More than 20 years of research evidence across more than 80 randomized controlled trials has established Collaborative Care as the integrated care approach with the most research evidence across all kinds of clinical delivery systems, patient populations, and geographic regions. This research evidence is replicated in dozens of peer reviewed publications evaluating implementation of Collaborative Care in real-world settings. Kaiser Permanente is committed to providing the highest quality care possible to their patients. They participated in the largest research trial of Collaborative Care and one of their regions has been practicing Collaborative Care for many years. The senior leaders at each of the eight regions, along with leadership from the national Mental Health and Wellness group, have made implementing Collaborative Care system-wide a key priority. The AIMS Center is partnering with them to accomplish this goal.
