Experiences of receiving an increased chance of sex chromosome aneuploidy result from non-invasive prenatal testing in Australia: "A more complicated scenario than what I had ever realized". J Genet Couns 2023; 32:213-223. [PMID: 36114608 DOI: 10.1002/jgc4.1635] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2022] [Revised: 08/23/2022] [Accepted: 08/24/2022] [Indexed: 11/11/2022]
Abstract
Many non-invasive prenatal testing (NIPT) platforms screen for sex chromosome aneuploidy (SCA) and SCA analysis is generally included in Australia where NIPT is available as a self-funded test. Little is known about the experience of receiving an NIPT result indicating an increased chance of SCA. This study aimed to explore the experiences of people who received this result and their perspectives on the information, care, and support they received from healthcare practitioners (HCPs). Semi-structured interviews were conducted with people who received an NIPT result indicating an increased chance of SCA and continued their pregnancy. Most participants only had contact with a genetic counselor after receiving their result. Transcribed data were analyzed using rigorous thematic analysis to identify important patterns and themes. Participants (18 women, 2 male partners) described embarking on NIPT, primarily based on advice from their HCP and without much consideration. Consequently, participants expressed feeling unprepared for the unanticipated complexity of their NIPT result and were faced with making a time-sensitive decision about a condition they had not previously considered. While more pre-test information was desired, timely access to genetic counseling post-test assisted with adjustment to the result. These findings suggest that routinization of NIPT may be compromising informed decision-making, resulting in unpreparedness for an increased chance result. Given the increasing uptake and expanding scope of NIPT, resources should be dedicated to educating HCPs offering NIPT and ensuring timely access to genetic counseling post-result. With appropriate funding, genetics services may be able to play a central role in offering information and support to both people who undertake NIPT and their HCPs ordering the testing. Implementing a publicly funded screening program in Australia could assist with standardizing prenatal screening care pathways and consequently better access to appropriate resources.

Prenat Diagn 2023; 43:62-71. [PMID: 36461628 DOI: 10.1002/pd.6278] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2022] [Revised: 10/24/2022] [Accepted: 11/27/2022] [Indexed: 12/04/2022]
Abstract
In recent years, as the implementation and use of Non-Invasive Prenatal Testing (NIPT) have increased, the cost of the test has been decreasing. The cost of NIPT is expected to fall further in the upcoming years. As a result of the decreasing cost of NIPT, many jurisdictions may change their prenatal screening policies toward abandoning serum-based screening and instead, implement and support NIPT as the first-tier screening for all women. There are several concerns in replacing first-trimester screening with NIPT. In this scoping review, we aimed to map the existing knowledge about possible issues in the systematic implementation of NIPT as the primary method of first-tier screening and to assess if any jurisdiction has altered its policy and discontinued serum-based prenatal screening in exchange for NIPT. The Medline database (Ovid) and Google Scholar was searched and all the studies discussing, investigating, or reporting on the systematic implementation of NIPT as the primary method of first-tier screening were included. All the studies went through a two-stage screening process and included full-text articles were reviewed. We did not find any articles indicating a country or region that replaced traditional prenatal screening by NIPT. The included articles were charted, and the data about the possible issues in the systematic implementation of NIPT as the primary method of first-tier screening are summarized narratively and presented in tables in four categories. The findings of this scoping review may be informative for stakeholders and policymakers regarding recent changes in NIPT implementation policies around the world and may aid with developing policy for NIPT implementation with a broader perspective.

[PMID: 36013258 PMCID: PMC9409855 DOI: 10.3390/jpm12081310] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2022] [Revised: 08/02/2022] [Accepted: 08/10/2022] [Indexed: 11/22/2022] Open
Abstract
There is significant heterogeneity in the outcomes assessed across studies of reproductive genetic carrier screening (RGCS). Only a small number of studies have measured patient-reported outcomes or included patients in the selection of outcomes that are meaningful to them. This study was a cross-sectional, qualitative study of 15 patient participants conducted to inform a core outcome set. A core outcome set is an approach to facilitate standardisation in outcome reporting, allowing direct comparison of outcomes across studies to enhance understanding of impacts and potential harms. The aim of this study was to incorporate the patient perspective in the development of a core outcome set by eliciting a detailed understanding of outcomes of importance to patients. Data were collected via online, semi-structured interviews using a novel method informed by co-design and the nominal group technique. Data were analysed using reflexive thematic analysis. Outcomes elicited from patient stakeholder interviews highlighted several under-explored areas for future research. This includes the role of grief and loss in increased risk couples, the role of empowerment in conceptualising the utility of RGCS, the impact of societal context and barriers that contribute to negative experiences, and the role of genetic counselling in ensuring that information needs are met and informed choice facilitated as RGCS becomes increasingly routine. Future research should focus on incorporating outcomes that accurately reflect patient needs and experience.

Abstract
BackgroundThe main purpose of this study was to describe the latent structure of pregnancy perception by investigating the role of risks and medical examinations in pregnancy perception across the sexes and pregnancy status.MethodsStudy 1 developed a questionnaire based on the responses of 29 young adults on their perception of pregnancy. Study 2 consisted of distributing the questionnaire among 290 participants (mean age 29.3; standard deviation = 7.5).ResultsThe statistical clustering analysis revealed three major clusters of pregnancy perceptions: “evaluative,” “physio-medical,” and “future considerations,” each of them encompassing several meaningful sub-clusters. This structure of pregnancy perceptions supports Beck and Beck-Gernsheim’s modernization approach. Negative emotions toward pregnancy were related to social cognitions, whereas thoughts about risks were included in the medical sub-cluster. After reliability analyses, comparisons of scale scores revealed that women experienced more positive emotions, thought more about physical symptoms and about future issues compared to men (evolutionary explanation was offered).ConclusionPregnant participants felt less ambivalence toward pregnancy, thought more about risks and medical examinations and less about parents’ duties than non-pregnant participants.

Nakou P. Is routine prenatal screening and testing fundamentally incompatible with a commitment to reproductive choice? Learning from the historical context. MEDICINE, HEALTH CARE, AND PHILOSOPHY 2021; 24:73-83.

