A Vancouver dental practice failed a sterilization review when a reviewer could not match three days of loads to their indicator results. The failure mattered because it stopped elective treatment while the practice rebuilt its records. This review walks through what the reviewer asked for, what the practice had to pause, what it changed and how it measured the cost.
What triggered the review?
The practice ran four chairs and two benchtop pre-vacuum sterilizers. A routine review asked for one specific day's load: the cycle printout, the internal indicator result and that day's biological indicator record. Staff produced the printout and the indicator result but could not find the biological indicator entry, because results were written on a wall calendar that had since been replaced. The reviewer expanded the request to three weeks, and the gaps multiplied.
What did the practice have to pause?
- Elective treatment stopped on the chairs served by the affected sterilizer while records were reconstructed.
- Instrument reprocessing was moved to a single unit with a lower throughput, slowing tray turnaround.
- Staff hours shifted from chairside work to sorting, matching and re-filing cycle strips.
- A part-time administrator was brought in to rebuild the log from printouts and purchase records.
How did the practice measure the cost?
The practice did not reduce the cost of the failure to a single invoice, because most of it never appeared on one. The cost showed up as chair capacity that could not be booked, staff hours that went to filing rather than patients, and a slower reprocessing loop that pushed appointments later in the day. Those are real costs, but they are costs of time and capacity rather than of a single purchase. The practice tracked them as days of reduced chair availability and as staff hours reassigned, not as a dollar figure.
What records did the practice rebuild and keep?
| 记录类型 | 用途 |
|---|---|
| Load log by unit and load number | Traces each load to its cycle strip and indicator |
| Daily biological indicator log | One entry per use day, with the operator's initials |
| Air-removal test sheet | Records the first-cycle Bowie-Dick result each use day |
| Corrective action sheet | Documents any failed test and the retest that closed it |
What did the practice change in the workflow?
Records moved from a wall calendar to a load log keyed to the sterilizer's serial number and the load number. Every load carried its number from the printout to the internal indicator to the day's biological indicator, so a reviewer could follow one load end to end. The practice added a five-minute end-of-day check: the last person in the room confirmed that the day's log was complete before leaving. The two sterilizers went onto the same daily air-removal and biological indicator schedule so neither could fall behind.
What did the recheck show, and what are the reusable lessons?
On recheck the practice produced a complete day's load within minutes, which is the test the first review had failed. Three lessons carried forward: key every record to the unit serial number, give each load a number and carry it through every indicator, and never let a testing result live somewhere it can be thrown away. The pause was the expensive part, and almost all of it traced back to records that existed but could not be found.
What did the practice do with the instruments during the pause?
Instruments that could not be matched to a documented cycle were reprocessed from scratch before any patient use, and the practice kept a separate list of the trays involved. Nothing was released on the assumption that a missing record meant the cycle had passed. Treating the gap as a recall rather than an inconvenience was the decision that defined the recovery, even though it added work while the chairs were already quiet.
How did the practice keep the pause from repeating?
It made the end-of-day log check part of closing the room rather than an extra task. Staff signed the day's log before leaving, and the practice kept a spare month of log sheets at the steriliser so a shortage of forms never became a reason to skip an entry.

Frequently Asked Questions
Why did the practice have to pause treatment?
Records could not be matched to loads, so the practice could not show the affected sterilizer's cycles were monitored. It paused elective work while records were rebuilt.
How was the cost of the failure measured?
In chair capacity and staff hours, not a single dollar figure. The practice tracked reduced chair availability and reassigned filing hours.
What is the fastest fix after a failed audit?
Key records to the unit serial number and a load number, then carry that number through every indicator so any load can be traced end to end.
