INTRODUCTION Positive correlation between examination time and neoplasm detection using esophagogastroduodenoscopy (EGD) has been described by observational studies, but the effect of setting minimal examination time still requires investigation. METHODS This prospective, 2-stage, interventional study was conducted in 7 tertiary hospitals in China, enrolling consecutive patients undergoing intravenously sedated diagnostic EGDs. In stage I, the baseline examination time was collected without informing the endoscopists. In stage II, the minimal examination time was set for the same endoscopist according to the median examination time of normal EGDs in stage I. The primary outcome was the focal lesion detection rate (FDR), defined as the proportion of subjects with at least one focal lesion among all subjects. RESULTS A total of 847 and 1,079 EGDs performed by 21 endoscopists were included in stages I and II, respectively. In stage II, the minimal examination time was set as 6 minutes, and the median time for normal EGD increased from 5.8 to 6.3 minutes ( P < 0.001). Between the 2 stages, the FDR was significantly improved (33.6% vs 39.3%, P = 0.011), and the effect of the intervention was significant (odds ratio, 1.25; 95% confidence interval, 1.03-1.52; P = 0.022) even after adjusting for subjects' age, smoking status, endoscopists' baseline examination time, and working experience. The detection rate of high-risk lesions (neoplastic lesions and advanced atrophic gastritis) was also significantly higher in stage II (3.3% vs 5.4%, P = 0.029). In the endoscopist-level analysis, all practitioners reached a median examination time of 6 minutes, and the coefficients of variation of FDR (36.9%-26.2%) and examination time (19.6%-6.9%) decreased in stage II. DISCUSSION Setting a 6-minute minimal examination time significantly improved the detection of focal lesions during EGDs and has the potential to be implemented for quality improvement.
