Supplementary Material for: “Mild’’ Hypoxic-Ischaemic Encephalopathy and Therapeutic Hypothermia: A Survey of Clinical Practice and Opinion from 35 Countries
Introduction: We aimed to determine global professional opinion and practice for the use of therapeutic hypothermia (TH) for treating infants with mild hypoxic-ischaemic encephalopathy (HIE). Methods: A web-based survey (REDCap) was distributed via emails, social networking sites, and professional groups from October 2020 to February 2021 to neonatal clinicians in 35 countries. Results: A total of 484 responses were obtained from 35 countries and categorized into low/middle-income (43%, LMIC) or high-income (57%, HIC) countries. Of the 484 respondents, 53% would provide TH in mild HIE on case-to-case basis and only 25% would never cool. Clinicians from LMIC were more likely to routinely offer TH in mild HIE (25% v HIC 16%, p v HIC 26%, p v HIC 32%, p v HIC 40%, p v HIC 95%, p Conclusions: This is the first survey of global opinion for TH in mild HIE. The overwhelming majority of professionals would consider “cooling” an infant with mild HIE, but LMIC respondents were more likely to routinely cool infants with mild HIE and use adjunctive tools for diagnosis and follow-up. There is wide practice heterogeneity and a sufficiently large RCT designed to examine neurodevelopmental outcomes, is urgently needed and widely supported
