ED2PrEP - patient focused, low-burden strategies for PrEP uptake among emergency departments patients: a cross-over hybrid implementation-effectiveness trial

Project: Research project

Project Details


Severe inequities in HIV pre-exposure prophylaxis (PrEP) access and use persist among Black and Latinx communities most impacted by the HIV epidemic. The Bronx, NY, with over 90% of the population identifying as Black or Latinx, is an Ending the HIV Epidemic (EHE) priority county with the fifth highest HIV diagnosis rate in the U.S. and the lowest PrEP use in NY. Research on barriers to PrEP engagement indicate that the current structure of PrEP access and management is not consonant with the lives, priorities, or needs of the hardest hit communities, further exacerbating ongoing racial/ethnic and socioeconomic disparities in HIV incidence. Many of the same barriers leading to poor PrEP uptake in Black/Latinx communities also drive members of these communities to seek care for sexually transmitted infections (STIs), a known risk factor for HIV, in Emergency Departments (EDs). However, there is a discordance between the type of care likely to preserve the long-term health of those seeking STI care in EDs (longitudinal, behavioral, and prevention-oriented) and the care the ED is optimized to provide (acute, high intensity, life-saving/stabilizing), meaning that both patients and health systems stand to gain from a restructuring of how STI care is delivered in EDs. Innovative, efficient, and sustainable strategies for identifying and engaging high priority populations for HIV prevention seeking sexual healthcare in EDs are thus needed. We therefore propose ED2PrEP, a pragmatic Type III hybrid effectiveness-implementation trial comparing two strategies for increasing PrEP uptake among patients at risk for HIV accessing care in Bronx EDs. The two strategies are (1) Post-Visit Outreach (PVO) involving proactive outreach to patients following a STI-related ED visit. PVO will be initiated by a Sexual Health Navigator who will provide PrEP education, counseling, and linkage to existing sexual health/PrEP clinics. (2) Tele-PrEP (TP) will involve a real-time telehealth visit with a Sexual Health Provider during STI-related ED visits. TP will also include education, counseling, and linkage, in addition to the provider’s ability to prescribe PrEP at the time of the visit. To test the effectiveness of PVO and TP for increasing PrEP uptake among patients accessing STI care in the ED, we will perform a crossover trial in which the strategies are implemented in two different EDs for 9 months and then switched for another 9 months (Aim 1). Next, guided by the RE-AIM framework, we will assess implementation outcomes for the strategies to identify how each strategy’s effectiveness is impacted by implementation considerations (Aim 2). Finally, to inform scale-out locally and nationally, we will perform an economic analysis to determine each strategy’s cost per outcome and relative cost-effectiveness (Aim 3). ED2PrEP will generate critical data that could transform how EDs initiate PrEP and engage populations at the highest risk for HIV and accelerate EHE goals in one hardest hit jurisdictions in the U.S. Findings could also be informative to other jurisdictions, having dramatic effects on how HIV prevention is delivered.
