A Qualitative Study of Physician Perspectives on Prognostication in Neonatal Hypoxic Ischemic Encephalopathy

Parents' Experiences of Therapeutic Hypothermia for Neonates With Hypoxic-Ischemic Encephalopathy (HIE): A Single-Center Cross-Sectional Study

BACKGROUND AND OBJECTIVES

The purpose of the study is to assess parental experiences of therapeutic hypothermia for moderate to severe hypoxic-ischemic encephalopathy with the goal of improving local clinical practice guidelines and fostering family-integrated care in neonates with hypoxic-ischemic encephalopathy.

METHODS

This single-center retrospective cross-sectional study included neonates and their parents registered in the Swiss National Asphyxia and Cooling Register between 2011 and 2021. Based on a literature review, an anonymous survey of parents of neonates with hypoxic-ischemic encephalopathy was developed and conducted using an online survey tool. Descriptive statistics were used to analyze the survey results.

RESULTS

The overall response rate to this survey was 64% (46/72). Sufficient information about hypoxic-ischemic encephalopathy was reported by 78% (36/46) of parents and sufficient information about the process of therapeutic hypothermia by 87% (40/46) of parents. The majority of parents indicated the need for, and at least a satisfactory perception of, professional (91%; 42/46) and emotional (87%; 40/46) support. Parents identified fostering family involvement and regular family communication that focuses on family integrated care as areas for improvement.

CONCLUSIONS

There is still an unmet need for multidisciplinary teams to provide professional, empathetic, high quality, and family-integrated care to families with a neonate receiving therapeutic hypothermia for moderate or severe hypoxic-ischemic encephalopathy.

Evolution of Feeding and Developmental Outcomes in Infants With Moderate Hypoxic-Ischemic Encephalopathy: A Pilot Study

The purpose of the study was to describe the evolution of outcomes among full-term infants with moderate hypoxic-ischemic encephalopathy (HIE); from their early swallowing and feeding abilities during hospitalization, to their later developmental outcomes at 6 and 12 months. Four participants with moderate HIE were recruited. Early feeding and swallowing were assessed using the Neonatal Feeding Assessment Scale and video fluoroscopic swallow studies. Developmental assessments were conducted at 6 and 12 months using the Rossetti Infant-Toddler Language Scale and Vineland-3 Scale. All participants displayed atypical outcomes throughout the study, including oropharyngeal dysphagia initially during hospitalization. All participants were discharged on oral feeds but some breastfeeding difficulties persisted. Variable but pervasive developmental delays were found among all participants at 6 and 12 months. This study emphasizes the need for consistent early intervention from the neonatal period onward, for all infants with moderate HIE. Future studies should use larger cohorts, longer follow-up, and correlational designs.

Discussing brain magnetic resonance imaging results for neonates with hypoxic-ischemic encephalopathy treated with hypothermia: A challenge for clinicians and parents

Context

Clinicians use brain magnetic resonance imaging (MRI) to discuss neurodevelopmental prognosis with parents of neonates with hypoxic-ischemic encephalopathy (HIE) treated with therapeutic hypothermia (TH).

Purpose

To investigate how clinicians and parents discuss these MRI results in the context of HIE and TH and how these discussions could be facilitated and more meaningful for parents.

Procedures

Mixed-methods surveys with open-ended and closed-ended questions were completed by two independent groups. (1) Clinicians responded to clinical vignettes of neonates with HIE treated with TH with various types of clinical features, evolution and extent of brain injury and questions about how they discuss brain MRI results in this context. (2) Parents of children with HIE treated with TH responded to questions about the discussion of MRI that they had while still in the neonatal intensive care unit and were asked to place it in perspective with the outcomes of their child when he/she reached at least 2 years of age. Open-ended responses were analyzed using a thematic analysis approach. Closed-ended responses are presented descriptively.

