Protect us from ourselves: Balancing the parental instinct of saving

Ethical reflections on organizing the first human trial of artificial womb technologies

OBJECTIVE

To investigate how to protect participants in the artificial womb technology (AWT) human trials.

METHOD

We compared randomized controlled trials and single arm trials to understand which trial design best balances the interests of science and participants. We also compared AWT trials with comparable settings to understand how to protect participants.

RESULTS

Randomized trials might fail in reaching a sizeable sample, which could pointlessly expose participants to risks. Furthermore, parents who choose to participate in the trial might expect to receive AWT. Failed expectations might distress parents and hinder the therapeutic relationship. The trial is divided into two steps. First, delivery into AWT involves two participants: the mother and the fetus. As AWT requires a C-section, the procedure cannot be carried out without the mother's consent regardless of fetal benefit. Treatment in AWT, involves one participant: the infant. As for any other invasive intervention, the AWT trial should be suspended if harmful.

CONCLUSIONS

A single arm trial could prevent some of the methodological and ethical challenges of the randomized trials. Moreover, better decisional tools should be developed to help parents decide whether to participate in the AWT trial. For example, using visual aids or showing the AWT.

A scoping review of parental values during prenatal decisions about treatment options after extremely premature birth

AIM

To describe what is known in the literature about parental perspectives in making prenatal decisions regarding treatment after birth at the limit of viability, as a better understanding of parental values can help professionals support parents as they decide.

METHODS

PubMed, Cochrane, Embase, CINAHL, PsycINFO and Web of Science were searched to identify relevant literature from 1 January 2010 to 22 April 2022 on parental decision making. Data were extracted from selected studies and organised into themes. The final themes were formed through collaboration with the parents of a premature infant born at 24 weeks.

RESULTS

Of the 15,159 papers examined, 17 were included. Parental perspectives were described in terms of long-term outcomes for the infant, survival, protection against the burden of neonatal treatment, long-term impact on the family, religion and spiritual beliefs, to do everything possible, hope, sense of responsibility, wanting the best, doing what is right, giving a chance and the influence of experience.

CONCLUSION

The extracted parental perspectives show the complexity of these decisions. Some perspectives were clear, but others were multi-interpretable. Increasing the understanding of common parental perspectives can help improve shared prenatal decisions and lead to further improvement and personalisation of the process.

Decision-Making for Extremely Preterm Infants: A Qualitative Systematic Review

OBJECTIVE

To synthesize and describe important elements of decision-making during antenatal consultation for threatened preterm delivery at the margin of gestational viability.

STUDY DESIGN

Data sources including PubMed, EMBASE, Web of Science, and CINAHL Plus were searched. We included all qualitative literature published on decision-making from 1990 to July 2021. Two authors independently screened and evaluated each study using the Critical Appraisal Skills Programme checklist; studies reaching moderate and high quality were included. We developed an extraction tool to collect and categorize data from each qualitative article, then used thematic analysis to analyze and describe the findings.

RESULTS

Twenty-five articles incorporating the views of 504 providers and 352 parents were included for final review. Thematic analysis revealed 4 main themes describing the experience of health care providers and parents participating in decision-making: factors that influence decision-making, information sharing, building a partnership, and making the decision. Parents and providers were not always in agreement upon which elements were most essential to the process of decision-making. Articles published in languages other than English were excluded.

CONCLUSIONS

Qualitative literature highlighting key factors which are important during antenatal counseling can inform and guide providers through the process of shared decision-making. Communicating clear, honest, and balanced information; avoiding artificially dichotomized options; and focusing on partnership building with families will help providers use the antenatal consultation to reach personalized decisions for each infant.

Postponed Withholding: Balanced Decision-Making at the Margins of Viability

Advances in neonatology have led to improved survival for periviable infants. Immaturity still carries a high risk of short- and long-term harms, and uncertainty turns provision of life support into an ethical dilemma. Shared decision-making with parents has gained ground. However, the need to start immediate life support and the ensuing difficulty of withdrawing treatment stands in tension with the possibility of a fair decision-making process. Both the parental "instinct of saving" and "withdrawal resistance" involved can preclude shared decision-making. To help health care personnel and empower parents, we propose a novel approach labeled "postponed withholding." In the absence of a prenatal advance directive, life support is started at birth, followed by planned redirection to palliative care after one week, unless parents, after a thorough counseling process, actively ask for continued life support. Despite the emotional challenges, this approach can facilitate ethically balanced decision-making processes in the gray zone.
