Have just heard about this new position paper from Royal College of General Practitioners:
"There is an urgent need to increase the capacity of gender identity specialists and clinics and expand the understanding of gender variance issues across the entire health system, including more definitive knowledge about the causes of rapidly increasing referrals and the outcomes of interventions or 'wait and see' policies. The gaps in education, guidance and training for GPs around treating gender dysphoria for both adults and children, and managing broader trans health issues, also needs to be urgently addressed."

"This paper provides an overview of the key issues facing gender-questioning and transgender patients, general practiceand the broader health system. It establishes the RCGP’s position on the role of aGP in providing care to patients experiencing gender dysphoria, the policy principles underpinning this position and recommendations for ensuring these patients receive equal access to the highest standard of care."

Have only skim read, and it has some stats in it, but they also seem to be relying on the Government Survey of LGBT+ Health Needs.
