There is a global need to transform cancer follow-up care to address the needs of cancer survivors while efficiently using the health care system to limit the effects of provider shortages, gaps in provider knowledge, and already overburdened clinics; improve the mental health of clinicians; and limit costs to health care systems and patients. England, Northern Ireland, and Australia are implementing an approach that triages patients to personalized follow-up care pathways depending on the types and levels of resources needed for patients' long-term care that has been shown to meet patients' needs, more efficiently use the health care system, and reduce costs. This article discusses lessons learned from these implementation efforts, identifying the necessary components of these care models and barriers and facilitators to implementation of this care. Specifically, the United States and other countries looking to transform follow-up care should consider how to develop six key principles of this care: algorithms to triage patients to pathways; methods to assess patient issues to guide care; remote monitoring systems; methods to support patients in self-management; ways to coordinate care and information exchange between oncology, primary care, specialists, and patients; and methods to engage all stakeholders and secure their ongoing buy-in. Next steps to advance this work in the United States are discussed.
