See IM-7981 for Simulation Model

Clone of Clone 4of IM 27348, of JPS IM-27150 of original JPS IM-14117 See reference in diagram notes. WIP for Environment part of primary care regional model

A Medical Imaging View of Patient Flows through ED Imaging Workup. See IM-375 for an extended map

Clone of IM-10536 WIP for LHN Individual Hospital O Month of October 2013, with joined up flows

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.

WIP to explore hybrid modelling of a regional health service. Where should services be located in a network of hospitals? What are the performance measures? This is a simple initial model of some Transfer options

Extension of IM-14144 with ward outliers as a prelude to a modular ward dynamics framework. Should include ideas in IM-1008 For backlog and services see IM-8382

Causal Loop Diagram of the Dynamics of Emergency Department Overcrowding

Rich picture version of published simple model representation described as a capacitated processing model, modified to separate Patient Flow from workflow.

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

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.  

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-10714 WIP for LHN Individual Hospital O Month of October 2013, to which insights of IM-11079 and IM-7981 are being added here

A work in progress model for ED daily average flows based on reported statistics by triage category with all triage categories aggregated See IM-663 for a more annotated version

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
