A four-chair dental practice in Ontario received its college practice visit notice a few weeks ahead of time. The clinical work was never the worry. The worry was that nobody could reconstruct what had happened inside the two sterilizers over the previous months: some days logged, others blank, operator initials without a cycle number, and pouch labels gone into the waste.
Rebuilding the records took most of a weekend and exposed a problem that has nothing to do with how well a sterilizer performs. A load record is the only evidence that a specific cycle was monitored and released, and it has to stand on its own months later.
What does a college practice visit look for in sterilization records?
A reviewer starts from a cycle that has already finished and works backwards: which sterilizer ran, on what date, as which cycle of that day, with what inside the chamber, placed by whom, with what monitoring result, and what happened when a result failed. A log that misses any of those answers turns the visit into a conversation about intent rather than evidence.
The load log records the cycle; the monitoring records cover the chemical integrator and the biological indicator. Both have to point at the same load, which is why our breakdown of the sterilization record gaps that recur in Canadian dental offices keeps returning to the same missing column.
Which fields should a load record contain?
The original log had a date column and a signature column, which shows someone was present and proves nothing about the load. The rebuilt log added the fields below, each mapped to a question the reviewer will ask.
| Field | Question it answers | Source |
|---|---|---|
| Sterilizer identifier | Which unit ran this cycle? | Unit label or asset tag |
| Date and cycle number | When, and in what order that day? | Cycle printout or manual entry |
| Load contents | What was inside the chamber? | Cassette list or pouch labels |
| Operator | Who placed and released it? | Initials matched to a staff list |
| Monitoring result | Did the indicators pass? | Integrator and biological indicator result |
| Failure action | What was done when a result failed? | Quarantine note, retest, release entry |
How often does Ontario expect a biological indicator?
In Ontario, the RCDSO requires a biological indicator for each sterilizer on every day it is used. The weekly baseline is the CDC / AAMI ST79 standard in most US states, and it is the rhythm many teams carry over from material written for that market. In a Canadian clinic the daily rule is the one the log has to show, because a missing day cannot be explained by a weekly schedule.
Here the gap came from a rotating monitoring roster that left unmonitored days whenever the assigned staff member was away. The fix was a monitoring column on the same page as the load log, completed at the start of the day rather than the end, so a blank cell is visible to the whole team.
How do you rebuild records that were never written down?
Reconstruction has a hard limit: you can only assert what you can support. Where cycle printouts, pouch labels or indicator packaging survived, an entry can be rebuilt from those artefacts and marked as reconstructed. Where nothing survived, the honest entry is a documented gap with a corrective action attached. Inventing a plausible date to fill a box converts a record-keeping problem into a trust problem.
What happens in the log when a monitoring result fails?
The load does not get released. The failure is recorded on the same row as the cycle, the load is quarantined, the instruments are reprocessed, and the retest result is written against the original entry rather than on a fresh page. A reviewer who sees a retest that cannot be connected to the failed load will still ask how those instruments were handled.

Frequently Asked Questions
How long should autoclave load records be kept?
Retention periods are set provincially and they do change, so confirm the current period with your regulatory college, write it on the log header, and store records so any date can be pulled in minutes rather than days. A record you cannot produce on request protects nothing.
Is the date enough, or does the log need a cycle number?
A date is not enough on any day with more than one cycle, because a monitoring result has to attach to one load. Numbering the cycles and carrying that number onto the indicator record keeps the two documents connected.
Can a sterilizer go back into service after a failed biological indicator?
Not on the strength of the failed load itself. The affected load is held, the instruments are reprocessed, and the unit is retested before further loads are released. The retest result belongs on the same row as the failure, so the disposition of that load stays visible.
Does a chemical indicator replace the biological indicator?
No. A chemical integrator shows that cycle conditions were reached, while a biological indicator shows whether spores were actually killed. In Ontario, the RCDSO requires a biological indicator for each sterilizer on every day it is used, so the two tests answer different questions.
