Development and evaluation of a web-based assent for adolescents considering an HIV vaccine trial

Assessment of Consent Comprehension Among Kenyan Adolescents, Young Adults, and Parents: Comparison of Enhanced and Standard Consenting Procedures

PURPOSE

Youth aged 15-19 years and parents of minors aged 15-17 years in sub-Saharan Africa are under-represented in empirical consent research. Thus, knowledge is limited concerning the adequacy of consent procedures and need for strategies to improve consent comprehension among these groups. We assessed comprehension following standard consent procedures and evaluated an enhanced procedure among Kenyan youth and parents.

METHODS

Participants were adolescents aged 15-17 years (n = 273), their parents (n = 196), and young adults aged 18-19 years (n = 196). We used a quasi-experimental cohort design to implement standard and enhanced (single condition: extended discussion, test/feedback) consent procedures. Participants completed a 21-item informed consent comprehension assessment instrument.

RESULTS

After standard consent procedures, mean comprehension scores were 11.36, 13.64, and 13.43 (score range: 0-21) among adolescents, young adults, and parents, respectively. About 6.2% of adolescents, 19.6% of young adults, and 21.4% of parents answered ≥ 80% of the questions correctly. After the enhanced procedures, comprehension scores (15.87 adolescents, 17.81 young adults, and 16.77 parents) and proportions answering ≥ 80% of the questions correctly (44.9% adolescents, 76.8% young adults, and 64.3% parents) increased significantly. Regression analysis indicated statistically significant differences (p < .001) in comprehension scores between the enhanced and standard groups (β = 3.87 adolescents, β = 4.03 young adults, and β = 3.60 parents) after controlling for sociodemographic factors.

DISCUSSION

Enhancing consent procedures with extended discussions, quizzes, and additional explanation where understanding is inadequate is a promising approach for improving comprehension. However, poorer comprehension among adolescents compared to young adults and parents underscores the need for research to identify additional approaches to improve understanding.

The effectiveness and acceptability of multimedia information when recruiting children and young people to trials: the TRECA meta-analysis of SWATs

Background

The information provided to potential trial participants plays a crucial role in their decision-making. Printed participant information sheets for trials have received recurrent criticism as being too long and technical, unappealing and hard to navigate. An alternative is to provide information through multimedia (text, animations, video, audio, diagrams and photos). However, there is limited evidence on the effects of multimedia participant information on research recruitment rates, particularly in children and young people.

Objectives

The study objectives were as follows: 1. to develop template multimedia information resources through participatory design, for use when recruiting children and young people to trials 2. to evaluate the multimedia information resources in a series of Studies Within A Trial, to test their effects on recruitment and retention rates, and participant decision-making, by comparing the provision of multimedia information resources instead of printed participant information sheets, and comparing the provision of multimedia information resources in addition to printed participant information sheets.

Design

Two-phase study: 1. multimedia information resources development including qualitative study; user testing study; readability metrics; enhanced patient and public involvement 2. multimedia information resources' evaluation comprising Studies Within A Trial undertaken within host trials recruiting children and young people.

Setting

United Kingdom trials involving patients aged under 18.

Participants

Development phase: n = 120 (children and young people, parents, clinicians, trial personnel). Evaluation phase: n = 1906 (children and young people being asked to take part in trials).

Interventions

Multimedia information resources (comprising text, audio, 'talking heads' video, trial-specific and trial-generic animations). Printed participant information sheets.

Main outcome measures

Primary outcome: trial recruitment rate comparing multimedia information resource-only with printed participant information sheet-only provision. Secondary outcomes: trial recruitment rate comparing combined multimedia information resource and printed participant information sheet with printed participant information sheet-only provision; trial retention rate; quality of participant decision-making. Results for each trial were calculated and combined in a two-stage random-effects meta-analysis.

Results

Phase 1 generated two multimedia information resource templates: (1) for children aged 6-11 years; (2) for children aged 12-18 years and parents. In the Phase 2 Studies Within A Trial the multimedia information resources improved trial recruitment, when compared to printed information alone [odds ratio (OR) = 1.54; 95% confidence interval (CI) 1.05 to 2.28; p = 0.03; I2 = 0%]. When printed participant information sheet-only provision was compared to combined multimedia information resource and printed participant information sheet provision, there was no effect on trial recruitment (OR = 0.89; 95% CI 0.53 to 1.50; I2 = 0%). There were no differences between multimedia information resource and printed participant information sheet on trial retention or participant decision-making quality. In a study within a hypothetical trial setting, multimedia information resource-only provision produced higher ratings of 'information was easy to understand' (Z = 3.03; p = 0.003) and 'I had confidence in decision-making' (Z = 2.00; p = 0.044) than printed participant information sheet-only provision.

