Yes- I am interested in SD application to bed management particularly in =
relation to getting patients through the Emergency department and into =
inpatient beds in a timely fashion-- am working on a model but =
proceeding slowly as I am a also a full time ER clinician

To Andy Mather-
With regard to your inquiry about flow of patients through an Emergency Room
and into inpatient beds, a simulation game developed by Bette Gardner called
Friday Night at the ER, deals with exactly these dynamics. Her address,
according to the SD Society Directory, is 17800 Woodland Avenue, Morgan Hill,
California 95037 USA Ive done a lot of modeling of patient flow in health
care systems (e.g., between primary care providers, specialists, and acute
inpatient care) and created simulation-based learning environments using these
models. I can tell you more about this work if you are interested.

At the London School of Economics we have just completed a piece of work
with a major London Teaching hospital which we will go public on in
January via the LSE Magazine. Additionally, I hope to present a paper at
the 1998 SD conference in Quebec. The details of that paper are shown
here:
> Looking in the wrong place for healthcare improvements:
> A system dynamics study of an accident and emergency department

> DC Lane, C Monefeldt and JV Rosenhead

> The London School of Economics and Political Science

> Accident and Emergency units provide a route for patients seeking
> urgent admission to acute hospitals. Public concern over long waiting

> the factors which contribute to such delays. In collaboration with a

> interaction of demand pattern, A&E resource deployment, other hospital

Hello John:
Only a few words to remember that you can find a single and easy
INFECTION MODEL in different sources: I think, Power Sim, Vensim
(Look the web address in
htpp://ourworld.compuserve.com/homepages/telinges/software.htm),
very instructive !
Best regards

Dear Colleagues:
Anyone on this list interested in a separate set of e-mail
"conversations" on system dynamics in health care? If so, please drop me
a note.

Concerning John Rodats suggestion for a separate conversation on SD in
health care.
John,
I dont think its a good idea to split the list. If there is a need for
a more efficient way of seeing which messages pertain to what topics,
perhaps we should move to an internet news group?

In response to Andy Ms inquiry about model patient flow through an ER.
We include a model that addresses the kinds of issues that your are
interested in with the ithink software. Its written up as a case study
in the Applications Guide. Also, the model included with the ithink demo,
which you can either download from our website, or get sent to you in on
a CD from the HPS Customer Service group. (# and URL are below. email for
CS is support@hps-inc.com.)
