I'm unaware of any. I have a close family member who ran the human services department for the third largest county in the state and then had an appointed leadership position over long-term care for the state. The biggest challenge he faced was being hamstrung in being able to fire negligent and abusive long-term care workers. A sampling taken from many examples: a worker who routinely slept in a patient's bed and the patient's toiletries during his shifts. Numerous workers caught stealing from patients. Most egregious: staff at one facility who starved a patient to death. The poor woman weighed 80 pounds at death, due to their callous negligence. None fired immediately after these incidents. All due to work rules. Would you get fired from whatever your job was if you had killed someone due to negligence on the job? Would you have been fired if you had been stealing from your customers or employees?
There's a misconception out there that Americans are sue-happy. To the contrary, most never even consider suing, even when it's entirely justified, as in casses like these. I wish there were more lawsuits involving long-term care patients. First, because it's the right thing to do. Second, to bring to light the absurd work rules that protect abusive workers in this area.
