Caring for Mental Illness in the United States: A Focus on Older Adults

OBJECTIVE The authors compared rates of common mental disorders and the use of primary care and specialty mental health services among younger and older adults. METHODS They used data from 9,585 respondents to the HealthCare for Communities (HCC) Household Telephone Survey. Mental disorders during the past year, including depression, dysthymia, and generalized anxiety disorder, were identified with a short questionnaire. The survey also collected information about sociodemographic and insurance status, perceived need for mental health care, and use of health services. RESULTS Older adults (age 65 and older) were significantly less likely than younger adults (18-29) or middle-aged adults (30-64) to meet diagnostic criteria for a mental disorder (8% versus 15% in each of the younger age-groups). Older adults who met diagnostic criteria for mental disorders were less likely to perceive a need for mental health care, to receive specialty mental health care or counseling, or to receive referrals from primary care to mental health specialty care than young or middle-aged adults. CONCLUSION Few older adults with mental disorders use mental health services, particularly specialty mental health services. The lack of perceived need for mental health care may contribute to low rates of mental health service use among 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

Quality adjusted life years in older adults with depressive symptoms and chronic medical disorders.

We used data from a 4-year prospective study of 2,558 primary care patients age 65 and older in a large staff model health maintenance organization to examine the association of clinically significant depressive symptoms and eight other chronic medical conditions with quality adjusted life years (QALYs). We developed linear regression models to examine the association of clinically significant depressive symptoms as defined by a score of 16 or greater on the Center for Epidemiological Studies Depression Scale and eight common chronic medical disorders at baseline with QALYs over the 4-year study period. Estimates of QALYs were derived from Quality of Well-Being Scale scores at baseline, at 2-year follow-up, and at 4-year follow-up. Individuals with clinically significant depressive symptoms at baseline had significantly lower QALYs over the 4-year study period than nondepressed subjects, even after adjusting for differences in age, gender, and the eight other chronic medical conditions. In terms of the entire study population, only arthritis and heart disease were more strongly associated with QALYs than depression.

Care for Depression in HMO Patients Aged 65 and Older

OBJECTIVE: To examine treatment for depression among older adults in a large staff model health maintenance organization (HMO).

Depressive symptoms and mortality in a prospective study of 2,558 older adults

OBJECTIVE The authors report results from a 7-year prospective study of depression and mortality in 2,558 Medicare recipients age 65 and older. METHODS This report is based on a secondary data analysis of a randomized controlled trial that evaluated the cost-effectiveness of preventive services for older enrollees in an HMO. RESULTS Subjects with mild-to-moderate depression at baseline did not have an increased risk of mortality compared with those without significant depression. The 3% of older adults with the most severe depressive syndromes, however, had significant increases in mortality, even after adjusting for demographics, health risk behaviors, and chronic medical disorders. CONCLUSION The increase in mortality in this group of older adults was comparable to that in participants with chronic medical disorders such as emphysema or heart disease.

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.

The use of administrative data to assess quality of care for bipolar disorder in a large staff model HMO

We examined patterns of care for 1246 adults treated for bipolar disorder in a large health maintenance organization. Computerized pharmacy and visit data were used to identify patients treated for bipolar disorder. Automated medical records for the following year were used to assess continuity and dosing of treatment with mood stabilizers, laboratory monitoring for adverse effects and therapeutic serum levels, and frequency of follow-up visits. Of our 1246 subjects 83% filled a mood stabilizer prescription during the 1-year study period, and doses were within recommended ranges 80% of the time. Over 75% of the patients on mood stabilizers had at least one apparent interruption in medication use. Approximately half of the long-term users of mood stabilizers had at least one 7-month period without a recorded blood level and approximately half had a similar period without monitoring for adverse medication effects. Of the 116 subjects discharged from a psychiatric hospitalization 58% had a visit with a psychiatrist or a psychiatric nurse practitioner within 30 days. Of those discontinuing mood stabilizer treatment 68% made a mental health visit within 90 days. Our findings demonstrate the feasibility of using administrative data systems for population-based quality of care assessment and suggest opportunities for improving the care of bipolar patients.

Patterns of care for depressed older adults in a large-staff model HMO.

The authors examined automated pharmacy and visit data for 502 members of a large-staff model health maintenance organization (HMO) who had been diagnosed with depression and started on antidepressants by their primary-care providers. Older patients (age >/=60; n=110) were less likely than younger adults (age 18-59, n=110) to receive adequate doses of antidepressant medications for 30 or 90 days. Older adults were also less likely than younger adults to receive more than two primary-care visits for depression in the 12 weeks after receiving a new antidepressant prescription and were less likely to receive specialty mental health care in the 6 months after receiving a new antidepressant prescription.

Low-intensity treatment of depression in primary care: is it problematic?

The aim of this study was to examine patterns of care and outcomes of depressed patients under primary care during acute phase treatment. A cohort of depressed patients was assessed 6-8 weeks after starting pharmacotherapy in four large primary care clinics in a health maintenance organization. These patients (n = 1671) were receiving antidepressant treatment for a new episode of depression. To calculate main outcome measures, Structured Clinical Interview for Depression evaluated prior history and current depression status. Visit and pharmacy refill data described use of health services and antidepressant medication. Six to eight weeks after starting antidepressant therapy, 33.2% of patients had 0-3 depressive symptoms and no prior history of depression, an additional 42.3% also reported 0-3 symptoms but were at high risk of relapse, and 24. 5% were persistently depressed with 4 or more depressive symptoms. In the initial 6 weeks of treatment, these three groups showed similar use of antidepressant medication and health services. About 50% in each group had no follow-up visit for depression and 32%-42% had not refilled their antidepressant prescription. In general, depressed patients under primary care obtained low-intensity pharmacotherapy and inconsistent follow-up visits during initial acute phase treatment. Six weeks after starting antidepressant medicine, many were still symptomatic or recovered but had a high risk of depression relapse. Patients with unfavorable outcomes did not receive more intensive management than the one-third who had favorable outcomes.
