Clozapine Treatment in Patients with Prior Substance Abuse
Bibliographic record
Abstract
OBJECTIVE: This study examined outcomes following discharge on clozapine for treatment-resistant schizophrenia patients with and without diagnosed substance abuse histories. METHODS: Those discharged on clozapine from a research unit between April 1991 and March 1996 were followed with respect to hospitalization status. Of the treatment-resistant patients with schizophrenia, 19 were diagnosed as individuals with substance abuse, while 26 patients had no history of abuse. Patients were openly treated with clozapine and were included in the study if they were stabilized and discharged on the medication. RESULTS: Patients who had histories of abuse exhibited a better treatment response and a lower total Brief Psychiatric Rating Scale (BPRS) score at discharge, compared with the non-substance abuse group. One-year readmission rates were 21% and 23% in patients with and without prior substance abuse histories, respectively (P = ns). CONCLUSIONS: Clozapine may be a therapeutic option for the dually diagnosed population and may offer benefits to patients with schizophrenia who have a history of substance abuse.

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.
