Mistrust among minorities and the trustworthiness of medicine

Technological Innovations to Improve Patient Engagement in Nephrology

Technological innovation has accelerated exponentially over the last 2 decades. From the rise of smartphones and social media in the early 2000s to the mainstream accessibility of artificial intelligence (AI) in 2023, digital advancements have transformed the way we live and work. These innovations have permeated health care, covering a spectrum of applications from virtual reality training platforms to AI-powered clinical decision support tools. In this review, we explore fascinating recent innovations that have and can facilitate patient engagement in nephrology. These include integrated care mobile applications, wearable health monitoring tools, virtual/augmented reality consultation and education platforms, AI-powered appointment booking systems, and patient information tools. We also discuss potential pitfalls in implementation and paradigms to adopt that may protect patients from unintended consequences of being cared for in a digitalized health care system.

Trust and Biomedical Research Engagement of Minority and Under-Represented Communities in Mississippi, USA

Trust is critical to the development and maintenance of effective research collaborations and community engagement. The purpose of this study was to assess the current attitudes and level of trust pertaining to health research among residents of Central Mississippi, the priority health region for the Research Centers in Minority Institutions (RCMI) Center for Health Disparities Research (RCHDR) at Jackson State University. The cross-sectional study was conducted from November 2021 to April 2022. The data were analyzed using descriptive statistics carried out by SPSS statistical software. A total of 146 participants responded to the survey. The participants were predominately African American (99%) and female (75%). Historical research studies, the researchers' qualities, and potential benefits from participation were factors affecting the level of trust in the research process. Ninety percent (n = 131) expressed that it was important to be involved in the research process, and 98.5% (n = 144) agreed that discussing the research findings with the participants was important for establishing trust in the research process. While trust in the research process does not guarantee participation, trust is a precursor for those who decide to engage in health disparities research. Key findings will be integrated into the RCHDR research agenda to foster further development and implementation of innovative community-based participatory research toward the control and/or prevention of diseases that disproportionately affect minority and under-represented populations in Mississippi.

Current status of inclusion of black participants in neuropsychological studies: A scoping review and call to action

In recognition that insufficient diversity in research impedes the generalizability of findings and negatively impacts clinical outcomes, the 1993 National Institutes of Health (NIH) Revitalization Act required NIH-funded clinical trials to include and assess outcomes for women and minority participants. Since that time, the American Psychological Association (APA) and the American Academy of Clinical Neuropsychology (AACN) have also acknowledged the reporting of this information as an essential element of research, and they have established similar aspirational goals. Nevertheless, Black communities remain disproportionately underrepresented in neuropsychology research. The objective of this study was to investigate current levels of inclusion and reporting of Black research participation in neuropsychological studies.

Publications from high impact neuropsychology journals between 2019-2020 were selected via established methodologies. Studies were analyzed to determine the rates of demographic inclusion and reporting of minority, particularly Black, participants.

A total of 1,764 articles were reviewed across seven neuropsychology journals. Of the 653 studies not excluded for other reasons, 43% neglected to include sufficient information about participants' race/ethnicity. Of the subset of eligible studies that did include racial/ethnic demographic information (n = 349), only 61% included any Black participants at all. Only 34.1% of them included enough Black participants equal to or greater than the proportion of Black individuals within the United States.

Setting a standard of routinely reporting and analytically reflecting on demographic information is necessary to make valid inferences regarding disease sequelae, treatment, and public health strategies. The authors offer specific recommendations to improve the inclusion and reporting of Black research participation, ensure compliance with established policies, and improve the quality of neuropsychological research.

