People are classified into moderate risk, high risk or those with possible type 2 diabetes depending on the fasting plasma glucose or HbA1c result. Those with a high-risk score meet the criteria for non-diabetic hyperglycaemia.
Individual risk factors should be discussed with those identified as moderate or high risk. People with modifiable factors should be shown how risks can be reduced through evidence-based lifestyle and behavioural change programmes (such as walking and structured weight loss schemes).
People at high risk should be invited to take part in at least 13 education and exercise sessions conducted over a minimum of nine months and have their blood glucose levels checked annually. Current providers of the NHS Diabetes Prevention Programme include Reed Momenta, WW (formerly Weight Watchers), Changing Health and Liva Healthcare.
The generic service specification can be accessed via NHS England. Training and accreditation of pharmacy teams to formally deliver the NHS Diabetes Prevention Programme can also be beneficial in tackling type 2 diabetes in the local population.
In May, the DPP confirmed that HbA1c point-of-care tests will no longer be undertaken on individuals referred to the service. This change is partly due to data showing that the results are less accurate than laboratory testing.
