Patient-provider Decision Aid for HIV Post-exposure Prophylaxis Following Sexual Assault

Overview

The goal of this trial is to pilot a digital, interactive patient-provider HIV PEP decision aid. The decision aid will incorporate five sections of content: 1) key clinical factors input by providers; 2) tailored multimedia-based HIV risk sharing information; 3) standardized multimedia educational messaging regarding the effectiveness, risks, and benefits of HIV PEP; 4) direct comparisons of priorities (e.g., physical well-being - "I want to do everything I can to prevent HIV," privacy - "I don't want others to know about the exposure," or cost - "I can't afford the pills'') completed by patients; and 5) tailored feedback regarding patient priorities for use in shared clinical decision making.

HIV post-exposure prophylaxis (PEP) decision-making following nonoccupational exposures (e.g. sexual assault, intravenous drug use (IVDU), consensual condomless sex) is a complicated clinical dilemma for patients and providers. HIV PEP is a highly effective course of antiretroviral medications taken for 28 days after an exposure. The estimated cost of lifetime HIV treatment is $326,000,3 and HIV PEP is cost effective for high risk exposures. Each year approximately 300,000 people in the US are sexually assaulted. For those who present for acute medical care following sexual assault, discussing HIV PEP is recommended by the International Association of Forensic Nurses (IAFN), Association of Nurses in AIDS Care, World Health Organization (WHO), and Department of Justice (DOJ).8-10 Despite its efficacy and these recommendations, HIV PEP remains inconsistently offered and initiated in sexual assault patient population. Patient's must decide to take HIV PEP within 72 hours of an exposure. HIV PEP is not effective when initiated more than 72 hours after a potential exposure. These are not ideal conditions for making complex decisions. Patients report discussions regarding potential HIV exposure following sexual assault can cause an emotional response and asked providers to "do more" regarding explaining the realities of daily HIV PEP. Patients in the investigators' prior and ongoing work described inconsistent provider communication on the need for HIV PEP and lack of clarity regarding HIV risk as main barriers to decision making. Provider HIV PEP provision patterns indicate important inequities in post-sexual assault HIV PEP patient care. The Centers for Disease Control and Prevention (CDC) guidelines include recommendations for HIV PEP following a non-occupational exposure, however there is a large gray area: decisions should be made on a "case-by-case" basis when the HIV status of the source is unknown. This translates into variations in clinical practice. Studies examining providers' behavior in offering HIV PEP to patients following sexual assault indicate they are influenced by factors such as pre-existing relationship between patient and the perpetrator, patient age, patient and perpetrator race, and anticipated patient financial burden. Additionally, in a survey previously conducted by the investigators, Sexual Assault Nurse Examiner (SANE) program coordinators reported a perception that patients "don't, won't, or can't follow-up" as a key reason for not offering HIV PEP routinely. While not examined in HIV PEP, decision aids facilitate patient-provider communication and decision making. A 2017 Cochrane review of decision aids found patients who used a decision aid felt more informed about their decision and reported less decisional conflict. Patient-provider communication also improved. Therefore, the goal of this pilot test a digital, interactive patient-provider HIV PEP decision aid. The decision aid will incorporate five sections of content: 1) key clinical factors input by providers; 2) tailored multimedia-based HIV risk sharing information; 3) standardized multimedia educational messaging regarding the effectiveness, risks, and benefits of HIV PEP; 4) direct comparisons of priorities (e.g., physical well-being - "I want to do everything I can to prevent HIV," privacy - "I don't want others to know about the exposure," or cost - "I can't afford the pills'') completed by patients; and 5) tailored feedback regarding patient priorities for use in shared clinical decision making.
