[3] The Adolescent Medicine at The Children's Hospital at Westmead seeks to improve the health and wellbeing of young people aged 12–24.

[4] In February 2023, a team of doctors at Westmead led by Joseph Elkadi, Catherine Chudleigh, and Ann M. Maguire published an article in the paediatric journal Children examining the developmental pathway and clinical outcomes of 79 transgender children who presented at the hospital's gender service, the conclusions of which are contested.

Their conclusions were widely repeated in numerous articles in conservative or right-leaning media outlets in Australia, citing "legal and safety fears" over gender-affirming healthcare.

[9] In a response letter dated 1 March 2023, AusPATH held that the Westmead study's authors displayed "significant bias" in their use of terminology and selection of supporting literature.

In particular, its use of the scientifically-unverified "Rapid Onset Gender Dysphoria" (ROGD) classification for study participants compromises the validity of the Westmead research, according to AusPATH.

The Westmead study's authors were also criticised for using "de-humanising" anti-trans language and for "pathologising" gender diversity in a discriminatory way in their article.
