Uncertainty in Medicine: Root Causes with Ronald Wyatt, MD

विवरण

What does uncertainty in medicine have to do with Chernobyl? According to patient safety officer Dr. Ron Wyatt, more than we might think. In the fourth episode of our "Uncertainty in Medicine" series, he draws a chilling connection between one of history’s worst nuclear disasters and the quiet, preventable tragedies that unfold in hospitals every day. In both cases, the warning signs were there. People sensed something was wrong. But no one spoke up—or if they did, no one listened. Through his work at the Joint Commission, Dr. Wyatt has spent decades investigating sentinel events, the most serious and avoidable medical errors. What he’s found is deeply unsettling: the root causes rarely come down to lack of knowledge. They come from cultures where fear, hierarchy, and silence override curiosity and caution. And time and again, he’s seen how racism and bias magnify that silence. Here, Dr. Wyatt reveals what truly makes healthcare safe—and what has to change to protect every patient, equally.
