Your doctor can call
If you’re going to the emergency room during your regular physicians’ office hours, you can call him and have him call the ER so they can fill out a pre-expect form. This is what the triage nurse at the ER would have filled out. If your doctor calls it in in advance, you can skip that nurse and see a doctor sooner. If you’ve told your doctor about other recent medical changes, he can tell the ER doctor those as well.
