Dr. Helena Gleeson is a Consultant Endocrinologist at Queen Elizabeth Hospital, Birmingham. She has been at the forefront of the national work on Transition in the UK. She has worked closely with the National Clinical Director for Transition on NHS England service specifications for transition. She was a member of the NICE Guidance Development Group and NICE Quality Standards Advisory Committee for Transition both published this year. She chairs the RCP steering group for adolescents and young adults and under her leadership the group has been successful in raising the profile of transition in the RCP through having a position statement, holding a national conference, influencing training, producing guidance around acute care and influencing national bodies. Other colleges including the RCPCH have representatives on this group supporting joint collaborative working. Dr. Gleeson is a member of the Advisory Council for the Association of Young People’s Health which leads the Young People’s Health Partnership, a seven strong consortium of organisations working to raise the profile of young people’s health with the Department of Health, Public Health England and NHS England as strategic partners. Dr. Gleeson thus has the experience in the field of transition to lead the Transition Theme and to identify key collaborators and strategic partners to drive forward technology development in this area.
