Washer or No Washer: The Record Your Positioning Accessories Need

Give every positioning accessory its own reprocessing record, and let that record carry one explicit verdict: approved for the washer-disinfector, approved only under the conditions written next to it, or not approved. Each record should name the item and its part number, the components it covers, the validated cycle in full, the rack and loading rules, the drying and inspection points, the manual method that replaces machine cleaning when the answer is no, and the revision that governs it. The same part number should appear on the item or on a tag that survives the process, and the record should live where the question is asked, at the washer. Once that page exists and can be reached, sterile processing stops asking. Until then the answer belongs to somebody’s memory, and no hospital policy can be built on top of a memory.

Why the Same Question Comes Back Every Week

A gel pad, an arm strap, a lateral support, a clamp: the technician holds the item, turns it over, finds no part number, and asks again. Someone half remembers that the blue ones could go in. The rep checks with the factory. The answer arrives as a message and is gone by the next shift. Nothing in that chain is written down, so nothing in it can be audited, taught to a new hire, or defended when an infection prevention round asks how the decision was reached.

The standards place the obligation on the maker. ISO 17664-1 sets out the processing information a medical device manufacturer is expected to supply, covering preparation, cleaning, disinfection, drying, inspection and maintenance, packaging, sterilization and storage. FDA guidance for reusable devices expects validated, device-specific reprocessing instructions rather than a blanket claim, and departments that work through AAMI ST79 meet the same idea from the other side, because the manufacturer’s instructions govern what sterile processing may run. AORN guidance for positioning aids lands in the same place: the aid is reprocessed as the maker instructs, and the department records what it did. The central sterile services department is where that instruction either becomes usable or becomes a phone call.

For a hospital this is not a policy gap. The department can only follow what the factory has validated, and it cannot validate a foam pad that nobody tested. Anyone who has been through CSSD capacity and equipment selection during a build or a refurbishment knows the assumption sitting under the planning numbers: that each item arriving at the loading dock has a page saying what may be done to it.

Much of what has been published on this question stops at the standard. The work that actually ends the question sits one level lower, item by item, and most of it is a writing job rather than a testing job for the parts a factory already understands.

One Record Per Item, Three Possible Verdicts

Three verdicts cover the practical field. Approved means the accessory may go into a washer-disinfector under the conditions in the record. Approved only under the stated conditions is where most positioning accessories live, because the permission is attached to a rack, an orientation, a temperature ceiling, a detergent class, or the requirement that a pad or cover come off first. Not approved means the factory has validated a manual or wipe-down method instead, and the record names the reason.

“Not tested”, “washer compatibility unknown” and “clean according to hospital policy” are not verdicts. Each one hands the decision back to the person holding the item, which is the situation the record exists to end. A statement of washer-disinfector compatibility per device that names neither the machine class nor the parameters has not answered the question.

The reason matters as much as the verdict. A restriction that names its cause, whether that is open-cell foam that holds water, an adhesive seam that lifts at temperature, a sealed cavity that cannot drain, aluminum components that react to a high-alkaline detergent, or a coated surface that crazes and then collects soil, gives the department something it can reason with. Staff will meet combinations the factory never imagined, and a rule with a visible cause survives contact with those cases better than a symbol in a margin.

The identity block ties the page to the physical item: product name, catalogue and part number, revision, and the table series or equipment family it fits. State what the record covers, the complete assembly or the individual pads, straps, covers, clamps, buckles, inserts and fasteners. Record the patient contact the item is expected to make, intact skin, non-intact skin, mucous membrane or sterile tissue, and whether it is single use or reusable, because that classification decides how far the reprocessing has to go. Then the approved equipment: washer or cart washer type, model if the approval is model-specific, rack or basket, adapter, orientation, and whether the item may share a load with other devices. Then the validated cycle in terms a department can compare against its own machine: pre-rinse, detergent class and concentration, contact time, temperature, rinse water quality, the thermal disinfection target, and drying conditions. Then load limits, the maximum count or weight, spacing, and whether stacking is prohibited. Then preparation before washing, the point-of-use wipe or soak, the maximum delay, which buckles open, which components separate. Then disassembly and reassembly, with the steps, the tools, and whether parts travel apart or together. Then material limits, cleaning chemistry, rinsing, drying, the manual fallback, inspection and acceptance criteria, the disposition of a failed item, any downstream disinfection or sterilization, the use-life limit, the validation reference, and the document control block. That reads like a lot. It is one page per part number, and read as a group those cells are the reprocessing section of the instructions for use, which is the part sterile processing actually opens when the delivery arrives.

