Agenda Simulation Process Redesign Sample Emergency Project Clients
Simulation – What is it? Mathematical representation of real life Model generation on simulation software Queuing theory Randomization and variation Input process information Outcome statistics Scenario model to compare outcomes
Simulation – Project Steps Collect data Define current process Develop model of current process Compare model outcomes to real-life Define changes Develop scenario models Compare scenario to model outcomes
Simulation - Data Volumes Average and Peak Daily Visits, Arrival by Hour Types Walk-In/Ambulance, Acuity, Discharge/Admit/Transfer Activity Times Triage, Evaluation, Tests, Disposition Waiting Times Test Results, Renege/Leave Without Being Seen Locations Triage, Beds Staff Schedule Physician, Nurse, Tech, Clerk, Registration
Simulation - Patient Volume Daily average visits in 2007 Monthly range from to 163.6
