Abstract
Introduction and Objective: Benign prostatic hyperplasia (BPH) is one of the most common urological complaints encountered by general practitioners (GPs). 5--reductase inhibitors (5-ARI) are new synthetic agents currently used in its management. We sought to investigate practice patterns, indications for urological consultations and level of awareness by GPs who treat patients with 5-ARIs. Materials and Methods: We conducted a survey which was mailed in both French and English to over 8000 registered GPs in Quebec. The questions covered each physician's BPH patient load, their preferred management plans for BPH, their knowledge of and comfort with 5-ARI, the type of 5-ARI they most often prescribed and clinical scenarios related to their use, when to refer to a urologist, and their role in prostate cancer chemoprevention. Results: Of the surveys mailed, 520 (6.5% response rate) were returned. Mean years from graduation was 24.8 (median 25, range 3-58) years with more than 90% of responders indicating they see less than 20 patients per week with BPH and 1-5 new consults for lower urinary tract symptoms. Overall, 34.1% of GPs initiated 5-ARI therapy themselves while the rest were renewals initiated by the urologist. Among GPs, 20% and 12% use 5-ARI alone and in combination as first-line therapy for BPH. Once on therapy, 73% do not refer to urology if PSA does not decline after 6-12 months of 5-ARI treatment. Only 7% correlated 5-ARI with more aggressive prostate cancer. Interestingly, 39.1% would not advocate its use in chemoprevention for prostate cancer in asymptomatic patients regardless of the percent risk reduction. Conclusion: There still is a preference among GPs to use -blockers over 5-ARI in the management of BPH as well as a hesitancy to use them as preventative measures for prostate cancer. Importantly, there is a lack of awareness of the effect of 5-ARIs on PSA kinetics and reluctance to refer to a urologist in the face of stable borderline PSA despite 5-ARI therapy. Further education among GPs needs to be instilled about these drugs in order to safely optimize their usage at the primary care level and to avoid delays in cancer detection.

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.
