A recent study listed mistakes by doctors and nurses as the third most common cause of death in the United States.
According to researchers at Johns Hopkins, there were more than 250,000 deaths annually caused by medical errors over an eight year span.
Hartley Thompson, a University of Maryland graduate, is trying to change that. He's the president of B-Line Medical, a company that produces software to improve the delivery of healthcare.
Thompson joined Kelly Swoope on ABC2's In Focus to show how he's created technology to train doctors and nurses to catch mistakes before they happen.
