Just choice: a Danielsian analysis of the aims and scope of prenatal screening for fetal abnormalities

Mapping parents' journey following prenatal diagnosis of CHD: a qualitative study

OBJECTIVE

To better understand parents' accounts of their prenatal and postnatal experience after prenatal diagnosis of CHD - particularly emotional processing and coping mechanisms - to identify strategies to improve support.

METHODS

This single-centre, longitudinal qualitative study included pregnant mothers and their support persons seen in Fetal Cardiology Clinic at Vanderbilt Children's Hospital from May through August 2019 for probable complex CHD. Twenty-seven individuals from 17 families participated in 62 phone interviews during pregnancy and postpartum: 27 conducted after the initial prenatal cardiology consultation, 15 after a follow-up prenatal visit, and 20 after birth. Applied thematic analysis approach was used to code and analyse transcribed interviews. Coding and codebook revisions occurred iteratively; intercoder reliability was >80%.

RESULTS

Patients included mothers (16 [59%]), fathers (8 [30%]), and other support persons (3 [11%]). Initial fetal diagnoses included a range of moderate to severe CHD. Prenatally, parents sought to maintain hope while understanding the diagnosis; planning for the future rather than focusing on day-to-day was more common if prognoses were better. Postnatally, with confirmation of prenatal diagnoses, parents' sense of control expanded, and they desired more active engagement in clinical decision making.

CONCLUSIONS

To enhance effective communication and support, understanding how parents conceptualise hope in relation to diagnosis and how that may evolve over time is critical. Expectant parents whose child has a significant risk of mortality may demonstrate hope by focusing on positivity. As prognostic uncertainty diminishes postpartum, the parental role on the team may shift, requiring clinicians to provide different support.

Ethics experts and fetal patients: a proposal for modesty

Background

Ethics consultation is recognized as an opportunity to share responsibility for difficult decisions in prenatal medicine, where moral intuitions are often unable to lead to a settled decision. It remains unclear, however, if the general standards of ethics consultation are applicable to the very particular setting of pregnancy.

Main text

We sought to analyze the special nature of disagreements, conflicts and value uncertainties in prenatal medicine as well as the ways in which an ethics consultation service (ECS) could possibly respond to them and illustrated our results with a case example. Ethics facilitation and conflict mediation, currently, have no broadly consented normative framework encompassing prenatal diagnosis and therapy as well as reproductive choice to draw on. Even so, they can still be helpful instruments for ethically challenging decision-making in prenatal medicine provided two additional rules are respected: For the time being, ECSs should (a) refrain from issuing content-heavy recommendations in prenatal medicine and (b) should not initiate conflict mediations that would involve the pregnant woman or couple as a conflict party.

Conclusion

It seems to be vital that ethics consultants as well as health care professionals acknowledge the current limitations and pitfalls of ethics consultation in prenatal medicine and together engage in the advancement of standards for this particularly complex setting.

The fetus in the age of the genome

Due to a number of recent achievements, the field of prenatal medicine is now on the verge of a profound transformation into prenatal genomic medicine. This transformation is expected to not only substantially expand the spectrum of prenatal diagnostic and screening possibilities, but finally also to advance fetal care and the prenatal management of certain fetal diseases and malformations. It will come along with new and profound challenges for the normative framework and clinical care pathways in prenatal (and reproductive) medicine. To adequately address the potential ethically challenging aspects without discarding the obvious benefits, several agents are required to engage in different debates. The permissibility of the sequencing of the whole fetal exome or genome will have to be examined from a philosophical and legal point of view, in particular with regard to conflicts with potential rights of future children. A second requirement is a societal debate on the question of priority setting and justice in relation to prenatal genomic testing. Third, a professional-ethical debate and positioning on the goal of prenatal genomic testing and a consequential re-structuring of clinical care pathways seems to be important. In all these efforts, it might be helpful to envisage the unborn rather not as a fetus, not as a separate moral subject and a second "patient", but in its unique physical connection with the pregnant woman, and to accept the moral quandaries implicitly given in this situation.

