David Woods BSc (Hons) provides an insight into the various test methods available for washer disinfectors to ensure the quality of reprocessing activities.
Choosing the right test method for a washerdisinfector is not a straight-forward task. The user can be presented with a range of test kits from multiple manufacturers and laboratory methods can vary depending on which guidance or version is followed. Tests on water quality can have big implications and are critical to ensuring the process remains safe and effective.
Testing allows the user to detect things that cannot be seen by eye: proteins, bacteria and chemical impurities. Making a decision may require the user to get information from the supplier or laboratory and seek the opinion of an AE(D). The decision involves knowledge of the science and guidance involved and pressures of cost and time may be a factor. With technologies rapidly evolving it is vital that the correct choices are made and the necessary information to make those choices is available to all parties involved.
Most of the time these technological advances are positive and can save vital time and money for the Trust, but how would a user know they are getting the same quality of test? This is a key consideration as any contamination, be it protein or microbial, needs be flagged up accurately and in a way that is compliant with the guidance. Historically, there have been several examples where a method of testing has become popular ‘in the field’, due to ease or cost, only to be found ineffective when guidance changes.
