Collaborative care management of major depression among low-income, predominantly Hispanic subjects with diabetes: a randomized controlled trial.

OBJECTIVE To determine whether evidence-based socioculturally adapted collaborative depression care improves receipt of depression care and depression and diabetes outcomes in low-income Hispanic subjects. RESEARCH DESIGN AND METHODS This was a randomized controlled trial of 387 diabetic patients (96.5% Hispanic) with clinically significant depression recruited from two public safety-net clinics from August 2005 to July 2007 and followed over 18 months. Intervention (INT group) included problem-solving therapy and/or antidepressant medication based on a stepped-care algorithm; first-line treatment choice; telephone treatment response, adherence, and relapse prevention follow-up over 12 months; plus systems navigation assistance. Enhanced usual care (EUC group) included standard clinic care plus patient receipt of depression educational pamphlets and a community resource list. RESULTS INT patients had significantly greater depression improvement (≥50% reduction in Symptom Checklist-20 depression score from baseline; 57, 62, and 62% vs. the EUC groups 36, 42, and 44% at 6, 12, and 18 months, respectively; odds ratio 2.46–2.57; P < 0.001). Mixed-effects linear regression models showed a significant study group–by–time interaction over 18 months in diabetes symptoms; anxiety; Medical Outcomes Study Short-Form Health Survey (SF-12) emotional, physical, and pain-related functioning; Sheehan disability; financial situation; and number of social stressors (P = 0.04 for disability and SF-12 physical functioning, P < 0.001 for all others) but no study group–by–time interaction in A1C, diabetes complications, self-care management, or BMI. CONCLUSIONS Socioculturally adapted collaborative depression care improved depression, functional outcomes, and receipt of depression treatment in predominantly Hispanic patients in safety-net clinics.

Cost-Effectiveness Analysis of Collaborative Care Management of Major Depression among Low-Income, Predominantly Hispanics with Diabetes

OBJECTIVE To evaluate the cost-effectiveness of a socioculturally adapted collaborative depression care program among low-income Hispanics with diabetes. RESEARCH DESIGN AND METHODS A randomized controlled trial of 387 patients with diabetes (96.5% Hispanic) with clinically significant depression followed over 18 months evaluated the cost-effectiveness of the Multifaceted Diabetes and Depression Program aimed at increasing patient exposure to evidence-based depression psychotherapy and/or pharmacotherapy in two public safety net clinics. Patient medical care costs and utilization were captured from Los Angeles County Department of Health Services claims records. Patient-reported outcomes included Short-Form Health Survey-12 and Patient Health Questionnaire-9-calculated depression-free days. RESULTS Intervention patients had significantly greater Short-Form Health Survey-12 utility improvement from baseline compared with controls over the 18-month evaluation period (4.8%; P < 0.001) and a corresponding significant improvement in depression-free days (43.0; P < 0.001). Medical cost differences were not statistically significant in ordinary least squares and log-transformed cost regressions. The average costs of the Multifaceted Diabetes and Depression Program study intervention were

Randomized, Controlled Trial of an Intervention to Enable Stroke Survivors Throughout the Los Angeles County Safety Net to “Stay With the Guidelines”

OBJECTIVE The aim of this study was to determine sustained effectiveness in reducing depression symptoms and improving depression care 1 year following intervention completion. METHOD Of 387 low-income, predominantly Hispanic diabetes patients with major depression symptoms randomized to 12-month socioculturally adapted collaborative care (psychotherapy and/or antidepressants, telephone symptom monitoring/relapse prevention) or enhanced usual care, 264 patients completed 2-year follow-up. Depression symptoms (Symptom Checklist-20 [SCL-20], Patient Health Questionnaire-9 [PHQ-9]), treatment receipt, diabetes symptoms and quality of life were assessed 24 months postenrollment using intent-to-treat analyses. RESULTS At 24 months, more intervention patients received ongoing antidepressant treatment (38% vs. 25%, χ(2)=5.11, df=1, P=.02); sustained depression symptom improvement [SCL-20 <0.5 (adjusted odds ratio=2.06, 95% confidence interval=1.09-3.90, P=.03), SCL-20 score (adjusted mean difference -0.22, P=.001) and PHQ-9 ≥50% reduction (adjusted odds ratio=1.87, 95% confidence interval =1.05-3.32, P=.03)]. Over 2 years, improved effects were found in significant study group by time interaction for Short Form-12 mental health, Sheehan Disability Scale (SDS) functional impairment, diabetes symptoms, anxiety and socioeconomic stressors (P=.02 for SDS; P<.0001 for all others); however, group differences narrowed over time and were no longer significant at 24 months. CONCLUSIONS Socioculturally tailored collaborative care that included maintenance antidepressant medication, ongoing symptom monitoring and behavioral activation relapse prevention was associated with depression improvement over 24 months for predominantly Hispanic patients in primary safety net care.

