For families whose newborn requires neonatal intensive care, the NICU can become an entire world they never expected to enter. Days may be measured in grams gained, oxygen levels, feeding milestones, medications, procedures, and small signs of progress that carry enormous meaning. A number on a monitor, a few more milliliters at feeding, or another day of development can change the course of a baby’s care.
For the clinicians caring for these infants, those details matter just as much. Each one helps tell the story of an individual baby. But when information from thousands of babies is collected and studied over time, those individual experiences become part of something much larger. They help researchers understand risk, evaluate treatments, track outcomes, and continue to improve what is possible for babies born too soon or who are critically ill.
Today, approximately one in 10 babies in the United States is born preterm. Behind that statistic are hundreds of thousands of individual babies and families each year, each with their own course of care and outcome.
During NICU Awareness Month, we recognize the babies, families, and healthcare professionals whose lives intersect in the NICU. It is also an opportunity to examine how much neonatal care has changed and how information gathered from babies who came before continues to shape care before birth, in the NICU, and long after a child goes home.
What Can We Learn From NICU Data?
The clinical picture of a premature or critically ill newborn is extraordinarily detailed. Gestational age and birth weight are important, but they are only part of the story. Depending on the patient and the questions being studied, neonatal data may include maternal and pregnancy factors, antenatal treatments, delivery information, Apgar scores, resuscitation, respiratory support, nutrition, infections, medications, surgical procedures, complications, length of stay, and post-discharge outcomes.
Looking at these details together helps researchers understand how different factors may influence an infant’s outcome. A 2025 study of extremely premature infants examined infants born between 22 and 26 weeks of gestation and evaluated factors including gestational age, birth weight, antenatal corticosteroid administration, Apgar scores, respiratory interventions, nutrition, and neonatal complications.
Researchers found that higher gestational age and birth weight were strongly associated with survival. Antenatal corticosteroid administration and enteral feeding were also associated with improved outcomes. Respiratory distress syndrome was the most common morbidity among the infants studied, while late-onset sepsis affected more than a third.
The study focused on a single patient population at a single center, but it illustrates the level of detail required to understand neonatal outcomes. A baby’s gestational age tells us something. Birth weight tells us something else. Treatment, nutrition, infection, respiratory needs, and complications add additional pieces to the picture. Across larger populations and over time, those details help build the evidence neonatal teams use to understand risk and improve care.
The Impact of Data Can Begin Before the NICU
Not every advance in neonatal care happens after a baby is born. Years of research into preterm birth have improved our understanding of which pregnancies may be at increased risk and what can be done when an early delivery appears likely. In some cases, identifying that risk gives clinicians an opportunity to act before a baby ever reaches the NICU.
Antenatal corticosteroids can be administered when preterm delivery is anticipated to accelerate fetal maturation and reduce complications associated with prematurity. Magnesium sulfate administered before anticipated early preterm birth can reduce the risk of cerebral palsy, and other interventions may provide additional time for treatments to take effect or for a mother to be transferred to a facility equipped to provide the appropriate level of neonatal care. That ability to prepare represents an important shift. A premature delivery that might once have come with little warning can sometimes be anticipated, giving both the obstetric and neonatal teams valuable time to intervene and prepare.
Today’s recommendations are built on years of research on pregnancies, interventions, births, and infant outcomes. Each patient adds to a growing body of knowledge that can influence the care provided to future mothers and babies. The impact of neonatal data can begin before a newborn ever enters the NICU, ensuring the best possible outcomes for the infant and their family.
NICU Data Helps Us See How Far Care Has Come
The impact of data for infants becomes even more striking when we look at survival. A large study highlighted by Stanford Medicine examined 10,877 infants born between 22 and 28 weeks of gestation at 19 U.S. academic medical centers from 2013 through 2018. Overall survival reached 78%, compared with 76% among infants studied from 2008 through 2012. On paper, two percentage points may not look dramatic. Across the population of extremely premature infants, however, researchers noted that the improvement translates into hundreds of additional babies surviving each year.
Outcomes at the earliest gestational ages show just how much neonatal medicine has changed. Among babies born at 22 weeks who received active treatment, approximately 28% survived. At 23 weeks, survival reached 55%.
Stanford’s researchers put those numbers into historical context. In the mid-1980s, an infant born at 25 weeks and weighing approximately 500 grams generally was not expected to survive. Today, the edge of viability has moved toward 22 weeks. That change represents decades of advances in respiratory support, nutrition, medications, infection prevention, prenatal interventions, technology, and clinical practice.
Data did not create those advances on its own. But without collecting and studying outcomes across large groups of infants and over long periods of time, it would be far more difficult to understand which approaches are associated with better outcomes, where progress is occurring, and which challenges remain. And behind every improvement in a survival rate is something a percentage cannot fully capture: another baby who went home with their family.
The Value Extends Beyond the NICU Stay
Going home is an enormous milestone, but it is not the end of the story. As survival among extremely premature infants has improved, researchers have increasingly focused on what happens after discharge. Long-term data helps provide a more complete understanding of development, disability, ongoing medical needs, and quality of life.
The research highlighted by Stanford followed children born between 22 and 26 weeks and evaluated their outcomes at age 2. Approximately half had mild or no neurodevelopmental impairment. Twenty-nine percent experienced moderate disability, and 21% had severe impairment. About half had also been rehospitalized after leaving the NICU.
Researchers examined outcomes including cerebral palsy, hearing and vision impairment, mobility, feeding challenges, and the need for ongoing equipment and medications.
These findings are an important reminder that survival is only one measure of progress. Following children beyond their initial hospitalization allows researchers to ask deeper questions. How are children developing? Which early interventions are associated with better long-term outcomes? What healthcare needs continue after discharge? Where can neonatal and pediatric care improve next?
The answers may take years to emerge, which makes longitudinal pediatric data particularly valuable. The information gathered during and after a child’s NICU experience can continue to contribute to our understanding of neonatal care long after the child leaves the hospital.
Turning Pediatric Registry Data Into a Resource for Better Care
The progress made in neonatal care did not come from a single discovery. It reflects decades of clinical expertise, medical innovation, research, technology, quality improvement, and a continually expanding understanding of the factors that influence outcomes for premature and critically ill newborns. Data runs through that entire continuum.
