A randomized study of multimedia informational aids for research on medical practices: Implications for informed consent

Comparing Attitudes Toward Different Consent Mediums: Semistructured Qualitative Study

BACKGROUND

As consent for data sharing evolves with the digital age, plain-text consent is not the only format in which information can be presented. However, designing a good consent form is highly challenging. The addition of graphics, video, and other mediums to use can vary widely in effectiveness; and improper use can be detrimental to users.

OBJECTIVE

This study aims to explore the expectations and experiences of adults toward consent given in infographic, video, text, newsletter, and comic forms in a health data sharing scenario to better understand the appropriateness of different mediums and identify elements of each medium that most affect engagement with the content.

METHODS

We designed mock consent forms in infographic, video, text, newsletter, and comic versions. Semistructured interviews were conducted with adults who were interviewed about their expectations for consent and were then shown each consent medium and asked about engaging elements across mediums, preferences for consent mediums, and the value of document quality criteria. We transcribed and qualitatively co-coded to identify themes and perform analyses.

RESULTS

We interviewed 24 users and identified different thematic archetypes based on participant goals, such as the Trust Seeker, who considered their own understanding and trust in organizations when making decisions. The infographic was ranked first for enhancing understanding, prioritizing information, and maintaining the proper audience fit for serious consent in health data sharing scenarios. In addition, specific elements such as structure, step-by-step organization, and readability were preferred engaging elements.

CONCLUSIONS

We identified archetypes to better understand user needs and elements that can be targeted to enhance user engagement with consent forms; this can help inform the design of more effective consent in the future. Overall, preferences for mediums are highly contextual, and more research should be done.

Current usage of explainer animations in trials: a survey of the UKCRC registered clinical trial units in the UK

BACKGROUND

Explainer animations are a means to communicate aspects of clinical trials to participants in a more engaging and accessible way. Delivered well these have the potential to enhance recruitment and retention. The range of media technology used to deliver this material is expanding rapidly but is highly fragmented. Usage of explainer animations across the UK is unknown, the aim of this research was to determine current usage across the 52 registered UK Clinical Research Collaboration (UKCRC) Clinical Trials Units (CTUs) to understand the current landscape and any barriers that could be preventing wider uptake of this functionality.

METHODS

A survey link was emailed to all UKCRC CTU Directors and Trial Management Leads to ascertain current usage of explainer animations within their CTU. The survey ran between 01 February 2023 and 07 March 2023.

RESULTS

Responses were received from 35 CTUs-representing a response rate of 67%. 24 CTUs (69%) reported that they had created/used at least one explainer animation within their unit, although the usage, cost, length and production activities varied among the units.

CONCLUSIONS

The survey showed that a high proportion of the UKCRC CTUs have used explainer animations to provide information to participants about clinical studies. For those not using the technology yet, the most common reasons cited were a lack of expertise, lack of resources and costs to produce them. One of the desired outcomes of this project is the creation of a free-to-use library of animations to encourage wider uptake and avoid duplication.

The Effects of Animations and Multimedia Messages on Public Engagement in Precision Medicine: Assessment of Moderation and Mediation

Public participation in precision medicine (PM) research is essential to achieving effective health care but has been impeded by a lack of awareness and basic knowledge. There is a critical need for educational materials that can clearly explain PM to foster involvement. This randomized controlled trial with a posttest-only control group design aims to assess the effects of educational messages delivered through animations relative to live-action videos and leaflets on intentions of involvement in PM research. Knowledge as the moderator and four mediators (engagement, vividness, trustworthiness, and cognitive value) of the intended effects were also evaluated. A total of 326 U.S. adults were sampled from Amazon Mechanical Turk. Among participants with less knowledge about PM, animations produced stronger information-seeking intentions and willingness to participate than leaflets. The effects of three message modalities were not significantly different among average and highly knowledgeable participants. Engagement and vividness mediated the effects of animations relative to two other message modalities. Trustworthiness and cognitive value mediated the effects of animations relative to live-action videos. Overall, animations can be an effective communication strategy to motivate involvement in PM but its effectiveness could decline as knowledge increases. The explanations and implications of the findings were discussed.

Assessing the role of interactivity: An evaluation of information aids to support the enrollment of precision medicine research programs

OBJECTIVE

Recruiting diverse participants for precision medicine (PM) research programs should overcome low literacy and varied expectations. Information aids (IA) can address these barriers through patient-centered education. The purpose of this study was to evaluate the effectiveness of three information aids (IA) on participating in PM.

METHODS

An experiment with 290 U.S. participants recruited from Mturk was conducted to compare the effects of three IAs on the outcomes related to participation. Three conditions included an interactive IA (i.e., providing PM-related information responding to each participant's questions), a static IA (i.e., providing uniform PM-related information), and a control condition (i.e., providing non-interactive information irrelevant to PM).

RESULTS

Both interactive and non-interactive IAs increased attitudes and information-seeking intentions, but not knowledge or participation intention. Perceived control and responsiveness mediated the effects of interactive IA.

CONCLUSION

Both interactive and static IAs supported enrollment efforts for PM through fostering attitudes and follow-up information-seeking. Increased perceived control and responsiveness are key to the effects of interactive IA.

PRACTICE IMPLICATIONS

IAs provide effective education and enrollment support for PM. Interactive IA can respond to individuals' inquiries and control the learning process.

