Informed consent in paediatric critical care research--a South African perspective

Beyond translations, perspectives for researchers to consider to enhance comprehension during consent processes for health research in sub-saharan Africa: a scoping review

BACKGROUND

Literature on issues relating to comprehension during the process of obtaining informed consent (IC) has largely focused on the challenges potential participants can face in understanding the IC documents, and the strategies used to enhance comprehension of those documents. In this review, we set out to describe the factors that have an impact on comprehension and the strategies used to enhance the IC process in sub-Saharan African countries.

METHODS

From November 2021 to January 2022, we conducted a literature search using a PRISMA tool. We searched electronic databases (PubMed, EMBASE, EBSCOHOST) to identify relevant peer reviewed studies. We then reviewed the references of these articles to find additional literature that might have been missed through the initial search. We were particularly interested in full text articles in English that focused on the IC process in SSA published between 2006 and 2020. We included systematic reviews, and studies from Western and Asian countries that included data about SSA. We excluded articles that focused on medical interventions and studies that did not require IC.

RESULTS

Out of the 50 studies included most were multi-country (n = 13) followed by single country studies in South Africa (n = 12); Kenya, Tanzania, Uganda (n = 5) each; Gambia, Ghana and Nigeria (n = 2)each ; and one each for Botswana, Malawi, Mali, Mozambique. We identified three areas of focus: (1) socio-cultural factors affecting IC; (2) gaps in the ethical and legal frameworks guiding the IC process; and (3) strategies used to improve participants' understanding of IC.

CONCLUSION

Our review showed wide recognition that the process of achieving IC in SSA is inherently challenging, and there are limitations in the strategies aimed at improving comprehension in IC. We suggest that there is a need for greater flexibility and negotiation with communities to ensure that the approach to IC is suited to the diverse socio-cultural contexts. We propose moving beyond the literal translations and technical language to understanding IC comprehension from the participants' perspectives and the researchers' views, while examining contextual factors that impact the IC process.

Rapid Genome Sequencing: Consent for New Technologies in the Neonatal Intensive Care Context

The clinical utility of rapid genome sequencing (rGS) in critically unwell infants has been consistently demonstrated, and there are calls for rGS to be implemented as a first-line test in the NICU. A diagnosis from rGS can enable rapid initiation of precision treatment, making it potentially lifesaving. However, in many patients rGS leads to the diagnosis of severe and life-limiting conditions, prompting discussion with families about withdrawal of life-sustaining treatment. The complexity of information about rGS, together with the heightened emotions of parents in the NICU, poses significant challenges for informed decision making in this context. We present a case where both parents are unable to provide informed consent, and the treating team must decide whether to proceed with rGS. Our discussion highlights the important differences between genome sequencing and other types of genetic testing, and the crucial role played by pre-test counseling in facilitating informed consent and preparing parents for a range of possible outcomes. We then discuss the consent paradigms at play in NICUs; whereas admission generally comes with an understanding that the treating team will perform interventions thought to be in the best interest of the child, rGS is substantially different because of its long-term implications for patients and family members. Finally, we look at the ethical interplay between parental consent and the interests of the child. We conclude by showing how cases like this are resolved at our tertiary center and how they may be resolved differently in future.

The ethical considerations for emergency care research in low- and middle-income countries: A scoping review of the published literature

INTRODUCTION

Research studies on emergency care in low- and middle-income countries (LMICs) face many ethical considerations, including obtaining valid informed consent from vulnerable patients. This study aims to describe the body of literature related to the ethical considerations associated with emergency care research in low- and middle-income settings.

METHODS

A scoping review was conducted to identify literature published between 2000 and 2020 related to ethical considerations associated with emergency care research in the LMIC setting. Titles and abstracts were screened in duplicate, and full texts were reviewed and extracted by the principal author.

RESULTS

In total, 1087 articles were identified and 17 articles were included. Major themes identified in the literature included risk versus benefit assessments, patient vulnerabilities, consent, community engagement, clinical roles, ancillary care provision, and regulation of research. Alternative models of consent are often used in emergency care research, including surrogate consent, community consent, and waiver of consent. Challenges and best practices with these alternative models of consent in LMICs are discussed.

DISCUSSION

Gaps remain in the literature describing the ethics of emergency care research in LMICs, including clear guidelines for protecting vulnerable patients and designing ethical consent processes. Best practices identified include community engagement for designing research studies, identifying acceptable risk profiles, and allocating benefits. Continuous and rigorous assessment of the quality of consent is also needed.

