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.

Shared decision-making and specific informed consent in patients with aortic aneurysms

OBJECTIVE

To analyze the refusal rate of elective aortic aneurysm surgery in asymptomatic patients after the presentation of a detailed informed consent form followed by a meeting where patient and their families can analyze each item.

METHODS

We conducted a retrospective analysis of 49 patients who had aneurysms and were offered surgical treatment between June 2017 and February 2019. The patients were divided into two groups: the Rejected Surgery Group, which was composed of patients who refused the proposed surgical treatment, and the Accepted Surgery Group, comprising patients who accepted the proposed surgeries and subsequently underwent them.

RESULTS

Of the 49 patients, 13 (26.5%) refused surgery after reading the informed consent and attending the comprehensive meeting. We observed that patients who refused surgery had statistically smaller aneurysms than those who accepted surgery (9% versus 26%). These smaller aneurysms were above the indication size, according to the literature.

CONCLUSION

One-quarter of patients who were indicated for elective surgical repair of aortic aneurysms rejected surgery after shared decision-making, which involved presenting patients with an informed consent form followed by a clarification meeting for them and their families to analyze each item. The only factor that significantly influenced a rejection of the procedure was the size of the aneurysm; patients who rejected surgery had smaller aneurysms than those who accepted surgery. Up to 26% of patients with aortic aneurysms refused surgical repair. The proposed technique, whether open or endovascular, did not influence patients' decisions. Patients with smaller aneurysms were more likely to refuse aortic aneurysm treatment.

A cross-sectional audit of informed consent of online survey: Characteristics and adherence to prevalent guidelines

Background

Research on human participants requires formal approval from a competent ethics committee. During the recruitment of the research participants, obtaining informed consent is a prerequisite. The online survey method is used by many researchers as it can collect the data from a diverse population in a short time.

Aim

This study aimed to observe the characteristics and adherence to prevalent guidelines (set by the Indian Council of Medical Research [ICMR]) of informed consent coupled with online surveys.

Methods

We collected the informed consent text from online survey links obtained from a network of colleagues who got a request to participate in a survey. Data were collected from July 2020 to June 2022. The text was anonymized for further analysis. The word count, sentences, and Flesch reading ease score were calculated. The adherence to ICMR guidelines where checked by two authors individually and a consensus was reached to prepare the final result.

Results

A total of 44 online surveys in English were audited and among them, 10 did not have informed consent. The informed consent in 34 surveys had a median of 6 sentences and 84 words. The median reading ease score was 45.7 (college level). The majority of the consent states the purpose of the research (91.18%), the voluntary nature of the participation (85.29%), and mentioned that it is research (64.71%). However, the rest of the components are ignored by the majority of the survey consent form.

Conclusion

Informed consent form with online surveys lacks adherence to the components suggested by ICMR. Hence, the forms should be made carefully by the researchers so that the vigor of informed consent is maintained in the online surveys.

Determination of the Readability Level of Consent Forms Used in the Gynecology and Obstetrics Clinic at Suleyman Demirel University

Background This study aimed to evaluate the readability level of consent forms used for interventional procedures in the obstetrics and gynecology clinic and to determine the readability of the texts according to the education level of the patient. Methodology This study determined the readability of patient consent forms used before interventional procedures in the gynecology and obstetrics clinic at the Suleyman Demirel University Hospital, Isparta. The consent forms were divided into two main groups according to their use in obstetrics and gynecology procedures. The readability level of consent forms was assessed using two readability formulas developed by Ateşman and Bezirci-Yılmaz, which determine the readability level of Turkish texts in the literature. Results When the consent forms were analyzed according to Atesman's readability formula, they were found to be readable with more than 15 years of education at the undergraduate level, while according to Bezirci-Yılmaz's readability formula, they were found to be readable with 17 years of education at the postgraduate level. Conclusions Easy-to-read consent forms will ensure that patients are more informed about interventional procedures and participate more effectively in the treatment process. There is a need to develop readable consent forms suitable for the general education level.

