Monitoring photographic proof of cecal intubation: A closed-loop audit of best practice colonoscopy

Gold standard colonoscopy in the UK demands a 90% cecal intubation (CI) rate. Endoscopists must provide photographic evidence of CI, which can include images of the terminal ileum, appendix orifice, anastomosis or ileocecal valve. Whilst photographic proof of intubation should be obtained for all complete colonoscopies, this is not routinely audited. Three hundred and ninety-six complete colonoscopies were analyzed, 200 in an initial audit, and 196 in a second audit. Photos taken during colonoscopy were reviewed for evidence of successful CI, as well as whether these photographs had been marked as “proof of intubation” (POI). Results were shared at departmental governance meetings in order to assess any improvement in practice. Initial audit revealed 70% of colonoscopies had provided sufficient proof of CI but only 50% provided photographs that were described as such. Twenty percent of colonoscopies provided sufficient images, but these were not identified as POI. Thirty percent of all colonoscopies provided insufficient proof of CI. Upon repeat audit, 71% of colonoscopies met best practice standards, with the remaining 29% showing insufficient evidence of CI. In the modern era of digital technology, lack of photographic evidence should be seen as unacceptable and may raise important clinical and medicolegal concerns. We recommend that audits such as this become standard practice to ensure best practice.
