Therapeutic hypothermia (TH) improves the outcome in newborns with hypoxic-ischemic encephalopathy (HIE) and should be used in case of perinatal asphyxia and signs of moderate/severe HIE. Frequency of HIE and the application of TH were extracted from the neonatal survey, a registry that collects data from all German hospitals, and from the hypothermia registry, established in 2010. The latter was also used to analyze short-term outcomes of the newborns. Between 2010 and 2017, 106 of Germany's 213 perinatal centers joined the registry. Response rates varied between 22 and 60%. The registry recorded 164 (IQR 115-224) TH cases per year in newborns with HIE. In the neonatal survey, 517 (382-664) TH and 543 (432-581) HIE cases were reported. Since 2014 there have been more cases of TH than HIE. After TH, 10.4% (8-13%) of the newborns died, 81% (78-82%) of the newborns were discharged home, 3.6% (3-5%) to a rehabilitation facility, and 5.4% (5-7%) transferred to another clinic. 89% (87-89%) were on complete oral feedings. After the introduction of TH in the clinical routine, the number of treated newborns increased continuously. Currently, the number of TH is higher than the number of children with HIE, which is difficult to explain, as the presence of a moderate or severe HIE is a mandatory requirement for TH. The data from the hypothermia registry showed no significant changes in mortality or neurological outcome over time.
