Development and Refinement of a Persuasive Health Communication Intervention to Persuade Adult Emergency Department Patients to be Screened for HIV and Hepatitis C

Abstract

Screening for HIV and hepatitis C (HCV) in emergency departments (EDs) allows patients to benefit from life-saving treatment; however, some patients at risk for these infections decline to be tested. Interventions that overcome patient reluctance to be screened are needed so that infected patients can be linked with care. In this project, we developed a very brief, theory-based, persuasive health communication intervention (PHCI) drawn from our previous research that can be integrated into usual clinical practice. The intervention was revised with the assistance of stakeholders who would likely either deliver the intervention (ED medical staff or HIV/HCV counselors) and those who would receive it (adult ED patients). The final version of the intervention was rated as both persuasive and respectful of ED patients who initially declined HIV/HCV testing.

Introduction

The United States (US) Centers for Disease Control and Prevention (CDC) recommends that emergency departments (EDs) and other healthcare facilities in the US screen patients for HIV and hepatitis C (HCV) (Branson et al., 2006; Centers for Disease Control and Prevention, 1998; Smith et al., 2012). However, many US ED patients at risk for or later diagnosed with HIV (and likely also HCV) decline testing (Czarnogorski et al., 2011; Jones et al., 1993; Weinstock et al., 2002). In our research studies, 35% to 62% of adult ED patients declined HIV/HCV screening (Merchant et al., 2009, 2011, 2014, 2015). In US EDs, patients commonly decline HIV screening out of a belief that they are not at risk (Brown et al., 2008; Christopoulos et al., 2012; Jain et al., 2012; Merchant et al., 2008; Pisculli et al., 2011; Schechter-Perkins et al., 2014; Ubhayakar et al., 2011). However, self-perceived and actual risk about HIV are frequently incongruent among ED patients (Pringle et al., 2013; Ubhayakar et al., 2011) which can contribute to losing an opportunity to identify an infection through screening. Although less studied than HIV screening, US ED patients also often decline of HCV screening due to a lack of perceived risk for HCV (Cowan et al., 2018; Merchant et al., 2014). Interventions that overcome ED patient reluctance to be tested for HIV and HCV could assist in identifying those who are unaware of their infection in order to link them with care.

We previously developed and tested interventions designed to increase adult ED patient uptake of combined HIV/HCV testing or HIV testing alone. In two randomized, controlled trials (RCTs) among adult ED patients who used drugs, we determined that a brief motivational interviewing (MI)-based intervention delivered by an HIV/HCV counselor in person was not efficacious in increasing uptake of combined rapid HIV/HCV screening (Merchant et al., 2014, 2015). We further observed in these two RCTs that most participants had already decided—before receiving the intervention—if they were going to be tested; accordingly, their decisions rendered the intervention unnecessary for those who would have agreed to be tested at the onset of the screening process. In a third RCT, we sampled the general population of adult ED patients (i.e., participants were not selected based on prior drug use or HIV risk), and found that providing patients with computer-based feedback about their self-reported HIV risk-taking behaviors from injection-drug use (IDU) and condomless sex did not increase uptake of HIV screening (Merchant et al., 2011). In fact, participants with lower or moderate risk for HIV were less likely to agree to be tested; apparently, patients believed that their risks were not high and hence declined testing, even though they reported some risk for being infected.

We learned three lessons from our prior work. First, to increase efficiency in ED-based HIV/HCV screening, interventions should be provided only to those who initially decline to be tested. Second, due to patients’ tendency to underestimate their risk, an intervention to encourage patients to be screened for HIV/HCV should not focus on risk-taking behaviors. Instead, the intervention should provide other convincing evidence of the value of testing. Third, the intervention should not be delivered using MI. Because MI is inherently non-directional and encourages decision-making only after a review of pros/cons, it can leave patients without clear guidance on the recommended course of action (in this case, to be tested for HIV/HCV). Furthermore, the time and training needed to deliver MI renders it less likely to be used in typical clinical encounters.

