The Autoclave Log and the Glutaraldehyde Tray
The Seaside Community Clinic has one autoclave. The infection-control log shows biological spore tests on March 3 and March 24, with nothing since. The autoclave printer is broken. A new dental assistant, Kelsey, has been "cold sterilizing" metal scalers and curettes in a glutaraldehyde tray because the autoclave cycle takes 45 minutes and the clinic is short-staffed. She uses the same tray for contaminated and clean instruments and tops off the solution weekly. The hygienist, Dana, notices visible rust on a scaler and a crack in the ultrasonic cleaner lid. The clinic's written infection-control plan was last updated in 2019 and does not mention spore testing. The clinic serves 60 patients per week, many with HIV or hepatitis C. Dana is asked to sign off on the monthly OSHA log.
1. Identify the infection-control violations and explain why each is a problem.
Read the worked answer
At least six problems are present:
- Spore testing is not being performed at the required interval. Biological monitoring is the accepted check on sterilization effectiveness; a log with no recent results means the clinic cannot show the autoclave is working.
- Critical instruments are being "cold sterilized." Scalers and curettes penetrate tissue and contact blood; they must be cleaned and heat sterilized. A glutaraldehyde tray used as a shortcut is not an acceptable substitute for a validated autoclave cycle.
- Clean and contaminated instruments share a tray. This cross-contaminates instruments that are supposed to be ready for use.
- Topping off the glutaraldehyde does not maintain the required concentration; the solution must be discarded and replaced according to the manufacturer's instructions and tested for efficacy.
- Rusted instruments and a cracked ultrasonic lid cannot be reliably cleaned or sterilized; they should be removed from service.
- The written infection-control plan is outdated and incomplete. The clinic lacks a current, enforceable protocol for monitoring, instrument processing, and staff training.
2. What immediate corrective actions should Dana take before seeing the next patient?
Read the worked answer
Dana should stop the use of the glutaraldehyde tray for critical instruments and remove the rusted scaler and cracked ultrasonic lid from service. All instruments that were "cold sterilized" should be considered contaminated and reprocessed through a functioning autoclave before use. The autoclave should be biologically monitored immediately; until a passing result is documented, the clinic should use a backup sterilizer or single-use alternatives, or refer patients elsewhere for procedures requiring sterile instruments.
She should separate dirty and clean areas, discard and remix the glutaraldehyde per the manufacturer, and document the corrective actions. The written infection-control plan should be updated to include spore-testing frequency, instrument-processing steps, and staff training. Dana should not sign an OSHA log that she knows is inaccurate. If a breach may have exposed patients, the clinic should follow its exposure-control and risk-management process and involve the medical director.
3. Does this situation require a report to the Oregon Board of Dentistry, and what internal follow-up is needed?
Read the worked answer
A report is not automatically required for every infection-control lapse, but the Board expects licensees to practice safely and not conceal conduct that creates a risk to patients. Dana should escalate internally first: notify the clinic director or compliance officer in writing, document the violations and corrections, and ensure staff are retrained. If the clinic refuses to correct the practice, or if patients were put at risk and the conduct continues, a Board report becomes the safer professional choice.
Dana should also avoid signing any record she believes is false. The clinic should review whether patients need notification or testing under its exposure-control policy, and it should document the autoclave repair and negative/positive spore results. The focus is patient safety and a reliable system, not just a single instrument tray.
