My wife doesn’t do notes in front of patients, but as a consequence she spends several hours at home after her shift finishing up notes from memory. She does it because she works in the ER and it allows her to handle more patients (she hates it when patients have to wait 3+ hours so she does everything she can to get them seen quickly). It is definitely much more work for her to do it that way though.
Even if it did work, the notes for future doctors and insurance companies have very little overlap with what you’d say to a patient.
And physical exams have a ton of manual components where a doctor is just palpating things and asking if that hurts or this hurts or feeling if a lump is freely moving, or whether someone can rotate something at a specific angle etc…
Without the doctor annotating exactly what they are doing and what the patients response was every step of the way, the LLM would be missing too much data to really be useful.
