Objective:Bayley-III scales are currently used to evaluate outcomes of term infants following hypothermia therapy, while all before reported outcomes in this population have used Bayley-II. Our objectives were to determine the incidence of abnormal neurodevelopmental outcomes using Bayley III and the predictive value of Magnetic resonance imaging (MRI) in infants who received systemic hypothermia.Study Design:We conducted a prospective cohort study of inborn infants who underwent hypothermia for moderate/severe neonatal encephalopathy from October 2005-November 2011.Result:Eighty newborns underwent hypothermia (incidence of 1/1000). Of the survivors, 89% had Bayley-III performed around 24 months of age. An abnormal outcome using Bayley-III <85 occurred in 50%, while Bayley III <70 occurred in 13%. MRI predicted Bayley III<85 with sensitivity of 73%, specificity of 84%, positive-predictive value of 84% and negative-predictive value of 74%.Conclusion:A Bayley-III 85 cutoff identifies a disability rate of 50%, and MRI was predictive of abnormal outcomes. Findings can be useful for counseling of families and planning of future studies using Bayley III.