Spanish Adaptation and Evaluation of Clinical Discussion Guides: Communicating the External Beam Radiotherapy Experience (CEBRE) en Español

PURPOSE

Cancer is the leading cause of death for the Hispanic/Latinx United States (US) community, which comprises 64% of the US population with limited English proficiency. Despite the common use of radiation therapy for cancer treatment, there is a dearth of radiation therapy educational materials-at appropriate reading levels-available in Spanish. To address the gap in patient-centered educational resources for communicating with Spanish-speaking patients about radiation therapy, we sought to linguistically and culturally adapt the Communicating the External Beam Radiotherapy Experience (CEBRE) clinical discussion guide series into Spanish.

METHODS AND MATERIALS

From January to December 2021, we developed and applied a stepwise methodology for Spanish adaptation of the discussion guides involving (1) professional translation; (2) interprofessional review for linguistic and cultural appropriateness and medical accuracy; (3) design review; and (4) evaluation for readability, understandability, and actionability using validated tools. We applied 4 indices for readability evaluation: Gilliam-Peña-Mountain, Läsbarhetsindex, Rate Index, and the Spanish Simple Measure of Gobbledygook. Two trained reviewers assessed understandability and actionability using the Patient Education Materials Assessment Tool.

RESULTS

After 2 revision rounds, 4 CEBRE en español discussion guides were produced through an interprofessional, iterative translation and linguistic/cultural adaptation process. Readability scores across the 4 guides ranged from 4.3 to 7.3 grade-level equivalents, thereby meeting the American Medical Association's 8th-grade standard. Patient Education Materials Assessment Tool analysis yielded near-perfect scores along understandability and actionability domains.

CONCLUSIONS

The stepwise linguistic/cultural adaptation process yielded a patient-centered guide that is appropriately readable, understandable, and actionable for Spanish-speaking patients receiving radiation therapy in the US. Future work should include an external evaluation of CEBRE en español by clinicians and patients. The methodology described can be applied to adapting resources for patient-centered communication in other fields of medicine and into other languages as part of an interprofessional approach to delivering equitable health care for all.

Sexual & reproductive health information on minor consent forms for pubertal suppression and gender affirming hormones

Introduction

Transgender and Nonbinary (TNB) youth need specialized sexual and reproductive health (SRH) information and counseling. One avenue for providing this information is the use of informed consent documents before initiating pubertal suppression (PS) and/or gender-affirming hormones (GAHs). This study aims to compare the type and amount of SRH information included on informed consent documents used across clinical sites providing PS and GAH to youth.

Methods

As part of a larger, IRB-approved survey on informed consent, providers of gender-related care to youth uploaded informed consent forms used in clinical practice. Publicly available forms were also included in analysis. Content analysis of these forms was undertaken using published clinical guidelines to inform coding and reflect the SRH implications of starting PS and GAH.

Results

21 unique consent documents were included in the content analysis (PS = 7, Masculinizing = 7, Feminizing = 7). SRH information on consent documents fell into 4 broad categories: (1) changes in sexual organs and functioning; (2) pregnancy and fertility information; (3) cancer risk; and (4) sexually transmitted infections. Forms varied considerably in the level of detail included about these SRH topics and most forms included implicit or explicit acknowledgement of the uncertainty that exists around certain SRH outcomes for TNB youth.

Conclusions

There was substantial variability in both SRH content and context across consent forms. The role of consent forms in fostering TNB youth's understanding of complex SHR information when initiating PS and GAHs needs further clarification and development. Future research should focus on ways to ensure provision of adequate SRH information for TNB youth.

Education and Consent for Population-Based DNA Screening: A Mixed-Methods Evaluation of the Early Check Newborn Screening Pilot Study

A challenge in implementing population-based DNA screening is providing sufficient information, that is, understandable and acceptable, and that supports informed decision making. Early Check is an expanded newborn screening study offered to mothers/guardians whose infants have standard newborn screening in North Carolina. We developed electronic education and consent to meet the objectives of feasibility, acceptability, trustworthiness, and supporting informed decisions. We used two methods to evaluate Early Check among mothers of participating infants who received normal results: an online survey and interviews conducted via telephone. Survey and interview domains included motivations for enrollment, acceptability of materials and processes, attitudes toward screening, knowledge recall, and trust. Quantitative analyses included descriptive statistics and assessment of factors associated with knowledge recall and trust. Qualitative data were coded, and an inductive approach was used to identify themes across interviews. Survey respondents (n = 1,823) rated the following as the most important reasons for enrolling their infants: finding out if the baby has the conditions screened (43.0%), and that no additional blood samples were required (20.1%). Interview respondents (n = 24) reported the value of early knowledge, early intervention, and ease of participation as motivators. Survey respondents rated the study information as having high utility for decision making (mean 4.7 to 4.8 out of 5) and 98.2% agreed that they had sufficient information. Knowledge recall was relatively high (71.8–92.5% correct), as was trust in Early Check information (96.2% strongly agree/agree). Attitudes about Early Check screening were positive (mean 0.1 to 0.6 on a scale of 0–4, with lower scores indicating more positive attitudes) and participants did not regret participation (e.g., 98.6% strongly agreed/agreed Early Check was the right decision). Interview respondents further reported positive attitudes about Early Check materials and processes. Early Check provides a model for education and consent in large-scale DNA screening. We found evidence of high acceptability, trustworthiness and knowledge recall, and positive attitudes among respondents. Population-targeted programs need to uphold practices that result in accessible information for those from diverse backgrounds. Additional research on those who do not select screening, although ethically and practically challenging, is important to inform population-based DNA screening practices.

