Background: Shared decision-making (SDM) is a means of allowing people with dementia to take part in making choices, be autonomous and participate in social activities. Involving them in SDM is an important way of promoting social health. However, including families and dementia residents in decision-making can be challenging for care staff working in nursing homes. The objective of this study was to identify barriers and facilitators regarding the implementation of an SDM framework for care planning in two nursing homes, one in Italy and one in the Netherlands. Methods: Focus group interviews were conducted with healthcare professionals who, after being trained, applied the SDM framework. Content analysis was used to analyze the data. Results:Six months after the feasibility trial, focus group interviews with healthcare professionals (n= 10 in Italy;n= 9 in the Netherlands) were held. We found 6 themes and 15 categories. Within these themes, facilitators and barriers were identified. The categories of team collaboration, communication skills and nursing home policy were found to be facilitators to the implementation process, whereas regulations, lack of funding and of involvement of family caregivers were the main barriers. Family attitudes towards SDM could be both. The main difference between countries concerned the residents’ cognitive status that influenced their degree of involvement. Conclusion: Communication skills training for professionals, training of family caregivers, and involvement of the management in the implementation process seem to be crucial factors in successfully implementing SDM in nursing homes, and increasing the involvement of families and dementia residents in decision-making.
