Multidisciplinary approach to optimizing immediate use steam sterilization (IUSS) workflows between the operating room and sterile processing departments: A case report

Background: Immediate Use Steam Sterilization (IUSS), formerly known as Flash Sterilization, is a rapid process that allows the timely sterilization of surgical instruments in the event of accidental contamination. The infrequency of use and dependence on expedited reprocessing raised concern over omitting essential steps such as pre-cleaning, decontamination, weighing, and biologically verified sterilization cycles. Methods: A multidisciplinary systematic workflow analysis was conducted utilizing Lean A3 methodology to reduce IUSS inefficiencies and enhance evidence-based guideline compliance. Results: Revised IUSS workflows and protocols were implemented, focusing on effective communication, adherence to evidence-based principles for all IUSS processes, and delegating infrequent tasks to subject matter experts in the Sterile Processing Department. Conclusions: Attempts to reduce the utilization of IUSS have proven effective. Due to these efforts, perioperative managers may face the challenge of dealing with outdated workflows that are no longer being utilized frequently enough to allow perioperative staff to become familiar with them and develop the necessary skills. The IUSS workflows should be subjected to process improvement methodologies to adapt them to optimize performance while minimizing risks to the organization.
