Note my comment above (above the above one). My closest hospital and former employer did make a built-in emergent care next to the ED as a triage chic, but they ended up not using it and still referring the cases through the ED. Afraid of missing something, or all the pts c/o chest pain to get in quickly.
Yea, I saw that comment

But it seems that it is put into practice more during my US ER time.
It greatly reduces the burdon of the ED, and as I witnessed, was staffed with IM and Peds docs which made it function more efficently even for follow ups. It also allowed more than "temporary" treatments as people started using it as their form of primary care since the docs were the same.
What really brought it into its own though was 24 hour operations. Many people who need medical care also have to work, which makes the hours wasted in the docs office obsolete. As well as having more convienient hoursof operation. 10-3 might work for a doctor's schedule, but it certainly doesn't work for most of the working population. Especially those without adequete insurance who not only lose paying a deductable or full cost, but also the lost wages from the missed day of work, which brings the visit without tests into the hundreds of dollars.
Why even bother going to a PCP when you could pay $90 for urgent care and follow up there at your convenience?
Furthermore, if you find something sinister (other than us left handed people), you can simply cart them over to the ED or admit them to the hospital.
IM and Peds have direct admit capability unlike most EMs, so their patient flow really flows.
I have also noticed how efficent it works in the Euopean countries that don't have EM as a specialty. Docs can follow up during their ED hours, especially in the evenings, and the direct adit capability takes a lot of the advanced diagnostic workups out of the ED.
It is yet another reason why I htink EM as a specialty is something of a farse. (Not to say they are not outstanding doctors, they are just seemingly only useful in the US system, and a change towards efficency could render them obsolete.)
