That's the most likely, since she and her family definitely knew about the infection. She had been given a heavy course of antibiotics, was not responding to treatment, etc. I'm sure they're just trying to get as much money as possible out of the hospital, although it may or may not be the hospital's fault .
It's a horrible thing and I'm not criticizing her, although I suspect that a trial lawyer is going to end up with most of "her" money.
"...trial lawyer is going to end up with most of "her" money."
and she'll be a victim twice over.
It isn't easy to successfully sue a hospital because of an infection. Proving where you got the infection is difficult and finding a doctor or hospital employee to testify against the hospital is not an easy task. Usually the "expert witnesses" have to be doctors from other states because they don't want to testify against someone they will be passing in the halls or on the golf course.
I recommend that anyone who has surgery get their medical records from the hospital and doctor's office. It can be expensive if you had a long stay and complications or cheap if the stay was short. But, if there were complications you might never know it until you read it in your chart. By law they have to provide you with your records; but, they do charge for them. The fee is approximately $1 per page for the first five or ten pages then 25 to 50 cents for each additional page. Yes, it can be expensive; but, the information can be PRICELESS.
