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.

Treatment targets
How many adolescents and young adults with type 1 diabetes achieve the National Institute for Health and Care Excellence (NICE) recommended treatment targets?
- 84.9% of adolescents and young adults aged between 15 and 25 years with type 1 diabetes had a valid HbA1c level recorded.
- The lowest average HbA1c level was found in adolescents and young adults with type 1 diabetes aged 15 years (median = 65.0; mean = 69.0).
- The average HbA1c level then increased with age until its peak at 20 years old (median = 73.0; mean = 76.8).
- After 20 years old the average HbA1c level of adolescents and young adults with type 1 diabetes decreased with age (at 25 years old: median = 69.0; mean = 73.1).
* Based on latest HbA1c result at age in years.
** For a summary of the statistics see Appendix.
- Adolescents and young adults with type 1 diabetes aged 15 years showed the highest rates of achieving HbA1c less than or equal to 58 mmol/mol and the lowest rates of having HbA1c greater than 86 mmol/mol.
- These rates decreased and increased respectively with age and reached their lowest and highest rates at the age of 20 years. The rates improved after the age of 20 but did not reach similar rates found in the younger age groups.
* Based on latest HbA1c result at age in years.
- Around 60% of adolescents and young adults with type 1 diabetes (59.7%) had their UACR measured between the age of 15 and 25 years****. Of those 85.1% had a UACR level recorded.
- The percentage of adolescents and young adults with type 1 diabetes with abnormal UACR levels was lowest at 15 and 16 years old.
- This percentage increased with age, particularly so between the ages of 16 and 21 years. This may be due to longer diabetes duration.
* Abnormal levels are above 2.5mg/mmol in males and above 3.5mg/mmol in females.
** As a percentage of adolescents and young adults with type 1 diabetes with a UACR date and level at age in years.
*** Based on latest UACR result at age in years.
**** Based on having a recorded UACR date on or after their diagnosis date.
***** Percentages may not add up to 100% due to data suppression. See Additional Information for more details.
