pre-exposure prophylaxis in the emergency department

Conditions: HIV/AIDS; PrEP

Summary: despite an increasing armamentarium of behavioral and biomedical hiv prevention methods, since 2010 rates of new infection have remained around 40,000 annually. the demonstrated efficacy and subsequent approval of emtricitabine/tenofovir disoproxil fumarate for pre-exposure prophylaxis (prep) for hiv by the fda in 2012 was thought to represent a turning point that could significantly reduce the number of new infections. since approval, the promise of prep as a transformative intervention has yet to be realized. despite the implementation of systems for clinical evaluation for and initiation of prep by primary care providers, hiv specialists, and sti clinics, numerous barriers to prep expansion have been identified, including: 1) patient and provider lack of knowledge, 2) lack of access to medical care among high-risk individuals, 3) provider discomfort and inexperience with screening for risk behaviors, and 4) insurance and affordability. this proposal seeks to expand access to and engagement in prep among high risk individuals though an innovative delivery approach in the emergency department (ed) while addressing these four barriers.

aim 1: initiate a targeted ed-based prep screening program and optimize its feasibility and acceptability. 1. behavioral risk factor eligibility screening will be performed using the icap pre-exposure prophylaxis (prep) screening for substantial risk and eligibility tool. 2. during a 3-month period, use continuous quality improvement methods to decrease the time for completion of prep eligibility screening to an interval that is acceptable to ed patients and providers. aim 2: pre-exposure prophylaxis provision in the ed (prepped) trial: identify 40 prep eligible patients over a 12-month period who are interested in initiating prep in the ed. these patients will be offered immediate prep (iprep) initiation in the ed with facilitated linkage to comprehensive out-patient care. 1. evaluate the impact of a prep "starter pack" on patients agreeing to iprep. the primary outcome is engagement in care at 30-days post prep initiation visit. secondary outcomes include retention in care, sti diagnosis, risk behavior and prep adherence. 2. collect data on recruitment and attrition rates, as well as means and standard deviations for key measures that will be needed to plan a definitive trial of ed-initiated prep.
