Impact of risperidone long-acting injectable on hospitalisation and medication use in Canadian patients with schizophrenia
Bibliographic record
Abstract
SummaryA retrospective chart review was used to assess hospitalisation and medication switching in patients with schizophrenia initiated on either intramuscular risperidone long-acting injectable (RLAI) (n=69) or oral atypical antipsychotics (n=93) in Canada.In the RLAI-treated patients, compared with an identical period prior to RLAI use (40.8 months), there were significant decreases in hospitalisation (50.7 vs. 4.3%; p<0.0001) and duration of hospitalisation (23.5 vs. 0.3 days per patient; p<0.0001) when patients were switched to RLAI (mean treatment period 41.5 months). Compared with patients receiving oral atypicals for 57.2 months, RLAI patients had a reduced risk of hospitalisation (95% confidence interval 1.8–16.5% vs. 54.7–76.4%) and medication switching (95% confidence interval 34.6–58.4% vs. 55.7–76.4%).By virtue of its periodic intramuscular administration, RLAI offers the efficacy and tolerability of an atypical medication without the compliance issues associated with oral drugs, and leads to significant decreases in hospitalisation.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
