What this trial studies

The Hong Kong arm of the International Severe Asthma Registry will retrospectively and prospectively collect standardized clinical data from adults with severe asthma at participating centers. Data collection uses an annualized core dataset with optional enhanced variables, consistent coding, and standardized response options to ensure comparability. All clinical information will be anonymized before being pooled for analysis. The dataset will be used to track treatment responses, exacerbations, and health service use to inform future research and care improvements.

Why it matters

Potential benefit: If successful, the registry could help clinicians better understand severe asthma patterns and improve treatment decisions and clinical guidelines for patients.

How similar studies have gone: International severe asthma registries, including ISAR, have previously generated useful real-world evidence that has informed treatment patterns and guideline development.
