Abstract: With the deep application of information technology in the medical field, the number of information technology-related medical adverse events has been increasing. In this paper, the terms, concepts, and research status of medical adverse events related to information technology were reviewed and classified from three aspects:manifestation, system composition, and error causes. And the corresponding definitions and case descriptions were discussed. Based on relevant research in China and abroad, this paper further explored the counter measures for information technology-related medical adverse events, and proposes solutions to enhance attention, encourage reporting, and establish a standardized prevention system. Hopefully, this review will get more attention of medical industry to information technology-related medical adverse events and provide knowledge and reference for relevant research.
