Brief 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.

Detailed description

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.

MeasureTime frameDescription
CDC Sexual Behavior Questions (CSBQ) (RCT Component)30 days post-ED visitCDC Sexual Behavior Questions (CSBQ) to measure HIV risk behavior. CSBQ is a multi-tiered, gender-specific questionnaire developed by the Centers for Disease Control and Prevention HIV-STID Behavioral Surveillance Working Group. Three separate domains - Sexual Behavior, Drug-related HIV risk, and HIV testing. Responses are yes/no with no summation. Number of participants who engaged in unsafe sexual behavior, was under substance influence and who had a HIV test.
PrEPPED Satisfaction and Acceptability Survey (RCT Component)30 days post-ED visitPrEPPED Satisfaction and Acceptability Survey is a patient satisfaction questionnaire was developed by the study team. It's a series of independent Likert questions from 1-6 addressing different aspects of the program. Full scale from 0 to 18, with higher score indicating more satisfaction. Satisfaction data were not collected at 30, 60, or 90 days. After study initiation, it was determined by the researchers that the satisfaction items were specific to the emergency department visit experience and not relevant to the follow-up period. Consequently, decision was made to not administer the follow-up satisfaction assessments, therefore, no data was collected so there is no data to report.
Number of Participants of New HIV Infection (RCT Component)90 days post-ED visitNumber of new HIV diagnosis at 90-days after enrollment. This question was only asked for those individuals who had not been lost to follow-up.
Number of Participants of New STI Diagnoses (RCT Component)30 days, 60 days, and 90 days post-ED visitNumber of new STI diagnosis between day 1 (day after enrollment) and day 90 (final day of follow-up) broken down into days 1-30, 31-60, 61-90.
The VSQ-9 is a Visit-specific Satisfaction Instrument (RCT Component)30 days post-ED visitThe VSQ-9 is a visit-specific satisfaction instrument adapted by the American Medical Guidelines Regimen Information Program (GRIP) survey. GRIP guide is a self-report to assess PrEP adherence at 30-days post ED visit, with 6 categorical items: excellent, very good, good, fair, poor, and very poor. Because participants were not required to follow up at a single clinic, post-discharge care settings varied widely. The VSQ-9 assesses satisfaction with a specific clinical encounter, and applying it across multiple, non-standardized settings was deemed inappropriate and unlikely to yield interpretable data. Therefore, decision was made by the researcher to not administer the VSQ-9 at 30, 60, or 90 days. Consequently, no follow-up VSQ-9 data were collected so there is no data to report.

Population: No protocol amendment was generated for this Outcome Measure. Although the outcome was prespecified in the initial protocol, the study team ultimately determined during implementation that the required data elements could not be collected reliably across sites. Because this decision did not alter the study intervention, eligibility criteria, procedures, or primary outcome, and because no participant-facing activities were affected, the team did not submit a formal protocol amendment at the time.