Adherence and retention of African Americans in a randomized controlled trial with a yoga-based intervention: the effects of health promoting programs on cardiovascular disease risk study

Objectives: Sedentary lifestyle is a risk factor for cardiovascular disease (CVD). Few alternative lifestyle interventions, such as yoga practice, focus on African Americans (AA), the population most vulnerable to CVD. Our objective is to compare the retention and adherence rates between yoga, walking, and health education interventions while providing information about the acceptance of various yoga regimens. Design: Three hundred seventy-five AA participants were recruited exclusively from an active cohort study and randomized into a 48-week study (24 weeks intervention, 24 weeks follow-up) with 5 health promotion interventions: high frequency yoga, moderate frequency yoga, low frequency yoga, guided walking, and health education. In addition to examining the separate yoga interventions, a pooled yoga intervention is considered for comparison to guided walking and health education. Participant retention, adherence, and vitals were monitored at each intervention session. Participants were also scheduled for four clinic visits throughout the study where blood panels, health behavior, and medication surveys were administered. Results: Of the 375 participants recruited, 31.7% did not complete the study. At baseline, in both the guided walking group and the high frequency yoga group, there were significant differences between those who completed the study and those who did not. Although intervention retention in the pooled yoga program (78.3%) was higher compared to the walking (60%) and education programs (74.3%) (p = 0.007), differences in post-intervention retention was not significant. Median adherence rates for the pooled yoga program exceeded rates for guided walking and education with moderate frequency yoga out performing high and low frequency yoga. Conclusion: Study-defined retention success rates were not reached by all health promotion programs. However, retention and adherence rates for the pooled yoga program show that older African Americans are receptive to participating in yoga-based health promotion practices.

The Importance of Evaluating Health Disparities Research

Health disparity populations are socially disadvantaged, and the multiple levels of discrimination they often experience mean that their characteristics and attributes differ from those of the mainstream. Programs and policies targeted at reducing health disparities or improving minority health must consider these differences. Despite the importance of evaluating health disparities research to produce high-quality data that can guide decision-making, it is not yet a customary practice. Although health disparities evaluations incorporate the same scientific methods as all evaluations, they have unique components such as population characteristics, sociocultural context, and the lack of health disparity common indicators and metrics that must be considered in every phase of the research. This article describes evaluation strategies grouped into 3 components: formative (needs assessments and process), design and methodology (multilevel designs used in real-world settings), and summative (outcomes, impacts, and cost). Each section will describe the standards for each component, discuss the unique health disparity aspects, and provide strategies from the National Institute on Minority Health and Health Disparities Metrics and Measures Visioning Workshop (April 2016) to advance the evaluation of health disparities research.

"We Are Here to Assist All Individuals Who Need Hospice Services": Hospices' Perspectives on Improving Access and Inclusion for Racial/Ethnic Minorities

Background: Racial/ethnic minority populations in the United States are less likely to utilize hospice services nearing their end of life, potentially diminishing their quality of care while also increasing medical costs. Objective: Explore the minority hospice utilization gap from the hospice perspective by examining perceived barriers and facilitators as well as practices and policies. Method: Qualitative surveys were conducted with 41 hospices across the United States. Qualitative data analysis included performing a limited content analysis, including the identification of themes and representative quotations. Results: Commonly reported barriers to hospice care for racial/ethnic minorities included culture/beliefs, mistrust of the medical system, and language barriers. A major theme pertaining to successful minority hospice enrollment was an inclusive culture that provided language services, staff cultural training, and a diverse staff. Another major theme was the importance of community outreach activities that extended beyond the medical community and forming relationships with churches, racial/ethnic minority community leaders, and Native American reservations. Conclusion: The importance of incorporating a culture of inclusivity by forming committees, providing language services, and offering culturally competent care emerged in this qualitative study. Building strong external relationships with community groups such as churches is a strategy used to increase racial/ethnic minority utilization of hospice.

Influence of race and geographic setting on the management of gastric adenocarcinoma

BACKGROUND AND OBJECTIVES

Conflicting evidence indicates that both race and geographic setting may influence the management of malignancies such as gastric adenocarcinoma (GAC).

METHODS

We designed a retrospective cohort study utilizing data from the Surveillance, Epidemiology, and End Results program to identify patients with resectable GAC (N = 15 991). Exposures of interest were race and geographic region of diagnosis (West [WE], Midwest [MW], South [SO], or Northeast [NE]). Endpoints included: (1) recommendation against surgery and (2) gastric adenocarcinoma-specific survival (GACSS). Multivariable logistic and Cox regression models were used to identify pertinent associations.

