Impacts of the Certified Community Behavioral Health Clinic Demonstration on Emergency Department Visits and Hospitalizations.

OBJECTIVE: The Certified Community Behavioral Health Clinic (CCBHC) demonstration is designed to increase access to comprehensive ambulatory care and crisis services, which may reduce emergency department (ED) visits and hospitalizations. This study examined whether the demonstration had an impact on ED visits and hospitalizations in Missouri, Oklahoma, and Pennsylvania. METHODS: This difference-in-differences analysis used Medicaid claims data from 2015 to 2019 to examine service use during a 12-month baseline period and the first 24 months of the demonstration for beneficiaries who received care from CCBHCs and beneficiaries who received care from other behavioral health clinics in the same state, representing care as usual. Propensity score methods were used to develop treatment and comparison groups with similar characteristics. RESULTS: In Pennsylvania and Oklahoma, beneficiaries who received care from CCBHCs had a statistically significant reduction in the average number of behavioral health ED visits, relative to the comparison group (13% and 11% reductions, respectively); no impact on ED visits in Missouri was observed. The demonstration was associated with a statistically significant reduction in all-cause hospitalizations in Oklahoma, when the analysis used a 2-year rather than a 1-year baseline period, and also in Pennsylvania, when hospitalizations were truncated at the 98th percentile to exclude beneficiaries with outlier hospitalization rates. CONCLUSIONS: The CCBHC demonstration reduced behavioral health ED visits in two states, and the study also revealed some evidence of reductions in hospitalizations.

Differences in Services Offered by Certified Community Behavioral Health Clinics and Community Mental Health Centers.

OBJECTIVE: This study examined differences between certified community behavioral health clinics (CCBHCs) and community mental health centers (CMHCs) in the services offered and populations served. METHODS: Data from the 2020 National Mental Health Services Survey were used to quantify the proportion of CCBHCs (N=336) and CMHCs (N=1,953) that offered services and served populations described in the CCBHC certification criteria. RESULTS: A higher proportion of CCBHCs than CMHCs offered crisis services, peer support, substance use disorder treatment, treatment for co-occurring disorders, antipsychotics, assertive community treatment, general medical health screening, tobacco cessation services, psychiatric rehabilitation services, and other outpatient services. A higher proportion of CCBHCs than CMHCs served veterans and transition-age youths. CONCLUSIONS: CCBHCs differed from CMHCs in the services provided and populations served. Differences between CCBHCs and CMHCs in some service categories were more pronounced in demonstration than in nondemonstration states. However, it was unclear whether these differences existed before the introduction of the CCBHC model.