A Study of a Culturally and Contextually Situated Multimedia Approach to Recruit a Hard-to-Reach Spanish-Speaking Population for a Randomized Control Trial (RCT)

Study designs involving randomization can be difficult to communicate to participants, especially those with low literacy. The literature on strategies to explain research concepts is limited, especially for non-English speakers. We measured the effectiveness of a culturally and contextually situated multimedia approach to recruit a cohort of 60 female Mexican immigrants (FMI) to a randomized control trial (RCT) to reduce social isolation and depression. This strategy was designed to explain the concept of randomization, explain what participating in the research study entailed, and ensure informed consent. Potential participants viewed a presentation explaining the study and a video including animation with voice-over explaining the concept of randomization. We administered a pre/post survey. Respondents (N = 59) reported an increase in their understanding of randomization, intention to enroll, and attitude towards participating in research. We conclude that a culturally and contextually situated multimedia approach is an effective model when recruiting underrepresented populations with low literacy for RCTs.

Struggling with extensive informed consent procedures for cancer trials-is there even a benefit for the patients?

Purpose

Informed consent procedures in clinical trials often differ in length and complexity to those in clinical routine care. Little is known about the benefit of extensive procedures as intended in clinical trials compared to procedures in routine cancer treatment.

Methods

In two different clinical studies performed at a comprehensive cancer center, we compared patients’ comprehension and satisfaction of current informed consent procedures in routine clinical care with the level of comprehension and satisfaction of patients treated within clinical trials. Patients with a new cancer diagnosis and recent informed consent received a questionnaire about satisfaction, comprehension, time management, and physician–patient relationship of the informed consent process. Patients in cohort 1 consented to cancer treatment within a clinical trial and were additionally interviewed in a structured way; patients in cohort 2 consented to “standard” chemotherapy and received a follow-up questionnaire after 6 months.

Results

In cohort 1, 82 patients completed the questionnaire and had an additional structured interview. They were treated in 41 different trials, receiving up to 40 pages of educational material. In cohort 2, 89 patients completed the first and 52 completed the follow-up questionnaire after receiving a standard informed consent form of 6 pages. Subjective understanding and satisfaction with the information provided was equally very high. However, deficits in objective understanding were observed in both cohorts.

Conclusion

Extensive informed consent procedures for clinical cancer trials have not been associated with a higher level of satisfaction or measurable objective understanding; therefore, the benefit seems to be limited.

An Ethics Checklist for Digital Health Research in Psychiatry: Viewpoint

Background

Psychiatry has long needed a better and more scalable way to capture the dynamics of behavior and its disturbances, quantitatively across multiple data channels, at high temporal resolution in real time. By combining 24/7 data—on location, movement, email and text communications, and social media—with brain scans, genetics, genomics, neuropsychological batteries, and clinical interviews, researchers will have an unprecedented amount of objective, individual-level data. Analyzing these data with ever-evolving artificial intelligence could one day include bringing interventions to patients where they are in the real world in a convenient, efficient, effective, and timely way. Yet, the road to this innovative future is fraught with ethical dilemmas as well as ethical, legal, and social implications (ELSI).

Objective

The goal of the Ethics Checklist is to promote careful design and execution of research. It is not meant to mandate particular research designs; indeed, at this early stage and without consensus guidance, there are a range of reasonable choices researchers may make. However, the checklist is meant to make those ethical choices explicit, and to require researchers to give reasons for their decisions related to ELSI issues. The Ethics Checklist is primarily focused on procedural safeguards, such as consulting with experts outside the research group and documenting standard operating procedures for clearly actionable data (eg, expressed suicidality) within written research protocols.

Methods

We explored the ELSI of digital health research in psychiatry, with a particular focus on what we label “deep phenotyping” psychiatric research, which combines the potential for virtually boundless data collection and increasingly sophisticated techniques to analyze those data. We convened an interdisciplinary expert stakeholder workshop in May 2020, and this checklist emerges out of that dialogue.

Results

Consistent with recent ELSI analyses, we find that existing ethical guidance and legal regulations are not sufficient for deep phenotyping research in psychiatry. At present, there are regulatory gaps, inconsistencies across research teams in ethics protocols, and a lack of consensus among institutional review boards on when and how deep phenotyping research should proceed. We thus developed a new instrument, an Ethics Checklist for Digital Health Research in Psychiatry (“the Ethics Checklist”). The Ethics Checklist is composed of 20 key questions, subdivided into 6 interrelated domains: (1) informed consent; (2) equity, diversity, and access; (3) privacy and partnerships; (4) regulation and law; (5) return of results; and (6) duty to warn and duty to report.

Conclusions

Deep phenotyping research offers a vision for vastly more effective care for people with, or at risk for, psychiatric disease. The potential perils en route to realizing this vision are significant; however, and researchers must be willing to address the questions in the Ethics Checklist before embarking on each leg of the journey.

