Abstract
Background
The goal of the informed consent process is to provide patients with the necessary educational information, defend their autonomy, and allow active involvement in treatment planning and decision-making. The informed consent process must not only describe the operation in full, but also provide information on the procedure’s rationale, alternative therapies, associated benefits, risks, and complications. However, the process of acquiring informed consent is fraught with issues.
Objective
This research aims to assess if presenting information about third molar extraction via an informative, narrated, animated video changes a patient s perception of the consent process for third molar extraction when compared to conventional verbal/written consent. The outcomes that are evaluated include patient understanding, patient satisfaction and patient anxiety.
Methods
In this post test-only control clinical trial patients scheduled for surgical removal of an impacted mandibular third molar that fulfilled the predetermined criteria were invited to participate in the study. The criterion variable was the presentation of an animated information consent video. Participants were randomly assigned into 2 equal groups receiving either verbal consent or video-assisted consent. After signing the consent form patients then filled out an electronic questionnaire rating their experience of the consent process. At the postoperative review, 7-14 days after the procedure, patients were asked to fill out a questionnaire rating their experience of the consent retrospectively. The outcome variables were patients self-reported level of understanding, patient anxiety measured on the Dental Anxiety Scale and patient satisfaction. The data were analysed with Pearson s chi-squared tests, Fisher s Exact test, and linear regression analysis.
Results
Ninety patients fulfilled the inclusion criteria and were included in the study. The video-assisted group reported higher levels of understanding of the proposed procedure (P<0.001) and the associated risks/complications (P<0.004 ). Patients were more satisfied with information delivered to them via video. 98% of patients in the video consent group felt that the video-assisted consent was beneficial. There was no statistically significant change in the reported level of anxiety when video-assisted consent was used.
Conclusion
The present study suggests that video-assisted consent may improve patients level of understanding of the potential postoperative risks and complications involved in surgical removal of an impacted mandibular third molar. This improved understanding did not increase patients dental anxiety compared with conventional verbal/written consent but improved patients level of satisfaction with the amount of information that they received.

Abstract
Background and objectives
In 2019, two Canadian provinces became the first jurisdictions in North America to pass deemed consent legislation to increase deceased organ donation and transplantation rates. We sought to explore the perspectives of the deemed consent legislation for organ donation in Canada from the viewpoint of individuals commenting on press articles.
Design, setting, participants, & measurements
In this qualitative descriptive study, we extracted public comments regarding deemed consent from online articles published by four major Canadian news outlets between January 2019 and July 2020. A total of 4357 comments were extracted from 35 eligible news articles. Comments were independently analyzed by two research team members using a conventional content analysis approach.
Results
Commenters’ perceptions of the deemed consent legislation for organ donation in Canada predominantly fit within three organizational groups: perceived positive implications of the bills, perceived negative implications of the bills, and key considerations. Three themes emerged within each group that summarized perspectives of the proposed legislation. Themes regarding the perceived positive implications of the bills included majority rules, societal effect, and prioritizing donation. Themes regarding the perceived negative implications of the bills were a right to choose, the potential for abuse and errors, and a possible slippery slope. Improving government transparency and communication, clarifying questions and addressing concerns, and providing evidence for the bills were identified as key considerations.
Conclusions
If deemed consent legislation is meant to increase organ donation and transplantation, addressing public concerns will be important to ensure successful implementation.

Abstract
Background
This study was an ex-ante cost-utility analysis of deemed consent legislation for deceased organ donation in Nova Scotia, a province in Canada. The legislation became effective in January 2021. The study’s objective was to assess the conditions necessary for the legislation change’s cost-effectiveness compared to expressed consent, focusing on kidney transplantation (KT).
Method
We performed a cost-utility analysis using a Markov model with a lifetime horizon. The study was from a Canadian payer perspective. The target population was patients with end-stage kidney disease (ESKD) in Atlantic Canada waitlisted for KT. The intervention was the deemed consent and accompanying health system transformations. Expressed consent (before the change) was the comparator. We simulated the minimum required increase in deceased donor KT per year for the cost-effectiveness of the deemed consent. We also evaluated how changes in dialysis and maintenance immunosuppressant drug costs and living donor KT per year impacted cost-effectiveness in sensitivity analyses.
Results
The expected lifetime cost of an ESKD patient ranged from $177,663 to $553,897. In the deemed consent environment, the expected lifetime cost per patient depended on the percentage increases in the proportion of ESKD patients on the waitlist getting a KT in a year. The incremental cost-utility ratio (ICUR) increased with deceased donor KT per year. Cost-effectiveness of deemed consent compared to expressed consent required a minimum of a 1% increase in deceased donor KT per year. A 1% increase was associated with an ICUR of $32,629 per QALY (95% CI: − $64,279, $232,488) with a 81% probability of being cost-effective if the willingness-to-pay (WTP) was $61,466. Increases in dialysis and post-KT maintenance immunosuppressant drug costs above a threshold impacted value for money. The threshold for immunosuppressant drug costs also depended on the percent increases in deceased donor KT probability and the WTP threshold.
Conclusions
The deemed consent legislation in NS for deceased organ donation and the accompanying health system transformations are cost-effective to the extent that they are anticipated to contribute to more deceased donor KTs than before, and even a small increase in the proportion of waitlist patients receiving a deceased donor KT than before the change represents value for money.

