Evaluation is a key element to the All Wales Diabetes Prevention programme and will be used to measure impact and inform future improvements. PHW’s Research & Evaluation Division are leading the evaluation of the All Wales Diabetes Prevention Programme through two separate approaches.
- To evaluate the outcomes of the All Wales Diabetes Prevention Programme, a modified stepped wedge approach has been proposed. The outcome evaluation will assess whether the intervention leads to a change in people’s HbA1c levels at their 12-month follow-up, and whether there is a difference in HbA1c for people who receive the intervention compared to those who had received usual care.
- To evaluate the process and value of the All Wales Diabetes Prevention Programme, a consortium between Swansea, Aberystwyth and Bangor Universities was chosen to undertake an independent assessment of what works, where and why. This will enable lessons to be learned during the initial Programme rollout, in order to inform the scaling of the Programme across Wales.
This learning will be achieved through the information gathered via interviews with patients and professionals, observations of intervention delivery, document analysis, and the collection of routine data from GP practices on intervention eligibility, invitation, uptake and follow-up. A value-based assessment will also be undertaken to assess the alignment of the All Wales Diabetes Prevention Programme against Welsh prudent health care principles.
