Measuring colposcopy quality in Canada: development of population-based indicators

Area of Science:

• Gynecologic Oncology
• Public Health Surveillance
• Quality Improvement in Healthcare

Background:

• Colposcopy is a critical component of cervical cancer control strategies.
• Evolving screening and prevention methods necessitate robust monitoring of colposcopy performance.
• Population-based quality indicators are essential for evaluating colposcopy services within Canadian screening programs.

Purpose of the Study:

• To identify and recommend population-based colposcopy quality indicators for ongoing measurement by Canadian cervical cancer screening programs.
• To establish a standardized framework for assessing colposcopy quality across Canada.

Main Methods:

• A multidisciplinary expert working group convened by the Pan-Canadian Cervical Cancer Screening Network identified indicators.
• A systematic literature review was performed to find existing population and program-level indicators.
• A prioritization matrix and a systems-level pathway analysis were used to select and refine key indicators.

Main Results:

• Ten priority population-based colposcopy quality indicators were identified, including uptake, histologic investigation rates, referral rates, and treatment proportions.
• Two descriptive indicators, colposcopist volume and density, were also identified.
• Specific indicators address treatment frequency in young women and biopsy rates after low-grade Pap tests.

Conclusions:

• High-quality colposcopy services are fundamental to effective provincial cervical cancer screening programs.
• The proposed quality and descriptive indicators will enable comparative analysis of colposcopy outcomes across Canadian provinces.
• These indicators will facilitate the identification of areas for improvement in colposcopy service delivery nationwide.
