Anatomical human body donation in South Africa: Inconsistencies of informed consent

INTRODUCTION

Informed consent is critical for maintaining the ethical standards associated with the utilization of human donor bodies by tertiary education institutions. Body donation programs undertake the responsibility for procuring human donor bodies for didactic and research purposes. However, its processes require scrutiny regarding best practice guidelines and the South African National Health Act (SA-NHA) (2013). Moreover, acknowledging and addressing the current perceptions of human body donation are indispensable in bridging the gap between academia and society. This study aimed to compare informed consent documentation and procedures across South African tertiary education institutions and their affiliated human body donation programs (HBDP) in accordance with international guidelines. The findings were used to create a human body donation form template aligned to current international best practices for consideration by the South African HBDP.

METHODOLOGY

A review of information and consent forms collected from South Africa's eight HBDP was conducted. The analyses consisted of a broad evaluation of information provided, ranging from the terms-of-use for human donor bodies to the commitments made by HBDP to body-donors. The results were considered in conjunction with the International Federation of Associations of Anatomists and other recent publications on informed consent in HBDP.

RESULTS

Only two of the eight HBDP provided information and consent forms in more than one language. Most allowed donors to select how their bodies will be utilized - education, training and/or research. Some (6/8) made provisions for the next-of-kin to receive the cremains. Only one tertiary educational institution mentioned the occurrence of a memorial service in its documentation. An HBDF template was created aligned to current international best practices for presentation and possible adaption by SA HBDP.

DISCUSSION & CONCLUSIONS

Human body donation forms (HBDF) requires thorough examination for the promotion and sustainability of HBDP. Effective communication by employing standardized non-technical terminology conveyed in language that is understandable and native to potential donors facilitates the deliverance of informed consent. Inconsistencies regarding the use and management of bodies catalyze the weakening perception of human body donation. Thus, this process of securing informed consent for body donation should be conducted in conjunction with public awareness campaigns and underpinned by the necessary policy and legislative reform.

ChatGPT Provides Satisfactory but Occasionally Inaccurate Answers to Common Patient Hip Arthroscopy Questions

PURPOSE

To assess the ability of ChatGPT to answer common patient questions regarding hip arthroscopy, and to analyze the accuracy and appropriateness of its responses.

METHODS

Ten questions were selected from well-known patient education websites, and ChatGPT (version 3.5) responses to these questions were graded by 2 fellowship-trained hip preservation surgeons. Responses were analyzed, compared with the current literature, and graded from A to D (A being the highest, and D being the lowest) in a grading scale on the basis of the accuracy and completeness of the response. If the grading differed between the 2 surgeons, a consensus was reached. Inter-rater agreement was calculated. The readability of responses was also assessed using the Flesch-Kincaid Reading Ease Score (FRES) and Flesch-Kincaid Grade Level (FKGL).

RESULTS

Responses received the following consensus grades: A (50%, n = 5), B (30%, n = 3), C (10%, n = 1), D (10%, n = 1). Inter-rater agreement on the basis of initial individual grading was 30%. The mean FRES was 28.2 (± 9.2 standard deviation), corresponding to a college graduate level, ranging from 11.7 to 42.5. The mean FKGL was 14.4 (±1.8 standard deviation), ranging from 12.1 to 18, indicating a college student reading level.

CONCLUSIONS

ChatGPT can answer common patient questions regarding hip arthroscopy with satisfactory accuracy graded by 2 high-volume hip arthroscopists; however, incorrect information was identified in more than one instance. Caution must be observed when using ChatGPT for patient education related to hip arthroscopy.

CLINICAL RELEVANCE

Given the increasing number of hip arthroscopies being performed annually, ChatGPT has the potential to aid physicians in educating their patients about this procedure and addressing any questions they may have.

Too Anecdotal to Be True? Mechanical Turk Is Not All Bots and Bad Data: Response to Webb and Tangney (2022)

In response to Webb and Tangney (2022) we call into question the conclusion that data collected on Amazon's Mechanical Turk (MTurk) was "at best-only 2.6% valid" (p. 1). We suggest that Webb and Tangney made certain choices during the study-design and data-collection process that adversely affected the quality of the data collected. As a result, the anecdotal experience of these authors provides weak evidence that MTurk provides low-quality data as implied. In our commentary we highlight best practice recommendations and make suggestions for more effectively collecting and screening online panel data.

Ethical considerations for genetic research in low-income countries: perceptions of informed consent, data sharing, and expectations in Nicaragua

Genetic research presents numerous ethical, legal, and social implications (ELSI), particularly when the research involves collaborations between investigators in high and low-income countries. Some ELSI issues are universal, and others are specific to context and culture. This study investigates perceptions of genetic research in Nicaragua, Central America, where local and U.S. based researchers have collaborated for over a decade. A total of 43 residents from northwestern Nicaragua, a region with high mortality rates attributed to chronic kidney disease of non-traditional causes (CKDnt), were interviewed, including research participants in ongoing studies (n = 36), health professionals (n = 3), labor leaders (n = 2), and family members of research participants (n = 2). Questions focused on informed consent, data-sharing, and post-study expectations. Audio recordings of interviews conducted in Spanish were transcribed and translated into English. English transcripts were coded and analyzed using NVivo 12 software. The lack of familiarity with terms in the consent form presented a barrier to participant comprehension of key elements of the genetic research study, raising concerns about the validity of informed consent. Research participants often viewed their participation as access to health care. Health professionals emphasized the importance of long-term partnerships between foreign-based researchers and local health institutions. Leaders and family members recommended that they be informed of research studies and allowed the opportunity to consent, as they felt the benefits and risks of research also apply to them. Our findings identified genetic research practices to be improved upon in order to be more responsive to the contextual realities of collaborators living in low-resource settings.

