This study develops a toolkit to enhance Shared Decision Making (SDM) in long-term care (LTC) for older people with dementia. Recognizing their right to participate in care decisions, the study adopts a co-production approach for toolkit development, including needs assessment, scoping review, guideline creation, and a pilot study. The toolkit, targeting LTC providers and users (people with dementia and their caregivers), features an image-based menu for easier understanding and decision-making in care choices and educational materials for users. Designed for direct clinical use, the toolkit aims to improve healthcare equity in LTC settings, offering a practical solution for policymakers to incorporate SDM in long-term care practice.
