Germline Genome Editing Research: What Are Gamete Donors (Not) Informed About in Consent Forms?
Emilia Niemiec, Heidi Carmen Howard
The CRISPR Journal, February 2020; 3(1) 2020
The potential for using germline genome editing (GGE) in humans has garnered a lot of attention, both for its scientific possibilities as well as for the ethical, legal, and social challenges it ignites. The ethical debate has focused primarily on the suggestions of using GGE to establish a pregnancy (i.e., to offer it in a clinical setting), which is, to date, illegal in many jurisdictions. The use of GGE in research (where a pregnancy would not be established) has received much less attention, despite the fact that it raises serious ethical and social issues as well. Herein, we report on the analysis of informed consent forms for egg and sperm donation used in a widely publicized study where genome editing was used to correct a disease-causing genetic mutation in human embryos. Importantly, embryos were created using eggs and sperm obtained specifically for these experiments. The analysis indicates deficiencies in how the forms addressed various issues, including limited and potentially misleading information about the sensitive nature of the study, the lack of an explicit mention of genomic sequencing, as well as the poor readability of the forms. Furthermore, the arguably high compensation of U.S.$5,000 for egg donors raises questions about undue inducement to participate in research. Moreover, since the procurement of eggs involves serious health risks, it may be questioned whether research requiring such a procedure should be pursued. If such experiments are continued, donors should be informed about all relevant aspects in order to make informed decisions about participating.
Informed Consent for Genetic Testing in Autopsy
Archives of Pathology & Laboratory Medicine, 2020
As next generation sequencing, whole exome sequencing, and other genetic tests become cheaper and more prevalent, pathologists will likely incorporate genetic testing into routine autopsies. Such testing has great promise for helping diagnose and treat living and future family members, but also raises questions about whether current consenting practices for autopsy are adequate. How is informed consent in the autopsy context different from informed consent in the typical clinical setting? Should we require specific consent for genetic autopsy testing?…

Journal of Medical Ethics, 20 February 2020
This study aimed to describe how parents and physicians experienced the informed consent interview and to investigate the aspects of the relationship that influenced parents’ decision during the consent process for a randomised clinical trial in a tertiary neonatal intensive care unit (NICU). The secondary objective was to describe the perspectives of parents and physicians in the specific situation of prenatal informed consent.
Single centre study in NICU of the Centre Hospitalier Intercommunal de Créteil, France, using a convenience period from February to May 2016.
Ancillary study to a randomised clinical trial: Prettineo. Records of interviews for consent. Population: parents and physicians. Mixed study including qualitative and quantitative interview data about participants’ recall and feelings about the consent process. Interviews were reviewed using thematic discourse analysis.
Parents’ recall and understanding of the study’s main goal and design was good. Parents and physicians had a positive experience, and trust was one of the main reasons for parents to consent. Misunderstanding (bad comprehension) was the main reason for refusal. Before birth, three situations can compromise parents’ consent: the mother already consented to participate in other studies, the absence of the father during the interview and the feeling that the baby’s birth is not an imminent possibility.
Confronting parents and physicians’ perspectives in research can help us reach answers to sensitive issues such as content and timing of information. Each different types of study raises different ethical dilemmas for consent that might be discussed in a more individual way.
Dynamic consent management for clinical trials via private blockchain technology

Journal of Ambient Intelligence and Humanized Computing, 14 February 2020
Clinical trials (CTs) are essential for the advancement of medical research, paving the way for the development and adoption of new treatments, and contributing to the evolution of healthcare. An essential factor for the success of a CT is the appropriate management of its participants and their personal data. According to the current regulations, collecting and using personal data from participants must comply with rigorous standards. Therefore, healthcare institutes need to obtain freely given, specific, informed, and unambiguous consent before being able to collect the data. Some of the major limitations of the current technological solutions are the lack of control over the granularity of consent grants, as well as the difficulty of handling dynamic changes of consent over time. In this paper, we present SCoDES, an approach for trusted and decentralized management of dynamic consent in clinical trials, based on blockchain technology (BCT). The usage of blockchain provides a set of features that allow maintaining consent information with trust guarantees while avoiding the need for a dedicated or centralized third trusted party. We provide a full implementation of SCoDES, made available as a self-contained infrastructure, with the possibility to interact with external services, and using hyperledger as a blockchain framework.
Editor’s note: The SCoDES project is an applied research project on blockchains involving five Hautes Ecoles from French-speaking Switzerland… Its goal is to develop knowledge within the field of blockchain and smart contracts by studying and developing practical cases of use and transferring the acquired knowledge to the regional economic actors.

