Sterilization Logs and a Patient with Active TB
A New Jersey dental office has used the same autoclave for three years. The office cannot produce biological spore test results for the last six weeks; the assistant says the team relies on chemical indicator strips and that the autoclave 'looks fine.' Packaged instruments are stored in closed cabinets. The autoclave log has no dates for the missing period. Separately, a patient with confirmed active pulmonary tuberculosis is scheduled for a routine prophylaxis tomorrow. The front desk asks whether to keep the appointment. The office has no negative-pressure room and no N95 fit-tested staff. The dentist wants to know what sterilization monitoring is required and whether the tuberculosis patient can be treated and reported.
1. What sterilization monitoring deficiencies exist, and what corrective actions should the office take?
Read the worked answer
The office is not meeting sterilization monitoring standards. Chemical indicator strips show that the package was exposed to the sterilization process, but they do not prove that sterilization occurred. Biological spore testing with a commercial indicator should be performed at least weekly for each autoclave, and results should be logged with date, autoclave identifier, result, and corrective action. Six weeks of missing results is a gap. The autoclave should be tested now; if a spore test is positive, the autoclave should be removed from service, the manufacturer's instructions followed, instruments reprocessed, and patients potentially exposed assessed under the office's infection-control policy. The office should also review load records, packaging, and storage.
2. Can the patient with confirmed active pulmonary tuberculosis be treated for routine prophylaxis in this office? What reporting obligations apply?
Read the worked answer
For the patient with confirmed active pulmonary tuberculosis, routine prophylaxis should be deferred until the patient's physician documents that the patient is no longer infectious. Active TB is transmitted by airborne route, and a dental office without negative-pressure ventilation and fit-tested N95 respirators should not perform elective care. If urgent dental care is needed, refer to a facility with appropriate airborne infection isolation precautions. The dentist should not simply treat the patient in the regular operatory. Confirmed or suspected tuberculosis is reportable to the local health department in New Jersey; the dentist should report per local health department instructions and document the referral and communication.
3. What documentation and staff training should follow these events?
Read the worked answer
The office should document the sterilization gap, the corrective actions, and any patient notifications. It should maintain autoclave logs, spore test results, and equipment maintenance records. For the TB patient, document the deferral, the physician contact, and the public health report. Staff should be retrained on CDC and OSHA infection control, and the office should have a written exposure-control plan.