Consent in children's intensive care: the voices of the parents of critically ill children and those caring for them

Despite its invasive nature, specific consent for general anaesthesia is rarely sought-rather consent processes for associated procedures include explanation of risk/benefits. In adult intensive care, because no one can consent to treatments provided to incapacitated adults, standardised consent processes have not developed. In paediatric intensive care, despite the ready availability of those who can provide consent, no tradition of seeking it exists, arguably due to the specialty's evolution from anaesthesia and adult intensive care. With the current Montgomery-related focus on consent, this seems untenable. We undertook a qualitative study in a specialist children's hospital colocated paediatric/neonatal intensive care (same medical team) in which parental acceptance of admission and entailed procedures is considered implied by virtue of that admission. Semistructured interviews were carried out with both staff and parents to investigate their views about consent, the current system and a proposed blanket consent system, in which parents actively consent at admission to routine procedures. Divergent views emerged: staff were worried that requiring consent at admission might prove a further emotional burden, whereas parents found providing consent a way of coping, feeling empowered and maintaining control. Inconsistencies were found in the way consent is obtained for your routine procedures. Practice does seem inconsistent with contemporary consent standards for medical intervention. Our findings support the introduction of a blanket consent system at admission together with ongoing bedside dialogue to ensure continuing consent. Both parents and staff expressed concern about avoiding possible harmful delays to children due to parental emotional overload and language difficulties.

Barriers and Facilitators to Obtaining Informed Consent in a Critical Care Pediatric Research Ward in Southern Malawi

Informed consent is an ethical requirement in clinical research. Obtaining informed consent is challenging in resource-constrained settings. We report results of a formative qualitative study that examined factors that facilitate and hinder informed consent for clinical research among critically ill children in Malawi. We argue that truly informed consent in a pediatric intensive care unit (PICU) is challenged by parental distress, time constraints when balancing care for critically ill patients with research-related tasks, and social hierarchies and community mistrust toward certain research procedures. We interviewed health care providers and parents of children attending a critical care unit to identify potential challenges and solicit strategies for addressing them. Providers and caregivers suggested practical solutions to enhance research participant understanding of clinical trial research, including the use of visual materials, community engagement strategies, and using patients as advocates in promoting understanding of research procedures.

Emergency care research ethics in low-income and middle-income countries

A large proportion of the total global burden of disease is caused by emergency medical conditions. Emergency care research is essential to improving emergency medicine but this research can raise some distinctive ethical challenges, especially with regard to (1) standard of care and risk–benefit assessment; (2) blurring of the roles of clinician and researcher; (3) enrolment of populations with intersecting vulnerabilities; (4) fair participant selection; (5) quality of consent; and (6) community engagement. Despite the importance of research to improve emergency care in low-income and middle-income countries (LMICs) and the widely acknowledged ethical challenges, very little has been written on the ethics of emergency care research in LMICs. This paper examines the ethical and regulatory challenges to conducting emergency care research with human participants in LMICs. We outline key challenges, present potential solutions or frameworks for addressing these challenges, and identify gaps. Despite the ethical and regulatory challenges, conducting high-quality, ethical emergency care research in LMICs is possible and it is essential for global health.

Cultural considerations for informed consent in paediatric research in low/middle-income countries: a scoping review

INTRODUCTION

Conducting research with children in low/middle-income countries (LMIC) requires consideration of socioeconomic inequalities and cultural and linguistic differences. Our objective was to survey the literature on informed consent in paediatric LMIC research, assessing for practical guidance for culturally and linguistically appropriate procedures.

METHODS

We conducted a scoping review on informed consent in paediatric LMIC research searching the PubMed, Web of Science and PsycINFO databases. Eligible articles were published in English, from any date range, of any study design or format.

RESULTS

The search identified 2027 references, of which 50 were included in the analysis following full-text review. Reviewed guidelines emphasised individual, informed and voluntary consent from parents and caregivers. Reviewed articles provided detailed practical guidance on adapting these guiding principles to LMIC settings, including considerations for community engagement, verbal or other alternative consent procedures for low-literacy settings or less commonly spoken languages and guarding against therapeutic misconception by caregivers. There was uncertainty, however, on how to best protect individual autonomy, especially when influenced by gender dynamics, leadership hierarchies or the social status of researchers themselves. There was, furthermore, limited research discussing the special case of research involving adolescents or of procedures for documenting assent by participating children.

CONCLUSIONS

A scoping review of paediatric research in LMICs revealed substantial guidance on several features of culturally appropriate informed consent. However, additional research and guidance is needed, especially in the areas of gender imbalances, research with adolescents and children's own assent to participate in research.

