What if an AI could write your medical chart—and what happens when it gets it wrong? Doctors have long lamented the paperwork that comes with every patient encounter. “Charting was the bane of my existence,” admits Dr. Laura Hagopian, an emergency physician who’s spent countless hours piecing together fragmented notes and outdated records. Could artificial intelligence finally lift this administrative weight?

Recent advances in large language models promise to generate discharge summaries as accurately as seasoned clinicians, potentially returning precious time to the bedside. By training on thousands of patient encounters and lab reports, these systems can stitch together coherent narratives of care—micro-diagnoses, treatment plans, and follow-up recommendations—at a speed no human chart-writer can match.

Yet with speed comes risk. When an AI hallucination slips into a diagnosis and becomes enshrined in a patient’s record, who is accountable? Dr. Hagopian highlights the stark difference between human and machine error: “I feel very different about a human making a mistake compared to an AI making a mistake.” As trust in automated documentation grows, so too do questions about responsibility, oversight, and patient safety.

In this episode, AI researcher Vasanth Sarathy and Dr. Hagopian peel back the layers of these complex issues. They explore the nuts and bolts of AI summarization algorithms, discuss promising clinical trials, and weigh the ethical dilemmas of delegating clinical judgment to code. How do we ensure that efficiency doesn’t override accuracy when every data point can mean life or death?

Whether you’re a clinician craving relief from chart fatigue, an AI developer pushing the boundaries of what’s possible, or a patient curious about who’s really recording your health story, this conversation offers a vital look at the future of medical documentation. Join us as we navigate the promise—and the pitfalls—of letting machines tell our most critical health narratives.

What if a 19th-century nurse laid the foundation for 21st-century disease surveillance?

Florence Nightingale, widely known for her compassion, was also a pioneering statistician who used data to reveal a hidden crisis: more soldiers in the Crimean War were dying from infections than from battle wounds. Her insights led to life-saving reforms—and sparked a revolution in how we understand public health.

Today, that same spirit of data-driven action lives on through artificial intelligence. In this episode, we explore how modern AI systems are transforming outbreak detection by scanning signals across the digital world—social media, search trends, news in multiple languages, even environmental data—to identify early signs of emerging health threats.

From tools like HealthMap to natural language processing engines that monitor disease mentions across continents, AI has already proven its value by detecting outbreaks like H1N1 and COVID-19 before official systems sounded the alarm. But history reminds us that data can be misleading: Google Flu Trends famously overestimated flu cases by mistaking media buzz for actual spread.

That’s why the most powerful systems today pair AI with human epidemiologists, combining rapid pattern recognition with expert judgment. It’s a modern-day continuation of Nightingale’s legacy—a partnership where algorithms spot weak signals, and people decide how to act.

This episode uncovers how statistical thinking has evolved into intelligent surveillance, offering public health leaders a critical advantage: time. Time to act, time to intervene, and time to prevent the next outbreak before it becomes a crisis.

What if the next breakthrough treatment for a rare disease was already sitting on the pharmacy shelf?

Drug repurposing, the science of finding new uses for existing medications, is transforming how we discover treatments, blending serendipity with strategy. It began with surprises like Viagra, a heart drug turned blockbuster, but today it's driven by advanced data tools that accelerate discovery and reduce risk.

We explore how knowledge graphs (vast maps of biomedical relationships between drugs, genes, and diseases) are now at the core of this revolution. When paired with artificial intelligence, these networks can surface overlooked connections buried in decades of medical literature. Unlike opaque algorithms, these AI systems can explain why a drug might work for a new condition, providing testable hypotheses and building trust with clinicians.

This approach doesn’t just save time—it can save lives. Traditional drug development takes over a decade and billions of dollars. Repurposed drugs, having already passed safety checks, can reach patients faster and cheaper. That’s a game-changer for rare and neglected diseases where time and resources are limited.

This episode is a journey through beautiful mistakes and brilliant methods, showing how multidisciplinary teams, from data scientists to clinicians, are reshaping the future of medicine. Join us to learn how technology is turning chance into choice, and uncovering new hope in old drugs.
