Sterilization Log Gap Before a Hepatitis C Patient
At a two-chair practice in Nashua, the hygienist opens the sterilization area at 7:45 a.m. The autoclave log has no entries for six weeks; the assistant says, 'We run a spore test monthly and the strips always pass.' Pouched instruments are dated only with a marker that smears; one pouch has a torn seal. The ultrasonic cleaner solution was changed last Friday, and the counter has dried blood from the previous day. The hygienist is scheduled to see a patient with chronic hepatitis C for scaling and root planing at 8:00. The office has no written infection-control manual. The dentist is on the phone in the back and says, 'Just wipe things down and get started; we've never had a problem.'
1. What should the hygienist do before the 8:00 patient is seated? Prioritize.

Stop the schedule until the sterility chain is restored. In order:
- Put on gloves and PPE; clean visible blood from the counter with detergent, then disinfect with an EPA-registered hospital disinfectant.
- Do not use the torn pouch or any pouch whose date or sterility cannot be verified. Repackage and sterilize, or use backup sterile instruments.
- Review the autoclave: run a biologic indicator (spore test) and a chemical indicator; do not release instruments from the load until the result is acceptable. If the office cannot verify sterility, reschedule the 8:00 patient.
- Change the ultrasonic solution per manufacturer and office policy; clean and dry instruments before packaging.
- Start an incident and corrective-action log.
The patient's hepatitis C status does not change the standard; standard precautions apply to everyone. The dentist's 'wipe it down' instruction is not sufficient for instruments.
2. What are the infection-control deficiencies, and what should be documented?
Read the worked answer
Deficiencies include: no sterilization log for six weeks; biologic monitoring only monthly; illegible dating; torn packaging; questionable ultrasonic solution; visible blood not cleaned; and no written infection-control manual. Document objective facts: dates, what was observed, which load and autoclave, corrective actions, and who was notified. Do not chart speculation about a patient's infection status. Record that the 8:00 appointment was delayed or rescheduled and why. The office should complete a root-cause review and retrain staff. If the Board's infection-control rule requires reporting a breach, the dentist or office should make the report; the hygienist should not assume the dentist will do it without confirming.
3. Does the patient need to be told about the lapse? Does the Board?
Read the worked answer
Tell the patient only what is clinically and ethically required. If there is a credible exposure risk-for example, a device that was not properly sterilized was used on her-the office should follow its exposure-control plan, offer testing and counseling as indicated, and document. Do not announce a general 'sterilization problem' without an exposure assessment; that can be misleading. The Board should be notified if required by law or if the office cannot correct the breach. The hygienist's first duty is to prevent exposure; after that, honesty and documentation matter more than protecting the practice's reputation.
