Sepsis kills nearly 1 in 5 hospitalized U.S. children, study reveals

A new national study has highlighted the persistent threat of sepsis among hospitalised children in the U.S. Published in JAMA, the research shows that nearly one in five pediatric hospital deaths is tied to the condition. Despite medical advancements, sepsis remains a leading cause of mortality in young patients, with little change in its impact over recent years.

The study examined 3.9 million pediatric hospital stays from 2016 to 2023, drawing data from hundreds of U.S. hospitals. Researchers applied a newly developed surveillance tool, the Pediatric Sepsis Event (PSE), to track cases consistently. This framework adapts the CDC's adult sepsis monitoring system for children, relying on objective clinical data from electronic health records.

Sepsis complicates about 1.3% of all pediatric admissions, meaning roughly one in seventy-five hospitalised children develops the condition. More than 10% of these cases prove fatal, with over 1,800 children dying annually before discharge. The study also found that many infections begin during hospitalisation, and these cases carry a higher risk of death. Despite increased awareness and improved treatments, the incidence and mortality rates of pediatric sepsis remained stable between 2016 and 2022. The PSE definition now provides a standardised way to identify cases, helping hospitals compare outcomes and target quality improvements.

The findings underscore sepsis as a critical issue in pediatric care, accounting for a significant share of hospital deaths. With the PSE framework in place, healthcare providers can better track trends and refine interventions. The goal is to reduce the burden of a condition that still claims thousands of young lives each year.
