Decision making following a prenatal diagnosis of Down syndrome: an integrative review

Awareness of down syndrome screening among educated Muslim women is associated with a favorable attitude toward testing

OBJECTIVE

There is a general assumption that Muslim women refuse Down syndrome screening, and therefore, many health practitioners do not offer it or briefly discuss it with their participants. This study aims to objectively assess women's awareness, knowledge, and attitudes toward Down Syndrome screening (D.S.S) in a Muslim-majority population.

METHODS

We conducted a cross-sectional study among attendees of antenatal clinics at a major university hospital in Saudi Arabia, aiming for a sample size of at least 385 Muslim women. A semi-structured questionnaire assessed awareness of different D.S.S. options and the source of that information (2 items), specific knowledge of D.S.S. (14 items), and attitudes (4 items). The knowledge and attitudes scores were calculated using a five-level agreement Likert-type scale.

RESULTS

Among 434 participants, with an even distribution among all age groups and a majority of a college degree holder or higher (71%), 178 (41.0%) reported awareness of D.S.S. Factors associated with increased awareness were maternal age above 40 or those under 30, nulliparity, and extended family history of fetal congenital anomalies (P-value = 0.03,0.015, and 0.017, respectively). Recognized tests were ultrasound measurement of nuchal translucency (71.9%) and first-trimester serum screening (58.4%). The sources of knowledge were obstetricians (53.9%), followed by family and friends (27.0%). The overall mean ± SD knowledge score was 53.9 ± 8.7 out of 70, and the mean attitude score was 17.4 ± 2.9 out of 20. Having 1 or 2 children is associated with a higher knowledge score, and most participants who reported awareness of D.S.S. (51.7%) had a favorable attitude toward screening.

CONCLUSION

Awareness of D.S.S. among Muslim women is associated with favorable attitudes towards testing, contradicting the general assumption and highlighting the need for systematic education to increase awareness and subsequent testing uptake.

Vocational identity in decision-making for terminating/continuation of pregnancy following non-invasive prenatal testing and hypothetical diagnosis among Japanese university students

The use of prenatal testing in Japan is expected to increase. However, there are ethical concerns regarding pregnancy termination upon the detection of fetal chromosomal abnormalities, such as Down syndrome. Furthermore, factors associated with decision-making following a positive result of Down syndrome after prenatal screening remain unclear. Therefore, we aimed to evaluate the association between decision-making among university students following a hypothetical positive result of Down syndrome in prenatal screening and their perception of their future career development defined as vocational identity. This cross-sectional study included 256 individuals (109 men, 143 women, and four who preferred not to answer). Self-anonymous semi-structured questionnaires were distributed to collect information regarding socio-demographic characteristics, vocational identity, and decision-making following a positive prenatal screening result of Down syndrome. Vocational identity was assessed using the Vocational Identity Measure. Women students were more likely to intend to continue the pregnancy (76.9%, p < 0.05); however, students without siblings (68.2%, p < 0.01) and men and women students with higher scores for vocational identities who were raised in an academically oriented family were more likely to intend to terminate the pregnancy (p < 0.05). Therefore, gender and vocational identity were associated with decision-making following a positive result of Down syndrome. Further qualitative and quantitative studies on factors associated with decision-making following a positive result of Down syndrome are necessary to eliminate the burden and social barrier, including gender division of labor and the effect of vocational career for people wishing to parent a child with Down syndrome.

Psychological wellbeing in parents of children with Down syndrome: A systematic review and meta-analysis

We report a review examining the psychological wellbeing of parents of children with Down syndrome (DS) relative to that of parents of typically developing (TD) children. A systematic search identified 57 relevant studies, which were synthesised meta-analytically. Relative to their counterparts with TD children, mothers and fathers of children with DS reported higher levels of parenting stress (mothers: g = 0.57, 95% CI [0.33, 0.81]; fathers: g = 0.40, [0.24, 0.56]), depressive symptoms (mothers: g = 0.42, [0.23, 0.61]; fathers: g = 0.25, [0.02, 0.48]) and psychological distress (mothers: g = 0.45, [0.30, 0.60]; fathers: g = 0.63, [0.26, 0.99]). Small effects were found for anxiety for mothers (g = 0.16, [0.03, 0.29]), with no differences for fathers (g = 0.03, [-0.25, 0.32]). No group differences were found for positive impact of parenting (mothers: g = -0.09, [-0.25, 0.07]; fathers: g = -0.04, [-0.30, 0.22]), while evidence concerning other positive wellbeing outcomes was limited. No significant moderating effects of child age range, country income level, or group differences in parental education level were identified, but limited subgroup analyses were possible. Raising a child with DS may be associated with elevated stress, depressive symptoms, and psychological distress for mothers and fathers. However, levels of parenting reward appear equivalent to those experienced by parents raising TD children.

Conditions for autonomous reproductive decision-making in prenatal screening: A mixed methods study

BACKGROUND

Pregnant women should be able to make autonomous and meaningful decisions about prenatal screening for fetal abnormalities. It remains largely unclear which circumstances facilitate or hinder such a decision-making process.

OBJECTIVE

To investigate what conditions Dutch pregnant women and professional experts consider important for autonomous reproductive decision-making in prenatal screening for fetal abnormalities, and the extent to which, according to women, those conditions are met in practice.

METHODS

A mixed methods study was conducted in the Netherlands in 2016-2017. A conceptual model was used to interview professional experts (n = 16) and pregnant women (n = 19). Thematic analysis was performed to identify important conditions. Subsequently, a questionnaire assessed the perceived importance of those conditions and the extent to which these were met, in the experience of pregnant women (n = 200).

