Prescribing practices in a population-based HIV postexposure prophylaxis program
Bibliographic record
Abstract
OBJECTIVES: To characterize factors associated with being prescribed triple or double postexposure prophylaxis (PEP) against HIV in a population-based program. METHODS: Individuals potentially exposed to HIV received a 5 day starter kit of either double or triple antiretroviral PEP between April 1999 and November 2000 and did/did not receive the remaining 23 days PEP. Data were collected through dispensation of kits. Logistic regression identified characteristics independently associated with being prescribed triple therapy starter kits and with any 23 day follow-up. RESULTS: Of 2064 people receiving 5 day PEP [403 (20%) triple and 1661 (80%) double], 590 (29%) received 23 day follow-up. Independently associated with being prescribed triple therapy starter kits were being male [adjusted odds ratio (AOR) 1.38; 95% confidence interval (CI) 1.10-1.74; P = 0.006), occupational mucocutaneous injuries (AOR 1.70; 95% CI, 1.14-2.55; P = 0.010), and community needlesticks (AOR 2.04; 95% CI, 1.54-2.69; P < 0.001). Independently associated with being prescribed the 23 day follow-up were being male (AOR 1.24; 95% CI, 1.00-1.53; P = 0.04), community mucocutaneous incidents (AOR 2.83; 95% CI, 1.41-5.70; P = 0.004), community needlesticks (AOR 1.75; 95% CI, 1.33-2.29; P < 0.001), and having received triple therapy as the starter kit (AOR 2.61; 95% CI, 2.07-3.29; P < 0.001). CONCLUSIONS: Being prescribed triple therapy starter PEP was associated with being male and with experiencing an occupational mucocutaneous or community needlestick injury. Receiving the remaining 23 days PEP was associated with being male, experiencing a community mucocutaneous or needlestick injury, and triple therapy as the initial 5 day starter PEP.

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.
