Regional variation in HIV clinical trials participation in the United States

Attitudes Toward Payment for Research Participation: Results from a U.S. Survey of People Living with HIV

Little is known about how payment affects individuals' decisions to participate in HIV research. Using data from a U.S. survey of people living with HIV (N = 292), we examined potential research participants' attitudes toward payment, perceived study risk based on payment amount, and preferred payment forms, and how these factors vary by sociodemographic characteristics. Most respondents agreed people should be paid for HIV research participation (96%) and said payment would shape their research participation decisions (80%). Men, less formally educated individuals, and members of some minoritized racial-ethnic groups were less likely to be willing to participate in research without payment. Higher payment was associated with higher perceived study risks, while preferences for form of payment varied by age, gender, education, race-ethnicity, and census region of residence. Findings suggest payment may influence prospective research participants' risk-benefit calculus and participation, and that a one-size-fits-all approach to payment could differentially influence participation among distinct sociodemographic groups.

Factors Influencing Successful Recruitment of Racial and Ethnic Minority Patients for an Observational HIV Cohort Study in Washington, DC

The process of recruiting racial and ethnic minority persons living with HIV (PLWH) is important for research studies to ensure inclusivity of underrepresented groups. To understand factors associated with recruitment of minority PLWH, this study examined the recruitment process of PLWH for an observational study of their routine medical care at 14 clinics in Washington, DC. Research assistant (RA) recruiters were interviewed to assess their consenting processes and strategies. Data were collected on clinic services, patient demographics, and recruitment logs of patient approaches for obtaining informed consent resulting in agreement or refusal. A median of 96% of eligible patients was approached to obtain consent, yielding a median consent rate of 78% across all sites. A total of 8438 patients consented and 1326 refused study participation. Clinical sites with more comprehensive services had higher consent rates. black/African American and Hispanic/Latinx PLWH consented or refused study participation in similar proportions, while significantly more white patients enrolled than refused. More men, compared with women, enrolled than refused study participation. The most frequent reasons for refusing study participation were the lack of interest in research (33.2%) and no specific reason provided (28%). RAs identified that effective recruitment strategies used culturally sensitive approaches, built rapport with patients, and obtained provider support for the study. Recruitment strategies that are gender sensitive to address the disparity of underrepresentation of women, address perceived barriers, and examine clinic-specific services are needed to maximize research participation for minority PLWH to improve prevention and health outcomes.

Cultural Competence and Humility in Infectious Diseases Clinical Practice and Research

Infectious diseases as a specialty is tilted toward social justice, and practitioners are frequently on the front lines of the battle against health inequity in practices that are diverse and sometimes cross international borders. Whether caring for patients living with the human immunodeficiency virus, tuberculosis, or Ebola, infectious diseases practitioners often interact with those at the margins of societies (eg, racial/ethnic/sexual/gender minorities), who disproportionately bear the brunt of these conditions. Therefore, cultural barriers between providers and patients are often salient in the infectious diseases context. In this article, we discuss cultural competence broadly, to include not only the knowledge and the skills needed at both the organizational and the individual levels to provide culturally appropriate care, but also to include "cultural humility"-a lifelong process of learning, self-reflection, and self-critique. To enhance the quality and the impact of our practices, we must prioritize cultural competence and humility and be mindful of the role of culture in the patient-provider-system interactions, in our larger healthcare systems, and in our research agendas and workforce development.

Outcomes of a Career Development Program for Underrepresented Minority Investigators in the AIDS Clinical Trials Group

We surveyed awardees of the Minority HIV Investigator Mentoring Program (MHIMP) of the AIDS Clinical Trials Group. Most reported clinical specialization in infectious diseases or HIV medicine (86%), and all but 1 (95%) are engaged in medical/health sciences research. The MHIMP helped retain early-career minority investigators in HIV/AIDS-related research.

A Demographic Analysis of Racial/Ethnic Minority Enrollment Into HVTN Preventive Early Phase HIV Vaccine Clinical Trials Conducted in the United States, 2002-2016

OBJECTIVES

Racial/ethnic minority communities in the United States are overrepresented among new HIV diagnoses, yet their inclusion in preventive HIV vaccine clinical trials is inadequate. An analysis of enrollment demographic characteristics from US preventive HIV vaccine clinical trials from 1988 through 2002 showed that enrollment of racial/ethnic minority groups increased. We analyzed enrollment in preventive HIV vaccine clinical trials from 2002 through 2016 and compared our data with data from the previous study, described demographic characteristics of trial participants, and assessed how well this distribution reflected the racial/ethnic distribution of new HIV diagnoses in the United States.

