One of the most difficult things about working in the emergency department was making a phone call.  Not just any phone call, but a call at midnight, or 2 a.m., a call to a parent who might be waiting for his teenager to return home from an evening out with friends.  A call that would change a family forever.  A call that no one ever wants to make.  A call to say “I am calling about your son.  He has been in a car crash and is in the emergency department.  Can you come to the hospital? . . .  Is there someone who can come with you?”  It is the call that parents dread, and that we dreaded making.  And, it is a call that doesn’t have to happen.
