    HIV Needle Stick Risk Assessment Stratification Protocol (RASP)

    Quantifies HIV exposure risk by source and exposure type and need for prophylaxis.
    When to Use
    Why Use
    • High vs low risk exposure; helps determine whether or not to start PEP.
    • Always try to test the source patient for HIV, and other infectious diseases such as Hepatitis C and Hepatitis B.

    The HIV Needle Stick Risk Assessment Protocol quantifies gives healthcare workers a more objective risk assessment of getting HIV after a needle stick.

    Known HIV+: acute AIDS illness
    Known HIV+: asymptomatic HIV
    Unknown HIV status: high-risk situation
    Unknown HIV status: low-risk situation
    Fresh blood
    Other high-risk fluids (e.g., semen)
    Dried old blood
    Low-risk secretions (e.g., tears, urine, saliva)
    Deep intramuscular
    Deep transcutaneous with visible bleeding
    Superficial transcutaneous without bleeding
    Mucosal contact only
    Intact skin
    Massive (e.g., transfusion)
    Measurable (>1 mL)
    Moderate (large-bore, hollow needle >22 g)
    Small (small-bore, hollow needle <22 g)
    Trace surface only (e.g., suture needle)
