A team conducted semistructured interviews and developed case reports about financial toxicity (FT) and healthcare transitions (HCTs) with two adolescent and young adult (AYA) cancer survivors. These reports found poor HCTs from pediatric specialty care to adult primary care. Nurses can address FT and facilitate smooth HCTs by screening AYA survivors and caregivers for financial stressors, engaging in cost-of-care conversations and interprofessional care coordination, and supporting access to navigation services.
