Abstract

Background

Ethnic and racial disparities in neonatal outcomes have been well-documented, including higher risk of hypoxic-ischemic encephalopathy (HIE). Therapeutic hypothermia (TH) is the only approved treatment for infants with moderate to severe HIE and previous studies have shown mixed results regarding the impact of timing of initiation of TH on outcomes. These studies often include both inborn and outborn neonates and few minority patients.

Study design

This retrospective cohort study of exclusively inborn neonates from a high-volume, urban, safety net hospital (SNH) serving primarily racial/ethnic minority patients assessed the impact of timing of initiation of TH on short-term outcomes.

Results

There were 268 infants diagnosed with moderate or severe HIE from 2009 to 2023. After excluding patients for late cooling (n = 32), participation in a clinical trial (n = 41), and major comorbidities (n = 8), there were 187 patients for analysis. Similar to our neonatal population, this study cohort consisted of 94 % racial/ethnic minority patients. The average time to initiate TH was 4.4 ± 1.1 h of life (HOL) and 88 % of qualifying neonates received TH by 6 HOL. Those initiating TH at <4 HOL compared to 4–6 HOL were more likely to have severe HIE (p = 0.01). The adjusted OR for the primary outcome of in-hospital death was not associated with timing of initiation of TH [aOR = 0.75 (95 % CI 0.40–1.33); p = 0.33], nor were secondary outcomes of abnormal brain MRI or length of stay.

Conclusion

In a vulnerable population from a high-volume SNH, timing of initiation of TH was not associated with short-term outcomes.

期刊介绍： Established as an authoritative, highly cited voice on early human development, Early Human Development provides a unique opportunity for researchers and clinicians to bridge the communication gap between disciplines. Creating a forum for the productive exchange of ideas concerning early human growth and development, the journal publishes original research and clinical papers with particular emphasis on the continuum between fetal life and the perinatal period; aspects of postnatal growth influenced by early events; and the safeguarding of the quality of human survival. The first comprehensive and interdisciplinary journal in this area of growing importance, Early Human Development offers pertinent contributions to the following subject areas: Fetology; perinatology; pediatrics; growth and development; obstetrics; reproduction and fertility; epidemiology; behavioural sciences; nutrition and metabolism; teratology; neurology; brain biology; developmental psychology and screening.
