Improving the primary care treatment of late life depression: progress and opportunities

Elderly care recipients' perceptions of treatment helpfulness for depression and the relationship with help-seeking

Objective

This study aims to examine perceptions of the helpfulness of treatments/interventions for depression held by elderly care recipients, to examine whether these beliefs are related to help-seeking and whether the experience of depression affects beliefs about treatment seeking, and to identify the characteristics of help-seekers.

Method

One hundred eighteen aged care recipients were surveyed on their beliefs about the helpfulness of a variety of treatments/interventions for depression, on their actual help-seeking behaviors, and on their experience of depression (current and past).

Results

From the sample, 32.4% of the participants screened positive for depression on the Geriatric Depression Scale, and of these, 24.2% reported receiving treatment. Respondents believed the most helpful treatments for depression were increasing physical activity, counseling, and antidepressant medication. Help-seeking from both professional and informal sources appeared to be related to belief in the helpfulness of counseling and antidepressants; in addition, help-seeking from informal sources was also related to belief in the helpfulness of sleeping tablets and reading self-help books. In univariate analyses, lower levels of cognitive impairment and being in the two lower age tertiles predicted a greater likelihood of help-seeking from professional sources, and female sex and being in the lower two age tertiles predicted greater likelihood of help-seeking from informal sources. In multivariate analyses, only lower levels of cognitive impairment remained a significant predictor of help-seeking from professional sources, whereas both lower age and female sex continued to predict a greater likelihood of help-seeking from informal sources.

Conclusion

Beliefs in the helpfulness of certain treatments were related to the use of both professional and informal sources of help, indicating the possibility that campaigns or educational programs aimed at changing beliefs about treatments may be useful in older adults.

Mental health treatment seeking among older adults with depression: the impact of stigma and race

OBJECTIVE

Stigma associated with mental illness continues to be a significant barrier to help seeking, leading to negative attitudes about mental health treatment and deterring individuals who need services from seeking care. This study examined the impact of public stigma (negative attitudes held by the public) and internalized stigma (negative attitudes held by stigmatized individuals about themselves) on racial differences in treatment-seeking attitudes and behaviors among older adults with depression.

METHOD

Random digit dialing was utilized to identify a representative sample of 248 African American and white older adults (older than 60 years) with depression (symptoms assessed by the Patient Health Questionnaire-9). Telephone-based surveys were conducted to assess their treatment-seeking attitudes and behaviors and the factors that impacted these behaviors.

RESULTS

Depressed older adult participants endorsed a high level of public stigma and were not likely to be currently engaged in or did they intend to seek mental health treatment. Results also suggested that African American older adults were more likely to internalize stigma and endorsed less positive attitudes toward seeking mental health treatment than their white counterparts. Multiple regression analysis indicated that internalized stigma partially mediated the relationship between race and attitudes toward treatment.

CONCLUSION

Stigma associated with having a mental illness has a negative influence on attitudes and intentions toward seeking mental health services among older adults with depression, particularly African American elders. Interventions to target internalized stigma are needed to help engage this population in psychosocial mental health treatments.

Utilization of mental health care services among older adults with depression

Despite the availability of effective treatments for late life depression, data indicate that only a small minority of adults over the age of 65 years with depression access any kind of care for emotional or mental health problems. Using data from the Canadian Community Health Survey (Cycle 1.1), we compared patterns of mental health service utilization among middle-aged (45-64 years), younger old (65-74 years), and older old (75 years and older) adults with and without depression and identified predictors associated with accessing different services (n=59,302). Compared to middle-aged adults with depression, individuals aged 65 and older with depression were less likely to report any mental health consultation in the past year and especially unlikely to report consulting with professionals other than a family physician. Age remained a significant predictor of mental health service utilization even after accounting for other relevant variables such as gender, marital status, years of education, depression caseness, and number of chronic medical conditions. Although the prevalence of depression is lower in older age groups, the present study provides compelling evidence that mental health services are particularly underutilized by depressed older adults.

Effect of race and sex on primary care physicians' diagnosis and treatment of late-life depression

OBJECTIVES

To examine primary care physician (PCP) contributions toward racial and sex differences in the diagnosis and treatment of late-life depression.

DESIGN

Survey using a computerized instrument incorporating video interviews and text, with volunteer PCPs randomly assigned to one of four standardized video vignettes of an elderly patient depicting late-life depression. Vignettes differed only in the patient/actor's race (white/African-American) or sex.

SETTING

American Academy of Family Physicians meeting, San Diego, California, 2002.

PARTICIPANTS

One hundred seventy-eight U.S.-practicing postresidency PCPs who were asked to participate in a clinical decision-making study.

MEASUREMENTS

The computerized survey instrument assessed PCPs' diagnoses, first-line treatment and management recommendations, and judgment of personal characteristics/behaviors for the patients in the vignettes.

RESULTS

Eighty-five percent of all PCPs correctly diagnosed the elderly patient(s) with major depression. There were no significant differences in the diagnosis of depression, treatment recommendations, or PCP assessment of most patient characteristics by the race or sex of the patient/actor in the vignette, but PCP characteristics, most notably the location of medical school training (U.S. vs international), affected the likelihood of a depression diagnosis and treatment recommendations.

CONCLUSION

Given standardized symptom-pictures, PCPs are just as likely to diagnose and treat depression in African-American as in white older people, suggesting that bias based simply on apparent patient race is not a likely explanation for the lower rates of depression diagnosis and treatment in older African Americans. PCPs who have trained at international medical schools may benefit from targeted training initiatives on the diagnosis and treatment of late-life depression.

