  2019-20 2020-21
Care process Number Per cent Number Per cent
Any glycaemic test 1,670,925 78.1 1,597,930 67.2
 - Fasting plasma glucose 101,425 4.7 65,305 2.7

1. People included: those registered at a GP practice that participated in NDA 2019-20 / 2020-21.

2. 2,140,090 people were recorded with non-diabetic hyperglycaemia in NDA 2019-20.

    2,378,485 people were recorded with non-diabetic hyperglycaemia in NDA 2020-21.

  • In 2020-21, fewer people with NDH were monitored for BMI and glycaemic testing.
  • However, despite the pressures of the COVID-19 pandemic, more than two-thirds of people with non-diabetic hyperglycaemia had a HbA1c or fasting plasma glucose test.

2 charts showing Patient monitoring within the audit period1,2, by CCG, GP-recorded non-diabetic hyperglycaemia (NDH), 2019-20 - 2020-21, England. 1 chart shows percentage of people who had a glycaemic test and 1 chart shows percentage of people who had BMI monitored.

1. People included: those registered at a GP practice that participated in NDA 2019-20 / 2020-21.

2. 2,140,090 people were recorded with non-diabetic hyperglycaemia in NDA 2019-20.

    2,378,485 people were recorded with non-diabetic hyperglycaemia in NDA 2020-21.

  • In 2019-20, the median level of glycaemic tests undertaken in CCGs was at 79%; in 2020-21 this was 66%.
  • In 2019-20, the median level of BMI measurements undertaken in CCGs was at 64%; in 2020-21 this was 45%.

1. People included: those registered at a GP practice that participated in 2020-21. 
2. 2,378,485 people were recorded with non-diabetic hyperglycaemia in NDA 2020-21.

  • 8 per cent of people diagnosed with NDH in 2020-21 did NOT have a glycaemic test done in the audit period.
  • People diagnosed with NDH in 2020-21 were more likely to have a BMI care process completed in the audit period – 59% – than people diagnosed earlier – 43%.
  • Overall, in 2020-21, people with NDH were more likely to have had their care processes if they were aged 65 and over.
  • There was relatively little difference in care processes across areas of different deprivation.