Willingness of intensive care unit patients' family members to donate organs: A cross-sectional study

The large gap between the demand for, and the supply of organs worldwide makes promoting organ donation an important global social issue. Even after someone has signed a consent form or registered for organ donation, ethically, the hospital still requires a family member's written permission before organ donation can proceed. As a result, a family member rather than the patient makes the final decision. This study investigated the willingness of the family members of hypothetical patients in intensive care units (ICUs) suffering from an irreversible condition to sign an organ donation consent form. A cross-sectional survey was conducted among family members of ICU patients recruited from one medical center in southern Taiwan from April to October 2014, which followed the STROBE guidelines. Of 110 ICU family members, 71 (64.5%) were willing to donate the organs of hypothetical patients with irreversible conditions. Based on logistic regression, family support, attitude, and knowledge of organ donation significantly predicted 34% of the variance in willingness to sign consent. Attitude toward organ donation and behavioral knowledge of organ donation correlated significantly with a willingness to sign a consent form. This study found that family support and organ donation attitudes were important factors in predicting the willingness to sign a consent form for the organ donation of hypothetical patients. The study provides evidence that nurses and healthcare staff need to consider family support and educate families on organ donation to encourage potential donors to accept and agree to organ donation.

Formal Quality and Compliance of Informed Consent Forms in Critical Care and Surgical Areas in Spain: An Observational Study

(1) Background: The informed consent form must contain all the relevant information about the procedure to be performed to guarantee the patient's freedom to choose. (2) Objective: To analyze the formal quality of, and compliance with informed consent forms in critical care and surgical areas in a county hospital in Spain. (3) Methods: The formal quality of informed consent forms in critical care and surgical areas from the hospital were analyzed, following the established formal quality criteria for informed consent forms. The compliance with specific criteria for each of the operated patients during the period of study was also evaluated. (4) Results: The formal quality of 224 informed consent forms was analyzed from 8 disciplines observing a median of non-compliances of 4 with a minimum of 1 and a maximum of 5, with the most breaches being in verifying the delivery of a copy to the patient and showing contraindications. The compliance of 376 documents from 188 operated patients were assessed, highlighting that the non-complied items were: the personalized risks and complete identification of the patient and the physician. A significant association was found between disciplines analyzed and the identification of the physician and personalized risks, with anesthesia and critical care showing the best compliance. (4) Conclusions: The informed consent forms in critical care and surgical areas were shown to have a deficient formal quality and an inadequate compliance. These deficiencies should be corrected to improve the information received by the patients and to guarantee their freedom to choose. As nurses have a responsibility to ensure that patients are adequately informed about both nursing interventions and care, as well as the surgical treatments they receive, consideration should be given to the possibility of nursing professionals taking the lead in obtaining informed consent.

The importance of applying the statement of assent to children and adolescents: a qualitative study

OBJECTIVES

To describe the importance of the Statement of Assent for children and adolescents invited to participate in a clinical study and their main reactions to its explanation.

METHODS

This is an exploratory descriptive qualitative study of 17 children and adolescents, who were invited to participate in a clinical study in the field of oncology in a hospital located in Rio de Janeiro (Brazil). Data were analyzed using thematic analysis.

RESULTS

Two thematic units were generated after data interpretation: signing the statement of assent, in which participants felt their main role when faced with the possibility of expressing their agreement or not to take part in the study; and understanding of the study, when they showed that they understood the steps of the study by asking pertinent questions to clarify their doubts. Children and adolescents understood the steps of the study contained in the Statement of Assent, were interested and asked questions to clarify their doubts about the study.

CONCLUSIONS

The Statement of Assent was important for participants understanding the study and having autonomy over their participation. As the statement strengthened the main role of children and adolescents in the research process, the conclusion was that its use in studies involving the pediatric population should be encouraged.

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.

Lessons Learned for Identifying and Annotating Permissions in Clinical Consent Forms

BACKGROUND

The lack of machine-interpretable representations of consent permissions precludes development of tools that act upon permissions across information ecosystems, at scale.

OBJECTIVES

To report the process, results, and lessons learned while annotating permissions in clinical consent forms.

METHODS

We conducted a retrospective analysis of clinical consent forms. We developed an annotation scheme following the MAMA (Model-Annotate-Model-Annotate) cycle and evaluated interannotator agreement (IAA) using observed agreement (A o), weighted kappa (κw ), and Krippendorff's α.

RESULTS

The final dataset included 6,399 sentences from 134 clinical consent forms. Complete agreement was achieved for 5,871 sentences, including 211 positively identified and 5,660 negatively identified as permission-sentences across all three annotators (A o = 0.944, Krippendorff's α = 0.599). These values reflect moderate to substantial IAA. Although permission-sentences contain a set of common words and structure, disagreements between annotators are largely explained by lexical variability and ambiguity in sentence meaning.

