Paediatric sepsis: the outcome is often set before the ICU

A review takes stock of how paediatric sepsis has changed. The Phoenix Sepsis Criteria have moved the definition away from inflammation (the old systemic inflammatory response) towards life-threatening organ dysfunction, and conjugate vaccine programmes have changed which children present with invasive bacterial infection. Guidance increasingly stratifies treatment by severity rather than applying one bundle to all.

The sobering point is where deaths happen: many occur within the first 24 hours of referral to intensive care, meaning outcomes are frequently decided before a child reaches the unit. Early recognition remains the weak link, screening tools perform imperfectly in unselected febrile children, biomarkers are only adjuncts, and clinicians still depend on gestalt and parental concern.

For practice, this keeps the emphasis on front-door recognition and timely escalation rather than on any single score. Machine-learning and phenotype-based tools may help, but need prospective validation before routine use.

• The Phoenix criteria define sepsis by organ dysfunction, not inflammatory markers.
• Many paediatric sepsis deaths occur within 24 hours of intensive-care referral.
• Screening tools underperform in unselected febrile children; biomarkers are adjuncts.
• Parental concern and clinical gestalt remain central to early recognition.
• Treat recognition and timely escalation at the front door as the priority.

Why it matters

If most deaths are set before the ICU, improving front-door recognition matters more than any single in-unit intervention.

Don't overread it

This is a narrative review; the newer machine-learning and phenotype tools it describes are not yet validated for routine use.
