The Centers for Disease Control and Prevention (CDC) recommends that emergency departments (EDs) and other health care facilities conduct HIV and HCV screening to identify and link to care those with undiagnosed infections. Screening for both infections in EDs is preferable due to: the shared overlap of some risk behaviors for HIV and HCV acquisition (e.g., drug use) the relatively high co-occurrence of these infections in some populations the more complex medical needs and worse sequelae for those co-infected, and efficiency. Although some EDs have experimented with dual HIV and HCV screening, best practices on how to conduct screening so as to maximize patient screening uptake have yet to be identified.

In this pilot RCT, the investigators will examine the efficacy of the persuasive health communication intervention in convincing adult ED patients who decline rapid HIV/HCV screening to be tested for these infections. Adult ED patients who decline rapid HIV/HCV screening will be randomly assigned to the ED medical staff arm or the HIV/HCV counselor arm. Within each arm, participants further will be randomly assigned to receive the persuasive health communication intervention or to watch a CDC HIV/HCV testing brochures-based video. Following the intervention or control condition, all participants will be offered rapid HIV/HCV testing again.

The investigators will conduct this R34 project at the Rhode Island Hospital ED, the primary site for many of the research team's previous HIV (Human Immunodeficiency Virus) and HCV (Hepatitis C Virus) testing studies. Dr. Beaudoin (PI) is an attending physician at the Rhode Island Hospital ED. Our multi-disciplinary team consists of researchers with extensive experience in HIV and HCV testing research, intervention development and testing, and qualitative, quantitative and cost-effectiveness research.

First, the investigators will examine our primary objective in this R34 pilot RCT( Randomized Controlled Trial) of comparing the persuasive health communication intervention to the video. Second, the investigators can compare WITHIN study arms (HIV/HCV counselor arm, ED medical staff arm) and ACROSS these study arms uptake of HIV/HCV testing among participants. Second, the design permits the investigators to obtain initial efficacy data of the persuasive health communication intervention when used by HIV/HCV counselors vs. ED medical staff (ACROSS study arms), as well as compared to the video (WITHIN study arms). Third, the design replicates our subsequent R01 RCT when the investigators compare HIV/HCV screening uptake when conducted solely by HIV/HCV counselors vs. ED medical staff.
