The available evidence suggests a likely prevalence high enough to make it worthwhile screening hospital inpatients for depression and initiating treatment where appropriate. Further, higher quality, research is needed to clarify the prevalence of depression in specific settings and to further explore the reasons for the observed heterogeneity in estimates.

Aims and methodTo describe the pattern of referrals and characteristics of people aged over 18 seeking gender reassignment in Oxfordshire over a 6-year period (2011–2016).ResultsA total of 153 individuals attended for assessment (of 162 referred); 97 (63.4%) were natal males and 56 (36.6%) were natal females. Mean age at referral was markedly different between the two groups, with females being younger. The number of referral significantly increased over the time period, by an average of 18% per year (95% CI 1.08–1.30). Eighty-seven patients sought transition from male to female, and 46 from female to male, while a smaller group (n = 13) had non-binary presentations. Twelve patients (7.8%) had autism spectrum disorder.Clinical implicationsThere are various possible reasons for the increased demand for services for people with gender dysphoria, which we discuss here. When planning services in the UK, both the increase in overall referral rates and the apparent earlier age at referral should be taken into account.Declaration of interestNone.

Screening has the potential to offer a solution to the well-documented problem of missed depression and other psychiatric diagnoses, thereby improving patient care if closely linked to treatment provision.
