CRCST Chapter 14 Practice Test: Point-of-Use Processing

Some situations require instrument processing outside the Central Service department — in the OR, clinic, or procedural area. This chapter addresses immediate-use steam sterilization (IUSS, formerly called flash sterilization), its indications, limitations, and the documentation required. IUSS is intended for emergency situations when no other sterile item is available, not as a shortcut due to insufficient instrument inventory. The chapter covers the specific cycle parameters, required monitoring, transport protocols for unwrapped items, and the regulatory position statements from AAMI, TJC, and CMS regarding IUSS use. You will learn why IUSS items cannot be stored for later use, why they require careful handling during transport, and how facilities should minimize IUSS reliance through adequate instrument inventory.
