Very stringent, but remember they are only inspected at most once a year unless someone calls with a problem. The other 364 days they are not inspected, which means that a loved one should visit as often as possible. For example, my 90 year old mother is in a skilled nursing home right now and we visit every day. She's moving to assisted living next week and we're going to have someone stop by every day. There are several levels of long term care facilities.
Skilled nursing is the most medically intensive.
It is for people who have major medical problems and can either be rehabilitated or will need major medical supervision. Intermediate care is a step below that. It's for people who have less than demanding medical needs but need full assistance in the tasks of daily living. Assisted living facilities have pretty much replaced intermediate care facilities, although they are legally not intermediate care. That last distinction is very important because Medicaid will pay for intermediate care, but not assisted living.
