Background There is limited evidence to guide best approaches to supportive care delivery to patients with high-grade glioma. I-CoPE (Information, Coordination, Preparation and Emotional) is a structured supportive care approach for people with newly diagnosed high-grade glioma and their family carers. Delivered by a cancer care coordinator, I-CoPE consists of (1) staged information, (2) regular screening for needs, (3) communication and coordination, and (4) family carer engagement.
