Transition from paediatric to adult care for chronic diseases may cause insecurity and unpreparedness for new relationships and surroundings.

Context Transition of young people from child to adult healthcare services has been the subject of much research. Despite the available evidence, young people continue to experience difficulties when transferring to adult care. Much of the previous research has focused on children and young people with specific conditions and has used small sample sizes, which limit the ability to generalise results. Two previous systematic reviews on transition have been undertaken ; however, there is still no consensus about the most appropriate age or method for transition, or how transition is best implemented.
