This article reviews the literature on the inclusion of the perspective of people with dementia when evaluating quality of care. The few identified relevant studies suggest that there is consensus that people with mild to moderate dementia are able to talk about their experiences with care with clarity and insight. A minimum level of orientation to place, attention and language skills in the person with dementia are important for a successful subjective evaluation. On the basis of the relevant literature, we additionally formulated practical guidelines useful when one aims to collect information with interviewing, self-administered questionnaires, or focus groups from people with dementia to assess quality of care. In people with mild to moderate dementia, assessment of quality of care can best be done by individual interviewing and focus groups. Further research is needed to ascertain what people with dementia find important in relation to quality of care.