Results

Clinicians reported uncertainty, lack of confidence, and limitations when discussing brain MRI results in the context of HIE and TH. Brain MRI results were "usually" (53%) used in the prognostication discussion. When dealing with day-2 brain MRIs performed during TH, most clinicians (40%) assumed that the results of these early MRIs were only "sometimes" accurate and only used them "sometimes" (33%) to discuss prognosis; a majority of them (66%) would "always" repeat imaging at a later time-point to discuss prognosis. Parents also struggled with this uncertainty, but did not discuss limitations of MRI as often. Parents raised the importance of the setting where the discussion took place and the importance to inform them as quickly as possible. Clinicians identified strategies to improve these discussions, including interdisciplinary approach, formal training, and standardized approach to report brain MRI. Parents highlighted the importance of communication skills, the stress, the hope surrounding their situation, and the need to receive answers as soon as possible. The importance of showing the pictures or making representative drawing of the injury, but also highlighting the not-injured brain, was also highlighted by parents.

Conclusions

Discussing brain MRI results for neonates with HIE treated with TH are challenging tasks for clinicians and daunting moments for parents.

Ethical considerations in the care of encephalopathic neonates treated with therapeutic hypothermia

Engaging with ethical issues is central to the management of neonatal encephalopathy (NE). As treatment for these neonates evolves, new ethical issues will arise and many existing challenges will remain. We highlight three key ethical issues that arise in the care of neonates with NE treated with therapeutic hypothermia: facilitating shared decision making, understanding futility, and defining the boundaries between standard of care and research. Awareness of these issues will help clinicians counsel families in light of evolving treatments and outcomes.

A systematic concept analysis of 'technology dependent': challenging the terminology

There are an increasing number of children who are dependent on medical technology to sustain their lives. Although significant research on this issue is taking place, the terminology used is variable and the concept of technology dependence is ill-defined. A systematic concept analysis was conducted examining the attributes, antecedents, and consequences of the concept of technology dependent, as portrayed in the literature. We found that this concept refers to a wide range of clinical technology to support biological functioning across a dependency continuum, for a range of clinical conditions. It is commonly initiated within a complex biopsychosocial context and has wide ranging sequelae for the child and family, and health and social care delivery.Conclusion: The term technology dependent is increasingly redundant. It objectifies a heterogenous group of children who are assisted by a myriad of technology and who adapt to, and function with, this assistance in numerous ways. What is Known: • There are an increasing number of children who require medical technology to sustain their life, commonly referred to as technology dependent. This concept analysis critically analyses the relevance of the term technology dependent which is in use for over 30 years. What is New: • Technology dependency refers to a wide range of clinical technology to support biological functioning across a dependency continuum, for a range of clinical conditions. It is commonly initiated within a complex biopsychosocial context and has wide-ranging sequelae for the child and family, and health and social care delivery. • The paper shows that the term technology dependent is generally portrayed in the literature in a problem-focused manner. • This term is increasingly redundant and does not serve the heterogenous group of children who are assisted by a myriad of technology and who adapt to, and function with, this assistance in numerous ways. More appropriate child-centred terminology will be determined within the TechChild project.

HBO Promotes the Differentiation of Neural Stem Cells via Interactions Between the Wnt3/β-Catenin and BMP2 Signaling Pathways

Hyperbaric oxygen (HBO) therapy may promote neurological recovery from hypoxic-ischemic encephalopathy (HIE). However, the therapeutic effects of HBO and its associated mechanisms remain unknown. The canonical Wnt/β-catenin signaling pathways and bone morphogenetic protein (BMP) play important roles in mammalian nervous system development. The present study examined whether HBO stimulates the differentiation of neural stem cells (NSCs) and its effect on Wnt3/β-catenin and BMP2 signaling pathways. We showed HBO treatment (2 ATA, 60 min) promoted differentiation of NSCs into neurons and oligodendrocytes in vitro. In addition, rat hypoxic-ischemic brain damage (HIBD) tissue extracts also promoted the differentiation of NSCs into neurons and oligodendrocytes, with the advantage of reducing the number of astrocytes. These effects were most pronounced when these two were combined together. In addition, the expression of Wnt3a, BMP2, and β-catenin nuclear proteins were increased after HBO treatment. However, blockade of Wnt/β-catenin or BMP signaling inhibited NSC differentiation and reduced the expression of Wnt3a, BMP2, and β-catenin nuclear proteins. In conclusion, HBO promotes differentiation of NSCs into neurons and oligodendrocytes and reduced the number of astrocytes in vitro possibly through regulation of Wnt3/β-catenin and BMP2 signaling pathways. HBO may serve as a potential therapeutic strategy for treating HIE.

