Australasian Diabetes Data Network (ADDN)

The ADDN project commenced in 2012 as a joint initiative between the Australia and New Zealand Society for Paediatric Endocrinology and Diabetes (ANZSPED) and Juvenile Diabetes Research Foundation (JDRF) Australia. The first phase of ADDN established a secure and centralised data repository hosted by the University of Melbourne, holding de-identified longitudinal demographic and clinical data for more than 5,000 children and adolescents with diabetes. The overall aim of the ADDN project is to facilitate research and improve the health of people with diabetes.

In 2016 the Australian Diabetes Society (ADS) joined ANZSPED and JDRF Australia for the second phase of ADDN which expanded the number of paediatric centres and extended recruitment to include adult centres. With this, ADDN extended its data capture and provide richer and more complete information about the natural history, clinical progression and most effective treatment regimens for all people living with type 1 diabetes. In Phase two, the focus shifted from development to improving data integrity, quality and overseeing use of the data for research.

Data collected by ADDN has enabled, for the first time, to conduct longitudinal research across paediatric and adult diabetes services. It will be possible to identify treatment strategies for type 1 diabetes that provide the best long-term outcomes, as well as enabling researchers to determine whether patients are eligible for clinical trials.  ADDN publishes benchmarking reports twice annually to support participating centres in their quality improvement efforts.

ADDN will commence Phase 3 in the second half of 2021. The appointment of a Medical Director will lead ADDN’s strategic plan to capture data on all young people with diabetes and to understand how to improve treatment and management of type 1 diabetes over the lifetime.

Data are accessible to researchers within strict ethical and governance boundaries.
