The impact of prehospital use of ultrasound by EMS: Diagnostic and interventional benefits
Keywords:
prehospital ultrasound, trauma management, emergency medical services, systematic review, diagnostic accuracyAbstract
Background: Prehospital care, particularly for trauma patients, is complex due to the unpredictable environments in which emergency medical services (EMS) operate. The integration of prehospital ultrasound (PHUS) offers potential improvements in trauma management, a leading cause of mortality among younger populations in the U.S. Aim: This systematic review evaluates the application of PHUS in trauma management, focusing on its diagnostic and interventional benefits when utilized by different provider types, including EMS professionals, physicians, and mixed teams. Methods: A comprehensive literature search was conducted across multiple databases, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The analysis used a PICO framework to compare ultrasound-assisted care with standard practices. A total of 16 studies were included for evaluation, assessing various ultrasound protocols and their impact on treatment decisions and outcomes. Results: The review highlighted significant variability in sensitivity and diagnostic accuracy among studies using PHUS. While the majority of studies involved physician-operated ultrasounds, limited research focused specifically on EMS professionals. Notably, the findings indicated that PHUS positively influenced treatment and transport decisions, although no studies directly addressed its effect on mortality rates.