Ethical considerations in forensic genetics research on tissue samples collected post-mortem in Cape Town, South Africa

BACKGROUND

The use of tissue collected at a forensic post-mortem for forensic genetics research purposes remains of ethical concern as the process involves obtaining informed consent from grieving family members. Two forensic genetics research studies using tissue collected from a forensic post-mortem were recently initiated at our institution and were the first of their kind to be conducted in Cape Town, South Africa.

MAIN BODY

This article discusses some of the ethical challenges that were encountered in these research projects. Among these challenges was the adaptation of research workflows to fit in with an exceptionally busy service delivery that is operating with limited resources. Whilst seeking guidance from the literature regarding research on deceased populations, it was noted that next of kin of decedents are not formally recognised as a vulnerable group in the existing ethical and legal frameworks in South Africa. The authors recommend that research in the forensic mortuary setting is approached using guidance for vulnerable groups, and the benefit to risk standard needs to be strongly justified. Lastly, when planning forensic genetics research, consideration must be given to the potential of uncovering incidental findings, funding to validate these findings and the feedback of results to family members; the latter of which is recommended to occur through a genetic counsellor.

CONCLUSION

It is hoped that these experiences will contribute towards a formal framework for conducting forensic genetic research in medico-legal mortuaries in South Africa.

Qualitative evaluation of a deferred consent process in paediatric emergency research: a PREDICT study

BACKGROUND

A challenge of conducting research in critically ill children is that the therapeutic window for the intervention may be too short to seek informed consent prior to enrolment. In specific circumstances, most international ethical guidelines allow for children to be enrolled in research with informed consent obtained later, termed deferred consent (DC) or retrospective consent. There is a paucity of data on the attitudes of parents to this method of enrolment in paediatric emergency research.

OBJECTIVES

To explore the attitudes of parents to the concept of DC and to expand the knowledge of the limitations to informed consent and DC in these situations.

METHOD

Children presenting with uncomplicated febrile seizures or bronchiolitis were identified from three separate hospital emergency department databases. Parents were invited to participate in a semistructured telephone interview exploring themes of limitations of prospective informed consent, acceptability of the DC process and the most appropriate time to seek DC. Transcripts underwent inductive thematic analysis with intercoder agreement, using Nvivo 11 software.

RESULTS

A total of 39 interviews were conducted. Participants comprehended the limitations of informed consent under emergency circumstances and were generally supportive of DC. However, they frequently confused concepts of clinical care and research, and support for participation was commonly linked to their belief of personal benefit.

CONCLUSION

Participants acknowledged the requirement for alternatives to prospective informed consent in emergency research, and were supportive of the concept of DC. Our results suggest that current research practice seems to align with community expectations.

Exploring the experiences of substitute decision-makers with an exception to consent in a paediatric resuscitation randomised controlled trial: study protocol for a qualitative research study

INTRODUCTION

Prospective informed consent is required for most research involving human participants; however, this is impracticable under some circumstances. The Tri-Council Policy Statement: Ethical Conduct for Research Involving Humans (TCPS) outlines the requirements for research involving human participants in Canada. The need for an exception to consent (deferred consent) is recognised and endorsed in the TCPS for research in individual medical emergencies; however, little is known about substitute decision-maker (SDM) experiences. A paediatric resuscitation trial (SQUEEZE) (NCT01973907) using an exception to consent process began enrolling at McMaster Children's Hospital in January 2014. This qualitative research study aims to generate new knowledge on SDM experiences with the exception to consent process as implemented in a randomised controlled trial.

METHODS AND ANALYSIS

The SDMs of children enrolled into the SQUEEZE pilot trial will be the sampling frame from which ethics study participants will be derived.

DESIGN

Qualitative research study involving individual interviews and grounded theory methodology.

PARTICIPANTS

SDMs for children enrolled into the SQUEEZE pilot trial.

SAMPLE SIZE

Up to 25 SDMs. Qualitative methodology: SDMs will be invited to participate in the qualitative ethics study. Interviews with consenting SDMs will be conducted in person or by telephone, taped and professionally transcribed. Participants will be encouraged to elaborate on their experience of being asked to consent after the fact and how this process occurred.

ANALYSIS

Data gathering and analysis will be undertaken simultaneously. The investigators will collaborate in developing the coding scheme, and data will be coded using NVivo. Emerging themes will be identified.

ETHICS AND DISSEMINATION

This research represents a rare opportunity to interview parents/guardians of critically ill children enrolled into a resuscitation trial without their knowledge or prior consent. Findings will inform implementation of the exception to consent process in the planned definitive SQUEEZE trial and support development of evidence-based ethics guidelines.
