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

WIP for Effects of Senior Staff Weekend Rostering on ED Flows. Two areas Map simplified later to no specific areas Simulation in IM-11079

Simplest ED Model for Weekend  ED Performance with 1 ED area IM-11079  Ward net discharges are extended with Ward and Waitlist inflow and outflow details (informed by IM-7981) WIP

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 launchpad for patient flow insights for flows through the emergency department and hospital, including the broader community context. It also includes links to other insights relevant to ED flow improvement.
