Screening for generalized anxiety disorder in geriatric primary care patients.

OBJECTIVE: To compare two brief screening measures as tools for detecting generalized anxiety disorder (GAD) among older primary care patients. METHODS: Receiver operating characteristic curve analysis was used to compare the Hospital Anxiety and Depression Scale (HADS) and the Brief Symptom Inventory-18 (BSI-18) against GAD diagnoses obtained from a structured diagnostic interview. RESULTS: The HADS Anxiety subscale was the only measure that distinguished individuals with and without GAD. A cutpoint greater than or equal to 8 on the HADS Anxiety subscale resulted in a sensitivity of 0.967 and a specificity of 0.667 for detecting GAD. CONCLUSIONS: The HADS Anxiety subscale appears to show some advantages over the BSI-18 Anxiety subscale as a brief, self-report measure of anxiety symptoms among older medical patients.

Association between mental health disorders, problem drug use, and regular prescription opioid use.

BACKGROUND: Use of opioids for chronic noncancer pain is increasing, but standards of care for this practice are poorly defined. Psychiatric disorders are associated with increased physical symptoms such as pain and may be associated with opioid use, but no prospective population-based studies have addressed this issue. METHODS: Analysis of longitudinal data from 6439 participants in the 1998 and 2001 waves of Healthcare for Communities, a nationally representative telephone community survey. RESULTS: Two hundred thirty-seven subjects (3.6%) reported regular prescription opioid use in 2001. In unadjusted logistic regression models, respondents with a common mental health disorder in 1998 (1165 [12.6%]; major depression, dysthymia, generalized anxiety disorder, or panic disorder) were more likely to report opioid use in 2001 than those without any of these disorders (odds ratio [OR], 4.43; 95% confidence interval [CI], 3.64-5.38; P<.001). Risk was increased for initiation (OR, 3.26; 95% CI, 2.44-4.34; P<.001) and continuation (OR, 2.30; 95% CI, 1.02-5.17; P = .04) of opioids. Respondents reporting problem drug use (136 [2.0%]; OR, 3.57; 95% CI, 2.32-5.50; P<.001) but not problem alcohol use (401 [6.5%]; OR, 0.73; 95% CI, 0.43-1.24; P = .25) reported higher rates of prescribed opioid use than those without problem use. In multivariate logistic regression models controlling for 1998 demographic and clinical variables, common mental health disorder (OR, 1.96; 95% CI, 1.47-2.62; P<.001) and problem drug use (OR, 2.98; 95% CI, 1.68-5.30; P<.001) remained significant predictors of opioid use in 2001. CONCLUSIONS: Common mental health disorders and problem drug use are associated with initiation and use of prescribed opioids in the general population. Attention to psychiatric disorders is important when considering opioid therapy.

Perceived need for alcohol, drug, and mental health treatment.

BACKGROUND: To investigate determinants of perceived need for alcohol, drug, and mental (ADM) health treatment and differences in ADM treatment patterns between individuals with perceived need and those without. METHODS: We used data from a nationally representative telephone survey of 9585 adults conducted in 1997-1998. Logistic regression was used to study the determinants of perceived need and the correlation between perceived need and any ADM treatment, specialty ADM treatment, appropriate care, and medication adherence. RESULTS: Just fewer than 37% of individuals with an ADM disorder perceived a need for treatment, while 4.6% of those without an ADM disorder perceived a need for treatment. Women, the young and middle aged, the better educated, those with greater emotional support, and those with greater psychiatric morbidity were more likely to perceive need for ADM services. Perceived need was strongly correlated with receiving ADM treatment, although almost 44% of individuals in ADM treatment did not perceive a need for treatment. Among individuals in ADM treatment, those with perceived need were significantly more likely to receive specialty ADM treatment, but not more likely to be treatment adherent, or to receive appropriate care. CONCLUSION: Substantial levels of unmet need are likely to persist as long as perceived levels of need remain low. Interventions targeting perceived need may hold promise for decreasing unmet need.

