Patient/family education is an important component of nursing practice and is essential to the care of children newly diagnosed with cancer. Practices regarding patient/family education in Children’s Oncology Group (COG) treatment centers have not been well described. We used an Internet-based survey to determine current patient/family educational practices at COG institutions; participation rate was 90.5% (201/222). Patient/family education was delivered primarily by an individual (rather than a team) at 43% of institutions. Advanced practice nurses had primary responsibility for providing education at 32% of institutions. "Fever" was the most frequently reported topic considered mandatory for inclusion in education for newly diagnosed patients. More than half of institutions reported using checklists and/or end-of-shift reports to facilitate health care team communication regarding patient/family education, and 77% reported using the "teach-back" method of assessing readiness for discharge. Thirty-seven percent of institutions reported delays in hospital discharge secondary to the need for additional teaching. An understanding of current practices related to patient/family education is the first step in establishing effective interventions to improve and standardize educational practices in pediatric oncology.
