The IMPACT collaborative care model appears to be feasible and significantly more effective than usual care for depression in a wide range of primary care practices.

STEOARTHRITIS IS THE MOSTcommon type of arthritis among older adults. 1 Its prevalence increases sharply with age. About one third of individuals older than 65 years experience symptomatic osteoarthritis of the knee, and almost 80% of persons have degenerative joint disease after age 70 years. [2][3][4] Arthritis is a leading cause of disability for older persons, reduces quality of life, and accounts for one eighth of all restricted activity days. 5,6 The combined medical and economic costs associated with arthritis are staggering, posing a significant public health problem. 1,7 Depression is also common among older persons, with a prevalence of

Collaborative care improves affective and functional status in older patients with depression and diabetes; however, among patients with good glycemic control, such care minimally affects diabetes-specific outcomes.

The study blends methods from health services and clinical research in an effort to protect internal validity while maximizing the generalizability of results to diverse health care systems. We hope that this study will show the cost-effectiveness of a new model of care for late life depression that can be applied in a range of primary care settings.
