Increasing Serrated Polyp Detection With a Brief Awareness Training

Not Applicable

Completed

• Conditions: Serrated Polyp; Colorectal Neoplasms
• Interventions: Other: Educational intervention (oral presentation)

• Registration Number: NCT03902899
• Lead Sponsor: Academisch Medisch Centrum - Universiteit van Amsterdam (AMC-UvA)

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.

Arm && Interventions

Group	Intervention	Description
Intervention-arm	Educational intervention (oral presentation)	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.

Primary Outcome Measures

Name	Time	Method
Proximal serrated polyp detection rate (PSPDR)	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.

Secondary Outcome Measures

Name	Time	Method
Adenoma detection rate (ADR)	Up to five years (between 2014 and 2018)	Rate/proportion of an endoscopist's colonoscopies with one or more adenomas