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

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 patient's 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.

Long-term effectiveness and cost of a systematic care program for bipolar disorder.

CONTEXT: Despite the availability of efficacious treatments, the long-term course of bipolar disorder is often unfavorable. OBJECTIVE: To test the effectiveness of a multicomponent intervention program to improve the quality of care and long-term outcomes for persons with bipolar disorder. DESIGN: Randomized controlled trial with allocation concealment and blinded outcome assessment. SETTING: Mental health clinics of a group-model prepaid health plan. PATIENTS: Of 785 patients in treatment for bipolar disorder who were invited to participate, 509 attended an evaluation appointment, 450 were found eligible to participate, and 441 enrolled in the trial. INTERVENTIONS: Participants were randomly assigned to a multicomponent intervention program or to continued care as usual. Three nurse care managers provided a 2-year systematic intervention program, including the following: a structured group psychoeducational program, monthly telephone monitoring of mood symptoms and medication adherence, feedback to treating mental health providers, facilitation of appropriate follow-up care, and as-needed outreach and crisis intervention. MAIN OUTCOME MEASURES: In-person blinded research interviews every 3 months assessed mood symptoms using the Longitudinal Interval Follow-up Examination. Health plan administrative records were used to assess the use and cost of mental health services. RESULTS: Intent-to-treat analyses demonstrated that the intervention significantly reduced the mean level of mania symptoms (z = 2.09, P = .04) and the time with significant mania symptoms (19.2 vs 24.7 weeks; F(1) = 6.0, P = .01). There was no significant intervention effect on mean level of depressive symptoms (z = 0.19, P = .85) or time with significant depressive symptoms (47.6 vs 50.7 weeks; F(1) = 0.56, P = .45). Benefits of the intervention were found only in a subgroup of 343 persons with clinically significant mood symptoms at the baseline assessment. The incremental cost (adjusted) of the intervention was 1251 dollars (95% confidence interval, 55-2446 dollars), including approximately 800 dollars for the intervention program services and an approximate 500 dollars increase in the costs of other mental health services. CONCLUSIONS: Population-based systematic care programs can significantly reduce the frequency and severity of mania in bipolar disorder, and cost increases are modest considering the clinical gains. The incorporation of more specific cognitive and behavioral content or more effective medication regimens may be necessary to significantly reduce the symptoms of depression.

Project IMPACT: a report on barriers and facilitators to sustainability.

Project IMPACT is a collaborative care intervention to assist older adults suffering from major depressive disorder or dysthymia. Qualitative research methods were used to determine the barriers and facilitators to sustaining IMPACT in a primary care setting. Strong evidence supports the program's sustainability, but considerable variation exists in continuation strategies and operationalization across sites. Sustainability depended on the organizations' support of collaborative care models, the availability of staff trained in the intervention, and funding. The intervention's success was the most important sustainability factor, as documented by outcome data and through the "real world" experience of treating patients with this intervention.

Depression treatment preferences in older primary care patients.

PURPOSE: For depressed older primary care patients, this study aimed to examine (a) characteristics associated with depression treatment preferences; (b) predictors of receiving preferred treatment; and (c) whether receiving preferred treatment predicted satisfaction and depression outcomes. DESIGN AND METHODS: Data are from 1,602 depressed older primary care patients who participated in a multisite, randomized clinical trial comparing usual care to collaborative care, which offered medication and counseling for up to 12 months. Baseline assessment included demographics, depression, health information, prior depression treatment, potential barriers, and treatment preferences (medication, counseling). At 12 months, services received, satisfaction, and depression outcomes were assessed. RESULTS: More patients preferred counseling (57%) than medication (43%). Previous experience with a treatment type was the strongest predictor of preference. In addition, medication preference was predicted by male gender and diagnosis of major depression (vs dysthymia). The collaborative care model greatly improved access to preferred treatment, especially for counseling (74% vs 33% in usual care). Receipt of preferred treatment did not predict satisfaction or depression outcomes; these outcomes were most strongly impacted by treatment condition. IMPLICATIONS: Many depressed older primary care patients desire counseling, which is infrequently available in usual primary care. Discussion of treatment preferences should include an assessment of prior treatment experiences. A collaborative care model that increases collaboration between primary care and mental health professionals can increase access to preferred treatment. If preferred treatment is not available, collaborative care still results in good satisfaction and depression outcomes.

