Sharps injury after a subcutaneous injection
You are a certificate-level health services assistant working in a community clinic. A registered nurse asks you to dispose of a sharps container that is three-quarters full. As you lift it, the lid is not fully clicked shut and a used 25-gauge needle falls out and punctures the side of your right index finger. The needle had been used 10 minutes earlier for a subcutaneous insulin injection. The patient's file shows no blood-borne virus status recorded. You are wearing gloves. The clinic's exposure protocol is kept in a folder in the treatment room, and the practice manager is off site until 2:00 pm. It is 11:15 am.
1. Outline your immediate actions in the first 15 minutes and justify the order.

Order matters because some steps reduce transmission risk and others only record it.
- Remove the glove and let the wound bleed freely under running water for several minutes; wash with soap and water. Do not scrub, suck or use bleach or alcohol - these damage tissue and do not reduce risk.
- Cover the wound with a waterproof dressing.
- Report immediately to the RN or most senior clinician on site. Do not wait for the practice manager; post-exposure prophylaxis decisions are time-critical and ideally start within hours.
- Follow the clinic's exposure protocol: identify the source patient, seek consent for blood-borne virus testing (HIV, hepatitis B, hepatitis C) and check your own hepatitis B vaccination and antibody status.
- Attend the designated emergency department or occupational health service for risk assessment and any prophylaxis, including HIV PEP if indicated and hepatitis B immunoglobulin or booster.
- Record the incident in the incident register, including time, device, source and actions taken.
Justification: bleeding and washing reduce inoculum; immediate reporting starts the time-critical prophylaxis pathway; documentation supports workers' compensation and prevention review. The container being three-quarters full and the lid not clicked are hazards to report so the container is replaced correctly.
2. Explain how the incident should be investigated afterwards and what changes would prevent recurrence.

Investigation should be a no-blame systems review, not a search for someone to blame. It should establish:
- Why a certificate-level assistant was lifting a sharps container, and whether the task was within their role and training.
- Whether the container was overfilled or assembled incorrectly, and who last closed it.
- Whether containers are checked and replaced at the fill line, not at three-quarters.
- Whether the exposure protocol folder is accessible when the manager is absent.
Prevention controls, in order of effectiveness:
- Elimination/substitution: use safety-engineered needles and point-of-care disposal.
- Engineering: secure brackets, clear fill-line marking, correct assembly checks.
- Administrative: a scheduled container check, a one-page exposure flowchart posted in the treatment room, and a named after-hours contact.
- PPE: gloves are not a substitute for safe handling.
Report the outcome to the work health and safety representative and check that the injured worker's follow-up and counselling are arranged. Document the review and communicate changes at the next staff meeting.
