Comic strips help children understand medical research: targeting the informed consent procedure to children's needs

Experiences of pediatric cancer patients (age 12-18 years) with extensive germline sequencing for cancer predisposition: a qualitative study

This study explored the experiences and needs of adolescents, ranging from 12 to 18 years old, who have recently been diagnosed with cancer and participated in a nationwide germline genetic sequencing study within the context of pediatric oncology. The 21 adolescents in this qualitative interview study viewed genetic sequencing as an integral part of their cancer journey. They often characterized germline sequencing as "good-to-know" without specifying immediate utility. While the adolescents comprehended the significance of germline genetic sequencing, they were less focused on its potential long-term implications. Adolescents expressed a strong desire to be actively engaged in decisions related to genetics. They advocated for a participatory role in genetic decision-making from a young age onwards. They recommended that re-consent should be sought before re-analysis of their genetic data is performed and believe that patients should have the opportunity to provide (re-)consent once they reach adulthood. Moreover, the adolescents emphasized the importance of developing counseling materials that are not only concise but also visually attractive. In conclusion, this study underscores the positive perception that adolescents diagnosed with cancer hold regarding germline genetic sequencing. They articulate a strong interest in being actively involved in genetic decision-making. To address these articulated needs and preferences, we recommend the development of visually engaging counseling materials. These materials should effectively convey both the immediate and long-term implications of genetic sequencing, enabling adolescents with cancer to make informed decisions about genetic sequencing.

Developing a Family Resource: Considerations for Family Member Research Participation

When individuals participate in health care research, the choice often affects the entire family. Researchers are responsible for protecting participants and minimizing any burdens the research may place on them. Resources to educate potential study participants about these issues from a family perspective are lacking. A family-focused, evidence-based resource was created for individuals and families to prompt discussion prior to their consenting to enrollment in research. The resource includes key relevant questions to consider related to their study participation and was revised based on input from family nurse scientists and a hospital-based family advisory group. This resource raises awareness of the importance of employing a family lens when designing research and during the recruitment and enrollment of participants. Adopting a family lens in health care research will support the participant's ability to make an informed choice regarding participation and may ultimately enhance the experience of participants and their families and study outcomes.

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.

Improving comprehension, recall and attention using multimedia-informed assent among pediatric oncology patients: A comparative randomized controlled trial

BACKGROUND

Assent should be obtained in all children involved in research in keeping with their level of maturity. Traditional assent forms contain too much information and are difficult to read. The study aimed to identify an effective tool to enhance children's comprehension during the assent process and focused on those with cancer who are likely more engaged in research involving greater than minimal risk.

METHODS

In all, 116 children with cancer were randomized to receive either a paper-based assent document or a multimedia-based assent document. Open-ended and multiple-choice questions were used to assess comprehension and recall. Time spent on the documents and children's behavior during the assent process was recorded to determine their attention and satisfaction.

RESULTS

Children randomized to a multimedia-based assent document achieved significant higher comprehension and recall assessment scores (p-values <.001). The high score achievement significantly correlated with the child's age with adjusted odds ratio (OR) of 1.90 (p-value <.001; 95% confidence interval [CI]: 1.35-2.66) for comprehension assessment and 1.59 (p-value .001; 95% CI: 1.20-2.12) for recall assessment. Children randomized to a multimedia-based assent document had significant longer time spent on the document (p-value .001) with less numbers of inattention (p-value <.001) and expressed more signs of enjoyment during the assent process (p-values <.001).

CONCLUSION

Multimedia-based assent document successfully enhanced comprehension, recall, and attention with more satisfaction compared with a traditional paper-based document among children with cancer. This approach may be considered as an alternative format for children engaging in research involving greater than minimal risk.

DigiKnowIt News: Educating youth about pediatric clinical trials using an interactive, multimedia educational website

Pediatric clinical trials allow for the testing of appropriate and effective treatments for children. However, some challenges exist with recruitment. This study examined the effectiveness of DigiKnowIt News, an interactive, multimedia website (which includes activities, videos, and comic books) designed to educate children about clinical trials. A randomized controlled trial was conducted in 2018 with 91 participants (M age = 10.92 years; SD = 2.06). Participants were randomly assigned to intervention or wait-list control groups and completed questionnaires at pretest and posttest (1 week later) about their knowledge, attitudes, beliefs about clinical trials, and self-efficacy for participating in clinical trials. Participants in the intervention group received access to DigiKnowIt News between pretest and posttest and completed a satisfaction questionnaire at posttest. At the end of the study, participants in the wait-list control group were offered the option to use the website and complete a satisfaction questionnaire. At posttest, participants in the intervention group, compared to participants in the wait-list control group, had more knowledge about clinical trials and more reported confidence for participating in clinical trials. Participants reported high levels of satisfaction with DigiKnowIt News. The findings suggest that an educational website can improve factors related to increasing rates of participation in clinical trials.

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.

