If I was a lawyer for the hospital I'd use that as evidence that she deliberately left without having the catheter taken out, with the premeditated intention of suing.
Yep if you followed my line of questioning earlier, that was exactly my assessment. I ask the adversarial questions going in. Then you already have the answers the other side will want and can decide if you want to invest money in a lengthy contingency case, especially against a hospital whose pockets are deeper than a solo practicioner.