Limitations

It was not possible to include data from three Studies Within A Trial in the meta-analysis due to limited sample size, and questionnaire return rates were low, which reduced the strength of the findings.

Conclusions

Use of multimedia information increased the rate of recruitment to trials involving children and young people compared to standard patient information sheets.

Future work

There should be further evaluation of the effects of multimedia information on recruitment to trials involving children and young people. It would be valuable to assess any impacts of multimedia information resources on communication between trial recruiters, children and young people, and parents.

Ethical Aspects of Involving Adolescents in HIV Research: A Systematic Review of the Empiric Literature

OBJECTIVE

To evaluate the ethics of involving adolescents in HIV research, we conducted a systematic review of the empiric literature.

METHODS

Electronic databases Ovid Medline, Embase, and CINAHL were systematically searched using controlled vocabulary terms related to ethics, HIV, specified age groups, and empiric research studies. We reviewed titles and abstracts, including studies that collected qualitative or quantitative data, evaluated ethical issues in HIV research, and included adolescents. Studies were appraised for quality, data were extracted, and studies were analyzed using narrative synthesis.

RESULTS

We included 41 studies: 24 qualitative, 11 quantitative, 6 mixed methods; 22 from high-income countries (HIC), 18 from low- or middle-income countries (LMIC), and 1 from both HIC and LMIC. Adolescent, parent, and community perspectives assert the benefits of involving minors in HIV research. Participants in LMIC expressed mixed views regarding parental consent requirements and confidentiality, given adolescents' both increasing autonomy and continued need for adult support. In studies in HIC, sexual or gender minority youth would not participate in research if parental consent were required or if there were confidentiality concerns. There was variation in the comprehension of research concepts, but adolescents generally demonstrated good comprehension of informed consent. Informed consent processes can be improved to increase comprehension and study accessibility. Vulnerable participants face complex social barriers that should be considered in study design.

CONCLUSIONS

Data support the inclusion of adolescents in HIV research. Empiric research can inform consent processes and procedural safeguards to ensure appropriate access.

Digitalizing the Clinical Research Informed Consent Process: Assessing the Participant Experience in Comparison With Traditional Paper-Based Methods

PURPOSE

Consent processes are critical for clinical care and research and may benefit from incorporating digital strategies. We compared an electronic informed consent (eIC) option to paper consent across four outcomes: (1) technology burden, (2) protocol comprehension, (3) participant agency (ability to self-advocate), and (4) completion of required document fields.

METHODS

We assessed participant experience with eIC processes compared with traditional paper-based consenting using surveys and compared completeness of required fields, over 3 years (2019-2021). Participants who consented to a clinical trial at a large academic cancer center via paper or eIC were invited to either pre-COVID-19 pandemic survey 1 (technology burden) or intrapandemic survey 2 (comprehension and agency). Consent document completeness was assessed via electronic health records.

RESULTS

On survey 1, 83% of participants (n = 777) indicated eIC was easy or very easy to use; discomfort with technology overall was not correlated with discomfort using eIC. For survey 2, eIC (n = 262) and paper consenters (n = 193) had similar comprehension scores. All participants responded favorably to at least five of six agency statements; however, eIC generated a higher proportion of positive free-text comments (P < .05), with themes such as thoroughness of the discussion and consenter professionalism. eIC use yielded no completeness errors across 235 consents versus 6.4% for paper (P < .001).

CONCLUSION

Our findings suggest that eIC when compared with paper (1) did not increase technology burden, (2) supported comparable comprehension, (3) upheld key elements of participant agency, and (4) increased completion of mandatory consent fields. The results support a broader call for organizations to offer eIC for clinical research discussions to enhance the overall participant experience and increase the completeness of the consent process.

Ethical Aspects of Personalized Research and Management of Systemic Inflammatory Response Syndrome (SIRS) in Children

Systemic inflammatory response syndrome (SIRS) is a life-threatening condition with nonspecific symptoms. Because of that, defining a targeted therapy against SIRS in children and adults remains a challenge. The identification of diagnostic patterns from individualized immuneprofiling can lead to development of a personalized therapy. The aim of this study was to identify and analyze ethical issues associated with personalized research and therapy for SIRS in pediatric populations. We conducted an ethical analysis based on a principled approach according to Beauchamp and Childress' four bioethical principles. Relevant information for the research objectives was extracted from a systematic literature review conducted in the scientific databases PubMed, Embase and Web of Science. We searched for pertinent themes dealing with at least one of the four bioethical principles: "autonomy", "non-maleficence", "beneficence" and "justice". 48 publications that met the research objectives were included in the thorough analysis, structured and discussed in a narrative synthesis. From the analysis of the results, it has emerged that traditional paradigms of patient's autonomy and physician paternalism need to be reexamined in pediatric research. Standard information procedures and models of informed consent should be reconsidered as they do not accommodate the complexities of pediatric omics research.

