Background: Individuals presenting with first episode psychosis (FEP) constitute a population with high admission rates. Across psychiatric services, community based treatment is aimed for where appropriate. Therefore, further knowledge on predictors of admission is required.
Purpose: The objectives were to: (i) determine the proportion of individuals with FEP admitted at time of presentation (voluntarily and involuntarily) (ii) identify associated demographic and clinical factors.
Methods: This study included all young people (aged 15-24) who presented with FEP to the Early Psychosis Prevention and Intervention Centre, Melbourne, Australia from 01.01.11 to 31.12.16. Binary logistic regression was used to determine unadjusted and adjusted odds ratios.
Results: Of 1208 participants, 58.6% were male and the median age was 20 years (I.Q.R.17-22). At time of presentation, 50.2% were admitted. On multivariate analysis, the following factors predicted admission: being a migrant (OR = 1.75, 95% CI [1.17, 2.62]), aggression (OR = 1.42, 95% CI [1.02, 1.99]), and more severe psychotic symptoms. Longer duration of untreated psychosis was associated with lower admission rates. 70.1% of admissions were involuntary (33.7% of the cohort). Risk factors for involuntary admission were consistent with any admission, other than aggression, and with the addition of older age and male sex.
Conclusion: There remains a high admission rate for FEP, even in an established early intervention service, with severity of psychopathology being the strongest predictive factor. There is an independent association between migrancy and admission. Potential reasons for these findings are discussed, and initiatives to reduce admission rates including (i) interventions to prevent admission and (ii) alternative care pathways.
