Our new paper with Sonali Sharma and @RoxanaDaneshjou is out in @npjDigitalMed! We examine how medical safety and disclaimer messages in public LLMs have changed over time when answering patient questions.
Generative AI models are giving fewer medical disclaimers over time. 📉 In 2022, ~26% of AI health answers had a disclaimer. By 2025? <1%. As models get smarter, they’re getting less safe. Patients may take outputs as medical advice. https://t.co/2OYQvKdezT

University of California faculty and alumni won five Nobel Prizes this week, setting a new record for the most faculty of one institution to achieve this great honor in a single year 🏅💙 💛 These remarkable achievement highlight the ongoing contributions of America’s #1

These discoveries span decades and disciplines, but they all have one important thing in common: They’ve all relied on competitive funding from the federal government.

Excited to launch our project on clinician-in-the-loop post-training methods for medical multimodal AI with @RoxanaDaneshjou and @tom_hartvigsen. Grateful to @NIH for supporting this work!
Good news! CPH's @_ahmedmalaa and colleagues @RoxanaDaneshjou and @tom_hartvigsen have received a grant from the NIH Director's office for work on participatory mutimodal AI and editable foundation models to improve diagnosis and tx. @BerkeleyCDSS @StanfordDBDS @UVA

One-liner summaries are central to emergency care, but generating them is cognitively demanding/time-pressured. We evaluated LLMs for automated one-liner generation & compared them head-to-head w/ physician summaries. New work w/ @MelMolinaMD, led by @nbgolchini @nikita_mehandru!
We show LLMs perform better than physicians in summarizing patient clinical information from the EHR as one-liners. One-liners are essential in emergency medicine, where providers make high-stakes decisions with limited information. @_ahmedmalaa @nikita_mehandru @nbgolchini

One-liners summarizing a patient's clinical state are essential in the emergency department. Not surprising that LLM's/GenAI do better than human doctors at producing these one liners

Medical disclaimers in AI outputs are quietly fading, but they matter for safety and trust! Our recent study on this topic is featured in a new MIT @techreview piece.

How has medical disclaimer messaging changed in generative AI models over the past few years? New work with Sonali Sharma and @RoxanaDaneshjou!
Brilliant student Sonali Sharma came to me with a question. If patients are using AI to answer their medical questions, are they being adequately warned by AI systems that it cannot provide medical advice? What we found surprised us!

New paper out in @NatureComms led by @cmuptx 's team! We study how generative AI models can enable accurate medical image segmentation even with limited labeled data.
🚀 Excited to share that our work GenSeg has been published in Nature Communications! GenSeg is an end-to-end, downstream-task-guided framework for generating synthetic training data for medical image segmentation. It significantly reduces the need for manual annotations — by a

individual reporting for post-deployment evals — a little manifesto (& new preprints!) tldr: end users have unique insights about how deployed systems are failing; we should figure out how to translate their experiences into formal evaluations of those systems.

What more could we understand about the fractal, “jagged” edges of AI system deployments if we had better ways to listen to the people who interact with them? What a joy to work w @jessicadai_ using individual experiences to inform AI evaluation (blog/ICML/arXiv links 👇)
