Endoscopic Quality Improvement System Study

Study Overview
=================
Brief Summary
-----------------
We intend to develop intelligent quality control and management software based on the work of digestive endoscopic artificial intelligence in the Department of Gastroenterology, Wuhan University Renmin Hospital, to accurately and comprehensively assess the quality of gastrointestinal endoscopy and to provide a practical basis for improving the quality of digestive endoscopy in our endoscopic center.

Official Title
-----------------
A Prospective, Single-center Study Evaluating the Effectiveness of Endo.Adm in Improving the Quality of Gastrointestinal Endoscopy

Conditions
-----------------
Adenoma Colon, Gastric Precancerous Condition

Intervention / Treatment
-----------------
* Behavioral: Quality audit and feedback
* Behavioral: Control


Participation Criteria

Masking: Single


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Sham Comparator: Control group<br>Endoscopists in control group were informed standard quality indicators requirements and the corresponding references during informed consent. | Behavioral: Control<br>* None feedback.<br>|
| Experimental: Feedback group<br>Endoscopists in feedback group were informed standard quality indicators requirements and the corresponding references during informed consent. In addition to the quality requirements, endoscopists randomized to feedback group received customized quality reports feedback from Endo.Adm weekly. | Behavioral: Quality audit and feedback<br>* Endoscopists received quality report generated by Endo.Adm.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Adenoma detection rate | ADR was calculated by dividing the total number of patients being detected adenomas by the number of colonoscopies. | 3 Months | 
| Gastric precancerous detection rate | GPCs detection rate was calculated by dividing the total number of patients being detected gastric precancerous by the number of gastroscopies. | 3 Months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Adcanced ADR | Adcanced ADR was calculated by dividing the total number of patients being detected ≥10mm in size, or adenomas with histopathology of tubulovillous, villous, adenocarcinoma, or high-grade dysplasia by the number of colonoscopies. | 3 months |
