Study highlights pros and cons of AI-based apps used to benefit older adults

A new analysis from North Carolina State University highlights the realistic pros and cons of apps and other technologies that use artificial intelligence (AI) to benefit older adults, including those facing dementia and cognitive decline.

The work focuses on how these technologies can help older adults preserve their autonomy, and addresses ethical concerns that have been raised about the use of AI in so-called "carebots."

A lot of the work evaluating carebots tends to take an extremely optimistic or pessimistic stance; our goal with this paper is to avoid this sort of utopian or dystopian thinking. Instead, we look at what is actually possible, and how ethical considerations may come into play."

"Essentially, this is a reality check based on the state of the science, what may be available in the very near future, and the ethical issues that have been raised surrounding these technologies," says Allen Coin, a graduate student at NC State and first author of the paper.

Carebots run the gamut from smart apps that remind users when to take their medication to more advanced robotic devices that can retrieve prescriptions for patients or help patients get out of bed.

"The most advanced carebots allow patients to engage in limited social interactions with the technology, which gives rise to one of the most persistent ethical objections to the use of carebots," Coin says.

"Specifically, there is a concern that patients - particularly patients with dementia - are being deceived into thinking that a carebot is a person," Dubljevi? says. "In effect, the concern is that patients are being tricked into believing they're engaging with a person, rather than a device. A broader concern is that carebots will displace human workers in facilities that care for adults with dementia."

"We are in agreement that carebots should not take the place of human workers," Coin says. "However, we feel there can be substantial benefits for patients if the use of a carebot allows them to retain their autonomy for a longer period of time.

"We know that removing patients with dementia from familiar surroundings can expedite cognitive decline. If a carebot allows a patient to continue living at home for months or years, that could help patients retain a higher quality of life."

"Patients who want to live at home may not be able to afford in-home care," Dubljevi? says. "Carebots may represent a means of helping people preserve their independence."

"Ultimately, we argue that people should be able to choose how they want to be cared for," Coin says. "Yes, bad things can still happen when a person receives care from a robot. But bad things can also happen when patients are under human care - elder abuse is a huge problem.

"What's more, we're rapidly reaching a point where the number of older adults requiring care will outstrip the number of people trained to care for them. Carebots will likely be a way of helping to address that gap, and to help take on some of the tasks that currently fall on family or other unpaid caregivers."

"We can also see carebots being used to help address problems we're seeing in elder care nurses who burn out from overwork," Dubljevi? says.

The work was scheduled for presentation at the Association for the Advancement of Artificial Intelligence's Spring Symposium, and then its Fall Symposium, both of which were canceled due to COVID-19.
