Needlestick From a Source Patient With Unknown Status, Friday at 4:40 p.m.
At 4:40 p.m. on a Friday, a medical assistant is performing a venipuncture on a 34-year-old new patient. No outside laboratory results are in the chart, and while the tubes are being labeled the patient mentions he was incarcerated until four months ago. As the MA withdraws the butterfly needle, the patient's arm jerks and the needle, which was never recapped, punctures the pad of her left thumb through a nitrile glove as she angles it toward the sharps container. The puncture bleeds. The physician is in an exam room with another patient and is not expected to be free for 15 minutes. The practice has a written exposure control plan and post-exposure starter packs in the laboratory. The office closes at 5:00 p.m. and the practice manager has already left for the day.
1. What are your first actions in the first 15 to 30 minutes, and why can't this wait until the physician finishes the current visit?

Immediate care: wash the wound with soap and running water, allow it to bleed freely briefly, and do not scrub, squeeze, or apply bleach or caustic agents - those practices increase tissue damage and have not been shown to reduce transmission. If any body fluid had contacted mucous membranes, flush with water or saline for 15 minutes.
Why it can't wait: HIV post-exposure prophylaxis is most effective the sooner it is started, with guidelines favoring initiation within hours. Fifteen minutes of delay does not doom the outcome, but 'wait until she's done' can become an hour, then 'we'll handle it Monday,' and by then the window for optimal PEP has narrowed and the source patient is gone. An exposure is an emergency in the exposure control plan; the physician should be interrupted.
Sequence: report the exposure to the physician now; open the post-exposure starter pack per the written plan; determine the source patient's status and whether the source can be tested; arrange same-day evaluation at occupational health or the emergency department for baseline serologies and a PEP decision. Document the time of exposure and the time of each notification.
2. How do you approach the source patient about testing, what do you do if he refuses, and what may you not tell him?
Read the worked answer
Ask, don't demand. Explain in plain terms that an exposure occurred and that knowing his HIV, hepatitis B, and hepatitis C status protects his own health as well - results will be shared with him, and he may receive needed care he did not know he required. Request written consent for the testing the practice's protocol specifies.
What you must not disclose: anything about the exposed employee's health status, and no speculation about her risk. Disclosing the worker's HIV status or implying it is a way of pressuring the patient and is a privacy violation in both directions.
If he refuses: document the refusal in his own words, do not argue or threaten, and escalate to the physician and practice manager. Many jurisdictions permit source testing in occupational exposure situations without consent, or permit disclosure of only the minimum necessary results (for example, a positive HIV result) to the exposed worker. Because this is state-specific, the decision belongs to the physician and administrator, not to the MA at the front desk.
Also: the source patient's results go in his record; the employee's evaluation goes in a confidential occupational health file, never in the general personnel file.
3. What records and follow-up does this event generate, and what belongs on the OSHA sharps injury log?
Read the worked answer
Sharps injury log (required for sharps injuries; must protect confidentiality): type and brand of device, department where it occurred, and an explanation of how the injury happened - for example, 'butterfly needle, exam room 2, patient movement during withdrawal; no safety device engaged; puncture through glove to thumb pad.' This is the document that drives device evaluation, so accuracy matters more than blame.
OSHA 300 log: a needlestick injury is recordable when it results in medical treatment beyond first aid, which post-exposure prophylaxis and follow-up serologies typically constitute. Record it within the required timeframe; do not record the employee's name on the public portion.
Separate confidential file: exposure incident report, source patient consent or refusal, baseline and follow-up serologies at the intervals the protocol specifies (commonly 6 weeks, 3 months, 6 months), hepatitis B vaccination status and titer, and the PEP decision and rationale.
Other: workers' compensation paperwork, and a review of why the safety device did not prevent the injury - a retractable butterfly would likely have prevented it, which is exactly the point of the log.
