Area of Science:

  • Public Health
  • Gastroenterology
  • Health Services Research

Background:

  • Colorectal cancer (CRC) screening is crucial for early detection and improved outcomes.
  • Understanding screening patterns and physician perspectives is vital for optimizing CRC prevention strategies.

Purpose of the Study:

  • To assess CRC screening rates and sociodemographic disparities in Toronto.
  • To explore physicians' views on fecal occult blood testing (FOBT) and colonoscopy for average-risk patients.
  • To identify factors influencing CRC screening method selection.

Main Methods:

  • Mixed-methods approach combining administrative data analysis and physician interviews.
  • Analysis of patient sociodemographic data and CRC screening types.
  • Thematic analysis of semistructured interviews with physicians.

Main Results:

  • Lower CRC screening rates observed in younger, male, lower-income, and immigrant populations.
  • Colonoscopy use was particularly low among lower-income and immigrant patients.
  • Physicians showed divided opinions on FOBT versus colonoscopy, influenced by specialist recommendations and patient expectations.

Conclusions:

  • Significant variations in CRC screening exist across sociodemographic groups.
  • Physician preferences for FOBT or colonoscopy are influenced by systemic factors and patient characteristics.
  • Informed patient choice and potential policy/attitude shifts may enhance screening rates and reduce disparities.
