Okay, let's dial it back a bit here on medical treatment.
1. When you go into an actual emergency room (not a doc-in-the-box clinic), you are faced with a triage situation. You are "triaged" based upon both what you tell them and your appearance. The more serious patients, even those that came in after you arrived, go first. For instance, based upon the described symptoms, a likely heart attack (forget Hollywood's depiction of someone having a heart attack) will be taken back as quickly as possible and you, if you have say, a few broken bones will go after him/her. A large laceration that required a tourniquet will go ahead of your flu or broken arm or ankle or leg. If you came in with a bad cold or flu, guess what, you will be waiting a long time.
I went into an emergency room with abdominal pain; after waiting around for an hour, a nurse interviewed me and had a tech come down and draw my blood. After another hour, they came out and rushed me to surgery for a ruptured appendix. The problem with emergency rooms and even the "doc-in-a-box" places, is that too many people go in with colds, mild cases of the flu, headaches, twisted ankles and bruises. Add to that there's a percentage of "drug seekers" looking to get a fix and an assortment of the mentally ill individuals having psychotic episodes.
All this these take hours to wade through.
I have heard that France has an extremely pro-active socialized medicine system that their people were very satisfied with. However, since the influx of millions of migrants it has ruined that system.
Socialized medicine systems are designed with the established population base in mind and grow proportionally with the "slow gradual" growth of the population and aren't meant to handle huge influxes of individuals seeking treatment.
