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.
|Condition or disease||Intervention/treatment||Phase|
|Serrated Polyp Colorectal Neoplasms||Other: Educational intervention (oral presentation)||Not Applicable|
|Study Type :||Interventional (Clinical Trial)|
|Actual Enrollment :||138 participants|
|Intervention Model:||Parallel Assignment|
|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.|
|Masking:||None (Open Label)|
|Masking Description:||The investigator personally delivers the training and can thus not be blinded for the endoscopists allocated to the intervention-arm.|
|Primary Purpose:||Health Services Research|
|Official Title:||The Influence of a Short Training in the Detection Rate of Proximal Serrated Polyps in an Asymptomatic Patient Population|
|Actual Study Start Date :||January 1, 2014|

All endoscopists employed by 9 semi-randomly chosen hospitals in the Netherlands will be exposed to an educational intervention (oral presentation): an oral awareness training which will be delivered twice, first in 2014 and then in 2016/2017.
In total 38 endoscopists are included from these 9 hospitals.
Other: Educational intervention (oral presentation)
A brief oral presentation (30-45 minutes) which focused on making endoscopists aware of the significance and characteristics of serrated polyps.
No Intervention: Control arm
A random set of 100 endoscopists will be selected ass a reference group. These 100 endoscopists were unaware of the present study, and were thus blinded for their allocation.
- Proximal serrated polyp detection rate (PSPDR) [ Time Frame: Up to five years (between 2014 and 2018) ]Rate/proportion of an endoscopist's colonoscopies with one or more serrated polyps proximal to or in splenic flexure.
- Adenoma detection rate (ADR) [ Time Frame: Up to five years (between 2014 and 2018) ]Rate/proportion of an endoscopist's colonoscopies with one or more adenomas