Assessing ChatGPT's ability to answer questions pertaining to erectile dysfunction: can our patients trust it?

Erectile dysfunction (ED) is a disorder that can cause distress and shame for men suffering from it. Men with ED will often turn to online support and chat groups to ask intimate questions about their health. ChatGPT is an artificial intelligence (AI)-based software that has been trained to engage in conversation with human input. We sought to assess the accuracy, readability, and reproducibility of ChatGPT's responses to frequently asked questions regarding the diagnosis, management, and care of patients with ED. Questions pertaining to ED were derived from clinic encounters with patients as well as online chat forums. These were entered into the free ChatGPT version 3.5 during the month of August 2023. Questions were asked on two separate days from unique accounts and computers to prevent the software from memorizing responses linked to a specific user. A total of 35 questions were asked. Outcomes measured were accuracy using grading from board certified urologists, readability with the Gunning Fog Index, and reproducibility by comparing responses between days. For epidemiology of disease, the percentage of responses that were graded as "comprehensive" or "correct but inadequate" was 100% across both days. There was fair reproducibility and median readability of 15.9 (IQR 2.5). For treatment and prevention, the percentage of responses that were graded as "comprehensive" or "correct but inadequate" was 78.9%. There was poor reproducibility of responses with a median readability of 14.5 (IQR 4.0). Risks of treatment and counseling both had 100% of questions graded as "comprehensive" or "correct but inadequate." The readability score for risks of treatment was median 13.9 (IQR 1.1) and for counseling median 13.8 (IQR 0.5), with good reproducibility for both question domains. ChatGPT provides accurate answers to common patient questions pertaining to ED, although its understanding of treatment options is incomplete and responses are at a reading level too advanced for the average patient.

Incorporating Community Partner Perspectives on eHealth Technology Data Sharing Practices for the California Early Psychosis Intervention Network: Qualitative Focus Group Study With a User-Centered Design Approach

BACKGROUND

Increased use of eHealth technology and user data to drive early identification and intervention algorithms in early psychosis (EP) necessitates the implementation of ethical data use practices to increase user acceptability and trust.

OBJECTIVE

First, the study explored EP community partner perspectives on data sharing best practices, including beliefs, attitudes, and preferences for ethical data sharing and how best to present end-user license agreements (EULAs). Second, we present a test case of adopting a user-centered design approach to develop a EULA protocol consistent with community partner perspectives and priorities.

METHODS

We conducted an exploratory, qualitative, and focus group-based study exploring mental health data sharing and privacy preferences among individuals involved in delivering or receiving EP care within the California Early Psychosis Intervention Network. Key themes were identified through a content analysis of focus group transcripts. Additionally, we conducted workshops using a user-centered design approach to develop a EULA that addresses participant priorities.

RESULTS

In total, 24 participants took part in the study (14 EP providers, 6 clients, and 4 family members). Participants reported being receptive to data sharing despite being acutely aware of widespread third-party sharing across digital domains, the risk of breaches, and motives hidden in the legal language of EULAs. Consequently, they reported feeling a loss of control and a lack of protection over their data. Participants indicated these concerns could be mitigated through user-level control for data sharing with third parties and an understandable, transparent EULA, including multiple presentation modalities, text at no more than an eighth-grade reading level, and a clear definition of key terms. These findings were successfully integrated into the development of a EULA and data opt-in process that resulted in 88.1% (421/478) of clients who reviewed the video agreeing to share data.

CONCLUSIONS

Many of the factors considered pertinent to informing data sharing practices in a mental health setting are consistent among clients, family members, and providers delivering or receiving EP care. These community partners' priorities can be successfully incorporated into developing EULA practices that can lead to high voluntary data sharing rates.

Developing a digital informed consent app: opportunities and challenges of a new format to inform and obtain consent in public health research

BACKGROUND

Informed consent procedures for large population-based cohort studies should be comprehensive and easy-to-use. This is particularly challenging when participants from different socio-economic groups and multicultural ethnic backgrounds are involved. Recently, more and more studies have tried to use multimedia in informed consent procedures. We describe the development and testing of a digital informed consent app and elaborate on whether this may contribute to a comprehensive and practical procedure to obtain informed consent for public health research.

METHODS

In a sample of parents with young children, we used a mixed method approach to study the user experience of an informed consent app and evaluate whether it can be used to adequately inform people and register their consent. Through semi-structured interviews we investigated participants' experiences with and opinions about the app, with a special focus on comprehensibility of the content and the usability of the app. Information retention questions were asked to evaluate to what extent participants could recall key aspects of the provided study information.

