Long term outcomes from the IMPACT randomised trial for depressed elderly patients in primary care

Abstract Objective To determine the long term effectiveness of collaborative care management for depression in late life. Design Two arm, randomised, clinical trial; intervention one year and follow-up two years. Setting 18 primary care clinics in eight US healthcare organisations. Patients 1801 primary care patients aged 60 and older with major depression, dysthymia, or both. Intervention Patients were randomly assigned to a 12 month collaborative care intervention (IMPACT) or usual care for depression. Teams including a depression care manager, primary care doctor, and psychiatrist offered education, behavioural activation, antidepressants, a brief, behaviour based psychotherapy (problem solving treatment), and relapse prevention geared to each patients needs and preferences. Main outcome measures Interviewers, blinded to treatment assignment, conducted interviews in person at baseline and by telephone at each subsequent follow up. They measured depression (SCL-20), overall functional impairment and quality of life (SF-12), physical functioning (PCS-12), depression treatment, and satisfaction with care. Results IMPACT patients fared significantly (P < 0.05) better than controls regarding continuation of antidepressant treatment, depressive symptoms, remission of depression, physical functioning, quality of life, self efficacy, and satisfaction with care at 18 and 24 months. One year after IMPACT resources were withdrawn, a significant difference in SCL-20 scores (0.23, P < 0.0001) favouring IMPACT patients remained. Conclusions Tailored collaborative care actively engages older adults in treatment for depression and delivers substantial and persistent long term benefits. Benefits include less depression, better physical functioning, and an enhanced quality of life. The IMPACT model may show the way to less depression and healthier lives for older adults.

Depression Treatment in a Sample of 1,801 Depressed Older Adults in Primary Care

OBJECTIVES: To examine rates and predictors of lifetime and recent depression treatment in a sample of 1,801 depressed older primary care patients

Improving depression care for older, minority patients in primary care

Objective:Few older minorities receive adequate treatment of depression in primary care. This study examines whether a collaborative care model for depression in primary care is as effective in older minorities as it is in nonminority elderly patients in improving depression treatment and outcomes. Study Design:A multisite randomized clinical trial of 1801 older adults comparing collaborative care for depression with treatment as usual in primary care. Twelve percent of the sample were black (n = 222), 8% were Latino (n = 138), and 3% (n = 53) were from other minority groups. We compared the 3 largest ethnic groups (non-Latino white, black, and Latino) on depression severity, quality of life, and mental health service use at baseline, 3, 6, and 12 months after randomization to collaborative care or usual care. Principal Findings:Compared with care as usual, collaborative care significantly improved rates and outcomes of depression care in older adults from ethnic minority groups and in older whites. At 12 months, intervention patients from ethnic minorities (blacks and Latinos) had significantly greater rates of depression care for both antidepressant medication and psychotherapy, lower depression severity, and less health-related functional impairment than usual care participants (64%, 95% confidence interval [CI] 55–72 versus 45%, CI 36–55, P = 0.003 for antidepressant medication; 37%, CI 28–47 versus 13%, CI 6–19, P = 0.002 for psychotherapy; mean = 0.9, CI 0.8–1.1 versus mean = 1.4, CI 1.3–1.5, P < 0.001 for depression severity, range 0–4; mean = 3.7, CI 3.2–4.1, versus mean = 4.7, CI 4.3–5.1, P < 0.0001 for functional impairment, range 0–10). Conclusions:Collaborative Care is significantly more effective than usual care for depressed older adults, regardless of their ethnicity. Intervention effects in ethnic minority participants were similar to those observed in whites.

Stigma and depression among primary care patients

We assessed stigma affecting employment, health insurance, and friendships in 1,187 depressed patients from 46 U.S. primary care clinics. We compared stigma associated with depression, HIV, diabetes, and hypertension. Finally, we examined the association of depression-related stigma with health services use and unmet need for mental health care during a 6-month follow-up. We found that 67% of depressed primary care patients expected depression related stigma to have a negative effect on employment, 59% on health insurance, and 24% on friendships. Stigma associated with depression was greater than for hypertension or diabetes but not HIV. Younger men reported less stigma affecting employment. Women had more employment-related stigma but this was somewhat mitigated by social support. Other factors associated with stigma included ethnicity (associated with health insurance stigma) and number of chronic medical conditions (associated with health insurance and friendship related stigma). Stigma was not associated with service use, but individuals with stigma concerns related to friendships reported greater unmet mental health care needs. In summary, stigma was common in depressed primary care patients and related to age, gender, ethnicity, social support and chronic medical conditions. The relationship between stigma and service use deserves further study in diverse settings and populations.

