Brief summary

Background: Acute dyspnoea is a common symptom in prehospital emergency medicine. As ultrasound gained in importance for diagnosis in patients with acute respiratory distress, it plays even a role in the prehospital setting. However, prehospital emergency ultrasound (PEU) remains challenging and requires knowledge and skills. New prehospital ultrasound devices offer the possibility for tele-supervision. The impact of tele-supervision of PEU in patients with acute dyspnoea is unclear. Objective: This prospective observational study aims to evaluate the effect of PEU with tele-supervision on diagnosis, treatment strategies and cognitive load in comparison to PEU without tele-supervision in patients with acute dyspnoea. Methods: In total 350 prehospital emergency patients with acute dyspnoea will be included in this study. Patients will be observed in two groups. In group 1 PEU will be performed with tele-supervision, whereas in group 2 PEU will be performed without tele-supervision (tele-supervision not available).

Design outcomes

Primary

Measure	Time frame	Description
Accuracy of prehospital diagnosis after PEU in relation to the (correct) in-hospital diagnosis	through study completion, an average of 1 year	The aim of this study is to compare the accuracy of a prehospital emergency ultrasound (PEU) done with or without tele-supervison in patients suffering from acute dyspnoea and evaluate the accuracy of the diagnosis in relation to the (correct) in-hospital diagnosis.

Secondary

Measure	Time frame	Description
Agreement of diagnosis before PEU and after PEU	through study completion, an average of 1 year	Is there an agreement between the diagnosis before performing the prehospital emergency ultrasound (PEU) and after performing it.
Duration of prehospital emergency ultrasound (PEU)	through study completion, an average of 1 year	Duration of prehospital emergency ultrasound (PEU)
