The aging male population and medical care for benign prostatic hyperplasia in Canada
Bibliographic record
Abstract
Background: The male Canadian population is aging and more menwill be seeking medical care for benign prostatic hyperplasia (BPH).We examined the projected increase in older Canadian males between2005 and 2018 to evaluate urologic health-care needs.Methods: We used Statistics Canada population projections toderive predictions of the male population aged 50 or more from2005 to 2018 and results from the Olmsted County Study of UrinarySymptoms to estimate numbers of males aged ≥50 with moderateto severe lower urinary tract symptoms (msLUTS) in the sameperiod. Data from the Canadian Institute for Health Informationwere used to estimate the number of urologists in 2018.Results: The number of Canadian men aged ≥50 is projected torise between 2005 and 2018 by 39.5% and the number withmsLUTS by 41.3%. However, the number of practicing urologistsin Canada in 2018 is likely to be similar to the 584 practicing in2007. An increase in the number of urologists proportional to theincrease in men aged ≥50 with msLUTS would require 799 urologistsin 2018.Interpretation: Little opportunity exists to expand the number of traineesin urology. Other alternatives must be sought to deal with increasednumbers of older men with msLUTS. Initial management of BPHhas moved towards being a responsibility of primary care physicians,but they appear to view BPH as a quality-of-life issue. It iscrucial that urologists work closely with primary care physicians toensure that the management of LUTS progression is optimized.Introduction : La population masculine canadienne vieillit, et deplus en plus d’hommes consulteront un médecin en raison d’unehyperplasie bénigne de la prostate (HBP). Nous avons étudié levieillissement prévu de cette population entre 2005 et 2018 afind’évaluer les besoins en soins urologiques.Méthodologie : À l’aide des projections démographiques de StatistiqueCanada, nous avons formulé des prévisions quant à la populationmasculine de 50 ans et plus entre 2005 et 2018; les résultatsde l’étude du comté d’Olmsted sur les symptômes urinaires nousont permis d’évaluer le nombre d’hommes de 50 ans et plus quidevraient présenter des symptômes modérés ou graves touchantles voies urinaires inférieures pendant la même période. Desdonnées de l’Institut canadien d’information sur la santé ont permisd’évaluer le nombre d’urologues en 2018.Résultats : Le nombre de Canadiens de 50 ans et plus devrait augmenterde 39,5 % entre 2005 et 2018, et le nombre d’hommesprésentant des symptômes modérés ou graves touchant les voiesurinaires inférieures, de 41,3 %. En revanche, le nombre d’urologuespratiquant en 2018 au Canada devrait être semblable aunombre établi en 2007 (soit 584). Pour que la hausse du nombred’urologues soit proportionnelle à la hausse du nombre d’hommesde 50 ans et plus qui présenteront des symptômes modérés ougraves touchant les voies urinaires inférieures, il faudrait que cenombre atteigne 799 en 2018.Conclusion : Il est peu probable que le nombre de médecins sespécialisant en urologie augmente. D’autres solutions doiventdonc être mises de l’avant afin de faire face au nombre croissantd’hommes âgés au prise avec des symptômes modérés ou gravestouchant les voies urinaires inférieures. La prise en charge initialede l’HBP incombe maintenant aux médecins de premiersrecours, mais ces derniers semblent considérer l’HBP comme unproblème de qualité de vie. Il est primordial que les urologuescollaborent étroitement avec les médecins de soins primaires pourassurer une prise en charge optimale des symptômes touchantles voies urinaires inférieures.

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.
