How I Doctor with Dr. Graham Walker

Offcall

I built MDCalc 20 years ago because I wanted to save myself and other doctors time and make it easy for them to integrate more evidence into their medical care. Now I’ve launched Offcall to tackle something even bigger: giving doctors back our autonomy — through salary and workload transparency. These ideas shouldn’t be radical…but here we are. I still practice emergency medicine, but I’ve spent my career breaking out of the cookie cutter version of “what a doctor looks like” or “what a doctor’s supposed to do.” That’s why I started How I Doctor: a podcast about the most creative and influential physicians and how they’re rewriting the job description. Medicine wasn’t built for creativity. But I think that’s exactly what it needs. If you’re looking for new role models, different stories, or just proof that fulfillment is still possible in this era of medicine — this show’s for you. Welcome to “How I Doctor,” where we’re bringing joy back to medicine. If you enjoy the show, please hit the follow button! That will help us continue to bring you more great episodes every week.

  • 107 - Telehealth Isn't Enough for Rural Patients. Northwell's Dr. Chethan Sathya on Remote Monitoring, Home-Based Care, and Who Will Pay for It

    Dr. Chethan Sathya is a pediatric trauma surgeon at Cohen Children's Medical Center and Vice President of Strategic Initiatives at Northwell Health. In his first week as an attending, he operated on a six-month-old with a gunshot wound. The baby survived, and the case launched a second career: Chethan founded Northwell's Center for Gun Violence Prevention, built the We Ask Everyone firearm risk screening protocol that is now available nationally through Epic, and worked on All the Empty Rooms, this year's Oscar winner for Best Documentary Short.

    In this episode of How I Doctor, Dr. Graham Walker sits down with Chethan to ask whether the public health playbook that moved gun violence into the clinical workflow can work on a different problem: why a patient in rural Iowa or Kansas can't see a specialist. Chethan helped launch the National Specialty Care Access Coalition, a health system led group of more than 20 systems, and he argues the answer isn't more video visits. It's tech-enabled care that reaches patients where they live, through remote monitoring, home-based care, and upskilled primary care, paired with payment models that keep local hospitals open.

    Along the way they dig into why nuance matters in gun policy, how to screen more than 400,000 patients without judgment, why virtual care outside of stroke still lacks reimbursement, the licensure barriers that keep specialists from crossing state lines, and the tension between hospitals as businesses and as community lifelines.

    The technology to reach rural patients largely exists. The harder question is who will pay for it.

    What You'll Learn in This Episode

    Why Chethan treats firearm risk like a vital sign, and how a harm reduction approach has made gun owners the program's biggest supportersWhy mass shootings, suicides, accidental injuries, and urban violence need different policy responsesWhy tech-enabled care is more than telehealth, from remote patient monitoring to specialists taking quick referral touchpointsWhy reimbursement is the real barrier to rural specialty access, and how to incentivize local hospitals to surviveHow state licensure and credentialing barriers limit physicians who want to see patients across state lines

  • 106 - Most Patients Have Never Heard of Direct Primary Care. A Doctor on The Traitors Is Changing That with Dr. Jay Vinnedge

    Most patients have never heard of direct primary care. One family physician is introducing it to them from a downtown Oklahoma City clinic and now from NBC's The Traitors: New Blood.

    In this episode of How I Doctor, Offcall co-founder Dr. Graham Walker sits down with Dr. Jay Vinnedge, a family physician and former Air Force flight medic who opened The Little DPC in 2023 with his wife Danielle, a PA. The two talk about how Jay filled his panel by speaking candidly on social media about what's broken in healthcare, why he caps new patients so same-day access stays real, and what changes when a practice has no billing department and no volume treadmill. Jay also gets specific about the math: a small rented office, an affordable EMR, and a breakeven point he puts at around 20 patients.

    From there the conversation turns to The Traitors. Jay explains why he applied, how reading what patients leave unsaid carried over to reading other players, and what the show gave him that he didn't expect. It closes with Jay's message for employed physicians weighing a leap, and a look at whether direct specialty care could follow where DPC has led.

    What You'll Learn

    Why Jay built his audience on social media and why patients arrive feeling like they already know himHow removing insurance from the visit eliminates billers, coders, and the pressure to see more patientsWhat Jay's breakeven math looks like for a small DPCWhy Jay limits new patients to one a day and is hiring a second physicianHow reading what patients leave unsaid shaped Jay's approach to The TraitorsWhy Jay tells physicians weighing a leap that their MD or DO is a safety net, and why he believes most don't see the revenue they generate

  • 105 - Meet DR GPT™: Dr. Harvey Castro on Patients, Robots, and Who Will Drive AI in Medicine

    By the time your patient reaches you, you may be their fourth opinion. They have already asked a chatbot, or several, and they arrive with a diagnosis, a drug name, and a level of confidence you did not create.

