Management of Needlestick Injuries

Immediate Actions

• The American College of Occupational and Environmental Medicine recommends washing the puncture site with soap and water immediately without squeezing or applying pressure to increase bleeding 1, 2, 3
• If blood splashed into eyes, nose, or mouth, flush the area immediately with clean water or saline 1, 2
• Do not recap, bend, or break the needle after injury 4, 2
• Document the exact time of injury immediately—timing is critical for determining PEP eligibility 1, 2

Reporting and Medical Evaluation

• Report to your supervisor immediately and document the date, time, type of device involved, depth of injury, source patient details, and condition of your skin (intact vs. non-intact) 1, 2, 3
• Seek emergency medical evaluation within 1 hour—this is essential because PEP must be started as soon as possible, ideally within the first hour and absolutely within 72 hours 1, 2, 3

HIV Post-Exposure Prophylaxis

• Start PEP immediately if presentation is within 72 hours, even before confirming the source's HIV status for substantial exposures 1, 2, 3
• The risk of HIV transmission from a percutaneous needlestick with HIV-infected blood is approximately 0.36% (3-4 per 1,000 exposures) 1, 2, 3
• PEP reduces this risk by approximately 81% when started promptly 1, 2, 3
• Effectiveness drops dramatically after 72 hours, so time is critical 1, 2, 3
• The preferred PEP regimen is bictegravir/emtricitabine/tenofovir alafenamide (single tablet once daily) for 28 days 1, 2, 3
• Completing the full 28-day course is essential—stopping early eliminates protection 1, 2, 3

Hepatitis B Management

• If you are unvaccinated or incompletely vaccinated and the source is HBsAg-positive, administer Hepatitis B Immune Globulin (HBIG) 0.06 mL/kg intramuscularly as soon as possible, ideally within 24 hours 2
• Begin the hepatitis B vaccine series immediately 1, 2
• The risk of HBV transmission without prophylaxis can exceed 30% after exposure to HBeAg-positive blood 5, 2, 3

Hepatitis C Management

• No post-exposure prophylaxis exists for hepatitis C—early identification through testing is the primary approach 1, 2, 3
• The risk of HCV transmission is approximately 1.8% (range 0-7%) per percutaneous exposure 1, 2

Follow-Up Testing

• For HIV, testing at 6 weeks, 3 months, and 6 months post-exposure 3
• For Hepatitis C, baseline anti-HCV and ALT testing, and follow-up testing at 4-6 weeks and 4-6 months post-exposure 1, 3
• For Hepatitis B (if you received vaccine), anti-HBs testing 1-2 months after the last vaccine dose 5

Precautions During Follow-Up

• Use barrier protection during sexual activity 1, 2, 3
• Do not donate blood, plasma, organs, tissue, or semen 1, 2, 3
• Seek immediate medical evaluation for any acute illness—this may indicate acute retroviral syndrome 1, 2, 3

Risk of Infection Transmission from Needlestick Injury

Comparative Transmission Risks

• The Centers for Disease Control and Prevention recommends that hepatitis B poses a dramatically higher transmission risk than HIV following needlestick injury, with HBV transmission rates reaching approximately 30% after exposure to HBeAg-positive blood compared to only 0.3-0.36% for HIV 6, 7, 8
• The risk after percutaneous exposure to HBeAg-positive blood is approximately 30% 6, 7, 8
• HBeAg-positive status is the single most important predictor of HBV transmission, with all 17 healthcare workers linked to patient transmission clusters being HBeAg-positive 6, 7, 8
• The risk of HIV transmission after percutaneous exposure is approximately 0.3-0.36% (3-4 per 1,000 exposures) 6, 7, 9
• The source patient's viral load affects HIV transmission probability 10
• Vaccination status of the exposed worker is crucial, with vaccinated workers having virtually zero risk of HBV transmission if they have protective antibody levels (anti-HBs >10 mIU/mL) 9

Prevention Hierarchy

• The most effective prevention strategy is HBV vaccination for all healthcare workers, which essentially eliminates transmission risk when protective antibody levels are achieved 9
• For HIV and HCV, strict adherence to universal precautions, safety-engineered devices, and hands-free techniques for sharp instruments remain the primary prevention methods 10

Management of Needlestick Injury

Hepatitis C Management

• If HCV seroconversion occurs, refer immediately to a hepatology specialist for evaluation of early antiviral therapy, as limited data suggest treatment may be beneficial when started early in acute HCV infection, according to the MMWR Recommendations and Reports 11

Immediate First Aid

• Wash the puncture site promptly with soap and water and avoid squeezing or applying pressure, as pressure does not reduce transmission risk. 15

Documentation and Reporting

• Record comprehensive exposure details – date and time of injury, type of device, depth of puncture, visibility of blood, body fluid involved, source‑patient information (if known), and whether the skin was intact or breached – to enable accurate risk assessment and eligibility for post‑exposure prophylaxis. 15

Source‑Patient Evaluation

• Identify the source individual whenever possible and obtain consented testing for HIV antibody, hepatitis B surface antigen (HBsAg), and hepatitis C antibody (anti‑HCV) as soon as feasible to guide prophylactic decisions. 15

Risk Assessment for Intact Skin

• Do not assume that intact skin eliminates transmission risk; prolonged exposure of large skin areas may still warrant case‑by‑case evaluation. 15

Prohibited Decontamination Practices

• Avoid applying caustic agents (e.g., bleach) or injecting antiseptics into the wound, as these measures are not recommended and provide no benefit. 15
