Formative Process and Value-Based Evaluation of the Wave 1 Roll-Out of the All Wales Diabetes Prevention Programme

• All Wales/National

This report presents a formative process and value-based evaluation of the Wave 1 roll-out of the All Wales Diabetes Prevention Programme (AWDPP) funded by Public Health Wales (PHW)

In Wales, the national diabetes prevention programme based on a brief lifestyle intervention was developed following pilot work conducted in the Afan Valley and North Ceredigion primary care clusters. The AWDPP intervention consists of systematic identification of adults at risk of developing Type 2 Diabetes Mellitus (T2DM) identified through HbA1c measurement of between 42 to 47 mmol/mol, i.e., prediabetes range and offering a 30-minute person-centred lifestyle conversation (delivered face-to-face, by phone or by video call) focused on diet and physical activity levels. The intervention has been designed to be delivered by a designated Healthcare Support Worker (HCSW) who has received essential training to facilitate delivery of the AWDPP intervention. Service users may then be referred on to existing health promotion / lifestyle modification programmes such as the National Exercise Referral Scheme (NERS), weight management services, or the Let’s Prevent Diabetes interactive digital education programme.

The national roll-out of the AWDPP is led by the Primary Care Division, Public Health Wales (PHW) and delivered by local Health Board community dietetic teams, through primary care clusters within each of the seven Health Boards across Wales.
