The group that I work for as an emergency physician publishes a quarterly newsletter. I guess they are pretty strapped for contributors. So dire is their need for articles they asked me to write something. They even let me pick the topic!
So I thought it might be interesting to write a short review of modeling and simulation in emergency medicine. The audience are practicing emergency physicians – real world doctors pretty far removed from the shadow of the ivory tower. If possible, the article should be entertaining and relevant for practising EM doctors. Also, it should be short. They don’t have the column space or patience for my usual verbose ramblings.
The famous (in EM circles) Joe Lex hosted a Speakers’ Corner at the ACEP (American College of Emergency Medicine) meeting in San Francisco in 2002. He gave an open invitation for speakers to give short talks on the last day of the conference. As you know, only the most hardcore conference attendees stick around for the last
day. Only the most masochistic of these would sit through unsolicited talks. Happily, I had a very nice group of doctors attend my talk, which was an introduction to modeling and simulation, and a short discussion of how and where these techniques were being applied within the field of emergency medicine.
The talk and PowerPoint presentation was very well received. In fact, I had hoped that I might be in the running for the Speakers’ Corner award. As of yet, however, no reward, plaque, or check has been forthcoming. If I did indeed win that award, perhaps someone could let me know? I am starting to think I did not win.
Modeling and simulation have been used for the following:
1. modeling flow through the emergency department – recent work has used barcodes and RF tags to literally track patients’ progress through the department and its ancillary areas in an attempt to streamline throughput
2. simulation training – residents as well as nursing and other staff are using more and more types of simulation in training scenarios. One program has a manequin that is hooked to a monitor that students practice ACLS (advanced cardiac life support) with. It responds to treatments (meds) with changes to vital signs and presentation, and proceedures such as direct laryngoscopy, endotracheal intubation, central line placement, and CPR can be performed on it.
