Retrospective Examination of Peripubertal Return for Patients of Western Australia's Gender Diversity Service.

Purpose: Children far in advance of pubertal development may be deferred from further assessment for gender-affirming medical treatment until nearer puberty. It is vital that returning peripubertal patients are seen promptly to ensure time-sensitive assessment and provision of puberty suppression treatment where appropriate. This study investigates (1) how many referrals to the Child and Adolescent Health Service Gender Diversity Service at Perth Children's Hospital are deferred due to prepubertal status; and (2) how many deferred patients return peripubertally. Methods: A retrospective review of all closed referrals to the service was conducted to determine the frequency of prepubertal deferral and peripubertal re-referral. Results: Of 995 referrals received (2014 to 2020), 552 were closed. The reason for closure was determined for 548 referrals (99.3%). Prepubertal status was the second-most frequent reason for closure, and the most frequent for birth-registered males. Twenty-five percent of all deferred prepubertal patients returned peripubertally, before audit closure. A greater return frequency (55.6%) was estimated for those older than 13 years at audit closure. Conclusion: High rates of prepubertal referral indicate the importance of pediatric gender services in providing information, advice, and reassurance to concerned families. With increasing service demand, high rates of return peripubertally have implications for service planning to ensure that returning peripubertal patients are seen promptly for time-sensitive care. Frequency of peripubertal re-referral cannot, however, speak to the stability of trans identity or gender incongruence from childhood to adolescence. Clinics advising prepubertal deferral must proactively plan to ensure that sufficient clinical resources are reserved for this purpose.
