What does explainability in AI image interpretation really mean—and is it even what physicians want? Happy to share this collab in Nature @SciReports, led by @AndreaStoras & @kelkalot, re: explainability in GI endoscopy, w/ lessons for other fields https://t.co/RhlUk4O607

🚨 ATTN. New Jersey: MIKIE SHERRILL… - Refuses to commit that she won’t raise New Jersey’s sales tax. - Her plan will “cost you an arm and a leg, but if you’re a good person, YOU’LL DO IT.” As Governor, Mikie Sherrill will make YOU PAY! Vote AGAINST her on 11/4.

Re-upping this great 🧵 by @DrLaurenOR- very relevant to GI #AI Endoscopic diagnosis can involve translating probabilities into binary choices. Should that dichotomization be in hands of the doctor or software developer? Should CADx display "% certainty" or JUST a prediction?
This discussion was getting long, so I thought I'd lay out my thoughts on a common argument: should models produce probabilities or decisions? Ie 32% chance of cancer vs "do a biopsy". I favour the latter, because IMO it is both more useful and... more honest. IMO: 1/13

Thanks to @EricTopol for highlighting our latest study, which looks at some of the failure points in the clinical reasoning performance of reasoning models. What does this mean for the future of diagnostic decision support? And can LLMs actually medically reason? A 🧵⬇️
The performance of generative A.I. models for clinical reasoning are not holding up to increased scrutiny https://t.co/b21JfvTNbf

Fascinating talk @ASGEendoscopy AI Summit. New questions - ✅who regulates medical AI? ✅ Who is responsible for harm? ✅ Physician deskilling?

@tberzin presenting @ASGEendoscopy | “International Webinar on GI Emergencies” “When you write the endoscopy procedure note - describe the lesion AND add the risk of rebleed”…nonGIs may not know and it helps to understand …to poke the bear or not? …poke? #GItwitter

There's a gold mine of great material in those musty old, bound medical journals that may be sitting in your division conference room...

Nice demonstration of ‘push technique’ for deploying Axios inner flange in *small spaces*: ➡️ unlock BOTH catheter lock & stent deployment hub ➡️ stabilize stent deployment hub against chest with two fingers ➡️ push Axios forward, keeping stent deployment hub *fixed in position*

@tberzin I definitely think at least in this snapshot in time there’s a role for both. For trainees, open evidence can be dangerous if you’re using it as a primary source for decision making. It’s GREAT as a search engine for guidelines and very rarely hallucinates citations

Would love if some GI folks could post some examples of errors that crop up in Open Evidence. UpToDate also has *occasional* errors, out-of -date recs, and controversial opinions. Would be interesting (but difficult) to compare the two for accuracy across range of criteria.
@GI_Pearls I’ve picked up so many errors in open evidence that I stick to up to date to look things up. OI I use for patient information and literature searches mostly. Maybe things will get better

For medical trainees in any interventional or surgical field, I'm not sure there's a more important lesson than this one.

Et tu, OpenEvidence? AI's "jagged edge" problem in medicine: it may draft an incredibly nuanced clinical plan, while failing at counting the 'o’s in colonoscopy. LLMs don’t reason—they predict. Brilliant at times, brittle at others. Use with vigilance. @GaryMarcus

Masterful handling by my mentors @tberzin & @Boston_Endo —“Godfather of Cholangioscopy”—at Beth Israel, showcasing AI for safe EUS gallbladder drainage (1:10) & the Dragonfly cholangioscope (1:50). Game-changing! 🚀 Hope to soon showcase this together from Saudi. 🇸🇦 @EndoscopyOA
