All 444 GP practices in Wales have participated in the 2015-16 data collection for the National Diabetes Audit (NDA), a voluntary collection which gives GPs, LHBs and Cluster Networks the opportunity to plan diabetes care in response to local needs and compare service delivery, treatment effectiveness and outcomes of care.
Data extraction in Wales is centrally coordinated with Audit+, the GP data quality, audit and reporting software tool delivered and supported by the NHS Wales Informatics Service.
Last year, Wales had 97.3% participation compared to England's 54.9%.
The NDA is the one of the largest annual clinical audits in the world, integrating data from both primary and secondary care sources, making it the most comprehensive audit of its kind.
