What this research studies

From a patient's perspective, researchers use health records and pooled data from the FEP-CAUSAL Collaboration to compare outcomes after starting oral antipsychotics versus long-acting injectable formulations. They aim to mimic randomized trials by selecting comparable patient groups and using statistical methods to reduce bias. The team will benchmark their findings against two major trials (EUFEST and PRELAPSE) to increase confidence in observational results. Outcomes studied include medication adherence, relapse, and hospitalizations for adolescents and adults.

Who could benefit from this research

Good fit: Ideal candidates are people (including adolescents and young adults) who have experienced a first episode of psychosis and who are starting or considering antipsychotic treatment.

Not a fit: People without psychotic disorders, those with long-standing chronic psychosis well past their first episode, or individuals not treated with antipsychotics are unlikely to directly benefit from participation.

Why it matters

Potential benefit: If successful, this work could clarify which medications and delivery methods reduce relapse and hospital stays for people after a first psychotic episode.

How similar studies have performed: Large randomized trials like EUFEST and PRELAPSE have shown important results for first-episode psychosis, and this project uses observational methods to extend and complement those findings.
