A portable survivorship care plan: a tool that helps educate and improve knowledge in childhood cancer survivors.

Purpose: There is a growing population of survivors of childhood cancer at risk for late effects that can affect their overall quality of life. There is evidence that they have inadequate knowledge about their diagnosis, treatment, and subsequent late effects. A randomized study was conducted to determine if a portable credit card-sized plastic card, the "Survivor Healthcare Passport," improved the survivor's knowledge of diagnosis, treatment, risks, and follow-up care.
