Artificial intelligence and devices connected to the internet are being introduced to nursing care in Japan, where there is a chronic shortage of caregivers due to its graying society and the way the coronavirus pandemic has restricted face-to-face contact.
Sensors are monitoring the lifestyle habits of the elderly while AI-initiated phone calls are checking on seniors daily, allowing caregivers to look after them remotely.
“You went to the bathroom many times yesterday,” a care manager says over the phone to a man as he checks data on his recent routine.
The man’s home is equipped with sensors installed in the bathroom, bedroom and refrigerator, as well as attached to doors, providing the care manager with data on how frequently he uses the bathroom, how long he sleeps and whether he has eaten.
The sensors do not emit light or sound so as not to bother the resident.
The city of Miyakonojo, Miyazaki Prefecture, has tried using data collected by the devices to create care plans for people in its “digital care management” project and assessed its effectiveness last year.
Working with major electronics maker Panasonic Corp. and a group of local care managers, the city analyzed the project results for three months from October and found that the lifestyle habits of all four people who took part in the trial improved.
Shinichi Omine, deputy head of the group, said he felt “data can turn users’ worries into a sense of security.”
A wearable device that indicates when it’s time to urinate is helping caregivers and care recipients alike.
Triple W Japan Inc., a Tokyo-based internet technology firm, developed the device DFree featuring a sensor that can measure bladder size using ultrasound and notify caregivers through the internet when it reaches a certain size and it’s time for their client to go to the bathroom.
“Cleaning up after a toilet mishap is a heavy burden on care workers both in terms of time and physical effort,” said Masaya Matsumura, 34, of Social Welfare Corporation Zenkoukai in Tokyo, which runs a number of nursing homes.
He added the device “helps maintain the dignity of the elderly” by preventing them from wetting themselves.
Nara Prefecture is starting a trial of an AI phone call service to check on the health of senior citizens daily.
In the trial also involving NTT Docomo Inc., people are asked whether they are in pain. If, for example, they reply that their knees hurt, the service will ask how long they have had the symptoms and whether they have gone to see a doctor.
If the people say they are not feeling well or if they do not respond to calls, a family member will be notified.
“If we accumulate data, we will be able to quickly spot a sudden change in someone’s health condition or the development of dementia,” said a Nara Prefectural Government official in charge of the project.
The number of care workers stood at about 1.95 million in fiscal 2017, and the industry’s jobs-to-applicants ratio remains more than twice as much as the average for all industries, reflecting a chronic labor shortage in the sector.
