Serious illness care Programme UK: assessing the 'face validity', applicability and relevance of the serious illness conversation guide for use within the UK health care setting.

Use of the guide has the potential to benefit patients, facilitating a 'person-centred' approach to these important conversations, and providing a framework to promote shared decision making and care planning. Further research is ongoing, to understand the impact of these conversations on patients, families and clinicians and on concordance of care delivery with expressed patient wishes.
