Simulation model version of IM-398 CLD (which lists the reference).The dynamics of emergency and elective admissions competing for vacant ward beds in a hospital. Here Bed Capacity is a fixed parameter. For an adjusted bed capacity stock see IM-8862.For backlog and services see IM-8382

Clone of IM-11079 ED Model for Daily ED Performance with 2 areas again, as in the previous IM-10571. Focus on shift performance by Specialist.

Dynamics of Emergency Department Crowding Initial Simplest Simulation of the View from the waiting room. Start of a simple introductory series which proceeds to IM-338  A simple CLD is at IM-340

Simplest ED Model for Daily ED Performance with 1 ED area rather than 2 in IM-10571. Currently runs over a weekend and calibrated roughly to Weekend Data. ED completion rate may be better as a converter.

A work in progress model for ED hourly arrival flows based on reported statistics by triage category with individual triage categories dis-aggregated using vectors. Based on a hospital performance report from  http://www.bhi.nsw.gov.au/publications/hospital_quarterly_3

Dynamics of Emergency Department Crowding Initial View from the waiting room. Follows from IM-369 Sim and IM-340 CLD. Proceed to IM-349 

   When patient census is low the hospital decreases staff. In addition to staff shortage they implement new protocol to attempt to reduce incidents. However, this act aggravates patients, decreases staff productivity, causes injuries, and decreases overall productivity.   

Physician agents interacting with delegate agents for emergency department assessment diagnosis and treatment. From BMC paper May 2013, combining figs 1 and 2

Based on combining IM-7670  with IM-7671 (WIP based on June WA Teleconference) plus indirect effects

Simplest ED Model for Daily ED Performance with 1 ED area rather than 2 in IM-10571. Currently runs over a weekend and calibrated roughly to Weekend Data.Ward net discharges are extended in IM-12414. The Master Version of this, with the story added is at IM-11936

WIP for regional integration based on NHPA and IHPA activities in Australia built on clone of IM-10198 and will need to also focus on Elective Emergency Interactions Models esp Simple Simulation IM-7981

The transitions from potential to undiagnosed and diagnosed intellectual disability of people with ID from birth to death in order to plan future services as they survive longer. See IM-3279 for updated version with different age splits

WIP Patient Flow improvement strategies for a City Hospital with 3 years historical data and two year planning horizon. Built after a Generic Teaching Hospital Model IM-10346 A simplified stock flow map is at IM-399

Dynamics of Emergency Room Crowding with treatment spaces. Here we investigate the effect of constrained spaces and ignore any changes in treatment time or staffing effects. Many of the consequences occur before treatment with potential arrivals being turned away and arrivals leaving without being treated.

This is a high level system dynamics model which is built to determine the dynamic relationships of the FSA and Followups capacity. Therefore, it can help clinicians to find out the optimistic method in order to reduce the waiting list. At past clinicians were seeing more FSA patients, however, after few months, the followups patients overwhelmed the clinics. Therefore waiting list has been built up again. By running this model, clinicians can find out the balanced leverage point(s).
