Prehospital Transport for Pediatric Trauma: A Comparison of Private Transport and Emergency Medical Services.

OBJECTIVES: We describe the demographics of pediatric patients with trauma transferred using private transport (PT) versus emergency medical services (EMS) and evaluate the potential impact on their treatment and outcome. METHODS: We accessed data from our national trauma registry, a prospectively collected database. Data were extracted on all patients with trauma admitted to our institution between January 2011 and June 2013, with injury severity score (ISS) higher than 8. We categorized unstable injuries as head injuries, spinal injuries, or proximal long bone fractures. Major trauma was defined as the presence of any of the following: ISS of 16 or higher, intensive care unit (ICU) admission or death. RESULTS: Ninety children were studied, including 27 major trauma and 66 unstable injuries; 69 patients (77%) used PT. Most patients with major trauma (17/27, 63%) and unstable injuries (50/66, 76%) used PT. Compared with EMS patients, PT patients were younger, smaller, took longer for emergency department physician review and stayed longer in the emergency department. Rates of ICU admission were similar in both groups, but length of stay in ICU and total hospital stay were shorter in the PT group despite similar proportions of major trauma and unstable injuries as well as median ISS. Each group had 1 mortality. CONCLUSIONS: Most children with major trauma and unstable injuries were brought by PT, risking deterioration en route. Nevertheless, this does not seem to translate to worse outcomes overall.

Pedestrian injuries in children: who is most at risk?

INTRODUCTION: This study evaluates the demographics of paediatric pedestrian injuries with the aim of identifying the group of children who is most vulnerable and the risk factors for major trauma (MT). METHODS: Data was extracted from the integrated trauma system of a regional paediatric referral hospital. All paediatric cases involving road traffic accidents from January 2011 to December 2013 were studied. Demographics, injury mechanism, treatment and outcome were evaluated. Patients were categorised as MT or non-MT (NMT) based on their Injury Severity Score, admission to the intensive care unit, type of surgery (e.g. life/limb-saving) and death. Data analysis was done using nonparametric tests and Fisher's exact test. RESULTS: A total of 261 children were admitted for pedestrian injuries during the study period. The median age was ten years (range 14 months-16 years) and the median weight was 42.4 (range 8.6-93.7) kg. Half (i.e. 50.2%) of the children were primary-schoolers. The majority of the accidents occurred on roads (i.e. 83.1%), between 12 pm and 6 pm (i.e. 52.8%). Among the 261 children, 177 (67.8%) were unaccompanied by an adult at the time of the accident; 17 (6.5%) children sustained MT, while 244 (93.5%) suffered NMT. MT patients were more likely to have lost consciousness (p < 0.001) and been flung (p = 0.001). CONCLUSION: Most paediatric pedestrian injuries involved primary-schoolers walking home from school unaccompanied by adults. This information should inform future road safety campaigns. Being flung and loss of consciousness predicted MT in children who sustained pedestrian injuries.

Pediatric trauma team activation: are we making the right call?

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.
