This study uses a hybrid effectiveness-implementation design integrating a cluster randomized controlled trial and implementation evaluation. The trial will assess the effectiveness of a dementia management competency training program for primary health care providers at both the individual and organizational levels. At the individual level, the study will evaluate the effects of the training on dementia knowledge, attitudes, practice competency, and dementia management-related clinical behaviors. At the organizational level, the study will examine reach, adoption, implementation quality, and maintenance of the training program in real-world primary healthcare settings.The study will be conducted in community health service centers and township health centers in Nanping, Fujian Province, China. Primary healthcare institutions will serve as clusters. Approximately 16 institutions will be recruited and randomized to the intervention or control group at a 1:1 ratio, with approximately 20 primary health care providers recruited from each institution.The intervention group will receive a 12-week structured blended training program named "Hand in Hand Along the Memory Path". During weeks 1-4, participants will complete seven online learning modules, with a total learning duration of approximately 3 hours. At the end of week 4, participants will attend an in-person skills workshop of approximately 2 hours, focusing on standardized use of cognitive screening and assessment tools. During weeks 5-12, participants will take part in online case-based supervision every two weeks and complete practice tasks related to cognitive screening and dementia management.The control group will receive self-directed online learning materials, including the same knowledge module videos and text-based materials. However, the control group will not receive structured learning tasks, case analysis, knowledge tests, demonstration videos, forum-based support, learning reminders, expert support, toolkits, in-person workshops, or case-based supervision.Quantitative data will be collected at baseline, immediately after the intervention, and 3 months after the intervention. Semi-structured interviews will be conducted 3 months after the intervention to explore participants' experiences, implementation barriers and facilitators, and factors affecting maintenance. Quantitative and qualitative findings will be integrated according to the RE-AIM framework.
