Traumatic injury is a major burden in global healthcare systems, ranking among the leading causes of morbidity and mortality worldwide.1 Patients are first encountered at the pre-hospital scene by providers of varying levels of expertise, such as emergency medical technicians (EMTs) and paramedics, who provide temporizing measures while patients are transported to receiving hospitals to receive definitive care.2 Ultrasound is an ever-improving medical imaging modality which is increasingly portable, low cost, and provides diagnostic imaging rapidly without the harmful effects of radiation. The objective of this study is to determine whether introduction of prehospital ultrasound (PHUS) for use on ground ambulances by prehospital providers in order to improve choice of destination hospital and aid in needle thoracostomy for tension pneumothorax will have a positive impact on mortality rate of trauma patients in an urban EMS environment.
In the proposed study, trauma patients in the city of Boston, Massachusetts receiving care from Boston Emergency Medical Services (EMS) prehospital providers will be recruited over a 12-month period with a minimum goal of 2,500 patients in total. Emergency responses coded as trauma by EMS dispatch will be randomized at a 1:1 ratio to either utilize PHUS or to refrain from utilizing PHUS. A z-test will be used to analyze primary outcome of 30-day mortality rate in patients who receive PHUS care as needed compared with patients who do not receive PHUS care. Study data will be collected directly from Boston EMS Electronic Medical Record (EMR).
This study will be the first of its kind to randomize at the patient level, and the first to investigate a major clinical outcome of ultrasound in prehospital medical care: 30-day mortality. Point-of-care Ultrasound is an intriguing diagnostic modality that is becoming increasingly feasible in the prehospital environment, and may improve outcomes in trauma patients. Current studies provide convincing evidence for the diagnostic accuracy of these devices, especially in evaluating hemoperitoneum and pneumothorax. If an improvement in mortality rate of patients treated with prehospital ultrasound (PHUS) is demonstrated, this will be convincing evidence for the implementation of PHUS in ground ambulances and air medical services across the United States and worldwide.
