Insights

Combining the Cribari Matrix (CM) and Need For Trauma Intervention (NFTI) tools accurately identifies pediatric trauma undertriage. This combined approach reveals undertriaged children face worse outcomes, including higher mortality and costs.

Area of Science:

  • Trauma Surgery
  • Pediatric Emergency Medicine
  • Health Services Research

Background:

  • The American College of Surgeons (ACS) Committee on Trauma aims for undertriage (UT) rates below 5% to improve survival.
  • The traditional Cribari Matrix (CM) may overestimate UT, while the Need For Trauma Intervention (NFTI) tool offers a more accurate assessment in adults.

Purpose of the Study:

  • To evaluate the efficacy of combining the CM and NFTI tools in accurately identifying undertriage in pediatric trauma patients.
  • To compare the UT identification capabilities of CM alone versus the combined CM and NFTI approach.

Main Methods:

  • A retrospective review of undertriage rates using both CM and NFTI criteria was conducted.
  • Univariate analysis compared outcomes such as surgical management, transfusion needs, ventilator days, and length of stay (LOS) between CM, NFTI, and combined CM/NFTI groups.

Main Results:

  • Undertriage rates were 8.2% with CM and 4.6% with NFTI. The combined CM and NFTI approach yielded a UT rate of 2.7%.
  • Pediatric patients identified as undertriaged by the combined CM and NFTI criteria experienced significantly longer ICU and hospital LOS, higher mortality rates, and increased hospitalization costs.

Conclusions:

  • The combination of CM and NFTI provides a more accurate identification of undertriage in pediatric trauma patients compared to either tool used alone.
  • Undertriaged children face increased mortality, morbidity, and healthcare costs, highlighting the need for refined trauma activation criteria.
