What Do We Need to Know About Transition/Transfer Programs and What Sort of Research Will Answer the Questions?

Despite an increasing literature, there are many unanswered questions about transition to adult care for youth with chronic disorders. This paper questions the definition and components of optimal transition programs, their effectiveness and costs. Few transition programs have been comprehensively evaluated and effectiveness studies are usually based on a historical control group. Transition clinics for neurological disorders are described but not evaluated. Studies in diabetes, renal transplant, and rheumatologic disorders provide the best available evidence, albeit limited, of the value of transition clinics/programs. A few studies have addressed the cost of transition clinics and suggest that the incremental costs of the clinic are recouped by reduced medical costs in adult care. There is room for a great deal more research about transition.
