Assessing research participants' perceptions of their clinical research experiences

Feasibility of BrainSTORM, a Traumatic Brain Injury Transitional Care Intervention

OBJECTIVE

To investigate the feasibility, acceptability, and clinical outcome measures of a transitional care intervention for patients with traumatic brain injury (TBI) and their family caregivers.

SETTING

Inpatient and outpatient rehabilitation at a level I trauma center in the Southeastern United States.

PARTICIPANTS

Patients (ages 18-75) diagnosed with moderate to severe TBI, receiving rehabilitation, and their family caregivers.

DESIGN

Quasi-experimental, single-arm, single-center feasibility study with pre- and post-test design. Participants completed a 4-month transitional care program involving monthly education and social support.

MAIN MEASURES

Feasibility of enrollment, data collection, intervention completion rates, and intervention acceptability. Clinical outcome measures included patient quality of life (QOL) (12-Item Short Form Health Survey (SF-12), primary outcome) and patient and caregiver self-efficacy (Self-Efficacy for Management of Chronic Conditions Scale).

RESULTS

Eleven dyads and 1 monad enrolled (N = 23, 12 patients, 11 caregivers). All completed baseline data; 91.3% (n = 21, 11 patients, 10 caregivers) completed 2-month (intervention midpoint) data; and 86% (n = 20, 11 patients, 9 caregivers) completed 4-month (intervention endpoint) data. The intervention completion rate was 91.67%. Participants engaged in a mean of 2.17 (SD = 1.34) monthly educational webinars and 2.42 (SD = 1.51) social support groups during the intervention period. Approximately 70% of participants (n = 16, 9 patients, 7 caregivers) completed acceptability data, indicating positive intervention experiences (patients: mean 9.44/10 [SD = 1.01]; caregivers: mean 9.57/10 [SD = 0.79]). Patient QOL scores did not statistically improve over time; however, patient self-efficacy scores did statistically significantly improve from baseline (mean = 7.03, SD = 1.53; P = .0197) to intervention end point (4 months) (mean = 8.35, SD = 1.71).

CONCLUSION

Brain Injury Support To Optimize Recovering Minds (BrainSTORM) is a promising new TBI transitional care intervention that has potential to enhance care standards for patients with TBI and their family caregivers. Further research is needed to determine its efficacy.

Patient, Relative and Staff Experiences of Clinical Trial Participation in Neurooncology: "Maybe You Can Also Show the Positive, No Matter How It Ends"

Purpose

There is a lack of evidence regarding how patients with malignant brain tumor and their relatives experience participation in neurooncological clinical trials. Similarly, insights from the perspective of trial staff caring for this group of patients are missing. This study aims to investigate patient, relative and trial staff experiences regarding participation in clinical neurooncological trials.

Methods

Within a qualitative exploratory study, 29 semi-structured interviews with brain tumor patients, relatives and trial staff were conducted and analyzed using reflexive thematic analysis (RTA) by Braun and Clarke. A patient researcher and patient council were involved in data analysis and interpretation.

Results

Four themes were developed reflecting significant aspects of the trial experience: 1. "It all revolves around hope"; 2. "Trial participation: experiencing unique medical care"; 3. "Everyone's roles are changing"; 4. "Communication as a possible area of conflict". Experiencing trial participation and general medical treatment were found to be interconnected to such a degree that they were often not meaningfully distinguished by patients and relatives.

Conclusion

In addition to assessing traditional endpoints for patient outcomes, we recommend increased emphasis on investigating the impact of the "soft" components constituting trial participation. Due to the interconnectedness of medical treatment and trial participation, we recommend further investigation in comparison to experiences in regular care. A deeper understanding of trial participation is needed to inform improvements for patient experiences and staff satisfaction alongside medical and scientific progress.

"There was No Opportunity to Express Good or Bad": Perspectives From Patient Focus Groups on Patient Experience in Clinical Trials

To understand how patients perceive their experiences leading up to, during, and after a clinical trial, and the relationship these experiences had with future willingness to participate, we conducted 3 focus groups with patients who had prior clinical trial involvement (n  =  25). Discussion topics included clinical trial discovery, enrollment, communication, trust, patient-centricity, and future enrollment. Patient focus groups revealed a variety of motivations for enrolling in clinical trials (eg, altruism, efficacious treatment, curiosity, desperation, etc.). Patients learned about clinical trials through trusted sources (eg, primary care physicians, patient advocacy groups) and social media. Access and uncertainty about clinical trials were barriers to enrollment. Patient-centric communication and attention given to disease states and symptom severity were valued and made patients feel genuinely cared about. Post-trial follow up and being informed of trial results were inconsistently reported by patients. Critically, patients described frustration with an overall lack of patient experience measurement. Patients identified a need to measure experiences before, during, and after clinical trials and emphasized that doing so would facilitate patient trust and overall experience.

Empowering the Participant Voice (EPV): Design and implementation of collaborative infrastructure to collect research participant experience feedback at scale

Empowering the Participant Voice (EPV) is an NCATS-funded six-CTSA collaboration to develop, demonstrate, and disseminate a low-cost infrastructure for collecting timely feedback from research participants, fostering trust, and providing data for improving clinical translational research. EPV leverages the validated Research Participant Perception Survey (RPPS) and the popular REDCap electronic data-capture platform. This report describes the development of infrastructure designed to overcome identified institutional barriers to routinely collecting participant feedback using RPPS and demonstration use cases. Sites engaged local stakeholders iteratively, incorporating feedback about anticipated value and potential concerns into project design. The team defined common standards and operations, developed software, and produced a detailed planning and implementation Guide. By May 2023, 2,575 participants diverse in age, race, ethnicity, and sex had responded to approximately 13,850 survey invitations (18.6%); 29% of responses included free-text comments. EPV infrastructure enabled sites to routinely access local and multi-site research participant experience data on an interactive analytics dashboard. The EPV learning collaborative continues to test initiatives to improve survey reach and optimize infrastructure and process. Broad uptake of EPV will expand the evidence base, enable hypothesis generation, and drive research-on-research locally and nationally to enhance the clinical research enterprise.

Community Engagement Strategies for Underrepresented Racial and Ethnic Populations

The representation of racial and ethnic minority populations in clinical trials continues to be a challenge despite mandates, good intentions, and concerted efforts by funding agencies, regulatory bodies, and researchers to close the clinical trials gap. A lack of diversity in research results in both continued disparities and poorer health outcomes. It is thus imperative that investigators understand and effectively address the challenges of clinical trials participation by underrepresented populations. In this paper, we expound on best practices for participatory research by clearly defining the community, highlighting the importance of proper identification and engagement of strong community partners, and exploring patient- and provider-level barriers and facilitators that require consideration. A clearer understanding of the balance of power between researchers and community partners is needed for any approach that addresses clinical trials representation. Unintended biases in study design and methods may continue to prevent racial and ethnic minority participants from taking part, and significant organizational changes are necessary for efficient and transparent relationships. Comprehensive community engagement in research includes dissemination of clinical trial results within and in partnership with community partners. Through careful deliberation and honest reflection, investigators, institutions, and community partners can develop the tailored blueprints of research collaborations essential for true equity in clinical trials.

Qualitative interview study exploring the perspectives of pregnant women on participating in controlled human infection research in the UK

INTRODUCTION

Pregnant women have been historically excluded from interventional research. While recent efforts have been made to improve their involvement, there remains a disparity in the evidence base for treatments available to pregnant women compared with the non-pregnant population. A significant barrier to the enrolment of pregnant women within research is risk perception and a poor understanding of decision-making in this population.

OBJECTIVE

Assess the risk perception and influences on decision-making in pregnant women, when considering whether to enrol in a hypothetical interventional research study.

