The retrospective analysis will examine routinely collected clinical and outcome measures data including demographic, clinical, gender identity-related and healthcare resource use information. Data will be reported for each service and also compared between services. This study forms part of a wider programme of research investigating outcomes of gender identity in children (the Longitudinal Outcomes of Gender Identity in Children study). Ethics and dissemination The proposed study has been approved by the Health Research Authority and London-Hampstead Research Ethics Committee as application 19/LO/0181.