CONCLUSION

Our findings point to the complexity of identifying permission-sentences within the clinical consent forms. We present our results in light of lessons learned, which may serve as a launching point for developing tools for automated permission extraction.

Redesign of an informed consent form to increase participation in a school-based dental program

OBJECTIVES

The study aimed to determine if modifications to the design of a consent form and consenting process increased participation rates in the Indiana University School of Dentistry's Mobile School-Based Dental Program (Seal Indiana).

METHODS

Kaizen methodology was followed to identify problem areas in the consenting process. Additionally, stakeholders were invited to participate in focus groups and fill out surveys to identify issues preventing participation in the Seal Indiana program (N = 48) and later to evaluate the changes made (N = 48). The redesigned form and process were then used in a pilot study at 14 sites to determine the impact that changes had on levels of participation as measured by the number of consent forms completed and returned.

RESULTS

There was a statistically significant increase in the number of consent forms returned. The measured change represented a 32 percent increase in program participation (P value = 0.035). A statistically significant increase was observed in how participants viewed the attractiveness of the form and how easy it was to read and comprehend.

CONCLUSIONS

In order to increase consenting rates, our results indicate modifications to the consent form should be focused on the following characteristics: esthetics, ease of reading and comprehending information, and making the Health Insurance Portability and Accountability Act of 1996 (HIPPA) privacy regulations easier to read and comprehend.

"Let's Get the Consent Together": Rethinking How Surgeons Become Competent to Discuss Informed Consent

OBJECTIVE

Eliciting informed consent is a clinical skill that many residents are tasked to conduct without sufficient training and before they are competent to do so. Even senior residents and often attending physicians fall short of following best practices when conducting consent conversations.

DESIGN

This is a perspective on strategies to improve how residents learn to collect informed consent based on current literature.

CONCLUSIONS

We advocate that surgical educators approach teaching informed consent with a similar framework as is used for other surgical skills. Informed consent should be defined as a core clinical skill for which attendings themselves should be sufficiently competent and residents should be assessed through direct observation prior to entrustment.

Clinical management, ethics and informed consent related to multi-gene panel-based high throughput sequencing testing for platelet disorders: Communication from the SSC of the ISTH

Molecular diagnostics of inherited platelet disorders (IPD) has been revolutionized by the implementation of high-throughput sequencing (HTS) approaches. A conclusive diagnosis using HTS tests can be obtained quickly and cost-effectively in many, but not all patients. The expanding use of HTS tests has raised concerns regarding complex variant interpretation and the ethical implications of detecting unsolicited findings such as variants in IPD genes RUNX1, ETV6, and ANKRD26, which are associated with increased leukemic risk. This guidance document has been developed and written by a multidisciplinary team of researchers and clinicians, with expertise in hematology, clinical and molecular genetics, and bioethics, alongside a RUNX1 patient advocacy representative. We recommend that for clinical diagnostics, HTS for IPD should use a multigene panel of curated diagnostic-grade genes. Critically, we advise that an HTS test for clinical diagnostics should only be ordered by a clinical expert that is: (a) fully aware of the complexity of genotype-phenotype correlations for IPD; (b) able to discuss these complexities with a patient and family members before the test is initiated; and (c) able to interpret and appropriately communicate the results of a HTS diagnostic report, including the implication of variants of uncertain clinical significance. Each patient should know what an HTS test could mean for his or her clinical management before initiating a test. We hereby propose an exemplified informed consent document that includes information on these ethical concerns and can be used by the community for implementation of HTS of IPD in a clinical diagnostic setting. This paper does not include recommendations for HTS of IPD in a research setting.

Role of the consent form in UK veterinary practice

Background

Informed consent from the client is required before veterinary professionals may administer treatment or perform surgery on an animal patient, except in an emergency. This study investigates the potential role(s) of the consent form in the consent process in the UK.

Methods

Thematic analysis was carried out on the text contained in 39 blank consent forms sourced from veterinary practices in the UK. Analysis was conducted at the levels of topical survey and thematic summary.

Results

Consent forms were used to authorise procedures, to define proposed treatment, to offer or recommend additional procedures, to convey the risks of treatment and to document the client’s financial obligations. None of the forms analysed provided sufficient space to document the accompanying conversation. Notable omissions from the submitted forms included options for treatment and benefits of treatment.

