Abstract
Background: Patients treated in early intervention for psychosis programs have better treatment outcomes and higher rates of long-acting injection (LAI) antipsychotic medication utilization (20%-50%) versus treatment as usual. These programs usually serve patients for 2-3 years, then most patients are discharged to other mental health services and studies of patients with longer-standing schizophrenia suggest switching to oral medications may be common. However, following patients post-discharge is complicated by the challenges of migrated patient records across clinical services and providers. Objectives: To examine whether LAI use continues after discharge from an early intervention service for psychosis. Design: This study was a retrospective cohort study examining the effects of continuation or discontinuation of LAI therapy in individuals who have completed treatment in an early intervention service (EIS) for psychosis. Methods: A retrospective cohort was created from a group of individuals discharged from EIS for psychosis over a 3-year period from January 1, 2016 to December 31, 2018 and followed for mental health outcomes and antipsychotic medications prescribed for a subsequent 2-year period at discharge, 6, 12, 18, and 24 months post-discharge. Results: Of 85 subjects discharged from three sites in three different provinces in Canada for whom full follow-up could be recorded, 60 subjects remained on LAI medications after 24 months (71%). The average age of the cohort was 22 years (SD 4.7) at admission to an EIS. At discharge, the most commonly used LAI was aripiprazole, and most subjects were maintained on the same formulation at 24 months, if still on LAI. Reasons for discontinuation were predominantly patient preference. Significant differences in clinical outcomes, measured through reduced rehospitalization were seen for those who remained on LAI as compared to those who did not. Conclusion: LAI adherence is still strong 24 months after discharge from an EIS for psychosis.

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.
