Aim: To explore the experience and the preparedness of family carers in their caregiving role as best interest decision-makers of a relative living with advanced dementia. Background: The prevalence of dementia is a global issue. The role of being a carer of a relative living with dementia does not necessarily lessen once they are admitted to a nursing home. Best interest decision-making including end-of-life care decisions need to be made and reaching these choices can be challenging.
