I would agree with you as long as the devices you're referring to are completely automated and rely 0% on the person to do something. My grandmother didn't remember things so well as she got older, so without someone to help her to remember to take her medicine (or that she had indeed taken it) it would have had real implications for her health. As it happened, she had my mother and later my uncle to take the place of the nurse. In my limited experience, the key to seniors is to avoid having to rely on their memory. As for avoiding complications, I agree with you. The best action is to avoid the disease, and then to avoid the effects of the disease. As mentioned in the article, sending a person in a car to visit someone is obviously more expensive than a phone call. But the nurse's visit can help to avoid a problem which requires a far more expensive visit to the hospital. That is where the cost savings come into play.
