Background: Previous research reports that a small proportion of injured children are transported from the scene by emergency medical services (EMS). This study aimed to assess the proportions of injured children transported to trauma centers by different transportation modes and evaluate the effect of transportation mode on interfacility transfer rates.

Methods: We retrospectively reviewed data from the 2007-2012 National Trauma Data Bank (NTDB) to study trends of EMS versus non-EMS transport. Multivariable logistic regression was used to evaluate the association between transport mode and inter-facility transfer.

Results: There were 286,871 pediatric trauma patients in the 2007-2012 NTDB; 45.8% arrived by ground ambulance, 8.6% arrived by air ambulance, and 37.5% arrived by non-EMS. From 2007-2012, there was no significant change among each transportation mode. Among moderate to severely injured patients (ISS>15), 13.3% arrived by ground ambulance, 26.7% arrived by air ambulance, and 8.3% arrived by non-EMS; those who used EMS were significantly less likely to be transferred to another facility than patients who used non-EMS transport. Pediatric patients arriving by non-EMS to adult trauma centers were more often transferred than those arriving at mixed trauma centers (45.8% and 6.8%, respectively).

Conclusions: Over one third of US pediatric trauma patients used non-EMS transport to arrive at trauma centers. Moderate to severely injured children benefit from EMS transport and professional field triage to reach the appropriate trauma facility. Our study suggests that national efforts are needed to increase awareness among parents and the general public of the benefits of EMS transportation and care.
