IANAD [doctor] and missed that in the sea of jargon - but I think your question actually clarifies how the LLM got confused. I wouldn't necessarily say "more general than vision," but more severe. There's a big difference between "unaware of objects" and "difficulty seeing or distinguishing objects."
It looks like GPT-4 disregarded "unaware of objects on their left side" in favor of more clinical (but less specific) information later in the question: "two hours after the accident, there was a left hemianopia." According to Dr. Wikipedia, "hemianopia" is a vague term that could indicate partial loss of vision, or could only affect one eye. But the patient's informal description sure doesn't sound like a partial loss of vision, nor did he say "left eye." The information of "left hemianopia" needs to be considered alongside what the patient self-reported - it confirms and clarifies what the patient said - but the LLM didn't seem to do this.
There's other implicit information that the LLM would have trouble leveraging:
- the problem is so serious that a 35-year-old with a 20-year history of migraines immediately went to the hospital, so I would be very reluctant to dismiss it as a migraine related to the "stress of the accident."
- when I hear "unaware of objects on their left side" my gut reaction as someone with a brain is "that sounds like brain damage, you need to go to the hospital."
- Even with its limitations, GPT-4 should have realized "two hours after the accident" meant that it wasn't a temporary migraine-related hemianopia. Apparently it didn't. But I think this is amenable to specific training. The other two things are not, but they are the kind of thinking doctors rely on.
- IanCal 3y agoThanks for the info. > when I hear "unaware of objects on their left side" my gut reaction as someone with a brain is "that sounds like brain damage, you need to go to the hospital." To be fair, the answer it gives is "a stroke". (For anyone who hasn't looked at the supplemental files the answer is E).
