Development of Quality Indicators and Quality Improvement Plan of Colonoscopy in Experienced Endoscopist

April 14, 2016 updated by: Su Jin Chung, Seoul National University Hospital

Seoul National University Hospital Healthcare System Gangnam Center Colonoscopy Quality Upgrade Project (Gangnam-CUP): Development of Quality Indicators and Quality Improvement Plan of Colonoscopy in Experienced Endoscopist.

The purpose of this study is to determine clinical factors affecting quality indicators of colonoscopy including adenoma detection rate, and whether quality of colonoscopy could be elevated by improving related factors.

Detailed Description

This study is an extension of quality assurance program in Seoul National University Hospital Healthcare System Gangnam Center. This study is composed of five periods. First, quality indicators of colonoscopy in experienced endoscopists will be analyzed retrospectively from January 2011 to december 2014. Individual differences and changes of quality indicators in every endoscopist will be verified. In second period, from January 2015 to March 2015, quality assurance program will be activated. Endoscopists will be educated by EQUIP (Endoscopic Quality Improvement Program). Also split-regimen bowel preparation instead of same-day regimen and Boston bowel preparation scale will be introduced to standardize disparity of grading. Third, prospective trial starts from April 2015 to March 2018. All endoscopists will receive feedbacks of their own adenoma detection rates in every 3 months. Changes of quality indicators for each endoscopist will be investigated, and annually monitored by institutional review board. If there is a significant improvement of quality indicators in interim assessment, prospective trial will be extended until April 2018. Fourth is wash-out period from April 2018 to march 2019. Feedbacks will be stopped and adenoma detection rates and quality indicators of endoscopists will be compared with those from prospective period. Finally, cumulative rate and mortality rate of colorectal cancers will be investigated until December 2019.
