Using RFID Technologies to Capture Simulation Data in a Hospital Emergency Department

Simulation professionals understand the importance of accurate data for model validation. Traditional sources of simulation data come from information technology systems, manual records from staff, observations, and estimates by subject matter experts. This paper discusses how radio frequency identification (RFID) technologies were used on a recent consulting engagement at a hospital. Data collected through RFID can validate or replace activity duration estimates from traditional sources. However, the accuracy and cost effectiveness of RFID is not guaranteed. A sound methodology was developed, which included rigorous planning and testing of hardware, processes and data analysis. Hardware vendors needed to understand what the simulation required so they could properly setup equipment and software. Also, ED staff needed to understand the purpose of this data collection to avoid anxiety about personnel evaluations. Finally, efficient and reliable issue and collection of patient tags was crucial to the success of this effort
