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

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

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

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

Extension of IM-7981 with dynamics of daily ward discharges and did not waits. For an adjusted bed capacity stock see IM-14144.For backlog and services see IM-8382

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

Backup of IM-11079 before shared editing for merging storytelling. 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

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.

Unfolding causal loop diagram story of hospital congestion from Eric Wolstenholme's more detailed explanation of hospital congestion IM from March 2022 Youtube video and online stella presentation. Use of cascading interlinked archetypes. See Kumu version,  early discharge boundaries IM for an earlier version and Generic Archetypes IM from Gene Bellinger

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

   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.   

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
