It is no coincidence that Epic, one of the largest EHR vendors, was named after literary “epics,” heroic poems defined by their extreme length. A study from the University of Wisconsin found that one in five patients has an EHR the size of Herman Melville’s Moby Dick, more than 206,000 words. “[Generative AI] is an opportunity to add a layer of simplicity on top of the Moby Dick-sized amount of information in a patient’s chart,” Adams said.
