Choosing a medical alert device for an elderly parent

Start with the person, not the device

Before comparing spec sheets, be honest about how your parent lives. Do they garden, walk to the shops, still drive? Then a device tied to the house — a wall button or a unit that only works near a base station — protects only part of their day. A mobile personal safety device with its own SIM goes wherever they go, which in South Africa means it should run on 4G, since the networks are phasing out the older 2G that many legacy alarms depend on.

Fall detection — useful, with honest limits

Falls are the classic emergency where the wearer may not be able to press anything, so automatic fall detection is worth having. But treat vendor claims carefully: no fall detection is perfect. Sensors can miss slow, slumping falls and can occasionally trigger on a dropped device. A trustworthy supplier will tell you this and quote a realistic detection rate rather than promising certainty. The rule to teach your parent: the automatic alarm is the backup — if you can press the button, press the button.

Two-way voice changes everything

A silent alert tells someone that help is needed; a voice tells them what kind. Two-way voice through the device means an operator can talk to your parent the moment the alarm raises — reassure them, find out whether it's a fall, chest pain or a false alarm, and send the right response. For an elderly person on the floor, unable to reach a phone, the difference between a beeping box and a human voice is enormous. Make two-way voice non-negotiable.

Waterproofing is not a luxury

Bathrooms — wet, hard-surfaced, and private — are exactly where you want the device worn, and exactly where a non-waterproof device gets taken off. Look for a proper ingress rating such as IP67 so the device can be worn in the shower without a second thought. A device that must be removed to wash is a device that ends up on the basin when it's needed.

Battery life is about habits, not just hours

Ask about battery life, but ask harder questions about charging: Is there a simple drop-in cradle, or a fiddly cable and tiny port? Does the device give clear low-battery warnings — ideally spoken aloud and sent to family — before it dies? The most reliable setup is a routine: the device charges in its cradle at the same time every day (breakfast works well), and someone is alerted if the battery runs low anyway. A medical alert device with a flat battery is jewellery.

Monitored response vs family-only alerts

The biggest decision is not the hardware — it is who answers. Family-only devices send alerts to your phone, which is inexpensive and fine if someone capable is always reachable. But phones are silenced in meetings, flat at night, and out of signal on holiday. A monitored service puts a 24/7 control room behind the button: trained operators who answer every alert, speak to your parent, dispatch medical assistance or armed response to a live GPS position, and still notify the family with a live tracking link. If your parent lives alone, or you are frequently unavailable, monitoring is usually the difference that justifies the subscription.

A quick comparison checklist

• Works away from home, on 4G — not a 2G device facing network switch-off
• Automatic fall detection, with honestly stated limits
• Two-way voice through the device
• IP67 waterproof so it stays on in the shower
• Simple charging cradle plus low-battery alerts to family
• A 24/7 monitored response option, with live location for responders
• Comfortable to wear all day — pendant or wristband, their choice

Finally, involve your parent in the choice. The best device is the one they will actually wear — every day, in the shower, into the garden — without being reminded.
