Characterizing Hospitalization Cost for Term Newborns in Intensive Care: A Multi-Center Analysis Across U.S. Children’s Hospitals
This multi-center retrospective study of 45,738 term newborns at U.S. children's hospitals reveals that while non-neonatal ICU admissions represent a minority of encounters, they account for a quarter of the $912 million in total costs, which are primarily driven by medical complexity and illness severity rather than the specific ICU setting.

Imagine the hospital as a giant, bustling airport terminal. Most babies arrive here for a quick, smooth landing: they are born, they cry, they get a check-up, and they head home with their parents. This is the "economy class" of newborn care—routine, predictable, and relatively inexpensive. But sometimes, a baby needs to be rerouted to the "VIP lounge" or the "emergency hangar." These are the Intensive Care Units (ICUs), where the most complex, high-stakes medical care happens. For decades, we knew a lot about the "VIP" passengers who were born too early (premature babies), but we didn't have a clear map of the costs and reasons for the "full-term" babies who also end up in these high-security zones. Are they there because they are sick? Because they need surgery? Or just because they need a little extra help? Understanding the price tag of this high-acuity care is like knowing the fuel cost of a rocket ship; it helps hospitals decide how to build better engines and where to spend their money to keep everyone safe.
This paper acts as a massive financial detective story, looking at over 45,000 full-term newborns (babies born after 37 weeks) who were admitted to intensive care at 42 different children's hospitals across the United States between 2022 and 2024. The researchers wanted to answer two big questions: What are the most common reasons these healthy-term babies end up in the ICU, and how much does it actually cost to keep them there? They split the data into two main "luggage compartments": the Neonatal ICU (NICU), which is the standard high-tech nursery for newborns, and the "non-neonatal" ICUs (like pediatric or cardiac ICUs), which are often used for babies with very specific, complex problems like heart defects.
The findings reveal a surprising twist in the story. While the vast majority of these babies (about 92%) went to the standard NICU, a small group (only 8%) went to the other, more specialized ICUs. However, this tiny 8% group was responsible for a whopping 25% of the total cost—roughly $912 million out of the $3.7 billion total bill. It's like a small group of travelers buying first-class tickets that cost as much as the entire economy section combined. The main driver for these sky-high costs wasn't just the baby's age or where they were born, but how "complex" their medical needs were. Babies with four or more chronic conditions cost six times more than those without any.
The study also broke down exactly where the money went. In both types of ICUs, the biggest chunk of the bill (the "room and board") was simply for the baby to stay in the hospital bed, eat, and be monitored. This makes up the bulk of the expense, much like the rent on a house is usually the biggest monthly bill. The researchers found that the most expensive diagnoses were often surgical, such as heart defects or issues with the diaphragm, which can cost over $100,000 per baby. Interestingly, the most common reason for admission was simply labeled "Liveborn," meaning the baby was born but needed extra care without a specific diagnosis attached yet; this single category accounted for a third of all hospitalizations and a quarter of the total cost, though the researchers noted this might be a bit of a "catch-all" label that hides some details.
Ultimately, the paper suggests that the cost of caring for these babies is driven less by who they are (like their race or gender) and more by what they need (how sick they are and how many complex conditions they have). The authors point out that while we have a good handle on the costs for premature babies, this study provides a crucial, up-to-date map for the full-term babies who need intensive care. It shows that while most of these babies are in the NICU, the ones who need the most specialized, surgical care in other ICUs are the ones driving the biggest price tags. This information helps hospital leaders understand that to save money and improve care, they need to look at the specific medical complexity of each baby, rather than just the type of room they are in.
