Abstract Background The Assisted Decision Making (Capacity) Act 2015 was fully implemented in April 2023. This brought changes to how health and social care staff work with patients who may lack decision making capacity for certain decisions. The most significant group impacted by these changes in the acute hospital context is Older People with cognitive impairment. Staff working with these patients have been navigating the complex balance between embracing the guiding principles of the Act, testing the practical requirements of the Act on behalf of patients who require formal decision supports, all in the context of continued demand on unscheduled care. Methods The newly developed role of Principal Social Worker for Assisted Decision Making and Adult Safeguarding has enabled regular access to frontline staff working across 11 hospitals in a large hospital group. Both formal and informal feedback was gathered from a cross section of staff via focussed discussion at local implementation meetings and via individual qualitative interviews with key stakeholders from a broad range of professions. Results Staff were generally very positive about the introduction of the Act and its rights-based approach to providing health and social care. Themes which emerged from the interviews included the need for further education and training, continued forums for case discussion and review, clarity re roles and responsibilities and improved pathways for patients requiring support. Conclusion The enactment of the Assisted Decision-Making Act did not, as many feared, bring the healthcare system to a standstill. However, its impact on resources and time should not be underestimated. Increased investment in staffing, training and supports are needed to ensure continued integration of the Act in the acute hospital setting.