Reducing Suicidal Ideation in Depressed Older Primary Care Patients

OBJECTIVES: To determine the effect of a primary care–based collaborative care program for depression on suicidal ideation in older adults.

Can Quality Improvement Programs for Depression in Primary Care Address Patient Preferences for Treatment

Background.Depression is common in primary care, but rates of adequate care are low. Little is known about the role of patient treatment preferences in encouraging entry into care. Objectives.To examine whether a primary care based depression quality improvement (QI) intervention designed to accommodate patient and provider treatment choice increases the likelihood that patients enter depression treatment and receive preferred treatment. Methods.In 46 primary care clinics, patients with current depressive symptoms and either lifetime or current depressive disorder were identified through screening. Treatment preferences, patient characteristics, and use of depression treatments were assessed at baseline and 6 months by patient self-report. Matched clinics were randomized to usual care (UC) or 1 of 2 QI interventions. Data were analyzed using logistic regression models. Results.For patients not in care at baseline, the QI interventions increased rates of entry into depression treatment compared with usual care (adjusted percentage: 50.0% ± 5.3 and 33.0% ± 4.9 for interventions vs. 15.9% ± 3.6 for usual care; F = 12.973, P <0.0001). Patients in intervention clinics were more likely to get treatments they preferred compared with those in usual care (adjusted percentage: 54.2% ± 3.3 and 50.7% ± 3.1 for interventions vs. 40.5% ± 3.1 for usual care; F = 6.034, P <0.003); however, in all clinics less than half of patients preferring counseling reported receiving it. Conclusions.QI interventions that support patient choice can improve the likelihood of patients receiving preferred treatments. Patient treatment preference appears to be related to likelihood of entering depression treatment, and patients preferring counseling may require additional interventions to enhance entry into treatment.

Quality of Publicly-Funded Outpatient Specialty Mental Health Care for Common Childhood Psychiatric Disorders in California

OBJECTIVE To describe the documented adherence to quality indicators for the outpatient care of attention-deficit/hyperactivity disorder, conduct disorder, and major depression for children in public mental health clinics and to explore how adherence varies by child and clinic characteristics. METHOD A statewide, longitudinal cohort study of 813 children ages 6.0-16.9 years with at least 3 months of outpatient care, drawn from 4,958 patients in 62 mental health clinics in California from August 1, 1998, through May 31, 1999. The main outcome was documented adherence to quality indicators based on scientific evidence and clinical judgment, assessed by explicit medical record review. RESULTS Relatively high adherence was recorded for clinical assessment (78%-95%), but documented adherence to quality indicators related to service linkage, parental involvement, use of evidence-based psychosocial treatment, and patient protection were moderate to poor (74.1%-8.0%). For children prescribed psychotropic medication, 28.3% of the records documented monitoring of at least one clinically indicated vital sign or laboratory study. Documented adherence to quality indicators varied little by child demographics or clinic factors. CONCLUSION Efforts to improve care should be directed broadly across clinics, with documentation of safe practices, particularly for children prescribed psychotropic medication, being of highest priority.

Impact of Comorbid Panic and Posttraumatic Stress Disorder on Outcomes of Collaborative Care for Late-Life Depression in Primary Care

