Understanding Needle-Stick Injuries
Definition & Types
A needle-stick injury occurs when a needle or sharp medical instrument penetrates the skin of a healthcare worker, potentially exposing them to bloodborne pathogens.
Types of Sharp Injuries:
- Hypodermic needles: Most common type
- Blood collection needles: High contamination risk
- Scalpels: Deep penetration potential
- Laboratory glass: Multiple exposure sites
- IV catheter needles: Common in bedside care
Pathogen Transmission Risk
High Risk Pathogens
- Hepatitis B Virus (HBV) – 30% transmission risk
- Hepatitis C Virus (HCV) – 1.8% transmission risk
- Human Immunodeficiency Virus (HIV) – 0.3% transmission risk
Other Concerning Pathogens
- Staphylococcus aureus (including MRSA)
- Streptococcus pyogenes
- Cytomegalovirus (CMV)
- Epstein-Barr Virus (EBV)
Factors Affecting Transmission Risk
Factor | High Risk | Low Risk | Impact on Transmission |
---|---|---|---|
Needle Type | Large bore, hollow needles | Small gauge, solid needles | Larger volume of blood transfer |
Depth of Injury | Deep penetration | Superficial scratch | Deeper wounds allow more pathogen entry |
Source Patient Status | High viral load, acute infection | Low/undetectable viral load | Higher viral loads increase transmission probability |
Time to Treatment | Delayed response (>72 hours) | Immediate treatment (<4 hours) | Early intervention reduces infection risk |
Blood Visibility | Visible blood on device | No visible blood | More blood equals higher pathogen load |

- • Contact occupational health or emergency department
- • Begin incident documentation process
- • Preserve the sharp device if safely possible
Step 3: Source Assessment (Within 15 minutes)
- • Identify source patient if known
- • Review patient’s infection status and risk factors
- • Collect source patient blood samples (if consented)
- • Document circumstances of exposure
Risk Assessment & Laboratory Testing Protocol
