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.

   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.