Cognitive impairment and depression outcomes in the IMPACT study.

INTRODUCTION: It is unclear whether cognitive impairment affects acute and long-term treatment response in geriatric depression. In addition, little is known about the long-term outcome of depression among older individuals who experience cognitive decline during a course of treatment for depression. The authors examined both of these issues using data from the IMPACT trial. METHODS: The sample consisted of 1,684 participants in the IMPACT study who had baseline and two-year follow-up data. Subjects were randomized to one year of active intervention with a depression care manager or usual care. After one year, all subjects had usual care for another year. Data were collected for two years. The authors used the Six-Item Cognitive Screener to examine acute and long-term effects on depression outcome of baseline cognitive impairment and of cognitive decline. Depression measures included the HSCL-20 and an estimation of depression-free days. Outcomes were determined using both linear regression and repeated-measures analyses. RESULTS: Depressed subjects in the active intervention group had better depression outcomes at one year regardless of baseline cognitive impairment. Cognitively impaired subjects within each treatment group had similar outcomes to subjects without cognitive impairment. Subjects who experienced decline in cognitive score over two years had worse 24-month depression outcomes compared with subjects whose cognitive score did not change. CONCLUSIONS: Cognitively impaired depressed patients can experience significant improvement in depression with appropriate acute and continuation-phase management. Older depressed adults experiencing ongoing cognitive decline may be at higher risk for poor depression outcomes and may require more careful clinical monitoring and management of both cognitive and affective symptoms.

Depressive symptom deterioration in a large primary care-based elderly cohort.

OBJECTIVE: The purpose of this study is to examine the incidence and clinical predictors of symptom deterioration in depressed elderly patients who have responded to treatment in primary care. METHOD: A cohort study of 901 older adults from 18 primary care clinics in five states who met Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria for major depression and/or dysthymia at baseline interview, had participated in a trial of collaborative care for depression compared to usual care, and had improved to the point of no longer meeting criteria for major depression at 12 months were observed for one year (18 and 24 months) after enrolling in the original study. RESULTS: A total of 40% of patients met criteria for significant depressive symptom deterioration over the 12- to 24-month observational period. Among usual-care patients, higher initial severity of depression and a higher number of residual DSM-IV depressive symptoms at 12 months were significant predictors of symptom deterioration. No variables predicted symptom deterioration in intervention patients. CONCLUSIONS: There is a high rate of symptom deterioration among elderly patients in primary care who are treated for depression. Efforts to improve long-term outcomes of older patients with major depression and/or dysthymia should focus on providing more intensive treatment and follow up for patients with residual depressive symptoms.

Gender disparities in the treatment of late-life depression: qualitative and quantitative findings from the IMPACT trial.

OBJECTIVES: The objectives of this study were to examine gender differences in recruitment, depression presentation, and depression treatment history in a large effectiveness trial; and to use qualitative data to generate hypotheses about reasons for observed gender differences. METHODS: Data from IMPACT, a multisite trial of a disease management program for late-life depression in primary care were used to examine gender differences quantitatively. Qualitative interviews were conducted with 30 key informants from IMPACT (referring physicians, depression care managers, and study recruiters) to learn more about challenges in recruiting and treating depressed older men and then analyzed thematically. RESULTS: Compared with older women, older men were significantly less likely to be referred to IMPACT, to endorse core depressive symptoms, and to have received prior depression treatment. Gender differences in prior depression treatment persisted after adjustment for covariates. Qualitative themes identified as important contributors to gender disparities included 1) how men experience and express their depression, 2) traditional masculine values, and 3) the stigma of chronic mental illness. CONCLUSION: This study provides further evidence of the gender gap in depression care, identifies possible contributing factors, and suggests avenues for future research.

