There are a few other reasons - doctors document every interaction partly for medico-legal reasons – just in case something happens. The notes become especially long and defensive in any situations that have a possibility of being misinterpreted. If it's not written down, it didn't happen. It's obviously also a record for other clinicians / healthcare professionals to read through and see what happened during the admission.

But yep I do worry about any kind of generative AI in this context.
