Research suggests nonoccupational post exposure prophylaxis (nPEP) is under prescribed for people seeking treatment within 72 h of human immunodeficiency virus (HIV) exposures in the emergency department (ED). This study is an assessment of ED prescribers' knowledge, attitudes and practices regarding administration of HIV nPEP.

This was an anonymous survey based on literature review and modified Delphi technique. We approached 153 ED participants at work over a 4-month period from 5 hospital-based and 2 freestanding EDs. There were 152 completed surveys: 80 attendings, 27 residents, and 44 physician assistants.

The majority of those surveyed (133/149, 89.3%) believe it is their responsibility to provide HIV nPEP in the ED. Although 91% (138/151) and 87% (132/151) of participants are willing to prescribe nPEP for IV drug use and unprotected sex, respectively, only 40% (61/152) of participants felt they could confidently prescribe the appropriate regimen. Only 25% (37/151) of participants prescribed nPEP in the last year. Participants considered time (27%), connecting patients to follow-up (26%), and cost to patients (23%), as barriers to prescribing nPEP.

This study identified perceived barriers to administration of nPEP and missed opportunities for HIV prevention in the ED. Although most ED prescribers were willing to prescribe nPEP and felt it is their responsibility to do so, the majority of prescribers were not confident in prescribing it. The most commonly cited barriers to prescribing nPEP were time and access to follow-up care.
