Despite not having used SIMUL8 or other simulation software before, Raul was able to build a simulation within just a few hours, modeling the entire patient ED process; from pre-registration, triage, the treatment of the patient, final registration and through to departure. The simulation also utilized existing ED data, including median times for total stay, to enhance the accuracy of the results.
As more patients arrived in the simulation, LWOT rates were displayed, as well as acuity levels - a measurement of the intensity of nursing care required by a patient, with one being the highest level and five being the lowest.
At current patient arrival rates, the ED were seeing 78 patients per day on average, with a LWOT rate of 1.7%. However, with ED patient volumes increasing by 10% each year for the last four years, the team knew the maximum 2% LWOT threshold rate would likely be crossed, unless department processes could be changed to accommodate this increase.