Tailored Messages About Research Participation: Using an Interactive Information Aid to Improve Study Recruitment

After a diagnosis of cancer (or other serious disease), patients may be asked to consider joining a clinical trial. Because most people are unfamiliar with the scientific concepts that are necessary to the provision of meaningful informed consent, patient education is necessary. Increasing knowledge alone is not sufficient; understanding how clinical trial participation aligns with personal circumstances and knowledge is central to the decision-making process. In this study, 302 cancer patients and survivors evaluated an interactive information aid (IA) designed to inform their decision to join a research study or clinical trial by providing tailored information to patients' responses to questions pertaining to seven key barriers or facilitators of clinical trial participation. The development of the IA was done with input from the authors' Clinical Translational Science Institute; linked components of the IA were vetted by members and leaders of the institution's NCI-designated comprehensive cancer center. Results of the study indicated that the information aid was successful in significantly reducing fears and increasing knowledge, attitudes, perceived behavioral control, and behavioral intentions about research participation relative to a control condition. Thus, an interactive information aid that provides information that is responsive to patients' values, knowledge, and personal circumstances can help patients to be better prepared to consider a decision about research participation.

Comparing a Multimedia Digital Informed Consent Tool With Traditional Paper-Based Methods: Randomized Controlled Trial

Background

The traditional informed consent (IC) process rarely emphasizes research participants’ comprehension of medical information, leaving them vulnerable to unknown risks and consequences associated with procedures or studies.

Objective

This paper explores how we evaluated the feasibility of a digital health tool called Virtual Multimedia Interactive Informed Consent (VIC) for advancing the IC process and compared the results with traditional paper-based methods of IC.

Methods

Using digital health and web-based coaching, we developed the VIC tool that uses multimedia and other digital features to improve the current IC process. The tool was developed on the basis of the user-centered design process and Mayer’s cognitive theory of multimedia learning. This study is a randomized controlled trial that compares the feasibility of VIC with standard paper consent to understand the impact of interactive digital consent. Participants were recruited from the Winchester Chest Clinic at Yale New Haven Hospital in New Haven, Connecticut, and healthy individuals were recruited from the community using fliers. In this coordinator-assisted trial, participants were randomized to complete the IC process using VIC on the iPad or with traditional paper consent. The study was conducted at the Winchester Chest Clinic, and the outcomes were self-assessed through coordinator-administered questionnaires.

Results

A total of 50 participants were recruited in the study (VIC, n=25; paper, n=25). The participants in both groups had high comprehension. VIC participants reported higher satisfaction, higher perceived ease of use, higher ability to complete the consent independently, and shorter perceived time to complete the consent process.

Conclusions

The use of dynamic, interactive audiovisual elements in VIC may improve participants’ satisfaction and facilitate the IC process. We believe that using VIC in an ongoing, real-world study rather than a hypothetical study improved the reliability of our findings, which demonstrates VIC’s potential to improve research participants’ comprehension and the overall process of IC.

What Motivates You to Share? The Effect of Interactive Tailored Information Aids on Information Sharing about Clinical Trials

Cancer patients learn about research studies outside of the clinical environment, including websites, print and online advertisements, and interpersonal interactions. When cancer patients share credible information about clinical trials, they also frequently help clarify misunderstandings that may exist in their social networks. The present study investigated how an interactive tailored information aid on clinical trial participation motivated patients' information sharing behaviors. In this study of 312 cancer patients and survivors, an interactive tailored information aid improved patients' likelihood of sharing online and offline information more than a non-interactive tool. Information sharing was directly predicted by cognitive absorption and perceived visual informativeness. In addition, perceived utility and ease of use indirectly impact information sharing positively through the antecedent factors of user engagement and design esthetics. Education level further moderated this effect; information sharing was higher among patients with more education. The implications of these findings are discussed and recommendations for future research are provided.

The Ethics of Consent in a Shifting Genomic Ecosystem

The collection and use of human genetic data raise important ethical questions about how to balance individual autonomy and privacy with the potential for public good. The proliferation of local, national, and international efforts to collect genetic data and create linkages to support large-scale initiatives in precision medicine and the learning health system creates new demands for broad data sharing that involve managing competing interests and careful consideration of what constitutes appropriate ethical trade-offs. This review describes these emerging ethical issues with a focus on approaches to consent and issues related to justice in the shifting genomic research ecosystem.

Breast Implant-Associated Anaplastic Large Cell Lymphoma Online Education Tools: A Multimetric Analysis

PURPOSE

In light of highly publicized media coverage on breast implant recalls and Food and Drug Administration hearings on breast implant safety, online searches of these topics have surged. It is thus critical to determine whether such searches are providing meaningful information for those who use them. Patient/laywomen-directed online education materials on breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) must not only be comprehensible but also accurate, actionable, and culturally concordant, especially as more diverse populations turn to the internet for breast implant-related information. This study assessed the overall suitability of BIA-ALCL patient-directed educational text and video-based materials online.

METHODS

This was a cross-sectional, multimetric investigation of online text- and video-based patient-directed educational materials for BIA-ALCL using multiple validated measures. Two reviewers assessed each resource. Kruskal-Wallis and Fisher exact analyses were used as appropriate to compare text- and video-based online resources.

RESULTS

In total, 30 websites and 15 videos were evaluated, more than half (56%) of which were from academic/physician or governmental/nonprofit sources. Overall, website and video content, as well as quality, varied by source. Academic/physician or governmental/nonprofit sources tended to be more comprehensive and have higher-quality information than commercial/media outlet sources. Median actionability of websites was 38%, well below the threshold of 70% used in the literature to identify actionable resources. The median suitability score for BIA-ALCL websites was 57%, which is considered "adequate" based on published thresholds. The mean overall Cultural Sensitivity Assessment Tool score for websites was 2.4; Cultural Sensitivity Assessment Tool scores higher than 2.5 are generally regarded as culturally sensitive. In general, videos were more understandable than websites. Substantial interrater reliability across the validated tools used in this study was noted using Pearson correlation coefficients.

