A four-chair clinic in Ontario lost eight weeks of sterilization records when the practice-management computer failed and the backup turned out to be three months old. Nobody had done anything wrong clinically — the sterilizers were working, indicators were reading correctly — but on paper the clinic could not demonstrate the monitoring it had actually performed. Rebuilding the record took a fortnight and changed how the clinic now keeps its log. The fix was not a better database. It was a paper and digital pair, printed from a compliance log template, with the digital system as the convenience copy rather than the only copy. The clinic also repointed every daily test at a 24-hour self-contained biological indicator, so the result that had to be recorded was always the same format.
The trigger was an IPAC review. Under Ontario expectations the records have to show a biological indicator result for each sterilizer on every day it was used — the RCDSO requires daily monitoring, not weekly. The weekly baseline is the CDC / AAMI ST79 standard in most US states. Eight missing weeks was not a paperwork annoyance; it was an unanswerable question about eight weeks of patient-facing reprocessing.
What exactly was lost, and what was recoverable?
| Record | Recoverable after the failure? | How the clinic rebuilt it |
|---|---|---|
| Daily biological indicator results | No — too old to re-run | Rebuilt as a documented gap with a forward-looking corrective action |
| Cycle log per load | Partly, from the sterilizer printer roll | Reconciled against the tray count and appointment book |
| Spore test lot numbers | Yes — purchase invoices | Matched invoices to the dates of use |
| Indicator and tape purchase history | Yes — supplier statements | Used to corroborate the monitoring volume |
Why did the backup not solve the problem?
The backup was a full system image, but the clinic logged sterilization data by hand into a form that only one person maintained. When that form lived inside a single application, "we have a backup" really meant "we have a backup of the application". A records system that cannot be produced independently of the software that holds it is not a records system, it is a single point of failure. The clinic now prints the day sheet at close and files it.
What did the clinic change afterwards?
Three things. First, a printed daily sheet that is completed in ink and filed, so the log exists on paper the moment it is written. Second, a weekly reconciliation where the digital entry is checked against the printed sheets, so drift is caught in seven days not eight weeks. Third, a named deputy who can complete and file the sheet, so the record does not stop when one person is away. None of it is expensive, and all of it is verifiable.
What should other clinics take from this?
Test your own recovery path before you need it. Ask the question: if the computer was gone tomorrow, could you produce last month’s biological indicator results? If the answer depends on a login, write the daily sheet on paper as well. The same thinking applies to consumables: keep monitoring supplies at the bench so a missing digit does not become a missing test.
Make it repeatable: print the compliance log templates, use the same page as your free log generator, and ask a compliance specialist when a result is unclear.

Frequently Asked Questions
How long should a clinic keep sterilization records?
Keep them as long as your provincial college and facility policy require, and keep a printable copy so the record survives a system failure.
Is a digital log enough on its own?
A digital log is convenient but a software failure can erase it. Many Canadian clinics keep a printed daily sheet filed by date as the authoritative copy.
What must the daily log show for each sterilizer?
A biological indicator result for each day the sterilizer is used, plus the cycle record, operator and any failed result with its corrective action.
What do you do about records that are permanently lost?
Document the gap, the cause and the corrective action, and show the rebuilt forward record. An unexplained gap is the problem; a documented one with a fix is manageable.
