Summary
This summary is machine-generated.

Most sex-specific screening polypectomy rates in Québec fall below quality benchmarks, particularly for individuals aged 50-54. These findings highlight a need to improve colorectal cancer screening effectiveness in the region.

Area of Science:

  • Gastroenterology
  • Public Health
  • Health Services Research

Background:

  • Quality benchmarks for screening polypectomy rates are established at 40% for men and 30% for women.
  • Assessing adherence to these benchmarks is crucial for evaluating the effectiveness of colorectal cancer screening programs.

Purpose of the Study:

  • To estimate and compare sex-specific screening polypectomy rates in Québec against established quality benchmarks.
  • To identify age and sex-specific disparities in screening polypectomy rates.

Main Methods:

  • A prospective cohort study involving 45 endoscopists and 2134 patients aged 50-75 in Québec.
  • Screening indications were collected via patient and endoscopist questionnaires.
  • Sex-specific polypectomy rates and 95% confidence intervals were calculated using Bayesian hierarchical logistic regression.

Main Results:

  • Patient-reported screening polypectomy rates were 32.4% for males and 19.4% for females.
  • Endoscopist-reported rates were 30.2% for males and 16.6% for females.
  • Most sex-specific rates did not meet quality benchmarks, with the exception of certain age groups for males. Patients aged 50-54 had rates significantly below benchmarks.

Conclusions:

  • Screening polypectomy rates in Québec are generally below quality benchmarks for both sexes.
  • Rates were particularly low among individuals aged 50-54, indicating a potential area for targeted improvement in screening practices.
