Everyone you love should have a medical advocate while they’re in a hospital. I personally know many horror stories where people were killed or injured by medical malpractice. It’s hard when you don’t have a medical background but perhaps there is someone you can call to double check medications, treatments, etc. At least knowing that someone is watching can keep the hospital staff on their toes.
