 Introduction Population screening for colorectal cancer was introduced in Denmark in 2014 leading to a substantially increased demand on the endoscopy units, which are typically based in the surgical departments. Colonoscopy can be effective in detecting cancers at an early stage or even preventing cancer by removal of premalignant polyps. A prerequisite for this effect is a high quality endoscopy service with a very low incidence of complications and missed cancers. Another important aspect is compliance within the target population. This is also largely dependent on the quality of colonoscopy including minimal discomfort and the perception of endoscopy staff as competent, knowledgeable, friendly and courteous.