CONCLUSIONS

Online resources varied in content and quality by source. As BIA-ALCL becomes an increasingly salient topic among both providers and patients, it is important to empower women with accurate information about this implant-associated cancer. Of available resources, providers should refer patients or those seeking more information to websites from governmental/academic organizations (".gov" or ".org" domains) and videos from academic/physician or governmental sources, given that among high-quality resources, these were most clear/comprehensible. Overall, there is a need for improved online content on this topic.

Untangling interactivity's effects: The role of cognitive absorption, perceived visual informativeness, and cancer information overload

OBJECTIVE

Learning about clinical trials is as stressful and challenging for cancer patients as it is for the clinical staff who provide education to patients. Information aids (IAs) can support both discussions and patients' decision-making, especially when IAs offer interactive features that provide information based on individuals' needs and experiences. However, it is not clear which factors contribute to interactive IAs' effectiveness.

METHODS

An experiment with cancer patients and survivors (n = 313) compared the effects of two IAs about clinical trial participation: one with modality (i.e. website/technological) interactivity only and one with both modality and message interactivity (i.e. provides information contingent on individual users' information needs).

RESULTS

The IA with both modality and message interactivity features elicited the higher perceived visual informativeness (PVI) and cognitive absorption (CA) scores. The model supports the moderating role of PVI and cancer information overload (CIO), and the mediating role of CA.

CONCLUSION

The IA with both modality and message interactivity better supported individuals' decision-making and improved attitudes and knowledge scores. CIO was experienced more by participants using the modality interactivity-only IA.

PRACTICE IMPLICATIONS

Message interactivity may simplify individuals' cognitive processes. IAs about clinical trial participation should include both message and modality interactivity.

An Evaluation of Clinical Trial Multimedia to Support Hispanic Cancer Patients' Informational and Decision-Making Needs

The inclusion of diverse populations in clinical trial research is a social justice imperative. Creating the communicative tools that can support cancer patients across varied cultural backgrounds in processing complex clinical trial information, to achieve informed consent, has been a challenge. This study sought to evaluate specific clinical trial multimedia-a website, four animations, and a decision aid-to meet the decision-making and informational needs of Hispanic patients. The multimedia content was positively evaluated by Hispanic cancer patients. However, the discussions also yielded important steps for culturally adapting these tools to account for particular informational needs and cultural values that would be important to incorporate into these, and future, clinical trial multimedia interventions that target Hispanic populations.

Participants' Comprehension of the Informed Consent in an Epidemiological Study on Dementia Prevalence: A Qualitative Study

Aim: In the absence of an effective treatment, informed participation in dementia research can hardly be underestimated. However, although informed consent is key in biomedical research, it may become a barrier to participation. Whether informed consent may cause confusion and contribute to unfair participant selection in dementia research is not known. In preparation of a future epidemiological study on the prevalence and impact of dementia in Switzerland, we aimed to conduct a qualitative study to explore participants' comprehension of the purpose of informed consent form and process shortly after participation in the pilot and validation study that preceded the large scale survey. Methods: We conducted a qualitative study with 22 participants of the validation phase of an epidemiological study on the prevalence and impact of dementia in Switzerland to capture their understanding of both the nature and the content of the informed consent form and process. Participants were older adults (65 years or more) eligible for a dementia epidemiological study and their informant (a person who could provide information on their health and cognition). None of the participants reported to be suffering from dementia at the time of the interview. Results: We found that participants held inaccurate and potentially trust-threatening beliefs regarding the scope of the informed consent. Participants identified contradictory contextual, formal and content needs that are difficult to be fulfilled, and misperceived the clinical and research settings in terms of informed consent procedures. Conclusions: Participants and their proxies should be informed about both the scope of the informed consent process, and the content of the informed consent document in a focused, age-appropriate manner, while dispelling confusion about the purpose of research.

Interdisciplinary development of a standardized introduction to gene drives for lay audiences

BACKGROUND

While there is wide consensus that the public should be consulted about emerging technology early in development, it is difficult to elicit public opinion about innovations unfamiliar to lay audiences. We sought public input on a program of research on genetic engineering to control mosquito vectors of disease that is led by scientists at the University of California and funded by the U.S. Defense Advanced Research Projects Agency (DARPA). In preparation for this effort, we developed a series of narrated slideshows to prompt responses to the development of gene drive mosquito control strategies among lay people. We describe the development and content of these slideshows and evaluate their ability to elicit discussions among focus group participants.

METHODS

In developing these materials, we used an iterative process involving input from experts in molecular genetics and vector control. Topics were chosen for their relevance to the goals of the scientists leading the program of research. Significant time was devoted to crafting explanations that would be accessible to uninitiated members of the public but still represent the science accurately. Through qualitative analysis of focus group discussions prompted by the slideshows, we evaluated the success of these slideshows in imparting clear technical information sufficient to inform lay discussion.

RESULTS

The collaboration resulted in a series of four narrated slideshows that were used to anchor discussions in online focus groups. Many participants described the slideshows as interesting and informative, while also raising concerns and possible risks that were not directly addressed in the material presented. Open-ended comments from participants suggest that the slideshows inspired critical questions, reflection, and conversation about genetically engineered and gene drive mosquitoes. After the final and most technically complex slideshow, however, some respondents made comments suggestive of overwhelm or confusion.

