Background: A transition of care (TOC) process from pediatric to adult medicine ensures that adolescents receive ongoing care into young adulthood, a time of high risk for preventable morbidity and mortality. Methods: We explored patient, caregiver, and physician perspectives on ways to improve TOC communication with healthy adolescents. Two researchers conducted key informant interviews with healthy 12- to 18-year-old adolescents, their caregivers, and primary care physicians working in pediatric, internal, and family medicine.