Abstract
An enduring ethical dispute accompanies prenatal screening and testing (PST) technologies. This ethical debate focuses on notions of reproductive choice. On one side of the dispute are those who have supported PST as a way to empower women's reproductive choice, while on the other side are those who argue that PST, particularly when made a routine part of prenatal care, limits deliberate choice. Empirical research does not resolve this ethical debate with evidence both of women for whom PST enhances their choices but also persistent evidence of recurrent problems between PST and women's autonomous decision-making. While there have been attempts to remove challenges to reproductive choice, it has been argued that these challenges cannot be removed entirely. In this paper I provide a historical review of PST technologies' development and in doing so provide a detailed insight into the root causes of this tension between the opposing sides of this debate. This historical account provides evidence that those who championed the early use of these technologies did so in order to achieve a number of wholly different goals other than women's choice and empowerment. These different aims focus on scientific discovery and eugenic goals and, I argue, are irreconcilable with women's choice and empowerment. It thus may not be surprising that the resulting practice of PST continues to resist compatibility with women's choice and empowerment. Ultimately, by understanding the historical foundations of PST we can more effectively assess how to reconcile women's reproductive autonomy with routine prenatal screening.

Abstract
New technologies such as non-invasive prenatal testing (NIPT), capable of analyzing cell-free fetal DNA in the maternal bloodstream, have become increasingly widespread and available, which has in turn led to ethical and policy challenges that need addressing. NIPT is not yet a diagnostic tool, but can still provide information about fetal genetic characteristics (including sex) very early in pregnancy, and there is no denying that it offers valuable opportunities for pregnant women, particularly those at high risk of having a child with severe genetic disorders or seeking an alternative to invasive prenatal testing. Nonetheless, the ethical, legal and social implications (ELSI) include multiple aspects of informed decision-making, which can entail risks for the individual right to procreative autonomy, in addition to the potential threats posed by sex-selective termination of pregnancy (in light of the information about fetal sex within the first trimester), and the stigmatization and discrimination of disabled individuals. After taking such daunting challenges into account and addressing NIPT-related medicolegal complexities, the review's authors highlight the need for an ethically and legally sustainable framework for the implementation of NIPT, which seems poised to become a diagnostic tool, as its scope is likely to broaden in the near future.

Abstract
Background Non-invasive prenatal testing (NIPT) allows women to access genetic information about their fetuses without the physical risk inherent to prior testing methods. The advent of NIPT technology has led to concerns regarding the quality and process of informed consent, as a view of NIPT as “routine” could impair women’s considered approach when choosing to undergo testing. Prior studies evaluating NIPT decision-making have focused on the clinical encounter as the primary environment for acquisition of biomedical information and decision formation. While important, this conceptualization fails to consider how additional sources of knowledge, including embodied and empathetic experiential knowledge, shape perceptions of risk and the societal use of NIPT. Methods In order to address this issue, qualitative, semi-structured interviews with 25 women who had been offered NIPT were performed. Participants came from a well-resourced, rural setting near a major academic medical center in the US. Women were categorized by NIPT use/non-use as well as whether their described decision-making process was perceived as making a significant decision requiring contemplation (“significant”) versus a rapid or immediate decision (“routinized”). A constructivist general inductive approach was used to explore themes in the data, develop a framework of NIPT decision-making, and compare the perceptions of women with differential decision-making processes and outcomes. Results A framework for decision-making regarding NIPT was developed based on three emergent factors: perceptions of the societal use of NIPT, expected emotional impact of genetic information, and perceived utility of genetic information. Analysis revealed that perceptions of widespread use of NIPT, pervasive societal narratives of NIPT use as “forward-thinking,” and a perception of information as anxiety-relieving contributed to routinized uptake of NIPT. In contrast, women who displayed a lack of routinization expressed fewer stereotypes regarding the audience for NIPT and relied on communication with their social networks to consider how they might use the information provided by NIPT. Conclusions The findings of this study reveal the societal narratives and perceptions that shape differential decision-making regarding NIPT in the U.S. context. Understanding and addressing these perceptions that influence NIPT decision-making, especially routinized uptake of NIPT, is important as the use and scope of this technology increases.

Abstract
OBJECTIVE Japan is the only country in the world that allows abortions due to economic reasons but illegalise them due to foetal anomaly. The objective of this study was to explore the choice-making experiences for prenatal screening among Japanese women and their spouses in Austria. METHODS We conducted a qualitative study using semi-structured face-to-face interviews with Japanese women and their spouses in Austria. Data were analysed using thematic analysis. RESULTS Twenty-five participants (14 women and 11 men) took part in the interviews. Four themes were identified: 1) Knowledge, information and memory; 2) Communication and interactions with health professionals; 3) Reasons for choice; and 4) Emotional support. Participants had limited knowledge and experienced directive counselling. Women expressed negative emotions in the choice-making processes, did not perceive husbands as a source of support and lacked a person to consult. CONCLUSION There are common characteristics among East Asian population despite different context and differences found between our Japanese participants and women in other European countries. PRACTICE IMPLICATION Proactive interventions aimed at increasing knowledge that help women to develop their preferences and reflect on their values could be further promoted among women of all socio-cultural backgrounds in Austria.

Abstract
OBJECTIVE The introduction of non-invasive prenatal testing (NIPT) for Down syndrome (DS) has sparked social and ethical debates. To date, in-depth exploration of the voices of Australian mothers of a child with DS about NIPT has been lacking. The purpose of this study was to investigate the perspectives of Australian mothers of a child with DS towards the increasing availability of NIPT. DESIGN AND SETTING Fifteen mothers of children with DS aged 8 months-39 years participated in-depth interviews, conducted online via the software Zoom™. An inductive thematic analysis of interview data explored mothers' perceptions of NIPT. FINDINGS Mothers perspectives were nuanced and personal to each woman's circumstance. All mothers highlighted the inevitable association between testing and termination, the importance of autonomy and respecting [m]others' choices to test and to terminate, and that appropriate supports must be provided to ensure informed decision-making. These perspectives existed within an overarching theme of NIPT reflecting and reinforcing societal attitudes towards disability. CONCLUSION Mothers of a child with DS viewed informed decision-making as crucial both prior to undertaking NIPT and following a positive test result. This study adds a unique Australian perspective to the necessary ongoing social and ethical debate.

