Findings from the outcome evaluation of the All-Wales Diabetes Prevention Programme

This short report, published by the Evaluation Team within Public Health Wales, investigates the impact of the AWDPP on blood sugar levels and associated glycaemic categories (normoglycaemia, pre-diabetes, and diabetes). The evaluation used linked service data and routine healthcare records held within the Secure Anonymised Information Linkage (SAIL) databank ​(9–13)​. The evaluation employed a stepped wedge design, comparing outcomes for nearly 2,000 individuals offered the AWDPP with close to 1,500 people identified as at risk of 2 diabetes who received care as usual prior to the programme’s introduction.