Die Rechte zukünftiger Kinder im Kontext pränataler Diagnostik

Das Gendiagnostikgesetz (GenDG) verbietet seit 2010 die pränatale Diagnostik spätmanifestierender Erkrankungen (§ 15(2) GenDG). In seiner Begründung bezog sich der Gesetzgeber in Analogie zu internationalen Empfehlungen für den pädiatrischen Bereich vor allem auf das Recht des heranwachsenden Kindes bzw. des späteren Erwachsenen auf Nichtwissen. Mit diesem gesetzlichen Verbot hat Deutschland einen viel diskutierten Sonderweg in der Regulierung genetischer Pränataldiagnostik eingeschlagen. Seither jedoch hat sich nicht nur die Perspektive auf prädiktive Testungen im Kindesalter verändert. In zunehmendem Maße generieren auf das gesamte Genom abzielende Diagnostikangebote auch andere vorgeburtlich genetische Informationen, die – in ähnlicher Weise wie diejenigen zu spätmanifestierenden Erkrankungen eine potenzielle Gefahr für das Recht auf Nichtwissen der späteren Person darstellen. Es soll daher im Rahmen dieses Beitrages überprüft werden, inwiefern das deutsche Diagnostikverbot und dessen Bezug auf das Recht auf Nichtwissen des späteren Kindes eine tragfähige Basis zur Regulierung gendiagnostischer Untersuchungen in der Pränatalmedizin insgesamt darstellt bzw. zukünftig darstellen kann.

Untersucht wird der Argumentationsgang des Diagnostikverbotes im Hinblick auf spätmanifestierende Erkrankungen vor dem Hintergrund der Entwicklungen in der prädiktiven (genomischen) Diagnostik. Eine Analyse des normativen Begründungsrahmens zeigt, dass nach wie vor deutlicher Klärungsbedarf hinsichtlich der philosophisch-ethischen Fundierung wie auch hinsichtlich der Interpretation eines Rechts auf Nichtwissen eines (zukünftigen) Kindes im Kontext von genetischer Diagnostik besteht. Darüber hinaus müssen auch Interessen des (zukünftigen) Kindes an eventuell möglich werdender pränataler Behandlung oder Prävention von Erkrankungen in die Abwägung miteinbezogen werden.

Um zukünftigen Herausforderungen genomischer Pränataldiagnostik und -therapie begegnen zu können, müsste dringend geklärt werden, inwiefern Rechte zukünftiger Personen tatsächlich in der speziellen Situation der Schwangerschaft relevant sein können und mit welchen Pflichten diese für den Gesetzgeber, aber insbesondere auch für zukünftige Eltern und Ärzte einhergehen. Der Menschenrechtsdiskurs könnte hierfür eine tragfähige Basis und hilfreiche Strategien liefern.

The ethics of preconception expanded carrier screening in patients seeking assisted reproduction

Expanded carrier screening (ECS) entails a screening offer for carrier status for multiple recessive disorders simultaneously and allows testing of couples or individuals regardless of ancestry or geographic origin. Although universal ECS—referring to a screening offer for the general population—has generated considerable ethical debate, little attention has been given to the ethics of preconception ECS for patients applying for assisted reproduction using their own gametes. There are several reasons why it is time for a systematic reflection on this practice. Firstly, various European fertility clinics already offer preconception ECS on a routine basis, and others are considering such a screening offer. Professionals involved in assisted reproduction have indicated a need for ethical guidance for ECS. Secondly, it is expected that patients seeking assisted reproduction will be particularly interested in preconception ECS, as they are already undertaking the physical, emotional and economic burdens of such reproduction. Thirdly, an offer of preconception ECS to patients seeking assisted reproduction raises particular ethical questions that do not arise in the context of universal ECS: the professional’s involvement in the conception implies that both parental and professional responsibilities should be taken into account. This paper reflects on and provides ethical guidance for a responsible implementation of preconception ECS to patients seeking assisted reproduction using their own gametes by assessing the proportionality of such a screening offer: do the possible benefits clearly outweigh the possible harms and disadvantages? If so, for what kinds of disorders and under what conditions?