The Identifier Has to Survive the Wash

A record nobody can connect to the item in hand is decoration. If the pad carries no part number, and the tray list shows a family name that covers four materials, the technician is back to guessing, and the guess will differ between shifts. The document has to point at the identifier and state where it sits on the item.

The identifier also has to survive the process it authorizes. A laser mark on a metal frame, a molded-in number on a polymer insert, or a tag rated for the chamber temperature keeps its value. An adhesive label chosen for looks rather than for the cycle will lift in the first wash, and once it is gone the item cannot be traced to a revision, a lot or a use count. If the identifier is a label, the record should say so, and say what happens when it fails.

Set a rule for accessories that arrive outside the original set: pads bought later as spares, a clamp added by a distributor, a superseded version still in the cupboard. No part number, no verdict. Where the factory has replaced a part with a new revision, the record should say whether the disposition changed, because a denser foam or a different adhesive can turn an approved item into a conditional one without anyone noticing at the bench.

Printing the answer is the last step, and it is the step that removes the phone call. Sterile processing works from a load card or a tray list at the washer, so the useful export from the record is one line per item: part number, disposition, cycle name. A page that lives only in a folder on the quality server, three clicks and one password away from the person loading the machine, will be replaced by memory within a month.

Cells That Come Back Blank

Some cells are left empty far more often than the paperwork suggests, and every empty cell turns into a verbal answer on the floor.

The first is the cycle itself. A cycle name from one washer brand means little in a department running another brand, so the record needs the phase sequence and the numbers behind the name. Without them the department cannot tell whether its own instrument cycle is gentler or harsher than what was validated, and the honest answer becomes a shrug.

The second is loading. A positioner that survives the chamber only when it lies concave side down, on a rack that keeps it out of a jet, at a stated maximum count per cycle, is not approved in any useful sense until those conditions are printed. Note also whether the item may travel with other devices, because contact with a heavier load is how coatings get scratched and how straps get caught.

The third is disassembly. “Disassemble if applicable” is the phrase buyers should refuse, because it assigns the engineering decision to the user. The record should name the parts that separate, the tool required, the parts that must not be separated, and whether the assembly is rebuilt before washing or after. Detachable components are the easy case, and a handle designed to come off for reprocessing shows why the design decision and the document decision belong together.

The fourth is the manual fallback, which has to be a method rather than a shrug. Detergent class, water temperature and quality, brushing and flushing points, rinse and drying steps, written so a new hire can follow them on the first night shift. A record that forbids the washer without supplying a manual method has moved the problem rather than solved it.

The fifth cell sits upstream, inside the factory, and hospital buyers rarely see it: the components the factory itself purchases. Foam, gel, adhesive, hook-and-loop tape, coatings, cords and sensors arrive with their own material limits, and a factory cannot approve a washer process for a material it holds no declaration for. The rule that keeps the record honest reads like this: no supplier material declaration, no washer approval. Where a component is excluded from the approval, the record should list it, so the department knows the pad is approved and the insert inside it is not.

Mixed-material assemblies deserve their own sentence. One accessory can hold two answers, and the default should be stated rather than implied: the least tolerant component governs the whole assembly, unless the components separate, in which case each gets its own row. Leaving that to the reader produces two interpretations and one ruined positioner. The best practices for documenting cleaning instructions for medical devices tend to list these fields; what they rarely do is force a verdict onto every one of them, and the verdict is the part that decides whether staff rely on the page or on each other.

When Your Washer Does Not Match the Validated Cycle

Few departments run the exact machine used for validation, so the record has to make the comparison possible. Chemistry class, temperature window, contact time, rinse water quality and drying conditions are the values that have to line up. The washer maker, the chamber size and the cycle name may differ without changing the answer. Where the local cycle is shorter, cooler, or built on a different detergent class, the department should not approve itself. The record should give the escalation path and say what the factory needs in order to reply: the local cycle parameters, the machine class, the chemistry, the load.

Document control is what keeps a record usable in year three. Revision number, effective date, the revision it replaces, and a notification commitment for the day foam, adhesive, coating, a supplier or a washer cycle changes. Spare parts should carry the same disposition as the item they replace, and the delivery papers should let the receiving team check that the current revision arrived with the goods. Where a superseded revision is still on a bench, the replacement notice is the only thing that will move it.

Ownership closes the loop. Give the record family one owner on the regulatory or quality side and one review trigger, and the printed answer replaces the verbal one. The question at the washer does not disappear because someone wrote a standard. It disappears because a technician, holding a pad with a part number on it, can turn the item over, find the line, and load the machine.
