This systematic review presents an overview of the existing dementia care models in various ambulatory care settings under three categories (i.e., home- and community-based care models, partnership between health systems and community-based resources, and consultation models) and their impact on hospitalization among Persons Living with Dementia (PLWD). PRISMA guidelines were applied, and our search resulted in a total of 13 studies focusing on 11 care models. Seven studies reported that utilization of dementia care models was associated with a modest reduction in hospitalization among community-residing PLWD. Only two studies reported statistically significant results. Dementia care models that were utilized in specialty ambulatory care settings such as memory care showed more promising results than traditional primary care. To develop a better understanding of how dementia care models can be improved, future studies should explore how confounders (e.g., stage of dementia) influence hospitalization.
