[Supporting the adolescents with chronic condition during transition: Role of the transition units]

The transition of care between pediatric and adult care is a key-period for adolescents with chronic disease, because of the high risk of follow-up loss and of short-term and long-term poorer health. To support transition, platforms of transition have been created in France since several years, implemented in pediatric or adult care structures. Their common objective is to provide a physical reception of adolescents and their parents to share about transition issues, and to inform them about resources to enhance the adolescent's global health. They tend to work closely with the referent health care providers and the patients' associations. A large heterogeneity of functioning and health care supply is still observed in these recent structures. Supporting these structures and reinforcing the partnerships between pediatric and adults care remain a challenge.
