Cost Analysis of Integrated Behavioral Health in a Large Primary Care Practice.

A residency-based Family Medicine outpatient clinic chose to implement an integrated behavioral health care program in a large primary care clinic in the Southeast to improve patient access to behavioral health care. We hypothesized that embedding a BHP in a primary care setting would be a cost neutral intervention. We implemented a prospective cohort design and included expenses from both inpatient and outpatient visits. We implemented a mixed effects linear regression model to evaluate pre- and post-BHP exposure costs. A total of 1256 patients were identified in the post-BHP exposure period that had more than one-year post-exposure. After applying exclusion criteria, there were 926 patients included in analysis. These patient had an average total cost during the one-year pre-BHP exposure period of $5113 (SD = 7712) and one-year post-BHP exposure period of $5462 (SD = 7813). Our analysis shows a relatively cost neutral impact following the introduction of BHPs in a primary care setting. The results of this study provide a gauge for future planning of services.