DESIGN

Semistructured interviews were undertaken, and thematic analysis was undertaken of participant responses.

PARTICIPANTS

Twelve pregnant women were enrolled from an antenatal outpatient clinic.

RESULTS

Participants were unanimously positive about enrolling in the proposed hypothetical interventional study. Risk perception was influenced by potential risks to their fetus and their previous experiences of healthcare and research. Participants found the uncertainty in quantifying risk for new research interventions challenging. They were motivated to enrol in research by altruism and found less invasive research interventions more tolerable.

CONCLUSION

It is vital to understand how pregnant women balance the perceived risks and benefits of interventional research. This may help clinicians and scientists better communicate risk to pregnant women and address the ongoing under-representation of pregnant women in interventional research.

Children's satisfaction with a comprehensive study program-Results from the LIFE Child cohort study

BACKGROUND

Research participants' satisfaction is a topic of great interest, especially in the context of longitudinal studies. Evaluation also represents an important component of quality management in the health care system. Adult studies found that personal characteristics, e.g., age, sex, ethnicity, and SES, can influence satisfaction with health care or study participation. Studies on paediatric participants are sparse.

OBJECTIVES

To examine how children rated the study day of a cohort study and how these ratings were associated with sociodemographic and socioeconomic characteristics and retention in the context of a large cohort study.

METHODS

Analyses were performed on 4- to 17-year-old participants of the German longitudinal cohort study LIFE Child (n = 2033). To assess the associations between overall satisfaction (high versus low/middle) and age, sex, body-mass index, socioecomonic status, and participation in a follow-up visit, we applied logistic mixed-effects models.

RESULTS

Participants' overall satisfaction with the LIFE Child study day was high ("very good": 67.8%). Overall satisfaction was higher in 7-9 years olds (odds ratio [OR] 2.00, 95% confidence interval [CI 1.51, 2.66) and 10-12 years olds (OR 1.51, 95% CI 1.16, 1.98) than in 4-6 years olds and 13-17 years olds. Children with obesity were less likely to participate in a follow-up visit (OR 0.56, 95% CI 0.39, 0.78). Children reporting high overall satisfaction at the first study visit completed a follow-up visit more frequently (OR 1.32, 95% CI 1.05,1.67).

CONCLUSIONS

A high level of satisfaction increased participants' attendance at a follow-up visit. Our results might be helpful for adapting the study program to the participants' needs in order to maximise retention and minimise attrition rates.

Participant Experience with Protocol Research Kidney Biopsies in the Kidney Precision Medicine Project

BACKGROUND

Kidney biopsies are procedures commonly performed in clinical nephrology and are increasingly used in research. In this study we aimed to evaluate the experiences of participants who underwent research kidney biopsies in the Kidney Precision Medicine Project (KPMP).

METHODS

KPMP research participants with acute kidney injury (AKI) or chronic kidney disease (CKD) were enrolled at nine recruitment sites in the United States between September 2019 to January 2023. At 28 days post-biopsy, participants were invited to complete a survey to share their experiences, including: motivation to participate in research; comprehension of informed consent; pain and anxiety during and after the biopsy procedure; overall satisfaction with KPMP participation; and impact of the study on their lives. The survey was developed in collaboration with the KPMP Community Engagement Committee and the Institute of Translational Health Sciences at the University of Washington.

RESULTS

111 participants completed the survey, 23 enrolled for AKI and 88 for CKD. Median age was 61 (IQR 48-67) years, 43% were women, 28% were Black, and 18% were of Hispanic ethnicity. Survey respondents most commonly joined KPMP to help future patients (59%). The consent form was understood by 99% and 97% recognized their important role in the study. Pain during the biopsy was reported by 50%, at a median level of 1 (IQR 0-3) on a 0-10 scale. Anxiety during the biopsy was described by 64% at a median level of 3 (IQR 1-5) on a 0-10 scale. More than half conveyed that KPMP participation impacted their diet, physical activity, and how they think about kidney disease.

CONCLUSIONS

KPMP survey respondents were most commonly motivated to participate in research protocol kidney biopsies by altruism, with excellent understanding of the informed consent process.

Changing patient preferences toward better trial recruitment: an ethical analysis

While randomized controlled trials are essential to health research, many of these trials fail to recruit enough participants. Approaching recruitment through the lens of behavioral science can help trialists to understand influences on the decision to participate and use them to increase recruitment. Although this approach is promising, the use of behavioral influences during recruitment is in tension with the ethical principle of respect for persons, as at least some of these influences could be used to manipulate potential participants. In this paper, we examine this tension by discussing two types of behavioral influences: one example involves physician recommendations, and the other involves framing of information to exploit cognitive biases. We argue that despite the apparent tension with ethical principles, influencing trial participants through behavior change strategies can be ethically acceptable. However, we argue that trialists have a positive obligation to analyze their recruitment strategies for behavioral influences and disclose these upfront to the research ethics committee. But we also acknowledge that since neither trialists nor ethics committees are presently well equipped to perform these analyses, additional resources and guidance are needed. We close by outlining a path toward the development of such guidance.

Gathering the Stakeholder's Perspective: Experiences and Opportunities in Rare Genetic Disease Research

BACKGROUND

Research participant feedback is rarely collected; therefore, investigators have limited understanding regarding stakeholders' (affected individuals/caregivers) motivation to participate. Members of the Genes to Mental Health Network (G2MH) surveyed stakeholders affected by copy number variants (CNVs) regarding perceived incentives for study participation, opinions concerning research priorities, and the necessity for future funding. Respondents were also asked about feelings of preparedness, research burden, and satisfaction with research study participation.

METHODS

Modified validated surveys were used to assess stakeholders´ views across three domains: (1) Research Study Enrollment, Retainment, Withdrawal, and Future Participation; (2) Overall Research Experience, Burden, and Preparedness; (3) Research Priorities and Obstacles. Top box score analyses were performed.

RESULTS

A total of 704 stakeholders´ responded from 29 countries representing 55 CNVs. The top reasons for initial participation in the research included reasons related to education and altruism. The top reasons for leaving a research study included treatment risks and side effects. The importance of sharing research findings and laboratory results with stakeholders was underscored by participants. Most stakeholders reported positive research experiences.

CONCLUSIONS

This study provides important insight into how individuals and families affected with a rare CNV feel toward research participation and their overall experience in rare disease research. There are clear targets for areas of improvement for study teams, although many stakeholders reported positive research experiences. Key findings from this international survey may help advance collaborative research and improve the experience of participants, investigators, and other stakeholders moving forward.

How do Hispanics/Latinos Perceive and Value the Return of Research Results?

Introduction: Interest in the return of research results has been increasing; however, little is known about how Hispanics/Latinos perceive and value receiving results. This study examined differences among Hispanics/Latinos by education and income in the experience and expectations about the return of research results, perceived value of specific types of information, and the least and most valuable specific information. Method: Retrospective observational design using a cross-sectional national survey sample of Hispanics/Latinos (n = 327). Results: Higher educational attainment was positively associated with the expectation to receive research results, likelihood to participate in research if given study findings, and likelihood to trust researchers if given results. Higher income was positively associated with the perceived value of getting results. Respondents with higher education specifically perceived greater value in information about how lifestyle and genetics affect their risk of disease, how genetics affect how they respond to medications, their ancestry, available clinical trials near them, and how to connect with other study participants. Respondents with higher income perceived greater value in information about how genetics affect their risk of disease and how they respond to medications. Conclusion: The findings offer important insights for planning research initiatives and for developing culturally targeted educational materials for Hispanics/Latinos.

