Added Value of Late Auditory Evoked Potentials in the Multimodal Prognostication of Patients With Disorders of Consciousness

Crit Care MedPublished Retrospective cohort study

Authors' conclusion

Integrating late AEPs into multimodal assessments enhances the model's predictive performance.

Study context

Population
Patients with disorders of consciousness at the subacute phase after coma onset (median, 20.0 d), single institutionHypoxic-ischemic brain injury (HIBI) in 43.9%
Participants
148 patients
Exposure
Model including late auditory evoked potentials (AEPs) (MMN, P3) vs model with well-established markers only, stratified HIBI vs non-HIBI
Outcome
Unfavorable outcome (Glasgow Outcome Scale-Extended 1-2)
Follow-up
3 months

PPV of EEG malignant patterns and absent reactivity for unfavorable outcome

Predictive values of neurophysiologic markers generally lower in non-HIBI than HIBI
