“…The U.S. health care system's historical separation of medical and BH sectors-in terms of clinical practice, administration, and financing-is widely considered to be a significant contributor to the comparatively poor overall health outcomes associated with mental illness (Druss, 2007;Horvitz-Lennon, Kilbourne, and Pincus, 2006; Committee on Crossing the Quality Chasm: Adaptation to Mental Health and Addictive Disorders, Board on Health Care Services, Institute of Medicine, 2006;Pincus et al, 2007;President's New Freedom Commission on Mental Health, 2003). As such, initiatives that promote medical and BH integration-for example, through co-location of primary and BH care services, clinical changes such as collaborative care teams, or payment reforms-are increasingly common health care reforms (Druss and Mauer, 2010;Katon and Unützer, 2013;Smith et al, 2012).…”
