Smart Home Technologies for Ageing in Place: A Systematic Review of Health Outcomes, Independence, Healthcare Utilisation, and Implementation Considerations

Objectives Smart home technologies are increasingly being developed to support ageing in place, yet evidence of their impact remains unclear. This study sought to synthesise the existing evidence on the role of smart home technologies in enabling adults aged 65 years and older to live safely at home. Methods A systematic review was conducted in accordance with PRISMA guidelines. Seven databases were searched for studies published between 2020 and 2025. Quantitative, qualitative, and mixed-methods studies evaluating smart home technologies were included. Methodological quality was assessed using JBI and MMAT tools, and data were synthesised thematically. Results Thirty studies from 10 countries were included. Smart home technologies supported physiological monitoring, safety, functional and emergency detection, social interaction and cognitive support. Reported benefits in some studies included reduced healthcare utilisation, improved quality of life and independence, enhanced chronic disease management, and positive experiences for users and carers. However, findings were heterogeneous across technologies, populations, and outcome measures. Key barriers included privacy, cost, technical reliability, and digital literacy. Conclusion Smart home technologies show potential to support ageing in place by enhancing safety, independence, and chronic disease management, while possibly reducing healthcare utilisation and improving quality of life. However, the evidence base remains heterogeneous, and more robust longitudinal studies, standardised outcome measures, and comprehensive cost-effectiveness evaluations are needed to inform implementation, equity, and policy development.
