Information on prescriber and clinical practice characteristics, LAI prescribing, patient outcomes, and attitudes toward COVID-19 vaccination was collected and described.Results: Of the 401 LAI prescribers meeting survey criteria, 64.6% reported that LAI prescribing remained unchanged (increase: 19.2%, decrease: 14.0%). The majority did not switch patients from LAIs to oral antipsychotics (OAP; 63.3%) or to LAI formulations with lower frequency of administration (68.1%); most prescribers switched the same number of patients from OAPs to LAIs during the pandemic as in previous practice (65.1%). Half of LAI prescribers (50.1%) reported antipsychotic adherence as unchanged among most patients; 44.6% reported symptom control/relapse frequency as unchanged. Most prescribers believed their patients with schizophrenia should be prioritized for COVID-19 vaccination (74.1%) and encouraged all patients to obtain a COVID-19 vaccine (84.0%). However, 64.1% of prescribers reported hesitancy among some patients about vaccines’ safety; 51.4% reported that some patients were willing to be vaccinated despite the hesitancy, 48.6% indicated that some patients perceived COVID-19 vaccines as safe, effective, and important.Conclusion: LAI prescribing and prescriber-reported antipsychotic adherence in patients with schizophrenia remained largely unchanged approximately one year after the start of COVID-19. Focused efforts to overcome patients’ COVID-19 vaccine hesitancy are warranted.Keywords: adherence, antipsychotics, COVID-19, physician survey, prescribing habits, schizophrenia
