The prevalence of dementia will continue to increase with the ageing of the population. Many people living with dementia will reach a stage where surrogate decision-makers-mostly family carers-will need to make a range of decisions on their behalf. The aim of this study was to learn from surrogate decision-makers how they can be most effectively supported in this role. The study employed a qualitative design using semi-structured face-to-face or telephone interviews with a purposive sample of 34 surrogate decision-makers of people living with dementia.
