Point-of-care Ultrasound in Prehospital Dyspnea

Completed

• Conditions: Dyspnea

• Registration Number: NCT03905460
• Lead Sponsor: University of Aarhus

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.

Primary Outcome Measures

Name	Time	Method
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 Outcome Measures

Name	Time	Method
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
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.
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
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.
