    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)

    If indicated, PEP should be started in conjunction with infectious disease consultation, as well as gathering information about the source patient and his or her medication regimen.
