What does the high risk strategy of prevention have to offer? The example of the NHS Diabetes Prevention Programme
Diabetes Prevention Programmes aim to identify people at high risk of developing type 2 diabetes, and help these people reduce their risk through behaviour changes, leading to weight loss. They have been implemented internationally, and trials from several countries have demonstrated their effectiveness at reducing diabetes incidence.
The NHS Diabetes Prevention Programme is a nine-month behaviour change programme that was launched in England in 2016, with a digital pathway being introduced in 2019. Although the programme has reached over 500,000 people to date, it has received criticism for taking a “high-risk” approach to prevention, rather than targeting the whole population (the “population” approach).
I will present selected findings from research that has been undertaken over the past five years by the NIHR-funded DIPLOMA research programme (Diabetes Prevention – Long Term Multimethod Assessment). I will focus on the extent to which the multiple independent providers deliver the NHS Diabetes Prevention Programme with fidelity to the evidence base. I will also consider where and why there is variation between providers, and where low fidelity and variation occurs. I will consider when and how this low fidelity matters.
The presentation will consider what are the benefits of the high-risk approach based on this NHS programme, and potential drawbacks compared to a population approach. I will highlight where the DIPLOMA team have worked with NHS-England to improve the NHS Diabetes Prevention Programme, informed by the research evidence we have produced. I will conclude with identifying where there is a need for better evidence to allow future Diabetes Prevention Programmes to have more impact.
