Results Some 88 013 patients who were FIT positive complied with colonoscopy (males: 56.1%; aged 50–59 years: 49.1%) while 23 410 did not (males: 54.6%; aged 50–59 years: 44.9%).
The 10-year cumulative incidence of CRC was 44.7 per 1000 (95% CI, 43.1 to 46.3) among colonoscopy compliers and 54.3 per 1000 (95% CI, 49.9 to 58.7) in non-compliers, while the cumulative mortality for CRC was 6.8 per 1000 (95% CI, 5.9 to 7.6) and 16.0 per 1000 (95% CI, 13.1 to 18.9), respectively. The risk of dying of CRC among non-compliers was 103% higher than among compliers (adjusted HR, 2.03; 95% CI, 1.68 to 2.44).
Conclusion The excess risk of CRC death among those not completing colonoscopy after a positive faecal occult blood test should prompt screening programmes to adopt effective interventions to increase compliance in this high-risk population.Non-compliance with colonoscopy after a positive faecal immunochemical test doubles the risk of dying from colorectal cancer — https://gut.bmj.com/content/early/2021/03/30/gutjnl-2020-322192?rss=1
Help me understand human behavior. You get a positive FOBT or Cologuard test and your doctor says you need a colonoscopy but you decide not to follow up and follow through with the scope.