These lessons led us to consider instead using a persuasive health communication intervention (PHCI) to convince patients who initially declined HIV/HCV screening instead to be tested for these infections. PHCIs differ from other behavioral interventions in that they are very brief (<5 minutes), directed and focused, and intended to convince its recipient to accomplish a clearly articulated immediate goal, in this case, agree to be tested for HIV/HCV (Harrington, 2016; Kaptein et al., 2010; O’Sullivan et al., 2003; Storey et al., 2014). In this report, we describe the development and refinement of a PHCI to convince adult ED patients who initially declined combined rapid HIV/HCV screening instead to be tested for these infections. We aimed to develop a PHCI that was very brief (necessary for busy ED settings and staff with competing priorities), similar to routine clinical practice (allowing healthcare providers to incorporate it into their medical practice of persuading reluctant patients), theoretically-grounded (helping patients’ decision-making processes), and supported by prior research (to optimize feasibility, acceptability, and efficacy).

Methods

Study Purposes, Design, and Setting

The purposes of this research were to: (1) create a PHCI designed to convince adult ED patients who initially declined opt-out rapid HIV/HCV screening instead to be tested for these infections, and (2) refine the PHCI based on interviews of stakeholders who would receive the intervention (adult ED patients who had declined screening) and those who might deliver it (medical staff [nurse practitioners, physician assistants, attending and resident physicians] and HIV/HCV counselors). Interviews were performed from January through March 2019. This research was conducted at Rhode Island Hospital, which is an academic, urban, Level 1 trauma center, “safety net” adult patient ED (>110,000 ED visits/year) in Providence, Rhode Island, which is in a moderate HIV/HCV prevalence area. The study was approved by the hospital’s institutional review board.

Creation of the PHCI

The PHCI drew upon behavioral theories underlying persuasive health communications, including their recommended content and order of presentation (Harrington, 2016; Kaptein et al., 2010; O’Sullivan et al., 2003; Storey et al., 2014). Thus, the PHCI consisted of six successive components (information, education, gain, loss, common concerns, and call to action), with associated objectives for each component (e.g., the gain component comprised arguments of why the patient would benefit from being tested for HIV/HCV). Also as recommended, we included only content for the PHCI relevant to the desired behavioral outcome and purpose of each PHCI component, and not any extraneous information, details or explanations. Content was drawn from HIV/HCV materials prepared by the research team for other projects, as well as from CDC brochures and their HIV/HCV websites. The PHCI was revised until it was consistent with the underlying theory and purpose of persuasive health communications; included only essential content that presented unambiguous, clear, and concise arguments that could convince someone to be tested for HIV/HCV; could be delivered orally within 2 to 3 minutes; did not contain content linking testing to perceived, reported, or actual HIV/HCV risk; did not contain medical jargon; presented medical and public health concepts in an understandable form; was less than a sixth grade reading level in its written form; and was designed to be respectful of patient autonomy and decision-making.

Refinement of the PHCI

Participants and interviewer

Participants to assist in the refinement of the PHCI were recruited by quota according to three stakeholder groups: ED medical staff, HIV/HCV counselors, and ED patients. The ED medical staff participants (n = 15) included five attending physicians, five resident physicians, and five advanced practice providers (i.e., nurse practitioners and physician assistants). To avoid impacting future research using the PHCI in the ED where it would be subsequently evaluated, we recruited ED medical staff who worked at nearby hospitals and also graduating ED resident physicians. Likewise, we recruited HIV/HCV counselors (n = 5) who worked at the sexually transmitted disease clinic at The Miriam Hospital in Providence, Rhode Island. Patient participants (n = 24) were recruited from the study site ED. Of the 24 patients, 12 English-speaking (6 women, 6 men) and 12 Spanish-speaking (6 women, 6 men) adult (18–64 years-old) ED patients. Participants received a gift card to a local store after completing the study. The interviewer for this investigation was a research assistant (RA), who was a bilingual (English- and native Spanish-speaker) medical student who had completed 3 years of medical school. The RA underwent >10 hours of training in the interview protocol with study investigators, including mock interviews with the study investigators and other research team members, prior to interviewing participants. The RA and participants were not known to each other prior to the interviews.