CONCLUSION

Our narrated slideshows prompted engaged conversations about genetically engineered mosquitoes among members of the public who were generally naïve to this technology. Narrated slideshows may serve as viable and useful tools for future public engagement on other controversial emerging medical and public health technologies.

Implementation of Electronic Informed Consent in Biomedical Research and Stakeholders' Perspectives: Systematic Review

Background

Informed consent is one of the key elements in biomedical research. The introduction of electronic informed consent can be a way to overcome many challenges related to paper-based informed consent; however, its novel opportunities remain largely unfulfilled due to several barriers.

Objective

We aimed to provide an overview of the ethical, legal, regulatory, and user interface perspectives of multiple stakeholder groups in order to assist responsible implementation of electronic informed consent in biomedical research.

Methods

We conducted a systematic literature search using Web of Science (Core collection), PubMed, EMBASE, ACM Digital Library, and PsycARTICLES. PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines were used for reporting this work. We included empirical full-text studies focusing on the concept of electronic informed consent in biomedical research covering the ethical, legal, regulatory, and user interface domains. Studies written in English and published from January 2010 onward were selected. We explored perspectives of different stakeholder groups, in particular researchers, research participants, health authorities, and ethics committees. We critically appraised literature included in the systematic review using the Newcastle-Ottawa scale for cohort and cross-sectional studies, Critical Appraisal Skills Programme for qualitative studies, Mixed Methods Appraisal Tool for mixed methods studies, and Jadad tool for randomized controlled trials.

Results

A total of 40 studies met our inclusion criteria. Overall, the studies were heterogeneous in the type of study design, population, intervention, research context, and the tools used. Most of the studies’ populations were research participants (ie, patients and healthy volunteers). The majority of studies addressed barriers to achieving adequate understanding when using electronic informed consent. Concerns shared by multiple stakeholder groups were related to the security and legal validity of an electronic informed consent platform and usability for specific groups of research participants.

Conclusions

Electronic informed consent has the potential to improve the informed consent process in biomedical research compared to the current paper-based consent. The ethical, legal, regulatory, and user interface perspectives outlined in this review might serve to enhance the future implementation of electronic informed consent.

Impact of implementing an online interactive educational tool for future HIV "cure" research in an HIV clinic waiting room in Cape Town, South Africa

Access to antiretroviral treatment (ART) in South Africa is suboptimal and erratic. For those on treatment, compliance remains a significant challenge. Interruptions to ART have negative implications for the individual and the epidemic. ART is therefore not a sustainable solution and there is an urgent need for a cure. As HIV cure research expands globally, the need to engage community members about cure is becoming a priority. It is vital that potential trial participants understand basic HIV cure research concepts. An online interactive educational tool was co-created with HIV stakeholders to engage and inform HIV research trial participants. The study was conducted with patients at the FAMCRU HIV clinic at Tygerberg Hospital in Cape Town, South Africa. The educational tool comprises two modules that provide information on HIV prevention, treatment and cure research. Participants completed a questionnaire before and after interacting with the programme. There was a significant increase in knowledge scores of participants demonstrated after using the tool. The interactive tool was successful in increasing participants' knowledge of HIV prevention, treatment and cure research.

A randomized controlled trial comparing video-assisted informed consent with standard consent for Mohs micrographic surgery

Background

There is a need for improvement in informed medical consent to address the lack of standardization and to increase patient engagement.

Objective

To investigate the use of a video to aid informed consent for Mohs micrographic surgery and evaluate patient understanding, satisfaction, anxiety, and time savings relative to verbal consent.

Methods

A 2-armed randomized controlled trial involving 102 patients compared video-assisted consent with a control group who underwent consent in the standard verbal manner. All participants underwent questionnaire-based testing of knowledge, satisfaction, and anxiety, and the time of each consultation was measured.

Results

Patients who watched the video performed significantly better in the knowledge questionnaire compared with the control group (P = .02), were more satisfied with their understanding of the risks of Mohs micrographic surgery (P = .013), and spent less time with their physician (P = .008). Additionally, 78.4% of video group patients reported that they preferred seeing the video before speaking with their physician.

Limitations

The study design may not replicate day-to-day clinical practice.

Conclusion

Video-assisted consent for Mohs micrographic surgery improves patient knowledge, leads to a better understanding of the risks, and saves physicians time without compromising patient satisfaction and anxiety levels in this study setting.

Genetic Counseling and the Central Tenets of Practice

Genetic counseling is a profession growing and evolving at an extraordinary rate. This growth is driven by an explosion in what we know, as a result of progress in science, technology, and bioinformatics, and an explosion in what we do not know, as we strive to understand the impact of genomic information on the lives of our patients and clients. Genetic counselors work in an increasing number of subspecialties and diversity of settings. But although the field has evolved, it has maintained a remarkably unchanged core of shared values and beliefs. The heart of genetic counseling practice is the therapeutic relationship, with its dual role of providing information and facilitating assimilation of that information to personalize health-related decision-making and foster successful adaptation. Genetic counseling aims to communicate cutting-edge genomic science within an empathic understanding of the client/patient's concerns and needs. In pursuit of these goals, further assessment of genetic counseling's effectiveness is needed to facilitate evidence-based practices and to scale counseling resources.

