Nursing homes have been criticised for not providing a home for their residents. This article aims to provide insight into (I) the features of home and institution as experienced by residents and caregivers of a secured ward in a nursing home, and (2) how interventions implemented on the ward can contribute to a more home-like environment. For this purpose, a participatory intervention study, involving both caregivers and residents, was carried out. We collected data through qualitative research methods: observations, in-depth interviews and diaries to evaluate the interventions over time. We adopted an informed grounded theory approach, and used conceptualisations of total institutions and home as a theoretical lens. We found that the studied ward had strong characteristics of a total institution, such as batch living, block treatment and limited privacy. To increase the sense of home, interventions were formulated and implemented by the caregivers to increase the residents' autonomy, control and privacy. In this process, caregivers' perceptions and attitudes towards the provision of care shifted from task-oriented to person-centred care. We conclude that it is possible to increase the home-like character of a secured ward by introducing core values of home by means of interventions involving both caregivers and residents.
