On/Offcall: What Physicians Get Wrong About AI in Healthcare, According to UCSF's Dr. Robert Wachter

Welcome back to On/Offcall!

Dr. Robert Wachter is an absolute legend in healthcare. As the Chair of Medicine at UCSF and a true pioneer in patient safety and digital innovation, he’s spent decades shaping how technology, policy, and clinical care intersect in the real world.
This week, we were honored to welcome Dr. Wachter to How I Doctor for a wide-ranging conversation with Offcall co-founder Dr. Graham Walker about how AI is transforming medicine. 👏Dr. Wachter’s new book A Giant Leap is about to hit shelves and it’s all about how AI will fundamentally transform healthcare (pre-order it here!). He’s convinced AI won’t replace doctors, but he’s equally convinced that it will force medicine to reckon with what humans should actually be doing, what machines might do better, and how we can redesign care without losing judgment, trust, or humanity.
From clinical decision support to de-skilling and documentation to trust, he and Graham dive first into every hot topic of how AI is reshaping the physician workforce, including:
🧠 How AI is already changing decision-making, documentation, and medical education
⚠️ Why “de-skilling” isn’t always bad, but blind trust in tech is
⏳ How the system’s dysfunction created an opening for AI that we can’t ignore
🛑 What it will take to adopt AI tools without losing clinical judgment, professional identity, or human connection
Out now! Listen to the full episode on Offcall

NEW: Physician Spotlight With Dr. John Dayton, Stanford Assistant Professor, Intermountain Physician, & Healthcare VC!

5 questions with ER doctor and physician innovator Dr. John Dayton
1) John, what’s one boundary you wish you had set earlier in your career? I wish I had learned sooner that being available all the time doesn’t make you a better doctor, it just makes you a more exhausted one. This extends to doing work outside of clinical practice. When I started working with venture funds and advising digital health companies, I’d meet whenever they wanted. Often this led to me taking afternoon calls when I was in the middle of a set of night shifts. That basically meant I was meeting with them at 2AM. I didn’t have the confidence to change the time and I didn’t realize they were fine connecting in the early morning or late afternoon. Don’t make that mistake.
2) What AI tools have made the most impact on your practice and why? I’m a big fan of clinical decision support tools like OpenEvidence, Vera Health, Doximity’s DoxGPT and UpToDate Expert AI. I use these for particularly challenging clinical situations, but I also use them to personalize discharge instructions for my patients. Even though clinical decision support tools are sexy, as a healthcare investor and startup adviser, I’m particularly interested in AI operational tools, such as how AI can improve efficiency with clinical scheduling, improve workflows, and be used to provide patient summaries for transition of care.
3) What’s a health hack/routine you do personally that could benefit other doctors or your patients? As an emergency physician, I’ve started using wearables and trackers for my sleep, and made specific changes with my scheduler. It’s not safe to let your sleep-wake cycle be driven by Adderall and Monster drinks, and that’s pretty much what I did for the first 10 years of my career. As I’ve gotten older, I’ve also talked to my scheduler about reducing my day to night switches. He was great about letting me work a month of day shifts alternated with a month of night shifts. The catch was that I had to find another doctor in my group willing to have the opposite schedule. As you can imagine, this wasn’t a hard sell and this new schedule has been working out very well for us.
4) AI just prescribed medications autonomously in Utah. Should doctors be scared or embrace this?I have a hot take: Many are focused on physicians being replaced by this technology, however after I did a deep dive with Dr. Byron Crowe from Doctronic, I have a different opinion. Rather than replacing physicians, Doctronic has set up an augmented workflow for medical refills, which is a time intensive but low-cognitive load process. Just like we’ve protocolized management for several disease processes, Doctronic has a physician-driven protocol for medication refills that involves identifying the patient, identifying their medical history, has questions related to side effects and drug interactions, and has in-patient pharmacy-level checks. Rather than replacing physicians, Doctronic has built a physician-led process based on best practices, with physician-driven escalation and checks. My feeling is they’re actually setting a standard for how physicians should lead and oversee digital health and AI solutions.
5) Who do you want to nominate for the next physician spotlight?? As a physician who loves medical innovation, I’d love to hear from physicians who are building solutions as well as physicians who are funding those investments. This includes builders like Avo’s Dr. Yair Saperstein and Doctronic’s Dr. Byron Crowe as well as healthcare investors like Lightspeed’s Dr. Brenton Fargnoli and a16z’s Dr. Vineeta Agarwala.
