Research Question : Can Robots Effectively Reduce Caregiver Shortages in Elderly Care?

Many countries are facing serious caregiver shortages as their populations continue to age. In Japan, the demand for long-term care workers has increased rapidly, while the number of available caregivers has not kept pace. As a result, robots and artificial intelligence (AI) are being introduced into nursing homes and healthcare facilities to support both caregivers and older adults. However, an important question remains: can robots effectively solve caregiver shortages?

One advantage of care robots is that they can assist with physically demanding and repetitive tasks. For example, lifting robots can help caregivers transfer patients safely, while monitoring systems can detect falls or track changes in an older person’s health. Robots can also remind older adults to take medication or guide them through simple daily activities. According to Broadbent et al. (2009), healthcare robots have the potential to reduce caregivers’ workload and improve the efficiency of care, especially as the number of older adults continues to grow.

In addition to physical assistance, some robots are designed to provide emotional support. Social robots, such as Japan’s PARO, have been used in nursing homes to reduce loneliness and encourage communication among older adults. Research by Pu et al. (2019) found that social robots can improve mood, increase social interaction, and reduce feelings of loneliness in some older adults. Although they cannot replace human relationships, they may improve quality of life when used alongside human care.

Despite these benefits, robots also have important limitations. They cannot provide empathy, emotional understanding, or complex decision-making in the same way that human caregivers can. Many older adults also prefer receiving care from people rather than machines, especially when personal or emotional support is needed. In addition, the high cost of purchasing and maintaining robotic technology may make it difficult for smaller care facilities to adopt these systems.

Overall, robots can help reduce caregiver shortages by supporting routine tasks and improving efficiency, but they are unlikely to replace human caregivers completely. Instead, the most effective approach is to use robots as tools that assist care workers, allowing them to spend more time providing emotional support and personalized care. As technology continues to develop, combining AI with human expertise may become an important solution for elderly care in ultra-aging societies.
