ANN ARBOR, Mich. Every year, more than 115 million patients enter emergency rooms at hospitals around the nation. And more than three-quarters of them leave with an impression of what happened or what should happen next that doesn't match what their emergency care team would want.

"It is disturbing that so many patients do not understand their post-emergency department care, and that they do not even recognize where the gaps in understanding are. Patients who fail to follow discharge instructions may have a greater likelihood of complications after leaving the emergency department."