Co-creation of information materials within the assent process: From theory to practice

INTRODUCTION

The informed consent process is key to safeguarding the autonomy of the participant in medical research. For this process to be valid, the information presented to the potential participant should meet their needs and be understood by them. The i-CONSENT project has developed 'Guidelines for adapting the informed consent process in clinical trials' which aim to improve informed consent so that they are easier to understand and better adapted to the needs and preferences of the target population. The best way to tailor information to the characteristics and preferences of the target population is to involve the community itself.

METHODS

Following guidelines developed by i-CONSENT, assent materials were co-created for a mock clinical trial of the human papillomavirus vaccine in adolescents. During the process, two design thinking sessions were conducted involving a total of 10 children and 5 parents. The objectives of the sessions were to find out the children's opinion of the informed consent (assent in their case) process in clinical trials, identify the parts that were most difficult to understand and alternatives for their presentation and wording, identify the preferred formats for receiving the information and the main characteristics of these formats, design a video explaining the clinical trial and evaluate a tool for assessing comprehension.

RESULTS

Assent materials were co-created in three formats: a web-based material following a layered approach; a video in story format; a pdf document with an innovative way of presenting information compared to traditional assent documents. In addition, the Comprehension of Assent Questionnaire was co-designed, based on the Quality of Informed Consent questionnaire.

CONCLUSION

The design thinking methodology has proven to be an easy and useful tool for involving children in designing information tailored to their needs and preferences.

PATIENT OR PUBLIC CONTRIBUTION

A sample of the target population participated in the design and piloting of the materials created using design thinking methodology. In addition, patient representatives participated in the design and evaluation of the guidelines developed by the i-CONSENT project that were followed for the development of the materials in this study.

Electronic informed consent criteria for research ethics review: a scoping review

Background

The research shows a growing trend in using an electronic platform to supplement or replace traditional paper-based informed consent processes. Instead of the traditionally written informed consent document, electronic informed consent (eConsent) may be used to assess the research subject’s comprehension of the information presented. By doing so, respect for persons as one of the research ethical principles can be upheld. Furthermore, these electronic methods may reduce potential airborne infection exposures, particularly during the pandemic, thereby adhering to the beneficence and nonmaleficence principle. This scoping review aims to identify the ethics related criteria that have been included in electronic informed consent processes and to synthesize and map these criteria to research ethics principles, in order to identify the gaps, if any, in current electronic informed consent processes.

Methods

The search was performed based on internet search and three main databases: PubMed, SCOPUS and EBSCO. PRISMA Extension for Scoping Reviews (PRISMA-ScR): Checklist and Explanation guideline was used to report this work.

Results

Of 34 studies that met the inclusion criteria, 242 essential original constructs were collated, and 7 concepts were derived. Digital content showed the highest percentage of collated original constructs (27%, n = 65) followed by accessibility (24%, n = 56), comprehension engagement (18%, n = 43), autonomy (14%, n = 34), confidentiality (11%, n = 25), language (5%, n = 13), and parental consent (1%, n = 2). Twenty-five new items were synthesized for eConsent criteria which may provide guidance for ethical review of research involving eConsent.

Conclusion

The current study adds significant value to the corpus of knowledge in research ethics by providing ethical criteria on electronic informed consent based on evidence-based data. The new synthesized items in the criteria can be readily used as an initial guide by the IRB/REC members during a review process on electronic informed consent and useful to the future preparation of a checklist.

Replacing Paper Informed Consent with Electronic Informed Consent for Research in Academic Medical Centers: A Scoping Review

Although experts have identified benefits to replacing paper with electronic consent (eConsent) for research, a comprehensive understanding of strategies to overcome barriers to adoption is unknown. To address this gap, we performed a scoping review of the literature describing eConsent in academic medical centers. Of 69 studies that met inclusion criteria, 81% (n=56) addressed ethical, legal, and social issues; 67% (n=46) described user interface/user experience considerations; 39% (n=27) compared electronic versus paper approaches; 33% (n=23) discussed approaches to enterprise scalability; and 25% (n=17) described changes to consent elections. Findings indicate a lack of a leading commercial eConsent vendor, as articles described a myriad of homegrown systems and extensions of vendor EHR patient portals. Opportunities appear to exist for researchers and commercial software vendors to develop eConsent approaches that address the five critical areas identified in this review.

