Shortness of breath (dyspnoea) is a terrifying symptom experienced by patients and is a common reason for presentation to Emergency Departments. There are a wide range of causes including flair up due to chronic conditions such as asthma, heart failure, chronic lung disease or liver or kidney failure. Acute conditions such as a collapsed lung, chest infection (including pneumonia), trauma (including fractured ribs), airway blockage or an allergic reaction can also be the cause.
There is significant knowledge about patients who are admitted to hospital with common causes, however there is little conclusive information about Dyspnoea as a symptom, the distribution of causes, the proportion of patients requiring admission and whether treatment complies with evidence-based guidelines.
A recent pilot study in Europe found that 53 per cent of patients had a respiratory cause for symptoms, 22 per cent had a cardiac cause, and 15 per cent had both cardiac and respiratory components. Almost two-thirds were admitted to hospital with over one-third discharged from ED. However, in many ways, the study raised more questions than it answered. The study was also too small to comment on adherence to evidence-based guidelines.
For that reason, a larger EuroDEM (digital elevation model) study is planned for 2014. The study will be complemented by the Australia, Asia and New Zealand Dyspnoea Departments of Emergency Medicine (AANZDEM) which will collect data from a different region with different systems of care. It will focus on the range of causes, variation over seasons and geographical areas, and compliance with recommended treatments.READ MORE
