Conditions
Brief summary
Point-of-care ultrasound in patients with dyspnoea has been shown to alter patient treatment and the time to correct treatment when performed in emergency departments. In Denmark, physician-staffed ambulances are sent to citizens with severe ABCD symptoms including dyspnoea. Hence, there is a potential for correct diagnostics and appropriate treatment already in the citizens' own home or en route to the hospital. This study aims to evaluate the clinical performance of prehospital point-of-care ultrasound in patients with dyspnoea.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Sensitivity for diagnosing heart failure | From initial citizen contact to end of ultrasound examination within 15 minutes | Change in sensitivity for diagnosing heart failure when adding point-of-care ultrasound to the clinical examination |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Sensitivity, clinical exam | From initial citizen contact and within a time-span of 15 minutes | Sensitivity of clinical examination for for diagnosing heart failure. Held up against a post-hoc expert panel statement. |
| Sensitivity, Ultrasound examination | From initial citizen contact and within a time-span of 15 minutes | Sensitivity of clinical examination supplemented with ultrasound scan for diagnosing heart failure. Held up against a post-hoc expert panel statement. |
| Treatment changes in medicine caused by ultrasound examination | From initial citizen contact and within a time-span of 15 minutes | Changes in medical treatment including diuretics, nitric oxide, bronkodilation and steroids caused by the addition of an ultrasound scan |
| Treatment changes in ventilation caused by ultrasound examination | From initial citizen contact and within a time-span of 15 minutes | Treatment changes ventilatory strategy including nasal cannula oxygen therapi, face mask or non-invasive positive pressure ventilation caused by the addition of an ultrasound scan |
| Triage changes caused by ultrasound examination | From initial citizen contact and within a time-span of 60 minutes | Change in the department or hospital that the patient is sent to as a cause of an ultrasound scan |
