Overview

This retrospective study shows the rate of timely follow-up colonoscopy in an older population, indicating the need for system-level improvements.

Key Points

  • To assess the rates and timing of follow-up colonoscopy after positive stool-based tests in a health system.
  • Analyzed a cohort of 701 patients aged 45-75 with positive stool tests.
  • Evaluated rates of timely follow-up colonoscopy within 90, 180, and 365 days.
  • Conducted multivariable Cox proportional hazard models to identify influencing factors.
  • Used Pareto analysis to identify barriers to timely colonoscopy.
  • The timely follow-up colonoscopy rate was 59.6%.
  • Only 44.5% completed colonoscopy within 90 days, and 68.5% within a year.
  • Patient outreach increased timely colonoscopy by 52%.
  • Common barriers included lack of gastroenterology visits, patient refusal, and cancellations.
