About the Data

To develop this tool, researchers used data from standardized assessments of nearly 5,000 preterm infants born at hospitals within the NICHD Neonatal Research Network (NRN) between 2006 and 2012.

NRN researchers then confirmed their findings using data from 51,000 infants born between 2006 and 2012, and 26,000 infants born between 2013 and 2016, at hospitals participating in the Vermont Oxford Network (VON) . VON is a nonprofit organization dedicated to improving the quality, safety, and value of care for newborn infants and their families through quality improvement, education, and research.

NRN researchers also used VON data to describe differences in survival across U.S. hospitals. Hospitals submit data to VON about infant care practices and outcomes, including for more than 85 percent of the extremely preterm infants born in the United States.