Recruitment procedures

Medical staff and HIV/HCV counselors were recruited through email solicitation using lists of providers at their respective institutions. The email solicitation explained the purpose of the study. Those who responded via email affirmatively to participating were contacted further about the study via email, telephone, or in person, and an in-person interview time was chosen. At the start of these interviews, the RA reviewed the purpose of the study and what participation entailed, and obtained informed consent.

Patient participants were recruited through a process that reflected the intended audience for the PHCI, which was adult ED patients who initially declined combined rapid HIV/HCV screening. To identify possible patient participants, the RA reviewed the electronic medical record (EMR) of patients present in the ED to determine preliminary eligibility. The initial EMR review was performed to ensure that participants were not already known to be HIV or HCV infected or had been tested for HIV and HCV within the prior year. Following EMR review, the RA approached those who appeared to meet eligibility criteria and asked them to confirm their eligibility. For those who were study eligible, the RA explained the purpose of the study and what participation entailed, and for those who agreed to participate, obtained informed consent. Interviews with all participants were conducted in person.

Next, the RA initiated simulated opt-out rapid HIV/HCV screening, using the following script: “Please tell me what you would say or do if I said the following: ‘As part of a study, we are offering a random sample of patients free rapid testing for HIV and hepatitis C. HIV and hepatitis C testing is recommended by medical professionals. I would like to test you for these two infections, unless you tell me that you do not want to be tested. The test is free and you will get the test results in about 20 minutes while you are still here in the emergency department. If the test shows that you could be infected, I will help you get the care you need’. If I said that to you, would you get tested or would you instead say that you did not want to be tested?” Patients who indicated they wanted to be tested for HIV/HCV were thanked, informed that they could ask their ED medical provider to test them as part of clinical care, and were provided with a list of resources where they could be tested in the community. If patients declined HIV/HCV screening, they continued to the interview phase.

Stakeholder interviews to refine the PHCI

The purpose of the interviews was to obtain feedback from stakeholders regarding its persuasiveness, acceptability, and respect for patient autonomy. In addition, the interviews collected feedback on the intervention’s content, comprehensibility, and clarity. The interviews were based on a script that contained a series of questions that addressed 11 topic areas (See Supplemental Material). The 11 topic areas concerned: clarity, respect for patient autonomy, and the convincing quality of the PHCI as a whole; the six components of the PHCI (information, education, gain, loss, common concerns, call to action); and the completeness and an overall assessment of the PHCI as a whole. There were thirty interview questions relevant to this analysis; two on clarity, four on each of the six components of the PHCI, and one each for the remaining four topic areas. The interview script was developed by the study authors. After approximately five interviews, the PHCI was revised using the feedback from those interviews. As such, subsequent interviewees provided feedback on an iteratively revised PHCI.

Each interview session was audio-recorded. For each interview, the RA first delivered the entire PHCI without interruption to participants. Afterward, participants were asked to consider the entire message when answering questions about its clarity, respect for their choice on whether or not to be tested for HIV/HCV, and persuasiveness. Participants next were read each of the six components in order of appearance and asked to indicate content in that individual section that was not clear or they did not like, as well as how that section could be improved. At the end of the interview, participants were asked to provide suggestions on any additional content that should be included and offer an overall assessment of the PHCI. Each interview lasted 30 minutes.

Data Analyses

Three members of the research team independently reviewed the interview transcripts and summarized the feedback by interview question for each of the 11 topic areas separately for each participant group. These three team members met with the study principal investigator who moderated a discussion to summarize feedback for each interview question. Feedback was then collated across participant groups for each interview question. Participant quotations of interesting and insightful comments also were identified.

