Objectives This study aims to identify factors among British community-based adults associated with advance care planning engagement. Factors are then compared among six domains of wishes: medical care, spiritual and religious needs, privacy and peace, dignified care, place of death and pain relief.

Methods Cross-sectional data were analysed from a stratified random sample of adults across Great Britain (England, Scotland and Wales) who were interviewed on their attitudes towards death and dying. Weighted multivariable logistic regression tested for associations with expressing any end-of-life wishes and then for each separate domain.

Results Analysis of 2042 respondents (response rate: 53.5%) revealed those less likely to have discussed their wishes were: male, younger, born in the UK, owned their residence, had no experience working in health or social care, had no chronic conditions or disabilities, had not experienced the death of a close person in the last 5 years and feel neither comfortable nor uncomfortable or uncomfortable talking about death. Additional factors among the six domains associated with having not discussed wishes include: having less and more formal education, no religious beliefs, lower household income and living with at least one other person.

Conclusions This study is the first to be conducted among a sample of community-dwelling British adults and the first of its kind to compare domains of end-of-life wishes. Our findings provide an understanding of social determinants which can inform a public health approach to end-of-life care that promotes advance care planning among compassionate communities.