Exit from Brain Device Research: A Modified Grounded Theory Study of Researcher Obligations and Participant Experiences

As clinical trials end, little is understood about how participants exiting from clinical trials approach decisions related to the removal or post-trial use of investigational brain implants, such as deep brain stimulation (DBS) devices. This empirical bioethics study examines how research participants experience the process of exit from research at the end of clinical trials of implanted neural devices. Using a modified grounded theory study design, we conducted semi-structured, in-depth interviews with 16 former research participants from clinical trials of DBS and responsive neurostimulation (RNS). Open-ended questions elicited motivations for joining the trial, understanding of study procedures at the time of initial informed consent, the process of exiting from research, and decisions about device removal or post-trial device use. Thematic analysis identified categories related to: limited preparedness for the end of research participation, straightforwardness of decisions to explant or keep the device, reconciling with the end of research participation, reconciling post-trial expectations, and achieving a sense of closure after exit from research. A preliminary theoretical model describes contextual factors influencing the process and experience of exit from research. Experiences of clinical trial participants should guide research practices to enhance the ethical design and conduct of clinical trials in DBS and other brain devices.

Understanding factors contributing to participant satisfaction in stroke walking recovery clinical trials

Background

Individuals with stroke face a distinct set of challenges, barriers and facilitators that need to be understood to streamline efficacy of stroke clinical trials and improve participant retention. Few long-term stroke rehabilitation trials have evaluated participant perception of their laboratory experience.

Methods

We collected data regarding trial satisfaction from 33 individuals with stroke who participated in 12 sessions of treadmill training which included pre, post and follow-up non-invasive brain stimulation and clinical assessments. We evaluated factors such as overall trial satisfaction, burden of testing, perceived benefits, perceived barriers, and perceived support using a participant satisfaction questionnaire (PSQ) that assessed participants' overall trial experience.

Results

97% of our participants found participating in the study to be rewarding and would recommend it to other persons with stroke. Transcranial magnetic stimulation (TMS) testing was found to be the major perceived burden of participation while travelling to the lab was found to be the major perceived barrier to participation. Significant correlations were found between various items of the PSQ and clinical assessments.

Conclusions

This study helped us get a preliminary perspective into the benefits and barriers faced by persons with stroke enrolled in a 4-week long clinical trial. We observed that participant satisfaction was driven by various factors including functional status, personal relevance to the research, perceptive physical and mental health improvements, interaction with research personnel, and ease of testing protocols.

Recruiting and retaining participants in three randomised controlled trials of psychological interventions conducted on acute psychiatric wards: top ten tips for success

BACKGROUND

It is essential to conduct randomised controlled trials of psychological interventions on acute psychiatric wards to build a robust evidence base for clinical practice.

AIMS

This paper aims to share strategies from three different in-patient trials that successfully recruited and retained participants, to disseminate good practice for the conduct of future trials in this challenging and complex clinical setting.

METHOD

We present strategies from three in-patient trials of psychological interventions: TULIPS (Talk, Understand, Listen for Inpatient Settings), amBITION (Brief Talking Therapies on Wards) and INSITE (Inpatient Suicide Intervention and Therapy Evaluation). All studies recruited participants from acute in-patient wards, initiated therapy within the in-patient setting and followed up on participants post-discharge.

RESULTS

We summarise our recommendations for good practice in the form of ten top tips for success, based on our collective experience of conducting trials on psychiatric wards. Key themes relate to the importance of relationships between the research team and clinical staff; good stakeholder involvement and getting early buy-in from the team; and adapting to the particular demands of the clinical setting.

CONCLUSIONS

Sharing good practice recommendations can help reduce research waste arising from poor recruitment and/or retention in future in-patient clinical trials.

The Clinical Utility of the Adolescent and Young Adult Psycho-Oncology Screening Tool (AYA-POST): Perspectives of AYA Cancer Patients and Healthcare Professionals

Objective

Routine psychosocial screening and assessment of people diagnosed with cancer are crucial to the timely detection of distress and provision of tailored supportive care; however, appropriate screening tools have been lacking for adolescents and young adults (AYAs), who have unique needs and experiences. One exception is the recently validated AYA Psycho-Oncology Screening Tool (AYA-POST) for use with young people aged 15–29 years, which comprises a distress thermometer and age-specific needs assessment. This study investigates the clinical utility of this measure, as well as the subsequent service responsiveness within the Australian Youth Cancer Services.

Method

In total, 118 AYAs and 29 healthcare professionals: (HCPs) completed surveys about the clinical utility of the AYA-POST; a subset of 30 AYAs completed a 3-month follow-up survey assessing service responsiveness. Descriptive statistics (frequencies/means) were computed for all items, with chi-square analyses used to explore whether perceived clinical utility varied with AYA age, AYA sex, HCP discipline or HCP length of time using the AYA-POST.

Results

Participants’ responses demonstrate high levels of satisfaction with the tool, evidencing its appropriateness, practicability and acceptability. Moreover, the AYA-POST was reported to facilitate communication about psychosocial needs and prompt referrals, indicating good service responsiveness. Ratings of clinical utility did not differ significantly between AYA and HCP groups.

Conclusion

This study demonstrates that the AYA-POST is an appropriate tool in the psychosocial screening of AYAs with cancer, facilitating the identification of distress and unique concerns in this population and valuable in triaging and tailoring care for young cancer patients.

A Video-Based Behavioral Intervention Associated with Improved HPV Knowledge and Intention to Vaccinate

The aim of this study was to design, develop, and evaluate the feasibility of a theory- and evidence-based intervention to improve human papillomavirus (HPV) and HPV vaccine knowledge and intention to vaccinate, among parent–daughter dyads. A theory- and evidence-based online behavioral intervention, “Is the HPV vaccine for me?”, was developed to improve HPV and HPV vaccine knowledge and intention to vaccinate. Knowledge, intention to vaccinate, and feasibility of the intervention were evaluated in a prospective, randomized, controlled feasibility trial. A total of 49 parent–daughter dyads completed the baseline knowledge assessment (n = 24 control, n = 25 intervention), and 35 dyads completed the knowledge assessment at week 2 (n = 17 control, n = 18 intervention). The intervention resulted in a statistically significant increase in HPV and HPV vaccine knowledge and intention to vaccinate. All intervention participants found the video interesting, while 96% found it useful. This intervention was found to be useful, effective, safe, and acceptable in this feasibility study.

Is staff consistency important to parents' satisfaction in a longitudinal study of children at risk for type 1 diabetes: the TEDDY study

BACKGROUND

Participants' study satisfaction is important for both compliance with study protocols and retention, but research on parent study satisfaction is rare. This study sought to identify factors associated with parent study satisfaction in The Environmental Determinants of Diabetes in the Young (TEDDY) study, a longitudinal, multinational (US, Finland, Germany, Sweden) study of children at risk for type 1 diabetes. The role of staff consistency to parent study satisfaction was a particular focus.

METHODS

Parent study satisfaction was measured by questionnaire at child-age 15 months (5579 mothers, 4942 fathers) and child-age four years (4010 mothers, 3411 fathers). Multiple linear regression analyses were used to identify sociodemographic factors, parental characteristics, and study variables associated with parent study satisfaction at both time points.

RESULTS

Parent study satisfaction was highest in Sweden and the US, compared to Finland. Parents who had an accurate perception of their child's type 1 diabetes risk and those who believed they can do something to prevent type 1 diabetes were more satisfied. More educated parents and those with higher depression scores had lower study satisfaction scores. After adjusting for these factors, greater study staff change frequency was associated with lower study satisfaction in European parents (mothers at child-age 15 months: - 0.30,95% Cl - 0.36, - 0.24, p < 0.001; mothers at child-age four years: -0.41, 95% Cl - 0.53, - 0.29, p < 0.001; fathers at child-age 15 months: -0.28, 95% Cl - 0.34, - 0.21, p < 0.001; fathers at child-age four years: -0.35, 95% Cl - 0.48, - 0.21, p < 0.001). Staff consistency was not associated with parent study satisfaction in the US. However, the number of staff changes was markedly higher in the US compared to Europe.