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. DESIGN: Randomized, controlled trial. SETTING: Eighteen diverse primary care clinics. PARTICIPANTS: One thousand eight hundred one adults aged 60 and older with major depression or dysthymia. INTERVENTION: Participants randomized to collaborative care had access to a depression care manager who supported antidepressant medication management prescribed by their primary care physician and offered a course of Problem Solving Treatment in Primary Care for 12 months. Participants in the control arm received care as usual. MEASUREMENTS: Participants had independent assessments of depression and suicidal ideation at baseline and 3, 6, 12, 18, and 24 months. Depression was assessed using the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (SCID). Suicidal ideation was determined using the SCID and the Hopkins Symptoms Checklist. RESULTS: At baseline, 139 (15.3%) intervention subjects and 119 (13.3%) controls reported thoughts of suicide. Intervention subjects had significantly lower rates of suicidal ideation than controls at 6 months (7.5% vs 12.1%) and 12 months (9.8% vs 15.5%) and even after intervention resources were no longer available at 18 months (8.0% vs 13.3%) and 24 months (10.1% vs 13.9%). There were no completed suicides in either group. Information on suicide attempts or hospitalization for suicidal ideation was not available. CONCLUSION: Primary care-based collaborative care programs for depression represent one strategy to reduce suicidal ideation and potentially the risk of suicide in older primary care patients.

Transforming mental health care at the interface with general medicine: report for the presidents commission.

This paper is based on a report commissioned by the Subcommittee on Mental Health Interface With General Medicine of the Presidents New Freedom Commission on Mental Health. Although mental and medical conditions are highly interconnected, medical and mental health care systems are separated in many ways that inhibit effective care. Treatable mental or medical illnesses are often not detected or diagnosed properly, and effective services are often not provided. Improved mental health care at the interface of general medicine and mental health requires educated consumers and providers; effective detection, diagnosis, and monitoring of common mental disorders; valid performance criteria for care at the interface of general medicine and mental health; care management protocols that match treatment intensity to clinical outcomes; effective specialty mental health support for general medical providers; and financing mechanisms for evidence-based models of care. Successful models exist for improving the collaboration between medical and mental health providers. Recommendations are presented for achieving high-quality care for common mental disorders at the interface of general medicine and mental health and for overcoming barriers and facilitating use of evidence-based quality improvement models.

Implementation and maintenance of quality improvement for treating depression in primary care.

OBJECTIVE: Little is known about the long-term success of quality improvement efforts for the treatment of depression in primary care. This study assessed factors associated with the successful implementation, maintenance, and spread of such efforts. METHODS: The authors conducted an independent process evaluation of data from monthly progress reports and 18-month telephone interviews from multidisciplinary quality improvement teams in 17 diverse primary care organizations that participated in the Institute for Healthcare Improvement's Breakthrough Series for Depression from February 2000 through March 2001. RESULTS: All sites made changes toward improving care in three of six categories: delivery system redesign, self-management strategies, and information systems. The changes that were most commonly viewed as major successes were delivery system changes (ten sites, or 59 percent) and information system changes (nine sites, or 53 percent); these types of changes were also the most often sustained over time (ten sites, or 59 percent, and 16 sites, or 94 percent, respectively). Fifteen sites made changes in decision support, community linkages, and health system support but were less likely to view these changes as major successes or to sustain them. Organizational structure and leadership support were the most common facilitators. Staff resistance, time constraints, and information technology were the most common barriers. Implementation strategies varied with sets of barriers. CONCLUSIONS: Despite substantial challenges, there was evidence of broad success at implementation and maintenance of quality improvement for depression treatment in primary care.

Cost-effectiveness and net benefit of enhanced treatment of depression for older adults with diabetes and depression.

