According to the CDC, sterilizers should be tested at least weekly and every load that contains an implant. How often should sterilizers be spore tested?Ī. Crosstex/SPSmedical is used and recommended by leading sterilizer and instrument manufacturers. Crosstex/SPSmedical provides three different mail-in spore testing products to choose from, including the PassPortPlus, which provides immediate information about the Steam sterilization cycle, allowing failures to be detected before the spore test results have been communicated by the test laboratory. Upon request, Crosstex/SPSmedical provides a complimentary educational program, “Cleaning, Packaging and Sterilization of Instruments” which is based on sterilization best practices and is approved by IAHCSMM and CBSPD for continuing education credit. Crosstex/SPSmedical is a corporate member of both AAMI and CSA, where we contribute to writing sterilization standards. How is Crosstex/SPSmedical different than other test laboratories?Ī. Always follow the sterilizer and Bowie-Dick Test pack's instructions for use on cycle parameters for testing.Frequently Asked Questions Q. However, it does indicate that the programmed exposure time should be between 3.5 and 4 minutes. Step 4: Run the cycle. ANSI/AAMI ST79 does not provide specific guidance on cycle parameters for the test. If the cart is not included, the result could be superheated steam and a failed test. Only the sterilizer cart (on medium and floor loader sterilizers) should be present for a proper test. The drain is where the vacuum is drawn, and any residual air in the chamber will naturally migrate to the test pack. Step 2: Place the test pack. A Bowie-Dick Test pack must be placed on the bottom rack of the sterilizer, or sterilizer cart, directly over the chamber drain. It is the most common step missed, resulting in unnecessary downtime. Step 1: Perform a warm-up cycle. This is a critical step needed to properly heat up the sterilizer and can result in false failed Bowie-Dick Test results when not performed. The Bowie-Dick Test procedure is the same for both qualification and routine testing. Bowie-Dick Tests are also used each day the sterilizer is in operation, and only one passing test cycle is required for routine monitoring. This is qualification testing and requires three consecutive test cycles with passing results. Bowie-Dick Tests are used to qualify sterilizer performance when first installed, anytime it is moved, and following a major repair. View the STERIS University course How to Run a Bowie-Dick Test Recommended use of a Bowie-Dick Test is outlined in the Association for the Advancement of Medical Instrumentation's (AAMI) guidance ANSI/AAMI ST79 Comprehensive Guide to steam sterilization and sterility assurance in health care facilities. Interested in Earning Continuing Education (CE) Credit?Įarn 1.0 CE Hours by learning about Bowie-Dick tests and the key considerations when selecting a Bowie-Dick test for your facility. The Vacuum Leak Test programmed on your autoclaved only measures the integrity of the sealed pressure vessel and associated piping to assure air is not being admitted to the sterilizer during the vacuum draw downs. This is not possible and supports why air-removal tests are still very relevant to today’s modern sterilizers for autoclave testing. Sensors would need to be placed within the packs exactly where the NCG would either be trapped or collected in order to detect it. These gases act like a shield between the steam and the item, potentially shielding bacteria and preventing proper sterilization.Įven today’s sterilizers are not capable of detecting NCG because it could be hiding anywhere in the chamber. As the name indicates, non-condensable gases do not condense when touching a colder item. Air within a steam sterilizer is often referred to as a non-condensable gas (NCG). To fully answer why this test is still important today, we must first understand why it is important to remove air from the sterilizer. These air removal tests have been improved over the years, but you may be wondering, are Bowie-Dick tests still relevant in sterilizers that have programmed leak tests?
