Services for people at high risk improve outcomes in patients with first episode psychosis.

Abstract

ObjectiveAbout one‐third of patients referred to services for people at high risk for psychosis may have already developed a first episode of psychosis (FEP). We compared clinical outcomes in FEP patients who presented to either high risk or conventional mental health services.MethodRetrospective study comparing duration of hospital admission, referral‐to‐diagnosis time, need for compulsory hospital admission and frequency of admission in patients with FEP who initially presented to a high‐risk service (n = 164) to patients with FEP who initially presented to conventional mental health services (n = 2779). Regression models were performed, controlling for several confounders.Results FEP patients who had presented to a high‐risk service spent 17 fewer days in hospital [95% CI: −33.7 to (−0.3)], had a shorter referral‐to‐diagnosis time [B coefficient −74.5 days, 95% CI: −101.9 to −(47.1)], a lower frequency of admission [IRR: 0.49 (95% CI: 0.39–0.61)] and a lower likelihood of compulsory admission [OR: 0.52 (95% CI: 0.34–0.81)] in the 24 months following referral, as compared to FEP patients who were first diagnosed at conventional services.ConclusionServices for people at high risk for psychosis are associated with better clinical outcomes in patients who are already psychotic.
