Objectives There is increased global focus on advance care planning (ACP) with attention from policymakers, more education programmes, laws and public awareness campaigns.

Methods We provide a summary of the evidence about what ACP is, and how it should be conducted. We also address its barriers and facilitators and discuss current and future models of ACP, including a wider look at how to best integrate those who have diminished decisional capacity.

Results Different models are analysed, including new work in Wales (future care planning which includes best interest decision-making for those without decisional capacity), Asia and in people with dementia.

Conclusions ACP practices are evolving. While ACP is a joint responsibility of patients, relatives and healthcare professionals, more clarity on how to apply best ACP practices to include people with diminished capacity will further improve patient-centred care.
