Introduction

Type 1 cohort

The diagnosis validation process*, introduced for the first type 1 report (2019-20), has been repeated, and extended to include anyone extra who was identified by a specialist service as being on an insulin pump. Therefore the type 1 cohort used for this report will not be the same as the type 1 cohort used in the NDA Core Report 1 2020-21. The cohort used for this report consists of people:

  • recorded as being diagnosed with type 1 diabetes within the 2020-21 NDA core audit
  • aged 19 years and over
  • prescribed insulin treatment consistent with 1 of the following regimens between the period 01 January 2020 to 31 March 2021:
    • Insulin pump
    • Basal-bolus
    • Fixed mix
  • or on an insulin pump according to a NDA submission from a specialist service

* This validation process should minimise the number of adults with type 2 diabetes inadvertently coded as type 1, but may exclude a few frail type 1 individuals who are treated compassionately with very simple insulin regimens.

  Type 1 Diabetes
Number Per cent
Total 223,600 -
GP practice and specialist service 85,305 38.2
GP practice only 137,765 61.6
Specialist service only 535 0.2

National Diabetes Audit Participation

Primary care participation stood at 99.3% in 2020-21 in England and Wales.

In all but 6 Clinical Commissioning Groups (CCGs) and Local Health Boards (LHBs) - 107 out of 113 - GP practice participation was 95% and over. Participation did not fall below 88% at any CCG/LHB.

108* specialist services participated in 2020-21 in England**.

• 51 services submitted both the NDA core dataset and the insulin pump dataset

• 9 services submitted only the insulin pump dataset

• 48 services submitted only the NDA core dataset

 

Altogether, there are 138 NHS Acute Trusts in England, some of which have more than 1 hospital providing specialist diabetes care. Specialist services generally take the lead in care for type 1 diabetes services and also often for younger people with type 2 diabetes. Their more comprehensive involvement is important as part of the drive to improve the poorer results for these patients.  

 

For more information on the level of participation in 2020-21 by CCG and LHB please see National Diabetes Audit, Report 1- Care Processes and Treatment Targets 2020-21, Underlying data. 

* 1 of the services had only a small number of adults with type 2 diabetes so is not included in this report

** 4 Welsh specialist services from 2 LHBs submitted insulin pump data to the NDA.

Specialist services participation

The map shows the percentage of adults with type 1 diabetes in each CCG for whom data was submitted by specialist services

• Only 39 CCGs had specialist services data submitted for at least half of the type 1 adults for whom there were primary care submissions
• Percentages ranged from only 1.5% in Stoke-on-Trent CCG to over 90% in North Tyneside CCG
