摘要目的:评价智能消化内镜质控系统在胃镜检查中的质量控制作用。方法:将来自武汉大学人民医院的14例内镜医师按随机数字法分配到质控组和对照组。在质控前阶段（2019年4月20日—2019年5月31日），回顾性收集入组内镜医师的胃镜检查资料信息。在质控培训阶段（2019年6月1—30日），质控组内镜医师培训质控相关知识和智能消化内镜质控系统的使用说明；对照组内镜医师仅培训质控相关知识。在质控后阶段（2019年7月1日—2019年8月20日），通过审查和反馈模式，由智能消化内镜质控系统统计质控组内镜医师胃镜检查的质控指标并生成质控报告，每周将质控报告反馈给质控组内镜医师。主要观察质控组和对照组癌前病变检出率的变化。结果:内镜医师被随机分配到质控组和对照组各7例。质控前阶段和质控后阶段共纳入胃镜检查3 446例，其中，质控前阶段1 651例（质控组753例、对照组898例），质控后阶段1 795例（质控组892例、对照组903例）。质控组的癌前病变检出率在质控后提高了3.6%［3.3%（29/892）比6.9%（52/753）， χ2=11.65， P<0.01］，对照组提高了0.4%［3.3%（30/903）比3.7%（33/898）， χ2=0.17， P=0.684］。 结论:智能消化内镜质控系统结合审查和反馈模式可对内镜医师的胃镜检查起质量控制作用，并提高内镜医师的胃镜检查质量。

abstractsObjective:To evaluate the intelligent gastrointestinal endoscopy quality control system in gastroscopy.Methods:Fourteen endoscopists from Renmin Hospital of Wuhan University were assigned to the quality-control group and the control group by the random number table. In the pre-quality-control stage (from April 20, 2019 to May 31, 2019), data of gastroscopies performed by the enrolled endoscopists were collected. In the training stage (June 1 to 30, 2019), the quality-control group was trained in quality control knowledge and the instructions of intelligent gastrointestinal endoscopy quality control system; but the control group was only trained in quality control knowledge. In the post-quality-control stage (from July 1, 2019 to August 20, 2019), a quality report was submitted weekly to the endoscopists in the quality-control group with a review and feedback, while the control group had no quality control report. Simultaneously, the gastroscopies performed by the enrolled endoscopists were collected during the period. Changes of precancerous lesion detection rate in the two groups were compared.Results:Seven endoscopists were assigned to each group. A total of 3 446 gastroscopies were included in the pre-quality-control stage ( n=1 651, including 753 cases in the quality-control group and 898 cases in the control group) and post-quality-control stage (n=1 795, including 892 cases in the quality-control group and 903 cases in the control group). The detection rate of precancerous lesions in the quality-control group increased by 3.6% [3.3% (29/892) VS 6.9% (52/753), χ2=11.65, P<0.01], while that of the control group increased by 0.4% [3.3% (30/903) VS 3.7% (33/898), χ2=0.17, P=0.684]. Conclusion:The intelligent gastrointestinal endoscopy quality control system with a review and feedback could monitor and improve the quality of gastroscopy.