RESULTS

The 30 participants in this study used the app between 4 and 15 min to give their consent. Overall, they found the app well-designed, informative and easy to use. To learn more about the study for which informed consent is asked, most of the participants chose to watch the animated film, which was generally found to convey information in a clear manner. The identification process was met with mixed reactions, with some feeling it as a secure way to give consent, while for others it contradicted their view of using data anonymously. Information retention questions showed that while all participants remembered various aspects of the study, fewer than half answered all four questions satisfactorily.

CONCLUSION

Our study shows that a well-designed informed consent app can be an effective tool to inform eligible participants and to record consents. Still, some issues remain, including trust barriers towards the identification procedure and lack of information retention in some participants. When implementing consent procedures that incorporate digital formats, it may be beneficial to also invest in a complementary face-to-face recruitment approach.

Regulatory compliance and readability of informed consent forms in industry-sponsored drug development clinical trials

BACKGROUND/AIMS

An informed consent form is essential in drug development clinical trials. This study aimed to evaluate regulatory compliance and readability of informed consent forms currently being used in industry-sponsored drug development clinical trials.

METHODS

This descriptive, cross-sectional study evaluated the informed consent forms of industry-sponsored drug development clinical trials conducted at the Faculty of Medicine, Chiang Mai University, between 2019 and 2020. The informed consent form's compliance with the three major ethical guidelines and regulations (i.e. International Council for Harmonization of Technical Requirements for Pharmaceuticals for Human Use E6(R2) Good Clinical Practice; Declaration of Helsinki; and the revised Common Rule) were analyzed. The document length and the readability scores (using Flesch Reading Ease and Flesch-Kincaid Reading Grade) were assessed.

RESULTS

Of 64 reviewed informed consent forms, the average page length was 22.0 ± 7.4 pages. More than half of their length was mainly devoted to three elements: trial procedures (22.9%), risks and discomforts (19.1%), and confidentiality and the limit of confidentiality (10.1%). Although most of the required elements of the informed consent form content were included in most informed consent forms, we identified four elements with often missing information in the form: aspects of research that are experimental (n = 43, 67.2%), involvement of whole-genome sequencing (n = 35, 54.7%), commercial profit sharing (n = 31, 48.4%), and posttrial provisions (n = 28, 43.8%).

CONCLUSION

The informed consent forms in industry-sponsored drug development clinical trials were long but incomplete. Our findings draw attention to ongoing challenges in industry-sponsored drug development clinical trials, where deficient informed consent form quality continues to exist.

Navigating the perils and pitfalls throughout the consent process in hematopoietic cell transplantation

Hematopoietic cell transplantation (HCT) is a complex treatment used in malignancies and some non-malignant diseases. The informed consent process for HCT can also be complex due to patient- and process-related barriers. The informed consent process needs to be a dynamic and ongoing process, not simply a checklist. As a result of the realities of HCT, we highlight some potential pitfalls to the informed consent process including uncertainty, sociocultural and communication barriers, and decisional regret. The purpose of this comprehensive review is to highlight unique situations which can result in failure of the informed consent process. We also offer potential solutions to these pitfalls, primarily making the informed consent more patient focused through dynamic and continuous processes to mitigate decisional regret.

Patients’ knowledge about their involvement in clinical trials. A non-randomized controlled trial

Background

Nowadays, good clinical practice should be established in human research. Patient’s rights and autonomy must be respected above the interest of the researcher, making mandatory to raise patient’s awareness on the implications of participating in a clinical study. Contrary to popular belief, this is not always the case. This means that, after signing the informed consent form, some patients have difficulties understanding their responsibilities as participants.

Materials and methods

This study is a prospective, multicenter, non-randomized controlled trial comparative survey conducted on patients enrolled in a clinical trial to evaluate and improve their understanding after an educational intervention was applied to the research staff.

Results

Females were underrepresented in the clinical trials performed in this study, 21.5%. Most of the participants had a low educational level (74.4%). Around 5 and 10% of the research participants were not aware they were part of a clinical study, and more 24% just trusted in the medical decision to be enrolled. After the interventional education, the following items: “given time and resolution of the patient doubts” (p-value = 0.003), “enough written information” (p-value = 0.006), “explanation of the risks of participating in the study,” (p-value = 0.047) and understanding of the information provided to them showed an improvement regarding the study in which they were participating.

Conclusion

The research participants understanding of their involvement in clinical trials is limited. An educational intervention on the research team can improve the process of empowerment and transit of information.

The Role of Informed Consent in Clinical and Research Settings

Informed consent plays an integral role in governing the patient-physician relationship with origins traced back to ancient Greek philosophy. The main pillars of informed consent are autonomy, integrity, respect, and care. In the last century, these notions have been codified into legislation to promote healthy patient-physician relationships. Understanding the process of informed consent is critical for patients, researchers, and medical practitioners. In this article, the authors provide a brief historical narrative of informed consent, elaborate on the process of obtaining an ethically and legally valid informed consent, and present some of the future challenges in the field.

