Agreement Between Telemedicine and In-Person Examination for Neonatal Hypothermia Decisions

Therapeutic hypothermia within 6 hours of birth is critical for newborns with hypoxic-ischemic encephalopathy (HIE) but is often delayed by transfers to appropriate facilities. Telemedicine (TM) based hypothermia evaluation could expedite these assessments. There is limited evidence on the efficacy of TM compared with the in-person (IP) Sarnat examination. In this study, we aim to compare the TM with the IP examination in infants with suspected HIE.

Newborns were enrolled from March 2022 to December 2023. All infants underwent IP and TM assessments using the modified Sarnat examination within 6 hours after birth. Data included neurologic examination scores for both IP and TM, decisions for hypothermia qualification, and TM technology metrics. Cohen's kappa statistic (κ) was used to measure the interrater agreement between IP and TM examination findings.

170 Sarnat assessments (IP and TM) were performed on 85 enrolled infants. The results show almost perfect agreement between IP and TM regarding signs of moderate or severe HIE (κ = 0.82) and the decision for hypothermia intervention (κ = 0.82). We report fair to moderate agreement (κ = 0.33-0.58) for individual categories of the neurologic examination. 93% of TM examinations were completed within 15 minutes, and 79% of the TM encounters had no technology issues.

This study compares IP and TM assessments in infants requiring hypothermia evaluation. Findings show that TM is feasible and not significantly different from IP for making hypothermia decisions in suspected HIE. This could enhance remote Sarnat evaluations and initiate earlier therapeutic interventions.