RESULTS

A total of 15 991 patients were included (2007-2015). In adjusted analysis, African American individuals more frequently received a recommendation against surgical resection than White (adjusted odds ratio [aOR] = 0.86; 95% confidence interval [CI], 0.76-0.98), Asian American (aOR = 0.55; 95% CI, 0.46-0.65), and American Indian (aOR = 0.50; 95% CI, 0.31-0.82) individuals. In addition to race-based discrepancies, there was a significant association between geography and management: individuals diagnosed with GAC in the SO were more likely to receive a recommendation against surgery (odds ratio = 1.35; 95% CI, 1.23-1.49) and exhibited poorer GACSS as compared with those in the WE, MW, or NE regions.

CONCLUSIONS

Race and geographic region of diagnosis affect treatment recommendations and GACSS among individuals with resectable tumors. African Americans with resectable cancers are more likely to receive a recommendation against surgery than individuals of other racial groups.

Eliminating Racial/Ethnic Disparities in AIDS Clinical Trials in the United States: A Qualitative Exploration of an Efficacious Social/Behavioral Intervention

BACKGROUND

African American/Black and Hispanic persons living with HIV (AABH-PLWH) are under-represented in AIDS clinical trials (ACTs) in the United States. Barriers AABH-PLWH experience to ACTs are multi-faceted, including distrust of medical research, low levels of knowledge, unsupportive social norms, lack of referral, and challenges navigating ACT systems. In past research we found a multi-component peer-driven intervention was efficacious in boosting rates of screening for/enrollment into ACTs. The present qualitative study seeks to understand AABH-PLWH's perspectives on which specific intervention features or components had utility. Interventions features explored included structural elements (e.g., small group sessions, individual sessions on the ACT research unit); approaches (e.g., Motivational Interviewing); and specific components (e.g., small-group discussion of historical and cultural factors reducing participation among AABH-PLWH).

METHODS

A total of 37 AABH-PLWH (mean age 50.6 years, SD=7.5 years; 48.6% female; 62.2% African American/Black, 27.0% Hispanic) were purposively selected from a larger study for in-depth interviews, which were audio-recorded, transcribed verbatim, and analyzed using systematic content analysis.

RESULTS

We found the intervention improved knowledge and positive attitudes toward ACTs, and triggered social-level facilitators such as altruism and more positive social norms. Discussions of cultural/historical barriers to ACTs associated with race/ethnicity had utility. Holding a session on the ACT research unit reduced fear and increased motivation. Results highlighted the value of Motivational Interviewing, and several components were perceived as less useful (e.g., involving social network members in ACT decisions).

CONCLUSION

Findings can inform future intervention designs to address racial/ethnic disparities in ACTs and have implications for trials of other conditions where racial/ethnic disparities persist.

Collaborative development of clinical trials education programs for African-American community-based organizations

This paper describes the use of a unique "Learning and Feedbackˮ approach to customize cancer clinical trials education programs for Community Bridges, a peer training intervention designed for African-American communities in North Carolina. Generic community education modules were demonstrated with key community leaders who were designated as trainers. Quantitative and qualitative assessments were provided on understanding of content, comfort with material, and cultural relevance. The generic materials were adapted into three revised modules, all featuring key messages about cancer clinical trials, discussion regarding distrust of medical research, common misconceptions about trials, patient protections, and a call to action to prompt increased inquiry about locally available trials. The revised modules were then used as part of a train-the-trainer program with 12 African-American community leaders. ENACCT's use of the Learning and Feedback process is an innovative method for culturally adapting clinical trials education.

Five principles for effective cancer clinical trial education within the community setting

Participation in cancer clinical trials (CCTs) is a key measure for delivery of quality cancer care. Yet, adult cancer patient participation in CCTs remains at about 3%, and participation rates are even lower among ethnic and racial minorities and the medically underserved. Social justice demands better representation of all populations in CCTs to ensure equal access to clinical trials and to ensure greater generalizability of trial results. Using a conceptual framework, this paper outlines a set of guiding principles deemed essential for effective and ethical implementation of community-based education in CCTs. Also described are examples of interventions related to this framework that have been used to overcome key barriers to trial enrollment among underserved populations. Application of the key principles, combined with ongoing engagement of cancer care institutions, suggests promise in enhancing trial participation.

