Nearly 10 to 12 percent of US live births end up in the NICU every year, translating to more than 500,000 infant admissions in 2021 alone. Costs can run $3,500 to $5,000 per day, while outcomes flip sharply by gestational age, with term babies staying around 5 to 7 days and extremely preterm infants often far longer. Let’s look at how those admission rates, length of stay, and survival numbers line up across weeks, sizes, and countries.
Key Takeaways
- Approximately 10-12% of live births in the US require NICU admission annually.
- In 2021, over 500,000 infants were admitted to NICUs in the US.
- Globally, around 15 million preterm births occur yearly, many needing NICU care.
- Average US NICU cost per day $3,500-$5,000.
- Annual US NICU expenditure >$25 billion.
- Preterm <28 weeks cost >$500,000 per infant.
- Average NICU length of stay for preterms is 40-60 days.
- Term infants average 5-7 days in NICU.
- <28 weeks gestation LOS >90 days.
- NICU mortality for term infants is <1%.
- Overall NICU mortality rate is 5-10%.
- Preterm <28 weeks mortality is 10-20%.
- NICU survival rates for extremely low birth weight infants (>500g) exceed 80% in high-resource settings.
- Preterm infants at 24-25 weeks have 60-70% survival rates.
- Overall NICU survival is 90-95% in developed countries.
About half a million babies enter US NICUs each year, where most survive, though costs and risks are high.
