Health Intel: The Conversation Project is based around a “Starter Kit” which gives a simple framework to think through, and then talk through, your wishes for future care. It also includes stories that help get the process started.
A quick internet search shows it’s quite hard to find similar resources in the UK without going through hospice and cancer care pages, so have a think about how this toolkit, or a more local project, might be able to help people have “the conversation.”
