Digital Health Solutions and Its Usage by Ageing Populations in Asia: A Bibliometric Analysis and Review

Digital health has become increasingly vital for managing the needs of rapidly aging populations. This study reviews and maps research on digital health and aging in Asian countries from 2000 to 2024, identifying key opportunities, challenges, and emerging themes. Using a systematic and bibliometric approach, we screened 3,236 studies from Scopus and Web of Science and analyzed 753 eligible articles. Bibliometric techniques—including co-word, co-citation, and co-author analyses—were applied using the Bibliometrix R-package and its Biblioshiny interface to uncover the intellectual and thematic structure of the field. Our findings reveal a significant increase in research since 2018, driven by researchers based in China, Japan, South Korea, and Singapore, with a strong emphasis on telemedicine, mHealth, AI- and IoT-based systems, wearable devices, and smart home technologies. These digital health innovations enhance the quality of life, reduce fall risks, and improve care for frail older adults with chronic conditions in both clinical and community settings. However, significant gaps remain in Southeast and South Asia, and most studies are small-scale or pilot-based, which limits their generalizability. This review highlights the potential of digital health interventions to transform aging care in Asia and underscores the need for context-specific studies, multicounty collaborations, and supportive policy frameworks.
