BACKGROUND: In primary care settings, prevalence estimates of major depressive disorder range from 5% to 13% in all adults, with lower estimates in those older than 55 years (6% to 9%). In 2002, the U.S. Preventive Services Task Force (USPSTF) recommended screening adults for depression in clinical practices that have systems to ensure accurate diagnosis, effective treatment, and follow-up.
PURPOSE: To conduct a targeted, updated systematic review for the U.S. Preventive Services Task Force about the benefits and harms of screening adult patients for depression in a primary care setting, the benefits of depression treatment in older adults, and the harms of depression treatment with antidepressant medications.
DATA SOURCES: MEDLINE, the Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects, PsycINFO (1998 to 2007), expert suggestions, and bibliographies of recent systematic reviews.
STUDY SELECTION: Fair- to good-quality randomized clinical trials or controlled clinical trials; systematic reviews; meta-analyses; and large observational studies of serious adverse events and early discontinuation due to adverse effects. All studies were published in English.
DATA EXTRACTION: Two investigators abstracted, critically appraised, and synthesized 33 articles that met inclusion criteria.
DATA SYNTHESIS: Nine fair- or good-quality trials indicate that primary care depression screening and care management programs with staff assistance, such as case management or mental health specialist involvement, can increase depression response and remission. Benefit was not evident in screening programs without staff assistance in depression care. Seven regulatory reviews or meta-analyses and 3 large cohort studies indicate no increased risk for completed suicide deaths with antidepressant treatment. Risk for suicidal behaviors was increased in young adults (aged 18 to 29 years) who received antidepressants, particularly those who received paroxetine, but was reduced in older adults.
LIMITATION: Examination of harms was limited to serious adverse events, and existing systematic reviews were primarily used. Additional studies published from 2007 to 2008 extend this review.
CONCLUSION: Depression screening programs without substantial staff-assisted depression care supports are unlikely to improve depression outcomes. Close monitoring of all adult patients who initiate antidepressant treatment, particularly those younger than 30 years, is important both for safety and to ensure optimal treatment.
