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.

In contrast to prior studies, this real-world investigation noted higher hospitalizations and readmissions among LAIs relative to OAP medications, but among members with a hospitalization or ED visit, LAIs were associated with shorter durations to outpatient visits and lower costs. Those with diagnoses of both BP with SCZ had higher odds of any readmission, number of readmissions, and costs relative to those with bipolar disorder alone and may be a key target for interventions.
