I had to visit the ER recently. I did not want to go but my doctor insisted. A family member who is also a doctor also insisted I go.
The ER was eerily empty. The ER doctor saw me immediately. There were only a couple of other patients that I could see. This contrasts to prior experiences in the ER where there is a long wait as I get triaged, with lots of people waiting to be seen.
Fortunately my situation was nothing serious. When I returned home and told my relative, he said his hospital's emergency department was also very light. In his opinion, there were a lot of people going to the ER who didn't need to go in the first place.
Edit: I am referring to non-trauma related admissions to the ER. E.g. I have a headache and I am going to the ER to be seen now.
