Colorectal Neoplasms, Serrated Polyp
Conditions
Brief summary
In this non-randomized controlled trial, a semi-random group of Dutch endoscopist receive an oral training about the significance of serrated polyps. The primary aim of this training is to improve the endoscopist's awareness of the significance of serrated polyps, ultimately leading to increased detection. In addition, a random group of endoscopists that will not receive this training will be used as a reference group. Data will be collected as part of routine care within the Nationwide Dutch Bowel cancer screening program. The serrated polyp detectionrate of each endoscopist will be extracted from anonymized data that will be prospectively collected as part of routine care within the Dutch Nationwide bowel cancer screening program. Data will be anonymized and provided by Rijksinstituut voor Volksgezondheid en Milieu (RIVM) and ScreenIT.

Masking description
The investigator personally delivers the training and can thus not be blinded for the endoscopists allocated to the intervention-arm.
Intervention model description
This is a non-randomized controlled trial with two arms. The intervention-arm consists of all endoscopists employed by 9 semi-randomly chosen Dutch hospitals hospitals who receive an educational training. The control-arm consists of a specific number of randomly chosen endoscopists.