Abstract
Informed decision-making (IDM) is considered an important ethical and legal requirement for population-based screening. Governments offering such screening have a duty to enable invitees to make informed decisions regarding participation. Various views exist on how to define and measure IDM in different screening programmes. In this paper we first address the question which components should be part of IDM in the context of cancer screening. Departing from two diverging interpretations of the value of autonomy—as a right and as an ideal—we describe how this value is operationalized in the practice of informed consent in medicine and translate this to IDM in population-based cancer screening. Next, we specify components of IDM, which is voluntariness and the requirements of disclosure and understanding. We argue that whereas disclosure should contain all information considered relevant in order to enable authentic IDM, understanding of basic information is sufficient for a valid IDM. In the second part of the paper we apply the capability approach in order to argue for the responsibility of the government to warrant equal and real opportunities for invitees for IDM. We argue that additional conditions beyond mere provision of information are needed in order to do so.

Abstract
The European Commission (Commission) put forward an ambitious proposal package of new legislation for the digital economy, including the Digital Markets Act, the Digital Services Act, or the Data Governance Act. Despite their different scopes, they all share a recurring topic: the relevance of (personal) data in enabling a data-intensive economic model around data sharing and the role of data subjects in granting permission to do so. As such, the purpose of this article is to explore how the Commission and other EU institutions intended to strengthen consent in these novel data regulations through technological tools but also novel assistance duties, but also the potential shortcoming around this approach.

Journal of Healthcare Quality Research, 27 September 2022
Abstract
Objective
To evaluate the access, development, and quality of consents forms for clinical practice within the Spanish Public Hospitals.
Method
A cross-sectional study was conducted in a two-stage process (January 2018–September 2021). In stage 1, A nationwide survey was undertaken across all public general hospitals (n = 223) in the Spanish Healthcare System. In stage 2, Data was taken from the regional health services websites and Spanish regulations. Health Regional Departments were contacted to verify the accuracy of the findings. Data was analyzed using a descriptive and inferential statistics (frequencies, percentages, Chi-square & Fisher’s exact tests).
Results
The response rate was 123 (55.16%) of Spanish Public Hospitals. The results revealed a range of hospital departments involved in the development of consent documents and the absence of a standardized approach to consent forms nationally. Consent audits are undertaken in 43.09% hospitals and translation of written consents into other languages is limited to a minority of hospitals (35.77%). The validation process of consent documentation is not in evidence in 13% of Spanish Hospitals. Regional Informed Consent Committees are not place in the majority (70.7%) of hospitals. Citizens can freely access to consent documents through the regional websites of Andalusia and Valencia only.
Conclusion
Variability is found on access, development and quality of written consent across the Spanish Public Hospitals. This points to the need for a national informed consent strategy to establish policy, standards and an effective quality control system. National audits at regular intervals are necessary to improve the consistency and compliance of consent practice.

Abstract
Introduction
Blood transfusion warrants written informed consent from the patient. However, patients have poor knowledge regarding blood transfusions as evidenced by nonstandardized information retained by patients from the informed consent discussion. The problem stems from suboptimal patient knowledge on the elements of informed consent. This study describes the development and validation of a new questionnaire to assess the knowledge on informed consent for blood transfusion from the patients’ perspective.
Subjects and Methods
The development phase consisted of literature review, small group discussion, expert review meeting, content, and face validity. We evaluated the psychometric properties of Informed Consent for Blood Transfusion Questionnaire (ICBTQ) using reliability test and item response theory among a sample of 95 patients in Hospital Universiti Sains Malaysia.
Results
ICBTQ was formulated to include sociodemographic and knowledge sections. ICBTQ possessed excellent content validity. The face validity index (FVI) of clarity and comprehension were both 0.97. Thus, the universal FVI was 0.96. One item was added following the advice given by one of the content experts. ICBTQ had excellent face validity. For the validation phase, ICBTQ demonstrated an acceptable Cronbach’s Alpha value. One item was omitted in view of low corrected item-total correlation. In the item response theory (IRT) analysis, ICBTQ exhibited good difficulty and discriminatory indexes. Assessments of item-fit indicated that all items of the model were well-fitted.
Conclusions
Based on the IRT and reliability analysis, the knowledge section of the ICBTQ was psychometrically valid to be used among patients.
