No new drug approvals or safety communications affecting paediatrics today. The standards development that matters is a consensus definition of neonatal encephalopathy, reached by international real-time Delphi.
The problem it addresses is real and long-standing: neonatal encephalopathy, hypoxic-ischaemic encephalopathy and perinatal asphyxia have been used interchangeably across clinical trials and communication, which conflates a syndrome with one of its causes. That makes evidence synthesis harder than the underlying biology warrants, and makes conversations with parents less precise than they should be.
The process drew 235 complete and 143 partial responses from 52 countries, 20% from low- and middle-income settings, with 6% representing parents and caregivers, followed by three consensus meetings. The agreed primary domain defines neonatal encephalopathy as a heterogeneous clinical condition of abnormal or impaired brain function with multiple potential causes, presenting with altered consciousness and possibly seizures, abnormal reflexes, altered tone, posture or movement, or an abnormal brain-related breathing pattern.
The useful discipline is the separation: encephalopathy is what you observe, hypoxic-ischaemic is a claim about why. Recording the first without asserting the second is more accurate and, in a condition with medicolegal weight, more defensible.
- No new approvals or safety communications for paediatrics today
- Neonatal encephalopathy is the syndrome; hypoxic-ischaemic is one aetiology
- Definition organised into primary, secondary and tertiary domains
- Parents and caregivers were included in the consensus, which is uncommon
- Adopt the terminology in notes and discharge summaries before trials adopt it
The statistics, in plain English
A Delphi process produces agreement, not evidence — its validity rests on who was asked and whether disagreement was surfaced rather than averaged away. Two features strengthen this one: participation from 52 countries with a fifth from low- and middle-income settings, and the inclusion of families, whose stake in the terminology is direct.
