A medical alert button and a location device solve different problems. One may connect a person to help; another may help an authorised contact locate a device. Neither replaces an appropriate support plan, and a product’s label does not establish that it suits a person living with dementia.

Start with the job to be done

Write the situation you want help with. Is the concern getting assistance after a fall, finding a person who may become lost, or making everyday phone calls easier? Ask the care team which approach fits the person’s abilities and risks before comparing products.

Then ask whether the person can and will use it. A button must be worn or reachable. A rechargeable device must be charged. A location service may be ineffective if it is left on a table. Plan who checks these tasks without assuming the person will remember a new routine.

Ask about the response chain

  • Who receives an alert, and are they available at those times?
  • What happens if the first contact does not answer?
  • Does the service contact emergency responders, and under what conditions?
  • What cellular or internet connection is required?
  • What happens during a power outage or loss of coverage?
  • How should the system be tested without making a false emergency call?

Check limitations of automatic detection with the manufacturer. Do not assume every fall, emergency or movement will be detected.

Discuss location sharing with the person and obtain appropriate advice about decision-making if needed. Confirm who can access location history, how accounts are protected, what information is retained and how access can be removed. A device should not become a reason to share someone’s movements with more people than necessary.

Compare the full cost

Record equipment price, activation, subscriptions, replacement charges and cancellation terms. Ask about trial periods and returns. Keep dated product specifications, because features and coverage can change. The provider comparison worksheet can also be used to record answers from device suppliers.

This is a purchasing framework, not a tested-product ranking. We have not independently tested devices described by suppliers, and advertisements are not endorsements. If someone is missing and may be at risk, contact local emergency services promptly rather than relying only on an app.
