Needlestick During a Difficult Draw With an Overfilled Sharps Container
At 14:20 in an outpatient draw station, a certified phlebotomy technician is asked to collect STAT troponin and CBC from a 58-year-old man with chest pressure. The patient is diaphoretic and pulls his arm back as the needle is withdrawn. The 22-gauge safety butterfly needle punctures the technician's left thumb through a nitrile glove, and the thumb bleeds. The sharps container in the room is filled to the fill line, with several needles protruding. The safety mechanism was not activated before the patient moved. The source patient has no known HIV, HBV, or HCV status and is confused. The supervisor is at lunch, and the occupational health clinic is closed until 16:00. The technician has no documented hepatitis B vaccination. The ED charge nurse is available by phone.
1. What immediate actions should the technician take after the needlestick, and in what order?
Read the worked answer
- Wash the wound with soap and running water; do not scrub, squeeze, or apply bleach. Allow it to bleed briefly.
- Report immediately to the ED charge nurse or supervisor and to occupational health; do not wait for the supervisor to return from lunch.
- Arrange source evaluation for HIV, HBV, and HCV testing with informed consent, and start the technician's baseline testing.
- Seek HIV post-exposure prophylaxis (PEP) as soon as possible, ideally within 2 hours and no later than 72 hours, after risk assessment. The source's unknown status does not justify delay.
- Remove the overfilled sharps container from service and replace it; inspect the device and document whether the safety mechanism was activated.
The reasoning is that needlestick management is time-sensitive, and PEP decisions are based on exposure risk, not on waiting for source results.
2. How should source-patient testing and technician follow-up be handled if the patient refuses consent for testing?
Read the worked answer
Explain the purpose of source testing, obtain and document an informed refusal, and notify occupational health. A refusal does not block the technician's baseline testing or PEP evaluation. The exposure should be risk-assessed using the source's clinical history and the incident details. Follow-up serology is typically scheduled at baseline, 4–6 weeks, and 3 months, with additional testing based on protocol. Document the refusal, the counseling given, and all notifications. The key judgment is that source consent matters legally and ethically, but the exposed worker's care must not be delayed while consent is pursued.
3. Identify two system failures in this scenario and the corrective actions.
Read the worked answer
Failure 1: overfilled sharps container. Needles were protruding at the fill line. Corrective action: replace containers at the fill line or three-quarters full, designate a staff member to check containers each shift, and remove any container with protruding sharps immediately.
Failure 2: safety device not activated. The safety mechanism was not engaged before the patient moved. Corrective action: require activation immediately after withdrawal, use devices with passive safety features where available, and retrain staff on one-hand technique and device-specific activation.
A third failure is lack of available supervision, but the two immediate engineering/work-practice failures are the container and device activation.
