This study compared rehospitalization and practice patterns among patients with schizophrenia in the United States prescribed oral antipsychotics (OAs), alone or with long-acting injectable antipsychotics (LAIs) at hospital discharge. Data came from a hospital-based payer database from December 2019-June 2021. At discharge, 23,336 (84 %) patients were prescribed OAs and 4293 (16 %) were prescribed LAIs±OAs (first-generation LAIs±OAs, 2990/4293 [70 %]; second-generation LAIs±OAs, 1303/4293 [30 %]). The most prescribed OA and LAI±OA were risperidone (26 %) and haloperidol (37 %), respectively. Significantly greater proportions of patients were rehospitalized within 30, 60, or 90 days after discharge with OAs (11 %, 15 %, and 18 %, respectively) vs LAIs±OAs (8 %, 12 %, and 15 %; numbers needed to treat [NNTs], 37, 35, and 38), and with first-generation (9 %, 13 %, 16 %) vs second-generation (7 %, 10 %, 13 %) LAIs (p < 0.05 for all). Significantly greater proportions prescribed LAIs dosed once every 2 weeks vs monthly were rehospitalized within 60 days (15 % vs 11 %, respectively; NNT 33) and 90 days (18 % vs 14 %; NNT 26) (p < 0.05 for all). Prescriptions were based on clinical characteristics at discharge; those prescribed LAIs±OAs may have had less favorable prognoses. However, these results suggest that prescribing second-generation LAIs±OAs with less frequent dosing at discharge may lower rehospitalization risk for patients with schizophrenia.
