Objective The Apgar score has been shown to have utility in predicting mortality in the extremely preterm infant in delivery hospital populations, where most mortality occurs within 12 hours of birth. We tested the hypothesis that the 5 minute Apgar score would remain associated with mortality in extremely preterm infants after transfer from the delivery hospital to an all referral neonatal intensive care unit at an average age of 10 days.
Study Design A retrospective analysis of 454 infants born at < 27 weeks gestation.
Results The median Apgar score was 3 at 1 minute (interquartile range [IQR] 2-6) and 6 at 5 minutes (IQR 4-7). The Apgar score increased from 1 to 5 minutes by 2.0 +/- 1.7 (p < 0.001). In logistic regression modeling, an Apgar score of < 5 at 5 minutes was associated with an increased mortality (odds ratio 1.76 [95% confidence interval 1.06-2.94], p < 0.05), but not morbidities.
Conclusion Infants born at < 27 weeks gestation admitted to an all referral children's hospital at a mean age of 10 days with a 5 minute Apgar < 5 are at an increased risk of mortality. Our findings continue to support the importance of the Apgar score given at delivery even in the extremely preterm infant referred to a nondelivery children's hospital.
