Early Warning Score

The Early Warning Score (EWS), most commonly known as the National Early Warning Score (NEWS) in the UK, is a standardized tool for identifying acutely unwell patients at risk of deterioration. Developed by the Royal College of Physicians and validated through research by Smith, Prytherch, and colleagues, NEWS combines vital sign measurements and supplemental oxygen use to generate a composite score. High NEWS scores trigger escalated care responses, enabling early intervention before critical illness develops.