CONCLUSIONS

Sociodemographic factors, parental characteristics, and study-related variables were all related to parent study satisfaction. Those that are potentially modifiable are of particular interest as possible targets of future efforts to improve parent study satisfaction. Three such factors were identified: parent accuracy about the child's type 1 diabetes risk, parent beliefs that something can be done to reduce the child's risk, and study staff consistency. However, staff consistency was important only for European parents.

Methodological approaches for conducting follow-up research with clinical trial participants: a scoping review and expert interviews

Background

Evidence-based establishment and implementation of best principles, laws and ordinances that regulate clinical research depend on the consultation and involvement of trial participants. Yet, guidance on methodological approaches to obtain trial participants’ perspectives is currently missing. This scoping review therefore aimed at identifying, describing and evaluating research approaches to obtain trial participants’ feedback on their views and experiences.

Methods

We searched the electronic databases Medline and PsycInfo via Ovid and the Web of Science Core Collection. Clinical trials were included that involved adult participants that were conducted in selected high-income countries and that were published in peer-reviewed journals between 1985 and 2018. In addition, 29 expert interviews were conducted between March and May 2019.

Results

Out of 5994 identified records, 23 articles were included in this review. Twelve studies used a qualitative approach, 10 were quantitative and one study used a mixed-method design. More than 75% of all work was conducted in the USA and the UK. The scoping review and the expert interviews highlighted that recruitment of participants was generally done through direct contact by principal investigators and/or study nurses or through searches in de-identified patient databases. Authors used surveys, interviews or focus group discussions. The tools used were either based on existing validated ones or developed and verified de novo with the support of experts and/or patient representatives.

Conclusions

To our knowledge, this is the first methodological literature review of approaches to researching experiences of clinical trial participants where findings were triangulated with expert interviews. Covering a range of indications, trial phases and study settings, it demonstrates that clinical trial participant perspectives and experience is heavily under-researched. This casts doubt on the overall robustness of available insight into trial participants’ views and experiences. Our results demonstrate that the methodology for studying participant opinion, perception and experience should be adapted to the measure of interest and conform to the study population. Using valid patient experience data is the basis to evaluate existing legal and regulatory human subject research frameworks for their appropriateness from a patient perspective. Such an evaluation will be critical to empower research participants.

Methods-Motivational Interviewing Approach for Enhanced Retention and Attendance

INTRODUCTION

Suboptimal and differential participant engagement in randomized trials-including retention at primary outcome assessments and attendance at intervention sessions-undermines rigor, internal validity, and trial conclusions.

METHODS

First, this study describes Methods-Motivational Interviewing approach and strategies for implementation. This approach engages potential participants before randomization through interactive, prerequisite orientation sessions that illustrate the scientific rationale behind trial methods in accessible language and use motivational interviewing to diffuse ambivalence about participation. Then, this study examines the potential improvements in retention (proportion of participants assessed at follow-up visits) and attendance (e.g., mean percentage of intervention sessions attended, percentage of participants who attended 0 sessions) in 3 randomized weight-management trials that quickly added prerequisite orientations to their protocols following early signs of suboptimal or differential participant engagement (Supporting Health by Integrating Nutrition and Exercise [2009-2013, n=194]; Get Social [2016-2020, n=217]; GestationaL Weight Gain and Optimal Wellness [2014-2018, n=389]). Using a pre-post analytical design, adjusted estimates from regression models controlling for condition and assessment timepoint (analyses from 2020) are reported.

RESULTS

After adding prerequisite orientations, all 3 trials attained higher participant engagement. Retention at assessments was 11.4% and 17.3% higher (Get Social and Supporting Health by Integrating Nutrition and Exercise, respectively). Mean percentage of attendance at intervention sessions was 8.8% higher (GestationaL Weight Gain and Optimal Wellness), and 10.1% fewer participants attended 0 intervention sessions (Get Social). Descriptively, all the remaining retention and attendance outcomes were consistently higher but were nonsignificant. Across the trials, adding prerequisite orientations did not impact the proportion of eligible participants enrolled or the baseline demographics.

CONCLUSIONS

The Methods-Motivational Interviewing approach shows promise for increasing the rigor of randomized trials and is readily adaptable to in-person, webinar, and conference call formats.

TRIAL REGISTRATION

All 3 trials are registered at www.clinicaltrials.gov (Supporting Health by Integrating Nutrition and Exercise: NCT00960414; Get Social: NCT02646618; and GestationaL Weight Gain and Optimal Wellness: NCT02130232).

Recruiting Persons with Dementia and Caregivers in a Clinical Trial: Dyads Perceptions

Recruitment for dementia research is challenging and costly. Using Ajzen's Theory of Planned Behavior we explored attitudes, perceived norms, and perceived behavioral control of persons living with dementia (PLWD) and their caregivers who participated in one clinical trial to better understand factors that influence dyads' decisions to enroll. We conducted semi-structured telephone interviews with 12 PLWD and 9 caregivers and utilized directed content analysis. Categories connected with positive attitudes about study enrollment were personal desires of wanting to learn and in-person meetings with knowledgeable staff. Additionally, participants said the money always helps in terms of the financial incentive. Participants reported enrolling to support another person (perceived norm). Study requirements were thought to be easy (perceived behavioral control). Participants highlighted the importance of flexible scheduling and study tasks being completed at their home. Findings can inform future recruitment efforts and should be investigated as effective recruitment methods in other clinical trials.

Attitudes of Dilated Cardiomyopathy Patients and Investigators Toward Genomic Study Enrollment, Consent Process, and Return of Genetic Results

Precision medicine genetics study design requires large, diverse cohorts and thoughtful use of electronic technologies. Involving patients in research design may increase enrollment and engagement, thereby enabling a means to relevant patient outcomes in clinical practice. Few data, however, illustrate attitudes of patients with dilated cardiomyopathy (DCM) and their family members toward genetic study design. This study assessed attitudes of 16 enrolled patients and their family members (P/FM), and 18 investigators or researchers (I/R) of the ongoing DCM Precision Medicine Study during a conjoint patient and investigator meeting using structured, self‐administered surveys examining direct‐to‐participant enrollment and web‐based consent, return of genetic results, and other aspects of genetic study design. Survey respondents were half women and largely identified as white. Web‐based consent was supported by 93% of P/FM and 88% of I/R. Most respondents believed that return of genetic results would motivate study enrollment, but also indicated a desire to opt out. Ideal study design preferences included a 1‐hour visit per year, along with the ability to complete study aspects by telephone or web and possibility of prophylactic medication. This study supports partnership of patients and clinical researchers to inform research priorities and study design to attain the promise of precision medicine for DCM.

"It's being part of the big picture, even though you're a tiny jigsaw piece"-motivations and expectations of individuals participating in the Enroll-HD observational study

Predictive test guidelines for Huntington's disease (HD) recommend individuals are offered opportunities to participate in research regardless of test outcome. Consistent with most HD centres of excellence, the Manchester Centre for Genomic Medicine (MCGM) invites eligible individuals to participate in the observational study, Enroll-HD. Limited research has been conducted to date on the views of research participants and the possible impact of participation. The aim of this qualitative study was to explore the experiences of ten individuals taking part in the Enroll-HD study following pre-symptomatic testing for HD. Half of the individuals had tested positive for the HD mutation and the other half had tested negative. Participants were generally motivated to take part in the study by both personal and altruistic reasons. Overall, they were very positive about participation in Enroll-HD. Valuable aspects included good relationships with the research/clinical team, increased understanding of the condition, an enhanced self-image and a shared experience with affected parents. Issues for improvement to encourage participation included access to study site and more regular communication about study progress. Participants, while generally optimistic about research progress, were realistic about challenges.

