World’s largest early warning system for severe child illness to launch in NHS A&Es across England

The National Health Service in England is rolling out a standardised paediatric early warning system across accident and emergency departments, marking the first time the system will be used in this setting. The initiative represents the world’s largest deployment of such a standardised scoring approach for assessing children’s vital signs in emergency care.

The system, known as Pews, uses vital sign measurements including blood pressure, heart rate, breathing rates, oxygen levels and consciousness assessments to generate scores that alert medical staff when a child’s condition is worsening. The scoring framework includes age-appropriate charts designed to identify abnormal signs of deterioration in babies, children and young people. NHS England officials emphasised that the system is tailored specifically for the rapid decision-making required in busy emergency departments.

According to NHS England, more than 6 million children visit A&E departments across England annually. The rollout follows successful use of Pews in hospital inpatient settings, where data indicates consistently lower rates of cardiac arrests among patients in more than 90 hospitals currently using the system. A comparable early warning system for adults has been in use across NHS hospitals for some time.

Healthcare leaders stressed that while the scoring system provides important guidance, it is designed to complement rather than replace clinical judgment and input from parents, carers and children themselves. Concerns raised by these parties can trigger immediate escalation of care even if a child’s Pews score indicates lower risk. Duncan Burton, England’s chief nursing officer, highlighted the system’s role in helping staff recognise deterioration signs and communicate concerns during time-sensitive situations.

Along with the Pews rollout, NHS England is developing new standards for paediatric A&E care, with eliminating corridor care for children identified as a priority. Professional bodies including the Royal College of Paediatrics and Child Health and the Royal College of Nursing supported development of the emergency department version of the system.
