GeriPal - A Geriatrics and Palliative Medicine Podcast · The Promise and Pitfalls of AI in Medicine: Bob Wachter · 18 Apr 2024 podcast

I don't know that it's gonna be better than you, but if it doesn't have to be better than you, if it's as good as you at a fraction of the cost and available 24-7, that's a really, really useful tool.

I'll say one more thing about hallucinations.

I don't know if you saw this, but

Uh Sarah Murray, who's now our chief health AI officer at UCSF Health, and who knew two years ago we needed a chief health AI officer, but we now have one.

Put into GPT three point five maybe eight or ten months ago, please write a prior authorization to the insurance company.

I want to use a anticoagulant, like a Pixaband, a DOAC, for my patient with an insomnia.

Now, that of course is wacky.

That is ridiculous to be using a blood tinner for a patient with insomnia.

The thing just wrote this beautiful, absolutely beautiful, well constructed prior authorization request of the insurance company.

And it said, in my experience, I've used this many times and it really works well for my patients.

And although you know it's a little unconventional, the literature is increasingly supportive of this use case.

Sarah read this and she was.

So flabbergasted that she went on to PubMed to search whether she'd missed some recent literature.

Of course there was not.

Six months later, she came back and put in the exact same request into GPT-4.

And it said, there must be some kind of a mistake.

There's no use of this medicine for this purpose.

And it would be unethical for me to write this for you.

So, you know, it it these things are getting better fast, and they will continue to get better fast.

And I think the hallucination problem is very real, but it's already better than it was, and I think it's going to continue to get better and better.