Asthma control and future asthma-related morbidity in inner-city asthmatic children

BACKGROUND To improve medication adherence in cardiac patients, in partnership with a safety-net provider, this research team developed and evaluated a low-literacy medication education tool. METHODS Using principles of community-based participatory research, the team developed a prototype of a low-literacy hospital discharge medication education tool, customizable for each patient, featuring instruction-specific icons and pictures of pills. In 2007, a randomized controlled clinical trial was performed, testing the tools effect on posthospitalization self-reported medication adherence and knowledge, 2 weeks postdischarge in English- and Spanish-speaking safety-net inpatients. To validate the self-report measure, 4 weeks postdischarge, investigators collected self-reports of the number of pills remaining for each medication in a subsample of participants. Nurses rated tool acceptability. RESULTS Among the 166/210 eligible participants (79%) completing the Week-2 interview, self-reported medication adherence was 70% (95% CI=62%, 79%) in intervention participants and 78% (95% CI=72%, 84%) in controls (p=0.13). Among the 85 participants (31%) completing the Week-4 interview, self-reported pill counts indicated high adherence (greater than 90%) and did not differ between study arms. Self-reported adherence was correlated with self-reported pill count in intervention participants (R=0.5, p=0.004) but not in controls (R=0.07, p=0.65). There were no differences by study arm in medication knowledge. The nurses rated the tool as highly acceptable. CONCLUSIONS Although the evaluation did not demonstrate the tool to have any effect on self-reported medication adherence, patients who received the schedule self-reported their medication adherence more accurately, perhaps indicating improved understanding of their medication regimen and awareness of non-adherence.

Patient-centered Technological Assessment and Monitoring of Depression for Low-Income Patients

Health disparities in minority populations are well recognized. Hispanics and Latinos constitute the largest ethnic minority group in the United States; a significant proportion receives their care via a safety net. The prevalence of diabetes mellitus and comorbid depression is high among this group, but the uptake of evidence-based collaborative depression care management has been suboptimal. The study design and baseline characteristics of the enrolled sample in the Diabetes-Depression Care-management Adoption Trial (DCAT) establishes a quasi-experimental comparative effectiveness research clinical trial aimed at accelerating the adoption of collaborative depression care in safety net clinics. The study was conducted in collaboration with the Los Angeles County Department of Health Services at eight county-operated clinics. DCAT has enrolled 1406 low-income, predominantly Hispanic/Latino patients with diabetes to test a translational model of depression care management. This three-group study compares usual care with a collaborative care team support model and a technology-facilitated depression care model that provides automated telephonic depression screening and monitoring tailored to patient conditions and preferences. Call results are integrated into a diabetes disease management registry that delivers provider notifications, generates tasks, and issues critical alerts. All subjects receive comprehensive assessments at baseline, 6, 12, and 18 months by independent English-Spanish bilingual interviewers. Study outcomes include depression outcomes, treatment adherence, satisfaction, acceptance of assessment and monitoring technology, social and economic stress reduction, diabetes self-care management, health care utilization, and care management model cost and cost-effectiveness comparisons. DCATs goal is to optimize depression screening, treatment, follow-up, outcomes, and cost savings to reduce health disparities.

Depressive Symptom Deterioration among Predominantly Hispanic Diabetes Patients in Safety Net Care

Background— Stroke is the leading cause of adult disability. Inpatient programs optimize secondary stroke prevention care at the time of hospital discharge, but such care may not be continued after hospital discharge. Methods— To improve the delivery of secondary stroke preventive services after hospital discharge, we have designed a chronic care model–based program called SUSTAIN (Systemic Use of STroke Averting INterventions). This care intervention includes group clinics, self-management support, report cards, decision support through care guides and protocols, and coordination of ongoing care. The first specific aim is to test, in a randomized, controlled trial, whether SUSTAIN improves blood pressure control among an analytic sample of 268 patients with a recent stroke or transient ischemic attack discharged from 4 Los Angeles County public hospitals. Secondary outcomes consist of control of other stroke risk factors, lifestyle habits, medication adherence, patient perceptions of care quality, functional status, and quality of life. A second specific aim is to conduct a cost analysis of SUSTAIN from the perspective of the Los Angeles County Department of Health Services by using direct costs of the intervention, cost equivalents of associated utilization of county system resources, and cost equivalents of the observed and predicted averted vascular events. Conclusions— If SUSTAIN is effective, we will have the expertise and findings to advocate for its continued support at Los Angeles County hospitals and to disseminate the SUSTAIN program to other settings serving indigent, minority populations.

Validation of a single survey that can be used for case identification and assessment of asthma control: the Breathmobile Program.

BACKGROUND Asthma guidelines recommend routine evaluation of asthma control, which includes measurements of impairment and risk. It is unclear whether rigorous asthma control changes risk of asthma morbidity. OBJECTIVE To examine whether the degree of asthma control in inner-city asthmatic children results in differential risk reduction of future asthma-related morbidity. METHODS This retrospective observational study examines 960 inner-city children with asthma who were highly engaged in an asthma-specific disease management program for a minimum of 2 years. Degree of asthma control was determined during the first year of enrollment and was categorized as well controlled (> or = 80% of visits in control), moderately controlled (50%-79% of visits in control), or difficult to control (< 50% of visits in control). Risk and probability of asthma-related morbidity at each visit were determined during the second year of enrollment and included self-reported asthma exacerbations requiring systemic corticosteroid rescue and emergency department visits or hospitalizations. RESULTS Increasing the degree of asthma control measured during the first year of enrollment led to statistically significant incremental reductions in risk of acute asthma exacerbations and emergency department visits or hospitalizations during the second year of enrollment. CONCLUSIONS Achieving and maintaining asthma control in inner-city children with asthma results in significant reductions in asthma-related morbidity. Systematic assessments of asthma control may be useful for predicting future risk in children with asthma.