    In this episode of How I Doctor, Offcall co-founder Dr. Graham Walker sits down with Dr. Harvey Castro, an emergency physician, MBA, and one of the most visible physician voices on AI in healthcare, known as DR GPT™. Before he became an AI evangelist, Harvey owned and ran freestanding emergency departments in Texas, with a payroll he personally guaranteed. He wrote one of the first medical apps for the iPhone, then wrote a book on ChatGPT in healthcare days after it launched, against the advice of friends. His message to physicians is simple: treat AI output as a draft, not a decision, and keep the clinician accountable for making the call.

    Harvey and Graham get into what changes when patients show up with an AI first opinion, and why Harvey worries about both bias in the models and patients self-treating. He makes the case that generative AI is mostly a communication tool, from discharge instructions as coloring books to coaching physicians on bedside manner. He describes the personal digital twin he built from his wearables, genetics, labs, and medical record, and why he believes patients, not hospitals or governments, will drive the next wave of AI. Graham pushes back on whether the next generation will really prefer a robot to a human doctor, and the two debate what happens to the role of physicians over the next 50 years.

    The conversation closes with rapid-fire takes, including whether ambient AI scribes are overhyped, why Harvey calls the human in the loop a scapegoat in the loop, what he thinks is the biggest mistake medicine could make with AI, and the one thing he says AI should never touch.

    What You’ll Learn

    Why patients arriving with an AI first opinion creates new risks around bias, self-treatment, and physician liabilityHow generative AI can improve communication across languages, cultures, and ages, and even coach doctors on bedside mannerWhy Harvey believes patients, not hospitals, will drive AI adoption, and what a patient “Bill of Rights” for AI could look likeWhy “human in the loop” can really mean “scapegoat in the loop”Where Harvey draws the line on what AI should never do

  • 104 - Primary Care Is the API for Healthcare. So Why Is Nobody Building for It? with Jefferson Health’s Dr. David Nichols

    Primary care doctors spend their days stitching together a system that was never built to connect. Dr. David Nichols thinks they should be the ones to rebuild it.

    In this episode of How I Doctor, Dr. Michael Hobbs sits in for Dr. Graham Walker to talk with his friend Dr. David Nichols, a family physician who finished residency in 2023 and became a medical director at Jefferson Health a year later. David co-founded a value-based care company at 23, ran its technology side through medical school and part of residency, and now leads AI work inside a large health system. He explains why primary care is the API for healthcare, the connector that fills every gap between specialists, hospitals, and patients’ lives, and why that connector is so poorly built.

    From there, Michael and David get practical. David shares how clinicians can start building, what makes an AI project stick instead of stalling after phase one, and why hours saved is a risky way to measure AI when saved time can quietly become more patients on the schedule. They also dig into a billing structure that pays doctors only when patient and physician share a room, physical or digital, and never for the thinking and coordination that make care safe.

    What You’ll Learn

    Why David calls primary care the API for healthcare, and why he says it is poorly writtenHow to start building if you’re a frontline clinician, from finding builders in your own network to meetups and online communitiesWhat separates AI projects that stick from pilots that stall, and why Jefferson’s boss prefers the term phase oneWhy AI scribes may not save time but can still improve the quality of a visitWhy doctors are not paid for coordination, asynchronous work, or cognitive thinking, and what David would change

  • 103 - Is Not Asking About ChatGPT the Next Malpractice Risk? With Berkeley Law's Vincent Joralemon

    Your patient asked a chatbot about their medication before they asked you. If something goes wrong, the law may care less about what the chatbot said than about whether you asked.

    In this episode of How I Doctor, Offcall co-founder Dr. Graham Walker sits down with Vincent Joralemon, director of the Life Sciences Law and Policy Center at Berkeley Law. Vincent is a former high school biology teacher who went on to law school at Berkeley and Harvard. In his recent paper in npj Digital Medicine, “Who bears liability when AI gives bad prescribing advice?”, co-authored with Julia Etkin, he argues that the learned intermediary doctrine works differently depending on whether AI sits behind the clinician or advises patients directly, and that clinicians may be required to screen patients for AI-sourced prescribing advice. Graham expected the answer to be technology companies, but Vincent’s argument lands back on physicians.

    Vincent explains the learned intermediary doctrine, the legal principle that already makes physicians the filter between drug manufacturers and patients, and why the same logic is likely to govern AI. He and Graham work through what happens when a physician follows an algorithm, when one overrides it, and how a note explaining your reasoning can be the strongest protection you have. They also get into whether asking “What did ChatGPT tell you?” is on its way to becoming a standard of care question, what de-skilling means in legal terms, and what a physician should do when a hospital mandates an AI tool they know is flawed.

    The conversation closes with rapid-fire predictions, including a malpractice case that names both a physician and a chatbot company, and Vincent’s answer on the biggest legal mistake a physician can make with AI right now.

    What You’ll Learn

    Why the learned intermediary doctrine is the foundation of AI liability for physiciansWhy patients’ tendency to trust chatbots more than traditional sources may change a physician’s duty to ask about themHow to protect yourself when you override an AI recommendation, or follow oneWhat the law may expect of you when your hospital requires a tool you believe is faultyWhy Vincent expects settlements before court decisions, and a physician and chatbot company named in the same suit
