Abstract
Introduction A regionalized trauma system must be tailored to the trauma epidemiology and the
trauma care resources of the population it serves. Pediatric trauma system in Singapore
differs from others because of its geographic compactness and relatively low incidence
of severe trauma. The scarcity of polytrauma highlights the need of a reliable screening
system to identify injured children who necessitate urgent transport to emergency
department (ED) with pediatric resuscitation capacity as well as activation of trauma
team upon their arrival. In this study, the validity of Pediatric Trauma Score (PTS),
Glasgow Come Scale (GCS), and respiratory rate (RR) in identifying pediatric patients
with major trauma and receipt of resuscitation is evaluated.
Patients and Methods After obtaining Institutional Review Board approval, a retrospective analysis was
performed using data obtained from our trauma registry between January 2011 and December
2012. Information pertaining to the demographics, causative mechanism, and injury
description, resuscitation, admitting disciplines, surgical intervention, and outcome
were analyzed. The sensitivity and specificity of PTS, GCS, and RR to predict outcomes
of interest are calculated.
Results A total of 92 patients were recruited. From the 92 patients, 26 sustained major trauma,
and 21 patients received ED resuscitation. The mean age was 4 years 9 months. Sensitivity
and specificity of PTS ≤ 8, GCS ≤ 10, and abnormal RR for predicting major trauma
were 61.5, 77.3; 26.9, 100; and 53.8, 60.6%; respectively. When the reliability to
identify patients received ED resuscitation was evaluated the sensitivity and specificity
of PTS ≤ 8, GCS ≤ 10, and abnormal RR were 90.5, 83.1; 28.6, 98.6; and 76.2, 66.2%;
respectively.
Conclusion The parameters of PTS need to be further refined to improve its accuracy and minimize
the undertriage rate. If a combined physiologic and anatomic scoring system such as
PTS is used, other physiologic parameters such as GCS and RR may become redundant.
The evaluation of the validity of PTS, GCS, and RR in predicting pediatric major trauma
indicated poor reliability.
