Sterile Processing Water Management Program for AAMI ST108 Compliance

A. Gaps often show up at the point of use. Water treated upstream may not be verified consistently where it’s used in instrument reprocessing. Other breakdowns include inconsistent sampling, unclear ownership across teams and limited visibility into performance over time.

A. ST108 outlines a more structured, risk-based approach. It includes defining water types (utility, critical, steam), establishing baseline data and moving to routine chemical and microbiological testing. It also drives closer coordination across SPD, Facilities and Infection Prevention.

A. Water should be fit-for-purpose at the point of application (final rinse, ultrasonic cleaning or steam). This typically includes defined sampling locations, consistent testing protocols and visibility into water quality where devices are processed.

A. Teams may be asked to produce a clear, end-to-end record of their program, including water management plan, sampling schedule, test results, excursions and documented response actions. Surveyors are looking for continuity over time and evidence the system remains in a state of control.

A. Many teams know they need to prove control, but don’t yet have a clear, connected way to do it. The pressure comes from survey readiness, unannounced reviews and the need to align a multidisciplinary water management team around a single, defensible approach.

A. Critical water is used in final rinse and other high-risk steps in medical device reprocessing. It is generally held to tighter quality specifications and should be monitored consistently for fitness for use at the point of application.
