Do you trust nursing homes?

With all the bad publicity surrounding nursing homes, it makes me wonder if its safe to keep my mother in one. so far, she has received the best of care. also, should nursing homes be on just one floor level, instead of a high-rise type building? my mother’s nursing home is on one level. for safety, in case of a fire, her being on one level brings me peace of mind. Question: today, are nursing home “standards” much better than in the past?
