When is the last time your facility reviewed your Quality Assurance practices for Vaporized Hydrogen Peroxide (VH2O2) Sterilizers? Is your facility’s VH2O2 Sterilization Quality Assurance Policy and Procedure up-to-date? Is your policy and procedure aligned with current published standards and guidelines like AAMI and AORN?

ANSI/AAMI ST58:2013 Chemical sterilization and high-level disinfection in health care facilities and 2016 Edition AORN Guidelines for Perioperative Practice, Guideline for Sterilization have up-to-date recommendations for the use of VH2O2 Sterilizer monitoring tools including physical monitors, chemical indicators (CI), and biological indicators (BI).

Typically, VH2O2 sterilizers are frequently used and instruments are returned to patient use. A robust Quality Assurance program includes routine efficacy testing using state-of-the-art monitoring tools. Per AAMI ST58:2013, a CI should be used on the outside of each package unless the internal indicator is visible. An internal CI should be used inside each package, tray and containment device to be sterilized. A PCD with the appropriate BI should also be used at least daily, but preferably in every sterilization cycle. AORN’s Guideline for Sterilization is more specific and recommends using a test BI daily on each cycle type, preferably with every load. Read and compare your practices against our summary table.