A journey through follow-up for neurodevelopmentally at-risk infants-A qualitative study on views of parents and professionals in Liverpool

BACKGROUND

With improving neonatal intensive care, more preterm babies or those with hypoxic-ischaemic encephalopathy are surviving the newborn period. These babies are at high risk of neurodevelopmental delay. No studies to date have looked at the views of parents and professionals in relation to the processes of follow-up for these infants.

METHODS

We conducted a qualitative study in order to understand the views of parents of preterm babies or those with hypoxic-ischaemic encephalopathy as well as the views of professionals who manage and support these families. Parents were recruited through general neonatal follow-up clinics, neonatal nurse liaison services and community child health clinics and professionals through the neonatal unit and neurodevelopmental paediatrics services. We conducted in-depth interviews using an open-ended topic guide, which were audio recorded, transcribed and coded. We conducted a thematic content analysis where themes were inductively highlighted and grouped by consensus in order to conclude on major themes and subthemes.

RESULTS

Three major themes were identified for parents and professionals. These were the following: (a) What is the future, (b) What is the journey and (c) Who can help me? Parents wanted better information earlier about the prognosis and diagnoses through face to face, honest consultations with follow-up information available on the Internet. The most important requirements for follow-up clinics were honesty, reassurance, consistent pathways of follow-up and the need for a lead professional in the process. Alongside the follow-up process, there was a need for support groups and psychological support CONCLUSIONS: This study highlights the desire by parents for early information on the likely long-term outlook for their babies but the need to ensure that the information and support, which is given, is provided appropriately and with consideration in order to provide the best care of the whole family.

The complexity of physicians' understanding and management of prognostic uncertainty in neonatal hypoxic-ischemic encephalopathy

OBJECTIVE

Prognosis of Hypoxic-Ischemic Encephalopathy (HIE) remains challenging and uncertain. This paper investigates how physicians understand and address the ethical challenges of prognostic uncertainty in the case of neonatal HIE, contextualized within the social science literature.

STUDY DESIGN

Semi-structured interviews were conducted with 12 Canadian neurologists and neonatologists, addressing their perspectives and clinical experiences concerning neonatal HIE prognostication. Interviews were analyzed using thematic content analysis.

RESULTS

Participants unanimously recognized uncertainty in their prognostication. They identified several sources contributing to uncertainty in HIE prognostication, including etiology and underlying pathophysiologic mechanisms, statistical limitations, variable clinical data, the dynamic process of neurodevelopment, or the impact of hypothermia treatment. Unlike in some other literature, some physicians in this study talked about ways to render uncertainty explicit rather than hide it.

CONCLUSION

Results from this study support the call for recognition of the ubiquitous uncertainty surrounding this act in medical education and training.

Parent, patient and clinician perceptions of outcomes during and following neonatal care: a systematic review of qualitative research

OBJECTIVE

Multiple outcomes can be measured in infants that receive neonatal care. It is unknown whether outcomes of importance to parents and patients differ from those of health professionals. Our objective was to systematically map neonatal care outcomes discussed in qualitative research by patients, parents and healthcare professionals and test whether the frequency with which outcomes are discussed differs between groups.

DESIGN

Systematic review of qualitative literature. The following databases were searched: Medline, CINAHL, EMBASE, PsycINFO and ASSIA from 1997 to 2017. Publications describing qualitative data relating to neonatal care outcomes, reported by former patients, parents or healthcare professionals, were included. Narrative text was analysed and outcomes grouped thematically by organ system. Permutation testing was applied to assess an association between the outcomes identified and stakeholder group.

RESULTS

Sixty-two papers containing the views of over 4100 stakeholders were identified; 146 discrete outcomes were discussed; 58 outcomes related to organ systems and 88 to other more global domains. Permutation testing provides evidence that parents, former patients and health professionals reported outcomes with different frequencies (p=0.037).

CONCLUSIONS

Parents, patients and health professionals focus on different outcomes when discussing their experience of neonatal care. A wide range of neonatal care outcomes are reported in qualitative research; many are global outcomes relating to the overall status of the infant. The views of former patients and parents should be taken into consideration when designing research; the development of a core outcomes set for neonatal research will facilitate this.
