The treatment of depression in older adults in the primary care setting: an evidence-based review.

The objective of this study was to conduct an evidence-based review of treatments for depression in older adults in the primary care setting. A literature search was conducted using PsycINFO and Medline to identify relevant, English language studies published from January 1994 to April 2004 with samples aged 55 and older. Studies were required to be randomized controlled trials that compared psychosocial interventions conducted within the primary care setting with "usual care" conditions. Eight studies with older adult samples met inclusion criteria and were included in the review. Two treatment models were evident: Geriatric Evaluation Management (GEM) clinics and an approach labeled integrated health care models. Support was found for each model, with improvement in depressive symptoms and better outcomes than usual care; however, findings varied by depression severity, and interventions were difficult to compare. Further efforts to improve research and clinical care of depression in the primary care setting for older adults are needed. The authors recommend the use of interdisciplinary teams and more implementation of psychosocial treatments shown to be effective for older adults.
