Preparing all youth for the transition to adult-oriented care, adulthood itself, and a greater responsibility for their own health and health-care is an essential part of pediatric care. This process, typically described as health-care transition, can occur throughout ongoing pediatric health-care to prepare patients for transfer to an adult clinician and integration into adult care. Gaps remain in practice and in outcomes research regarding health-care transition. This review discusses recent literature, details best practices, and recommends guidance and tools to assist pediatric clinicians in providing a smooth transition process and a successful transfer to adult care for youth with and without special health-care needs.