Supporting informed clinical trial decisions: Results from a randomized controlled trial evaluating a digital decision support tool for those with intellectual disability

Background

Informed consent requires that individuals understand the nature of the study, risks and benefits of participation. Individuals with intellectual disabilities (ID) have cognitive and adaptive impairments that may affect their ability to provide informed consent. New treatments and clinical trials for fragile X syndrome, the most commonly known inherited cause of ID, necessitate the development of methods to improve the informed consent process. The goal of this study was to compare the efficacy of a digital decision support tool with that of standard practice for informed consent and to examine whether the tool can improve decisional capacity for higher functioning individuals.

Methods

Participants (N = 89; mean age = 21.2 years) were allocated to the experimental group (consenting information provided via the digital decision support tool), or the comparison group (information provided via standard practice). Participants were assessed on four aspects of decisional capacity (Understanding, Appreciating, Reasoning, and Expressing a choice). We used regression analyses to test the impact of the tool on each outcome, repeating the analyses on the higher functioning subsample.

Results

No differences existed in any domain of decisional capacity for the sample in full. However, participants in the higher IQ subsample who used the tool scored better on Understanding after adjustment (β = 0.25, p = 0.04), but not on Appreciating or Reasoning. No differences by experimental group existed in the decision to join the hypothetical trial for the full sample or higher functioning subsample.

Conclusions

A decision support tool shows promise for individuals with fragile X syndrome with higher cognitive abilities. Future studies should examine the level of cognitive ability needed for sufficient understanding, whether these findings can be translated to other clinical populations, and the impact of the tool in larger trials and on trial retention.

Animations about Clinical Trial Participation for Cancer Patients and Survivors

Communicating about clinical trials and medical research is challenging. An appropriate communication is essential to reduce some of the barriers associated with poor patients' enrollment in clinical trials and with patients' uninformed consent or uninformed refusal. An experiment was conducted to assess the effects of educational animations compared to brochures with and without visuals, and with the materials currently used by the NIH. These materials focused on explaining placebos, randomization, the steps necessary to enroll in a clinical trial, and how and by who patients' protection is ensured. A total of 1194 cancer patients and survivors completed this 4 by 4 experiment through a Qualtrics panel. The findings showed that animations improved participants knowledge about and attitudes toward clinical trials and were more effective than brochures presenting information from the NIH, especially for those individuals with low motivation and low ability to comprehend health-related information. Several evidence-based theoretical explanations of the functioning of animations are provided.

Facilitating Informed Permission/Assent/Consent in Pediatric Clinical Trials

Individuals approached to participate in human subjects research, irrespective of age, must be completely apprised of the study, and researchers must ensure that the information is understood to the fullest extent possible, prior to decision making. However, evolving regulatory and institutional requirements have led to permission/assent/consent (PAC) forms that are unnecessarily complex, serving only to exacerbate the challenges associated with communicating this important information to prospective participants. At greatest risk are children and other individuals with low literacy, limited English proficiency, and diminished mental capacity, populations all too often neglected in clinical research. This paper examines various strategies that have been evaluated to facilitate informed PAC, drawing on experiences across a broad array of populations whose needs overlap with those of children. These strategies range from simplifying PAC forms for readability and creating multimedia PAC delivery tools to actively engaging participants on their understanding of PAC elements by leveraging testing, rewards, and third-party communications. Notably, the findings from strategies that have been explored in more than one setting are uniformly mixed with respect to their ability to improve comprehension, underscoring the challenges that persist in designing, implementing, and objectively examining strategies intended to facilitate informed PAC. However, these studies do serve to highlight efforts that may reduce anxiety around, and increase the satisfaction of participants with, the PAC process. Ultimately, accommodating a diverse participant pool will require the consideration, and continual refinement, of various PAC strategies along with the engagement of team members who are intimately familiar with these populations.

Improving quality of the informed consent process: Developing an easy-to-read, multimodal, patient-centered format in a real-world setting

OBJECTIVE

To develop a patient-centered informed consent and assessment tool written at a 6th grade-level that is multimodal, affordable, transportable, and readily modifiable for protocol updates.

METHODS

This quality improvement initiative was performed in two phases on an actively-recruiting study at a pediatric diabetes clinic. In phase I, 38 volunteers underwent the standard-paper consent process, a comprehension assessment and provided feedback. Using feedback and the structure of the Plan-Do-Study-Act cycle a multimodal consent and assessment were developed. In phase II, volunteers were randomized to the standard (n = 25) or the multimodal consent (n = 25) and all completed the same comprehension assessment via touch-screen tablet. Primary outcomes were comparison of the individual and total comprehension assessment scores.

RESULTS

Total comprehension scores were higher in the multimodal versus the standard consent group (p <  0.001) and on the elements of benefits (p <  0.001), risks (p <  0.001), volunteerism (p <  0.012), results (p <  0.001), confidentiality (p <  0.004) and privacy (p < 0.001).

CONCLUSION

A multimodal consent and assessment presented sequentially on a touch-screen tablet were patient-centered enhancements to standard consent.

PRACTICE IMPLICATIONS

Multimodal standardization of delivery with improved readability may strengthen the informed consent process.

