CASE STUDY
CLIENT: Laser Spine Institute Cleveland, OH
Use discrete event simulation in facility design validation before starting construction. Industrial and Systems Engineers are playing a more prominent role as the healthcare industry looks to provide higher-quality, cost-effective care. In healthcare facility planning, discrete event simulation can determine the impact of varying layouts and new work flows before knocking down a single wall, saving valuable time and money. EXECUTIVE SUMMARY
SERVICE: Transformation
Recently, Laser Spine Institute (LSI) in Cleveland, Ohio, decided to extend its services
METHOD: Design Validation
by building satellite facilities across the country. These new facilities are smaller than the existing facility, and operate using a slightly altered process flow. To determine the appropriate space requirements for the new, smaller scale model, Array built a
Challenge
discrete event simulation model.
Sometimes a process looks good on paper, but does not function as expected. When there are a number of variables in play, each with a distinct distribution, it can be difficult to predict how a system will react.
Two major project goals were to confirm that patients could recover completely in a PACU room without causing other patients to wait in the operating room, and determine whether the space was large enough to bring in an additional surgeon, potentially leading to the treatment of more patients. The study began with patient flow observation, allowing the Healthcare Systems Engineer to gain an understanding of the ambulatory surgery center’s operations. Array captured input data using the system’s electronic medical records; we
Solution
used validation and verification techniques to ensure the simulation accurately
Array used a simulation study to determine whether the newly designed process was optimal, and whether the number of rooms was adequate for the patient volume the outpatient spinal surgery center hoped to serve. Basing the process design on efficient practices leads to an easier implementation of productive work flows, staff movement and patient routing.
