Other Name: Improving Mood-Promoting Access to Collaborative Treatment
No Intervention: Care as Usual
Patients received all depression care available to them as part of care as usual in the participating primary care clinics.
This study tested an organized method of delivering care for late life depression in primary care. Specifically, the investigators evaluated the effectiveness of this intervention as compared to 'care as usual'. The investigators studied the effect of the intervention on clinical outcomes such as depressive symptoms, functional status, health related quality of life. They also determined the cost-effectiveness of the intervention compared to care as usual.
