Needlestick, a Silent Source Patient, and a Broken Exposure Plan
Ana M., RDH, has worked six weeks at a federally qualified health center in Prince George's County. She is scaling tooth #30 when the patient jerks; the needle on the anesthetic syringe she is holding - the in-room sharps container has been full since morning and is taped over - punctures her left index finger through a double glove and draws blood. The source patient, a 41-year-old with a history of incarceration, says 'I don't want any tests' and refuses HIV and hepatitis testing. Ana's hepatitis B vaccination series was completed in 2019, but she has never had a titer checked. She is 24 weeks pregnant. Later she sees staff emptying full sharps containers into a larger container by hand in the utility room and finds that the center's exposure control plan was last updated in 2016 and contains no post-exposure procedure.
1. Set out Ana's immediate post-exposure steps, with timing, and the evaluation she needs for HIV, hepatitis B, and hepatitis C.

Immediately. Wash the puncture with soap and running water; do not squeeze or milk the wound; flush mucous membranes if splashed. Report the exposure at once to the designated supervisor even though the written plan is silent - the employer's duty to provide post-exposure evaluation does not depend on the plan being good.
Timing matters. HIV post-exposure prophylaxis works best started as soon as possible and no later than a few hours after exposure; a 28-day three-drug regimen is standard for a high-risk percutaneous exposure. Do not wait for the source patient's consent to begin the risk assessment. Hepatitis B: her vaccination series is documented but her response was never checked - draw HBsAg, anti-HBs, and anti-HBc on Ana; if she is a non-responder, HBIG plus a vaccine booster is indicated. Hepatitis C: baseline anti-HCV and RNA with follow-up testing at the intervals the protocol specifies; there is no prophylaxis, but early treatment cures. Pregnancy does not contraindicate HIV PEP, though the regimen should be chosen with obstetric input.
Who evaluates. A qualified healthcare professional provides the confidential evaluation and follow-up, and the employer pays for it. Ana should also have baseline HIV and pregnancy-appropriate labs and be told the window-period implications for her own testing.
Do not use the source patient's refusal as a reason to skip PEP, and do not test leftover blood from the procedure without authorization.
2. The source patient refuses testing. What can the center do, and how should the refusal be handled?
Read the worked answer
Counsel first, do not coerce. The exposure-control process is to explain why testing matters - the result determines whether Ana takes 28 days of antiretrovirals with real side effects - and to offer confidential, consent-based testing with linkage to care. Many refusals reverse once the purpose is explained and confidentiality is assured, particularly if the patient fears the result reaching his family or employer.
If he still refuses. Treat the source as unknown status and proceed with PEP based on exposure risk: hollow-bore needle, visible blood, deep injury, high source viral load unknown. Document the counseling, the refusal, and the date. Follow the center's or state health department's procedure for source evaluation in occupational exposure, which may provide a route for testing without the patient's consent in limited circumstances; that decision belongs to the exposure-control clinician and the health department, not the hygienist, and the patient must not be told otherwise.
Confidentiality cuts both ways. Ana is not entitled to the source patient's identity-linked results beyond what the exposure protocol permits; she is entitled to know her own status and what to do. The source patient's record and Ana's medical record are separate, and Ana's record stays confidential and is not filed in her personnel file.
Do not discuss the patient's history of incarceration as if it were a diagnosis, and do not let a co-worker's speculation about his status drive the clinical decision.
3. Identify the employer's violations and the records and corrective actions that should follow. What protections does Ana have?

Violations visible in the scenario.
- Sharps containers were overfilled and taped shut, forcing a contaminated needle to be carried; containers must be replaced when about three-quarters full, closable, and never emptied by hand into a second container.
- Staff are hand-transferring sharps, which is prohibited handling practice.
- The exposure control plan is nine years stale with no post-exposure procedure; it must be reviewed at least annually, reflect current technology, and be accessible to employees.
- Ana's hepatitis B vaccination response was never verified, and no titer was on file.
Records. A sharps injury log entry (type and brand of device, department, explanation) maintained so it protects the injured worker's confidentiality; a confidential medical record separate from the personnel file; documentation of the source evaluation and of Ana's follow-up; documentation that the employer paid for evaluation and prophylaxis.
Corrective actions. Replace and relocate containers so a container is within reach in every operatory; retrain all staff; rewrite the plan with a named post-exposure clinician and 24-hour contact; audit compliance monthly; use safer sharp devices.
Protections. Ana is entitled to a safe workplace, to post-exposure prophylaxis at the employer's expense, to confidentiality of her medical information, and to raise the hazard without retaliation. Maryland's occupational safety enforcement and the whistleblower protections for healthcare workers apply; if the hazards persist after she reports them in writing, she has a reporting decision and should document every escalation.
