESEARCH RESULTS: The study sample consisted of 2,234 patients meeting the study inclusion criteria. The proportion of study patients receiving the majority of their prescription medications (ART plus non-ART) at pilot pharmacies was 19.7% in 2005 and increased to 27.6% in 2006 and 28.1% in 2007. The demographic profile of pilot pharmacy patients was similar to that of patients receiving medications at nonpilot pharmacies, except that pilot pharmacies had a higher proportion of Latino patients (e.g., 19.7% vs. 14.9% in 2007, respectively, P = 0.006). A greater percentage of pilot than nonpilot pharmacy patients were adherent to their ART medication regimens (e.g., 2007: 69.4% vs. 47.3%, respectively, P < 0.001). After controlling for age, gender, and ethnicity/race in logistic regression analysis, use of a pilot pharmacy (odds ratio [OR] = 2.74, 95% CI = 2.44-3.10) was the most important factor associated with likelihood of adherence. Each year, pilot pharmacy patients were more likely than nonpilot pharmacy patients to remain on a single type of ART regimen (e.g., 2007: 71.7% vs. 49.1%, respectively, P < 0.001) and less likely to have excess fills (e.g., 2007: 12.9% vs. 35.5%, respectively, P < 0.001) and to use contraindicated regimens (e.g., 2007: 8.9% vs. 12.2%, respectively, P = 0.027). The percentages of patients experiencing opportunistic infections were similar between groups each year, approximately 35% (P = 0.809-0.945). In the generalized linear model analyses, the between-group differences in predicted mean (standard error [SE]) total health care costs per patient were not significantly different in any year (e.g., 2007: $38,983 [$1,023] vs. $38,856 [$633], respectively, P = 0.915). In each year, predicted non- ART medication costs were approximately 30%-40% greater in the pilot pharmacy than nonpilot pharmacy group (e.g., 2007: $10,815 [$538] vs. $8,190 [$252], respectively, P < 0.001); however, predicted expenditures for inpatient services were significantly lower (e.g., 2007: $3,083 [$293] vs. $5,186 [$300], respectively, P < 0.001). Payment from the DHCS Medi-Cal program for MTM services was approximately $1,000 per pilot pharmacy patient per year.

CONCLUSIONS

Over a 3-year period, patients at pilot pharmacies consistently had higher medication adherence rates, were more likely to remain on a single type of ART regimen throughout the year, had fewer excess fills, and used fewer contraindicated regimens than nonpilot pharmacy patients. There were no significant differences in mean total cost per patient per group, and the additional MTM services payment added less than 3% to the total cost.

Impact of electronic health record clinical decision support on diabetes care: a randomized trial

PURPOSE

We wanted to assess the impact of an electronic health record-based diabetes clinical decision support system on control of hemoglobin A(1c) (glycated hemoglobin), blood pressure, and low-density lipoprotein (LDL) cholesterol levels in adults with diabetes.

METHODS

We conducted a clinic-randomized trial conducted from October 2006 to May 2007 in Minnesota. Included were 11 clinics with 41 consenting primary care physicians and the physicians' 2,556 patients with diabetes. Patients were randomized either to receive or not to receive an electronic health record (EHR)-based clinical decision support system designed to improve care for those patients whose hemoglobin A(1c), blood pressure, or LDL cholesterol levels were higher than goal at any office visit. Analysis used general and generalized linear mixed models with repeated time measurements to accommodate the nested data structure.

RESULTS

The intervention group physicians used the EHR-based decision support system at 62.6% of all office visits made by adults with diabetes. The intervention group diabetes patients had significantly better hemoglobin A(1c) (intervention effect -0.26%; 95% confidence interval, -0.06% to -0.47%; P=.01), and better maintenance of systolic blood pressure control (80.2% vs 75.1%, P=.03) and borderline better maintenance of diastolic blood pressure control (85.6% vs 81.7%, P =.07), but not improved low-density lipoprotein cholesterol levels (P = .62) than patients of physicians randomized to the control arm of the study. Among intervention group physicians, 94% were satisfied or very satisfied with the intervention, and moderate use of the support system persisted for more than 1 year after feedback and incentives to encourage its use were discontinued.