Improving assent in health research: a rapid systematic review

Background

Enrolment in a research study requires the participant’s informed consent. In the case of minors, informed consent of the respective legal guardian is obtained in conjunction with informed assent of the underage p

articipant. Since comprehension of the information provided may be limited, effective interventions to improve understanding should be identified. Thus, it is the objective of this study to review quantitative studies that tested interventions to improve the understanding of information provided during assent processes in health research. The studied population consisted of minors that participated or were willing to participate in research. The primary outcome was the level of comprehension after intervention.

Methods

A systematic search was conducted in eleven databases including regional databases: PubMed, Web of Science, ERIC, PsycINFO, CINAHL, POPLINE, AIM, LILACS, WPRIM, IMSEAR, and IMEMR and included references from inception of the database until July 2018 except PubMed which spanned the period from May 2013 to July 2018. Search terms focused on Informed Consent/Assent, Minors, and Comprehension. To complement the search, reference lists of retrieved publications were additionally searched. We included all quantitative studies that were conducted in minors, tested an intervention, covered assent processes in health research, and assessed comprehension. One reviewer screened titles, abstracts, and full-texts to determine eligibility and collected data on study design, population, intervention, methods, outcome, and for critical appraisal. Interventions comprised enhanced paper forms, interspersed questions, multimedia format, and others.

Results

Out of 7089 studies initially identified, 19 studies comprising 2805 participants and conducted in seven countries were included in the review. Fourteen studies (74 %) tested an intervention against control and ten (53 %) were randomized controlled trials. Heterogeneous methodology as well as incomplete outcome and statistical reporting impaired the reliability of the collected data. Positive effects were suggested for use of enhanced paper forms, interspersed questions, use of pie charts, and organizational factors.

Conclusions

Improving assent in health research is an under-researched area with little reliable evidence. While some interventions are proposed to improve understanding in assent processes, further investigation is necessary to be able to give evidence-based recommendations.

Supporting children and young people when making decisions about joining clinical trials: qualitative study to inform multimedia website development

OBJECTIVES

To understand stakeholders' views regarding the content and design of paediatric clinical trial multimedia websites. To describe how this knowledge informed the development of the multimedia websites.

DESIGN

Qualitative study comprising two rounds of interviews or focus groups, with thematic analysis of interview transcripts.

PARTICIPANTS

Sixty-two people (21 children and young people with long-term health conditions, 24 parents and 17 professionals).

SETTING

One UK children's hospital and one UK Young Persons' Advisory Group.

RESULTS

When asked what was important in deciding whether to join a trial, children, young people and parents prioritised information about what participation would involve, what the trial was testing, potential benefits and risks of participation and knowing they could leave the trial if they later changed their minds. Young people and parents trusted trial teams to follow regulatory and quality requirements and therefore did not think such information was a priority for the websites, although logos of trusted organisations could lend credibility. Professionals largely concurred with these views. Children and young people advised on the importance of designing the multimedia website to ensure its appearance, tone and wording suited the intended audience and on using animated characters to facilitate children's engagement.

CONCLUSIONS

Our study provides insights into the information that families value when deciding about healthcare trial participation. It provides guidance on the design of information resources to appeal to children and young people, while also being acceptable to parents and professionals who are often gatekeepers of children's access to information. Our findings will be of use to others developing similar multimedia websites. We report specific information needs and new visual preferences that are not usually addressed in printed trial information. Our work illustrates what qualitative research and participatory design practices can contribute to the development of information resources more generally.

Assent in Pediatric Patients

AIM

To report an analysis of the concept of pediatric assent.

BACKGROUND

The concept of assent is poorly defined in current literature which may lead to potentially flawed practices in obtaining pediatric assent.

DESIGN

The Walker and Avant (2011) method is used to provide clarity to the concept of pediatric assent.

DATA SOURCES

Data were collected from PubMed, Academic Search Premier, PhilPapers, Wikipedia, and Google.

REVIEW METHODS

Data were collected from 2014 to 2015. Twenty-three sources published between 2011 and 2015, nine sources published between 2003 and 2009, the Belmont Report (1979), and the American Academy of Pediatrics' report (1995) were included for pertinent contributions to this multidisciplinary concept analysis.

RESULTS

Elements of assent include a patient's thoughtful review of the proposed treatment and rational decision in choosing the best course of action. There may be social, familial, and cognitive development factors influencing this process.

CONCLUSION

This framework uses nurses' knowledge of cognitive development and ethics to inform practice. Assent is respectful of minor patients and ensures their rights are protected. Policies and procedures can be developed to incorporate assent, researchers have a stronger conceptual base, and educators can train nurses to help pediatric patients develop medical decision making skills.