Association Between Participant Contact Attempts and Reports of Being Bothered in a National, Longitudinal Cohort Study of ARDS Survivors

BACKGROUND

Participant retention is a major challenge in clinical research, especially in studies with multiple, longitudinal research assessments. Despite the importance of retention methods, there is little empirical research on how cohort retention efforts are perceived by study participants.

RESEARCH QUESTION

To evaluate the association between the number of attempts undertaken to contact participants for research assessments in a longitudinal cohort study and participants' feeling of being bothered regarding such contact attempts.

STUDY DESIGN AND METHODS

Secondary analysis of 315 ARDS survivors participating in a prospective study using comprehensive strategies for participant follow-up at 6 and 12 months that achieved > 95% participant retention. After completing a 242-question research assessment lasting 20 to 40 min, participants were surveyed for feedback.

RESULTS

At 6 and 12 months, only 5% and 8% of participants, respectively, reported being bothered "more than a little bit" by the study contact attempts, with an OR of 1.06 (95% CI, 1.02-1.10) for each contact attempt. Participants' mental health symptoms at follow-up assessment were not associated with reports of being bothered.

INTERPRETATION

Comprehensive cohort retention efforts can achieve > 95% retention rates in a national longitudinal study, with most participants reporting little or no bother by contact attempts. Despite a high frequency of mental health symptoms in this population, such symptoms were not associated with participant feedback regarding contact attempts. Careful training of research staff may be important in achieving such results.

Satisfaction and perceptions of research participants in clinical and translational studies: An urban multi-institution with CTSA

Purpose:

To examine research participants’ levels of satisfaction and perceptions and aid researchers to better engage research volunteers from all racial and ethnic populations in clinical trials. A participant satisfaction survey was developed that focused on three domains to reflect satisfaction with delivery of care, environment, and center operations. In addition, the survey contained open-ended questions to reflect overall experiences and perceptions. Two hundred and seventy-eight participants (55% African American and 29% non-Hispanic Whites) with an average age of 52 years completed the survey.

Results:

The results indicated that the majority of the participants rated their satisfaction very highly across all domains. Ninety percent stated they were very satisfied/satisfied or very strongly agreed/agreed in the three domains. Obtaining high-quality care/access to health care professionals (60%), learning more about their illness/disease (60%), and helping others (57%) were noted as important factors in choosing to participate in a trial. Regarding overall experience, majority of respondents stated that friendliness, expertise of staff, learning more about their disease, and contributing to science were important. Further, financial compensation was not a primary motivation for participation. A majority of participants stated that they would participate in future studies and would recommend a friend or a family member to participate in clinical trials.

Conclusions:

The findings indicate that the degree of satisfaction with the research staff and with the specific trial itself are important determinants for enrolling, completing a study, and for participating in future trials.

Identifying and responding to trial implementation challenges during multisite clinical trials

INTRODUCTION

The National Drug Abuse Treatment Clinical Trials Network (CTN) was initiated by the National Institute on Drug Abuse (NIDA) in 2000 with the aim of improving substance use treatment and reducing the time between the discovery of effective treatments and their implementation into clinical practice. While initial trials were conducted almost exclusively in specialty addiction treatment settings, the CTN began evolving strategically in 2010 to conduct research in general medical settings, including healthcare systems, primary care settings, emergency departments, and pharmacies, to broaden impact. The advantages of a research network like the CTN is not only the collective content expertise that investigators contribute to the network, but the collective experience gained by conducting studies in the network and then applying those lessons to future studies.

OBJECTIVE

To summarize trial implementation challenges encountered, and the process by which solutions were identified and implemented, within one of the last early-phase CTN Stage II behavioral intervention studies conducted in a specialty addiction treatment setting.

METHOD AND RESULTS

We describe the implementation of the CTN-0037 STimulant Reduction Intervention using Dosed Exercise (STRIDE) trial. Issues encountered during study implementation are categorized into four major areas, described in terms useful to future study teams: 1) study team infrastructure challenges, 2) participant- and site- level challenges, 3) intervention-related challenges, and 4) longitudinal study design challenges. Potential consequences of identified problems and the solutions developed to manage these problems are discussed within the context of these four areas. We propose how to extend these implementation lessons and apply them in other healthcare settings to expand the CTN.

CONCLUSIONS

Effective study management allows for flexible, collaborative solutions to expected and unexpected obstacles to study success. Implementation strategies derived from the first 15 to 20 years of CTN studies are a result of working with providers and participants, and the ongoing collaboration among CTN investigators and network staff. Timely identification and response to problems during study implementation are critical to the success of a trial, regardless of its design. We believe a collaborative approach to identifying and responding to study implementation challenges will increase the likelihood of successful adoption of relevant, efficacious interventions. As the CTN continues to expand, the wealth of successful trial implementation strategies developed during the first 20 years of the CTN need to be applied and adapted to studies in broader network settings, and considered in conjunction with more formalized implementation science processes that are currently available.

Motivations and Decision Making Processes of Men With X-linked Retinoschisis Considering Participation in an Ocular Gene Therapy Trial

PURPOSE

To describe the motivations, expectations, and other factors men with X-linked retinoschisis (XLRS) consider when making decisions to participate in an early phase ocular gene therapy clinical trial.

DESIGN

Qualitative interview study.

METHODS

Men with XLRS who were considering participation in a phase I/IIa ocular gene therapy clinical trial at the National Eye Institute were eligible for this study. Trial participants (n = 9) were interviewed prior to receiving the gene transfer and then at 3 and 12 months later. Trial participation decliners (n = 2) were interviewed at an initial visit and 12 months later. Those screened for the trial and found ineligible (n = 2) were interviewed at an initial visit only. Interviews were transcribed, coded, and analyzed thematically.

RESULTS

Interview participants described decision making factors as risk-benefit assessments, personal intuition, trust in the study team, and religious faith. Altruism and the potential for therapeutic benefit were the main motives for trial participation, whereas the uncertainty of risks and benefits was the reason 2 men declined participation. Although most participants hoped for direct benefit, no one expected to benefit. Almost all interview participants considered their decision straightforward and were satisfied with their decision when interviewed over time. Meaningful relationships with the study team and perceived secondary benefits to participation contributed to positive trial experiences.

CONCLUSIONS

Engaging prospective research participants in a discussion about their hopes, expectations, and personal factors provides a more complete understanding of patient decision making and may help support informed choices to participate in clinical trials for XLRS.

The Reasonable Person Standard for Research Disclosure: A Reasonable Addition to the Common Rule

The revised Common Rule adopts the reasonable person standard to guide research disclosure. Some members of the research community contend that the standard is confusing and ill-suited to the research oversight system. Yet the revised rule is not as radical as it might seem. During the 1970s, judges started using the standard to evaluate negligence claims brought by injured patients who said doctors had failed to obtain informed consent to the harmful procedures. In its influential Belmont Report, the National Commission recommended application of a "reasonable volunteer standard" to guide IRBs evaluating research disclosures. Evidence also suggests that IRBs often invoke the reasonable person standard in deliberations about consent forms. But past application of the standard has been informal and uneven. Robust application of the reasonable person standard will require researchers and IRBs to learn more about what ordinary people want and need to know about the studies they are invited to join. Input from people with personal experience as study participants could be particularly useful to this effort.

