Does an integrated outreach intervention targeting multiple stages of early psychosis improve the identification of individuals at clinical high risk?
Bibliographic record
Abstract
AIMS: To explore the impact of a targeted case identification intervention, with training and education regarding first-episode psychosis and clinical high-risk syndromes, on the referral and identification of those at high risk. METHODS: Using a historical control design, referral information from pre-intervention and post-intervention periods was collected via administrative data and clinician notes from a catchment-based early psychosis service. RESULTS: A significant increase in the number of referrals sent to the service's clinical high-risk unit was observed following the intervention (P = 0.01). The proportion of referrals eligible was significantly higher post-intervention (P = 0.03), with the majority (26/44, 59.1%) referred via the first-episode psychosis service unit. CONCLUSIONS: An integrated outreach intervention for both first-episode psychosis and the clinical high-risk state was effective in increasing referrals of eligible cases to the service's at-risk unit. Rather than being stage-specific, targeted case identification strategies and service integration should span across the early stages of psychosis.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