Conclusions

The consent form acts as a record of the procedure to be performed, the associated costs and the status of the person giving consent. However, from this analysis, it often fails to record the detail of the consent discussion, an essential part of the consent process. A proposal for an improved version of a veterinary consent form is provided.

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.

Improving Translation and Cultural Appropriateness of Spanish-Language Consent Materials for Biobanks

A growing proportion of prospective research participants in the United States speak limited or no English. We conducted cognitive interviews with native Spanish speakers to test Spanish-language translations of simplified and traditional biobank consent forms. Comprehension was generally high and did not differ by form. Most of those who received the simplified form felt it contained the right amount of information, compared with fewer than half of those who received the traditional form. Qualitative results allowed us to identify overarching issues related to tone, formality, and voice that may affect prospective participants' trust and willingness to participate. Certain characteristics of written Spanish are seemingly at odds with recommended actions to simplify consent forms; thus, even when significant empirical effort has been expended to develop simplified consent materials in English, additional work is needed to ensure the accuracy, comprehensibility, and cultural-congruence of Spanish-language translations.

Informed Consent Education in Obstetrics and Gynecology: A Survey Study

OBJECTIVE

The practice of obstetrics and gynecology poses specific ethical challenges for informed consent (IC). Data regarding resident confidence with the IC process are lacking. Our objective was to evaluate obstetrics and gynecology residents' education, experience, and confidence related to IC.

DESIGN

This was a cross-sectional survey of obstetrics and gynecology residents. Descriptive analyses were performed using mean and standard deviation or frequency expressed as a percentage. The results were analyzed for statistical significance using chi-square or Fisher's exact tests for categorical variables and Student t or Mann-Whitney U tests, as appropriate, for continuous variables; all results yielding p < 0.05 were deemed statistically significant.

SETTING

Electronic survey.

RESULTS

Two hundred eighty-one trainees completed the survey. The majority of participants were female (84.3%) and from an academic training program (65.1%). Two hundred seventy-seven trainees (98.6%) reported that they had obtained IC for operating room procedures; the majority had first done this in the first postgraduate year (PGY) (n = 258, 91.8%). Trainees most commonly obtain IC for resident and general gynecology attending cases. Most trainees primarily learn how to obtain IC via observation of their coresidents and attendings. Nearly 90% of trainees have obtained IC for a procedure for which they were unsure of all the risks. One hundred seventy-three trainees (61.6%) reported that they would like to have more training in IC. Increasing PGY was significantly associated with increasing confidence in obtaining IC for gynecologic, obstetric, and office procedures (all p < 0.01). There were no differences based on PGY in frequency of reviewing who will perform the surgical procedure (p = 0.75), how trainees will be involved in the procedure (p = 0.35), review of alternative treatments (p = 0.91), or in documentation of the IC process (p = 0.16).

CONCLUSIONS

Based on the findings of this survey study, education related to the IC process is warranted and curriculum development should be the focus of future study.

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.

An Analysis of Informed Consent Form Readability of Oncology Research Protocols

Twenty-two percent of adults in the United States have only basic health literacy skills. We used a multiple linear regression model to identify associations between readability of informed consent documents with study sponsor, study phase, and approval year using a sample of 143 oncology studies at Ochsner Medical Center. The M ± SD Flesh-Kincaid Reading Grade Level (RGL) was 10.33 ± 0.85 and Flesh Reading Ease (FRE) was 52.89 ± 5.49. National Cancer Institute studies had a significantly lower mean RGL and FRE as compared with other sponsors (RGL 9.85 ± 0.66 vs. 10.72 ± 0.79; p value < .0001). Mean RGL did not differ by study phase. Future research should include assessment and improvement of the readability of informed consent documents.

Assessment of Motivations and Willingness to Participate in Research of Outpatients With Anxiety, Mood, and Psychotic Disorders

The motivations of participants recruited for research, especially from potentially vulnerable populations, have received increasing attention. The present investigation compares the motivations and willingness to participate in research of 134 psychiatric outpatients and 50 controls. The willingness to participate of both groups was similar. We found a higher proportion of psychiatric admissions and a higher degree of computer literacy among those willing to participate. Regardless of their decision concerning participation, the reasons given by the members of both groups were logical and concordant with the related literature. This suggests that negative views about the motivations of psychiatric patients to act as research participants are unfounded. Efforts should focus on the predictors of willingness to participate that we have identified for improving recruitment. The implications of these results for research are discussed.

