International Severe Asthma Registry_Hong Kong

To ensure the care of people with severe asthma continues to improve, it is essential we have detailed information on the health and treatment of as many people with the condition as possible. The purpose of the registry is to gather this information and track the progress of patients and how well they are responding to treatment. Medical research using data from the registry will provide a better understanding of asthma and help to develop and improve the care and treatment for patients with asthma.

Detailed protocol can be referred to the reference in this trial registration (International severe asthma registry [ISAR]: protocol for a global registry).
