Can a Home-Based Collaborative Care Model Reduce Health Services Utilization for Older Medicaid Beneficiaries Living with Depression and Co-occurring Chronic Conditions? A Quasi-experimental Study.

Depression remains a major public health issue for older adults, increasing risk of costly health services utilization. While home-based collaborative care models (CCM) like PEARLS have been shown to effectively treat depression in low-income older adults living with multiple chronic conditions, their economic impact is unclear. We conducted a quasi-experimental study to estimate PEARLS effect on health service utilization among low-income older adults. Our secondary data analysis merged de-identified PEARLS program data (N = 1106), home and community-based services (HCBS) administrative data (N = 16,096), and Medicaid claims and encounters data (N = 164) from 2011 to 2016 in Washington State. We used nearest neighbor propensity matching to create a comparison group of social service recipients similar to PEARLS participants on key determinants of utilization guided by Andersen's Model. Primary outcomes were inpatient hospitalizations, emergency room (ER) visits, and nursing home days; secondary outcomes were long-term supports and services (LTSS), mortality, depression and health. We used an event study difference-in-difference (DID) approach to compare outcomes. Our final dataset included 164 older adults (74% female, 39% people of color, mean PHQ-9 12.2). One-year post-enrollment, PEARLS participants had statistically significant improvements in inpatient hospitalizations (69 fewer hospitalizations per 1000 member months, p = 0.02) and 37 fewer nursing home days (p < 0.01) than comparison group participants; there were no significant improvements in ER visits. PEARLS participants also experienced lower mortality. This study shows the potential value of home-based CCM for participants, organizations and policymakers. Future research is needed to examine potential cost savings.

First-Year Economic and Quality of Life Effects of the RAINBOW Intervention to Treat Comorbid Obesity and Depression.

OBJECTIVE: Obesity and depression are prevalent and often co-occurring conditions in the United States. The Research Aimed at Improving Both Mood and Weight (RAINBOW) randomized trial demonstrated the effectiveness of an integrated intervention for adults with both conditions. Characterizing the intervention's economic effects is important for broader dissemination and implementation. METHODS: This study evaluated the cost (2018 US dollars) and health-related quality of life (HRQoL) impacts during RAINBOW's first year, comparing intervention (n = 204) and usual-care groups (n = 205). Outcomes included intervention delivery costs, differential changes in antidepressant medication spending compared with the pretrial year, differential changes in medical services spending compared with the pretrial year, and HRQoL changes from baseline using Euroqol-5D US utility weights. RESULTS: RAINBOW's 1-year delivery cost per person was $2,251. Compared with usual care, annual antidepressant medication days increased more (38 days [95% CI: 4 to 72]; P = 0.027). Annual antidepressant medication spending had a larger, nonsignificant increase ($89 [95% CI: -$20 to $197]; P = 0.109). Annual spending on medical care services had a smaller, nonsignificant decrease (-$54 [95% CI: -$832 to $941]; P = 0.905). HRQoL had a nonsignificant increase (0.011 [95% CI: -0.025 to 0.047]; P = 0.546). CONCLUSIONS: The RAINBOW intervention's economic value will depend on how its 1-year improvements in obesity and depression translate into long-term reduced morbidity, delayed mortality, or averted costs.

Integrating Primary Care Into Community Mental Health Centers: Impact on Utilization and Costs of Health Care.

OBJECTIVE: This evaluation was designed to assess the impact of providing integrated primary and mental health care on utilization and costs for outpatient medical, inpatient hospital, and emergency department treatment among persons with serious mental illness. METHODS: Two safety-net, community mental health centers that received a Substance Abuse and Mental Health Services Administration Primary and Behavioral Health Care Integration (PBHCI) grant were the focus of this study. Clinic 1 had a ten-year history of providing integrated services whereas clinic 2 began integrated services with the PBHCI grant. Difference-in-differences (DID) analyses were used to compare individuals enrolled in the PBHCI programs (N=373, clinic 1; N=389, clinic 2) with propensity score-matched comparison groups of equal size at each site by using data obtained from medical records. RESULTS: Relative to the comparison groups, a higher proportion of PBHCI clients used outpatient medical services at both sites following program enrollment (p<.003, clinic 1; p<.001, clinic 2). At clinic 1, PBHCI was also associated with a reduction in the proportion of clients with an inpatient hospital admission (p=.04) and a trend for a reduction in inpatient hospital costs per member per month of $217.68 (p=.06). Hospital-related cost savings were not observed for PBHCI clients at clinic 2 nor were there significant differences between emergency department use or costs for PBHCI and comparison groups at either clinic. CONCLUSIONS: Investments in PBHCI can improve access to outpatient medical care for persons with severe mental illness and may also curb hospitalizations and associated costs in more established programs.

Research aimed at improving both mood and weight (RAINBOW) in primary care: A type 1 hybrid design randomized controlled trial.

