John Roseman, MD, Behavioral Health Clinical Content Lead, Jennifer Gray, RN, Application Manager, Andrew Murphy, Application Coordinator, and Liann Devereux, Application Coordinator, Partners HealthCare System. After three years of enterprise discussion and consensus on workflows and content, Partners began a new EMR implementation process in 2015. This has resulted in the successful implementation of the Epic EMR at Partners in multiple sites including their academic medical centers, community hospitals, outpatient clinics and home health community. Concurrently, Partners has established a Behavioral Health EMR to provide tools and resources for primary care and ancillary providers to help them manage patients with depression and other mental health disorders. The outpatient and inpatient behavioral health EMR build was completed in 2015; the dedicated Mental Health facility has truly challenged their overall behavioral health EMR and will go live the end of June 2017. Dr. Roseman, Jennifer, Andrew and Liann share their lessons learned to date on the integration of behavioral and physical health in their EMR build and rollout. They also share what they are planning to address as they continue to enhance and develop their EMR to appropriately cultivate a unique approach to this important dimension in improved patient care management.