Randomized Quality Improvement Trial of Opting-In Versus Opting-Out to Increase Influenza Vaccination Rates during Pregnancy

Introduction  Despite strong recommendations, only 40.6% of pregnant women attending two prenatal clinics were vaccinated against influenza during the 2009 pandemic. We tested whether an opting-out approach would improve vaccine uptake. Methods  We conducted a randomized quality improvement (QI) trial to compare opting-out with conventional opting-in consent for influenza immunization. Women age ≥ 18 years attending the University of Texas Health Science Center at Houston (UTHealth) or UT-Medical Branch (UTMB) prenatal clinics during the 2010-2011 influenza season, were eligible. Results  We enrolled 280 women (140 UTHealth, 140 UTMB). Both groups had similar mean age (26.0 ± 5.5 years), mean gestational age (19.4 ± 9.5 weeks), and percent with underlying health conditions (20.7%). Vaccination rates with opting-in and opting-out were similar among all (83 vs. 84%), UTHealth (87 vs. 93%), and UTMB patients (79 vs.76%) ( p  > 0.05). In subsamples of patients assessed, consent strategy did not significantly affect maternal recall of information provided. Conclusion  While prenatal influenza vaccination uptake doubled from the 2009-2010 influenza season, opting-out did not perform better than opting-in, a conclusion opposite that we would have reached had this been a nonconcurrent trial. Vaccination rates dropped posttrial; hence, continued research is needed to increase the prenatal influenza immunizations.

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.

Evidence-Based Strategies for Shortening Informed Consent Forms in Clinical Research

Long informed consent forms (ICFs) remain commonplace, yet they can negatively affect potential participants' understanding of clinical research. We aimed to build consensus among six groups of key stakeholders on advancing the use of shorter ICFs in clinical research. Partnering with the HIV Prevention Trials Network (HPTN), we used a modified Delphi process with semistructured interviews and online surveys. Concerns about redundancy of information were common. Respondents supported three strategies for reducing ICF length: (a) 91% agreed or strongly agreed with grouping study procedures by frequency, (b) 91% were comfortable or very comfortable with placing supplemental information into appendices, and (c) 93% agreed or strongly agreed with listing duplicate side effects only once. Implementing these strategies will facilitate adoption of the proposed changes to U.S. regulations on ICF length, should they be enacted.

Social Annotation Valence: The Impact on Online Informed Consent Beliefs and Behavior

Background

Social media, mobile and wearable technology, and connected devices have significantly expanded the opportunities for conducting biomedical research online. Electronic consent to collecting such data, however, poses new challenges when contrasted to traditional consent processes. It reduces the participant-researcher dialogue but provides an opportunity for the consent deliberation process to move from solitary to social settings. In this research, we propose that social annotations, embedded in the consent form, can help prospective participants deliberate on the research and the organization behind it in ways that traditional consent forms cannot. Furthermore, we examine the role of the comments’ valence on prospective participants’ beliefs and behavior.

Objective

This study focuses specifically on the influence of annotations’ valence on participants’ perceptions and behaviors surrounding online consent for biomedical research. We hope to shed light on how social annotation can be incorporated into digitally mediated consent forms responsibly and effectively.

Methods

In this controlled between-subjects experiment, participants were presented with an online consent form for a personal genomics study that contained social annotations embedded in its margins. Individuals were randomly assigned to view the consent form with positive-, negative-, or mixed-valence comments beside the text of the consent form. We compared participants’ perceptions of being informed and having understood the material, their trust in the organization seeking the consent, and their actual consent across conditions.

Results

We find that comment valence has a marginally significant main effect on participants’ perception of being informed (F₂=2.40, P=.07); specifically, participants in the positive condition (mean 4.17, SD 0.94) felt less informed than those in the mixed condition (mean 4.50, SD 0.69, P=.09). Comment valence also had a marginal main effect on the extent to which participants reported trusting the organization (F₂=2.566, P=.08). Participants in the negative condition (mean 3.59, SD 1.14) were marginally less trusting than participants exposed to the positive condition (mean 4.02, SD 0.90, P=.06). Finally, we found that consent rate did not differ across comment valence conditions; however, participants who spent less time studying the consent form were more likely to consent when they were exposed to positive-valence comments.

