Abstract

PURPOSE
A secondary triage tool for pediatric trauma patients, "modified pediatric trauma score (mPTS)" was introduced to predict high risk trauma.
METHODS
Pediatric trauma patients (≤15 years) presenting to the Pusan National University Hospital trauma center emergency department were analyzed retrospectively. The patients were classified into high risk and low risk groups. The high risk group was assigned an Injury Severity Score ≥12, death, intensive care unit admission, or urgent intervention (intubation, closed thoracostomy, emergency angiography and embolization, emergency surgery). The airway, blood pressure, fractures, level of consciousness, and external wounds were evaluated and the mPTS was calculated.
RESULTS
One hundred seventy-seven patients were enrolled in this study. The mPTS had a sensitivity, specificity, positive predictive value, and negative predictive value of 88%, 54%, 60%, and 85%, respectively. Overtriage and undertriage was 39% and 14%, respectively. The mPTS missed 6 high risk patients and all 6 patients were abdominal injury patients. The mPTS was modified to include an abdominal physical examination and/or focused assessment with sonography for trauma. The newly developed scoring system was called the extended mPTS (E-mPTS). The E-mPTS had a sensitivity of 98% and negative predictive value of 98%. The safe level of overtriage (38%) was maintained.
CONCLUSION
mPTS was applied to the patients and the undertriage rate was too high. The extended mPTS improved undertriage to 2% while maintaining the overtriage rate at a safe level. The E-mPTS is expected to have a resource saving effect when used as a pediatric trauma team activation standard.
