@mimi0000 As @JaneCares says - the back up plan will vary according to your situation! I cared for both of my parents in my home, with the help of their Long-term care insurance (to help with paid caregivers) and the VA (Dad was a Veteran and he got home health aides to help with bathing and dressing, medical supplies, medications and eventually home-based primary care rom the VA). It can be done! I used a lot of mobile health services also - doctors and lab tests, x-rays, ultrasounds etc. at home - when it got really hard for my parents to go out.
I think for most people a backup plan instead of nursing home care means home care. But for some it's a smaller "group home" or "residential care facility" where there are fewer people (usually up to 10 - licensing depends on the state).
AARP has lots of good information on home-based caregiving on the website!
Take care,
