HIV_Needle_Stick_Risk_Assessment_Stratification_Protocol_guideline v.1
HIV Needle Stick Risk Assessment Stratification Protocol (RASP) quantifies HIV exposure risk by source and exposure type and the need for prophylaxis.
To help healthcare workers decide on the use of postexposure prophylaxis (PEP) for HIV exposure.
HIV Needle Stick Risk Assessment Stratification Protocol (RASP) variables and related values: - Source population (Acute AIDS illness defined as “end-stage AIDS, hospitalized, high viral load” Unknown HIV status, high-risk situation defined as “suspected HIV, IV drug user, an unknown needle with high local HIV prevalence”): Known HIV+: acute AIDS illness=1, Known HIV+: asymptomatic HIV=10, Unknown HIV status: high-risk situation=100, Unknown HIV status: low-risk situation=1000. - Inoculum type: Fresh blood=1, Other high-risk fluids (e.g., semen)=10, Dried old blood=100, Low-risk secretions (e.g., tears, urine, saliva)=1000. - Method of transmission: Intravenous=1, Deep intramuscular=10, Deep transcutaneous with visible bleeding=100, Superficial transcutaneous without bleeding=200, Mucosal contact only=500, Intact skin=1000. - Volume of inoculum: Massive (e.g., transfusion)=100, Measurable (>1 mL)=10, Moderate (large-bore, hollow needle >22 g)=5, Small (small-bore, hollow needle <22 g)=3, Trace surface only (e.g., suture needle). Formula: Basic risk = 1 / (Source population x Inoculum type x Method of transmission) Total risk = Basic risk x Volume of inoculum