How best to share research with study participants? A randomised crossover trial comparing a comic, lay summary, and scientific abstract

Healthcare research is traditionally published in academic papers, coded in scientific language, and locked behind paywalls - an inaccessible form for many. Sharing research results with participants and the public in an appropriate, accessible manner, is an ethical practice directed in research guidance. Evidence-based recommendations for the medium used are scant, but science communication advice advocates principles which may be fulfilled well by the medium of comics. We report a randomised crossover study conducted online, comparing participant preferences for research results shared in the medium of a comic, a traditional lay text summary, and the control approach of a scientific abstract. 1236 respondents read all three summaries and ranked their most and least preferred formats. For the most preferred summary, the comic was chosen by 716 (57.9%), lay summary by 321 (26.0%), and scientific abstract by 199 (16.1%) respondents. For the least preferred summary the scientific abstract was chosen by 614 (49.7%), lay summary by 380 (30.7%) and comic by 242 (19.6%). Review of free-text responses identified key reasons for the majority preferring the comic over the others, which included finding this easier to read and understand, more enjoyable to consume, and more satisfactory as a medium of communication.

Understanding the Use of Optimal Formatting and Plain Language When Presenting Key Information in Clinical Trials

Recent revisions to the Common Rule require that consent documents begin with a focused presentation of the study's key information that is organized to facilitate understanding. We surveyed 1,284 researchers working with older adults or individuals with Alzheimer's disease, supplemented with 60 qualitative interviews, to understand current use and barriers to using evidence-based formatting and plain language in key information. Researchers reported using formatting in 42% of their key information sections, and plain language in 63% of their key information sections. Perceived barriers included lack of knowledge, Institutional Review Board, other members of their team, and the burden associated with implementation. Education and training are required to increase adoption of the practices.

A longitudinal qualitative study to explore and optimize self-management in mild to end stage chronic kidney disease patients with limited health literacy: Perspectives of patients and health care professionals

OBJECTIVES

Limited health literacy (LHL) is associated with faster kidney deterioration. Health care professionals (HCPs) promote self-management to maintain kidney function, which is difficult for patients with LHL. Evidence lacks on perceived barriers and best strategies to optimize their self-management. Our study aims to explore experiences with and barriers for self-management from the perspectives of LHL patients and HCPs to identify strategies to optimize self-management.

METHODS

We performed a longitudinal qualitative study with semi-structured in-depth interviews and focus group discussions among CKD patients and LHL (n = 24) and HCPs (n = 37) from general practices and hospitals.

RESULTS

Four themes arose among patients: (1) CKD elusiveness, (2) suboptimal intake of knowledge (3) not taking a front-seat role, and (4) maintaining change. Among HCPs, three themes emerged: (1) not recognizing HL problems, (2) lacking effective strategies, and (3) health care barriers.

CONCLUSION

We suggest three routes to optimize self-management: providing earlier information, applying person-centered strategies to maintain changes, and improving competencies of HCPs.

PRACTICE IMPLICATIONS

HCPs need to explain CKD self-management better to prevent kidney deterioration. New interventions, based on behavioral approaches, are needed to optimize self-management. HCPs need training to improve recognition and support of LHL patients.

Communication strategies for nursing research with older adults diagnosed with schizophrenia using life course theory

PURPOSE

To explore effective communication strategies that may be used to promote efficacious research with older adults diagnosed with schizophrenia.

DESIGN

A theoretical framework of Life Course Theory was used to examine the problems of communicating in research settings with older adults diagnosed with schizophrenia and present potential effective solutions to these problems.

METHODS

Using Life Course Theory as an underpinning, a literature review was conducted regarding communication strategies/methods commonly used in psychiatric nursing. This paper deductively presents how these strategies/methods could theoretically improve nursing research with older adults diagnosed with schizophrenia.

RESULTS

Four main potential effective strategies for communication with older adults diagnosed with schizophrenia in nursing research were identified which were (1) giving space; (2) shortened intervals; (3) the use of simple, meaningful phrases; and (4) showing engagement.

CONCLUSIONS

Older adults diagnosed with schizophrenia may be given more opportunities to share their input regarding their perceptions and valuable input regarding health care systems if these effective strategies of communication are used when conducting nursing research.

CLINICAL RELEVANCE

There is a need to gain more information regarding the perceptions of older adults diagnosed with schizophrenia as they are living longer and are entering into a health care system that is often at a quandary as to how to best care for them. The strategies delineated in this paper are part of an ongoing project to co-develop a model with older adults diagnosed with schizophrenia specifically tailored to improve their health outcomes and quality of life.

Adequacy of measures of informed consent in medical practice: A systematic review

As a critical component of medical practice, it is alarming that patient informed consent does not always reflect (1) adequate information provision, (2) comprehension of provided information, and (3) a voluntary decision. Consequences of poor informed consent include low patient satisfaction, compromised treatment adherence, and litigation against medical practitioners. To ensure a well-informed, well-comprehended, and voluntary consent process, the objective and replicable measurement of these domains via psychometrically sound self-report measures is critical. This systematic review aimed to evaluate the adequacy of existing measures in terms of the extent to which they assess the three domains of informed consent, are psychometrically sound and acceptable for use by patients. Extensive searching of multiple databases (PsychINFO, PubMed, Sociological Abstracts, CINAHL, AMED) yielded 10,000 potential studies, with 16 relevant scales identified. No existing scale was found to measure all three consent domains, with most only narrowly assessing aspects of any one domain. Information provision was the most frequently assessed domain, followed by comprehension, and then voluntariness. None of the identified scales were found to have adequate evidence for either high quality psychometric properties or patient user acceptability. No existing scale is fit for purpose in comprehensively assessing all domains of informed consent. In the absence of any existing measure meeting the necessary criteria relating to information, comprehension and voluntariness, there is an urgent need for a new measure of medical consent to be developed that is psychometrically sound, spans all three domains and is acceptable to patients and clinicians alike. These findings provide the impetus and justification for the redesign of the informed consent process, with the aim to provide a robust, reliable and replicable process that will in turn improve the quality of the patient experience and care provided.

