Causal Loop Diagram of the Dynamics of Emergency Department Crowding Initial View from the waiting room 

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

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.

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.

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

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

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

Simulation model of the WIP Conceptual map IM-7671 of initial scope of the effects of the ED 4 hour rule based on June WA Teleconference and IM-8221. See also the conceptual maps of addition of indirect effects at IM-7775 and the potential wider context map in IM-6167

Patient flow through ED at the end of life

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 insight IM-11936 is the Master Version with the story added. The previous running model, now without a story, is at IM-11079
