Recognising signs of deteriorating health in patients and responding to them appropriately are crucial nursing competencies. In acute care, failure to detect and act promptly on deterioration can lead to the patient’s death. To achieve clinical competence, nursing students require training in the use of techniques for monitoring physiological observations as well as protocols that enable them to respond to deterioration. The use of early warning scores has been advocated to standardise the methods and frequency of patient monitoring in acute care settings. In 2012, the Royal College of Physicians developed the National Early Warning Score (NEWS), which was updated in 2017 and known as NEWS2. This early warning score is used in acute hospitals in England, Scotland, Wales and Northern Ireland. This article explores the benefits and challenges of using NEWS2 as an educational tool in pre-registration nursing programmes to support nursing students in recognising and responding to deteriorating health.