Description of an efficacious behavioral peer-driven intervention to reduce racial/ethnic disparities in AIDS clinical trials

AIDS clinical trials (ACTs) are critical to the development of new treatments for HIV infection. However, people of color living with HIV/AIDS are involved in ACTs at disproportionally low rates, with African-Americans experiencing the greatest under-representation. In this article, we describe the core elements and key characteristics of a highly efficacious multi-component peer-driven intervention (PDI) designed to increase rates of screening for and enrollment into ACTs among African-American and Latino/Hispanic individuals, by addressing the main complex, multi-level barriers they experience to ACTs. We discuss the process of developing the intervention, the theoretical models guiding its delivery format and content, and provide an overview of the intervention's components. We then use brief case studies to illustrate a number of key issues that may arise during intervention implementation. Finally, we describe lessons learned and provide recommendations for the PDI's uptake in clinical and clinical trials settings.

Recruitment and retention of participants in a pragmatic randomized intervention trial at three community health clinics: results and lessons learned

Background

Obesity and hypertension and their associated health complications disproportionately affect communities of color and people of lower socioeconomic status. Recruitment and retention of these populations in research trials, and retention in weight loss trials has been an ongoing challenge.

Methods

Be Fit, Be Well was a pragmatic randomized weight loss and hypertension management trial of patients attending one of three community health centers in Boston, Massachusetts. Participants were asked to complete follow-up assessments every 6-months for two years. We describe challenges encountered and strategies implemented to recruit and retain trial participants over the 24-month intervention. We also identify baseline participant characteristics associated with retention status. Retention strategies included financial incentives, contact between assessment visits, building relationships with health center primary care providers (PCPs) and staff, and putting participant convenience first.

Results

Active refusal rates were low with 130 of 2,631 patients refusing participation (4.9%). Of 474 eligible persons completing telephone screening, 365 (77.0%) completed their baseline visit and were randomized into the study. The study population was predominantly non-Hispanic Black (71.2%), female (68.5%) and reported annual household income of less than $35,000 (70.1%). Recruitment strategies included use of passive approval of potential participants by PCPs, use of part-time staff, and outsourcing calls to a call center. A total of 314 (86.0%) people completed the 24-month visit. Retention levels varied across study visits and intervention condition. Most participants completed three or more visits (69.6%), with 205 (56.2%) completing all four. At 24-months, lower retention was observed for males and the intervention condition. Retention strategies included building strong relationships with clinic staff, flexibility in overcoming participant barriers through use of taxi vouchers, night and weekend appointments, and keeping participants engaged via newsletters and social gatherings.

Conclusion

We were able to retain 86.0% of participants at 24-months. Recruitment and retention of high percentages of racial/ethnic minorities and lower income samples is possible with planning, coordination with a trusted community setting and staff (e.g. community health centers and RAs), adaptability and building strong relationships.

The Experience of Screening for HIV/AIDS Medical Studies among African-American/Black and Latino/Hispanic Persons Living with HIV/AIDS: A Mixed-Methods Exploration

Objective

African-American/Black and Latino/Hispanic persons living with HIV/AIDS (i.e., “PLHA of color”) are under-represented in HIV/AIDS medical studies (HAMS). A crucial entry point into HAMS is screening, but PLHA of color face serious barriers to screening compared to Whites. Recently we evaluated a social/behavioral intervention that substantially increased rates of HAMS screening among PLHA of color. Yet very little is known about the actual screening experience for these under-represented subgroups. Thus, the objectives of the present study were to explore participants’ motivations for and experiences of HAMS screening.

Methods

A total of 186 participants in the larger study’s intervention arm were screened for HAMS, 35 of whom also participated in qualitative interviews. Participants engaged in a structured interview about the screening experience at 4- and 12- months post-baseline (14 items, Cronbach's α=0.72). Further, from a qualitative data set we purposively selected a set of three case studies to contextualize and enrich quantitative findings on screening experiences.

