Home-Based Digital Healthcare Interventions for Dementia: A Systematic Review of Patient and Family Caregiver Outcomes

Background: Home-based digital healthcare interventions are increasingly used to support people living with dementia (PLWD) and their family caregivers. However, evidence regarding their effectiveness across patient and caregiver outcomes remains heterogeneous. Methods: This systematic review followed PRISMA 2020 guidelines and was prospectively registered in PROSPERO (CRD420261302166). Six databases (PubMed, Embase, CINAHL, PsycINFO, Web of Science, and Scopus) were searched from January 2000 to October 2025. Randomized and quasi-experimental quantitative studies evaluating home-based or remotely delivered digital interventions for PLWD and/or informal caregivers were included. Risk of bias was assessed using RoB 2 and ROBINS-I. Due to heterogeneity, findings were synthesized narratively. Results: Fourteen studies met the inclusion criteria. Interventions included web-based psychoeducation, telecoaching, digital cognitive training, assistive technologies, and multicomponent programs. Caregiver outcomes demonstrated the most consistent benefits, including reduced burden and stress, improved self-efficacy, and improved sleep efficiency in technology-supported trials. For PLWD, small-to-moderate improvements were observed in global cognition and selected neuropsychiatric symptoms, particularly in interactive and personalized programs. Multicomponent interventions combining caregiver education with patient activation and professional feedback showed more durable effects. Conclusions: Home-based digital interventions appear feasible and beneficial, particularly for caregiver outcomes. Future large-scale trials with longer follow-up and standardized outcome measures are needed to confirm durability, equity, and cost-effectiveness.
