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.
