For Immediate Release: Tuesday, January 18, 2022 CONTACT: Linda Huynh or Robert Bock, 301-496-5133, <e-mail:nichdpress@xxxxxxxxxxxx> SURVIVAL RATE INCREASES FOR EXTREMELY PRETERM INFANTS IN NIH-FUNDED RESEARCH NETWORK WHAT: The survival rate of extremely preterm infants born from 2013 through 2018 in a large network of U.S. research centers improved to 78.3%, compared to 76% for infants born in the network from 2008 to 2012, according to researchers funded
by the National Institutes of Health. Their study included more than 10,000 infants born at 22 to 28 weeks of pregnancy at 19 centers of the Neonatal Research Network funded by NIH’s Eunice Kennedy Shriver National Institute of Child Health and Human Development
(NICHD). It was led by Edward F. Bell, M.D., of the University of Iowa, Iowa City, and appears in the Journal of the American Medical Association.
In the study, survival was greater for infants born later in pregnancy, with 94% of those born at 28 weeks surviving to hospital discharge and roughly 11% born at 22 weeks surviving to discharge. Survivors were assessed at 2 years corrected
age -- a child’s chronological age, minus the number of weeks the child was born preterm. Slightly more than 8% had moderate to severe cerebral palsy, 1.5% had vision loss in both eyes, 2.5% needed hearing aids or cochlear implants, and 15% required mobility
aids such as braces, walkers, or wheelchairs. Nearly 49% had no or only mild neurodevelopmental impairment, about 29% had moderate neurodevelopmental impairment and roughly 21% had severe neurodevelopmental impairment. The causes <https://www.nichd.nih.gov/health/topics/preterm/conditioninfo/causes>of preterm birth are only partially understood. The researchers noted that the infants were treated at academic medical centers and their health outcomes may
not reflect those of the whole U.S. preterm population. Additional funding for the study was provided by NIH’s National Center for Advancing Translational Sciences.