Abstract
OBJECTIVE This study sought to assess Canadian pregnant women's and their partners' preferences for information about non-invasive prenatal testing (NIPT). METHODS Pregnant women and their partners across Canada were surveyed as part of the Personalized Genomics for prenatal Aneuploidy Screening Using maternal blood (PEGASUS) study. RESULTS A total of 882 pregnant women and 395 partners participated. Women preferred being informed by a physician (77.2%). They preferred getting information ahead of time, except for information about resources for families with Down syndrome, which they preferred getting with test results. More than half thought that written consent is important (63.7%) and could decide whether to do NIPT on the day they received the information (54.9%). Women preferred to be informed of results by telephone (43.7%) or in person (28%), but they preferred in person if they were considered at high risk for Down syndrome on the basis of the results (76%). The partner was the person whose input was considered most important (62.6%). Partners' preferences were similar, except that partners tended to want information later (at the time of the test or with the results) and felt that their opinion was not considered as highly by health professionals. CONCLUSION Canadian women want information about NIPT early, in person, by a knowledgeable physician. Partners also want to be informed and involved in the decision-making process.

Abstract
Background Non‐invasive prenatal testing (NIPT) has been available in Australia on a user‐pays basis since 2012. Since its introduction, it has grown in popularity as a screening method for fetal aneuploidy and may become publicly funded. Aims To assess the motivations and experiences of women who have undergone NIPT in a user‐pays system in Australia. Materials and methods One thousand women who had undergone NIPT through the Victorian Clinical Genetics Services in Melbourne, Australia were contacted and asked to complete a mixed‐methods survey. The number of eligible responses received was 235. Quantitative data analysis was performed in STATA IC 15.1, and qualitative data were examined using content analysis. Results Women reported generally positive experiences with NIPT and 95% of respondents indicated they would undergo NIPT in a future pregnancy. Most respondents received a low‐risk result, with 2.2% receiving a high‐risk result. Respondents viewed NIPT favourably compared to invasive testing and cited reassurance as a key reason they sought it. However, a small minority of women reported negative experiences with the testing process. Women were also supportive of NIPT becoming publicly funded, with 93% of respondents indicating support. Pre‐ and post‐test counselling were identified as possible areas for improvement to ensure informed consent. Conclusion In support of the existing literature, these results indicate that Australian women generally report positive experiences with NIPT. As NIPT becomes more common, with possible integration into public healthcare, further qualitative research would be valuable to examine the motivations and experiences of women undergoing NIPT.

Facilitating informed choice about non-invasive prenatal testing (NIPT): a systematic review and qualitative meta-synthesis of women's experiences. BMC Pregnancy Childbirth 2019; 19:27. [PMID: 30642270 PMCID: PMC6332899 DOI: 10.1186/s12884-018-2168-4] [Citation(s) in RCA: 57] [Impact Index Per Article: 11.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2018] [Accepted: 12/28/2018] [Indexed: 01/09/2023] Open
Abstract
BACKGROUND Non-invasive prenatal testing (NIPT) can be used to accurately detect fetal chromosomal anomalies early in pregnancy by assessing cell-free fetal DNA present in maternal blood. The rapid diffusion of NIPT, as well as the ease and simplicity of the test raises concerns around informed decision-making and the potential for routinization. Introducing NIPT in a way that facilitates informed and autonomous decisions is imperative to the ethical application of this technology. We approach this imperative by systematically reviewing and synthesizing primary qualitative research on women's experiences with and preferences for informed decision-making around NIPT. METHODS We searched multiple bibliographic databases including Ovid MEDLINE, EBSCO Cumulative Index to Nursing & Allied Health Literature (CINAHL), and ISI Web of Science Social Sciences Citation Index (SSCI). Our review was guided by integrative qualitative meta-synthesis, and we used a staged coding process similar to that of grounded theory to conduct our analysis. RESULTS Thirty empirical primary qualitative research studies were eligible for inclusion. Women preferred to learn about NIPT from their clinicians, but they expressed dissatisfaction with the quality and quantity of information provided during counselling and often sought information from a variety of other sources. Women generally had a good understanding of test characteristics, and the factors of accuracy, physical risk, and test timing were the critical information elements that they used to make informed decisions around NIPT. Women often described NIPT as easy or just another blood test, highlighting threats to informed decision-making such as routinization or a pressure to test. CONCLUSIONS Women's unique circumstances modulate the information that they value and require most in the context of making an informed decision. Widened availability of trustworthy information about NIPT as well as careful attention to the facilitation of counselling may help facilitate informed decision-making.

Abstract
Background Canadian policies regarding the implementation and public coverage of non-invasive prenatal testing (NIPT) are heterogeneous and shifting, with NIPT being publicly covered for high-risk pregnancies in some provinces, but not others. Such a diverse and evolving policy landscape provides fertile ground for examining the preferences of pregnant women, their partners, and health professionals regarding the implementation and coverage of NIPT by the public healthcare system, as well as the factors influencing their preferences, which is what the present study does. Methods In this paper, we report the results of three-large scale Canadian surveys, in which 882 pregnant women, 395 partners of pregnant women, and 184 healthcare professionals participated. Results The paper focuses on preferences regarding how and when NIPT should be used, as well as the factors influencing these preferences, and how coverage for NIPT should be provided. These are correlated with respondents’ levels of knowledge about Down syndrome and testing technologies and with their stated intended use of NIPT results. Conclusion Salient is the marked difference between the preferences of prospective parents and those of healthcare professionals, which has potential implications for Canadian policy regarding NIPT implementation and insurance coverage.

