Many older persons present to the Emergency Department complaining of shortness of breath (Dyspnoea). This can be an important forewarning of heart failure, but is also present in many other conditions. In most cases, several bedside tests are carried out to identify those patients with heart failure. Despite these investigations, which include blood tests, electrocardiograph and chest x-ray, heart failure is initially misdiagnosed in up to one quarter of patients in the emergency department. This project focuses on secondary prevention of the complications of the disease caused by missed diagnosis.
Some European hospitals use bedside lung ultrasound as an adjunct to the above tests, claiming it improves recognition of heart failure, and should decrease the time to appropriate treatment. The European model of ultrasound practice is significantly different from the Australian model, and there is limited evidence supporting either model provided in the literature.
This is a multi-centre study following on from a successful pilot project. A safe, simple protocol has been tested in an Australian Emergency Department, in parallel to normal diagnostic strategies. To prove the protocol actually improves patient care, it now has to be tested as part of the diagnostic workup for breathlessness compared with the conventional diagnostic procedure.
