This retrospective, multicenter, observational study evaluates how well a decision-support algorithm can tell apart mild forms of hypoxic-ischemic encephalopathy (HIE) from moderate or severe forms in full-term newborns born after a lack of oxygen around birth (perinatal asphyxia). The algorithm reads the raw (non-compressed) EEG signal. Its output is compared with the reference reading of the full conventional EEG made by a panel of pediatric neurophysiologists together with the baby's clinical information. The study uses only medical data that already exists and asks nothing of the babies or their families.
The algorithm under investigation was developed in a previous retrospective clinical study (registered as NCT05114070; French CNIL/ethics ref CER-2021-023; approved by the Sorbonne University ethics committee) and is based on background-rhythm analysis of EEG. Newborns are analyzed in two subgroups: those who received a treatment liable to modify the EEG tracing, and those who did not. Conventional EEG recordings are collected from the neurophysiology departments of participating level-3 maternity hospitals over the period 01 January 2016 to 30 April 2026. No follow-up or sampling is performed.
| Arm | Type | Interventions | Description |
|---|---|---|---|
| Term newborns with suspected HIE | Single study population: term newborns (≥ 36 weeks, ≥ 1800 g) with suspected hypoxic-ischemic encephalopathy in a context of perinatal asphyxia, with an available non-compressed conventional EEG. This is a diagnostic-accuracy validation study (STARD), not a comparative two-arm design. The treated / untreated distinction is a pre-specified analysis subgroup only, not a study group. |
