Evidence Base for Collaborative Care
A substantial body of evidence for Collaborative Care has emerged since its development at the University of Washington in the 1990s. Beginning with the seminal IMPACT Trial published in 2002, more than ninety randomized controlled trials and several meta-analyses show that Collaborative Care (CoCM) is more effective than usual care for patients with depression, anxiety, and other behavioral health conditions.