CONCLUSIONS

EHR-based diabetes clinical decision support significantly improved glucose control and some aspects of blood pressure control in adults with type 2 diabetes.

Medication therapy management services in community pharmacy: a pilot programme in HIV specialty pharmacies

RATIONALE, AIMS AND OBJECTIVES

Pharmacist-provided medication therapy management services (MTMS) have been shown to increase patient's adherence to medications, improve health outcomes and reduce overall medical costs. The purpose of this study was to describe a pilot programme that provided pharmacy-based MTMS for patients with HIV/AIDS in the state of California, USA.

METHOD

Pharmacists from the 10 pilot pharmacies were surveyed using an online data collection tool. Information was collected to describe the types of MTMS offered, proportion of patients actively using specific MTMS, pharmacist beliefs regarding effect on patient outcomes and barriers to providing MTMS, ability to offer MTMS without pilot programme funding and specialized pharmacist or staff training.

RESULTS

Each responding pharmacy (7 of 10) varied in the number of HIV/AIDS patients served and prescription volume. All pharmacists had completed HIV/AIDS-related continuing education programmes, and some had other advanced training. The type of MTMS being offered varied at each pharmacy with 'individualized counselling by a pharmacist when overuse or underuse was detected' and 'refill reminders by telephone' being actively used by the largest proportion of patients. Most, but not all, pharmacists cited reimbursement as a barrier to MTMS provision. Pharmacists believed the MTMS they provide resulted in improved satisfaction (patient and provider), medication usage, therapeutics response and patient quality of life.

CONCLUSION

The type of MTMS offered, and proportion of patients actively using, varied among participating pilot pharmacies.

Effect of full-service partnerships on homelessness, use and costs of mental health services, and quality of life among adults with serious mental illness

CONTEXT

Chronically homeless adults with severe mental illness are heavy users of costly inpatient and emergency psychiatric services. Full-service partnerships (FSPs) provide housing and engage clients in treatment.

OBJECTIVE

To examine changes in recovery outcomes, mental health service use and costs, and quality of life associated with participation in FSPs.

DESIGN

A quasi-experimental, difference-in-difference design with a propensity score-matched control group was used to compare mental health service use and costs of FSP with public mental health services. Recovery outcomes were compared before and after services use, and quality of life was compared cross-sectionally.

SETTING

San Diego County, California, from October 2005 through June 2008.

PARTICIPANTS

Two hundred nine FSP clients and 154 clients receiving public mental health services.

MAIN OUTCOME MEASURES

Recovery outcomes (housing, financial support, and employment), mental health service use (use of outpatient, inpatient, emergency, and justice system services), and mental health services and housing costs from the perspective of the public mental health system.

RESULTS

Among FSP participants, the mean number of days spent homeless per year declined 129 days from 191 to 62 days; the probability of receiving inpatient, emergency, and justice system services declined by 14, 32, and 17 percentage points, respectively; and outpatient mental health visits increased by 78 visits (P < .001 each). Outpatient costs increased by $9180; inpatient costs declined by $6882; emergency service costs declined by $1721; jail mental health services costs declined by $1641; and housing costs increased by $3180 (P < .003 each). Quality of life was greater among FSP clients than among homeless clients receiving services in outpatient programs.

CONCLUSIONS

Participation in an FSP was associated with substantial increases in outpatient services and days spent in housing. Reductions in costs of inpatient/emergency and justice system services offset 82% of the cost of the FSP.

Mental illness, nativity, gender and labor supply

We analyzed the impacts of nativity and mental health (MH) on work by gender for non-elderly adults using the 2002 National Survey on Drug Use and Health. We employed two indicators of MH - the K6 scale of Mental Illness (MI) and an indicator for symptoms of Mania or Delusions (M/D). Instrumental variable (IV) models used measures of social support as instruments for MI. Unadjusted work rates were higher for immigrants (vs US-born adults). Regressions show that MI is associated with lower rates of work among US-born males but not immigrant males and females; M/D is associated lower rates of work among US-born males and females, and among immigrant males. Results did not change using IV models for MI. Most persons with MI work, yet symptom severity reduces labor supply among natives especially. Immigrants' labor supply is less affected by MI.