Facilitators and Barriers to Participating in a Randomized Controlled Trial of a Psychological Therapy for Substance Use

Research involving substance users with psychosis has high refusal and attrition rates. Understanding participants' experiences of research participation is therefore important. Twenty-two cannabis users with schizophrenia spectrum disorders were recruited. They were involved in a randomized controlled trial exploring the effectiveness of motivational interviewing plus cognitive behavioral therapy. Semistructured interviews were conducted, and their responses were analyzed using thematic analysis. Thematic analysis identified facilitators such as therapeutic benefit, knowledge about medical conditions, awareness of own drug habits, helping others, confidentiality, rapport with researchers, desiring social contact, and views of significant others. Barriers identified were cognitive challenge, amount of assessments, duration, and discussions about the past. Based on these insights, we recommend informing participants about clinical equipoise, confidentiality, and demands of the study; minimizing demands on participants; acknowledging participants' efforts; involving potential participants' significant others during recruitment; advertising research as an opportunity to help; and training researchers in building rapport.

Key Information in the New Common Rule: Can It Save Research Consent?

Informed consent in clinical research is widely regarded as broken, but essential nonetheless. The most recent attempt to reform it comes as part of the first revisions to the Common Rule since it became truly "common" in 1991. This change, the addition of a "key information" requirement for most consent forms, is intended to support and promote a reasoned decision-making process by potential subjects. The key information requirement is both promising and problematic. It is promising because it encourages clarity and honesty about research participation, creativity in information disclosure, and mutual learning through the investigator-subject relationship. It is problematic because those goals - which have remained aspirational since the beginning - may be difficult to achieve in what has become an excessively compliance-oriented regulatory regime.

Gestational weight gain and optimal wellness (GLOW): rationale and methods for a randomized controlled trial of a lifestyle intervention among pregnant women with overweight or obesity

BACKGROUND

Excess gestational weight gain (GWG) is common among women with overweight or obesity, increasing their risks for pregnancy complications, delivering a large infant, and postpartum weight retention. To date, only intensive interventions have had success and few interventions have been designed for implementation in healthcare settings.

METHODS

We describe the development, rationale, and methods of GLOW (GestationaL Weight Gain and Optimal Wellness), a randomized controlled trial evaluating the efficacy of a lifestyle intervention to prevent excess GWG among racially/ethnically diverse women with overweight or obesity in an integrated healthcare delivery system. Participants in Kaiser Permanente Northern California will be randomized, within 2 weeks of completing a study baseline clinic visit at 10 weeks' gestation, to either usual medical care or a multi-component pregnancy lifestyle intervention adapted from the Diabetes Prevention Program (target N = 400). Informed by focus groups with patients and designed to be feasible in a clinical setting, the intervention will include 13 weekly individual sessions (11 delivered by telephone) focused on behavior change for weight management, healthy eating, physical activity, and stress management. Outcomes will be assessed in women and their infants from randomization to 12 months postpartum. The primary outcome is GWG. Secondary outcomes include changes in diet and physical activity during pregnancy and infant birthweight. Exploratory outcomes include cardiometabolic profile assessed via pregnancy blood samples and cord blood samples; and postpartum weight retention and infant anthropometrics up to 12 months of age. The trial includes systematic approaches to enhance intervention fidelity, intervention adherence, and participant retention in trial assessments.

DISCUSSION

GLOW is among few trials targeting excess GWG among diverse women with overweight or obesity in a healthcare setting, with long-term maternal and infant outcomes assessed up to 12 months after delivery. This evaluation of a multi-component intervention is designed to produce generalizable results to inform potential adoption of the intervention in clinical settings.

Impact of survey length and compensation on validity, reliability, and sample characteristics for Ultrashort-, Short-, and Long-Research Participant Perception Surveys

INTRODUCTION

The validated Research Participant Perception Survey (RPPS-Long) elicits valuable data at modest response rates.

METHODS

To address this limitation, we developed shorter RPPS-Ultrashort and RPPS-Short versions, fielded them with the RPPS-Long to a random sample of a national research volunteer registry, and assessed response and completion rates, test/retest reliability, and demographics.

RESULTS

2228 eligible registry members received survey links. Response rates were 64% (RPPS-Ultrashort), 63% (RPPS-Short), and 51% (RPPS-Long), respectively (P<0.001). Completion rates were 63%, 54%, and 37%, respectively (p<0.001). All surveys were reliable with Cronbach's alpha = 0.81, 0.84, and 0.87, respectively. Retest reliability was highest for RPPS-Short (Kappa=0.85). Provision of compensation increased RPPS-Short completion rate from 54% to 71% (p<0.001). Compensated respondents were younger (p<0.001), with greater minority representation (p=0.03).

CONCLUSIONS

Shorter surveys were reliable and produced higher response and completion rates then long surveys. Compensation further increased completion rates and shifted sample age and race profiles.

Incentives for recruiting trainee participants in medical education research

INTRODUCTION

In the growing field of medical education research, participant recruitment can be challenging. Incentives, either tangible or intangible, may be offered to encourage participation. This study aimed to understand these incentives and explore the relationship between study quality and incentives in medical education research.

METHODS

We reviewed research studies examining medical trainees published in five major journals in 2008. Tangible and intangible incentives used in recruitment were extracted by two researchers. For each quantitative article, medical education research quality instrument (MERSQI) score was calculated and citation counts for all articles were compiled.

RESULTS

Of 215 included articles, 8% explicitly reported incentives. Tangible incentives (value range $15-$60 USD) were offered in 7.9% of studies. Intangible incentives were identified in 30% of studies but only one specifically discussed their use. Tangible incentives correlated with a higher MERSQI score (p < 0.001) and with citations (p < 0.001).

CONCLUSION

Most studies in medical education did not describe incentives for participation. Information regarding incentives should be reported in all studies to help inform future recruitment efforts and also to understand the study context including factors that may influence participants motivation.

Continuous assessment of volunteers' satisfaction in clinical research through simplified questionnaires

OBJECTIVES

In our clinical research center, a 27 multiple-choice and 3 verbatim questions satisfaction questionnaire has been used since 2008 in order to assess the satisfaction of the volunteers participating in our studies. In this work, we aimed at reducing the number of questions of this cumbersome questionnaire while exploring the same dimensions.

MATERIALS AND METHODS

We used k-mean and hierarchical clustering to determine which questions provided the same information or, on the contrary, which questions were able to discriminate a satisfied volunteer from an unsatisfied volunteer.

RESULTS

We were able to reduce our satisfaction questionnaire from 30 questions to 6 closed-ended and 2 open-ended questions, which will allow to save volunteers time while increasing their participation rate.

CONCLUSION

This questionnaire could be used in other structures practicing clinical research, as part of their quality process.

Views of clinical trial participants on the readability and their understanding of informed consent documents

BACKGROUND

One of the ethical imperatives for a valid consent process in clinical medication trials is that the process be guided by and recorded in an informed consent document (ICD). Concerns have been expressed, however, about readability and participant understanding of ICDs, which are often 10-20 pages long. Objective measures of readability and understanding have been used to support these concerns in several articles, but surprisingly the voice of trial participants on ICDs has not been heard in previous studies. Hence, this study compares participants' subjective views on readability and their understanding of ICDs with those ICDs' objective readability scores. It also evaluates whether family, friends, and additional aids would foster better understanding of the ICD.

METHODS

Sixty current trial participants rated the readability and their understanding of deidentified standard ICDs. These had been sourced from two multicenter international Phase III trials on medication for diabetes mellitus and cancer.

RESULTS

Less than 10% of participants considered the ICDs difficult to read or difficult to understand in spite of objective readability scores at levels of about 12th grade education, but about a quarter considered the ICDs to be too technical. Participants gave mixed responses about friends or family members helping or the need for videos, pictures, additional reading material, and frequently answered questions (FAQ) sheets as an aid to their understanding.

CONCLUSIONS

These findings suggest individual clinical trial participants should be engaged on their views of an ICD, for doing so is part of informed consent as a process rather than consent being merely focused on written information. Such participant-specific engagement should guide whether family and friends, videos, pictures, additional reading material, and FAQ sheets would be of assistance in improving understanding.