Results

The screening experience was overwhelmingly positive. Almost all participants reported being treated with dignity and respect, did not feel they were being treated like a “guinea pig,” and experienced a high level of trust in the setting and the screener, with no gender or racial/ethnic differences, and no differences based on whether participants were found eligible for HAMS during screening. A number of areas where screening could be improved were also identified.

Conclusions

Despite the complex barriers PLHA of color experience to screening for HAMS, the experience of screening was positive. Moreover, HAMS screening experiences were positive regardless of gender, race/ethnicity, or HAMS eligibility. HAMS screening can therefore be a productive learning experience that may reduce patient concerns about participating in HAMS. As such, fostering screening among PLHA of color can be an important component of reducing racial/ethnic disparities in HAMS.

Participant-Centric Initiatives: Tools to Facilitate Engagement In Research

Clinical genomic research faces increasing challenges in establishing participant privacy and consent processes that facilitate meaningful choice and communication capacity for longitudinal and secondary research uses. There are an evolving range of participant-centric initiatives that combine web-based informatics tools with new models of engagement and research collaboration. These emerging initiatives may become valuable approaches to support large-scale and longitudinal research studies. We highlight and discuss four types of emerging initiatives for engaging and sustaining participation in research.

A study of racial/ethnic differences in treatment preferences among lupus patients

Objectives. To determine whether there are racial/ethnic differences in the willingness of SLE patients to receive CYC or participate in clinical trials, and whether demographic, psychosocial and clinical characteristics contribute to these differences.

Methods. Data from 120 African-American and 62 white lupus patients were evaluated. Structured telephone interviews were conducted to determine treatment preferences, as well as to study characteristics and beliefs that may affect these preferences. Data were analysed using serial hierarchical multivariate logistic regression and deviances were calculated from a saturated model.

Results. Compared with their white counterparts, African-American SLE patients expressed less willingness to receive CYC (67.0% vs 84.9%, P = 0.02) if their lupus worsened. This racial/ethnic difference remained significant after adjusting for socioeconomic and psychosocial variables. Logistic regression analysis showed that African-American race [odds ratio (OR) 0.29, 95% CI 0.10, 0.80], physician trust (OR 1.05, 95% CI 1.00, 1.12) and perception of treatment effectiveness (OR 1.40, 95% CI 1.22, 1.61) were the most significant determinants of willingness to receive CYC. A trend in difference by race/ethnicity was also observed in willingness to participate in a clinical trial, but this difference was not significant.

Conclusion. This study demonstrated reduced likelihood of accepting CYC in African-American lupus patients compared with white lupus patients. This racial/ethnic variation was associated with belief in medication effectiveness and trust in the medical provider, suggesting that education about therapy and improved trust can influence decision-making among SLE patients.

Recruitment of asthmatic ethnic minorities into a methacholine research study: factors influencing participation

BACKGROUND

How to recruit minority participants into research studies has been an issue since 1993, when NIH funding guidelines required minorities to be included as research participants.

OBJECTIVE

The purpose of this analysis was to determine what factors affected recruitment of asthmatic minorities into a large bronchoconstrictor study involving African-Americans, Hispanics/Mexican Americans, Asian/Pacific Islanders, and whites with mild asthma (forced expiratory volume in the first second of expiration > or = 70%).

METHODS

Ethnic minorities were recruited for 3 years. Recruitment strategies included physician and clinic referrals, newspaper ads, posters in health care settings, asthma databases, and electronic resources.

FINDINGS

After 3 years, the total number of referrals was 650, with 50 from medical doctor clinic settings and 600 from all of the other resources. The inclusion/exclusion criteria were clearly listed, but only 64.5% (419/650) of respondents met inclusion criteria. Of these, only 31.9% (134/419) [corrected] met pulmonary function testing criteria. Only 5, or 1% of the 50 medical doctor clinic referrals met inclusion criteria--1 participated. A total of 106, or 82.8%, completed all of the study procedures; for 87.7% of participants this was their first research experience. Hispanics/Mexican Americans accounted for only 14.8% of the total recruitment responses.