Use of brief depression screening tools in primary care: consideration of heterogeneity in performance in different patient groups

Heterogeneity of performance of screening tools in different patient groups has rarely been considered in the literature on depression screening in primary care. The objectives of the present study were to assess and to compare diagnostic accuracy of three screening questionnaires (Brief Patient Health Questionnaire, General Health Questionnaire-12, WHO-5) in identifying depression across various patient subpopulations and to assess the accuracy of the unaided clinical assessment of primary care physicians in the same subgroups. We conducted a cross-sectional validation study in 448 primary care patients. Two-by-two tables as well as receiver operating characteristics were applied. Results indicated that diagnostic accuracy (sensitivity, specificity) of the three screening instruments as well as of the clinical diagnoses differed in the various patient groups. Superiority of one screening tool over the other depends on the subgroup considered. Gender, age, form (subtype), and severity of depression influence the test characteristics of a screening tool. This should be considered if routine depression screening should be widely introduced. Of course, the benefit of routine screening also depends on efforts made for treatment and monitoring of patients in whom depression was diagnosed.

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

DESIGN

Cross sectional survey data collected from 1999 to 2001 as part of a treatment effectiveness trial.

SETTING

Eighteen primary care clinics belonging to eight organizations in five states.

PARTICIPANTS

One thousand eight hundred one clinic users aged 60 and older who met diagnostic criteria for major depression or dysthymia.

MEASUREMENTS

Lifetime depression treatment was defined as ever having received a prescription medication, counseling, or psychotherapy for depression. Potentially effective recent depression treatment was defined as 2 or more months of antidepressant medications or four or more sessions of counseling or psychotherapy for depression in the past 3 months.

RESULTS

The mean age +/- standard deviation was 71.2 +/- 7.5; 65% of subjects were women. Twenty-three percent of the sample came from ethnic minority groups (12% were African American, 8% were Latino, and 3% belonged to other ethnic minorities). The median household income was $23,000. Most study participants (83%) reported depressive symptoms for 2 or more years, and most (71%) reported two or more prior depressive episodes. About 65% reported any lifetime depression treatment, and 46% reported some depression treatment in the past 3 months, although only 29% reported potentially effective recent depression treatment. Most of the treatment provided consisted of antidepressant medications, with newer antidepressants such as selective serotonin reuptake inhibitors constituting the majority (78%) of antidepressants used. Most participants indicated a preference for counseling or psychotherapy over antidepressant medications, but only 8% had received such treatment in the past 3 months, and only 1% reported four or more sessions of counseling. Men, African Americans, Latinos, those without two or more prior episodes of depression, and those who preferred counseling to antidepressant medications reported significantly lower rates of depression care.

CONCLUSION

The findings suggest that there is considerable opportunity to improve care for older adults with depression. Particular efforts should be focused on improving access to depression care for older men, African Americans, Latinos, and patients who prefer treatments other than antidepressants.

Screening for depression in medical care: pitfalls, alternatives, and revised priorities

Depression is a disorder seen commonly in general and specialty medical settings. Screening has been advocated as a means of ensuring that depressed patients are identified and receive appropriate treatment. Yet, recommendations for routine screening are frequently made without reference to empirical data demonstrating that it will have its intended effect. We examine the literature regarding screening in medical settings and suggest that screening in itself is unlikely to improve patient outcomes. Further, we identify costs to screening that are not readily apparent and that may negatively affect both patient outcomes and health-care delivery systems. We offer suggestions for how screening instruments might be used to improve the outcomes of depressed persons while minimizing negative effects on health care.

Impacting late life depression: integrating a depression intervention into primary care

groups and semi-structured individual interviews with all Depression Clinical Specialists (DCSs) working with Project IMPACT (Improving Mood: Promoting Access to Collaborative Treatment), a study testing a collaborative care intervention for late life depression, to examine integration of the intervention model into primary care. DCSs described key intervention components, including supervision from a psychiatrist and a liaison primary care provider, weekly team meetings, computerized patient tracking, and outcomes assessment tools as effective in supporting patient care. DCSs discussed details of protocols, training, environmental set-up, and interpersonal factors that seemed to facilitate integration. DCSs also identified research-related factors that may need to be preserved in the real world. Basic elements of the IMPACT model seem to support integration of late life depression care into primary care. Research-related components may need modification for dissemination.

Diagnosis and treatment of older adults with depression in primary care

This article provides an overview of current challenges in the diagnosis and treatment of depressed older adults in primary care and considers suggestions for clinicians, researchers, and policy makers to improve care for this population. Despite the enormous toll of depression on individuals and society and the availability of effective treatments, depressed older adults remain largely untreated or undertreated. They rarely see mental health professionals, but have relatively frequent contact with primary care providers. In primary care, the chronic and recurrent nature of depression and a number of patient, provider, and policy-related barriers interfere with effective depression treatment. Recent research suggests that improving care for individuals with late life depression will require education and engagement of older adults and their primary care providers as active partners in caring for depression. It will also require additional human resources and systematic models of care dedicated to proactively managing depression as a chronic illness. Finally, it will require training of mental health professionals to effectively collaborate with their colleagues in primary care in treating depressed older adults. Further improvement in depression care would likely result from the implementation of true parity for mental health treatments for older adults.

Emotional disorders in primary care

Individuals with emotional disorders are more likely to use primary medical care than specialty mental health services, but these disorders are likely to be undetected or inadequately treated. Recognition of the importance of primary medical care for the treatment of mental disorder has resulted in pressing new research priorities. One set of issues concerns the adequacy of existing nosological systems for conceptualizing emotional disorder in primary care and identifying need for treatment. Another concerns the difficulties translating efficacious treatment into effective strategies that can be integrated into the competing demands of primary medical care. Psychologists have played only a limited role in defining and addressing emerging questions. Irreversible changes in mental health services have created the need for the development of a psychosocial perspective for what would otherwise be defined as narrowly biomedical issues.