A didactic approach to presenting verbal and visual information to children participating in research protocols: the comic book informed assent

OBJECTIVE

When children participate in research protocols, consent (by a parent or legal guardian) and assent (by the children) must be given. Understanding research protocols can be challenging for an adult and even more difficult for a child. The aim of this study was to describe the development of a comic book created to facilitate children's understanding of informed assent with clear and simple language.

METHODS

Five researchers with scores above seven according to the Fehring criteria developed the comic book, avoiding the use of technical terminology. Twenty children between 7 and 12 years old, and enrolled in a larger study, responded using a Likert scale and questions about the clarity of texts and illustrations. The final version met National Health System Resolutions (Resoluções do Conselho Nacional da Saúde - CNS n° 196/1996 and 466/2012).

RESULTS

The comic book assent presents a short story containing information about a real study: the invitation to participate, objectives, methods, instruments, procedures, risks, benefits, and the researchers' contact information. Most of the participants answered that they perceived the content of the text to be "Excellent" (40%) and "Very good" (40%), and the illustrations were perceived as "Excellent" (45%) and "Very good" (55%).

CONCLUSION

The construction of a simple and clear model of informed assent is possible, and this model should be used in experiments with children.

Clinical research with adolescents: barriers and how to overcome them

PURPOSE OF REVIEW

This review aims to emphasize the importance of including adolescents in research, outline current standards and evaluate barriers that prevent adolescent research. We also hope to provide some guidance and call for much needed additional direction in the field.

RECENT FINDINGS

The absolute necessity for including adolescents in research has been an area of focus within the community of adolescent providers and care takers. Recent policy and support from major organizations has emphasized the importance of including this population in research but also pointed out many of the complexities.

SUMMARY

Adolescent research is imperative to guiding policy and promoting evidence-based care. Current standards provide both guidance and barriers, yet more research is needed to further guide conduct of ethical research in this population.

When to invest in clinical guidelines for children? A practice oriented tool to facilitate decision-making

RATIONALE, AIMS AND OBJECTIVES

Children are not just small adults; they need to be diagnosed and treated in the context of their rapid growth and development. However, in guideline development, children's needs and interests are still overlooked. This study aims (1) to develop a tool that could stimulate guideline developers to take children into account on a more structural basis and (2) to explore how to facilitate children's participation in the process of guideline development.

METHODS

The method used was a three-phase multimethod sequential design. Professionals involved in guideline development participated in interviews (n = 12), filled in a questionnaire (n = 60) and/or participated in the focus group meeting (n = 11).

RESULTS

This study results in a comprehensive understanding of the considerations that professionals take into account when deciding whether guidelines need to apply to children specifically. This resulted in a tool that assists guideline developers to make this assessment more accurately. It takes the form of a flowchart that guides users through a series of critical questions.

CONCLUSIONS

The flowchart reminds guideline developers to consider children as a particular patient population when prioritizing and demarcating new guideline topics. It will help to ensure that clinical guidelines address children's unique health care needs and perspectives. Facilitating children's and parents' participation in the process of guideline development is perceived as challenging; nevertheless, it should be the next step in making paediatric guidelines more child-centred and family-centred.

Using media to improve the informed consent process for youth undergoing pediatric endoscopy and their parents

Background and study aims Youth undergoing pediatric endoscopic procedures and their parents demonstrate suboptimal comprehension of the informed consent (IC) process. We developed informational videos discussing key IC elements for pediatric endoscopy and evaluated their effects on youth and parental comprehension of the IC process. Patients and methods A randomized controlled trial of the video intervention was performed among youth undergoing endoscopy and their parents at an academic children's hospital. Randomization occurred at the time of enrollment using permutated blocks. Following the IC process with the proceduralist, subjects underwent structured interviews to assess IC comprehension. An Informed Consent Overall Score (ICOS: range 0 - 4) for comprehension was calculated. Results Seventy-seven pairs of children and their parents participated. Intervention recipients (N = 37 pairs) demonstrated higher ICOS scores as compared to control counterparts (mean (standard deviation): 3.6 (0.7) v. 2.9 (0.9), intervention v. control parents, P < 0.0001 and 2.7 (1.1) v. 1.7 (1.1), intervention v. control youth, P < 0.0001). Conclusions A media intervention addressing key elements of the IC process for pediatric endoscopy was effective in improving comprehension of IC for youth undergoing endoscopic procedures and their parents.

Perspectives of adolescents on decision making about participation in a biobank study: a pilot study

OBJECTIVES

To be able to truly involve adolescents in decision making about clinical research participation, we need more insight in the perspective of adolescents themselves. To this end, adolescents in an ongoing biobank study were consulted to test a tentative decision assessment tool.

METHODS

The perspectives of adolescents (n=8) concerning participation in decision making for research participation were explored in interviews with a tentative tool, which covered six topics: information material usage, understanding, disease perceptions, anxiety, decision-making process and role sharing.