A cost analysis of San Diego County's REACH program for homeless persons

OBJECTIVE

This study examined mental health service utilization and costs associated with the California Assembly Bill 2034 housing-first program for homeless persons in San Diego County: Reaching Out and Engaging to Achieve Consumer Health (REACH).

METHODS

Encounter data were used to identify REACH clients and a control group that was matched by propensity score. Mental health services costs for case management, outpatient services, inpatient and emergency services, criminal justice system services, and total services were summarized for two-year periods before and after clients initiated REACH. Incremental costs of the program were calculated as the difference in cost among clients in the REACH group, from pre- to postintervention, less the difference in cost among those in the control group from pre- to postintervention.

RESULTS

A total of 177 REACH clients and 161 clients in a control group matched by propensity score were identified. Among REACH participants, case management costs increased by $6,403 (p<.001) from pre- to postintervention, inpatient plus emergency services costs declined by $6,103 (p=.034), and costs for mental health services provided by the criminal justice system declined by $570 (p=.020) compared with the control group. The standardized difference-in-difference estimate of the total costs between REACH clients and the control group was not significant.

CONCLUSIONS

Participation in REACH was associated with substantial increases in outpatient services as well as cost offsets in inpatient and emergency services and criminal justice system services. The net cost of services, $417 over two years, was substantially lower than the total cost of services ($20,241).

A cost analysis of San Diego County's REACH program for homeless persons

OBJECTIVE

This study examined mental health service utilization and costs associated with the California Assembly Bill 2034 housing-first program for homeless persons in San Diego County: Reaching Out and Engaging to Achieve Consumer Health (REACH).

METHODS

Encounter data were used to identify REACH clients and a control group that was matched by propensity score. Mental health services costs for case management, outpatient services, inpatient and emergency services, criminal justice system services, and total services were summarized for two-year periods before and after clients initiated REACH. Incremental costs of the program were calculated as the difference in cost among clients in the REACH group, from pre- to postintervention, less the difference in cost among those in the control group from pre- to postintervention.

RESULTS

A total of 177 REACH clients and 161 clients in a control group matched by propensity score were identified. Among REACH participants, case management costs increased by $6,403 (p<.001) from pre- to postintervention, inpatient plus emergency services costs declined by $6,103 (p=.034), and costs for mental health services provided by the criminal justice system declined by $570 (p=.020) compared with the control group. The standardized difference-in-difference estimate of the total costs between REACH clients and the control group was not significant.

CONCLUSIONS

Participation in REACH was associated with substantial increases in outpatient services as well as cost offsets in inpatient and emergency services and criminal justice system services. The net cost of services, $417 over two years, was substantially lower than the total cost of services ($20,241).

Access to public mental health services among older adults with severe mental illness

OBJECTIVE

Limited data are available on how older adults access public mental health systems. This study examines how uninsured or publicly insured older adults with severe mental illness in San Diego County initially accessed the public mental health system, as well as their subsequent use of public mental health services, as compared to younger adults.

METHODS

Data from San Diego County, 2002-2006, were used to examine how older adults initially accessed the public mental health system, and their utilization over the subsequent 90 days. Multivariate regression models were used to control for demographic and clinical characteristics.

RESULTS

Older adults (age 60 +) were more likely to access the public mental health system through the Psychiatric Emergency Response Team (PERT), a combined law-enforcement and psychiatric service that responds to psychiatric related 911 calls. Older adults were also less likely to receive follow-up care. This lower rate of follow-up was due to both the initial site of service--and an associated lower rate of follow-up among PERT clients--as well as a lower rate of follow-up among older adult clients initiating services in other sectors.

CONCLUSIONS

This paper suggests two areas for intervention that would improve access to care for older adults: improving linkages and referrals between PERT and outpatient providers; and additional efforts to retain older adults at outpatient programs.

Adherence to antipsychotics among Latinos and Asians with schizophrenia and limited English proficiency

OBJECTIVES

The authors examined data for 7,784 Latino, Asian, and non-Latino white Medi-Cal beneficiaries with schizophrenia to determine the relationship between patients' preferred language for mental health services--English, Spanish, or an Asian language--and their adherence to treatment with antipsychotic medications.

