Abstract
OBJECTIVE
Overtriage (ie, delivering less severely injured patients via helicopter) is costly, raises safety concerns, and reduces efficiency of the trauma system. The Air Medical Prehospital Triage (AMPT) scoring system was developed to determine which trauma patients would gain a survival benefit by air transport. The objective of this study was to evaluate the AMPT scoring system as a method of reducing trauma overtriage when helicopter emergency medical services were used.
METHODS
A retrospective study of all scene trauma transports delivered by helicopter to 1 of 2 level 1 trauma centers was evaluated for 1) hospital stay less than 1 day and 2) failure to meet 1 of the following criteria for resource utilization: intensive care unit admission, an operative procedure within the first 24 hours, the need for blood products, Injury Severity Score ≥ 16, or death during hospitalization. Helicopter emergency medical services personnel recorded specific criteria from the Centers for Disease Control and Prevention (CDC) field trauma triage guidelines and AMPT that were met by transported trauma patients.
RESULTS
There were 244 patients in the study population. Eighty-one (33.2%) patients were discharged within 24 hours; 11 (13.5%) of these patients were positive using AMPT scoring, whereas 44 (54.3%) patients met 1 of the CDC criteria. Similarly, 141 (57.8%) patients failed to meet 1 of the level 1 resource criteria; 19 (13.5%) met the AMPT criteria for air medical transport, whereas 84 (59.6%) met 1 of the CDC criteria. Undertriage was 63.5% for AMPT and 20.2% for CDC based on resource utilization criteria.
CONCLUSION
The AMPT score reduced the number of patients who were inappropriately transported to a trauma center. However, this appeared to be at the expense of undertriage. Future studies should focus on developing a refined air medical-specific triage tool that has both low overtriage rates as well as lower undertriage rates.
