Trainee-relevant key performance indicators (KPIs) in colonoscopy (extrapolated from the UK quality standards document by Rees et al)3
| KPIs | Minimal standards |
| Unassisted caecal intubation rate (CIR) | >90% |
| Rectal retroversion | >90% |
| Adenoma detection rate* | >15% |
| Polyp retrieval rate | >90% |
| Patient’s comfort | <10% mod-severe discomfort |
This excludes KPIs which may be primarily influenced by the trainer, for example, sedation doses, withdrawal time, adenoma detection rate.
*Polyp detection rate may be used as a substitute.
