NCT03000491

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.
