For medical device reprocessing department (MDRD) staff, confidence in the sterilization process is of prime importance. The results of their work can gravely affect patients, the medical staff who care for these patients, and the facilities in which these patients are being treated. Choosing the right products and methods to sterilize medical instruments is serious business.
How can these valuable tools help give you the confidence you need?
Detecting sterilization process failures
Saturated steam is a critical requirement for successful steam sterilization of medical instruments. Any air in the sterilizer chamber during the sterilization process can compromise the process.
PCDs are used to assess the performance of the steam sterilization process by providing an equal or greater challenge than the most difficult item routinely sterilized. They may use different physical designs to create a rigorous challenge to the sterilizer, but they must consistently detect sterilization process failures caused by air in the sterilizer chamber.
Canadian standards for PCD use
PCDs should be used in every sterilization cycle to provide an ongoing assessment of the efficacy of the process.
According to the Canadian Standards Association’s CSA Z314.3-14, “A biological indicator contained within a PCD shall be used to test each sterilizer with a full load every day that the sterilizer is used.” But without the right challenge, the results you get from a BI may be misleading.
CSA Z314.3-14 states that the biological indicator PCD can be either a commercially manufactured product or an in-house prepared PCD. However, achieving consistency can be problematic with manually assembled PCDs, and inconsistently or incorrectly assembled PCDs can lead to false results, potentially putting patients at risk. To provide usable data, PCDs should be consistent in their makeup and physical characteristics from test to test. The standard notes that manufacturing controls used in preparing commercially available PCDs can make them more consistent in makeup and physical characteristics than a series of in-house prepared PCDs, and recommends choosing a commercially manufactured PCD and using it consistently.
The right challenge
With more than 40 years’ use in health care facilities worldwide, 3M™ Attest™ Brand Process Challenge Devices are a trusted, proven technology with a range of options to meet customer preference.
Compared to manually assembled PCDs, these pre-assembled, single-use PCDs present a consistent, accurate challenge and help minimize the opportunity for human errors.
Each 3M™ Attest™ Process Challenge Device has a quality control external process indicator that shows that the PCD has been processed, providing additional assurance that your process is correct. Single-use test packs each have a lot number to help simplify tracking. This helps you quickly identify the source of any processing failures and recall affected instruments.
With their consistency, ease of use, traceability and ability to minimize human error in the important steam sterilization process, 3M™ Attest™ Process Challenge Devices can help you save valuable resources, time and money.
