A 120-bed long-term care home reprocessed a small but steady volume of reusable instruments across two sterilizers on different floors. Rework, meaning loads that had to be reprocessed because a monitoring result was missing or ambiguous, had crept up to the point where nursing staff were regularly chasing instruments between units. The home audited its practice over eight weeks and rebuilt the routine around separation and documentation.
What was driving the rework?
The audit found the issue was not a failing sterilizer. It was that two units ran similar cycles with different habits, and the monitoring records lived in two different places. When a resident-care nurse needed to confirm a load, the evidence was often incomplete, and a cautious team reprocessed rather than argue the point.
Three specific faults recurred: indicators held for one unit were incubated with another unit's batch, log entries named the floor rather than the sterilizer, and some results were recorded without a read time. None of those is a machine problem, but together they made the record unusable.
What did the home change?
Monitoring was centralised onto one incubation routine using a 15-well precision dry-block incubator and a 24-hour rapid readout biological indicator, 50-pack, so every unit's indicators incubated together under one read time. Log pages were replaced with a single shared form that named the sterilizer, the cycle, the load and the reader for every result.
The home also stopped mixing load types on one cycle where the manufacturer's instructions did not support it, and set a written rule that no load leaves the room without its matching log line.
What were the results over the following quarter?
Rework dropped to near zero because staff could find a complete record for every load. The time spent chasing instruments between floors fell with it. The single most useful change, according to the supervisor, was naming the sterilizer rather than the floor, which removed the ambiguity that had driven cautious reprocessing.
| Fault found | Change made | Effect |
|---|---|---|
| Indicators batched by floor | One shared incubation routine | Consistent read time |
| Log named the floor | Log names the sterilizer | Records became traceable |
| No read time recorded | Read time is a required field | Results became auditable |
| Load types mixed | Separate incompatible loads | Fewer ambiguous results |
What did the home learn?
Rework is usually a records problem before it is an equipment problem. When staff cannot confirm a load quickly, they reprocess defensively, and the cost shows up as time rather than as a failed test. Closing the documentation gap removed the reason to reprocess.
The home now runs a monthly spot check of ten log lines against the incubator batch, and keeps a BI 5-pack trial (CA $12.99, shipping included) on hand for staff training so new hires practise the routine before they are responsible for a live load.

Round Out Your Sterilization Setup
A biological indicator is one link in the chain — these are the pieces it works with:
- Sterilization pouches — Class 4 dual-indicator, 200-pack — the packaging the indicator rides inside
- Autoclave indicator tape — 3-roll set — the external chemical indicator on every pack
- Class 5 chemical integrators — 100-pack — the in-pack check that pairs with your biological indicator
- Sterilization roll — 50 m pre-cut sheets for larger instruments
- Constant-heat pouch sealer — 200 °C, 12 mm seal — for consistent pouch closures
Which format does your sterilizer actually need?
Match the readout time to how fast you need the result: a 24-hour self-contained indicator works in any gravity or pre-vacuum cycle with a standard incubator, while a 3-hour fluorescence tube needs the matching reader. Running one cycle type per day, the 25-pack covers a month; busier clinics move to the 100-pack and cut the per-test cost.
How much do spore tests cost in Canada?
Published pricing runs $3.40 per test on the 25-pack down to $2.99 on the 100-pack — no distributor quote, no account needed.

Frequently Asked Questions
Why do care homes reprocess loads that may be fine?
Usually because the monitoring record is incomplete or names the wrong unit. Staff cannot confirm the load quickly, so they reprocess defensively to be safe.
Should the sterilization log name the unit or the floor?
Name the sterilizer identifier. A floor name is ambiguous when more than one unit is in service, and ambiguity is what forces unnecessary reprocessing.
How can a care home reduce sterilization rework?
Centralise incubation under one read time, keep a single log form that records the unit and cycle, and require a log line before any load leaves the room.
How often should the log be checked?
A monthly spot check of around ten entries against the incubator batch catches drift before it becomes a rework problem.