The Challenges of Informed Consent in High-Stakes, Randomized Oncology Trials: A Systematic Review

Importance. Oncology trials often entail high-stakes interventions where potential for morbidity and fatal side effects, and for life-prolongation or cure, intensify bioethical issues surrounding informed consent. These challenges are compounded in multistage randomized trials, which are prevalent in oncology. Objective. We sought to elucidate the major barriers to informed consent in high-stakes oncology trials in general and the best consent practices for multistage randomized trials. Evidence Review. We queried PubMed for original studies published from January 1, 1990, to April 5, 2018, that focused on readability, quality, complexity or length of consent documents, motivation and sickness level of participants, or interventions and enhancements that influence informed consent for high-stakes oncologic interventions. Exclusion criteria included articles focused on populations outside industrialized countries, minors or other vulnerable populations, physician preferences, cancer screening and prevention, or recruitment strategies. Additional articles were identified through comprehensive bibliographic review. Findings. Twenty-seven articles were retained; 19 enrolled participants and 8 examined samples of consent documents. Methodologic quality was variable. This body of literature identified certain challenges that can be readily remedied. For example, the average length of the consent forms has increased 10-fold from 1987 to 2010, and patient understanding was shown to be inversely proportional to page count; shortening forms, or providing a concise summary as mandated by the revised Common Rule, might help. However, barriers to understanding that stem from deeply ingrained and flawed sociocultural perceptions of medical research seem more difficult to surmount. Although no studies specifically addressed problems posed by multiple sequential randomizations (such as change in risk-benefit ratio due to time-varying treatment responses or organ toxicities), the findings are likely applicable and especially relevant in that context. Concrete suggestions for improvement are proposed.

Integrating Parents in Neonatal and Pediatric Research

BACKGROUND

Parents and their infants are the beneficiaries of neonatal and pediatric research, but in the past they have been excluded from most stages of research projects. As a result, many projects may fail to produce the most worthwhile information for parents and families. Lately, veteran resource parents and patients have been increasingly integrated in research initiatives.

METHODS

Benchmarking of neonatal and pediatric research initiatives where resource parents and/or ex neonatal patients have helped to optimize pediatric research. We review ways in which resource parents/patients can be involved in research, with examples and practical ideas of how to proceed.

RESULTS

Resource parents/patients can be collaborators in research and be integrated in many steps: prioritizing research projects, designing trials, determining the outcomes of interest, ethics review, developing and improving consent procedures, collection and interpretation of data, participation in data safety monitoring committees, publication of results, and presentation to peer groups. Some of the strategies for integration of stakeholders in clinical research are more complex, may involve risk and require more training than others.

CONCLUSION

We suggest that groups wanting to involve parents in their research endeavors start with simpler tasks that entail less risk and develop teams of resource parents who have differing interests and abilities. Quality control of programs is essential, such as frequently giving and obtaining feedback from resource parents/patients and researchers. In the future, integration of resource parents/patients into every step of clinical research will be essential to ensure that parent and family important outcomes are examined.

Ready to Make A Decision: A Model of Informational Aids to Improve Informed Participation in Clinical Trial Research

Enrollment rates for cancer clinical trials remain low, affecting the generalizability of new treatments. Research shows that many patients face significant challenges in understanding basic clinical trial vocabulary and making informed decisions about participation. Informational aids (IA) are developed to address these challenges and support decision making of cancer clinical trial participation. The present study proposed and tested a structural path model to explain the efficacy of three (i.e., interactive, non-interactive, non-cancer control) IAs. The results revealed that clinical trial participation intention was associated with attitudes and social constructs (i.e., social norm, social sharing, and cues to action). Ease of use, rather than knowledge, was the primary communication feature of IA that influenced the outcome variables. The path relations linking messages features, mediators, and outcome variables were different across all three IAs. The results therefore provide theoretical and practical implications for the use and development of IAs to support clinical trial accrual.

Engaging populations underrepresented in research through novel approaches to consent

The lack of diversity of populations included in genomics databases is an important inhibitor of genomic discovery from bench to bedside. One way to increase the diversity of participants is to ensure that informed consent processes are designed for cultural and linguistic concordance for non-majority populations. This article describes two case studies of genomics research studies that are using novel approaches to informed consent to increase recruitment and retention of participants from traditionally underrepresented populations: The Cancer Health Assessments Reaching Many (CHARM) study, part of the Clinical Sequencing Evidence-Generating Research (CSER) consortium, and the All of Us Research Program, part of the Precision Medicine Initiative. We conclude by proposing a community of practice among researchers seeking to improve informed consent to increase diversity in genomics research.

Medical and physician assistant students' views on integrating comics into medical education

This article was migrated. The article was marked as recommended. Purpose: This study explored comics as a tool for teaching medical and physician assistant (PA) students about end-of-life decisions and advance care planning. Methods: Using a mixed method convergent design, a survey (consisting of a five-point Likert scale and open-ended questions) was administered to second-year medical and first-year PA students enrolled in an Ethics and Professionalism class at a US medical school. The survey assessed students' perspectives on the addition of a comic "Betty P." to assigned readings and about the use of comics in the classroom. Quantitative results were compared by demographics, and open-ended responses were analyzed qualitatively for emergent themes. Quantitative and qualitative findings were compared for correspondence. Results: Of the 145 students who completed the survey (83%), 141 students (81%) had read the comic. The vast majority (89%) felt that "Betty P." helped them understand end of life care for patients, and 84% felt that the comic did not distract them from the seriousness of the subject. Qualitative analysis revealed 2 major themes: 1) comics were educational, and 2) comics engaged learners emotionally. We observed convergence between quantitative and qualitative results. Conclusion: Integrating comics as a supplemental teaching tool is an innovative way to engage medical students.