CONCLUSION

We believe our recruitment strategies did encourage ethnic minorities to participate, but the inclusion criteria of a positive methacholine response proved to be a study enrollment barrier.

The effect of peer-driven intervention on rates of screening for AIDS clinical trials among African Americans and Hispanics

OBJECTIVES

We examined the efficacy of a peer-driven intervention to increase rates of screening for AIDS clinical trials among African Americans and Hispanics living with HIV/AIDS.

METHODS

We used a randomized controlled trial design to examine the efficacy of peer-driven intervention (6 hours of structured sessions and the opportunity to educate 3 peers) compared with a time-matched control intervention. Participants were recruited using respondent-driven sampling (n = 342; 43.9% female; 64.9% African American, 26.6% Hispanic). Most participants (93.3%) completed intervention sessions and 64.9% recruited or educated peers. Baseline and post-baseline interviews (94.4% completed) were computer-assisted. A mixed model was used to examine intervention effects on screening.

RESULTS

Screening was much more likely in the peer-driven intervention than in the control arm (adjusted odds ratio [AOR] = 55.0; z = 5.49, P < .001); about half of the participants in the intervention arm (46.0%) were screened compared with 1.6% of controls. The experience of recruiting and educating each peer also increased screening odds among those who were themselves recruited and educated by peers (AOR = 1.4; z = 2.06, P < .05).

CONCLUSIONS

Peer-driven intervention was highly efficacious in increasing AIDS clinical trial screening rates among African Americans and Hispanics living with HIV/AIDS.

Research ethics I: Responsible conduct of research (RCR)--historical and contemporary issues pertaining to human and animal experimentation

PURPOSE

In this series of articles--Research Ethics I, Research Ethics II, and Research Ethics III--the authors provide a comprehensive review of the 9 core domains for the responsible conduct of research (RCR) as articulated by the Office of Research Integrity. In Research Ethics I, they present a historical overview of the evolution of RCR in the United States then examine the evolution of human and animal experimentation from the birth of scientific medicine through World War II to the present day.

METHOD

They relied on authoritative documents, both historical and contemporary, insightful commentary, and empirical research in order to identify current issues and controversies of potential interest to both faculty and students.

CONCLUSIONS

The authors have written this article from a historical perspective because they think all readers interested in RCR should appreciate how the history of science and all the good--and harm--it has produced can inform how researchers practice responsible research in the 21st century and beyond.

CONCLUSIONS

The authors close by urging readers to stay abreast of the manifold ethics issues facing today's community of scientists, policymakers, and research institutions, and to adhere to best practices as they evolve.

Trust in physicians and racial disparities in HIV care

Mistrust among African Americans is often considered a potential source of racial disparities in HIV care. We sought to determine whether greater trust in one's provider among African-American patients mitigates racial disparities. We analyzed data from 1,104 African-American and 201 white patients participating in a cohort study at an urban, academic HIV clinic between 2005 and 2008. African Americans expressed lower levels of trust in their providers than did white patients (8.9 vs. 9.4 on a 0-10 scale; p < 0.001). African Americans were also less likely than whites to be receiving antiretroviral therapy (ART) when eligible (85% vs. 92%; p = 0.02), to report complete ART adherence over the prior 3 days (83% vs. 89%; p = 0.005), and to have a suppressed viral load (40% vs. 47%; p = 0.04). Trust in one's provider was not associated with receiving ART or with viral suppression but was significantly associated with adherence. African Americans who expressed less than complete trust in their providers (0-9 of 10) had lower ART adherence than did whites (adjusted OR, 0.40; 95% CI, 0.25-0.66). For African Americans who expressed complete trust in their providers (10 of 10), the racial disparity in adherence was less prominent but still substantial (adjusted OR, 0.59; 95% CI, 0.36-0.95). Trust did not affect disparities in receipt of ART or viral suppression. Our findings suggest that enhancing trust in patient-provider relationships for African-American patients may help reduce disparities in ART adherence and the outcomes associated with improved adherence.

