Travis Zack on OpenEvidence and the Future of Medical AI

How can medical AI help doctors make better decisions while preserving clinical judgment and human connection? Travis Zack, MD, PhD, an oncologist, researcher, and chief medical officer of OpenEvidence, joins The Future of Medicine to discuss the future of AI in clinical care. OpenEvidence is an AI-powered platform that helps clinicians find and understand information from peer-reviewed medical research, clinical guidelines, and other trusted sources. In this episode, Zack explains why reliable medical AI depends not only on avoiding fabricated information, but also on finding the right evidence for each clinical question. He discusses how OpenEvidence is designed to bring relevant research into physicians’ workflows while leaving the final decision in the clinician’s hands. The conversation also looks ahead to more proactive forms of care. Zack describes a future in which AI could identify meaningful changes in a patient’s health or in the medical literature and alert physicians before the patient’s next scheduled visit.  Zack also shares his research using language from medical records to improve cancer care. By analyzing how patients describe symptoms such as chemotherapy-related nerve damage, researchers may be able to better predict when treatment should be adjusted to prevent lasting side effects. Together, Dr. Zack and host Errol Ozdalga, MD, explore whether reliance on AI could weaken physicians’ skills, how medical education may change, and why human reasoning and empathy will remain essential to medicine. They also consider a central question for health systems: Will AI be used only to increase efficiency, or will some of the time it saves be returned to patients?

Michael Osterholm on Pandemic Threats, Public Trust, and the Future of Vaccines

Michael Osterholm, PhD, MPH, one of the world’s leading experts on infectious disease threats and pandemic preparedness, joins The Future of Medicine for a wide-ranging conversation about COVID-19, vaccines, airborne transmission, public trust, and what the world must do before the next pandemic arrives. Osterholm is director of the Center for Infectious Disease Research and Policy at the University of Minnesota and has spent nearly five decades investigating outbreaks and advising public officials. In this episode, he reflects on the experiences that first inspired him to become a “medical detective,” including an unusual outbreak linked to thyroid tissue entering the food supply through hamburger meat. The conversation then turns to COVID-19 and the lessons that remain unresolved. Osterholm explains why he believes the United States needs an independent, nonpartisan review of its pandemic response—one focused on identifying what worked, what failed, and how changing evidence shaped decisions about schools, hospitals, masking, and public gatherings. “The pandemic clock is ticking,” Osterholm says. “We just don’t know what time it is.” He also discusses why public health guidance must be able to evolve. As Osterholm puts it, “Science is not truth. Science is the pursuit of truth.” New variants, new evidence, and changing risks do not necessarily mean earlier recommendations were made in bad faith; they reflect the reality of responding to a rapidly developing threat. Watch the full conversation to learn what COVID-19 revealed about the strengths and weaknesses of modern public health—and how science, vaccines, and more honest communication could help the world respond differently next time.

Michelle Mello on AI, Insurance Denials, and the Future of Health Policy

Dr. Michelle Mello, professor of law and health policy at Stanford University, joins The Future of Medicine for a conversation about one of the most frustrating and consequential parts of American healthcare: prior authorization. For many patients and clinicians, prior authorization is the process behind the letter saying an insurance company will not cover a medication, procedure, or service unless additional criteria are met. As Dr. Mello explains, this system is already difficult, time-consuming, and often painful for patients and care teams. Now, artificial intelligence is beginning to reshape how these decisions are made. In this episode, Dr. Mello and host Dr. Euan Ashley discuss how insurers and healthcare systems are using AI in prior authorization, billing, appeals, and utilization management. AI may be able to speed up routine approvals and reduce administrative burden, but it also raises serious questions about transparency, bias, accountability, and whether patients are being protected from wrongful denials. The conversation explores what Dr. Mello describes as an “arms race” of AI systems, with insurers using technology to evaluate requests and health systems using their own tools to identify denials most likely to be overturned and draft stronger appeal letters. She also explains why appeals matter: a large share of insurance denials can be reversed, but many health systems do not have enough staff to appeal every case. Together, Dr. Mello and Dr. Ashley consider what responsible AI governance should look like in healthcare, why simply banning AI may not solve the underlying problems, and how AI could be used in ways that support patients, clinicians, and fairer decision-making. They also discuss the need for greater transparency from insurers, the role of private governance, and why academic medical centers have a responsibility to help shape the safe and ethical use of these tools.

Anthony Fauci on the Lessons of HIV/AIDS, COVID-19, and The Future of Pandemic Preparedness

Dr. Anthony Fauci, former director of the National Institute of Allergy and Infectious Diseases and one of the nation’s most influential public health leaders, joins Stanford Department of Medicine’s The Future of Medicine for a conversation with Dr. Euan Ashley about science, service, public trust, and the future of public health. In this episode, Dr. Fauci reflects on his early career as a physician-scientist, the first years of the HIV/AIDS epidemic, the creation of PEPFAR, the scientific foundation behind COVID-19 vaccines, and the challenge of communicating evidence in an era of misinformation. Together, Dr. Fauci and Dr. Ashley discuss what it means to lead with integrity when the stakes are high, and why long-term investment in science remains essential for pandemic preparedness and medical progress.

Christopher Murray on the Global Burden of Disease and the Hidden Threats Facing Humanity

Dr. Christopher J.L. Murray — health economist at the University of Washington, physician, and founder of the Global Burden of Disease framework — joins The Future of Medicine to discuss what decades of data across 204 countries reveal about human health, and where it's headed by the end of this century. Dr. Murray's Global Burden of Disease project involves 19,000 collaborators in 167 countries and has produced more than 5,000 published papers. In this conversation, he explains what that data shows: remarkable progress on childhood infectious disease and HIV, a profound global shift toward chronic conditions like heart disease, diabetes, and chronic kidney disease, and a mental health crisis — rising steadily for over a decade — whose causes experts still actively debate. He also discusses why the widely circulated claim that American obesity rates had flattened is likely a statistical artifact, what the data projects for the coming decades (including diabetes overtaking heart disease as the world's leading cause of death), and the compounding health crisis facing the Sahel as population growth, poverty, and climate change converge. The conversation closes on the Lancet Commission on existential and catastrophic risks — a project Dr. Murray helped initiate that takes a data-driven look at long-range threats to humanity, from AI and synthetic biology to nuclear risk, out to 2100. It's a rare conversation that takes a long, honest look at the future — and doesn't flinch. Thank you for listening!
