Abstract Aim Associations between serum biomarkers S100 calcium‐binding protein B (S100B) and neuron‐specific enolase (NSE) in neonates with hypoxic‐ischaemic encephalopathy (HIE) offer contradicting data in regard to neurocognitive outcome. The aim of our study was to provide another dataset to answer this question if S100B or NSE correlates to outcome in neonatal HIE. In addition, we investigate whether amplitude‐integrated EEG (aEEG) or magnetic resonance imaging (MRI) also has predictive value. Methods In neonates with HIE born in Vorarlberg, Austria, ( n = 34) from 2012to 2020, NSE and S100B serum levels were measured on day one. aEEG was installed at admission and MRI performed within 7 days. Surviving children ( n = 27) were categorised as good or poor outcome by using an age‐appropriate neurocognitive test and a standardised neurological follow‐up. Positive and negative predictive values and receiver operating characteristic curves were calculated to evaluate the prognostic value. Results S100B showed best positive and negative predictive value, 72.7% and 90.5%, respectively, and a significant area under the curve of 0.820. NSE showed a positive and a negative predictive value of 43.8% and 81.3% and an area under the curve of 0.757. Severely abnormal aEEG and abnormal MRI significantly correlated with outcome ( p = 0.024 and 0.001 respectively). Conclusion S100B and NSE on day one, severely abnormal aEEG and abnormal MRI show a significant correlation and good predictive value for neurocognitive outcome.
