Short-term rehospitalizations in young adults with schizophrenia treated with once-monthly paliperidone palmitate or oral atypical antipsychotics: a retrospective analysis
Bibliographic record
Abstract
Objective: To compare rehospitalizations in patients with schizophrenia treated with paliperidone palmitate (PP1M) vs oral atypical antipsychotics (OAAs), with a focus on young adults (18–35 years).Methods: The Premier Healthcare database (January 2009–December 2016) was used to identify hospitalizations of adults (≥18 years) with schizophrenia treated with PP1M or OAA between September 2009 and October 2016 (index hospitalizations). Rehospitalizations were assessed at 30, 60, and 90 days after each index hospitalization in young adults and in all patients. Proportions of index hospitalizations resulting in rehospitalization were reported and compared between groups using odds ratios (ORs) and 95% confidence intervals (CIs).Results: A total of 8578 PP1M and 306,252 OAA index hospitalizations were included. Hospitalized young adults treated with PP1M (n = 3791) were more likely to be seen by a psychiatrist (94.0% vs 90.0%), and had a longer length of stay (12.5 vs 8.6 days) compared to hospitalized young adults treated with OAA (n = 96,502). Following their discharge, young adults receiving PP1M during an index hospitalization had a 25–27% lower odds of rehospitalization within 30, 60, and 90 days compared to young adults receiving OAAs (all p < .001). Similarly, when observing all patients, those receiving PP1M during an index hospitalization had 19–22% lower odds of rehospitalization within 30, 60, and 90 days compared to those receiving OAAs (all p < .001).Conclusions: Following a hospitalization for schizophrenia, PP1M treatment was associated with fewer 90-day rehospitalizations among young adults (18–35 years) relative to OAA treatment. This finding was also observed in other hospitalized adults with schizophrenia.

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.
