Early Warning Systems: Introduction and Application

Abstract

Related studies in the literature indicate that over half (50-84%) of patients exhibit physiological variations 6 hours before experiencing cardiac arrest. Early warning systems improve the ability of medical teams to detect patient deterioration and then immediately treat sudden cardiac arrest during patient hospitalization. This article aims to strengthen general understanding among clinical medical staffs of the early warning system. Understanding the reasons and motivations for establishing this system is expected to help readers better distinguish the physiological monitoring indicators of this system and its importance in terms of improving patient safety. In particular, using the system to identify patients at risk levels of medium or higher will help facilitate their timely transfer to an intensive care unit for appropriate monitoring and care. This article further explores the application of early warning systems in nursing to help nurses understand their professional roles and responsibilities as members of the rapid-response team. Finally, information in this article teaches medical staffs how to avoid unanticipated cardiac arrest events, create a comprehensive patient safety environment, and improve the quality of medical care.
