Simulation Presentation to Design May 21, 2008

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

Simulation - Patient Arrival  Pattern of arrival by hour

Simulation - Locations Current  3 Triage  5 Fast Track  30 Beds  12 Overflow beds
