Moreover, the fear of falling, even without ever actually falling, has its own serious consequences. Seniors who fear falling may restrict their activity. This, in turn, creates premature physical and functional decline, which increases their risk for falls.
A wealth of options
The first medical alert systems were introduced in the mid-1970s and were relatively simple push-button devices worn on the wrist or around the neck. Typically, the device would alert a 24-hour call center in the event of an emergency and allow wireless two-way communication. Many of these systems are still on the market, including ones from Life Alert, Medical Alert, Alert1, AMAC and ADT (makers of the AARP-affiliated ADT Companion Service®).
At the same time, innovation and sophisticated technologies have ushered in a new era for these medical alert systems. Philips Lifeline, the market leader with 750,000 customers, recently released its new AutoAlert system, which detects falls automatically, summoning help without relying on its user to push a button.
"It distinguishes between daily living activities and an actual fall with 95 percent accuracy," says Walter Van Kuijen, vice president and general manager of Home Monitoring for Philips Healthcare. Such systems are used primarily in the home or within a fairly small radius around the home. Eighty percent of falls occur in homes, notes Van Kuijen.
To appeal to younger seniors and people with active lifestyles, several companies now offer more advanced systems featuring varying combinations of push-button and automatic fall detection, emergency call center assistance, and medical monitoring. Many of these devices — which are made by such companies as MobileHelp, ActiveCare and Wellcore — are compatible with cell phones that have Bluetooth or a GPS. A system by Wellcore, for example, monitors the wearer's daily activities and delivers voice messages to users and their caregivers, including a notice if the user forgets to wear the device.
Unfortunately, that's a common problem, according to Dr. Kinosian. "It's real easy to sabotage the value of these devices," says Dr. Kinosian. "It's a great tool ... but it really needs their participation." More often than not, the owner takes a fall "while the device is hanging on the bed rail or sitting on the dining room table."
Indeed, research shows that in the majority of falls, push-button medical devices are never activated. Reasons include forgetfulness, panic, trauma or simply not wanting to alarm others. The reports also find a high rate of nonuse or resistance to using medical alert devices, even after a senior has experienced a fall.
The newer personal emergency response systems are designed to overcome most if not all of these barriers, and possibly any lingering stigma attached to their use. Many of the recent devices on the market are sleeker, lighter and less conspicuous. Some are clip-ons that resemble a cell phone or a pedometer.
"Will it work and will she wear it?" asks assistant professor Andrew Carle of George Mason University, an expert on technologies for seniors. "At the end of the day, it's all any son or daughter should ask. Will it work when your parent is unconscious a mile away? Will she wear it or will she set it aside?"
Lisbeth Schorr now uses her husband's push-button alert system. She doesn't wear it every day, however, and she didn't have it with her when she recently fell and broke her femur, away from home, where it would not have worked. For now, she keeps the device on her nightstand, and she feels safer for it.
