Implementing a Whole Health Model in a Community Mental Health Center: Impact on Service Utilization and Expenditures.

Objective: This study examined whether implementing a whole health care model in a community mental health center reduced the use of acute care services and total Medicare expenditures. The whole health care model embedded monitoring of overall health and wellness education within the center's outpatient mental and substance use disorder treatment services, and it improved care coordination with primary care providers.

Methods: This study used fee-for-service Medicare administrative claims and enrollment data for June 2009 through July 2015 for the intervention (N=846) and matched comparison group (N=2,643) to estimate a difference-in-differences model.