METHODS

We examined data on demographic characteristics from 43 Phase 1 and Phase 2A preventive HIV vaccine clinical trials conducted in the United States and compared the results with those of the previous study. We also compared racial/ethnic distributions from 2011 through 2015 with Centers for Disease Control and Prevention data on the number of new HIV diagnoses during the same period.

RESULTS

Of 3469 participants, 1134 (32.7%) identified as a racial/ethnic minority, a 94% increase from the previous period (634/3731; 17.0%). Percentage annual enrollment of all racial/ethnic minority participants fluctuated from 17% to 53% from mid-2002 to 2016. Percentages of new HIV diagnoses among the general population were 1.9 to 2.9 times the percentage enrollment of black participants and 1.3 to 6.6 times the percentage enrollment of Hispanic/Latino participants in clinical trials for the same period.

CONCLUSIONS

Although enrollment of racial/ethnic minority groups into HIV vaccine clinical trials has increased, it is not proportional to the number of new HIV diagnoses among these groups. To enhance recruitment of racial/ethnic minority groups, the HIV Vaccine Trials Network has prioritized community partnerships and invested resources into staff training.

Research participation, trust, and fair compensation among people living with and without HIV in Florida

Florida has the second highest number of newly diagnosed cases of HIV in the United States. Sociodemographic representation that is reflective of the population is essential in developing evidence based interventions to improve HIV outcomes and reduce disparities. Understanding HIV research trial participation, preferences for types of research, and fair compensation for research will further our understanding of someone's decision to participate in research. The purpose of this analysis was to identify differences in prior research participation, trust, interests in types of research, and fair compensation between people living with HIV and without HIV in North Central Florida. In this sample of 8340 people interviewed in the community about their health concerns and research participation, 156 reported living with HIV. Only 20.5% of people with HIV reported past participation in research, however 94.2% said they were interested in future research participation. While people with HIV were slightly more interested in higher risk/low convenience research, there were no statistically significant differences in preferences for types of research between those with and without HIV. People with HIV reported no difference in the amount they would request for fair compensation ($78.4 USD) compared with those without HIV ($72.2 USD, p = 0.69). Community members are interested in participating in research, although few had previously participated. Improving our understanding of research study participation will help improve recruitment efforts and draw stronger conclusions regarding the effectiveness of interventions, as well as enhance implementation of these interventions.

Beliefs About Anal Cancer among HIV-Infected Women: Barriers and Motivators to Participation in Research

BACKGROUND

Infection with the human immunodeficiency virus (HIV) remains associated with a greater risk of anal cancer, despite widespread use of combination antiretroviral therapy. Evidence concerning the acceptability of anal cancer screening gives little attention to women. Because HIV-infected women have a high prevalence of depression and history of sexual trauma, understanding acceptability among this group is critical.

PURPOSE

We sought to assess barriers and motivators to participation in anal cancer screening research among a racial/ethnically diverse HIV-infected female population.

METHODS

We conducted a survey based on the Health Belief Model to identify characteristics of women willing to participate in anal cancer screening research (n = 200). Bivariate analyses examined associations between willingness to participate and sociodemographics, clinical characteristics, and health beliefs. Logistic regression modeled willingness to participate in research.

MAIN FINDINGS

Of the women who participated, 37% screened positive for depression, 43% reported a high trauma history, and 36% screened positive for posttraumatic stress disorder. Overall, 65% reported willingness to participate in research. Those likely to participate were older, reported intravenous drug use as their HIV risk factor, and had a history of prior high-resolution anoscopy (HRA) compared with those unwilling to participate. The most commonly reported barrier to anal Pap testing was fear of pain. In adjusted analyses, a lack of fear of pain and prior experience with HRA significantly predicted willingness to participate.

CONCLUSIONS

Findings suggest that, to increase participation in anal Pap and HRA-related research for HIV-infected women, a single approach may not be adequate. Rather, we must harness patients' previous experiences and address psychosocial and financial concerns to overcome barriers to participation.
