Abstract: Objective：To evaluate the effectiveness of the computer-based auto-verification system in the adverse event reports of intrauterine device (IUD), so as to provide suggestion and improve this system. Methods: 5% samples from 6 520 adverse event reports of intrauterine device collected by SCARS from January to May of 2017 were selected and scored. Results: In this assessment, the reports auto-verificated by computer were 45.83% of the total reports. 339 cases including various types of adverse events were collected and evaluated, with an average score of (97.01±4.20). Most of the reports lost scores in the part of adverse event evaluation. Conclusions: It is necessary to develop a computer-based auto-verification system for the increasing number of intrauterine device adverse event reports. It could be widely applied with improved and perfect function.