Abstract
Difficult ethical issues arise for patients and professionals in medical genetics, and often relate to the patient's family or their social context. Tackling these issues requires sensitivity to nuances of communication and a commitment to clarity and consistency. It also benefits from an awareness of different approaches to ethical theory. Many of the ethical problems encountered in genetics relate to tensions between the wishes or interests of different people, sometimes even people who do not (yet) exist or exist as embryos, either in an established pregnancy or in vitro. Concern for the long-term welfare of a child or young person, or possible future children, or for other members of the family, may lead to tensions felt by the patient (client) in genetic counselling. Differences in perspective may also arise between the patient and professional when the latter recommends disclosure of information to relatives and the patient finds that too difficult, or when the professional considers the genetic testing of a child, sought by parents, to be inappropriate. The expectations of a patient's community may also lead to the differences in perspective between patient and counsellor. Recent developments of genetic technology permit genome-wide investigations. These have generated additional and more complex data that amplify and exacerbate some pre-existing ethical problems, including those presented by incidental (additional sought and secondary) findings and the recognition of variants currently of uncertain significance, so that reports of genomic investigations may often be provisional rather than definitive. Experience is being gained with these problems but substantial challenges are likely to persist in the long term.

Limits to the scope of non-invasive prenatal testing (NIPT): an analysis of the international ethical framework for prenatal screening and an interview study with Dutch professionals. BMC Pregnancy Childbirth 2018; 18:409. [PMID: 30340550 PMCID: PMC6194707 DOI: 10.1186/s12884-018-2050-4] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2017] [Accepted: 10/10/2018] [Indexed: 12/21/2022] Open
Abstract
Background The introduction of non-invasive prenatal testing (NIPT) for foetal aneuploidies is currently changing the field of prenatal screening in many countries. As it is non-invasive, safe and accurate, this technique allows for a broad implementation of first-trimester prenatal screening, which raises ethical issues, related, for instance, to informed choice and adverse societal consequences. This article offers an account of a leading international ethical framework for prenatal screening, examines how this framework is used by professionals working in the field of NIPT, and presents ethical guidance for the expansion of the scope of prenatal screening in practice. Methods A comparative analysis of authoritative documents is combined with 15 semi-structured interviews with professionals in the field of prenatal screening in the Netherlands. Data were recorded, transcribed verbatim and analysed using thematic analysis. Results The current ethical framework consists of four pillars: the aim of screening, the proportionality of the test, justice, and societal aspects. Respondents recognised and supported this framework in practice, but expressed some concerns. Professionals felt that pregnant women do not always make informed choices, while this is seen as central to reproductive autonomy (the aim of screening), and that pre-test counselling practices stand in need of improvement. Respondents believed that the benefits of NIPT, and of an expansion of its scope, outweigh the harms (proportionality), which are thought to be acceptable. They felt that the out-of-pocket financial contribution currently required by pregnant women constitutes a barrier to access to NIPT, which disproportionally affects those of a lower socioeconomic status (justice). Finally, professionals recognised but did not share concerns about a rising pressure to test or discrimination of disabled persons (societal aspects). Conclusions Four types of limits to the scope of NIPT are proposed: NIPT should generate only test outcomes that are relevant to reproductive decision-making, informed choice should be (made) possible through adequate pre-test counselling, the rights of future children should be respected, and equal access should be guaranteed. Although the focus of the interview study is on the Dutch healthcare setting, insights and conclusions can be applied internationally and to other healthcare systems.

Abstract
Background Cell-free fetal DNA sequencing based non-invasive prenatal testing (NIPT) for Down syndrome (DS) has become widely available. In Hong Kong, obstetric providers in the public sector refer women identified at high risk of having a child with Down syndrome to obstetric providers in the private sector for NIPT. Little is known about how the NIPT has been adopted in the public sector where DS screening is provided for free of charge. The study aimed to identify the factors influencing providers’ role enactment, such as consultation and referral, in the service provision of NIPT for DS in public and private healthcare sectors. Methods In-depth interviews were conducted with 20 obstetric providers offering NIPT in Hong Kong. Thematic narrative analysis was used to identify (i) the factors considered by participants when referring women for NIPT for Down syndrome in public and private healthcare sectors and (ii) their perceptions of the need to integrate NIPT into the current public antenatal service. Results Participants raised concerns about the lack of transparent referral guideline between public and private sectors for NIPT. Public obstetric providers reported little obligation to provide women with much information about risks and benefits of NIPT as it was not provided by public sectors. Some private providers assumed that women referred from the public sector had already received sufficient information about NIPT. The providers were also concerned about potential application of NIPT for further detection without regulation. Conclusions Although the providers had good knowledge of clinical advantages of NIPT over conventional screening, they were uncertain about how to introduce NIPT to women. Guidelines are necessary to enable better coordination of public and private sectors services to enable women to make informed choices about the uptake of NIPT.

Abstract
In the debate surrounding the introduction of non-invasive prenatal testing (NIPT) in prenatal screening programmes, the concept of routinisation is often used to refer to concerns and potential negative consequences of the test. A literature analysis shows that routinisation has many different meanings, which can be distinguished in three major versions of the concept. Each of these versions comprises several inter-related fears and concerns regarding prenatal screening and particularly regarding NIPT in three areas: (1) informed choice, (2) freedom to choose and (3) consequences for people with a disability. Three of the strongest arguments raised under the flag of routinisation are assessed for their validity: the threat that NIPT poses to informed choice, the potential increase in uptake of first-trimester prenatal screening and its consequences for social pressure to participate in screening or terminate affected pregnancies, and the negative consequences for disabled people. These routinisation arguments lack empirical or normative ground. However, the results of this analysis do not imply that no attention should be paid to possible problems surrounding the introduction of NIPT. At least two problems remain and should be addressed: there should be an ongoing debate about the requirements of informed choice, particularly related to an expanded scope of prenatal screening. Also, reproductive autonomy can only be achieved when expecting parents' options are variegated, real and valuable, so that they can continue to choose whether or not to screen or to terminate a pregnancy.

