Background

Depression collaborative care implementation using community engagement and planning (CEP) across programs improves 6-month client outcomes in minority communities, compared with technical assistance to individual programs (resources for services [RS]). However, 12-month outcomes are unknown.

Objective

To compare effects of CEP and RS on mental health-related quality of life (MHRQL) and use of services among depressed clients at 12 months.

Design

Matched health and community programs (n = 93) in 2 communities randomly assigned to receive CEP or RS. (ClinicalTrials.gov: NCT01699789).

Measurements

Self-reported MHRQL and services use at baseline, 6 months, and 12 months.

Setting

Los Angeles, California.

Patients

1018 adults with depressive symptoms (8-item Patient Health Questionnaire score ≥10), 88% of whom were an ethnic minority.

Intervention

CEP and RS to implement depression collaborative care.

Measurements

The primary outcome was poor MHRQL (12-item mental health composite score ≤40) at baseline, 6 months, and 12 months; the secondary outcome was use of services at 12 months.

Results

At 6 months, the finding that CEP outperformed RS to reduce poor MHRQL was significant but sensitive to underlying statistical assumptions. At 12 months, some analyses suggested that CEP was advantageous to MHRQL, whereas others did not confirm a significant difference favoring CEP. The finding that CEP reduced behavioral health hospitalizations at 6 months was less evident at 12 months and was sensitive to underlying statistical assumptions. Other services use did not significantly differ between interventions at 12 months.

Limitation

Data are self-reported, and findings are sensitive to modeling assumptions.

Conclusion

In contrast to 6-month results, no consistent effects of CEP on reducing the likelihood of poor MHRQL and behavioral health hospitalizations were found at 12 months. Still, given the needs of underresourced communities, the favorable profile of CEP, and the lack of evidence-based alternatives, CEP remains a viable strategy for policymakers and communities to consider.

Primary funding source

National Institute of Mental Health, Robert Wood Johnson Foundation, California Community Foundation, National Library of Medicine, and National Institutes of Health/National Center for Advancing Translational Science for the UCLA Clinical and Translational Science Institute.

Objective

Community-based participatory research is recommended for research on health disparities and to improve uptake of clinical research findings. We describe the development of a multicenter consortium designed to support a community agency-academic partner infrastructure to support community-based, health-services research on multiple sources of health and healthcare disparities in local communities.

Design

We describe the development of the Los Angeles Community Health Improvement Collaborative (CHIC).

Results

The CHIC partners examined the research capacity and health priorities of its partners and developed a research agenda focused on four tracer conditions (depression, violence, diabetes, and obesity) and four areas for development of research capacity: public participation in all phases of research; understanding community and organizational context for clinical services interventions; practical clinical services trial methods; and advancing health information technology for clinical services research. The partners pooled resources to develop these areas for the tracer conditions.

Conclusions

The challenges of a participatory approach to community-based clinical services research go beyond the significant methodologic and operational issues for specific projects and include building a sustainable capacity for research, community programs, and partnership across diverse communities and stakeholder organizations even when funding sources are not fully aligned with these goals.

Objective

To compare community engagement and planning (CEP) for coalition support to implement depression quality improvement (QI) to resources for services (RS) effects on service-use costs over a 12-month period.

Design

Matched health and community programs (N=93) were cluster-randomized within communities to CEP or RS.

Setting

Two Los Angeles communities.

Participants

Adults (N=1,013) with depressive symptoms (Patient Health Questionnaire (PHQ-8) ≥10); 85% African American and Latino.

Interventions

CEP and RS to support programs in depression QI.

Main outcome measures

Intervention training and service-use costs over 12 months.

Results

CEP planning and training costs were almost 3 times higher than RS, largely due to greater CEP provider training participation vs RS, with no significant differences in 12-month service-use costs.

Conclusions

Compared with RS, CEP had higher planning and training costs with similar service-use costs.

Objective

The effectiveness of community coalition building and program technical assistance was compared in implementation of collaborative care for depression among health care and community sector clients.

Methods

In under-resourced communities, within 93 programs randomly assigned to coalition building (Community Engagement and Planning) or program technical assistance (Resources for Services) models, 1,018 clients completed surveys at baseline and at six, 12, or 36 months. Regression analysis was used to estimate intervention effects and intervention-by-sector interaction effects on depression, mental health-related quality of life, and community-prioritized outcomes and on services use.

Results

For outcomes, there were few significant intervention-by-sector interactions, and stratified findings suggested benefits of coalition building in both sectors. For services use, at 36 months, increases were found for coalition building in primary care visits, self-help visits, and appropriate treatment for community clients and in community-based services use for health care clients.

Conclusions

Relative to program technical assistance, community coalition building benefited clients across sectors and shifted long-term utilization across sectors.

Objective

Community Partners in Care, a community-partnered, cluster-randomized trial with depressed clients from 93 Los Angeles health and community programs, examined the added value of a community coalition approach (Community Engagement and Planning [CEP]) versus individual program technical assistance (Resources for Services [RS]) for implementing depression quality improvement in underserved communities. CEP was more effective than RS in improving mental health-related quality of life, reducing behavioral health hospitalizations, and shifting services toward community-based programs at six months. At 12 months, continued evidence of improvement was found. This study examined three-year outcomes.

Methods

Among 1,004 participants with depression who were eligible for three-year follow-up, 600 participants from 89 programs completed surveys. Multiple regression analyses estimated intervention effects on poor mental health-related quality of life and depression, physical health-related quality of life, behavioral health hospital nights, and use of services.

Results

At three years, no differences were found in the effects of CEP versus RS on depression or mental health-related quality of life, but CEP had modest effects in improving physical health-related quality of life and reducing behavioral health hospital nights, and CEP participants had more social- and community-sector depression visits and greater use of mood stabilizers. Sensitivity analyses with longitudinal modeling reproduced these findings but found no significant differences between groups in change from baseline to three years.

Conclusions

At three years, CEP and RS did not have differential effects on primary mental health outcomes, but CEP participants had modest improvements in physical health and fewer behavioral health hospital nights.
