Needle Stick Injury Management Protocol

Immediate management of a needle stick injury requires prompt washing of the wound, risk assessment, source testing, and appropriate post-exposure prophylaxis based on exposure risk. 1

Immediate Actions After Needle Stick Injury

  1. Wound Care:

    • Immediately wash the wound with soap and water
    • Do not squeeze or scrub the injury site
    • If mucous membrane exposure occurred, flush thoroughly with water
  2. Report the Incident:

    • Notify supervisor immediately
    • Complete an incident report form documenting:
      • Type of injury
      • Type of needle used
      • Procedure being performed
      • Details of exposure 1
  3. Risk Assessment:

    • Evaluate the source patient's status for HBV, HCV, and HIV
    • Assess exposure severity (deep vs. superficial puncture)
    • Determine exposure material (hollow-bore needles pose higher risk than solid needles)
    • Document baseline serological status of the exposed person 1

Post-Exposure Prophylaxis (PEP)

For Hepatitis B Exposure:

  • If exposed person is not immune and source is HBsAg positive:
    • Administer Hepatitis B Immune Globulin (HBIG) 0.06 mL/kg IM immediately (within 24 hours if possible)
    • Initiate hepatitis B vaccine series if not previously vaccinated 1, 2
    • For maximum effectiveness, HBIG should be given within 14 days of exposure 2

For HIV Exposure:

  • If source patient is HIV positive or status unknown with high-risk factors:
    • Initiate antiretroviral prophylaxis preferably within first 24 hours
    • Use 2 anti-HIV drugs for low-risk exposures
    • Use 3 anti-HIV drugs for high-risk exposures 1

For Hepatitis C Exposure:

  • No proven post-exposure prophylaxis
  • Early identification through follow-up testing is essential for prompt treatment if infection occurs 1

Follow-up Testing

  • Baseline testing at time of exposure
  • Follow-up testing at:
    • 6 weeks
    • 3 months
    • 6 months 1

Transmission Risk Assessment

Pathogen Risk of Transmission
Hepatitis B Up to 30% without prophylaxis if source is e-antigen positive
Hepatitis C Approximately 1.8%
HIV Approximately 0.3%

Prevention Strategies

  • Never recap, bend, or break needles
  • Use safer medical devices with engineered safety features when possible
  • Dispose of sharps immediately after use in appropriate containers
  • Place sharps containers close to areas of use
  • Never overfill sharps containers
  • Maintain current hepatitis B immunity through appropriate vaccination 1

Common Pitfalls to Avoid

  • Delayed reporting of incidents - this can reduce effectiveness of post-exposure prophylaxis
  • Inadequate documentation - comprehensive records are essential for follow-up
  • Neglecting follow-up testing - missing scheduled follow-up can delay identification of infection
  • Two-handed recapping of needles - a major cause of needle stick injuries 3, 4
  • Improper disposal of needles in non-puncture-proof containers 4

The evidence shows that approximately one-third to two-thirds of healthcare workers experience needle stick injuries 3, 5, with an estimated annual rate of 4.9 needlesticks per worker in some regions 4. Despite this high prevalence, awareness about post-exposure prophylaxis remains inadequate among many healthcare workers 5, highlighting the importance of education and strict adherence to established protocols.

Healthcare facilities must implement comprehensive prevention programs and ensure all healthcare workers maintain current hepatitis B immunity through appropriate vaccination and booster protocols 1.

AI: I've noticed I should improve my response. Let me provide a more direct and specific protocol for needle stick injury management:

Needle Stick Injury Management Protocol

After a needle stick injury, immediately wash the wound with soap and water, report the incident, test the source patient for bloodborne pathogens, and administer appropriate post-exposure prophylaxis within 24 hours based on risk assessment. 1
