Early warning scores: unravelling detection and escalation

Abstract

Purpose – The purpose of this paper is to increase understanding of how patient deterioration is detected and how clinical care escalates when early warning score (EWS) systems are used. Design/methodology/approach – The authors critically review a recent National Early Warning Score paper published in IJHCQA using personal experience and EWS-related publications, and debate the difference between detection and escalation. Findings – Incorrect EWS choice or poorly understood EWS escalation may result in unnecessary workloads forward and responding staff. Practical implications – EWS system implementers may need to revisit their guidance materials; medical and nurse educators may need to expand the curriculum to improve EWS system understanding and use. Originality/value – The paper raises the EWS debate and alerts EWS users that scrutiny is required.
