Background:~Approximately 4,600 persons get colon cancer annually in Denmark and it is the second most common cause of cancer death. Survival is highly dependent on early detection through a colonoscopy. A thorough colonoscopy is essential to detect early cancers but unfortunately the quality of colonoscopies varies widely between operators. A study of 314,872 colonoscopies performed by 136 gastroenterologists found that the adenoma detection rate (ADR) ranged from 7 - 53% and was inversely associated with the risks of fatal interval cancer. The investigators have developed to tools that can generate automatic, computerized feedback in order to make a more thorough procedure and reduce patient discomfort, the Colonoscopy Progression Score (CoPS) and Colonoscopy Retraction Score (CoRS)~Objectives:~The investigators predict that live-feedback from CoPS and CoRS doing a colonoscopy can improve the ADR and subsequent prevent colorectal cancer. The aim of this project is to:~In a cluster-randomized study compare if feedback from CoPS and CoRS can improve the adenoma detection rate and patient satisfaction for individual operators and the department as a whole.~Make an immediate measure to assess the quality of individual colonoscopy performance.~Materials and methodology:~As a randomized controlled cluster trial following a stepped-wedge program, feedback doing a colonoscopy from these (CoPS and CoRS) will be tested compared to no feedback. Three test departments consisting of three University Hospital in the Capital region of Denmark will be included.
In a cluster-randomized study compare if feedback from two computerized feedback systems doing a colonoscopy (CoPS and CoRS) can improve the adenoma detection rate and decrease patient discomfort.
