After automation: AI will make uncertainty cheap to explore without making it cheap to resolve
Graham Walker, Emergency physician — AI can surface every rare possibility a doctor once considered and dismissed. The hard part for patients won't be finding information—it'll be knowing when low risk is low enough.

The Future of Clinical Decision Support Is Silence

These essays are intended to spark discussion about where technology is taking clinical decision support – and where physicians feel it should go. Blaring “Mary Had a Little Lamb” every 4–19 minutes from 2am to 4am in a fluorescent-lit ER has only two outcomes: insanity, or alert f

Doctors are losing in 2 very different courts this month: one in JAMA, and the other in Plymouth County. Weirdly, I think they expose the same mistake: We keep judging physicians by the tiny slice of medicine that outsiders can actually see.

I don't want to be too grandiose, but any technology you plan to bring into healthcare can kill people. With chemo or radiation, it's probably obvious. You can assuredly connect some of the dots with AI. blog.mdcalc.com/post/the-tr...

Doctors asking themselves "Am I gonna sleep well tonight?" is one of the most powerful ways we do medical decision making. Physicians carry a quiet internal test after hard decisions.

The #1 reason doctors are quitting medicine is that it's too much work... to do work. A new national survey asked physicians who'd left clinical practice early why they walked away. “𝗛𝗮𝘀𝘀𝗹𝗲 𝗳𝗮𝗰𝘁𝗼𝗿.”

Without attempting eye contact, the TSA agent told me “Sir, the computer selected you for enhanced screening" in a tone so flat and robotic that the computer might as well have said it itself. But she didn't surrender authority to the algorithm; her bosses stripped it from her by design.

For Pete’s sake, can a health system collab with Google Research/Google DeepMind already and run some real end-to-end studies already? They are consistently putting out some of the highest quality, most insightful, clinically sound research on GenAI and care delivery.
