Perhaps someone signed a waiver. Based on the rest of the story I don’t think we can assume they are telling the truth without any evidence here.

Completely agree. It's the sort of case that their should be jail time, just not financial consequences.

Jail time in a system where responsibility is so diffused won't happen.

Front-desk has a signed waiver? Good luck proving that it was the person on shift at the time who forged it, she doesn't remember what happened a year ago, and the existence of the fraudulent waiver isn't proof that she authored it.

Nobody's responsible, and nobody's accountable. There's a legal requirement that someone at the hospital should have done their jobs, but there's no legal requirement that forces someone particular to do them.
