During the pandemic, a dear friend was having extreme difficulty being released from a SNF. She was convinced (and may very well have been correct) that she was going to die there in fairly short order. Because of the pandemic, the SNF drastically reduced friend and family contact with her. It took me over a week and some threatening to be able to get in to see her. To say she was frantic to get out of there would be a massive understatement.
About a week later, in complete desperation, she threw a chair through a window. That got the SNF's attention — she was released that very day.
She went to a much lower level care facility for a couple of weeks, then stayed with friends for a month or so, then went back living independently. No more help needed. She's my age and remains in excellent health, lives independently, leaves her house almost day for errands, lunches with friends, appointments, or just to go someplace interesting, and could run circles around me with her level of social and out-of-the-house activities.
p.s. In my opinion, many SNFs are at least as concerned with their bottom lines as they are with patient care. The pandemic gave all manner of facilities a level of power and control they'd never had before, and it seems they're reluctant to give that up.