The challenges of patient satisfaction: influencing factors and the patient - provider relationship in the United States

INTRODUCTION

Patient satisfaction is a phenomenon that has become influential in the inpatient setting with the introduction of the Hospital Consumer Assessment of Healthcare Practitioners and Systems (HCAHPS) survey in the United States. Patient satisfaction is a key goal of healthcare organizations and presents some challenges to providing quality patient care. Areas covered: This review will focus on the challenges patient satisfaction presents in the healthcare field, with a key focus on factors that influence patient satisfaction, the common problem of inappropriate antibiotic prescriptions and the importance of the patient-provider relationship. Expert commentary: While it is apparent that focused efforts to better understand patient satisfaction are necessary and that implementation of processes to enhance satisfaction are warranted, attention must be directed so that these interventions do not adversely influence the efficiency or quality of care. Continuous long-term relationships with healthcare providers encourage patient loyalty, effective healthcare and good lifestyle habits.

Informed consent for next-generation nucleotide sequencing studies: Aiding communication between participants and investigators

INTRODUCTION

Obtaining informed consent from prospective participants for research studies that include next-generation nucleotide sequencing (NGS) presents significant challenges because of the need to explain all the potential implications of participating, including the possible return of "incidental" findings, in easy-to-understand language.

METHODS AND RESULTS

After reviewing the consent processes at other institutions, we decided to supplement the protocol-specific informed consent form with the following: (1) a short pamphlet for the prospective participant that includes a series of questions that she or he is encouraged to ask the investigator, and (2) a more detailed companion guide for investigators to help them develop simple-language answers to the questions. Both documents are available to use or modify.

CONCLUSIONS

We propose an approach to obtaining informed consent for NGS studies that encourages discussion of key issues without creating a complex, comprehensive document for participants; it also maximizes investigator flexibility. We also suggest mechanisms to return restricted information to participants.

An ounce of prevention: A pre-randomization protocol to improve retention in substance use disorder clinical trials

BACKGROUND

Missing data in substance use disorder (SUD) research pose a significant threat to internal validity. Participants terminate involvement or become less likely to attend intervention and research visits for many reasons, which should be addressed prior to becoming problematic. During a 9-month study targeting stimulant abuse, early dropouts and participant reported attendance barriers led to implementing a structured, pre-randomization protocol with participants about retention and solution-focused strategies (the "Fireside Chat"). Our aim is to outline this approach and present data on intervention participation and research visit attendance after implementation.

METHODS/DESIGN

STimulant Reduction using Dosed Exercise (STRIDE) was a two-arm, multisite randomized clinical trial testing treatment-as-usual for stimulant abuse/dependence augmented by Exercise or Health Education. For both groups, study intervention visits at the site were scheduled 3/week for 12weeks followed by 1/week for 24weeks. During The Chat, research staff thoroughly reviewed participants' expectations, and barriers and solutions to retention. Fifteen participants were randomized (to Exercise or Health Education) prior to and fourteen were randomized after Chat implementation. Intervention and monthly follow-up attendance (before and after implementation) were compared at the site (N=29) that developed and rigorously implemented The Chat.

RESULTS

Individuals who participated in The Chat (n=14) attended significantly more intervention visits during weeks 1-12 (p<0.001) and weeks 13-36 (p<0.05) and attended more research visits (p<0.001).

DISCUSSION

Proactive discussion of expectations and barriers prior to randomization was associated with greater study attendance. SUD researchers should consider tailoring this approach to suit their needs. Further investigation is warranted.

Maternal participant experience in a South African birth cohort study enrolling healthy pregnant women and their infants

BACKGROUND

Critical to conducting high quality research is the ability to attract and retain participants, especially for longitudinal studies. Understanding participant experiences and motivators or barriers to participating in clinical research is crucial. There are limited data on healthy participant experiences in longitudinal research, particularly in low- and middle-income countries. This study aims to investigate quantitatively participant experiences in a South African birth cohort study.

METHODS

Maternal participant experience was evaluated by a self-administered survey in the Drakenstein Child Health Study, a longitudinal birth cohort study investigating the early life determinants of child health. Pregnant mothers, enrolled during the second trimester, were followed through childbirth and the early childhood years. Satisfaction scores were derived from the participant experience survey and quantitatively analyzed; associations between satisfaction scores and sociodemographic variables were then investigated using a linear regression model.

RESULTS

Data were included from 585 pregnant mothers (median age 26.6 years), who had participated in the study for a median time of 16 months. Overall participant satisfaction was high (median score 51/60) and associated with increased attendance of study visits. Reasons for participating were a belief that involvement would improve their health, their child's health or the health of family and friends. Potential reasons for leaving the study were inconvenience, not receiving clinical or study results, and unexpected changes in study visits or procedures. Variables associated with higher overall satisfaction scores were no prior participation in research, higher socioeconomic status, less intensive follow-up schedules and having experienced stressful life events in the past year.

CONCLUSIONS

Satisfaction scores were high and associated with increased visit attendance. Participants' perceived benefits of study participation, most notably the potential for an improvement in the health of their child, were a significant motivator to enroll and remain in the study. The consistent theme of perceived health benefits as a motivator to join and remain in the study raises the question of whether participation in research results in actual improvements in health.

Patient involvement in clinical research: why, when, and how

The development of a patient-centered approach to medicine is gradually allowing more patients to be involved in their own medical decisions. However, this change is not happening at the same rate in clinical research, where research generally continues to be carried out on patients, but not with patients. This work describes the why, when, and how of more active patient participation in the research process. Specific measures are proposed to improve patient involvement in 1) setting priorities, 2) study leadership and design, 3) improved access to clinical trials, 4) preparation and oversight of the information provided to participants, 5) post-study evaluation of the patient experience, and 6) the dissemination and application of results. In order to achieve these aims, the relative emphases on the ethical principles underlying research need to be changed. The current model based on the principle of beneficence must be left behind, and one that upholds the ethical principles of autonomy and non maleficence should be embraced. There is a need to improve the level of information that patients and society as a whole have on research objectives and processes; the goal is to promote the gradual emergence of the expert patient.

Perceptions and Attitudes towards Medical Research in the United Arab Emirates: Results from the Abu Dhabi Cohort Study (ADCS) Focus Group Discussions

Background

In developing medical research, particularly in regions where medical research is largely unfamiliar, it is important to understand public perceptions and attitudes towards medical research. In preparation for starting the first cohort study in the United Arab Emirates, the Abu Dhabi Cohort Study (ADCS), we sought to understand how we could improve the quality of the research process for participants and increase public trust and awareness of research.

Methods

We conducted six focus groups (FG), consisting of Emirati men and women aged above 18 years to resemble the target population for the ADCS. Sampling was purposive and convenient. Data collection was an iterative process until saturation was reached with no new themes identified. Text from each FG was analyzed separately by identifying emerging issues and organizing related concepts into categories or themes. A coding tree was developed, consisting of the main concepts, themes, subthemes and corresponding quotes. Both themes and main ideas were identified using inductive analysis.

Results

Forty-two participants enrolled at 3 academic centers (New York University Abu Dhabi, UAE University, Zayed University) and the Abu Dhabi blood bank. Focus group participants described lack of awareness of research as a challenge to participation in clinical research studies. Altruism, personal relevance of the research, and the use of role models were commonly identified motivators. Participants were generally satisfied with the informed consent process for the ADCS, but would be disappointed if not provided test results or study outcomes. Fear of a breach in confidentiality was a frequently expressed concern.

Conclusions

Participants join research studies for varied, complex reasons, notably altruism and personal relevance. Based on these insights, we propose specific actions to enhance participant recruitment, retention and satisfaction in the ADCS. We identified opportunities to improve the research experience through improved study materials and communication to participants and the broader community.