METHODS

Data reflected 31,560 person-years from 1999 to 2004. Pharmacy records were analyzed to assess medication adherence by use of the medication possession ratio (MPR). Clients were defined as nonadherent (MPR<.5), partially adherent (MPR=.5-<.8), or adherent (MPR=.8-1.1) or as an excess filler of prescriptions (MPR<1.1). Regression models were used to examine adherence, hospitalization, and costs by race-ethnicity and language status.

RESULTS

Latinos with limited English proficiency were more likely than English-proficient Latinos to be medication adherent (41% versus 36%; p<.001) and less likely to be excess fillers (15% versus 20%; p<.001). Asians with limited English proficiency were less likely than English-proficient Asians to be adherent (40% versus 45%; p=.034), more likely to be nonadherent (29% versus 22%; p<.001), and less likely to be excess fillers (13% versus 17%; p=.004). When analyses controlled for adherence and comorbidities, clients with limited English proficiency had lower rates of hospitalization and lower health care costs than English-proficient and white clients.

CONCLUSIONS

Adherence to antipsychotic medications varied by English proficiency among and within ethnic groups. Policies supporting the training of bilingual and multicultural providers from ethnic minority groups and interventions that capitalize on patients' existing social support networks may improve adherence to treatment in linguistically diverse populations.

Evaluation of the first year of a pilot program in community pharmacy: HIV/AIDS medication therapy management for Medi-Cal beneficiaries

BACKGROUND

The advent of combined antiretroviral therapy (ART) has increased treatment effectiveness but created new challenges for patients infected with human immunodeficiency virus (HIV) and for community pharmacists managing patients' drug therapy. The ability of pharmacist-provided medication therapy management (MTM) services to increase medication adherence, improve health outcomes, and reduce overall medical costs has been demonstrated in community pharmacies for chronic diseases such as diabetes and hypertension. However, the effectiveness of pharmacist-provided MTM services in HIV/acquired immune deficiency syndrome (AIDS) has not been well studied. In January 2005, a pilot program to evaluate MTM services for patients with HIV/AIDS began in California, allowing 10 HIV/AIDS specialty pharmacies to receive compensation for the MTM services that they provided to HIV/AIDS patients.

OBJECTIVES

To examine the first year of the HIV/AIDS pharmacy MTM compensation pilot program, which described and compared pilot and nonpilot pharmacies with respect to (a) patient characteristics; (b) intermediate outcomes including type and number of ART medication regimens used, rates of adherence and excess medication fills for ART, use of contraindicated ART regimens, and occurrence of opportunistic infections; and (c) pharmacy and medical costs.

METHODS

This was a cohort study examining 2005 Medi-Cal pharmacy and medical claims data for patients with HIV/AIDS who were served by pilot pharmacies versus other pharmacies. The HIV/AIDS patients were Medi-Cal beneficiaries aged 18 years or older as of January 1, 2005, who were continuously enrolled from January 1, 2004, through December 31, 2005, and diagnosed with HIV/AIDS, identified by receipt of at least 1 ART prescription and at least 1 medical claim with a diagnosis (primary or secondary) of HIV/AIDS (ICD-9-CM code 042.0) during both the index period (the year before pilot program implementation, 2004) and the intervention period (the study year, 2005). The only difference in the inclusion criteria for the 2 cohorts was that the pilot pharmacy patients were required to have filled 50% or more of their antiretroviral prescriptions in 2005 at 1 of the 10 pilot pharmacies. Adherence was defined as a medication possession ratio (MPR) of 80%-120% and excess medication fills as MPR greater than 120%. Comparisons were made between groups using bivariate statistics (Pearson chi-square for categorical variables and t-tests for continuous variables). For comparisons of costs, generalized linear models assuming a gamma distribution and log link function were used; predictor variables for the models included age, gender, race/ethnicity, and dual coverage under Medicare.

