Introduction Dementia imposes significant care and financial burdens on families and countries globally. While high-quality home-based care is crucial, the current supply chain of care—relying on family caregivers and community healthcare workers—remains fragmented and lacks effective integration. Furthermore, although artificial intelligence (AI) holds promise, existing applications predominantly focus on diagnosis or monitoring rather than holistic care delivery and quality of life (QoL). This study aims to evaluate the effectiveness of the community home-based dual-supplier cooperation (CHDSC) care model in older people with dementia. Methods and analysis A 1-year, assessor-blinded, parallel-group, superiority randomised controlled trial with 1:1 allocation will be conducted. A total of 200 pairs (community-dwelling people with dementia aged ≥65 years and their primary family caregivers) will be recruited from four community health centres in Guangzhou, China, and randomly assigned to either the CHDSC care model intervention or usual care. The intervention comprises monthly home visits following a structured six-step cycle (problem assessment, personalised recommendation generation, case seminar, training, task execution with progressive handover and reassessment), delivered collaboratively by community healthcare workers and family caregivers and guided by an intelligent decision-assistance system. The primary outcome is the QoL of patients assessed using the Quality of Life in Alzheimer’s Disease scale. Secondary outcomes include caregiver burden, quality of home-based care, behavioural and psychological symptoms, cognitive function, ability to perform activities of daily living, adverse event rate and unplanned readmission rate. A comprehensive process evaluation embedded in the randomised controlled trial will be taken. Ethics and dissemination Ethics approval was obtained from the Institutional Review Board of Jinan University. Written informed consent will be obtained from all participants. The study findings will be disseminated through publication in a peer-reviewed journal and presented at conferences.