Why public funding for non-invasive prenatal testing (NIPT) might still be wrong: a response to Bunnik and colleagues

Bunnik and colleagues argued that financial barriers do not promote informed decision-making prior to prenatal screening and raise justice concerns. If public funding is provided, however, it would seem to be important to clarify its intentions and avoid any unwarranted appearance of a medical utility of the testing.

Uncertainty of Prenatally Diagnosed Congenital Heart Disease: A Qualitative Study

IMPORTANCE

Parents who receive a prenatal diagnosis of congenital heart disease may experience more short- and long-term stress than those who receive a postnatal diagnosis. To identify potential interventions to ameliorate that stress, the longitudinal emotional experience of parents must first be understood.

OBJECTIVE

To better understand parents' accounts of their own prenatal experience, particularly aspects they found to be stressful or challenging, and to identify strategies to improve support.

DESIGN, SETTING, AND PARTICIPANTS

This qualitative study included analysis of transcripts of audio recorded telephone interviews with pregnant mothers and their support persons, as applicable, who were referred to and seen at the Fetal Cardiology Clinic at Vanderbilt Children's Hospital from May 2019 to August 2019 with an initial likely diagnosis of complex congenital heart disease at any gestational age. Data analysis was conducted from August 2019 to November 2019.

MAIN OUTCOMES AND MEASURES

An applied thematic analysis approach was used to code and analyze professionally transcribed interviews. Coding and codebook revisions occurred iteratively; intercoder reliability was assessed and confirmed routinely. One author coded all transcripts; a second author independently reviewed one-fifth of the transcripts at fixed intervals to ensure that interrater reliability remained greater than 80%.

RESULTS

Twenty-seven individuals from 17 families participated in 42 phone interviews during pregnancy, 27 conducted at the first time point after the initial prenatal cardiology consultation and 15 at the second time point after a follow-up prenatal cardiology visit. Most interviewees were mothers (16 interviewees [59%]; median [interquartile range] age, 30.0 [27.3-34.8] years) or fathers (8 interviewees [30%)], with a few support individuals (3 interviewees [11%]) (median [interquartile range] age of family member or support individual, 30.0 [26.0-42.0] years). Initial fetal diagnoses included a range of severe congenital heart disease. Uncertainty was identified as a pervasive central theme and was related both to concrete questions on scheduling, logistics, or next steps, and long-term unknown variables concerning the definitiveness of the diagnosis or overall prognosis. Practitioners helped families through their framing of uncertainty at various time points including before, during, and after the clinic visit.

CONCLUSIONS AND RELEVANCE

Families walk an uncertain path following a fetal diagnosis of severe congenital heart disease. The challenges faced by the cardiologists caring for them overlap in many ways with those experienced by pediatric palliative care practitioners. Potential future interventions to improve parental support were identified in the areas of expectation setting before the referral visit, communication in clinic, and identity formation after the new diagnosis.

A Capabilities Approach to Prenatal Screening for Fetal Abnormalities

International guidelines recommend that prenatal screening for fetal abnormalities should only be offered within a non-directive framework aimed at enabling women in making meaningful reproductive choices. Whilst this position is widely endorsed, developments in cell-free fetal DNA based Non-Invasive Prenatal Testing are now raising questions about its continued suitability for guiding screening policy and practice. This issue is most apparent within debates on the scope of the screening offer. Implied by the aim of enabling meaningful reproductive choices is the idea that screening services should support women in accessing prenatal tests that best enable them to realize the types of reproductive choice that they find important. However, beyond whatever options meet the quality standards required for facilitating an informed decision, the remaining criteria of facilitating autonomous choice is strictly non-directive. As a result, policy makers receive little indication prior to consultation with each individual woman, about what conditions should be prioritized during the offer of screening. In this paper we try to address this issue by using the capabilities approach to further specify the non-directive aim of enabling meaningful reproductive choice. The resulting framework is then used to assess the relative importance of offering prenatal screening where concerning different types of genetic condition. We conclude that greater priority may be ascribed to offering prenatal screening for conditions that more significantly diminish a woman's central capabilities. It follows that serious congenital and earlier-onset conditions are more likely to fulfill these criteria.
