Clinical Trial Summary

The purpose of this study is to assess the impact of multilevel factors on the quality of screening colonoscopy, reflected mainly by adenoma detection rate (ADR).

Description:

The subjects will include patients who need to screening colonoscopies by 21 endoscopists between January 2019 and December 2019 were retrospectively enrolled in this unit. Multilevel factors, including patient-, proceduralist-, and procedure-level characteristics were analyzed for the relationship with ADR.
