It’s probably quite pricy now. Give it 5 years and it’ll be a cheapo addon that is getting stuffed into every pill out there. Certainly every brand-name pill. Same thing with smartphones – and I’ll bet it’s only a matter of time before some variant of the app makes an appearance as part of MedMinder or LifeLine.
So, some digging later, the patch is huge. Proteus aren’t exactly giving much detail on how the system works, but I’m guessing the patch is serving as an external power source using induction. The sensor itself would probably be activated after coming in contact with stomach acids – which could, in theory, also serve as a way to power it. The sensor would be extremely low-power and low-range, hence the need for a patch in the first place.
I do have to wonder about whether the patch is waterproof and how often it needs to be removed. If it involves a daily routine of attaching and detaching, then I agree, it probably isn’t well-suited for elderly people afflicted by some degree of dementia. On the other hand if the patch can be worn for a week or a month at a time, and can be replaced or recharged during a regular visit by a caregiver, things become more feasible.
As far as the complexity of the communication chain, I think you’re sticking too closely to the proposed script. Absolutely, the message should go to the person best able to make sure the patient gets their medication as close to on schedule as possible. That may be a care provider, a family member, or just a loud and annoying reminder alarm on the smartphone. Just because the currently proposed application involves sending a message to the doctor doesn’t mean that is, or always will be, the only option. We’re just a software update away from that concern being addressed.
As to the patient getting multiple medications confused, you’re right that this technology isn’t going to make things magically problem-free for them – but there will be a subset for whom it will make a difference. Hell, some mornings I would love to have some verifiable record of whether I’d already taken my medications! Screw reporting to my doctor; I want to have an app that lets me know. And no, I’m neither particularly old nor afflicted with memory problems.
Gastric acid is 1.5-3.5 pH. Straight lemon juice is around 2.0. More significantly, orange juice is around 3.0, so it overlaps with gastric acid. I’ll bet this medication will come with a warning to not mix with orange juice or other acidic drinks. I know from first-hand experience that some perfectly ordinary medications on the market already come with that warning.
As far as deliberate attack, yes, this can probably be defeated with enough effort (depending on how exactly the sensor is being activated). But as the coverage says, this isn’t going to be applicable to all situations. The point of the tech as I read it is to simplify monitoring, not completely supplant existing check-ups. If you’re a schizophrenia sufferer who decides to stick it to The Man by fooling the sensor technology, your psychiatrist will more than likely be able to tell you aren’t taking your meds.
