Post-discharge Health Services Use for Patients with Serious Mental Illness Treated at an Emergency Department Versus a Dedicated Community Mental Health Center.

Emergency Medical Service (EMS) alternative destination programs may lead to improved care quality among those experiencing mental health crises but the association with cost and emergency department (ED) recidivism remains unexamined. We compare rates of post-discharge health services use and Medicaid spending among patients transported to an ED or community mental health center (CMHC) finding higher ED recidivism for patient treated in the ED, compared to those treated in a CMHC (68% vs 34%, p < 0.001). There were no differences in Medicaid spending or health services use post-discharge suggesting EMS-operated alternative destination programs may be cost-neutral for Medicaid programs.
