Conditions

Adenoma Detection Rate, Colonoscopy

Brief 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).

Detailed 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.
