Abstract
While the majority of population-level genome sequencing initiatives claim to follow the principles of informed consent, the requirements for informed consent have not been-well defined in this context. In fact, the implementation of informed consent differs greatly across these initiatives – spanning broad consent, blanket consent, and tiered consent among others. As such, this calls for an investigation into the requirements for consent to be “informed” in the context of population genomics. One particular strategy that claims to be fully informed and to continuously engage participants is called “dynamic consent”. Dynamic consent is based on a personalised communication platform that aims to facilitate the consent process. It is oriented to support continuous two-way communication between researchers and participants. In this paper, we analyze the requirements of informed consent in the context of population genomics, review various current implementations of dynamic consent, assess whether they fulfill the requirement of informed consent, and, in turn, enable participants to make autonomous and informed choices on whether or not to participate in research projects.

Abstract
Very few attempts have been made to survey patient opinions, particularly regarding the use of residual biospecimens and health information in research, to clarify their values. We conducted a questionnaire survey that targeted outpatients of a university hospital to gauge their awareness levels and understand patient perspectives on research that uses these items. Few patients felt that obtaining individual consent for each research study was necessary. Most patients expressed the view that researchers should be obligated to inform them about the research use of their items and be subject to self-directed rules (including sanctions). The research community should try to obtain “societal consent regarding an opt-out system” from the public. A salient value-sharing-based governance structure is necessary for obtaining public trust.

Abstract
In the last decade, research in transplant medicine has focused on developing interventions in the management of the deceased organ donor to improve the quality and quantity of transplantable organs. Despite the promise of interventional donor research, there remain debates about the ethics of this research, specifically regarding gaining research consent. Here, we examine the concerns and ambiguities around consent for interventional donor research, which incorporate questions about who should consent for interventional donor research and what people are being asked to consent for. We highlight the US and UK policy responses to these concerns and argue that, whereas guidance in this area has done much to clarify these ambiguities, there is little consideration of the nature, practicalities and context around consent in this area, particularly regarding organ donors and their families. We review wider studies of consent in critical care research and social science studies of consent in medical research, to gain a broader view of consent in this area as a relational and contextual process. We contend a lack of consideration has been given to: what it might mean to consent to interventional donor research; how families, patients and health professionals might experience providing and seeking this consent; who is best placed to have these discussions; and the socio-institutional contexts affecting these processes. Further, empirical research is required to establish an ethical and sensitive model for consent in interventional donor research, ensuring the principles enshrined in research ethics are met and public trust in organ donation is maintained.

Abstract
This paper addresses psychological factors that might interfere with informed consent on the part of stable patients as potential early-phase clinical trial participants. Thirty-six semistructured interviews with patients who had either diabetes or gout were conducted. We investigated stable patients’ attitudes towards participating in a fictitious first-in-human trial of a novel intervention. We focused on an in-depth analysis of those statements and explanations that indicated the existence of psychological factors impairing decision-making capacity. Three main themes emerged: insufficient comprehension of the inherent logic of clinical trials (actual comprehension), the recourse to trust over comprehension (prioritization of trust), and visceral factors that override deliberative process (visceral factors). Overall, our results indicate a limited psychological capacity on the part of stable patients to meet the requirements of informed consent as set by Declaration of Helsinki. A redesigned informed consent procedure should take account of these psychological realities.

Abstract
Background
The informed consent is a defining moment that should allow patients to understand their condition, what procedure they are undergoing, and what consequences may follow. This process should foster trust and promote confidence, without increasing patients’ anxiety. New immersive 3D imaging technologies may serve as a tool to facilitate this endeavor.
Methods
In a prospective, single-center, randomized controlled clinical trial (SPLICE Study: Surgical Planning and Informed Consent Study; ClinicalTrials.gov NCT03503487), 40 patients undergoing surgery for intracranial tumors were enrolled. After undergoing a traditional surgical informed consent acquisition, 33 patients were randomized 1:1:1 to 3 groups: in 2 experimental groups, patients underwent a 3D, immersive informed consent with two different surgical planners (group 1 and group 2); in the control group, patients underwent an informed consent supported by traditional 2D radiological images.
Results
Patients in the experimental groups appreciated this communication experience, while their objective comprehension was higher ((score mean (SD)): group 1 82.65 (6.83); group 2 77.76 (10.19)), as compared with the control group (57.70 (12.49); P < 0.001). Subjective comprehension and anxiety levels did not differ between experimental groups and control group.
Conclusions
3D virtual reality can help surgeons and patients in building a better relationship before surgery; immersive 3D-supported informed consent improves patients’ comprehension of their condition without increasing anxiety. This new paradigm may foster trust between surgeons and patients, possibly restraining medical-legal acts.