Informed Consent for Online Research-Is Anybody Reading?: Assessing Comprehension and Individual Differences in Readings of Digital Consent Forms

Informed consent is an important part of the research process; however, some participants either do not read or skim the consent form. When participants do not read or comprehend informed consent, then they may not understand the potential benefits, risks, or details of the study before participating. This study used previous research to develop experimentally manipulated online consent forms utilizing various presentations of the consent form and interactive elements. Participants (n = 576) were randomly exposed to one of six form variations. Results found that the highly interactive condition was significantly better for comprehension than any of the other conditions. The highly interactive condition also performed better for readability, though not significantly. Further research should explore the effects of interactive elements to combat habituation and to engage participants with the parts of the consent form unique to the study.

Strategies for research participant engagement: A synthetic review and conceptual framework

BACKGROUND

Research participant engagement, which we define as recruitment and retention in clinical trials, is a costly and challenging issue in clinical research. Research teams have leveraged a variety of strategies to increase research participant engagement in clinical trials, although a framework and evidence for effective participant engagement strategies are lacking. We (1) developed a novel conceptual framework for strategies used to recruit and retain participants in clinical trials based on their underlying behavioral principles and (2) categorized empirically tested recruitment and retention strategies in this novel framework.

METHODS

We conducted a synthetic analysis of interventions tested in studies from two Cochrane reviews on clinical trial recruitment and retention, which included studies from 1986 to 2015. We developed a conceptual framework of behavioral strategies for increasing research participant engagement using deductive and inductive approaches with the studies included in the Cochrane reviews. Reviewed interventions were then categorized using this framework. We examined the results of reviewed interventions and categorized the effects on clinical trial recruitment and retention as significantly positive, null, or significantly negative; summary statistics are presented for the frequency and effects of each behavioral strategy type.

RESULTS

We analyzed 141 unique interventions across 96 studies: 91 interventions targeted clinical trial research participant recruitment and 50 targeted retention. Our framework included 14 behavioral strategies to improve research participant engagement grouped into four general approaches: changing attitudes by appealing to social motivators, changing attitudes by targeting individual psychology, reducing barriers and cognitive burdens, and providing incentives. The majority of interventions (54%) aimed to reduce barriers or cognitive burdens, with improving comprehension (27%) as the most common specific strategy identified. For recruitment, the most common behavioral strategies tested were building legitimacy or trust (38%) and framing risks and benefits (32%), while financial or material incentives (32%) and reducing financial, time, and social barriers (32%) were most common for retention interventions. Among interventions tested in randomized controlled trials, 51% had a null effect on research participant engagement, and 30% had a statistically significant positive effect.

DISCUSSION

Clinical researchers have tested a wide range of interventions that leverage distinct behavioral strategies to achieve improved research participant recruitment and retention. Common behavioral strategies include building legitimacy or trust between research teams and participants, as well as improving participant comprehension of trial objectives and procedures. The high frequency of null effects among tested interventions suggests challenges in selecting the optimal interventions for increasing research participant engagement, although the proposed behavioral strategy categories can serve as a conceptual framework for developing and testing future interventions.

Implementation of Common Rule Changes to the Informed Consent Form: A Research Staff and Institutional Review Board Collaboration

Background: The Common Rule, which governs federally funded clinical research involving human subjects, formally defines the requirements for institutional review board (IRB) membership, functions and operations, and review of research, as well as the requirements for obtaining informed consent from research participants. The revisions to the Common Rule effective in January 2019 changed some content requirements for informed consent forms.

Methods: This article summarizes the history of informed consent requirements, the changes made to the requirements by the revision to the Common Rule, and the ways in which IRBs and research staff work together to develop informed consent forms that comply with the regulations and provide all the information potential research subjects need to decide whether to participate in a study.

Results: Clinical research coordinators, under their investigators’ supervision, are responsible for ensuring that research consent forms comply with the requirements of the federal regulations and the institution. Many IRBs have provided education regarding these new requirements, as well as consent templates that contain all the required elements. To ensure that the Common Rule's requirements are met, the IRB reviews each study submission, including the consent form. The IRB panel makes revisions to the consent forms as needed and returns the approved consent form to the investigator and clinical research coordinator.

Conclusion: Research coordinators play an essential role in developing consent forms and providing the required review information to the IRB. In turn, through optimizing and standardizing consent forms and ensuring that all requirements of the Common Rule are followed, IRBs ensure that the rights of participants are protected and upheld.

