Smartwatch technology improves alert system for senior living facilities

Elderly individuals have long relied on medical alert bracelets to notify others in case of an emergeny. Now, this method is getting an overhaul thanks to researchers at Binghamton (N.Y.) University.

Researchers have developed a smartwatch app that can alert certified nursing assistants (CNAs) more quickly and effectively when a senior in a nursing falls or is in trouble. Most nursing homes rely primarily on acall light system, when a senior pushes a distress button and sends an alert. But when a caregiver is out of reach, these alerts can go undetected.

"The problem associated with not responding in time is that residents tend to stand up or go to the bathroom by themselves. If they're not strong enough, they can't support the weight. And if they have to wait, they will just get up and go. And that leads to falls," said Binghamton Assistant Professor Huiyang Li. "We wanted to design a better system that improves notification and also, potentially, communication in nursing homes. The improvement of notification will potentially help staff to do a better job and, eventually, improve patient safety. Whenever residents need help, they have a way to call for help, and messages will be delivered to staff in an effective way."

The smartwatch can alert CNAs by integrating all types of notifications systems in nursing homes including call lights, chair alerts, bed alarms, wander guards and call-for-help functions. The app provides each CNA a display of all patients. When the alert is signaled, a message comes up on the watch showing who the resident is, the room number and type of alert.

"With our system, we provide an informative and customized message for different alarms. The message contains the resident's name, the type of alarm, the room number and the CNA who is responsible. The smartwatch will be on the CNA's wrist, so it's accessible all the time. They can see the message, hear the alarm, and feel the vibration, whether they are working down the hallway or inside the rooms," said Li. "The alert message is more informative than the existing system and, at the same time, it will help nurses to prioritize. We will mark or highlight alarms from residents who are actually assigned to whoever is using the app.”
