Dialysis Machine and Reprocessed Dialyzer Disinfection SOP: What the Log Must Record

Dialysis Machine and Reprocessed Dialyzer Disinfection SOP: What the Log Must Record

A dialysis shift is a sequence of handovers: the machine finishes with one patient, is disinfected, and starts again with the next one, sometimes inside the same half hour. The SOP that governs those handovers and the log that records them are the first two documents an auditor asks for.

Canadian guidance splits the machine into two parts, each with its own disinfectant level. The treatment station has a third set of surfaces, and waste leaving the station follows the provincial biomedical waste rules.

What does the machine disinfection SOP have to state?

It states which surface group is treated, with which level of disinfectant, at what point in the turnover, and against what the machine itself reports.

How does the log stay defensible?

A log with a tick and a signature records only that someone was in the bay. A defensible log records the machine, the session, what was treated, with what, for how long and who did it, so the answer to "was this machine disinfected after the previous patient?" can be reconstructed a month later. Where the machine prints its own cycle report, that report is filed with the log rather than replacing it.

What changes when a dialyzer is reprocessed?

A reprocessing programme for haemodialysers has its own Canadian standard in the CSA Z364 family, the reuse of haemodialysers standard, and a programme that reuses dialyzers follows that document for the process, the labelling and the records, including what identifies the dialyzer as belonging to one patient and how many times it has been used. The published hepatitis B guidance adds the exclusion that overrides the rest of the programme: a dialyzer used on a hepatitis B surface antigen positive patient is not reused on anyone.

Programmes running single-use dialyzers still answer to the same quality management standard for the training, monitoring and records around the machines, so the difference between the two models is the dialyzer paperwork, not the machine routine.

What leaves the station?

Waste is segregated at the point of care rather than pooled at the end of a shift. Provincial rules put sharps, including needles and syringes, into a rigid sharps container with a yellow label bearing the universal biohazard symbol, and blood-contacted waste into its own labelled stream. Gloves worn for patient care and for touching the patient's equipment are changed between patients and are not washed for reuse; nitrile examination gloves and isolation gowns are consumed continuously through a shift. Red infectious waste bags hold the blood-contacted stream, and the sharps containers at each bay are exchanged on a fill line rather than when someone notices they are full.

Ordering for a clinic, lab or care home? Wholesale and multi-site ordering covers account setup and case pricing, and the B2B wholesale collection lists the lines stocked for institutional buyers. Units standardising consumables across bays can start from the cleaning and disinfecting collection.

Frequently Asked Questions

What has to be disinfected on a dialysis machine, and to what level?

External surfaces are cleaned and disinfected with a facility-approved low-level disinfectant before the machine is used on another patient. After a hepatitis B surface antigen positive patient, the internal surfaces, or pathways, get a high-level disinfectant before the machine goes to another patient.

What happens if a patient's hepatitis B status is unknown at the first treatment?

The machine is not used on another patient until both internal and external surfaces have been cleaned and disinfected. The hemodialysis guidance is explicit about that sequence, which is why a first-treatment protocol is written before the patient arrives.

Can a dialyzer be reprocessed and reused?

Reprocessing haemodialysers has its own Canadian standard in the CSA Z364 family, and programmes that reuse dialyzers follow it for process and records. One point is absolute: a dialyzer used on a hepatitis B surface antigen positive patient is not reused on anyone.

What does the disinfection log have to record?

Machine identifier and treatment bay, patient or session reference, the surface group and disinfectant level, the agent and its concentration, the contact or cycle time, the start and finish time, the operator, and the machine's own cycle report where it prints one.

How do the station surfaces and waste fit in?

After treatment, every surface in the station is cleaned and disinfected with the facility-approved agent: the bed or chair, the table, the doorknobs and the television remote. Waste is segregated at the point of care, with blood-contacted waste and sharps in their own labelled containers under the provincial biomedical waste guideline.