Too Dense and Too Detailed: Evaluation of the Health Literacy Attributes of an Informed Consent Document

The US government recently updated the Common Rule, a set of federal regulations to ensure the ethical conduct of human subjects research. The new regulations require that consent documents provide information that is clear and concise enough to enable truly informed consent. This study explores potential American Indian research participants' understanding and perceptions of an example consent document, focusing on possible improvements to better serve the requirements of the revised Common Rule. Participants completed a survey that collected demographic data and measured health literacy, numeracy, and comprehension of the example document. Next, they participated in focus groups to answer open-ended questions regarding their views on the example document. We calculated mean scores and frequencies of response to analyze quantitative survey data and performed a qualitative thematic analysis of focus group transcripts. Results demonstrated that American Indian participants with relatively strong health literacy skills clearly understood key elements of the consent document, including the purpose of signing it, confidentiality, compensation, and whom to contact for questions. However, they were overwhelmed by details on research procedures and were concerned about the document's layout. To make consent documents more readily comprehensible, participants recommended the addition of headings, bullets, graphics, and relevant pictures. They also recommended a two-step consent process, comprising a short introduction to the research project followed by a longer explanation of procedures. These results illustrate the potential advantages of community engagement in drafting consent materials. Health researchers would likely benefit from community recommendations like the ones we elicited as they design consent documents adherent to the revised Common Rule.

Improved parental understanding by an enhanced informed consent form: a randomized controlled study nested in a paediatric drug trial

OBJECTIVE

This study was designed to evaluate the applicability and effectiveness of the enhanced informed consent form (ICF) methodology, proposed by the Strategic Initiative for Developing Capacity in Ethical Review (SIDCER), in paediatric research requiring parental consent. The objective of this study was to compare the parental understanding of information between the parents who read the SIDCER ICF and those who read the conventional ICF.

DESIGN

A prospective, randomized, controlled design.

SETTING

Paediatric Outpatients Department, Phramongkutklao Hospital, Thailand.

PARTICIPANTS

210 parents of children with thalassemia (age=35.6 ± 13.1 years).

INTERVENTIONS

The parents were randomly assigned to read either the SIDCER ICF (n=105) or the conventional ICF (n=105) of a paediatric drug trial.

PRIMARY AND SECONDARY OUTCOME MEASURES

Parental understanding of trial information was determined using 24 scenario-based questions. The primary endpoint was the proportion of parents who obtained the understanding score of more than 80%, and the secondary endpoint was the total score.

RESULTS

Forty-five parents (42.9%) in the SIDCER ICF group and 29 parents (27.6%) in the conventional ICF group achieved the primary endpoint (relative risk=1.552, 95% CI 1.061 to 2.270, p=0.021). The total score of the parents in the SIDCER ICF group was significantly higher than the conventional ICF group (18.07±3.71 vs 15.98±4.56, p=0.001).

CONCLUSIONS

The SIDCER ICF was found to be superior to the conventional ICF in improving parental understanding of trial information.

How one small text change in a study document can impact recruitment rates and follow-up completions

BACKGROUND

The validity and reliability of longitudinal research is highly dependent on the recruitment and retention of representative samples. Various strategies have been developed and tested for improving recruitment and follow-up rates into health-behavioural research, but few have examined the role of linguistic choices and study document readability on participation rates. This study examined the impact of one small text change, assigning an inappropriate or grade-8 reading level password for intervention access, on participation rates and attrition in an online alcohol intervention trial.

METHODS

Participants were recruited into an online alcohol intervention study using Amazon's Mechanical Turk via a multi-step recruitment process which required participants to log into a study portal using a pre-assigned password. Passwords were qualitatively coded as grade-8 and/or inappropriate for use within a professional setting. Separate logistic regressions examined which demographic, clinical characteristics, and password categorizations were most strongly associated with recruitment rates and follow-up completions.

RESULTS

Inappropriate passwords were a barrier for recruitment among participants with post-secondary education as compared to those with less education (p = 0.044), while grade-8 passwords appeared to significantly facilitate the completion of 6-month follow-ups (p = 0.005).

CONCLUSIONS

Altogether, these findings suggest that some linguistic choices may play an important role in recruitment, while others, such as readability, may have longer-term effects on follow-up rates and attrition. Possible explanations for the findings, as well as, sample selection biases during recruitment and follow-up are discussed. Limitations of the study are stated and recommendations for researchers are provided.

Informational needs for participation in bioequivalence studies: the perspectives of experienced volunteers

PURPOSE

The present study aimed to determine the extent of information that healthy volunteers need in an informed consent form (ICF) to support their decision whether to participate in a bioequivalence study, a type of clinical studies involving the testing of pharmacokinetic equivalence of a generic drug with a brand-name drug in volunteer subjects.

METHODS

This cross-sectional, descriptive study determined the perspectives of individuals who used to participate in bioequivalence studies, using an electronic-based questionnaire. A 5-point modified Likert scale was used to indicate the importance of each element of the ICF content, with an anchored rating scale from 1 (not important) to 5 (very important) for each item.

