Cost-effectiveness of Therapeutic Hypothermia in Neonates with Mild Hypoxic Ischemic Encephalopathy

Neonatal hypoxic ischemic encephalopathy (HIE) has an incidence of 1.5 per 1000 livebirths and results in significant sequelae, including death, cerebral palsy, epilepsy, and intellectual disability. Therapeutic hypothermia is now standard of care for moderate to severe HIE as it has been shown to reduce death or disability in survivors. However, hypothermia is commonly being utilized in mild cases of HIE despite a lack of evidence of clinical efficacy. We aim to characterize the long-term neurodevelopmental outcomes of infants with mild HIE who undergo hypothermia versus those who do not while quantifying the economic burden of mild HIE over a lifetime. We will use this data to build an economic model and compare the incremental cost per quality-adjusted life year between those who undergo therapeutic hypothermia versus standard care. Findings of this analysis will aid stakeholders in understanding the economic implications and incremental benefits, if any, of inducing hypothermia in neonates with mild HIE.