Abstract
OBJECTIVE Situational factors of prenatal screening have changed in recent decades. To explore the effect of a changing context on women's decision making, differences and similarities in the decision-making process of pregnant women regarding prenatal screening for fetal aneuploidy between two periods in time were studied. DESIGN A qualitative comparison was made between a dataset of 22 semi-structured interviews with pregnant women from 2003 and a newly collected dataset with 19 semi-structured interviews from 2016. FINDINGS Overall, women reported similar considerations in their decision-making process in 2003 and 2016, suggesting that decision making has not essentially changed. In 2016, women were still making a deliberate decision, however for some women costs and societal views as to what is acceptable did appear to impact the decision-making process. Moreover, new screening possibilities (e.g. improved test characteristics and including more conditions to be screened) seemed to impact the decision outcome. CONCLUSIONS Since most women based their decisions mainly on their personal values and personal experiences rather than on situational factors, the results suggest that the changing context with regard to prenatal screening had no major effect on women's decision making. It therefore seems unlikely that future changes in the field of prenatal screening will drastically change the decision-making process of pregnant women as long as informed and deliberate decision making is safeguarded.

Abstract
Background Non-Invasive Prenatal Testing (NIPT) is a technology which provides information about fetal genetic characteristics (including sex) very early in pregnancy by examining fetal DNA obtained from a sample of maternal blood. NIPT is a morally complex technology that has advanced quickly to market with a strong push from industry developers, leaving many areas of uncertainty still to be resolved, and creating a strong need for health policy that reflects women’s social and ethical values. We approach the need for ethical policy-making by studying the use of NIPT and emerging policy in the province of Ontario, Canada. Methods Using an adapted version of constructivist grounded theory, we conducted interviews with 38 women who have had personal experiences with NIPT. We used an iterative process of data collection and analysis and a staged coding strategy to conduct a descriptive analysis of ethics issues identified implicitly and explicitly by women who have been affected by this technology. Results The findings of this paper focus on current ethical issues for women seeking NIPT, including place in the prenatal pathway, health care provider counselling about the test, industry influence on the diffusion of NIPT, consequences of availability of test results. Other issues gain relevance in the context of future policy decisions regarding NIPT, including funding of NIPT and principles that may govern the expansion of the scope of NIPT. These findings are not an exhaustive list of all the potential ethical issues related to NIPT, but rather a representation of the issues which concern women who have personal experience with this test. Conclusions Women who have had personal experience with NIPT have concerns and priorities which sometimes contrast dramatically with the theoretical ethics literature. These findings suggest the importance of engaging patients in ethical deliberation about morally complex technologies, and point to the need for more deliberative patient engagement work in this area.

Abstract
Non-invasive prenatal testing (NIPT) using cell-free fetal DNA (cffDNA) from maternal blood has recently entered clinical practice in many countries, including Canada. This test can be performed early during pregnancy to detect Down syndrome and other conditions. While NIPT promises numerous benefits, it also has challenging ethical, legal and social implications (ELSI). This paper reviews concerns currently found in the literature on the ELSI of NIPT. We make four observations. First, NIPT seems to exacerbate some of the already existing concerns raised by other prenatal tests (amniocentesis and maternal serum screening) such as threats to women’s reproductive autonomy and the potential for discrimination and stigmatization of disabled individuals and their families. This may be due to the likely upcoming large scale implementation and routinization of NIPT. Second, the distinction between NIPT as a screening test (as it is currently recommended) and as a diagnostic test (potentially in the future), has certain implications for the ELSI discussion. Third, we observed a progressive shift in the literature from initially including mostly conceptual analysis to an increasing number of empirical studies. This demonstrates the contribution of empirical bioethics approaches as the technology is being implemented into clinical use. Finally, we noted an increasing interest in equity and justice concerns regarding access to NIPT as it becomes more widely implemented.

Abstract
Non-invasive prenatal testing (NIPT), based on analysis of cell-free foetal DNA, is rapidly becoming a preferred method to screen for chromosomal aneuploidy with the technology now available in over 90 countries. This review provides an up-to-date discussion of the key clinical, social and ethical implications associated with this revolutionary technology. Stakeholders are positive about a test that is highly accurate, safe, can be perfomed early in pregnancy, identifies affected pregnancies that might otherwise have been missed and reduces the need for invasive testing. Nevertheless, professional societies currently recommend it as an advanced screening test due to the low false positive rate (FPR). Despite the practical and psychological benefits, a number of concerns have been raised which warrant attention. These include the potential for routinisation of testing and subsequent impact on informed decision-making, an "easy" blood test inadvertently contributing to women feeling pressured to take the test, fears NIPT will lead to less tolerance and support for those living with Down syndrome and the heightened expectation of having "perfect babies". These issues can be addressed to some extent through clinician education, patient information and establishing national and international consensus in the development of comprehensive and regularly updated guidelines. As the number of conditions we are able to test for non-invasively expands it will be increasingly important to ensure pre-test counselling can be delivered effectively supported by knowledgeable healthcare professionals.

Abstract
OBJECTIVE To investigate women's decision to undergo non-invasive and/or invasive tests for prenatal diagnosis depending on the procedure-related risk and the risk of carrying a foetus with Down syndrome (DS). Both risks are rated in terms of numerical relevance and acceptability. METHOD A sample of 448 consecutive women with low-risk pregnancies were interviewed to collect social and clinical variables and to determine their perceptions of the risks of invasive procedure-related miscarriage and carrying a foetus with DS. The risks were scored numerically in terms of their relevance and acceptability using a 10-point rating scale. RESULTS The factors related to the use of non-invasive tests were age ≥35 years, not being treated at a public service, rating the risk of carrying a foetus with DS as having high numerical relevance and low acceptability, and rating the risk of miscarriage as having high acceptability. These relationships were still present when the use of invasive tests was considered, except in terms of the numerical relevance of the risk of carrying a foetus with DS. CONCLUSION Perceived acceptability affects the interpretation of a given risk more than the numerical relevance of the risk.

Abstract
The clinical integration of prenatal genetic technologies raises a series of important medical and ethical considerations for patients, families, health care providers, health care systems, and society. It is critical to recognize, understand, and address these issues in conjunction with the continued development of new prenatal genetic screens and tests. This article discusses some of the lead ethical issues as a starting point to further understanding their ramifications on patients, families, communities, and health care providers.

