I have found it very useful to discuss possible diagnoses and diagnostic steps with the LLM before going to the ER. Once there, I told them what my expectations were along with the rationale for it. They agreed with 80% of it.

Ultimately the ER was of no use in treatment, but the preparation did help rule out a serious diagnosis.

What could possibly go wrong.

This is precisely the thing that LLMs are great for: spicy auto-complete.
