The PEWS score is an early warning of a child’s condition and can be used as an effective scoring tool to predict the risk of a child’s condition in children under the age of 18 years, thereby reducing the rate of child mortality. The PEWS score is based on the Early Warning Score for Adults (EWS) and is used for pediatric patients in general wards. Typically, physicians assess the respiratory, circulatory, and psychobehavioral aspects of a child’s condition to determine whether cardiopulmonary failure is present and whether transfer to an intensive care unit (ICU) or to a higher level of care is warranted. Respiratory, circulatory, and psychobehavioral aspects are given different scores according to their warning levels, and the PEWS is the sum of the scores, with the higher the score, the more serious the child’s condition.
