OBJECTIVES:  Care management entity (CME) model is a coordinated, intensive, short-term care delivery model that improves functional outcomes symptoms among youth with serious emotional and behavioral disorders. Few studies have examined clinical outcomes after youth are discharged from CME care and the sustainability of this care intervention is unclear. The study objective was to examine the association between receiving CME care and mental health outcomes one-year post discharge. METHODS:  Data from CME administrative claims were linked with Medicaid claims for youth enrolled in CME anytime from December 2009 through December 2013. Inverse probability treatment weighting (IPTW) was used to balance baseline characteristics between CME-enrolled youth and a non-CME comparison group. Study outcomes were psychiatric inpatient and emergency department (ED) visits one-year following CME discharge. A two-part model was used where the first part modeled the probability of any psychiatric service and the second part modeled the number of visits for each outcome. RESULTS: A total of 2,381 IPTW-adjusted study cohort (488 CME and 1,893 non-CME youth) was identified. In part 1 of the two-part model, the impact of CME care was associated with a significantly lower likelihood of any use of the psychiatric service (any psychiatric ED visit: OR=0.65, p=0.017; any psychiatric hospitalization OR= 0.60, p=0.011). In part 2, no significant differences were observed between the CME care model and number of psychiatric ED visits or hospitalizations. CONCLUSIONS: Reduced psychiatric inpatient and ED services following CME care could be sustainable after youth are discharged from the model. Coordinated, high quality services may have prevented subsequent intensive service needs. Further multi-agency collaboration will be needed to enrich the ability to assess outcomes in broader perspectives.
