Change to inclusion of drug prescription and diabetic ketoacidosis (DKA) data for Wales
In the Interactive data visualisation published on 16 June 2022 Wales drug prescription data was not included in the diabetes diagnosis validation process. In v2.0 of the visualisation this data has been included resulting in a larger cohort used for the analysis, particularly for Wales. For further details on the diagnosis validation process see main report.
In addition, v2.0 no longer includes analysis on DKA hospital inpatient admissions for Wales. This is because it was only possible to obtain data NHS hospital admission data from hospitals in England and therefore any DKA hospital inpatient admission results for Wales would not have been representative of diabetes care in Wales.

Changes to NDA reporting
NHS England are currently reviewing the routine production of NDA State of the Nation reports. Please note that data will still be released via dashboards and standalone data files whilst this review is being conducted.
To help inform this review we would be grateful if users can provide feedback on their use of the State of the Nation reports using the feedback survey available in the ‘Related links' section of this page.

Insulin pump
Adolescents and Young Adults with type 1 diabetes on Insulin Pump
- A quarter of adolescents and young adults (24.5%) with type 1 diabetes were on an insulin pump at some point during the AYA period.
* Within the audit year.
Table 6: Number and percentage of adolescents and young adults with type 1 diabetes on an insulin pump in the National Paediatric Diabetes Audit (NPDA) and then on an insulin pump later in the National Diabetes Audit (NDA)*,**, England, 2017-21
| Diabetes services | Type 1 Diabetes | |
| Number | % | |
| Total on insulin pump in NPDA | 4,415 | - |
| On insulin pump in NDA | 3,615 | 81.9 |
| Not on insulin pump in NDA | 800 | 18.1 |
- 81.9% of adolescents and young adults who were on an insulin pump in paediatric services were later also on an insulin pump in adult services*.
* Recorded in their last audit year in NPDA as aged 15 to 25 years old at audit year start and being on an insulin pump, then recorded in the NDA as being on an insulin pump in a later audit year.
** Totals may not sum due to data suppression. See Additional Information for more details.
- A greater proportion of adolescents and young adults with type 1 diabetes on insulin pumps achieved a HbA1c level of less than or equal to 58 mmol/mol compared to those not on an insulin pump.
- This finding is consistent across all ages between 15 and 25 years.
* Based on latest HbA1c result in audit year.
** Within the audit year.
- Adolescents and young adults with type 1 diabetes were less likely to have high levels of HbA1c (i.e. greater than 86 mmol/mol) if they were on an insulin pump.
- This finding is consistent across all ages between 15 and 25 years.
- However the difference between those on insulin pumps and those not on pumps is more pronounced in younger and older ages.
* Based on latest HbA1c result in audit year.
** Within the audit year.
- Insulin pump treatment is associated with a lower median and mean HbA1c result.
* Based on latest HbA1c result in audit year.
** Within the audit year.
*** For a summary of the statistics see Appendix.
- Adolescents and young adults with type 1 diabetes were less likely to have single or multiple hospital inpatient admissions with a DKA diagnosis* if they were on an insulin pump.
- This is particularly so in younger years.
* Where an episode of DKA occurred at any time during the hospital admission. Admissions that start in the same year of diabetes diagnosis are excluded.
** Within the audit year.
