Abstract
Background
Symbol communication aids are used by children with little or no intelligible speech as an Augmentative and Alternative Communication strategy. Graphic symbols are used to help support understanding of language and used in symbol communication aids to support expressive communication. The decision making related to the selection of a symbol communication aid for a child is poorly understood and little is known about what language and communication attributes are considered in this selection.
Aim
To identify from the literature the language or communication attributes of graphic symbol communication aids that currently influence AAC practice.
Method and Procedure
A search strategy was developed and searches were performed on a range of electronic databases for papers published since 1970. Quality appraisal was carried out using the CCAT tool and papers rated as weak were not included in the review.
Results
Eleven studies were included in the review reporting data from 66 participants. Weaknesses were identified in most studies that would limit the validity of the results for application to practice. Included studies investigated aspects of vocabulary organization and design, the process of vocabulary selection, and the choice of the symbol system and encoding method. Two studies also evaluated innovative communication aid attributes.
Conclusions
Information from studies reported in the research literature provides a sparse source of information about symbol communication aids from which clinicians, children or family members may make informed decisions.

Abstract
Objective
Previous studies have shown no consistent examinations for testing the ability of patients to consent in hospital emergency departments (EDs). The primary objective of this study was to compare providers’ opinions with 3 capacity assessment tools to determine the ability of medical and psychiatric patients to consent in the ED.
Method
The study was conducted at a level 1 inner-city general hospital ED from June 2016 to October 2017. The study participants comprised a random sample of English-speaking patients aged ≥ 18 years who presented with any medical or psychiatric complaint. Each patient was administered 3 tools: the standard ED consent form, the Aid to Capacity Evaluation (ACE), and the Mini-Mental State Examination. The results of these assessments were then compared to the provider’s opinion of the patient’s ability to provide consent.
Results
A total of 283 patients participated in the study, and 84.4% were able to consent according to providers. There was a high level of consistency with the provider’s assessment and the other assessment tools on the patient’s ability to consent. Most patients, both medical and psychiatric, showed the ability to consent. However, this was less true for psychiatric patients with schizophrenia, as 32.6% (n = 14) were unable to consent.
Conclusions
The study revealed that the ACE capacity assessment was highly consistent with the providers’ assessment for medical (88.3%) and psychiatric patients (80.3%), but not for psychiatric patients with schizophrenia. Using the ACE, patients with schizophrenia presenting to the ED were significantly less able to understand their illnesses (0.01) and treatments (0.04) and thus were less able to give consent.

Abstract
Background
Facing the relentless worsening of their condition, ALS patients are required to make decisions on treatments and end-of-life care. A cognitive impairment showed to be a negative prognostic factor in ALS patients, perhaps affecting the ability to make informed decisions. Notwithstanding its crucial role, the capacity to consent to treatment (CCT) has never been evaluated in these patients.
Objectives
To assess the CCT in an ALS cohort in comparison to a control group, and to study the effects of demographic and clinical variables on this high-level cognitive function.
Methods
102 ALS patients and 106 healthy controls (HC) were enrolled. CCT was assessed using the MacArthur Competence Assessment Tool for Treatment (MAC-CAT-T) and the performance was classified into the three CCT outcomes (full credit, partial credit, no credit). Cognitive and psychological variables were assessed by MMSE, phonemic fluencies, Frontal System Behavioural Scale (FrSBe), and ALS Depression Inventory (ADI). Clinical and demographic variables were analyzed as possible predictors of the MAC-CAT-T outcomes. After a 1-year follow-up, CCT and neuropsychological assessments were repeated.
Results
Most ALS patients (i.e., from 75 to 83% according to the different sub-items) retain full CCT. However, a subpopulation of the ALS patients showed a reduced CCT with respect to the HC. Age, education, phonemic fluency, and depression appeared related to the CCT outcomes. After 1 year, only the reasoning items worsened.
Conclusions
This is a preliminary report suggesting that the large majority of ALS patients can retain full ability to choose between treatment options. However, demographic and neuropsychological variables may affect CCT, pointing to the need for special attention to the consent disclosure in this disease.

Advances and challenges in conducting ethical trials involving populations lacking capacity to consent: A decade in review

Abstract
Informed consent is an essential requirement prior to clinical trial participation, however some ‘vulnerable’ groups, such as people with cognitive impairments and those in medical emergency situations, may lack decisional capacity to consent. This raises ethical and practical challenges when designing and conducting clinical trials involving these populations, who are frequently excluded as a result. Despite recent advances in improving informed consent processes, there has been far less attention paid to the enrolment of adults lacking capacity.
Exclusion criteria are an important determinant of the external validity of clinical trial results. The exclusion of these populations, and consent-based recruitment biases which arise from the challenges of identifying and involving surrogate decision-makers, leads to trials which are not representative of the clinical population.
This article discusses the involvement of adults who lack decisional capacity to consent in clinical trials and presents the advances over the previous decade and the remaining ethical challenges for the inclusion of this under-represented population in research.