Abstract
Objectives To assess rates of informed choice among women offered non‐invasive prenatal testing (NIPT) for aneuploidy as part of routine clinical care. Methods A cross‐sectional survey was conducted across 6 antenatal clinics in England. Women with a high risk (≥1/150) Down syndrome screening result were offered NIPT, invasive testing, or no further testing. Pretest counselling was delivered as part of routine care by the local maternity team. Women were given a questionnaire containing a measure of informed choice immediately after pretest counselling. Results In total, 220 of 247 women completed the questionnaire. Seventy‐six percent were judged to have made an informed choice, a significant decline from our previous study (89.0% vs 75.6%; χ2(2) = 20.2, P < .001). Of those making an uninformed choice, 46% had insufficient knowledge, 19% had not deliberated, and 13% had made a value‐inconsistent decision. Multivariate analysis showed women who were highly educated (OR, 4.33; 95% CI, 1.08‐17.36) or had had screening in a previous pregnancy (OR, 0.24; 95% CI, 0.90‐0.65) were significantly more likely to make an informed choice. Conclusions The findings highlight the challenges of ensuring informed choice in routine prenatal care where NIPT is not discussed at multiple points, less time is available for counselling, and written consent is not required. What's already known about this topic?
Non‐invasive prenatal testing for aneuploidy is a highly accurate screening test, but concerns exist around potential routinisation. Previous evidence indicated high levels of informed choice are possible, but this was a tightly controlled research setting.
What does this study add?
Non‐invasive prenatal testing can be offered within routine prenatal care in a way that facilitates high levels of informed choice. However, the decline in rates of informed choice compared with those in the research setting highlight the challenges of offering non‐invasive prenatal testing in routine prenatal care.

Abstract
Purpose of Review In 2011, screening platforms became available in the US that detect and analyze fragments of cell-free placental DNA (cfDNA) in maternal blood serum. Marketed as noninvasive prenatal tests (NIPT), cfDNA screening is more accurate than previously available serum screening tests for certain aneuploidies. The combination of a noninvasive procedure, high specificity and sensitivity, and lower false positive rates for some aneuploidies (most notably Down's syndrome) has led to broad clinician and patient adoption. New ethical, legal, and social issues arise from the increased use and expanded implementation of cfDNA in pregnancy. Recent Findings Recently, several professional associations have amended their guidelines on cfDNA, removing language recommending its use in only "high-risk" pregnancies in favor of making cfDNA screening an available option for women with "low-risk" pregnancies as well. At the same time, commercial cfDNA screening laboratories continue to expand the range of available test panels. As a result, the future of prenatal screening will likely include a broader range of genetic tests in a wider range of patients. Summary This article addresses the ethical, legal, and social issues related to the shift in guidance and expanded use of cfDNA in pregnant women, including concerns regarding routinized testing, an unmet and increasing demand for genetic counseling services, social and economic disparities in access, impact on groups living with disabling conditions, and provider liability.

Abstract
Screening for fetal aneuploidy in pregnant women using cell-free DNA has increased dramatically since the technology became commercially available in 2011. Since that time, numerous trials have demonstrated high sensitivity and specificity to screen for common aneuploidies in high-risk populations. Studies assessing the performance of these tests in low-risk populations have also demonstrated improved detection rates compared with traditional, serum-based screening strategies. Concurrent with the increased use of this technology has been a decrease in invasive procedures (amniocentesis and chorionic villus sampling). As the technology becomes more widely understood, available, and utilized, challenges regarding its clinical implementation have become apparent. Some of these challenges include test failures, false-positive and false-negative results, limitations in positive predictive value in low-prevalence populations, and potential maternal health implications of abnormal results. In addition, commercial laboratories are expanding screening beyond common aneuploidies to include microdeletion screening and whole genome screening. This review article is intended to provide the practicing obstetrician with a summary of the complexities of cell-free DNA screening and the challenges of implementing it in the clinical setting.

Abstract
OBJECTIVES The introduction of prenatal cfDNA screening for fetal aneuploidy and other genetic conditions has exacerbated concerns about informed decision-making in clinical prenatal testing. To assess the information provided to patients to facilitate decisions about cfDNA screening, we collected written patient education and consent documents created by laboratories and clinics. METHODS Informed consent documents (IC) were coded by two independent coders. Each IC was assessed for readability, attention to elements of informed consent, and completeness of information about the test and the screened conditions. RESULTS We found variance between IC produced by commercial laboratories versus those provided by local clinics or health care systems, and considerable variance among materials from all sources. "Commercial" IC were longer and written at a more difficult reading level than "non-commercial" IC, and were less likely to state explicitly that cfDNA only screens for certain conditions. About one-third of IC were combined with laboratory order forms. Though most IC recommended confirmatory testing for positive results, only about half clearly stated that results could be incorrect-including mentions of false positives or false negatives. About one-third of IC explicitly stated that cfDNA screening was optional. While nearly all IC from any source listed the conditions screened by the test, only about half of the IC included any phenotypic descriptions of these conditions. Few IC mentioned psychosocial considerations, and only one IC mentioned the availability of support groups for families of children with genetic conditions. CONCLUSIONS Based on our findings, we recommend that written and well-informed consent be sought before performing cfDNA screening, and we offer minimal and recommended standards for patient education and consent materials.

Abstract
Genomics-based non-invasive prenatal screening using cell-free DNA (cfDNA screening) was proposed to reduce the number of invasive procedures in current prenatal diagnosis for fetal aneuploidies. We review here the clinical and ethical issues of cfDNA screening. To date, it is not clear how cfDNA screening is going to impact the performances of clinical prenatal diagnosis and how it could be incorporated in real life. The direct marketing to users may have facilitated the early introduction of cfDNA screening into clinical practice despite limited evidence-based independent research data supporting this rapid shift. There is a need to address the most important ethical, legal, and social issues before its implementation in a mass setting. Its introduction might worsen current tendencies to neglect the reproductive autonomy of pregnant women.