Effective interventions targeting comorbid obesity and depression are critical given the increasing prevalence and worsened outcomes for patients with both conditions. RAINBOW is a type 1 hybrid design randomized controlled trial. The objective is to evaluate the clinical and cost effectiveness and implementation potential of an integrated, technology-enhanced, collaborative care model for treating comorbid obesity and depression in primary care. Obese and depressed adults (n = 404) will be randomized to usual care enhanced with the provision of a pedometer and information about the health system's services for mood or weight management (control) or with the Integrated Coaching for Better Mood and Weight (I-CARE) program (intervention). The 12-month I-CARE program synergistically integrates two proven behavioral interventions: problem-solving therapy with as-needed intensification of pharmacotherapy for depression (PEARLS) and standardized behavioral treatment for obesity (Group Lifestyle Balance(™)). It utilizes traditional (e.g., office visits and phone consults) and emerging care delivery modalities (e.g., patient web portal and mobile applications). Follow-up assessments will occur at 6, 12, 18, and 24 months. We hypothesize that compared with controls, I-CARE participants will have greater improvements in weight and depression severity measured by the 20-item Depression Symptom Checklist at 12 months, which will be sustained at 24 months. We will also assess I-CARE's cost-effectiveness and use mixed methods to examine its potential for reach, adoption, implementation, and maintenance. This study offers the potential to change how obese and depressed adults are treated-through a new model of accessible and integrative lifestyle medicine and mental health expertise-in primary care.

It Could Be a Pearl to You: Exploring Recruitment and Retention of the Program to Encourage Active, Rewarding Lives (PEARLS) With Hard-to-Reach Populations.

PURPOSE OF THE STUDY: We partnered with 3 social service organizations to identify hard-to-reach populations, barriers to reach, and strategies for improving recruitment and retention for Program to Encourage Active, Rewarding Lives (PEARLS), a home-based depression-care management program for elders. DESIGN AND METHODS: We conducted semistructured interviews with staff and former PEARLS participants. All interviews were transcribed verbatim and thematically analyzed. RESULTS: Veterans, African Americans, Filipino men, other immigrants and English-language learners, old-older adults, rural communities, and people with limited education were identified as hard to reach. The themes of trust, cultural appropriateness, meet them where they are, and framing and reframing, cut across barriers to participation in PEARLS and approaches for overcoming these barriers. IMPLICATIONS: Research findings will be used to inform technical assistance activities with PEARLS providers, changes to PEARLS program and training materials, and future PEARLS research activities.

Implementing evidence-based psychotherapies in settings serving older adults: challenges and solutions.

This Open Forum addresses challenges--insurance limitations, staff and setting limitations, and training and sustainability issues--in the implementation of psychotherapy interventions in settings serving older adults and provides solutions for ensuring that they have access to effective mental health services. There is considerable movement toward developing the geriatric mental health workforce, and it is important that these efforts include a discussion of implementation issues with regard to evidence-based psychotherapies as they are provided in services for aging populations.

Implementation of an evidence-based depression care management program (PEARLS): perspectives from staff and former clients.

INTRODUCTION: Although researchers develop evidence-based programs for public health practice, rates of adoption and implementation are often low. This qualitative study aimed to better understand implementation of the Program to Encourage Active, Rewarding Lives for Seniors (PEARLS), a depression care management program at a Seattle-King County area agency on aging. METHODS: We used stratified, purposive sampling in 2008 to identify 38 PEARLS clients and agency staff for participation. In 9 focus groups and 1 one-on-one interview, we asked participants to identify benefits and negative consequences of PEARLS, facilitators of and barriers to program implementation, and strategies for overcoming the barriers. Two independent researchers used thematic analysis to categorize data into key themes and subthemes. RESULTS: PEARLS benefits clients by decreasing depression symptoms and addressing other concerns, such as health problems. For staff, PEARLS provides "another set of eyes" and is a comprehensive program to help them meet clients' mental health needs. Barriers included issues with implementation process (eg, lack of communication) and the perception that eligibility criteria were more rigid than those of other agency programs. Recommended solutions included changing eligibility criteria, providing additional staff training, increasing communication, and clarifying referral procedures, roles, and responsibilities. CONCLUSION: Barriers to PEARLS delivery discourage referrals to what is generally viewed as a beneficial program. Implementing participants' strategies for overcoming these barriers can enhance delivery of PEARLS to a greater number of older adults and help them improve their depression symptoms.

Assessment and treatment of nursing home residents with depression or behavioral symptoms associated with dementia: a review of the literature.

Depression and the behavioral symptoms associated with dementia remain two of the most significant mental health issues for nursing home residents. The extensive literature on these conditions in nursing homes was reviewed to provide an expert panel with an evidence base for making recommendations on the assessment and treatment of these problems. Numerous assessment instruments have been validated for depression and for behavioral symptoms. The Minimum Data Set, as routinely collected, appears to be of limited utility as a screening instrument for depression but is useful for assessing some behavioral symptoms. Laboratory evaluations are often recommended, but no systematic study of the outcomes of these evaluations could be found. Studies of nonpharmacological interventions out-number those of pharmacological interventions, and randomized, controlled trials document the efficacy of many interventions. Antidepressants are effective for major depression, but data for minor depressive syndromes are limited. Recreational activities are effective for major and minor depression categories. Neither pharmacological nor nonpharmacological interventions totally eliminate behavioral symptoms, but both types of interventions decrease the severity of symptoms. In the absence of comparison studies, it is unclear whether one approach is more effective than another. Despite federal regulations limiting their use, antipsychotics are effective and remain the most studied medications for treating behavioral symptoms, whereas benzodiazepines and antidepressants have less support. Structured activities are effective, but training interventions for behavioral symptoms had limited results. There are sufficient data to formulate an evidenced-based approach to treatment of depression and behavioral symptoms, but more research is needed to prioritize treatments.