OBJECTIVE: To determine the incremental cost-effectiveness and net benefit of a depression collaborative care program compared with usual care for patients with diabetes and depression. RESEARCH DESIGN AND METHODS: This article describes a preplanned subgroup analysis of patients with diabetes from the Improving Mood-Promoting Access to Collaborative (IMPACT) randomized controlled trial. The setting for the study included 18 primary care clinics from eight health care organizations in five states. A total of 418 of 1,801 patients randomized to the IMPACT intervention (n = 204) versus usual care (n = 214) had coexisting diabetes. A depression care manager offered education, behavioral activation, and a choice of problem-solving treatment or support of antidepressant management by the primary care physician. The main outcomes were incremental cost-effectiveness and net benefit of the program compared with usual care. RESULTS: Relative to usual care, intervention patients experienced 115 (95% CI 72-159) more depression-free days over 24 months. Total outpatient costs were 25 dollars (95% CI -1,638 to 1,689) higher during this same period. The incremental cost per depression-free day was 25 cents (-14 dollars to 15 dollars) and the incremental cost per quality-adjusted life year ranged from 198 dollars (144-316) to 397 dollars (287-641). An incremental net benefit of 1,129 dollars (692-1,572) was found. CONCLUSIONS: The IMPACT intervention is a high-value investment for older adults with diabetes; it is associated with high clinical benefits at no greater cost than usual care.

Regular use of prescribed opioids: association with common psychiatric disorders.

Use of opioids for chronic non-cancer pain is increasing, but the clinical epidemiology and standards of care for this practice are poorly defined. Psychiatric disorders are associated with increased physical symptoms and may be associated with opioid use. We performed a secondary analysis of cross-sectional data from the Health Care for Communities (HCC) survey conducted in 1997-1998 (N=9279) to determine the association of psychiatric disorders and self-reported regular use of prescribed opioids within the past year. Regular prescription opioid use was reported by 282 (3%) respondents. In unadjusted logistic regression models, respondents with common mental disorders in the past year (major depression, dysthymia, generalized anxiety disorder, or panic disorder) were more likely to report regular prescription opioid use than those without any of these disorders (OR=6.15, 95% CI=4.13, 9.14, P< 0.001). Respondents reporting problem drug use (OR=4.75, 95% CI=2.52, 8.94, P<0.001), or problem alcohol use (OR=1.89, 95% CI=1.03, 3.40, P=.041) reported higher rates of prescribed opioid use than those without problem use. In multivariate logistic regression models controlling for demographic and clinical variables, the presence of a common mental disorder remained a significant predictor of prescription opioid use (OR=3.15, 95% CI=1.69, 5.88, P<0.001), among individuals reporting low pain interference (N=8307); but not (OR=1.27, n.s.) among those reporting high pain interference (N=972). Depressive, anxiety and drug abuse disorders are associated with increased use of regular opioids in the general population. Depressive and anxiety disorders are more common and more strongly associated with prescribed opioid use than drug abuse disorders.

A comparison of imputation methods in a longitudinal randomized clinical trial.

It is common for longitudinal clinical trials to face problems of item non-response, unit non-response, and drop-out. In this paper, we compare two alternative methods of handling multivariate incomplete data across a baseline assessment and three follow-up time points in a multi-centre randomized controlled trial of a disease management programme for late-life depression. One approach combines hot-deck (HD) multiple imputation using a predictive mean matching method for item non-response and the approximate Bayesian bootstrap for unit non-response. A second method is based on a multivariate normal (MVN) model using PROC MI in SAS software V8.2. These two methods are contrasted with a last observation carried forward (LOCF) technique and available-case (AC) analysis in a simulation study where replicate analyses are performed on subsets of the originally complete cases. Missing-data patterns were simulated to be consistent with missing-data patterns found in the originally incomplete cases, and observed complete data means were taken to be the targets of estimation. Not surprisingly, the LOCF and AC methods had poor coverage properties for many of the variables evaluated. Multiple imputation under the MVN model performed well for most variables but produced less than nominal coverage for variables with highly skewed distributions. The HD method consistently produced close to nominal coverage, with interval widths that were roughly 7 per cent larger on average than those produced from the MVN model.
