138 What are the Risk Factors Affecting PrEP Utilization Among Black Cisgender Women Who Are At Higher Risk Of HIV Acquisition?

OBJECTIVES/GOALS: The HIV acquisition rate is higher for cisgender black women in the United States. This population has a much lower use of FDA-approved pre-exposure prophylaxis drug (PrEP) for HIV prevention. This systematic literature review examines factors that hinder PrEP use among cisgender black women. METHODS/STUDY POPULATION: PubMed, CINAHL, and Cochrane were used to conduct a systematic literature search. Inclusion and exclusion criteria were predetermined to narrow down the search and to identify the appropriate studies. The retrieved literature was exported to EndNote for deduplication. The literature was then uploaded into Rayyan for title and abstract screening. The two collaborators were blinded to limit bias. Literature characterized as conflict was resolved by an independent, third collaborator. Full-text screening of the selected studies was done and a PRISMA flow diagram was developed for identification, screening, eligibility, and to detail included literature. RESULTS/ANTICIPATED RESULTS: 185 articles were obtained from the systematic literature search. 172 were excluded and 13 full-text articles were accessed for eligibility. One was removed. 12 studies involving 974 study participants met inclusion criteria for analysis. Despite the disproportionally high risk of HIV infection, black women only represented 29% of the study participants. Top three barriers to low PrEP use were stigma, socio-economic factors, and personal factors. Stigma included concerns about HIV and sexuality. Socio economic barriers were related to homelessness and low income. Personal factors included substance abuse, incarceration, and commercial sex work. The data confirms that these risk factors were not always rigid but changed based on patient characteristics and external factors. DISCUSSION/SIGNIFICANCE: The study outcomes confirmed a multitude of risk factors that serve as impediments in the use of PrEP among cisgender black women. When these risk factors are identified and addressed, the decision to use PrEP among cisgender black women may increase, therefore this warrants further investigation.