Conclusions

This work explores the effects of adding a computer-mediated social dimension, which inherently contains human emotions and opinions, to the consent deliberation process. We proposed that augmenting the consent deliberation process to incorporate multiple voices can enable individuals to capitalize on the knowledge of others, which brings to light questions, problems, and concerns they may not have considered on their own. We found that consent forms containing positive valence annotations are likely to lead participants to feel less informed and simultaneously more trusting of the organization seeking consent. In certain cases where participants spent little time considering the content of the consent form, participants exposed to positive valence annotations were even more likely to consent to the study. We suggest that these findings represent important considerations for the design of future electronic informed consent mechanisms.

Informed Consent-Uninformed Participants: Shortcomings of Online Social Science Consent Forms and Recommendations for Improvement

As informed consent forms continue to lengthen, are these lengthening forms helping to create better informed participants? The aim of this research was to determine whether the length of consent forms affected reading frequency and comprehension, and to provide recommendations on how to improve consent forms in the social sciences so they are more likely to be read. A quasi-experiment was conducted using actual consent forms at two liberal arts schools, one requiring a long form (463 words, n = 73) and one requiring a shorter form (236 words, n = 57). Participants exposed to the shorter form reported fully reading, or at least skimming the form more frequently than those exposed to the longer form. Those exposed to the shorter form also comprehended more of the form's information. The majority of participants indicated consent forms need to be shortened if researchers want future participants to be more likely to read these forms' contents. Additional recommendations are discussed.

A Review of Consent Documents From Canadian IVF Clinics, 1991 to 2014

OBJECTIVE

We reviewed the content of IVF consent documents (i.e., consent forms and accompanying information sheets) used by Canadian IVF clinics in 1991, 2004, and 2014, paying particular attention to the inclusion of information that should be provided to patients in accordance with minimum ethical standards for disclosure.

METHODS

We contacted all Canadian IVF clinics in operation in 1991 (17 clinics), 2004 (24 clinics), and 2014 (35 clinics) by mail and requested blank copies of their IVF consent documents. Documents received were reviewed for the inclusion of information about the nature of IVF, the potential benefits of IVF, the potential harms and inconveniences of IVF, confidentiality, voluntariness, and options for the use or discarding of embryos not transferred in the original stimulated cycle (sometimes referred to as supernumerary, excess, or spare embryos).

RESULTS

We received responses from 11 of 17 clinics operating in 1991 (response rate 65%), 14 of 24 clinics operating in 2004 (response rate 58%), and 11 of 35 clinics operating in 2014 (response rate 31%). In general, comparisons of the 1991, 2004, and 2014 data sets showed a long-term decrease in documented disclosure of information that should be provided to patients in accordance with minimum ethical standards. The only cases in which this trend appeared to be reversed was with disclosure about the probability of supernumerary embryos, long-term risks of treatment, the right to revoke consent to the use or discarding of supernumerary embryos, and some of the options for the use of supernumerary embryos. In these few instances, there was a notable improvement in the disclosure of relevant information between 1991 and 2014.

CONCLUSION

The disclosure of information relevant to the interests of those undergoing IVF and those who are born as a result of IVF appears to be decreasing. Furthermore, the information that increasingly is being disclosed in consent documents appears to be directing the orientation and content of these documents away from the primary interests of the relevant women, couples, and children. These two trends are inconsistent with the goal of informed consent.

Informed consent and Italian physicians: change course or abandon ship--from formal authorization to a culture of sharing

In Italy in recent years, an exponential increase in the frequency of medical malpractice claims relating to the issue of informed consent has substantially altered not only medical ethics, but medical practice as well. Total or partial lack of consent has become the cornerstone of many malpractice lawsuits, and continues to be one of the primary cudgels against defendant physicians in Italian courtrooms. Physicians have responded to the rising number of claims with an increase in 'defensive medicine' and a prevailing preoccupation with the purely formal aspects of consent. The result is a plethora of consent forms, believed to be a guarantee of 'informed consent', as well as a growing reliance on informed consent as a shield against judicial action brought by the patient. Physicians 'inform' patients without really sharing information, often delegating the task of communication to other professionals who are not doctors. Italian judges always condemn the physician when information to the patient has been inadequate, thus leading insurance companies to consider the lack of valid informed consent as the total responsibility of the physician and/or the hospital. It is necessary to change tack, to remove this idea of consent which permeates the defensive culture of medical practice. Italian physicians need to be trained, first of all, to become aware that information and consent are two distinct processes, albeit closely connected. Valid communication (in which there is information and consent) demands a higher level of professionalism from physicians.

