Phase was not associated with GCS at either time point. Associations between gain and GCS 24 hours later remained significant in generalized estimating equations (low frequency β=−0.83, p=0.001; high frequency β=−1.10, p<0.001) after accounting for SOFA and GCS at the time of DCA evaluation.Conclusions: Impaired cerebral autoregulation may be a predictive biomarker of worsening HE severity. Further studies are needed to confirm our findings.Study Supported by: Research was supported by the National Institutes of Health’s National Center for Advancing Translational Sciences, Grant Number KL2TR001424, and the National Institutes of Health, Grant Number L30 NS098427.Disclosure: Dr. Liotta has nothing to disclose.
