Dementia is a major challenge for our society. In Norway, around 40 % of persons suffering from dementia live in nursing homes (NH), and the majority experiences severe functional impairments and complex needs including associated behavioral changes. International studies indicate that NH residents with cognitive impairment and high dependency are most likely to be restrained physically. There is evidence of various adverse effects such as injuries, reduced psychological well-being or decreased mobility related to the use of physical restraint. Moreover, in addition to ethical and professional arguments, there is evidence supporting that user-involvement and shared decision-making have positive effects for both residents and staff. The aim of the present study (MEDCED) is to carry out an educational intervention in care staff to test its potential effect on use of restraint in NH residents with dementia and increase job-satisfaction in care staff.
