People who have an acute oncology admission have a 70% chance of dying in the 12 months after an admission but conversations about prognosis, death and advance care planning are not happening during admission or after discharge from hospital. This session will outline the demographics of people who have an acute oncology admission. It will explore their unmet needs and share the outputs of a series of workshops with doctors and nurses working with acutely unwell cancer patients that macmillan ran, in partnership with the UK Acute Oncology Society, which identified the barriers to conversations in these settings and how all people working in acute cancer care can improve patient experience and outcomes.
