Effect of Intervention for Colonoscopy Quality is Associated With the Personal Characteristics
Study Details
Study Description
Brief Summary
This study aims to investigate whether the personal characteristics of the endoscopist is associated with effect of interventions for colonoscopy quality improvement.
This is a prospective, 9-month, multicenter, single-blind study. Baseline quality indicators including adenoma detection rate, polyp detection rate, withdrawal time and adenomas per colonoscopy of each endoscopist were measured in the health promotion centers of academic hospitals for 3 months. Follow-up measurements of quality indicators were repeated every 3 months after each interventions (personal notification of quality indicators, open notification of quality indicators, and colonoscopy quality education by a GI faculty. At the end of the study, personal characteristics of each endoscopist was evaluated using fear of negative evaluation scale, cognitive flexibility inventory, and almost perfect scale.

Detailed Description
Suboptimal colonoscopy quality is associated with development of interval colorectal cancer and colorectal cancer-related death. It is uncertain how to improve colonoscopy quality effectively. The quality of screening colonoscopy for colorectal cancer depends on the endoscopist who performed the examination. The aim of this study was to investigate the impact of endoscopists' personal characteristics on the quality of colonoscopy and effectiveness of intervention.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Endoscopist Intervention for personal notification, open notification and colonoscopy quality education by a GI faculty |
Behavioral: Personal notification
Baseline quality indicators of each endoscopist were measured and those were notified individually.
Behavioral: Open notification
Quality indicators were measured for 3 months after 1st interventions and those were notified openly
Behavioral: Education
Quality indicators were measured for 3 months after 2nd interventions and educated the importance of colonoscopy quality by a GI faculty
