Needlestick injuries remain one of the most common occupational hazards in healthcare settings. They not only cause anxiety among staff but also carry potential risks of serious blood-borne infections. Here’s a comprehensive guide for all healthcare professionals to understand, manage, and prevent these incidents effectively.

❓ What is a Needlestick Injury?

A needlestick injury occurs when a needle or sharp object punctures the skin accidentally. This is common while taking blood samples, administering injections, or disposing of sharps. The major concern is the potential transmission of blood-borne viruses (BBVs) such as:

HIV
Hepatitis B
Hepatitis C

⚠️ How High is the Risk?

The actual risk of infection is generally low, but it depends on:

✔️ Type of needle (hollow-bore needles carry higher risk)

✔️ Depth of injury

✔️ Amount of blood involved

✔️ Patient’s infection status

Approximate transmission risks:

HIV: ~0.3%
Hepatitis B: up to 30% if not vaccinated
Hepatitis C: ~1.8%

🛡️ Immediate First Aid Steps

Encourage bleeding from the site gently (don’t suck).
Wash thoroughly with soap and running water.
Do not scrub the wound.
Cover with a waterproof dressing.

📝 Reporting and Occupational Health Protocol

After first aid:

Report immediately to your line manager and occupational health.
Document the incident clearly.
Assess the source patient’s risk factors and infection status.

🧪 Can the Patient be Tested?

If conscious: Obtain informed consent before testing for HIV, HBV, HCV.
If unconscious: Testing without consent is legally complex.
- Allowed if in the patient’s best medical interests (e.g. to guide their care).
- If testing is only for the healthcare worker’s benefit, local policies vary. Senior consultation and clear documentation are essential.
- The patient must be informed later if tests are conducted while unconscious.

💉 Post-Exposure Prophylaxis (PEP) and Vaccination

1. HIV

PEP is recommended if the source is known HIV positive or high risk.
Should be started ideally within 1–2 hours, up to 72 hours maximum.
Consists of a 28-day antiretroviral therapy course.

2. Hepatitis B

If fully vaccinated with documented immunity (anti-HBs >10 mIU/mL):
- No further action needed.
If partially vaccinated or unvaccinated:
- Give Hepatitis B Immunoglobulin (HBIG) as soon as possible (preferably within 48 hours, up to 7 days).
- Complete the vaccination series to ensure long-term protection:
  - Standard schedule: 0, 1, 6 months
  - Accelerated: 0, 1, 2 months + booster at 12 months
- Check anti-HBs levels after completion to confirm immunity.

3. Hepatitis C

No effective prophylaxis is available.
Early identification and treatment if infection develops.

🔁 Follow-up Testing Schedule

Virus	Tests for exposed person
HIV	Baseline, 6 weeks, 12 weeks (or 12 weeks post-PEP).
Hepatitis B	Depends on immunity status; occupational health will guide follow-up.
Hepatitis C	Baseline, 6 weeks, 12 weeks, 24 weeks (6 months).

🔬 Liver Function Tests (LFTs) are not routinely required unless seroconversion occurs or symptoms suggest acute hepatitis.

💭 Reassuring Healthcare Staff

It’s normal to feel anxious after a needlestick injury. However, prompt reporting, appropriate management, and follow-up significantly reduce any risks. Remember:

✔️ Most injuries do not lead to infection.

✔️ Occupational health will support you throughout.

✔️ Stay updated on safe sharps disposal and prevention training to minimise future incidents.
