How it works
At the TrEAT Registry, each Partner Clinic owns their own data, and any use of data from a Partner Clinic for research purposes is subject to the Partner Clinic’s consent. Partner Clinic representatives are invited to co-design and co-author publications that use their clinic data, and may lead and supervise research themselves.
The TrEAT Registry provides infrastructure that can support program evaluations, and recently was used to scaffold the clinical and economic evaluations of Australia’s first residential treatment program for eating disorders, Wandi Nerida.

Research News
TrEAT Registry Awarded $2 Million MRFF Grant to Transform Eating Disorder Care
We are thrilled to announce that the TrEAT Registry has been awarded a $2 million Research Data Infrastructure grant from the Medical Research Future Fund (MRFF) to support a landmark national project running from 2025 to 2029.
Led by a the TrEAT Registry team of researchers, clinicians and client and carer representatives, this project will expand the TrEAT Registry into Australia and New Zealand’s first bi-nationally representative Clinical Quality Registry (CQR) for eating disorder treatment. The initiative will build a secure, scalable, engaging and innovative digital infrastructure with to monitor treatment outcomes, support clinical decision-making, and inform policy reform.
The project will unfold in three phases:
- Phase 1: Co-design and national implementation of a digital registry platform in collaboration with clients, carers, clinicians, researchers, and policymakers.
- Phase 2: Evaluation of the Medicare Benefits Schedule (MBS) items for eating disorders, including cost-effectiveness and equity of access, and exploring potential linkage with the ANZAED Credentialing System.
- Phase 3: Development of world-first clinical prediction models to guide personalised treatment selection for young people with eating disorders.
This work will directly support the Australian Government’s priority to develop CQRs in mental health and will serve as a model for other mental health conditions. With over 80% of TrEAT clients experiencing eating disorder onset in youth, the registry’s expansion promises to significantly improve outcomes for this priority population.
We thank our partners across Australia and New Zealand for their continued support and collaboration. To find out more about the project, reach out to lead investigator, Deb Mitchison.
