Reach and effectiveness of mailed nicotine replacement therapy for smokers: 6-month outcomes in a naturalistic exploratory study
Bibliographic record
Abstract
BACKGROUND: There are important inequities in smoker access to clinic-based smoking cessation services. Low barrier high-reach interventions are proposed as solutions to these inequities. Although effective, telephone quitlines, which provide multi-session counselling but no medication, have low utilization with high attrition. The objective of this study was to determine the effectiveness of free nicotine replacement therapy (NRT), brief advice and self-help materials on quit attempts and 6-month quit rates in motivated smokers. METHODS: In this open-label naturalistic study, 14,000 treatments of 5 weeks in duration of either nicotine patch (n=10,000) or nicotine gum (n=4000) were made available to all eligible adult smokers in Ontario, Canada, who called a toll-free number to register with the STOP (Smoking Treatment for Ontario Patients) Study and receive a single brief intervention. The primary outcome measure was self-reported abstinence rates at 6 months post-treatment among STOP participants. These data were compared with quit rates that were reported in a concurrent no-intervention cohort of Ontario smokers matched for eligibility. RESULTS: 16 405 callers were assessed and 13143 eligible participants were mailed a treatment package with 5 weeks of NRT (choice of patch or gum), self-help and community resource materials. Among the 6261 participants who consented to follow-up, 2601 (42%) had complete follow-up data. Of those with complete follow-up data, the percentage reporting abstinence after 6 months in the treatment cohort was 21.4%, relative to 11.6% in the no-intervention cohort (rate ratio of 1.84; 95% CI 1.79 to 1.89), with the 30-day point prevalence of 17.8% and 9.8% for the intervention and no-intervention cohorts, respectively (rate ratio 1.81; CI 1.75 to 1.87). CONCLUSIONS: Provision of free NRT by mail following a brief telephone intervention is an effective strategy to reach and assist a large number of smokers making a quit attempt.

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.
