The Long-Term Use of Communication Robots by Users of Visiting Healthcare Services: Development of an Integrated Vital Signs Measurement System.

Purpose This study explores the use of communication robots (CRs) to sustain self-care behaviors among older adults, addressing motivational challenges. Method We used the CR PALRO® (FUJISOFT, Kanagawa, Japan) and developed a system to wirelessly transmit vital signs data (temperature, blood pressure, pulse oximetry) to cloud storage. PALRO reviewed the data and provided feedback to the user. One participant, a woman in her 90s living alone and using a nursing service, was recruited with ethical approval from the University of Tokyo's Ethical Review Board. Results Before using the CR, the participant had stopped measuring her temperature and blood pressure. After implementation, she measured her vital signs for 334 days, storing the data in the cloud. The system prompted measurements without reminders 248 times in 334 days (74.3%) and gave feedback when measurements were missed. Conclusion/implications The CR system is feasible for visiting care service users, promoting self-care and early abnormality detection. Future improvements could enhance self-care for independent older adults.
