The long-term use of transfer support robots in nursing facilities is an important option for improving the efficiency of care work. The "Resyone" transfer support robot is a combination of an electric care bed and a wheelchair, and the wheelchair half of the bed can be detached at the touch of a button. The purpose of this study was to investigate how the long-term use of Resyone would improve the performance of transfer assists, such as reducing the need for multiple caregivers. One Resyone was installed in a nursing facility in Japan and 17 caregivers used it for more than 11 months. The time and number of caregivers required for each transfer assist were surveyed for three 1-week periods: 1 week before (Phase 1) and at 3 weeks (Phase 2) and 11 months (Phase 3) after the introduction of Resyone. In Phase 1, approximately 60% of all transfer assists were performed by two caregivers, but in Phase 2, this was reduced to approximately 20%, and finally, in Phase 3, all transfer assists were performed by a single caregiver. These results suggested that the long-term use of Resyone was associated with improved work efficiency in transfer assistance in a nursing facility.
