Learning Health System for Asthma

Completed

• Conditions: Asthma

• Registration Number: NCT03000491
• Lead Sponsor: University of Edinburgh

Brief Summary

This study forms an initial phase of work aimed at developing a learning health system (LHS), whereby data relating to asthma is extracted from patient electronic health records (EHRs) across Scotland, analysed to explore variations in clinical practice and then shared with general practices to highlight any improvements that can be made so that they can better support people with asthma.

If successful, the investigators hope to progress to the main quality improvement phase involving an increased number of practices and then incrementally build this up to cover the whole of Scotland.

Detailed Description

The UK has amongst the highest rates of asthma in the world as well as some of the poorest health outcomes from asthma.

Investigations into asthma deaths in the UK have found that the way patients were managed in the time leading up to their death could be improved significantly and half of asthma deaths are potentially avoidable. For most people with asthma, symptoms can come and go and sometimes be erratic. To prevent these symptoms, there is a window of opportunity to intervene with the appropriate care. This window occurs between when someone experiences early symptoms like night cough or wheeze and when they experience a full-blown asthma attack.

Most people with asthma receive care primarily in their general practice. General practices have a history of using health information technology to care for their patients. The use of this technology over time has resulted in the creation of rich electronic healthcare data. Through this rich data there are opportunities to create a system whereby clinical management can be benchmarked and improvements highlighted.
