Some might remember a couple of months back my post about the MIL having a mini stroke which landed her in the hospital for two weeks. Before the strokes, she was not on top of her blood sugars. In fact we had been trying to get her in to see her doc about her multiple falls and a heating pad burn on her lower back which she had hidden from everyone. She had also been resisting the idea of home care. Turns out her blood chemistry was way out of wack. Very low in magnesium.
My wife is amazing. She had been looking into home care before the strokes. When we heard from the hospital the MIL was being released that day, my wife managed to pull together all the threads and have a home care worker in the house when Mom got home.
The good news: The driving issue had been settled the year before, as nerve damage was keeping her from pressing the clutch (Yes, my MIL was rocking a manual shift when she turned 90!)
Also, the strokes made her realize if she wanted to stay in her own home as long as possible, she would have to accept this level of home care. She is on the lists for three care homes within 50 km, but because of Care Worker shortages (partially related to Covid) there have been no new admissions. She has accepted she will have to go when there is room and leave the house which has been her home for 75 years.
Personally, I would advise you to disable your Dad's car. It is drastic and possible illegal. Who has power of attorney? Is there one? How about a living will? My MIL when she was her practical, rational self a few years back told her Doc she wanted a DNR order. There is a copy on her fridge. Apparently, that's where the EMTs look for one.
We were lucky. I can see my in-law's house from our yard. I can't imagine dealing with the distance too.