Obtaining subjects' consent to publish identifying personal information: current practices and identifying potential issues

BACKGROUND

In studies publishing identifying personal information, obtaining consent is regarded as necessary, as it is impossible to ensure complete anonymity. However, current journal practices around specific points to consider when obtaining consent, the contents of consent forms and how consent forms are managed have not yet been fully examined. This study was conducted to identify potential issues surrounding consent to publish identifying personal information.

METHODS

Content analysis was carried out on instructions for authors and consent forms developed by academic journals in four fields (as classified by Journal Citation Reports): medicine general and internal, genetics and heredity, pediatrics, and psychiatry. An online questionnaire survey of editors working for journals that require the submission of consent forms was also conducted.

RESULTS

Instructions for authors were reviewed for 491 academic journals (132 for medicine general and internal, 147 for genetics and heredity, 100 for pediatrics, and 112 for psychiatry). Approximately 40% (203: 74 for medicine general and internal, 31 for genetics and heredity, 58 for pediatrics, and 40 for psychiatry) stated that subject consent was necessary. The submission of consent forms was required by 30% (154) of the journals studied, and 10% (50) provided their own consent forms for authors to use. Two journals mentioned that the possible effects of publication on subjects should be considered. Many journal consent forms mentioned the difficulties in ensuring complete anonymity of subjects, but few addressed the study objective, the subjects' right to refuse consent and the withdrawal of consent. The main reason for requiring the submission of consent forms was to confirm that consent had been obtained.

CONCLUSION

Approximately 40% of journals required subject consent to be obtained. However, differences were observed depending on the fields. Specific considerations were not always documented. There is a need to address issues around the study objective, subjects' right to refuse consent and the withdrawal of consent. Whether responsibility for ensuring that the consent form has been signed lies with publishers also needs to be discussed.

Recruitment and follow-up of adolescent and young adult cancer survivors: the AYA HOPE Study

INTRODUCTION

Cancer is rare in adolescents and young adults (AYA), but these patients have seen little improvement in survival in contrast to most other age groups. Furthermore, participation in research by AYAs is typically low. We conducted a study to examine the feasibility of recruiting a population-based sample of AYA survivors to examine issues of treatment and health outcomes.

METHODS

Individuals diagnosed in 2007-08 and age 15-39 at the time of diagnosis with acute lymphocytic leukemia, Hodgkin lymphoma, non-Hodgkin lymphoma, germ cell cancer or sarcoma were identified by 7 Surveillance, Epidemiology, and End-Results (SEER) cancer registries, mailed surveys within 14 months after diagnosis and again a year later, and had medical records reviewed.

RESULTS

525 (43%) of the eligible patients responded, 39% refused and 17% were lost to follow-up. Extensive efforts were required for most potential respondents (87%). 76% of respondents completed the paper rather than online survey version. In a multivariate model, age, cancer site, education and months from diagnosis to the first mailing of the survey were not associated with participation, although males (p  <  0.01), Hispanics and non-Hispanic blacks (p  <  0.001) were less likely to participate. 91% of survivors completing the initial survey completed the subsequent survey.

DISCUSSION

Despite the response rate, those who participated adequately reflected the population of AYA cancer survivors. The study demonstrates that cancer registries are valuable foundations for conducting observational, longitudinal population-based research on AYA cancer survivors.

IMPLICATIONS FOR CANCER SURVIVORS

Achieving a reasonable response rate in this population is possible, but requires extensive resources.

Subjects agree to participate in environmental health studies without fully comprehending the associated risk

Recent advances in environmental health research have greatly improved our ability to measure and quantify how individuals are exposed. These advances, however, bring bioethical uncertainties and potential risks that individuals should be aware of before consenting to participate. This study assessed how well participants from two environmental health studies comprehended consent form material. After signing the consent form, participants were asked to complete a comprehension assessment tool. The tool measured whether participants could recognize or recall six elements of the consent form they had just reviewed. Additional data were collected to look for differences in comprehension by gender, age, race, and the time spent reading the original consent form. Seventy-three participants completed a comprehension assessment tool. Scores ranged from 1.91 to 6.00 (mean = 4.66); only three people had perfect comprehension scores. Among the least comprehended material were questions on study-related risks. Overall, 53% of participants were not aware of two or more study-related risks. As environmental public health studies pose uncertainties and potential risks, researchers need to do more to assess participants’ understanding before assuming that individuals have given their ‘informed’ consent.
