Transferring adolescent patients from pediatric to adult renal units can be difficult for all concerned. There has been little agreement or discussion on the factors involved in the timing of the transition. Communication and choice are key words when dealing with young people. The process of transition can be improved by discussion between the patient and team members on the likely timing of transition and the choice of an adult unit offering the same treatment modalities, for example, automated peritoneal dialysis. Information about the adult unit should be obtained, and liaison visits by patient, family members, and possibly accompanying staff are considered helpful. Transition should be a positive event, and each adolescent will require an individualized plan devised in discussion with team members.
