Nonoccupational postexposure prophylaxis (nPEP) programs offer antiretroviral therapy to prevent HIV following at-risk exposures like sexual assault. We investigated the levels of elective nPEP uptake among sexual assault cases presenting for emergency medical care. ⋯ We found that 62% of eligible sexual assault cases started nPEP. Key groups most likely to decline nPEP included female cases, those who arrived by ambulance, and those with known assailants. Providers can use these findings to provide recommendations to sexual assault survivors most likely to decline nPEP, yet still in need of care.
