Why is water system monitoring so important in central sterile processing?
First, it’s important to know who is responsible for the water system at your facility. One or more departments could have ownership or oversight of the water system, from facilities and maintenance to biomed and sterile processing. At the end of the day, the sterile processing department should have ownership of the quality of water being used in their process.
Inferior water quality can lead to numerous issues, including rusting, corrosion, discoloration and pitting of instruments. This can in turn lead to disposal, rework and can affect patient safety. Poor water quality can also cause issues with the washers themselves, leading to frequent or unplanned maintenance and downtime.
Monitoring the system to make sure the basic water quality parameters are being met is critical to system performance. Continuous remote monitoring ensures the water quality is consistent and meets or exceeds the guidelines set forth by the Association for the Advancement of Medical Instrumentation (AAMI).
Can you explain the AAMI TIR341 Guidelines around water system maintenance and monitoring?
Most sterile processing professionals are familiar with the AAMI TIR34 water quality specifications but are less knowledgeable about the section devoted to monitoring water quality, which includes parameters and suggested frequencies for testing and service.
This section also defines the specific variables you should be checking for: hardness, pH, resistivity and testing for bacteria, TOC and endotoxins. It is also important to monitor the pressure drop across filters, noting any abrupt changes that could be indicative of an issue.
What can SPD professionals do to meet these guidelines?
Sterile processing professionals should familiarize themselves with the water system maintenance and monitoring section of AAMI TIR34. They can also partner with a provider that has in-depth knowledge of the guidelines and can provide subject matter expertise on water treatment, maintenance and monitoring.
This can provide peace of mind that their water system is operating within the current guidelines. It also reduces the need for personnel to routinely check the water system for quality and performance metrics, giving more time back to focus on their primary objectives.
