Carlos Fernandes et al. Adenoma detection rate by colonoscopy in real-world population-based
studies: a systematic review and meta-analysis
Adenoma detection rate (ADR) is a key quality indicator in colonoscopy; however, data
are often derived from prospective studies for selected indications or randomized
controlled trials. In “real world” practice, indications and patient groups may vary.
This review examined data from outside of carefully controlled studies to estimate
the ADR in direct colonoscopy screening (27%), post-fecal immunochemical testing (34%),
surveillance (43%), diagnostic (25%), and overall (27%) groups. These results suggest
that current society guideline recommendations for a baseline ADR of 25% are appropriate.