Research to inform the care of neurologically deceased organ donors is complicated by a lack of standards for research consent. In this systematic review, we aim to describe current practices of soliciting consent for participation in prospective studies of neurologically deceased donors, including the frequency and justification for these various models of consent. Among the 74 studies included, 14 did not report on any regulatory review, and 13 did not report on the study consent procedures. Of the remaining 47 studies, 24 utilized a waiver of research consent. The most common justification for a waiver of research consent related to the fact that neurologically deceased donors are not considered human subjects. In conclusion, among studies of neurologically deceased donors, research consent models vary and are inconsistently reported. Consensus and standardization in the application of research consent models will help to advance this emerging field of research.
Remote Consent Clinical Research
Clinical Trials and Practice, 30 October 2019; 1(1) pp 39-41
Recruitment in clinical research trials can be challenging in trials that are time-sensitive and/or are rare disease and critical care trials. One of the hurdles for recruitment in these types of clinical trials is due to the consent process, and the need to have consent of the patient within a certain timeframe, or the patient unable to consent for themselves. This paper will discuss the usage of the utilization of remote consent options for these trials.

We previously validated a visual aid for the use in the consent process for an appendectomy showing improved parental satisfaction and understanding. In this study, we evaluated provider satisfaction and perceived value of using the visual aid.
An IRB approved survey was developed assessing provider experience with use of the visual aid. This was distributed and analyzed via Research Electronic Data Capture (RedCap) Database.
We administered 58 surveys (45% response rate). Participants included faculty (n = 2), fellows (n = 1), residents (n = 6), and physician assistants (n = 17). The visual aid was used > 10 times by 50% of providers. The most common reason for not using the visual aid was not remembering it was available. Nearly half (40%) did not feel the visual aid added any time. 9/20 (45%) felt it added a small amount of time. Slightly over half of providers (52%) felt using the visual aid significantly increased family ability to give informed consent and made the consenting process easier for both providers and families.
Using a visual aid in consenting families for appendectomy does not add significant time and subjectively improves the process for providers and increases provider perception of parental understanding.
The effects of a humorous video on memory for orthodontic treatment consent information
Timothy P. Levine
American Journal of Orthodontics and Dentofacial Orthopedics, February 2020; 157(2) pp 240-244
Communication of treatment information is critical in orthodontics. The challenge lies in doing so effectively such that patients will understand and remember, which is the definition of true informed consent. Previous studies have established that information is more readily remembered when presented using multimedia presentations. Likewise, humor has been shown to increase information retention.
Two videos, 1 humorous (H) and 1 unhumorous (U), were produced with identical information about orthodontic treatment consent. Thirty-eight new orthodontic patients were randomly selected and divided into H (n = 20) and U (n = 18) video groups. Identical questionnaires with multiple-choice responses to judge memory of the content were completed by both groups immediately after watching the video (T1) and 6 weeks later (T2). A one-tailed Welch’s t test was used to analyze the scores.
At T1, there was no significant difference in the scores of the questionnaire between H and U groups, whereas at T2, there was a significant difference between groups. The intragroup score difference was also analyzed, with a significant decrease from T1 to T2 in the U, but not H, group. Subjective questions were also asked regarding content. No significant differences were found between the groups regarding the informativeness of each video; however, willingness to watch again and memorability of the content were significantly higher in the H group.
Patients who received orthodontic treatment information presented with humor retained significantly more of that information after 6 weeks compared with patients who received the same information without humor. Patients who received the humorous content subjectively stated they were more likely to rewatch the video and also found the information presented in this manner to be more memorable.
Multimedia in improving informed consent for caesarean section: A randomised controlled trial

Obstetrics & Gynaecology, 28 January 2020
Multimedia modules have been used as an adjunct to improve patient knowledge and recall for various elective surgical procedures, but have been incompletely evaluated in patients undergoing caesarean section.
To compare the use of a supplementary multimedia module with written information in improving the informed consent process prior to elective caesarean section.
Materials and methods
This was a prospective randomised controlled trial (ACTRN12616000430437). Primary outcomes were knowledge and anxiety scores immediately following the intervention and on the day of surgery. Secondary outcomes were patient satisfaction, length of stay, time to cessation of analgesia, and patient assessment of the consent types.
Seventy‐five patients completed the study. Both multimedia module and written information groups demonstrated a significant increase in knowledge scores with no difference between the groups. In the multimedia‐assisted consent group, scores improved from baseline by +2.31 (P < 0.001) immediately after watching the multimedia module and by +2.41 (P < 0.001) on the day of surgery. In the written information group, scores improved by +1.76 (P < <0.001), and +2.31 (P < 0.001) respectively. There was no adverse impact on anxiety in either group. Patient‐reported understanding (92.4% vs 78.5%, P = 0.001), and helpfulness (90.1% vs 73.3%, P = 0.001) was significantly higher in the multimedia module group than in the written information group. The multimedia module was assessed as ‘slightly too long’ and provided ‘slightly too much information’.
Multimedia modules are a valuable adjunct to traditional processes of obtaining informed consent for elective caesarean section and should be offered and made available to patients prior to surgery.
