Abstract:
Objective:To evaluate the intelligent performance measurement system for colonoscopy.Methods:Nine endoscopists from Renmin Hospital of Wuhan University were randomly assigned to the quality control group and the control group based on inclusion and exclusion criteria by the random number table. In the pre-quality-control stage (from April 20, 2019 to May 30, 2019), colonoscopic data acquired by the enrolled endoscopists were collected. In the training stage (June 1-30, 2019), the quality control group was trained on the quality control knowledge and the use of intelligent gastrointestinal endoscopy performance measurement system; but the control group was only trained on the quality control knowledge.In the post-quality-control stage (from July 1, 2019 to August 20, 2019), a weekly quality feedback was given to endoscopists of the quality control group, while the endoscopists of the control group had no quality control report.Then, the colonoscopic data acquired by enrolled endoscopists were prospectively collected during the period. The primary endpoint was adenoma detection rate. The secondary endpoints were withdrawal time, polyp detection rate and cecal intubation rate.Results:Four endoscopists were assigned to the quality control group and five to the control group. A total of 1 471 colonoscopic procedures were analyzed. The detection rates of adenoma and polyp in the quality control group increased with feedbacks[13.7% (45/329) VS 7.1% (24/338), χ2=55.796, P<0.001; 48.9% (161/329) VS 40.2% (136/338), χ2=4.071, P=0.044], while there were no significant differences in the control group [9.3% (37/398) VS 9.1% (37/406), χ2=0.329, P=0.566; 33.9% (135/398) VS 33.0% (134/496), χ2=3.616, P=0.057]. The withdrawal time in the quality control group increased with feedbacks[5.9 (3.9, 7.3) min VS 4.1 (2.8, 6.1) min, Z=6.965, P<0.001], while there was no significant difference in this variable in the control group [3.9 (2.7, 6.1) min VS 3.6 (2.6, 5.8) min, Z=1.355, P=0.175]. Conclusion:The intelligent performance measurement system for gastrointestinal endoscopy with feedbacks can monitor and improve the colonoscopic quality.