Results

Table 1 provides a summary of the feedback provided by participants for each of the 30 interview questions, organized by the 11 topic areas according to stakeholder group. Figure 1 shows both the PHCI draft prior to the stakeholder interviews and the final version of the PHCI after all revisions were made based on stakeholder feedback. Categories of revisions made to the PHCI based on stakeholder feedback along with examples of changes made are as follows:

(1) changes of phrases or word choices based on specific feedback from participants: for example, “life-saving treatment” changed to “effective treatment”;

(2) clarifications of sections that participants indicated were unclear or confusing: for example, an explanation was added about HIV’s effect on the body and its relevance, “Without treatment, HIV damages the body’s immune system that protects us from diseases”;

(3) changes or clarifications based on inferences from participant feedback that indicated a lack of participant understanding: for example, change of “. . .and for hepatitis C, whether or not you’ve been exposed. If you aren’t infected or exposed, you can rest easy. If you have been exposed to hepatitis C, we will notify you in a few days as to whether or not you are currently infected.” to “If your test results show that you are infected, you will have additional tests to confirm your diagnosis”;

(4) changes or additions to emphasize important concepts: for example, provision of support after an HIV or HCV diagnosis added, “You will also get the support you need to cope with and overcome any challenges of having HIV and hepatitis C”; and

(5) additions, deletions, or rearrangement of content: for example, removal of “peace of mind.” Suggested changes that were not in keeping with the intent or scope of the PHCI were not made, for example, providing HIV/AIDS statistics, conducting assessment of risk factors and inquiring about reasons for lack of prior testing, explaining modes of transmission, making recommendations for repeat testing, providing time to read about the topic of testing, distinguishing types of hepatitis, and explaining testing mechanisms.

Discussion

With input from stakeholders, we developed and refined a PHCI to convince adult ED patients who initially declined opt-out rapid HIV/HCV screening instead to be tested for these infections. Stakeholder input was particularly invaluable in refining the intervention. Stakeholders in this project were those who would either deliver or receive the PHCI, and as such were the ideal group needed to shape the content of the intervention to improve its clarity and persuasiveness. Of importance, participants believed that the PHCI was respectful of patient decision-making on acceptance or decline of HIV/HCV screening, and their input helped to ensure that it maintained patient autonomy. The next phase of our research will assess the efficacy of the intervention in increasing uptake of HIV/HCV screening in the ED setting.

The immediate implication of this project is that it demonstrates a PHCI aimed to increase acceptance of HIV/HCV screening among ED patients can be refined through the input of stakeholders, particularly ED patients, ED medical staff, and HIV/HCV counselors. As such, this work serves as a model, or at least as an example, for stakeholder involvement in producing behavioral interventions in this setting. We provide in this manuscript a detailed description of those processes and how it yielded the final product. The subsequent phase of our research which utilizes the PHCI in the ED for HIV/HCV screening hopefully will demonstrate its value.

Although we obtained a variety of stakeholder perspectives, we acknowledge as a limitation of this work is that the perspectives obtained cannot reflect the views of those who declined to participate or had demographic characteristics different from those who were included in the study. The study was conducted in a single city in the northeastern US and only involved adult English- or Spanish-speaking patients at a “safety net” academic hospital. As such, interviews of other patients and healthcare workers with different demographic characteristics could have led to different intervention content. Interpretation of the interviews and resultant revisions also reflect the views of the research team, which was reflected in the changes made. However, the iterative nature of the changes with consequent stakeholder feedback helped to keep the PHCI from being based solely on the research team’s perspectives. Finally, the PHCI’s efficacy was not examined in this investigation, which will be conducted in future research.

In conclusion, with the assistance of stakeholders, we produced a very brief, theory-based intervention guided by prior theory and research and feasible for use in usual clinical practice. Stakeholders found it to be convincing while respectful of patient autonomy and decision-making.
