  • Title: Design and validation of a critical care simulation model.
    Author: Lowery JC, Martin JB.
    Journal: J Soc Health Syst; 1992; 3(3):15-36. PubMed ID: 1391741.
    Abstract:
    The high costs of building, equipping, and staffing critical care beds, coupled with more restrictive reimbursement policies, are forcing hospital administrators to seek ways for determining accurately the number of critical care beds needed. Existing critical care bedsizing models do not capture the complexity of today's critical care environment, nor have they been formally validated using actual hospital performance data. The study described herein was designed to address these needs. A GPSS/H simulation model was developed and validated, and includes the flow of patients through the study hospital's operating rooms, post-anesthesia recovery unit, three intensive care units, and two intermediate care (stepdown) units.
