Transitioning survivorship care from oncologists to primary care physicians (PCPs) is a reasonable alternative to oncologist-led care. This study assessed oncologists’ attitudes and beliefs regarding sharing/transitioning survivorship care. A prospective survey of oncologists within a regional cancer program assessing self-reported barriers and facilitators to sharing/transitioning survivorship care was disseminated. In total, 63% (n = 39) of surveyed oncologists responded. Patient preference (89%) and anxiety (84%) are key to transition of care decisions; reduced remuneration (95%) and fewer longitudinal relationships (63%) do not contribute. Oncologists agreed that more patients could be shared/transitioned. Barriers include treatment-related toxicities (82% agree), tumor-specific factors (60–90% agree) and perception of PCP willingness to participate in survivorship care (47% agree). Oncologists appear willing to share/transition more survivors to PCPs, though barriers exist that warrant further study. Understanding these issues is critical to developing policies supporting comprehensive survivorship care models that address both cancer and non-cancer health needs. The demonstrated feasibility of this project warrants a larger-scale survey of oncologists with respect to the transition of survivorship care to PCPs, to further inform effective interventions to support high-quality survivorship care.