RESULTS

Of 300 questionnaires distributed, all (100%) were returned. The respondents considered most items to be necessary for their decision, with the score ranging from 3.25 to 4.60 (mean overall score = 4.16 ± 0.30). The four top-rated items were the "major foreseeable risk" (4.60 ± 0.72), "participant's responsibility during participation" (4.52 ± 0.72), "confidentiality and the limit of confidentiality" (4.52 ± 0.82), and "all possible adverse effects of the drug" (4.47 ± 0.74), while the relatively less concerned items were related to general information.

CONCLUSIONS

Most elements of the ICF content required were considered as important by the previously experienced volunteers in bioequivalence studies, notwithstanding that some elements were perceived as more important than others. The data from this study could be used to better tailor relevant information in an ICF to the needs of research participants in bioequivalence studies.

The impact of central IRB's on informed consent readability and trial adherence in SPRINT

Background

Federal agencies have encouraged the use of central institutional review boards (CIRBs) for multi-site clinical trials. There is limited evidence supporting the use of CIRBs. Our aim is to evaluate how SPRINT sites regulated by CIRBs performed regarding informed consent readability and participant trial adherence compared to those regulated by local IRBs.

Methods

We conducted a cohort study using the SPRINT clinical trial. We collected the IRB of record from the stamped and approved 2012 informed consents from each of the sites. We defined CIRB as an IRB for more than one SPRINT site. Our outcomes were informed consent readability measured using the Flesch-Kincaid readability scale and trial adherence defined as a loss to follow-up, consent withdrawal, and missed last 3-month visit.

Results

Sixty-one percent of all SPRINT sites used a CIRB as their IRB of record. The adjusted mean grade reading level for CIRB consents was 13.4 (95% CI 12.6–13.8) compared to 12.3 (95% CI 12.1–13.1) for non CIRB consents (p = 0.07). CIRB sites had similar rates of withdrawal of consent and loss to follow-up as non-CIRB sites; subjects missing the last appointment of the study were more likely to come from sites regulated by a CIRB. The Veterans Affairs CIRB had the lowest rate of withdrawal of consent (1.9%) and the lowest rate of missed appointments (1.9%) among CIRBs.

Conclusions

Niether CIRB-regulated sites nor IRB regulated sites enforce the recommended readability level of the informed consent documents. Sites regulated by both IRBs had similar participant trial adherence.

A comparison of genomic laboratory reports and observations that may enhance their clinical utility for providers and patients

Purpose

To assess clinical chromosomal microarray (CMA) genomic testing reports for the following: (a) usage of reporting elements consistent with 2011 ACMG guidelines and other elements identified in the primary literature, (b) information quality, and (c) readability.

Methods

We retrospectively analyzed genomic testing reports from 2011 to 2016 provided to, or by our laboratory to aid in clinical detection and interpretation of copy number variants. Analysis was restricted to the following sections: interpretation, recommendations, limitations, and citations. Analysis included descriptive characteristics, reporting elements, reading difficulty using the Simple Measure of Gobbledygook (SMOG), and quality ratings using a subset of questions adapted from the DISCERN‐Genetics questionnaire.

Results

The analysis included 44 unique reports from 26 laboratories comprising four groups: specialty laboratories (SL; N = 9), reference laboratories (RL; N = 12), hospital laboratories (HL; N = 10), and university‐based laboratories (UL; N = 13). There were 23 abnormal/pathogenic reports and 21 of uncertain/unknown significance. Nine laboratories did not include one or more pieces of information based on ACMG guidelines; only one of ten laboratories reported condition‐specific management/treatment information when available and relevant. Average quality ratings and readability scores were not significantly different between laboratory types or result classification.

Conclusions

Reporting practices for most report elements varied widely; however, readability and quality did not differ significantly between laboratory types. Management and treatment information, even for well‐known conditions, are rarely included. Effectively communicating test results may be improved if certain reporting elements are incorporated. Recommendations to improve laboratory reports are provided.

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.

Ensuring we involve seldom heard voices in supporting the Data Protection Act 2018 (Section 36(2)) (Health Research) Regulations 2018

This open letter presented by the UCD PPI Ignite executive committee outlines five concerns with regard the Data Protection Act 2018 (Section 36(2)) (Health Research) Regulations 2018. We request that that Department of Health outline a process as to how seldom heard voices will be involved in the Consent Declaration committee and request that national participation information leaflet templates are co-designed. We request for clarity as to how that act relates to the FAIR data principles and how the burden of reconsenting will be reduced. We ask that the act is linked with the Assisted Decision-Making (Capacity) Act 2015 and request the urgent development of codes of practice to support and integrate assisted decision-making into the regulations that should be underpinned with ongoing education to enable a shared understanding.

Improved pregnant women's understanding of research information by an enhanced informed consent form: a randomised controlled study nested in neonatal research

OBJECTIVE

This study aimed to test the applicability and effectiveness of the enhanced informed consent form (ICF) methodology, proposed by the Strategic Initiative for Developing Capacity in Ethical Review (SIDCER), in neonatal research requiring maternal consent.

DESIGN

A single-centre open-label randomised controlled study.

SETTING

Antenatal care clinics at Phramongkutklao Hospital, Thailand.

PATIENTS

234 pregnant women who were at risk of preterm labour were enrolled; 232 individuals completed the study.

