Introduction Aripiprazole once monthly 400mg (AOM400) is a long-acting injectable (LAI) available as a two-injection start initiation regimen (AOM400-TIS) for the maintenance treatment of adult patients with schizophrenia stabilised with oral aripiprazole. Objectives This survey sought to explore HCPs’ perspectives and attitudes towards prescribing and/or administering AOM400-TIS according to the European label in clinical practice (including reasons for its use, potential benefits, and common barriers and/or concerns) across Europe. Methods HCPs who had prescribed and/or administered the AOM400-TIS regimen to ≥3 patients with schizophrenia were invited to participate in an online survey. The survey was launched in two waves across the target countries (wave 1: Italy, Germany, United Kingdom; wave 2: Denmark, Italy, Sweden). Analysis was descriptive; data was collected between February 1–March 21, 2024 (wave 1) and September 16-October 28 (wave 2). Data from Italian HCPs are presented. Results 31 HCPs from the 1st wave and 64 from the 2nd wave completed the survey including psychiatrists (69%), psychiatric nurses (23%), community nurses (4%) and general practitioners/primary care practitioners (1%). HCPs estimated 30.0% (median; IQR: 20.0–50.0) of patients in their caseload were diagnosed with schizophrenia, and of these, 45.0% were treated with LAIs (median; IQR: 25.0–62.5). 47% of HCPs were primarily responsible for prescribing AOM400-TIS, 24% for administering it, and 28% were responsible for both. HCPs estimated that 44% of patients typically spent up to 14 days on oral aripiprazole prior to AOM400-TIS, with HCPs rating the severity of symptoms of patients initiated with AOM400-TIS as mild (22% of HCPs), moderate (68% of HCPs) and severe (40% of HCPs). The most common reasons for initiating AOM400-TIS after transitioning from oral aripiprazole were poor adherence (80%) and patient preference (49%), and the most reported goals for prescribing AOM400-TIS were to improve adherence (75%) and prevent relapses (69%). Common barriers to the use of AOM400-TIS were patient reluctance to receive two injections (39%), concerns about tolerability (24%), safety of administering a high dose in a single day (23%). Prior treatment adherence (54%) and efficacy (46%) were the most cited factors influencing prescribing of AOM400-TIS. Overall, HCPs “agreed”, or “strongly agreed”, that AOM400-TIS was easy to administer (81%) and that it had a similar safety/tolerability profile to the single injection start regimen (69%), while the majority were satisfied with patient outcomes with AOM400-TIS (83%). Conclusions Overall, Italian HCPs with experience of using AOM400-TIS reported that it is easy to administer, well tolerated and improves treatment outcomes, while barriers to its use include patient reluctance and perceived safety concerns.
