【subjects and methods】 We included 155,312 endoscopic examinees from fiscal 2008 to fiscal 2019 (before the introduction of the new system) and 23,802 endoscopic examinees in 2020 and 2021 fiscal years (after the introduction of the new system; 14,056 examinees used the new system). We identified several disadvantages of the examinees using the conventional examinations: 1)loss of examinees’ data, 2)incorrect entries in the examination sheets, reading errors of OCR sheets, and manual input errors, 3)mistakes in notifying the examinees of the examination results, and 4)difficulty in backing up a large number of images. We examined whether the new system reduced these disadvantages. We also evaluated the office burden of the medical association staff.
