These materials have been created to help support health and social care professionals working with individuals whose decision-making capacity is limited, fluctuating, absent or compromised. Demographic changes mean there are increasing numbers of people living with conditions which may impact on their decision-making capacity, and as such it is vital that professionals are confident in their understanding use of the Mental Capacity Act 2005. This tool brings together information from a range of professionals working in the field of mental capacity to provide a comprehensive guide to practice. It is part of a wider research project funded by the Burdett Trust for Nurses.