RESULTS

All adolescents unequivocally expressed the desire to be involved in decision making, but also wanted advice from their parents. The extent of the preferred role of adolescent versus parents varied between individuals. In decision making, adolescents relied on parents for information. More than half hardly used the information material.

CONCLUSIONS

Adolescents in our study preferred a shared decision-making process. The extent of sharing varied between individuals. The decision assessment tool was a fruitful starting point to discuss adolescents' perspectives and may aid in tailoring the situation to the individual to achieve optimal participation practices.

IMPLICATIONS

Consulting adolescents about their preferences concerning decision making using the tool will facilitate tailoring of the shared decision-making process and optimising the developing autonomy of minors.

Understanding parental refusal of permission for child participation in surgical prospective trials

PURPOSE

The success of prospective randomized trials relies on voluntary participation, which has been perceived as a barrier for successful trials in children who rely on parental permission. We sought to identify the reasons parents decline child participation to understand potential limitations in the consent process.

METHODS

A prospective observational study was conducted in 92 patients asked to participate in prospective randomized trials between 2012 and 2015. Parental reasons for refusal were documented.

RESULTS

The 92 refusals were distributed between studies investigating the management of circumcision, gastroschisis, pectus excavatum, appendicitis, pyloric stenosis, undescended testicles, abdominal abscess and gastroesophageal reflux. Reasons for refusal included preference of treatment path (37 %), inability to follow up (21 %), unspecified resistance to participate in research (18 %), preference to maintain independent surgeon decision (16 %), and desire for historically standard treatment (8 %). Of the families who opted to pursue a specific treatment arm rather than randomization, 35 % had prior experience with that treatment, 32 % had researched the procedure, 18 % wished to pursue the minimal intervention and 15 % did not specify.

CONCLUSIONS

Parental preference of therapy is the most common reason for refusal of study participation. This variable could be influenced with more effective explanation of study rationale and existing equipoise.

Adolescents with substance use disorder and assent/consent: Empirical data on understanding biobank risks in genomic research

OBJECTIVE

This study assessed whether a customized disclosure form increases understanding for adolescents with substance use disorder (SUD) when compared to a standard disclosure for genomic addiction research.

METHOD

We gathered empirical data from adolescents with SUD, family members, former patients followed since adolescence, and community counterparts. The study was conducted in four stages. Stage 1: national experts (n=32) identified current, future, speculative risks of broadly shared biobanks. Stage 2 assessed participants' (n=181) understanding of current risks as a prerequisite for rating saliency of risks via a Visual Analog Scale. Salient risks were incorporated into a customized disclosure form. Stage 3 compared the understanding of customized disclosure by participants (n=165) at baseline; all groups scored comparably. Stage 4 conducted a direct comparison of the standard disclosure to standard disclosure plus customized disclosure (n=195). Independent t-tests compared understanding in those receiving the standard disclosure to standard disclosure plus customized disclosure within 6 groups.

RESULTS

The customized disclosure significantly improved understanding in adolescent patients (p=0.002) and parents of patients (p=0.006) to the level of their counterparts. The customized disclosure also significantly improved understanding in siblings of former patients (p=0.034). Understanding of standard disclosure in patients versus controls was significantly different (p=0.005). The groups receiving the customized disclosure scored significantly higher. Understanding of the standard disclosure plus customized disclosure in patients versus controls was not significantly different.

CONCLUSION

Adolescents with addictions understand the risks of participating in genomic addiction research as well as their community counterparts when information provided is salient to them.

Children's self reported discomforts as participants in clinical research

INTRODUCTION

There is little empirical evidence on children's subjective experiences of discomfort during clinical research procedures. Therefore, Institutional Review Boards have limited empirical information to guide their decision-making on discomforts for children in clinical research. To get more insight into what children's discomforts are during clinical research procedures, we interviewed a group of children on this topic and also asked for suggestions to reduce possible discomforts.

MATERIALS AND METHODS

Forty-six children (aged 6-18) participating in clinical research studies (including needle-related procedures, food provocation tests, MRI scans, pulmonary function tests, questionnaires) were interviewed about their experiences during the research procedures. Thematic analysis was used to analyze the interviews.

RESULTS

The discomforts of the interviewed children could be divided into two main groups: physical and mental discomforts. The majority experienced physical discomforts during the research procedures: pain, shortness of breath, nausea, itchiness, and feeling hungry, which were often caused by needle procedures, some pulmonary procedures, and food provocation tests. Mental discomforts included anxiousness because of anticipated pain and not knowing what to expect from a research procedure, boredom and tiredness during lengthy research procedures and waiting, and embarrassment during Tanner staging. Children's suggestions to reduce the discomforts of the research procedures were providing distraction (e.g. watching a movie or listening to music), providing age-appropriate information and shortening the duration of lengthy procedures.

DISCUSSION

Our study shows that children can experience various discomforts during research procedures, and it provides information about how these discomforts can be reduced according to them. Further research is needed with larger samples to study the number of children that experience these mentioned discomforts during research procedures in a quantitative way.