Abstract
Cell-free DNA (cfDNA) testing has recently become indispensable in diagnostic testing and screening. In the prenatal setting, this type of testing is often called noninvasive prenatal testing (NIPT). With a number of techniques, using either next-generation sequencing or single nucleotide polymorphism-based approaches, fetal cfDNA in maternal plasma can be analyzed to screen for rhesus D genotype, common chromosomal aneuploidies, and increasingly for testing other conditions, including monogenic disorders. With regard to screening for common aneuploidies, challenges arise when implementing NIPT in current prenatal settings. Depending on the method used (targeted or nontargeted), chromosomal anomalies other than trisomy 21, 18, or 13 can be detected, either of fetal or maternal origin, also referred to as unsolicited or incidental findings. For various biological reasons, there is a small chance of having either a false-positive or false-negative NIPT result, or no result, also referred to as a "no-call." Both pre- and posttest counseling for NIPT should include discussing potential discrepancies. Since NIPT remains a screening test, a positive NIPT result should be confirmed by invasive diagnostic testing (either by chorionic villus biopsy or by amniocentesis). As the scope of NIPT is widening, professional guidelines need to discuss the ethics of what to offer and how to offer. In this review, we discuss the current biochemical, clinical, and ethical challenges of cfDNA testing in the prenatal setting and its future perspectives including novel applications that target RNA instead of DNA.

Non-invasive prenatal testing for aneuploidy and beyond: challenges of responsible innovation in prenatal screening. Eur J Hum Genet 2015; 23:1438-50.

Abstract
This paper contains a joint ESHG/ASHG position document with recommendations regarding responsible innovation in prenatal screening with non-invasive prenatal testing (NIPT). By virtue of its greater accuracy and safety with respect to prenatal screening for common autosomal aneuploidies, NIPT has the potential of helping the practice better achieve its aim of facilitating autonomous reproductive choices, provided that balanced pretest information and non-directive counseling are available as part of the screening offer. Depending on the health-care setting, different scenarios for NIPT-based screening for common autosomal aneuploidies are possible. The trade-offs involved in these scenarios should be assessed in light of the aim of screening, the balance of benefits and burdens for pregnant women and their partners and considerations of cost-effectiveness and justice. With improving screening technologies and decreasing costs of sequencing and analysis, it will become possible in the near future to significantly expand the scope of prenatal screening beyond common autosomal aneuploidies. Commercial providers have already begun expanding their tests to include sex-chromosomal abnormalities and microdeletions. However, multiple false positives may undermine the main achievement of NIPT in the context of prenatal screening: the significant reduction of the invasive testing rate. This document argues for a cautious expansion of the scope of prenatal screening to serious congenital and childhood disorders, only following sound validation studies and a comprehensive evaluation of all relevant aspects. A further core message of this document is that in countries where prenatal screening is offered as a public health programme, governments and public health authorities should adopt an active role to ensure the responsible innovation of prenatal screening on the basis of ethical principles. Crucial elements are the quality of the screening process as a whole (including non-laboratory aspects such as information and counseling), education of professionals, systematic evaluation of all aspects of prenatal screening, development of better evaluation tools in the light of the aim of the practice, accountability to all stakeholders including children born from screened pregnancies and persons living with the conditions targeted in prenatal screening and promotion of equity of access.

Abstract
OBJECTIVE The aim of this study was to investigate health professionals' opinions toward offering noninvasive prenatal testing (NIPT) as first-tier screening test regardless of pregnant women's risk, and toward a potential broader range of disorders. METHODS A questionnaire completed by obstetric health professionals (n = 240) after an in-service NIPT training in the West and North of the Netherlands. RESULTS The majority (72%) of respondents favored replacing first-trimester combined test (FCT) by NIPT, although 43% preferred to maintain nuchal translucency measurement. Many respondents believed that replacing FCT by NIPT would only have advantages (57%), would lead to more pregnant women opting for prenatal testing (69%), and would simplify counseling (47%). Differences in attitudes toward counseling between health professionals were observed. When considering NIPT to screen for broader range of disorders, the majority (92%) thought that this should include disorders characterized by neonatal death, whereas 52% of the respondents favored testing for fetomaternal risk factors. Overall, 46% thought screening should be offered as a fixed list of disorders. CONCLUSION Most health professionals favor NIPT instead of FCT but prefer to maintain nuchal translucency measurement. If NIPT becomes available as a first-tier screening test, attention remains necessary to ensure that pregnant women make well-informed decisions in line with the aim of prenatal screening.

Abstract
OBJECTIVE To investigate whether the introduction of non-invasive pre-natal testing for Down's syndrome (DS) has the potential to undermine informed choice. PARTICIPANTS Three hundred and ninety-three health professionals; 523 pregnant women. METHODS A cross-sectional questionnaire study across nine maternity units and three conferences in the UK designed to assess opinions regarding test delivery and how information should be communicated to women when offered Down's syndrome screening (DSS) or diagnosis using invasive (IDT) or non-invasive testing (NIPT). RESULTS Both pregnant women and health professionals in the NIPT and DSS groups were less likely than the IDT group to consider that testing should take place at a return visit or that obtaining written consent was necessary, and more likely to think testing should be carried out routinely. Compared to health professionals, pregnant women expressed a stronger preference for testing to occur on the same day as pre-test counselling (P = 0.000) and for invasive testing to be offered routinely (P = 0.000). They were also more likely to indicate written consent as necessary for DSS (P = 0.000) and NIPT (P < 0.05). CONCLUSIONS Health professionals and pregnant women view the consenting process differently across antenatal test types. These differences suggest that informed choice may be undermined with the introduction of NIPT for DS into clinical practice. To maintain high standards of care, effective professional training programmes and practice guidelines are needed which prioritize informed consent and take into account the views and needs of service users.

Abstract
Non-invasive prenatal testing (NIPT) via fetal DNA in maternal blood has been publicly funded in Ontario, Canada, for high-risk women since 2014. We solicited women's experiences and values related to this new health technology to describe how this test is currently being used in Ontario and to provide information about patient priorities to inform future policy decisions about the use of NIPT. Guided by constructivist grounded theory methodology, we interviewed 38 women who had diverse personal experiences with NIPT. Participants' accounts of their values for decision making about NIPT heavily relied on three mutually modulating factors: timing, accuracy, and risk. The values expressed by women conflict with the way that publicly funded NIPT has typically been implemented in Ontario. We offer recommendations for how NIPT might be integrated into prenatal care pathways in a way more consistent with women's values.

