Involvement, topics, and roles of nurses in shared decision-making with patients with dementia in acute hospitals: An integrative review.

Only nine studies were included, and eight were qualitative, so the review describes processes rather than measuring patient outcomes. The included studies had different aims, populations and settings, so the findings are heterogeneous. None of the included studies explicitly focused on nurses' roles in shared decision-making with dementia in acute hospitals. The review could not show how dementia or cognition affects patients' ability to participate in decisions. Only one randomized controlled trial was found, and the authors note possible publication bias. The analysis used Groen's model, which was developed for dementia networks, not acute hospitals.

Do not read this review as proof that involving nurses improves shared decision-making or patient outcomes. It maps roles and topics from mostly qualitative studies, and the authors say there is too little direct evidence to judge benefit.
