Infection Control Deficiencies in a Small Clinic
During a routine complaint investigation, a Maryland Board of Dental Examiners inspector visits Dr. Samuel Okafor's small clinic in Hagerstown. The inspector observes: (1) the autoclave log shows no biological spore testing for the past 90 days; (2) after steam sterilization, instruments are placed in open, uncovered trays on a counter near a sink; (3) between patients, dental handpieces are wiped with 70% isopropyl alcohol and reused; (4) two staff members have no documentation of hepatitis B vaccination or declination; (5) a sharps container is filled above the fill line and has no lid. Dr. Okafor says he follows 'common sense' and that the office has never had an infection. The inspector also notes that the practice treats 40-50 patients per week, including several with HIV and hepatitis C.

The findings map to CDC infection-control guidelines and OSHA bloodborne-pathogen rules, which the Maryland Board enforces as the standard of care:
- No spore testing for 90 days - a steam autoclave should be biologically monitored at least weekly (and every load with implants, per some protocols). Lack of monitoring means sterilization failure could go undetected.
- Open, uncovered trays near a sink - sterilized instruments must be packaged and stored in a manner that maintains sterility; open trays near a wet area risk contamination.
- Handpieces wiped with alcohol only - handpieces that contact mucosa or blood must be sterilized between patients (or use sterile/disposable barriers plus sterilization). Alcohol wipe is not sterilization.
- No HBV vaccination/declination records - OSHA requires employers to offer hepatitis B vaccination to at-risk employees and keep records of vaccination or declination.
- Overfilled sharps container without lid - sharps containers must be closable, puncture-resistant, and not overfilled.
These are not merely 'common sense'; they are regulatory requirements. The presence of HIV/HCV patients is irrelevant because standard precautions apply to all patients.
2. What corrective actions must Dr. Okafor take, and what are the potential consequences if he does not?

Dr. Okafor must immediately correct each deficiency: implement weekly biological monitoring and log results; package instruments and store them in closed cabinets; sterilize handpieces between patients; offer HBV vaccination and obtain declinations; replace sharps containers when three-quarters full and keep lids closed. He should also train staff and document the training.
The Board may require a corrective action plan, unannounced inspections, and a fine. If he fails to correct, the Board can suspend or revoke his license, or impose probation with monitoring. A pattern of noncompliance can support a finding of unprofessional conduct and endangerment.
He should also perform a look-back risk assessment for patients treated during the 90-day period without spore testing, in consultation with the local health department, to determine whether notification or testing is needed.
3. Does the presence of patients with HIV/HCV change the infection control standard? Explain.
Read the worked answer
No. The standard of care is standard precautions for every patient, regardless of known or suspected bloodborne status. Treating patients with HIV or HCV does not require extra precautions beyond standard precautions; using them as a reason for heightened precautions or refusal would be discriminatory and a violation of patient confidentiality.
The relevant question is whether the practice applies the same safe practices to all patients. If the practice is unsafe for one group, it is unsafe for all. The inspector should not single out patients with HIV/HCV; instead, the deficiency is system-wide.
Disclosure of a patient's HIV/HCV status without consent can violate Maryland confidentiality law and the patient's privacy rights.
