I am surprised that people are surprised by this finding, and support your position.

Anecdotally, doctors get things wrong quite frequently. Almost everybody has a bad medical diagnosis/advice story. The amount of reference material that a doctor needs to know off-hand and the data that they are given to make a diagnosis makes it a really difficult job. They also seldom have the ability to know whether their diagnosis/treatment worked, so have a limited ability to 'learn' from outcomes. (I did some work for cancer research and one of the most difficult problems was trying to get 'end of treatment' data because the end of treatment was often an unknown, to the researchers, death).

The ability to have a 'prompt' that includes lab data is likely to be better than the opinions of a doctor that only has one person's professional experience, limited ability to interpret 'prompts', and needing map it to an in-memory conditions database.
