This is an anonymised composite of a pattern that recurs across multi-site dental groups in Canada: every office kept its own version of the sterilization log, and the group could not roll the records up. Assemble it from published requirements — RCDSO infection-control expectations, ISO 11140-1 indicator classes and CSA Z314 — and no individual clinic, no cost figure and no percentage outcome is reported here.
What Did the Logs Look Like Before Standardisation?
Every office recorded something; the fields differed. The sterilizer was identified by a room name in one office and by a serial number in another. Some offices logged the indicator lot number, others only the result. Operators signed with initials, first names or a shared account, and cycle numbers were recorded only where the machine printer produced them. Rolling four offices up for a review meant reconciling four paper conventions that never quite agreed.
Which Fields Does a Sterile Reprocessing Log Need?
The field set that resolved the differences was: a unique sterilizer ID, the cycle number, the indicator type with its lot number and expiry date, the result, the operator, and the date. A short load description helps when a recall is needed, and a field recording that the machine printout is attached closes the loop between the paper log and the machine record.
How Often Should a Biological Indicator Be Run in Ontario?
In Ontario, the RCDSO expectation is a biological indicator on each day the sterilizer is used. That daily cadence is what the log has to be able to demonstrate, and a group with several offices should be able to show the same daily pattern at every site rather than a mix of conventions.
What Happens When a Biological Indicator Fails?
A failed result is a recall event, not a note in the margin. The standard sequence is to quarantine the loads processed since the last confirmed negative result, re-run the sterilizer and the indicator, and release nothing until the failure is resolved and the resolution is documented. The log is the tool that makes the quarantine computable: without cycle numbers and dates, staff cannot identify which loads are in scope.
Practices setting up a daily routine usually start with a $12.99 BI 5-pack trial and a bench incubator, such as the 24-hour dry-block incubator, so the incubation step happens on site rather than by mail.
How Was the Template Rolled Out Across Sites?
The rollout that worked in the composite was deliberately small: one page, one field list, one entry convention for operators, and a short review of the prior seven days’ records by the site lead. Training was done against a live cycle rather than a blank form.
Each office kept its own paper stock but ordered it to one specification, so the field names printed on the form were identical everywhere. The site lead reviewed the prior seven days and treated a blank field as an exception to chase rather than a cosmetic gap.
Retention followed each practice’s own document policy. The point of the standard template was not to centralise the paper, but to make any site’s records readable without a translation step during a review.
| Problem observed | Standardised field | Basis |
|---|---|---|
| Sterilizer named by room at one site and by serial at another | Unique sterilizer ID used at every site | CSA Z314 record-keeping expectations |
| Indicator recorded by result only | Indicator type, lot number and expiry date | ISO 11140-1 indicator classes |
| Cycle could not be traced to a load | Cycle number plus a short load description | RCDSO daily monitoring and recall documentation |
| Operator signed with initials or a shared login | Named operator entry | Provincial infection-control documentation expectations |
| Paper log stored apart from the machine printout | Printout attached to the same record | CSA Z314 audit-ready record practice |

Frequently Asked Questions
What should a sterilization log record?
Sterilizer ID, cycle number, indicator type with lot number and expiry date, result, operator and date, plus a load description that supports a recall.
How often is a biological indicator run in Ontario?
The RCDSO expectation is once on each day the sterilizer is used.
What happens after a failed biological indicator?
Quarantine the loads processed back to the last confirmed negative result, re-run and document before releasing anything.
Can several offices share one log template?
Yes, provided the field names, operator convention and review cadence are identical at every site.
