Creating and utilising a Wales Asthma Observatory to support health policy, health service planning and clinical research

My project aimed to maximise the benefit of routine data for asthma research and surveillance.

Asthma is one of the commonest life-long diseases in Wales with significant clinical and financial burden. In order to better understand the disease impact and improve the service, up-to-date nationwide data on asthma are needed.

I developed Wales Asthma Observatory as a data-intensive platform for asthma research and surveillance. I used large amounts of linked, anonymised electronic health record (EHR) data in the Secure Anonymised Information Linkage (SAIL) Databank of Wales. The Observatory includes research-ready variables that describe several asthma definitions and outcomes.

I focused on the challenge of identifying people with asthma using routine data. I highlighted variations and suboptimal reporting on how asthma has been defined and assessed in routine data studies. In the Observatory, I used clustering methods to understand the underlying structure of the Welsh population in order to identify people with asthma.

I also demonstrated the Observatory utility for health policy by investigating inequalities of asthma care in Wales. 

The Observatory can support a wide range of asthma studies including testing new treatment strategies, up-to-date monitoring of asthma outcomes and burden across Wales, and planning and evaluation of asthma services.

About me

My research interests are asthma epidemiology, clustering, latent class analysis, analysis of linked health data, clinical coding systems, and research reproducibility.