[Informed consent process in clinical trials: Insights of researchers, patients and general practitioners]

OBJECTIVE

Adequate information for patients and respect for their autonomy are mandatory in research. This article examined insights of researchers, patients and general practitioners (GPs) on the informed consent process in clinical trials, and the role of the GP.

DESIGN

A cross-sectional study using three questionnaires, informed consent reviews, medical records, and hospital discharge reports.

SETTING

GPs, researchers and patients involved in clinical trials.

PARTICIPANTS

Included, 504 GPs, 108 researchers, and 71 patients.

RESULTS

Consulting the GP was recommended in 50% of the informed consents. Participation in clinical trials was shown in 33% of the medical records and 3% of the hospital discharge reports. GPs scored 3.54 points (on a 1-10 scale) on the assessment of the information received by the principal investigator. The readability of the informed consent sheet was rated 8.03 points by researchers, and the understanding was rated 7.68 points by patients. Patient satisfaction was positively associated with more time for reflection.

CONCLUSIONS

GPs were not satisfied with the information received on the participation of patients under their in clinical trials. Researchers were satisfied with the information they offered to patients, and were aware of the need to improve the information GPs received. Patients collaborated greatly towards biomedical research, expressed satisfaction with the overall process, and minimised the difficulties associated with participation.

Participants' perception of pharmaceutical clinical research: a cross-sectional controlled study

BACKGROUND

There is scarce scientific information assessing participants' perception of pharmaceutical research in developed and developing countries concerning the risks, safety, and purpose of clinical trials.

METHODS

To assess the perception that 604 trial participants (cases) and 604 nonparticipants (controls) of pharmaceutical clinical trials have about pharmaceutical clinical research, we surveyed participants with one of four chronic diseases from 12 research sites throughout Mexico.

RESULTS

Participation in clinical trials positively influences the perception of pharmaceutical clinical research. More cases (65.4%) than controls (50.7%) perceived that the main purpose of pharmaceutical research is to cure more diseases and to do so more effectively. In addition, more cases considered that there are significant benefits when participating in a research study, such as excellent medical care and extra free services, with this being the most important motivation to participate for both groups (cases 52%, controls 54.5%). We also found a sense of trust in their physicians to deal with adverse events, and the perception that clinical research is a benefit to their health, rather than a risk. More controls believed that clinical trial participants' health is put at risk (57% vs 33.3%). More cases (99.2%) than controls (77.5%) would recommend participating in a clinical trial, and 90% of cases would enroll in a clinical trial again.

CONCLUSION

Participation in clinical trials positively influences the perception that participants have about pharmaceutical clinical research when compared to nonparticipants. This information needs to be conveyed to clinicians, public health authorities, and general population to overcome misconceptions.

Soliciting views of various communities on health research: a prelude to engagement in specific research projects

BACKGROUND

Members of the public are increasingly engaged in health-service and biomedical research and provide input into the content of research, design and data sharing. As there is variation among different communities on how research is perceived, to engage all sectors of the general public research institutions need to customize their approach.

OBJECTIVE

This paper explores how research institutions and community leaders can partner to determine the best ways to engage different sectors of the public in research.

DESIGN

Following a literature review, a research institution engaged with four different sectors of the public through their respective representative community-based organizations (CBOs) by interviews with leaders, community member focus groups and a joint project.

SETTING

San Diego and Imperial Counties, California, United States of America (USA).

CONCLUSION

Before embarking on more specific research projects, investigators can gain valuable insights about different communities' attitudes to, and understanding of, health services and biomedical research by interacting directly with members of the community, collaborating with community leaders, and jointly identifying steps of engagement tailored to the community.

Why do - or don't - patients with urinary tract infection participate in a clinical trial? A qualitative study in German family medicine

BACKGROUND

Insufficient patient recruitment can impair the conduct of clinical trials substantially, not least because a significant number of eligible patients decline trial participation. Though barriers and motivational factors have been worked out for patients with cancer or chronic diseases, little is known about primary care patients' perceptions towards trial participation when visiting their family practitioner (FP) with acute uncomplicated conditions. This study aims to assess primary care patients' motivation and barriers to participate in trials, and to identify factors that optimize patient recruitment in future trials.

METHODS

This study was embedded in a drug trial comparing two treatment strategies for women with uncomplicated urinary tract infection in primary care. Semi-structured telephone interviews both with trial participants and decliners were conducted. The interview guideline focused on patients' personal motivational or hampering factors. Further topics were study theme, FPs' role, randomization, trial procedures, and potential motivational factors or barriers presumed to be relevant for other patients. Transcripts were analyzed by summarizing content analysis.

RESULTS

20 interviews with trial participants and 5 interviews with trial decliners were conducted. RESULTS show various reasons for trial participation from three categories: personal aspects, trial related aspects and patient-physician-relationship. A relevant trial topic and perceived personal benefit promotes participation as well as the wish to support research in general. Additionally, a maximum of safety concerning symptom relief reassures patients significantly. Trust in the FP plays also an important role in the decision process. Trial decliners show strong individual treatment preferences, which, together with individual reasons, lead to trial refusals.

CONCLUSIONS

To optimize recruitment conditions for further clinical trials on acute and common conditions in family medicine, the following key issues should be considered: emphasizing patients' personal benefit, featuring patient relevant trial topics, providing a maximum of safety, keeping effort by trial procedures comfortable.

Risks and benefits of trial participation: A qualitative study of participants’ perspectives in Russia

Background:

The Russian Federation is one of the emerging clinical trial regions where the numbers of international clinical trials have been significantly rising over the course of recent years.

Purpose:

Our aims were to describe and explain risk–benefit calculus by clinical trial participants in Russia and to analyse the significance of the results for the ethical regulation of globalizing clinical trials.

Methods:

In-depth semi-structured interviews were conducted with 21 individuals participating in trials for cardiovascular disease. Analysis was based on the inductive constant comparative method.

Results:

Interviewed participants perceived multiple benefits in trial enrolment including regular check-ups, provision and explanation of individual test results, the opportunity to ask investigators for advice and the provision of treatment recommendations for those with limited access to a physician outside of the trial. Participants tried to manage risks of trial enrolment by paying attention to how they felt and reporting changes to investigators. Regular monitoring, the opportunity to drop out of the trial and health insurance provision in case of adverse events were viewed as further minimizing individual risks. Importantly, interviewed trial participants did not assess the risks and benefits of a single trial independently of wider social situation or particularities of their own health condition. Value of trial enrolment benefits for participants was enhanced by the healthcare system that was viewed as being unresponsive to the needs of people with cardiovascular disease. Therefore, in their risk–benefit assessment, participants weighed enrolment risks against the risks of dealing with their fragile health without continuous contact with a medical professional.

Limitations:

A relatively small number of interviews was conducted, only participants of cardiovascular disease trials were interviewed and the extent to which the described perspectives are generalizable is not established.

Conclusion:

The risk–benefit assessment as performed by most interviewed trial participants involved multiple components, including the ones unrelated to the trial itself, and was largely context-dependent. Perspectives of research participants can enrich frameworks for the evaluation of trial risks and benefits.

Peruvian Female Sex Workers' Ethical Perspectives on Their Participation in an HPV Vaccine Clinical Trial

This study examined female sex workers' evaluation of ethically relevant experiences of participating in an HPV4 vaccine clinical trial conducted in Lima, Peru (the Sunflower Study). The Sunflower Study provided all participants with HPV testing, treatment for those testing positive, and access to the vaccine for all testing negative. Themes that emerged from content analysis of interviews with 16 former participants included the importance of respectful treatment and access to healthcare not otherwise available and concerns about privacy protections, the potential for HIV stigma, and poststudy abandonment.
