Advance care planning (ACP) as a process of discussing and recording wishes for future care and treatment is increasingly being promoted and discussed in the UK, reflecting recent changes in legislation. This study describes current ACP practice in care homes for older people drawing on data from a questionnaire survey ( n = 213) of, and interviews ( n = 15) with, care home managers. Whilst consultation about general care is taking place in the majority of homes surveyed using both formal and informal processes, the number of residents that have completed any ACP processes varies. Managers face intrinsic and extrinsic challenges related to the ascertaining of, and the implementing of wishes as they address ACP in the care home context. Until these wider contextual factors are addressed it will be difficult for staff in care homes to effectively undertake and implement ACP in care homes.
