Readmissions, costs, and duration to subsequent outpatient visit after hospital discharge among Medicaid beneficiaries utilizing oral versus long-acting injectable antipsychotics in bipolar disorder or schizophrenia.

This study compared long-acting antipsychotics that were administered by injection (LAIs) to antipsychotic agents taken orally (OAPs) among Medicaid members with bipolar disorder and/or schizophrenia. Readmission to the emergency department (ED) or hospital (within 30 days of a previous visit) and costs were observed to be similar with LAIs relative to OAPs. Among members who went to the hospital, a shorter time to psychiatric follow-up outpatient visit and lower costs were observed among those taking LAIs relative to OAPs.
