Adverse events — when bad things happen to patients because of what we as medical professionals do — are a leading cause of suffering and death in the U.S. and globally. Indeed, as I have written before, patient safety is a major issue in American healthcare, and one that has gotten far too little attention. Tens of thousands of Americans die needlessly because of preventable infections, medication errors, surgical mishaps, and so forth. As I wrote previously, according to Office of Inspector General (OIG), when an older American walks into a hospital, he or she has about a 1 in 4 chance of suffering some sort of injury during their stay. Many of these are debilitating, life-threatening, or even fatal.