Abstract
OBJECTIVE The aim of the study is to study pregnant women's views on noninvasive prenatal testing (NIPT) for Down syndrome and the potential to test for a broader range of conditions. METHODS An online questionnaire available on the Dutch pregnancy fair website was completed by 381 pregnant women. RESULTS Of the women, 51% expressed interest in having NIPT, including 33% of women who had declined first-trimester screening. The majority (73%) thought that the uptake of screening would increase with NIPT. Most women agreed that testing for life-threatening (89%), severe physical (79%), or severe mental (76%) disorders should be offered. A minority (29%) felt that prenatal screening should also be offered for late-onset disorders. Most (41%) preferred to have a free choice from a list of disorders, 31% preferred a 'closed offer', and 26% preferred choosing between packages of disorders. Although most women (76%) thought that screening for a broad range of conditions would avoid much suffering, 39% feared that it would confront couples with choices, the implications of which would be difficult to grasp. CONCLUSION The results suggest that the uptake of screening will increase with NIPT. If NIPT will be offered for a broad range of conditions, it is crucial to find a way that facilitates rather than undermines well-informed decision-making.

Abstract
BACKGROUND The recent availability of new non-invasive prenatal genetic tests for fetal aneuploidy has raised questions concerning whether and how these new tests will be integrated into prenatal medical care. Among the many factors to be considered are public understandings and preferences about prenatal testing mechanisms and the prospect of fetal aneuploidy. METHODS To address these issues, we conducted a nation-wide mixed-method survey of 2,960 adults in the United States to explore justifications for choices among prenatal testing mechanisms. Open responses were qualitatively coded and grouped by theme. RESULTS Respondents cited accuracy, followed by cost, as the most significant aspects of prenatal testing. Acceptance of testing was predicated on differing valuations of knowledge and on personal and religious beliefs. Trust in the medical establishment, attitudes towards risk, and beliefs about health and illness were also considered relevant. CONCLUSIONS Although a significant portion of the sample population valued the additional accuracy provided by the new non-invasive tests, they nevertheless expressed concerns over high costs. Furthermore, participants continued to express reservations about the value of prenatal genetic information per se, regardless of how it was obtained.

Abstract
Noninvasive prenatal genetic testing (NIPT) is an advance in the detection of fetal chromosomal aneuploidies that analyzes cell-free fetal DNA in the blood of a pregnant woman. Since its introduction to clinical practice in Hong Kong in 2011, NIPT has quickly spread across the globe. While many professional societies currently recommend that NIPT be used as a screening method, not a diagnostic test, its high sensitivity (true positive rate) and specificity (true negative rate) make it an attractive alternative to the serum screens and invasive tests currently in use. Professional societies also recommend that NIPT be accompanied by genetic counseling so that families can make informed reproductive choices. If NIPT becomes more widely adopted, States will have to implement regulation and oversight to ensure it fits into existing legal frameworks, with particular attention to returning fetal sex information in areas where sex-based abortions are prevalent. Although there are additional challenges for NIPT uptake in the developing world, including the lack of health care professionals and infrastructure, the use of NIPT in low-resource settings could potentially reduce the need for skilled clinicians who perform invasive testing. Future advances in NIPT technology promise to expand the range of conditions that can be detected, including single gene disorders. With these advances come questions of how to handle incidental findings and variants of unknown significance. Moving forward, it is essential that all stakeholders have a voice in crafting policies to ensure the ethical and equitable use of NIPT across the world.

Abstract
Genetic screening and health-care guidelines recommend that programmes should facilitate informed choice. It is therefore important that accurate measures of informed choice are available to evaluate such programmes. This review synthesises and appraises measures used to evaluate informed choice in population-based genetic screening programmes for reproductive risk. Databases were searched for studies offering genetic screening for the purpose of establishing reproductive risk to an adult population sample, in which aspects of informed choice were measured. Studies were included if, at a minimum, measures of uptake of screening and knowledge were used. Searches identified 1462 citations and 76 studies were reviewed in full text; 34 studies met the inclusion criteria. Over 20 different measures of informed choice were used. Many measures lacked adequate validity and reliability data. This systematic review will inform future evaluation of informed choice in population genetic screening programmes.

Abstract
New technologies analyzing fetal DNA in maternal blood have led to the wide commercial availability of non-invasive prenatal testing (NIPT). We present here for clinicians the ethical and policy issues related to an emerging practice option. Although NIPT presents opportunities for pregnant women, particularly women who are at increased risk of having a baby with an abnormality or who are otherwise likely to access invasive prenatal testing, NIPT brings significant ethics and policy challenges. The ethical issues include multiple aspects of informed decision-making, such as access to counselling about the possible results of the test in advance of making a decision about participation in NIPT. Policy considerations include issues related to offering and promoting a privately available medical strategy in publicly funded institutions. Ethics and policy considerations merge in NIPT with regard to sex selection and support for persons living with disabilities.

Abstract
Objectives: To investigate how the introduction of noninvasive prenatal testing (NIPT) influenced women's testing choices following a positive Down syndrome screening. Methods: A retrospective study was conducted to compare differences in the uptake rates of invasive prenatal diagnosis (IPD) or no testing in one public hospital 1 year before (pre-NIPT) and 1 and 2 years after the introduction of NIPT in private in August 2011 using descriptive analysis and a χ2 test. Conventional screening was funded publicly, but NIPT was not. Multivariable binary logistic regression was used to determine factors affecting choices. Results: In pre-NIPT and in years 1 and 2 after the introduction of NIPT, 306, 362 and 401 women who screened positive were seen, respectively. In year 1 and year 2, 12.6 and 26.7% of them underwent NIPT while IPD was decreased by 16.3 and 25.6%, respectively (p < 0.001). Both chorionic villus sampling and amniocentesis decreased in year 1, but only the former in year 2. However, the rate of declining further testing was similar before and after NIPT (p = 0.213). In multivariable analysis, first trimester screening, nulliparity and working women were significant predictors of accepting NIPT, while only nulliparity was a predictor of declining IPD (OR = 0.61). Conclusions: Introduction of NIPT resulted in a significant decrease in IPD for 2 consecutive years.
