Live Stream of Prehospital Emergency Ultrasound in Patients With Acute Dyspnoea

Study Overview
=================
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).

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Accuracy of prehospital diagnosis after PEU in relation to the (correct) in-hospital diagnosis | 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. | through study completion, an average of 1 year | 

Secondary Outcome Measures

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