This German retrospective study compared the prehospital use of ultrasound by trained paramedics and compared their findings to in-hospital diagnosis and image results. The authors found: 

“Diagnostic accuracy, defined as the concordance between prehospital POCUS-based working diagnoses and final in-hospital diagnoses, was particularly strong for lung ultrasound (pneumothorax, pulmonary edema, pneumonia and pleural effusion; sensitivity 91.7%, specificity 100%) and eFAST (sensitivity 100%, specificity 96.5%), while for the abdominal ultrasound examinations, the specificity was 70% and sensitivity was 71.43%.”

This study sets the stage for future prospective work looking at prehospital US use by paramedics.
