Collaborative Care Model (CoCM) is an integrated care approach developed at the University of Washington to address common mental health conditions in medical settings, such as primary care. Behavioral health issues, including depression, anxiety, PTSD, and alcohol or substance use disorders, are among the most prevalent and disabling health conditions worldwide. CoCM is based on effective chronic illness care principles and focuses on specific patient populations tracked in a registry to monitor treatment progress. The treatment plan emphasizes measurement-based approaches to ensure that patients' goals and clinical outcomes are achieved.
