Computerized Adverse Event Surveillance System

Abstract

Background: Although, in Korea, adverse event would be a serious healthcare problem like many western countries, patient safety is not a major concern among medical informaticist, clinicians, and policy makers. We need to understand the utility of the computerized adverse events surveillance system(AESS) which is the most cost-effective method to detect and prevent patient injury. Objective: To review methodologies of detecting adverse events using information technology, adverse drug event surveillance system, critical laboratory alerting system, and adverse medical device event surveillance system. Methods: Recent studies on adverse event surveillance using information technology were reviewed. Results: For each system, the author reviewed essential concepts, signals and rules, software system architectures, review processes, and effect of system implementations related to AESS. Conclusion: If the utility of AESS is proved and professional consensus is formulated among medical informaticist, computerized detection of adverse events could be practical on a widespread basis in Korea.