INTERVENTIONS

The participants were randomly assigned to read either the SIDCER ICF or the conventional ICF.

MAIN OUTCOME MEASURES

The participants' understanding of essential trial-related information was assessed using 25 closed-ended questions. The primary endpoint was the proportion of the participants who obtained the satisfactory level of understanding at 80% (score of ≥20/25).

RESULTS

72.5% (87/120) of the participants in the SIDCER ICF group and 59.8% (67/112) of the conventional ICF group achieved the primary endpoint (relative risk (RR)=1.212, 95% CI 1.005 to 1.462, p=0.041). The superiority of the SIDCER ICF over the conventional ICF was significant, particularly among the participants whose education was at the high school level or below (63.5% vs 44.1%, RR=1.441, 95% CI 1.022 to 2.030, p=0.031).

CONCLUSIONS

The SIDCER ICF methodology is applicable to neonatal research requiring maternal consent. The SIDCER ICF significantly improved the understanding of pregnant women, particularly among those with lower levels of education. The present study confirms the value of the SIDCER ICF methodology in research involving individuals with a limited academic background.

Assessing usefulness and researcher satisfaction with consent form templates

Introduction

We aimed to improve the research consenting process by developing and evaluating simplified consent forms.

Methods

Four templates written at the eighth-tenth grade reading level were developed and trialed by a group of experts in clinical research, health literacy, national regulatory requirements, and end users. Researchers from protocols which had received expedited review were surveyed at 2 time points regarding their use and assessment of the templates.

Results

At baseline 18/86 (20.9%) responding researchers had heard of the templates and 5 (5.8%) reported that they had used them; 2 years later, 54.2% (32/59) had heard of the templates and 87.5% (28/32) had used them (p<0.001).

Conclusions

Consent form templates may be one mechanism to improve patient comprehension of research protocols as well as efficiency of the review process, but require considerable time for development and implementation, and one key to their success is involvement and support from the IRB and technical staff.

The Appropriateness of Language Found in Research Consent Form Templates: A Computational Linguistic Analysis

Background

To facilitate informed consent, consent forms should use language below the grade eight level. Research Ethics Boards (REBs) provide consent form templates to facilitate this goal. Templates with inappropriate language could promote consent forms that participants find difficult to understand. However, a linguistic analysis of templates is lacking.

Methods

We reviewed the websites of 124 REBs for their templates. These included English language medical school REBs in Australia/New Zealand (n = 23), Canada (n = 14), South Africa (n = 8), the United Kingdom (n = 34), and a geographically-stratified sample from the United States (n = 45). Template language was analyzed using Coh-Metrix linguistic software (v.3.0, Memphis, USA). We evaluated the proportion of REBs with five key linguistic outcomes at or below grade eight. Additionally, we compared quantitative readability to the REBs’ own readability standards. To determine if the template’s country of origin or the presence of a local REB readability standard influenced the linguistic variables, we used a MANOVA model.

Results

Of the REBs who provided templates, 0/94 (0%, 95% CI = 0–3.9%) provided templates with all linguistic variables at or below the grade eight level. Relaxing the standard to a grade 12 level did not increase this proportion. Further, only 2/22 (9.1%, 95% CI = 2.5–27.8) REBs met their own readability standard. The country of origin (DF = 20, 177.5, F = 1.97, p = 0.01), but not the presence of an REB-specific standard (DF = 5, 84, F = 0.73, p = 0.60), influenced the linguistic variables.

Conclusions

Inappropriate language in templates is an international problem. Templates use words that are long, abstract, and unfamiliar. This could undermine the validity of participant informed consent. REBs should set a policy of screening templates with linguistic software.

Readability and Content Assessment of Informed Consent Forms for Phase II-IV Clinical Trials in China

Purpose

To explore the readability and content integrity of informed consent forms (ICFs) used in China and to compare the quality of Chinese local ICFs with that of international ICFs.

Methods

The length, readability and content of 155 consent documents from phase II-IV drug clinical trials from the Third Xiangya Hospital Ethics Committee from November 2009 to January 2015 were evaluated. Reading difficulty was tested using a readability formula adapted for the Chinese language. An ICF checklist containing 27 required elements was successfully constructed to evaluate content integrity. The description of alternatives to participation was assessed. The quality of ICFs from different sponsorships were also compared.

Results

Among the 155 evaluable trials, the ICFs had a median length of 5286 words, corresponding to 7 pages. The median readability score was 4.31 (4.02–4.41), with 63.9% at the 2^nd level and 36.1% at the 3^rd level. Five of the 27 elements were frequently neglected. The average score for the description of alternatives to participation was 1.06, and 27.7% of the ICFs did not mention any alternatives. Compared with Chinese local ICFs, international ICFs were longer, more readable and contained more of the required elements (P < 0.05).

Conclusion

The ICFs used in China were difficult to read for most participants. These forms had poor description of alternatives to participation, and failed to provide a high degree of information disclosure, including an explanation of informed consent, follow-up processing of the data/sample, inclusion/exclusion criteria, double blinding, and unpredictable risks. International ICFs had better readability and content integrity than Chinese local ICFs. More efforts should thus be made to improve the quality of consent documents in China.
