ObjectivesTo evaluate changes in health care spending and utilization associated with a telehealth-based care coach-supported and behavioral health (BH) provider referral intervention in the United States.Study DesignObservational retrospective cohort study with propensity score matching of treated and control groups.MethodsDifference-in-differences (DID) analysis was used to calculate per-member per-month (PMPM) savings and changes in utilization in a treated group relative to matched controls over 36 months. The study included 1800 adults with substance use disorder (SUD), anxiety, or depression who were eligible for the intervention. Treated members (n = 900) graduated from the program. Matched control members (n = 900) were eligible but never enrolled. Primary outcomes included all-cause and disease-attributable health care cost and utilization PMPM, categorized by place of service.ResultsThere were statistically significant reductions in total all-cause medical costs of $485 PMPM (P < .001) and a 66% pre-post reduction in inpatient encounters, with $488 PMPM DID savings for inpatient admissions (P < .001) among the treated cohort compared with the control cohort over 36 months. Conversely, there were statistically significant cost increases ($110 PMPM; P < .001) for all-cause office visits in the treated cohort compared with the control cohort. Similar results were seen in SUD-attributable and BH-attributable costs.ConclusionsAlthough the results could be affected by unmeasured confounding, they suggest that care coaching interventions that offer BH provider referrals may produce long-term savings, reductions in avoidable utilization, and increases in targeted services to treat BH conditions. Rigorous evaluations are needed to confirm these findings.