OBJECTIVE Comorbid anxiety disorders may result in worse depression treatment outcomes. The authors evaluated the effect of comorbid panic disorder and posttraumatic stress disorder (PTSD) on response to a collaborative-care intervention for late-life depression in primary care. METHODS A total of 1,801 older adults with depression were randomized to a collaborative-care depression treatment model versus usual care and assessed at baseline, 3, 6, and 12 months, comparing differences among participants with comorbid panic disorder (N=262) and PTSD (N=191) and those without such comorbid anxiety disorders. RESULTS At baseline, patients with comorbid anxiety reported higher levels of psychiatric and medical illness, greater functional impairment, and lower quality of life. Participants without comorbid anxiety who received collaborative care had early and lasting improvements in depression compared with those in usual care. Participants with comorbid panic disorder showed similar outcomes, whereas those with comorbid PTSD showed a more delayed response, requiring 12 months of intervention to show a significant effect. At 12 months, however, outcomes were comparable. Interactions of intervention status by comorbid PTSD or panic disorder were not statistically significant, suggesting that the collaborative-care model performed significantly better than usual care in depressed older adults both with and without comorbid anxiety. CONCLUSIONS Collaborative care is more effective than usual care for depressed older adults with and without comorbid panic disorder and PTSD, although a sustained treatment response was slower to emerge for participants with PTSD. Intensive and prolonged follow-up may be needed for depressed older adults with comorbid PTSD.

An Emergency Department Intervention for Linking Pediatric Suicidal Patients to Follow-Up Mental Health Treatment

OBJECTIVE Suicide is the third leading cause of death among adolescents. Many suicidal youths treated in emergency departments do not receive follow-up treatment as advocated by the National Strategy for Suicide Prevention. Two strategies for improving rates of follow-up treatment were compared. METHODS In a randomized controlled trial, suicidal youths at two emergency departments (N=181; ages ten to 18) were individually assigned between April 2003 and August 2005 to one of two conditions: an enhanced mental health intervention involving a family-based cognitive-behavioral therapy session designed to increase motivation for follow-up treatment and safety, supplemented by care linkage telephone contacts after emergency department discharge, or usual emergency department care enhanced by provider education. Assessments were conducted at baseline and approximately two months after discharge from the emergency department or hospital. The primary outcome measure was rates of outpatient mental health treatment after discharge. RESULTS Intervention patients were significantly more likely than usual care patients to attend outpatient treatment (92% versus 76%; p=.004). The intervention group also had significantly higher rates of psychotherapy (76% versus 49%; p=.001), combined psychotherapy and medication (58% versus 37%; p=.003), and psychotherapy visits (mean 5.3 versus 3.1; p=.003). Neither the emergency department intervention nor community outpatient treatment (in exploratory analyses) was significantly associated with improved clinical or functioning outcomes. CONCLUSIONS Results support efficacy of the enhanced emergency department intervention for improving linkage to outpatient mental health treatment but underscore the need for improved community outpatient treatment to prevent suicide, suicide attempts, and poor clinical and functioning outcomes for suicidal youths treated in emergency departments.

Primary Care Based Intervention to Reduce At-Risk Drinking in Older Adults: A Randomized Controlled Trial

AIMS To examine whether a multi-faceted intervention among older at-risk drinking primary care patients reduced at-risk drinking and alcohol consumption at 3 and 12 months. DESIGN Randomized controlled trial. SETTING Three primary care sites in southern California. PARTICIPANTS Six hundred and thirty-one adults aged ≥ 55 years who were at-risk drinkers identified by the Comorbidity Alcohol Risk Evaluation Tool (CARET) were assigned randomly between October 2004 and April 2007 during an office visit to receive a booklet on healthy behaviors or an intervention including a personalized report, booklet on alcohol and aging, drinking diary, advice from the primary care provider and telephone counseling from a health educator at 2, 4 and 8 weeks. MEASUREMENTS The primary outcome was the proportion of participants meeting at-risk criteria, and secondary outcomes were number of drinks in past 7 days, heavy drinking (four or more drinks in a day) in the past 7 days and risk score. FINDINGS At 3 months, relative to controls, fewer intervention group participants were at-risk drinkers [odds ratio (OR) 0.41; 95% confidence interval (CI) 0.22-0.75]; they reported drinking fewer drinks in the past 7 days [rate ratio (RR) 0.79; 95% CI 0.70-0.90], less heavy drinking (OR 0.46; 95% CI 0.22-0.99) and had lower risk scores (RR 0.77 95% CI 0.63-0.94). At 12 months, only the difference in number of drinks remained statistically significant (RR 0.87; 95% CI 0.76-0.99). CONCLUSIONS A multi-faceted intervention among older at-risk drinkers in primary care does not reduce the proportions of at-risk or heavy drinkers, but does reduce amount of drinking at 12 months.
