International registries have provided valuable insight into care and outcomes of people with T1D. In Australia separate state based registries have existed for over 20 years. The National Diabetes Register (NDR) which sources data from state based registries, reports the incidence and prevalence of diabetes.

The ADDN Registry holds longitudinal de-identified data and was established to provide a national data source to foster collaborative research and improve clinical care. With the inclusion of adult diabetes centres, it is now possible for the ADDN Registry to report on Type 1 Diabetes patients from diagnosis as juveniles through to on-going treatment as adults.

Participating centres upload data to ADDN every 6 months. Comprehensive data validation rules and error reports have been implemented to ensure data quality.  More information on the methodology used within ADDN can be found here.

If you would like to enquire about using the data in ADDN for your research, please submit your enquiry using the form here.



  • Children and adolescents (≤ 18 years) :  diagnosis of either T1D, Type 2 diabetes (T2D), Cystic Fibrosis Related Diabetes (CFRD), Monogenic diabetes, Neonatal Diabetes and other rarer forms of diabetes.
  • Adults (>18 years) :  all adults diagnosed with T1D or adults with other types of diabetes who have transitioned from a participating paediatric diabetes centre.

Report of ADDN Diabetes Centres

Data currently available in the ADDN Registry has provided, for the first time, a snapshot profile of paediatric patients attending diabetes centres at the ADDN tertiary public hospitals.

The information contained in the following table represents data from the paediatric diabetes centres at following hospitals:

  • Children’s Hospital at Westmead, Sydney, NSW
  • The John Hunter Children’s Hospital, Newcastle, NSW
  • The Royal Children’s Hospital, Melbourne, VIC
  • The Women’s and Children’s Hospital, Adelaide, SA
  • The Princess Margaret Children’s Hospital, Perth, WA
  • The Lady Cilento Children’s Hospital, Brisbane, QLD


The information provided is correct as of the date indicated. While representative of patients attending the ADDN paediatric diabetes centres, it is not reflective of the entire juvenile (0 to 18 years) diabetes population in Australia. If you have any questions or want to know more about the data in ADDN, you can contact us here.
