Point-of-care Ultrasound in Prehospital Dyspnea

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.

Treatment and study plan

Point-of-care ultrasound

Diagnostic Test

Focused ultrasound of the heart, lungs and pleurae

Primary outcomes

  1. Sensitivity for diagnosing heart failure

    Time frame: 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 outcomes

  1. Sensitivity, clinical exam

    Time frame: 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.

  2. Sensitivity, Ultrasound examination

    Time frame: 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.

  3. Treatment changes in medicine caused by ultrasound examination

    Time frame: 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

  4. Treatment changes in ventilation caused by ultrasound examination

    Time frame: 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

  5. Triage changes caused by ultrasound examination

    Time frame: 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
