    When to Use
    Pearls/Pitfalls
    Why Use

    Pediatric inpatients.

    • Originally developed to provide a practical and objective method to identify pediatric inpatients at risk for cardiac arrest.
    • Can be used by staff and providers at all levels to escalate care for sick patients.

    Provides an objective measurement for patients who “look sick.”

    Advice

    Consider escalation of care in patients with high (≥3) PEWS, including escalating to senior staff, increasing frequency of vital signs measurements and clinical assessments, and/or consultation to an intensive care unit.

    Formula

    Addition of assigned points.

    Facts & Figures

    Score interpretation:

    • PEWS ≤2: low risk
      • Reassess as needed
    • PEWS 3-4: intermediate risk
      • Recommended to alert charge nurse and staff MD
    • PEWS ≥5: high risk
      • Recommended to initiate rapid response team

    Evidence Appraisal

    The Pediatric Early Warning Score (PEWS) was developed by expert consensus by a multidisciplinary group at Brighton and Sussex University Hospitals NHS Trust in the UK in order for nurses and junior medical staff to identify pediatric patients at risk for clinical deterioration.

    Triggers were identified by polling a multidisciplinary group at all levels of patient care on what clinical features they considered concerning, including both appearance and vital signs. The criteria were revised based on a pilot that identified patients who deteriorated who were not identified by the original score.

    Several studies have validated the PEWS, including one by Duncan et al which found an area under the receiver operating characteristic curve of 0.90, with 78% sensitivity and 95% specificity at a score of 5.
