“ED? Do you mean ER? ED means something else to me. :)”
From reliantemergencyroom.com:
“The ED is a larger hospital section dedicated to emergency care, featuring multiple specialized rooms and areas for addressing severe symptoms like minor burns and traumatic injuries. On the other hand, the ER is the initial area within the ED where patients are triaged and first assessed.”
In British books and films, people with injuries and sudden illness are often taken to the Emergency Department.
Ok thanks
