The Role of Afro-Canadian Status in Police or Ambulance Referral to Emergency Psychiatric Services
Bibliographic record
Abstract
OBJECTIVE: This study tested the hypothesis that among patients admitted to a hospital with psychosis, Afro-Canadian patients would be more likely than Euro-Canadian or Asian-Canadian patients to be brought to emergency services by police or ambulance. METHODS: Data on psychotic patients admitted to the psychiatry ward in 1999 were extracted from records of a general hospital in Montreal. Logistic regression models examined the relationship between being Afro-Canadian and being brought to the emergency service by police or ambulance, while controlling for age, gender, marital status, and number of psychotic symptoms. RESULTS: Of the 351 patients with psychosis, 59 percent were Euro-Canadian, 11 percent were Afro-Canadian, and 18 percent were Asian Canadian. Most Afro-Canadian patients in the study were immigrants from the Caribbean and Africa. Being Afro-Canadian was independently and positively associated with police or ambulance referral to emergency services. CONCLUSIONS: Afro-Canadians admitted to the hospital with psychosis are overrepresented in police and ambulance referrals to emergency psychiatric services.

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.