An exploratory behavioral intervention trial to improve rates of screening for AIDS clinical trials among racial/ethnic minority and female persons living with HIV/AIDS

Individuals from racial/ethnic minority backgrounds and women have not been proportionately represented in AIDS clinical trials (ACTs). There have been few intervention efforts to eliminate this health disparity. This paper reports on a brief behavioral intervention to increase rates of screening for ACTs in these groups. The study was exploratory and used a single-group pre/posttest design. A total of 580 persons living with HIV/AIDS (PLHA) were recruited (39% female; 56% African-American, 32% Latino/Hispanic). The intervention was efficacious: 25% attended screening. We identified the primary junctures where PLHA are lost in the screening process. Both group intervention sessions and an individual contact were associated with screening. Findings provide preliminary support for the intervention's efficacy and the utility of combining group and individual intervention formats. Interventions of greater duration and intensity, and which address multiple levels of influence (e.g., social, structural), may be needed to increase screening rates further.

Routine opt-out HIV testing strategies in a female jail setting: a prospective controlled trial

Background

Ten million Americans enter jails annually. The objective was to evaluate new CDC guidelines for routine opt-out HIV testing and examine the optimal time to implement routine opt-out HIV testing among newly incarcerated jail detainees.

Methods

This prospective, controlled trial of routine opt-out HIV testing was conducted among 323 newly incarcerated female inmates in Connecticut's only women's jail. 323 sequential entrants to the women's jail over a five week period in August and September 2007 were assigned to be offered routine opt-out HIV testing at one of three points after incarceration: immediate (same day, n = 108), early (next day, n = 108), or delayed (7 days, n = 107). The primary outcome was the proportion of women in each group consenting to testing.

Results

Routine opt-out HIV testing was significantly highest (73%) among the early testing group compared to 55% for immediate and 50% for 7 days post-entry groups. Other factors significantly (p = 0.01) associated with being HIV tested were younger age and low likelihood of early release from jail based on bond value or type of charge for which women were arrested.

Conclusions

In this correctional facility, routine opt-out HIV testing in a jail setting was feasible, with highest rates of testing if performed the day after incarceration. Lower testing rates were seen with immediate testing, where there is a high prevalence of inability or unwillingness to test, and with delayed testing, where attrition from jail increases with each passing day.

Proband race/ethnicity affects pedigree completion rate in a genetic study of ischemic stroke

BACKGROUND

A recent meta-analysis suggested that racial/ethnic status is not a major determinant of willingness to participate in observational studies or treatment trials. However, little is known about the predictors of enrollment in family-based observational genetic studies. We tested the hypothesis that proband race/ethnicity is a significant predictor of enrolling a pedigree.

METHODS

Univariable and multivariable logistic regression modeling was used to determine proband characteristics that predict DNA donation from both members of an affected sibling pair. A total of 619 adult male and female probands with first-time or recurrent ischemic stroke and a positive sibling history of stroke enrolled across 53 hospitals and clinics in the United States and Canada into the Siblings with Ischemic Stroke Study, a family-based prospective genomics study.

RESULTS

In univariable analysis, probands with siblings who agreed to a blood draw for DNA analyses were more likely to be male and less likely to be nonwhite. In multivariable analysis, only race/ethnicity was significantly associated with likelihood of a proband's having a sibling who agreed to a blood draw.

CONCLUSIONS

Contrary to observational studies that are not family based, the willingness of family members to participate in observational genetics studies may be influenced by race/ethnicity. This result reinforces the need for improving methods for recruiting diverse populations into genetic studies of stroke.

Ethnography and the generation of trust in breastfeeding disparities research

There are persistent racial/ethnic disparities in breastfeeding rates in the United States, and research is needed to examine underlying psychosocial, economic, and cultural factors. Research into health disparities is impeded by problems of distrust. This methods-focused article describes how an ethnographic approach can be used to generate trust while obtaining contextually detailed data. Examples are provided from an ethnography of infant feeding decisions among low-income, Black women. Trust-generating strategies included respectful entry into the field, recognizing and decreasing differences in power, sensitivity to time and timing, and a relational approach.
