Background:
Despite the introduction of therapeutic hypothermia, infants with moderate-to-severe hypoxic-ischemic encephalopathy remain at risk of mortality and morbidity. A dedicated service with standardized management protocols and improved communication may help improve care. We aimed to evaluate the impact of a dedicated neonatal neurocritical care service on short-term outcomes in infants with hypoxic-ischemic encephalopathy.
Methods:
We performed a retrospective cohort study (July 2008 to December 2017) on term and near-term infants admitted to two tertiary neonatal intensive care units with moderate-to-severe hypoxic-ischemic encephalopathy, before and after neonatal neurocritical care service implementation. The primary outcome was brain magnetic resonance imaging findings consistent with those of hypoxic-ischemic encephalopathy. Secondary outcomes included the cooling initiation rate, hospital stay duration, antiseizure medication use, and inotrope use. Regression analysis and interrupted time series analysis were performed after adjusting for confounding factors.
Results:
In total, 216 infants with moderate-to-severe hypoxic-ischemic encephalopathy were analyzed-109 before and 107 after neonatal neurocritical care implementation. After adjusting for confounding factors, there was a significant reduction in primary outcomes (adjusted odds ratio: 0.3, confidence interval: 0.15 to 0.57, P < 0.001) after neonatal neurocritical care implementation. Average hospital stay duration reduced by 5.2 days per infant (P = 0.03), identification of eligible infants for cooling improved (P < 0.001), antiseizure medication use reduced (P = 0.001), and early inotropes use reduced (P = 0.04).
Conclusion:
Implementation of a neonatal neurocritical care service associated with decreased brain injury shortened the hospital stay duration and improved the care of infants with moderate-to-severe hypoxic-ischemic encephalopathy.
