Closed claims database/stats for DNP project

Hello! Can anyone point me in the right direction here? Getting started on my DNP project and I’m looking for stats on intraop emergencies- most specifically those covered in the Stanford emergency manual. I have to be searching wrong or these things are hidden in the darkest corners of the internet. I am trying to search for closed claims data but am struggling to find what I’m looking for. Has anyone been successful here? Any tips? Resources you know of to get me where I’m trying to be? Thanks!