Abstract
Background: Child health research comprises complex ethical considerations. Understanding the extent to which the ethical process is reported in child health research is needed to improve reporting. Aims: To identify reportage of ethical considerations in child health research in leading nursing and paediatric journals. Methods: All child health research published between 2015 and 2019 in ten leading nursing journals and two paediatric journals were retrieved and critically appraised for the reportage of informed consent and ethical approval. Results: Eight hundred and fifty-one child health research papers were included. Whilst 544 (79.9%) of the prospective studies mentioned informed consent, only 300 (55.2%) reported that written informed consent was obtained from the participants. Overall, 748 (87.9%) of child health research papers noted obtaining research ethics committee approval. Articles that mentioned financial support were significantly more likely to report informed consent and ethical approval than unfunded studies (all P<0.001). Prospective studies showed higher rates of reportage of ethical approval compared to retrospective studies (P=0.027). Rates of child consent (assent) obtained in different age groups of children ranged from 29.6% to 66.3%. Conclusion: Despite improvements in the reportage of ethical review and approval processes in child health research, consistent and transparent reports are still lacking.

Opt-out consent in children’s emergency medicine research

Abstract
There is global acceptance that individuals should be allowed to decide whether or not to take part in research studies, and to do so after being informed about the nature of the research and the risk that might attach to participation. The process of providing detailed information before seeking consent (formalised by signatures) in advance of undertaking research procedures may not be possible in some circumstances, and sometimes an amended approach may be adopted. The use of opt-out consent has been recognised as a valid and ethical means of recruiting participants to studies particularly with large samples and where the risk to participants is small. However, it is sometimes misunderstood and can be a problematic factor in being accepted by research ethics committees and governing authorities. This may be due partly to differing expectations of the amount of information and support offered, together with the nature of the process that is adopted to ensure that a decision has been made rather than consent simply being assumed. In accordance with ongoing discussions with young people, and following consultation with parents, an opt-out consent strategy including varied means of providing information was employed in a large study of 44,501 cases of children attending emergency or urgent care departments. The study was conducted over more than 12 months in dissimilar emergency departments and an urgent care unit, and was designed to support better decision-making in paediatric emergency departments about whether children need to be admitted to hospital or can be discharged home safely. Robust analysis of the factors that exerted the greatest impact on predicting the need to admit or the safety of discharging children led to a revised version of a an existing tool. In this article we review approaches to consent in research, the nature and impact of opt-out consent, the factors that made this an effective strategy for this study, but also more recent concerns which may make opt-out consent no longer acceptable.

Abstract
Background
Regulations are vague regarding the appropriate decision-maker and authority to consent for children of minor parents participating in clinical trials. In countries with high rates of underage mothers, such as in sub-Saharan Africa, this lack of guidance may affect the rights of potential paediatric participants already bearing increased vulnerability. It can also influence the recruitment and generalizability of the research. We provide evidence and discuss informed consent management in such cases to inform best practice.
Materials and methods
We searched PubMed/MEDLINE, Embase, CINAHL, and Google Scholar for articles published up to March 2019. In total, 4382 articles were screened, of which 16 met our inclusion criteria. Studies addressing informed consent in clinical trials involving children with minor parents in sub-Saharan Africa were included. We performed descriptive and qualitative framework analyses. The review was registered in PROSPERO: CRD42018074220.
Results
Various informed consent approaches were reported. Articles supporting individual consent by minor parents based on emancipation or “mature minor” status lacked evidence in the context of research. National laws on medical care guided consent instead. When no laws or guidance existed an interpretation of the local decision-making culture, including community engagement and collaboration with local ethics committees, defined the informed consent approach.
Conclusions
The review emphasises that the implementation of informed consent for children with minor parents may be variable and hampered by absent or ambiguous clinical trial regulations, as well as divergent local realities. It may further be influenced by the research area and study-specific risks. Clear guidance is required to help address these challenges proactively in clinical trial planning. We provided a set of questions to be considered in the development of an ethically acceptable informed consent approach and proposed information that should be integrated into international clinical trial guidelines.

