Diabetes Prevention Programme
Introduction
The NHS Diabetes Prevention Programme (DPP) offers courses of intervention to people who are identified with a high risk of developing type 2 diabetes in order to reduce that risk.
People are eligible1 for referral to the DPP if they have had a glycaemic test result in the appropriate range (HbA1c: 42 – 47 mmol/mol; fasting plasma glucose: 5.5 – 6.9 mmol/l) within the last 24 months (this was 12 months, but has been extended during the Covid-19 pandemic). Not everyone with an NDH diagnosis will be eligible to be referred to the DPP; some will have a diagnosis from prior to the last 24 months, without test results in the appropriate range over the last 24 months.
Some people with a GP recorded DPP offer do not have a provider record of their DPP referral, and some people with a provider recorded DPP referral are not recorded on their GP system with a GP diagnosis of NDH.
559,770 of people with a current GP record of NDH, have been offered DPP and not declined it, according to their GP record.
Of people with a recent4 NDH diagnosis (from Jan 2020 onwards), 85 per cent had a blood glucose reading in 2020-21 that meant they could be referred to the DPP.

Diagnoses
Table 5: People with a DPP referral1, by GP recording of diabetes or non-diabetic hyperglycaemia, 2020-21, England.
| Diagnosis in GP record | Number | Per cent |
| Total | 663,020 | |
| - NDH diagnosis present | 408,065 | 61.5 |
| - Diabetes diagnosis present | 13,065 | 2.0 |
| - No diagnosis present | 241,890 | 36.5 |
DPP providers record information about the people who have been referred to them, and how people interact with the service. Since the DPP began, more than 1 in 3 people referred had no GP-recorded NDH diagnosis associated with elevated blood glucose levels.
1. People included: with a known valid NHS number; registered at a GP practice that participated in NDA 2020-21, with a referral to the DPP programme as recorded by one of the DPP providers.
2. People included: with a known valid NHS number; registered at a GP practice that participated in NDA 2020-21, with a referral to the DPP programme as recorded by one of the DPP providers.

(2i) Sex and ethnicity are only recorded at initial assessment. People who have been referred but not attended an initial assessment are not included in these breakdowns.
(2ii) BMI as recorded during 2020-21, as part of a referral that was open during 2020-21.
