Care-home residents with dementia can experience behavioural and psychological symptoms such as aggression, agitation, anxiety, wandering, calling out and sexual disinhibition. Care-home staff have a duty to keep residents safe. However, residents with dementia can pose particular challenges in this area. In this paper, we draw on a study which explored how care-home staff manage dementia-related behaviours. In-depth ethnographic case studies at four separate care homes were conducted in England. These involved interviews with 40 care-home staff and 384 hours of participant observation. Our analysis showed that some residents with dementia experience behaviours which can either create risks for, or negatively impact on, themselves and/or other residents or staff members. It emerged that the consequences of the behaviours, rather than the behaviours themselves, created difficulties for staff. To cope with the risk and impact of behaviours, staff employed multiple strategies such as surveillance, resident placement, restrictions and forced care. Using the data, we explore how actions taken by staff to manage the risk and impact of behaviours in these communal settings relate to residents’ human rights. Our findings have particular relevance for care-home staff who need support and guidance in this area, for service development worldwide and for the global ageing population whose valued human rights may become under threat, if they require long-term care.