Abstract
Importance
Obtaining informed consent is an important ethical obligation for clinical research participation that is imperfectly implemented. Research on improving consent processes often focuses on consent forms, but little is known about consent forms’ influence on decision-making compared with other types of engagement.
Objective
To evaluate whether parents decide whether to enroll their children in research before or after they receive the consent form.
Design, Setting, and Participants
An online survey of 88 parents who enrolled or declined to enroll their child in a weight management intervention study between January 2, 2018, and June 24, 2019, was conducted; surveys were completed between February 2, 2018, and July 9, 2019. A 31-item survey asked about impressions of the study throughout the enrollment process, timing of enrollment decisions, and decision-making factors. Responses were summarized descriptively and subgroups were compared using the Fisher exact test or χ2 test.
Main Outcomes and Measures
Self-reported timing of enrollment decision.
Results
A total of 106 parents were approached and gave permission for their contact information to be shared with the study team; 22 additional parents declined to allow their information to be shared, and 24 lost contact with the partner study before they could be asked for permission. A total of 88 parents (67 enrollees, 21 decliners) completed the survey (83% participation rate); 79 of 88 reporting gender (instead of sex, as biological sex was not relevant to survey) information were women (91%), 66 participants (75%) were non-Hispanic White, and 63 participants (72%) had annual household incomes greater than or equal to $70 000. No significant differences in respondent characteristics between enrollees and decliners were identified. Fifty-nine parents (67%) responded that they decided whether to enroll in the weight management study before receiving the consent form. Only 17 of 69 parents (25%) who remembered receiving the consent form responded that it taught them new information.
Conclusions and Relevance
The findings of this study suggest that interventions to improve informed consent forms may have limited influence on decision-making because many research decisions occur before review of the consent form. It appears that regulatory review and interventions to improve decision-making should focus more on early engagement (eg, recruitment materials). Future studies should test timing of decisions in other types of research with different populations and clinical settings.

Abstract
Informed consent can be defined as a freely-given decision or agreement following disclosure of relevant information. This review explores how legislation surrounding informed consent has impacted upon clinical research practices, with a focus on clinical trials involving individuals with the capacity to give consent in the non-emergency setting. We also highlight the challenges which remain with the informed consent process, including those which exist in the era of data protection legislation and genetic research.
Modern ethicists agree that informed consent encompasses three principal factors: disclosure of information, capacity for decision making, and voluntariness. In the context of clinical research, informed consent is now required by regulatory and ethical frameworks as well as by law, and various guidelines govern the practice of informed consent, including the Declaration of Helsinki and the Good Clinical Practice Guidelines. Historically, however, researchers acted paternalistically and, included participants in research without their knowledge or consent. Following societal and political revolution, an autonomy model of consent became prevalent, and individuals become free to make individual choices about whether to participate. Despite this, it is also recognized that an individual’s community has a role in supporting their decision making, and this may be a strong influence, particularly within some societies. Research scandals and controversies and whistle-blowers which exposed unethical practices in the area of informed consent also contributed to changes in societal attitudes and legislation changed as a result. Medical journals also have an established, although indirect, role in strengthening good practices surrounding informed consent.

Abstract
Globally, more than 5 million stillbirths and neonatal deaths occur annually. For many, the cause of death (CoD) is unknown. Minimally invasive tissue sampling (MITS) has been increasingly used in postmortem examinations for ascertaining the CoD in stillbirths and neonates. Our study compared the counseling and consent methods used in MITS projects in five countries in Africa and south Asia. Key informant interviews were conducted with researchers to describe the characteristics and backgrounds of counselors, the environment and timing of consent and perceived facilitators and barriers encountered during the consent process. Counselors at all sites had backgrounds in social science, psychology and counseling or clinical expertise in obstetrics/gynecology or pediatrics. All counsellors received training about techniques for building rapport and offering emotional support to families; training duration and methods differed across sites. Counselling environments varied significantly; some sites allocated a separate room, others counselled families at the bedside or nursing stations. All counsellors had a central role in explaining the MITS procedure to families in their local languages. Most sites did not use visual aids during the process, relying solely on verbal descriptions. In most sites, parents were approached within one hour of death. The time needed for decision making by families varied from a few minutes to 24 h. In most sites, extended family took part in the decision making. Because many parents wanted burial as soon as possible, counsellors ensured that MITS would be conducted promptly after receiving consent. Barriers to consent included decreased comprehension of information due to the emotional and psychological impact of grief. Moreover, having more family members engaged in decision-making increased the complexity of counselling and achieving consensus to consent for the procedure. While each site adapted their approach to fit the context, consistencies and similarities across sites were observed.
