The same ten sterilization compliance questions come up at almost every Canadian clinic we speak to, and they nearly all reduce to three things: how often to test, how to record the result, and how to handle a failure. This is a working answer set, not legal advice; a clinic should always confirm the current expectation with its provincial regulator for its own setting.
How Often Does a Canadian Clinic Test Its Sterilizer?
Daily for biological monitoring at the provincial level. In Ontario, for example, the expectation is a biological indicator for each sterilizer on every day it is used and for each cycle type used. Weekly is the US baseline, not the Canadian rule. Pre-vacuum units also need a daily air removal test before the first load.
What Has to Go in the Sterilizer Log?
At minimum: date, sterilizer identifier, cycle type and parameters, biological indicator lot and result, air removal result where applicable, load release decision, and the initials of the person responsible. The fields should be the same at every site in a group so results can be compared and rolled up.
What Do You Do After a Failed Biological Indicator?
Hold the load, quarantine it, and retest. Do not release the instruments until the cause is identified and a passing result is recorded. Check the air removal test, the chamber, the water supply and the load configuration first, because equipment and process faults are the common cause rather than the indicator itself.
How Long Should Records Be Kept?
Retention is set by the provincial regulator or by the clinic's own policy where no specific period is stated, and the safe practice is to keep sterilization records for at least as long as the instruments could be linked to a patient. Confirm the exact period with your regulator, then keep the log format simple enough that the period is actually met.
Do Wrapped and Unwrapped Loads Need Different Handling?
Yes. Wrapped and pouched loads need a cycle that removes air reliably, which is why a pre-vacuum Class B unit is the usual choice. Unwrapped solid instruments can run a gravity cycle. The class and the cycle should match the load, and the load list should come from the unit's manual.
What Else Trips Up a Records Review?
Missing load release initials, retests recorded in a separate book, and units changed without updating the log header. Each of those breaks traceability. A single, consistent log with a fixed field set solves all three at once, and it is the single change most clinics can make this week.
| Question | Short answer |
|---|---|
| How often to test | Daily in Canada (Ontario example); weekly is the US baseline |
| Air removal test | Daily on a pre-vacuum unit, cold chamber, before first load |
| After a failure | Hold and quarantine the load, find the cause, retest, record the pass |
| Log fields | Same fixed set at every site, including release initials |
