Carers play a critical role in supporting people with cognitive impairment. However, they often experience substantial emotional, physical, and practical burdens. We adopted an innovative Carer-Centric Co-Creation (C4) Framework to develop a carer-centred, data-informed project to meet the needs of both people with cognitive impairment and their carers. A structured screening tool was employed to facilitate the holistic understanding and stratification of carer needs. A standardised workflow, intervention protocols, implementation procedures, and key performance indicators were developed to guide the implementation of the project.
