Ability of a rapid HIV testing site to attract and test vulnerable populations: a cross-sectional study on Actuel sur Rue
Bibliographic record
Abstract
Quebec's HIV epidemic persists, particularly among men who have sex with men (MSM) and in Montreal. Increasing access to HIV testing is necessary and community-based rapid testing offers one strategy. This paper examines the clienteles and activities of a rapid HIV testing site in Montreal, the pilot project Actuel sur Rue. Comparative analyses were conducted with 1357 MSM, 147 heterosexual men and 64 women who visited Actuel sur Rue between July 2012 and November 2013 on socio-demographics, health, drug use, sexual practices/infection and HIV testing/prevention. Significant group differences were observed in each category. Actuel sur Rue received 1901 clients, conducted 1417 rapid HIV tests and tested 77 never-tested individuals. Rapid testing produced a high reactive rate (2%). Only 1/28 of those with reactive tests had no previous HIV testing, and 36% had used post-exposure prophylaxis, suggesting missed opportunities for prevention. Findings highlight diverse client vulnerability profiles and the relevance of checkpoints and further prevention efforts.

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.