RESULTS

A total of 7,018 HIV/AIDS patients in the Medi-Cal population were identified as meeting the study criteria. Of these, 19.3% (n=1,353) were pilot pharmacy patients. The demographic profile of pilot pharmacy patients was similar, but not identical, to that of patients receiving medications at other pharmacies. A larger percentage of pilot pharmacy patients were on protease inhibitor-based ART medication regimens (63.8% vs. 54.8%, P<0.001), remained on a single type of ART therapy throughout the study year (56.8% vs. 34.2%, P<0.001), and were classified as adherent (56.3% vs. 38.1%, P<0.001), compared with other pharmacy patients. Fewer pilot pharmacy patients used contraindicated regimens (11.6% vs. 16.6%, P<0.001) or had excess medication fills (19.7% vs. 44.8%, P<0.001). The rate of opportunistic infections did not differ significantly between groups (28.2% vs. 26.1%, P=0.121). The total mean (standard error) annual health care cost per patient was 10% higher in pilot pharmacies than in other pharmacies ($40,596 [$889] vs. $36,937 [$479], P=0.001); driven by use of (a) medications (primarily non-ART medications) and (b) mental health services. Payment from the California Department of Health Care Services for MTM services averaged $1,014 per pilot pharmacy study patient.

CONCLUSION

Study findings for the first year of the MTM program suggest that the pilot pharmacy patients received more appropriate HIV treatment. The degree to which these differences are affected by selfselection of patients into the pilot pharmacies is unknown. Longer-term outcomes and costs of the pilot program will be examined when data for subsequent years are available.

Trends in use of antipsychotics and mood stabilizers among Medicaid beneficiaries with bipolar disorder, 2001-2004

OBJECTIVE

This study examined longitudinal trends in the use of mood stabilizers and antipsychotics for treatment of bipolar disorder in a large public mental health system and whether trends differed by age, gender, and race-ethnicity.

METHODS

Data were from Medicaid beneficiaries with bipolar disorder receiving services in the San Diego County public mental health system from 2001 to 2004. For each year the proportion of clients receiving any pharmacotherapy and the proportion receiving antipsychotics alone, mood stabilizers alone, or antipsychotics plus mood stabilizers were determined. Pharmacotherapy use was examined by age, gender, and race-ethnicity.

RESULTS

A total of 1,473 clients were identified who were continuously enrolled in Medicaid during the four years. Seventy-five percent received mood stabilizers or antipsychotics. Of this group, 33% received antipsychotics alone, 23% mood stabilizers alone, and 44% both antipsychotics and mood stabilizers. The percentage receiving mood stabilizers or antipsychotics increased significantly, from 71% in 2001 to 77% in 2004, primarily because of increased use among women. Use of mood stabilizers alone declined from 25% to 20%, and use of antipsychotics alone increased from 32% to 36%. African Americans and Latinos were less likely than non-Latino whites to receive mood stabilizers or antipsychotics; this pattern was stable over time.

CONCLUSIONS

Antipsychotics were prescribed for a larger percentage of clients than mood stabilizers. Persons from ethnic minority groups were less likely to receive either medication type. Research is needed to examine factors affecting pharmacotherapy in bipolar disorder and mechanisms underlying racial-ethnic disparities in pharmacotherapy, including their persistence over time.

Improving treatment of depression among Latinos with diabetes using project Dulce and IMPACT

OBJECTIVE

To assess the feasibility and cost of integrating diabetes and depression care management in three community clinics serving a low-income and predominantly Spanish-speaking Latino population.

RESEARCH DESIGN AND METHODS

We screened diabetes patients for depression, and for those with depressive symptoms, we provided depression care management. We assessed changes in depressive symptoms using the Patient Health Questionnaire-9 (PHQ-9), diabetes self-care activities (nutrition, exercise, and medication adherence), and costs.

RESULTS

Thirty-three percent of patients with diabetes had symptoms of major depression. Among 99 patients completing the study, PHQ-9 scores declined by an average of 7.5 points from 14.8 to 7.3 (P < 0.001). Clients averaged 6.7 visits with the care manager during the study period. Costs of depression care management were estimated to be $512 per participant.

CONCLUSIONS

Adding a depression care manager to an existing diabetes management team was effective at reducing depressive symptoms at a reasonable cost.
