HIV Needle-Stick Risk Assessment Stratification Protocol (RASP)

Structured risk stratification tool guiding post-exposure prophylaxis (PEP) decisions following occupational or non-occupational HIV exposure. Considers source HIV status, exposure type, and clinical context to determine PEP indication.

Score interpretation

PEP Not Indicated -5–-1

PEP not indicated — exposure >72 hours OR source HIV-negative OR minimal exposure to intact skin

→ No PEP required; document exposure and decision clearly; wound management (wash with soap and water, irrigation of mucous membranes); follow-up HIV test at 6 weeks and 12 weeks; occupational health or sexual health clinic documentation; address root cause of exposure; advise on window period and symptoms of seroconversion

Low Risk — PEP Discussion 0–1

Low-risk exposure — PEP may not be warranted but expert review recommended

→ Consult occupational health or ID specialist urgently (<2 hours); risk-benefit discussion with patient; if source available, expedite HIV testing; if source HIV+ and undetectable VL = U=U (Undetectable = Untransmittable); wound care; baseline HIV serology; consider PEP if patient anxious or if any doubt; support and counselling

Significant Risk — PEP Recommended 2–10

Significant HIV exposure risk — initiate PEP as soon as possible (<72 hours)

→ Start PEP ASAP (ideally within 2 hours, must be <72 hours): tenofovir/emtricitabine + raltegravir or dolutegravir (28-day course); baseline HIV test, HBV, HCV, FBC, U&E, LFT; report to occupational health/ID service; follow-up at 4 weeks (toxicity), 8 weeks; HIV test at 6 and 12 weeks post-exposure; Hep B immunoglobulin if unvaccinated source HBsAg-positive; psychological support
