Pregnancy prevention among women taking isotretinoin: failure to comply with the recommendations.
Bibliographic record
Abstract
OBJECTIVE: To assess whether prescribing physicians advised female patients taking isotretinoin according to pregnancy prevention recommendations, whether women understood those recommendations, and whether women complied with recommendations to prevent pregnancy. DESIGN: Cross-sectional study designed to collect patients' self-reported information. Women were interviewed by telephone with a standardized questionnaire. SETTING: Quebec. PARTICIPANTS: Participants were recruited through pharmacies, medical clinics, and newspapers in Quebec. All subjects (45 women 14 years and older) were treated with isotretinoin at the time of the interview or in the preceding 6 months. MAIN OUTCOME MEASURES: Women's self-report of their physician's behaviour regarding prevention of pregnancy, women's comprehension of the information, and their level of compliance with recommendations. RESULTS: Prescribing physicians discussed the risks of teratogenesis with 93% of the women but gave written information to only 36% of them. Seventy-eight percent of the women admitted not using 2 contraceptive methods all the time during the treatment, and 3 women reported having had sexual intercourse without any contraception. Physicians prescribed a pregnancy test before treatment for 44% of the women. Only 18% of the women waited for their next menstrual period to begin isotretinoin treatment, and this advice was given by 20% of physicians. A statistically significant relationship between counseling and recommendations given by physicians and women's use of double contraception was highlighted. CONCLUSION: Female patients reported physicians did not always advise them according to recommendations concerning pregnancy prevention. Women understood the information received but did not fully comply. The extent of pregnancy prevention measures taken by physicians was linked to women's compliance. Further study exploring underlying reasons for women's noncompliance could provide information on changing such behaviour.

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.
