Connect instrument sets, processing records, release decisions and patient use, with suitable identification, packaging and recall arrangements.
Medical equipment RFQ checklist (TXT)
A traceability system should connect an instrument set to cleaning, packing, sterilisation, release, storage and use. When a concern arises, the hospital needs to identify the affected items and patients through a documented investigation and recall procedure.
This article focuses on instrument and batch traceability across the CSSD workflow. Process validation is a related but separate responsibility addressed in the linked guide. Related reading: Sterilisation validation and record keeping: what you have to be able to prove.
That is the design brief. Everything below follows from it. Layout and flow are treated separately on this site, as is steriliser sizing; this is about the record.
Choose the traceability level from risk, workload and clinical requirements. Set-level tracking is a practical starting point for many services, but it must accommodate changed set contents and individually controlled instruments where required.
Individual-instrument tracking can support loan sets, high-value devices or limited-use items. Compare those benefits with marking compatibility, staff work and system support; the decision should follow the service’s risk and traceability needs.
Select identification that is compatible with the instrument material, cleaning and sterilisation process. A mark that survives processing can still be unsuitable if it damages the instrument or creates a cleaning problem.
Evaluate identification and scanning under representative clean packing-bench conditions, including gloves and the actual lighting. Wet or incompletely processed items should follow the department’s procedure rather than being treated as normal packing conditions.
The load is the atomic unit of a sterilisation record. A load number that identifies steriliser, cycle and date is what links a pack to everything else.
| Element | Why it is in the record |
|---|---|
| Steriliser identity | A recall is often steriliser specific, not date specific |
| Cycle number and date | The unique key everything else hangs from |
| Cycle type | A porous load cycle and an instrument cycle prove different things |
| Contents list | What has to be recalled, and what was exposed to a failed cycle |
| Physical parameter record | The printout or electronic trace of temperature, pressure and time through the cycle |
| Chemical indicator result | Read and recorded at the time, by a named person |
| Biological indicator result | Where used, with the incubation result recorded when it becomes available |
| Operator identity | Someone has to be answerable for the release decision |
| Release decision | Explicitly recorded as released or quarantined, not implied by the pack being on a shelf |
Plan continuity for printer or electronic-record failure and retain readable records for the required period. Keep approved consumables and verified backups available; an unreadable or missing physical record must be handled under the load-release procedure.
Indicators are routinely misread as a pass mark for sterility. They are not, and knowing what each one proves is what makes a batch record defensible.
Perform vacuum leak and other equipment checks at the required intervals and investigate failures under the approved procedure. Wet packs and process failures can have multiple causes; a load pattern alone does not identify a leak.
Use suitable sterile-barrier systems and validate or qualify sealing processes as required by the applicable ISO 11607 scope and packaging instructions. Set checks, parameters and acceptance limits for the actual sealer and material rather than assuming one daily test proves all seals.
Set storage and shelf-life policy from the sterile-barrier system, manufacturer instructions, handling conditions and applicable requirements. Time-related and event-related approaches both require intact packaging and controlled storage; a date never compensates for a wet, damaged or opened pack.
Provide storage that protects packs from moisture, damage and contamination, with appropriate environmental monitoring and handling. Closed cabinets such as an appropriately configured SKH091 may help, but cabinet type alone does not justify event-related shelf life.
Link the set/load to the patient at the point of use through the approved clinical record, whether by label or a validated electronic workflow. Assign responsibility and include contingencies for unreadable labels or system downtime.
Make the link practical for the clinical team and audit both backward and forward tracing. Select a representative sample under the quality plan rather than treating a fixed ten-record check as complete validation.
Paper and electronic systems can both support traceability if they are complete, accessible and tested. Compare retrieval time, record volume, error controls and backup arrangements, including how patients associated with one load can be found.
Tracking software may be worthwhile where volume, instrument control or retrieval needs justify it. Quote the hardware, labels, licences, data ownership, export, backups and support together. Plan continued access to records if a subscription or supplier relationship ends.
