What happens when the people saving your life are dying inside?

I spent 17 years training to be a vascular surgeon. Then I wrote a book about what that training does to doctors, and to patients.

Disconnected comes out November 10. 🫀

@bschermd Thank you so much @bschermd ! I have so appreciated your support on this journey. 🙏🏼🙏🏼🙏🏼

[Bret Scher, MD @bschermd]

For those who know @lilyjohnstonmd, you already know her intellect, her balanced discussions, and her passion for metabolic health. But now with her newly published book, we learn so much more about her journey of becoming a surgeon and the toll it took on her life and identity. You don't have to work in medicine to appreciate it and resonate with her journey of chasing a dream only to get it and realize maybe she was chasing the wrong thing all along. I highly recommend her book Disconnected!

SO thrilled to be a return guest with @realDaveFeldman on TFP! It was an amazing conversation, if I may say so myself. :)

special guest Lily Johnston (MD) @lilyjohnstonmd
Part 1 of 2

Lily Johnston goes into the "three lies" of informed consent, real talk on physician suicide, and how we've gotten to such a broken medical culture in the US.

🏥 What vanished between medicine then and now?
⚖️ Why does eminence outweigh evidence in research?
🧠 How do cognitive biases mirror the WMD failure?
💊 What did WHI actually prove about hormone therapy?
📋 Why can't a patient ever truly consent to surgery?
🔪 How does OR culture silence those it harms most?
🩺 What breaks when doctors aren't allowed to be human?
✈️ How does medicine compare to aviation on safety?
📉 Why do licensing boards punish doctors for seeking help?
😶 What does a room's silence reveal about surgical culture?
💔 When does trying to help a patient become part of their harm?
🫀 Why does Johnston's first rule say surgery is for other people?

Is my plaque changing? Not reliable yet for small plaque. Even expert labs see ~25 mm³ of scan-to-scan wobble, and one scanner setting can mimic a statin effect.

Tracking? Wait 2–5 years. Same scanner and software.

My CCTA is pending. Full breakdown: 🎥

Three AI programs read the same heart scans. 🫀

One said plaque fell 48%. One said it rose 21%. One said it barely moved.

Thank you @theproof for sharing your data so openly. It made the perfect case study.

So can you trust an AI heart scan? ↓

Depends on the question you ask it. 🔍

Chest pain? SCOT-HEART's 10-year data: fewer heart attacks, same number of stents.

No symptoms? One small screening trial, and it was negative. Two big ones are running.

@happyhexer In an ideal world, that’s the plan. Unfortunately my hospital call schedule and travel throw a wrench in this. I am tentatively planning to do this month’s AMA on Thursday evening this week! We will confirm that by Monday and post here and on YT with details

[Lily E. Johnston, MD MPH @lilyjohnstonmd]

@monza160 That’s awesome, thanks @monza160 !

Thank you @AmplifyPubGroup for bringing it to life, and @DominicDAgosti2 for reading it early.

[Lily E. Johnston, MD MPH @lilyjohnstonmd]

The house of medicine is on fire. Another 30-minute module on extinguishers and stairwell evacuation won't fix what's burning.

Let's talk about the real problems. I do in DISCONNECTED.

Out November 10. Pre-order below. 👇

80 hours a week? Send me to Azkaban.

The father of American surgery ran on cocaine. We still train surgeons his way. I've spent over a decade in that system.

@Fat_Electrician told the story. Draconia Malfoy reacts at 7 PM PT. 🐍

Slytherin isn't a house. It's a surgical residency.

Ambitious. Cunning. Built by a man running on cocaine and morphine.

Draconia Malfoy has entered the OR. 🐍 Tomorrow: the dark history of how we train surgeons.
