The Substance Abuse and Mental Health Services Administration (SAMHSA) and Administration on Aging (AoA) commissioned a series of Issue Briefs to address behavioral health issues that are important to older Americans. The Issue Briefs identify key information and opportunities for action that can improve the lives of older people. This Issue Brief is intended to help primary and behavioral health care providers develop strategies to integrate care for older adults. It provides (1) Information on the rationale for implementing integrated primary and behavioral health care models; (2) Examples of integrated care models that target older adults; and (3) Recommendations and Resources to help aging services, behavioral health, and primary care providers implement integrated care programs.