Abstract
Objective
Bariatric surgery is not a risk-free procedure and requires lifelong patient compliance in the postoperative period. Although the risks involved in bariatric surgery and the importance of lifelong follow-ups in the postoperative period are explained to patients in detail through verbal and written informed consent, the strong desire for weight loss can sometimes cause patients and their families to be ignorant of the mentioned issues preoperatively. The objective of this study is to evaluate the effectiveness of preoperative informational videos at improving the comprehension of informed consent content in bariatric surgery candidates.
Materials and Methods
A total of 74 bariatric surgery candidates were randomized into two groups. The first group was given a usual verbal-written informed consent. The second group got an additional informing video presentation informed consent, in addition to the usual verbal-written informed consent. Then, both groups got a questionnaire evaluating their knowledge of bariatric surgery informed consent. The correct response scores and their relationship with patient demographics were analyzed.
Results
Both groups had similar demographic features. Video-presented group had higher scores in questionnaire (11.3 ± 2.3 versus 9.4 ± 1.7, p = 0.001). Subgroup analysis showed that health care workers (12.5 ± 1.9 versus 10.3 ± 2.2, p = 0.005) and university graduates (11.6 ± 2.4 versus 10.1 ± 2.1, p = 0.03) got better results in the questionnaire. In multivariate analysis, video-assisted informing was found to be the only independent variable for high questionnaire scores (p = 0.0001).
Conclusions
This study showed that video-assisted informed consent improves patients’ comprehension prior to bariatric surgery. We recommend routine preoperative video-assisted informing for bariatric surgery candidates in addition to usual verbal-written informed consent.

Abstract
Obtaining informed consent for bloodspot research from newborn screening is particularly challenging due to the hectic environment of the postnatal period and the relatively abstract nature of future, unspecified research on the biospecimens. A randomized controlled trial was conducted in three Michigan hospitals to compare two different consent processes (video and interactive tablet “app”) with standard brochure-based consent in the Michigan BioTrust for Health. Results indicated higher knowledge scores for the video and app groups as well as significantly higher scores on satisfaction, amount of information, and clarity with the information provided. More research is needed to find the right amount of information for informed decision-making, and additional feasibility studies are needed to assess implementation strategies.

Abstract
Dynamic consent has been proposed as a strategy for addressing the limitations of traditional, broad consent for biobank participation. Although the argument for dynamic consent has been made on theoretical grounds, empirical studies evaluating the potential utility of dynamic consent are needed to enhance deliberations about the merits of dynamic consent. Few studies have assessed such considerations as whether donor preferences may change over time or if participants would use a dynamic consent mechanism to modify preferences when they change. We administered a 66-item survey to participants in a large DNA biobank. The survey sought to gauge the stability of donor preferences specified at the time of biobank enrollment, specifically the stability of donors’ preference regarding posthumous availability of biospecimens to next-of-kin. We received 1164 completed surveys for a response rate of 72%. Forty percent of respondents indicated a preference regarding sample availability on the survey (T2) that was inconsistent with the preference they had expressed when they enrolled in the biobank (T1). Most (94%) individuals with inconsistent preferences regarding sample availability had initially restricted sample availability at T1 but were comfortable with broader availability when asked at the time of the survey (T2). Our findings demonstrate that preferences regarding sample use expressed at the time of enrollment in a DNA biobank may not be reliable indicators of donor preferences over time. These findings lend empirical support to the case for a dynamic consent model in which biobank participants are approached over time to clarify their views regarding sample use.

Abstract
Objective
This review will identify and map existing evidence on current approaches to determining decision-making capacity in older adults. It will provide a summary of available evidence and policies and identify gaps in research.
Introduction
Assessment of decision-making capacity is emerging as an important issue in society and healthcare. It is considered an ethically challenging area of clinical practice, and issues with implementation have been identified internationally. With the aging population increasing globally, approaches to assess and support decision-making are becoming more pertinent.
Inclusion criteria
This scoping review will consider studies on assessment approaches and procedures that are used to evaluate the decision-making capacity of older adults, aged 60 years and over. It will include those with age-related cognitive impairment, dementia, and neurodegenerative conditions. Quantitative, qualitative, and mixed-methods studies along with gray literature, including expert opinions, policies reports, and practice guides, will be included.
Methods
The JBI scoping review methodological framework will be used. The review will also be conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) checklist for scoping reviews. The following major healthcare databases will be searched: MEDLINE, PsycINFO, Embase, CINAHL, Cochrane Databases, Web of Science, and Scopus. The search will cover studies published in English from January 2000 to the present date. Titles and abstracts will be screened against inclusion criteria. Data will be extracted using a form developed for this review. A stakeholder consultation meeting will be held to provide feedback on the findings.

Abstract
Introduction
Persistent misconceptions of frailty and dementia in geriatric patients impact physician-patient communication and leave patients vulnerable to disempowerment. Our study examines the consenting process in an orthogeriatric trauma patient population to determine if there is a relationship between increased age at presentation and utilization of health care proxies (HCPs) for surgical procedure consent.
Methods
We retrospectively reviewed medical records of patients aged 65 and older admitted for an operative fracture between 2013 and 2016. Patients were considered decision-making capable if there was absence of history of cognitive impairment prior to surgical consent and if the patients screened negative in a pre-surgical Confusion Assessment Method (CAM) and Mini-Cog Assessment. Data was analyzed via chi-squared and t-test analysis in SPSS.
Results
510 patients were included, and 276 (54.1%) patients were deemed capable of consent. 27 (9.8%) decision-making capable patients had HCPs consent for surgery. 20 of the 27 (74.1%) were 80 years of age or older and 7 patients between 70 and 79 had HCP consent. (p=0.07). HCP consent was significant for age (p<0.001), income level (p=0.03), and HCP physically present at consult (p<0.001). Additionally, language other than English was found to be a significant predictor of HCP consent (p=0.035).
Conclusion
It is concerning that cognitively intact geriatric orthopaedic trauma patients are not always consented for their own surgical procedures. Factors including age, income, and language contribute to increased risk of HCP consent. Increased physician vigilance and adoption of institutional consenting guidelines can reinforce appropriate respect of geriatric patients’ consenting capacity.