RESULTS

Professional experts stressed the importance of information provision, and emphasized a rational decision-making model. Pregnant women differed in what information they felt was needed, and this depended on the screening decision made. Questionnaire findings showed that women prioritized discussion and consensus with partners. Information about test accuracy and miscarriage risk of invasive follow-up testing was also considered important. Two key conditions were not adequately met, in the experience of women: (1) having information about miscarriage risk; (2) not being directed by health professionals in decision-making.

CONCLUSION

According to women, discussion and consensus with partners was considered a highly important condition for an autonomous and meaningful decision-making process. Access to information about safety of testing and ensuring that women are not being directed in their decision-making by health professionals seem to be areas for improvement in prenatal care practice.

Do online decision aids reflect new prenatal screening and testing options? An environmental scan and content analysis

Objective

Decision aids have been developed to help prospective parents make informed, shared decisions about medical tests, but these options are rapidly changing. This study aimed to identify and evaluate publicly available decision aids written in English for prospective parents seeking prenatal test information.

Methods

A systematic review process was followed using 3 sources: known decision aid repositories, fetal medicine organisations and Google. The search, screening process, quality assessment, and data extraction was performed by two independent researchers. The quality assessment of the decision aids was based on the International Patient Decision Aids Standards (IPDAS v.4.0).

Results

We identified 13 decision aids, which varied in the screening and diagnostic tests that they discussed. No decision aid met all the IPDAS v.4.0. criteria and no decision aid reported updated risk of miscarriage for amniocentesis and chorionic villus sampling (CVS). There was a lack of decision aids for some common decisions in the prenatal context.

Conclusion

We identified outdated content in current prenatal decision aids. The findings will inform healthcare professionals of the quality of current prenatal decision aids, which may facilitate their patients' informed decision-making about prenatal tests.

Innovation

Considerations for improving future decision aids are outlined.

Social preferences or sacred values? Theory and evidence of deontological motivations

Recent advances in economic theory, largely motivated by experimental findings, have led to the adoption of models of human behavior where decision-makers take into consideration not only their own payoff but also others' payoffs and any potential consequences of these payoffs. Investigations of deontological motivations, where decision-makers make their choice based on not only the consequences of a decision but also the decision per se, have been rare. We provide a formal interpretation of major moral philosophies and a revealed preference method to distinguish the presence of deontological motivations from a purely consequentialist decision-maker whose preferences satisfy first-order stochastic dominance.

Clinical Course and Outcome of Non-Immune Fetal Hydrops in Singleton Pregnancies

Nonimmune fetal hydrops is a condition defined by abnormal fluid accumulation in two or more body compartments. The aim is to evaluate factors associated with adverse outcome in diagnosed fetal hydrops and to investigate the aspects for the decision making in the case of termination of pregnancy. Therefore, a retrospective data analysis of pregnancies complicated by non-immune hydrops fetalis between 2004 and 2018 was performed in a single tertiary referral center. Of 361 pregnancies with diagnosed fetal hydrops, in 183 cases (50.7%), the parents decided to terminate the pregnancy. A strong relationship between etiology and termination of pregnancy was demonstrated, whereas the highest rates of termination of pregnancy were found if a chromosomal aberration was diagnosed. Of the remaining 178 cases, 51 cases (28.7%) had a miscarriage, 33 cases (18.5%) had an intrauterine fetal death, and 94 cases (52.8%) were live born, whereas 26 (27.7%) of these offspring died within the first week of life. The risk of an adverse outcome increased with lower gestational age at diagnosis (p < 0.001). A nuchal translucency thickness greater than 2.5 mm was associated with an adverse outcome (p < 0.01). Furthermore, pregnancies with adverse outcome had significantly more affected compartments (median: 3; IQR 2), compared with live born cases (median: 2; IQR 1; p < 0.01). In conclusion, adverse outcome in pregnancies with fetal hydrops was associated with a lower gestational age at diagnosis, nuchal translucency greater than 2.5 mm and a higher count of affected compartments. These results confirm that a precise clinical workup to identify the underlying etiology of non-immune fetal hydrops is essential for a better prognostic assessment and accurate counselling of parents.

Fetal information as shared information: using NIPT to test for adult-onset conditions

The possibilities of non-invasive prenatal testing (NIPT) are expanding, and the use of NIPT for adult-onset conditions may become widely available in the near future. If parents use NIPT to test for these conditions, and the pregnancy is continued, they will have information about the child's genetic predisposition from birth. In this paper, we argue that prospective parents should be able to access NIPT for an adult-onset condition, even when they have no intention to terminate the pregnancy. We begin by outlining the arguments against testing in such a situation, which generally apply the same considerations that apply in the predictive testing of a minor to the fetus in utero. We then contend, firstly, that there are important practical considerations that support availability of testing for prospective parents regardless of their stated intentions. Secondly, we object to the ethical equation of a fetus in utero with a minor. We base our analysis on a view of pregnancy that conceptualises the fetus as a part of the gestational parent, as opposed to the more common 'container' model of pregnancy. We suggest that fetal information is best conceptualised as shared information between the gestational parent and future child. Thus, it should be approached in similar ways as other kinds of shared information (such as genetic information with implications for family members), where a person has a claim over their own information, but should be encouraged to consider the interests of other relevant parties.

The Natural History of Trisomy 21: Outcome Data from a Large Tertiary Referral Centre

OBJECTIVE

The aim of the study was to prospectively gather data on pregnancy outcomes of prenatally diagnosed trisomy 21 (T21) in a large tertiary referral centre.

METHODS

Data were gathered prospectively in a large tertiary referral centre over 5 years from 2013 to 2017 inclusively. Baseline demographic and pregnancy outcome data were recorded on an anonymized computerized database.

RESULTS

There were 1,836 congenital anomalies diagnosed in the study period including 8.9% (n = 165) cases of T21. 79% (n = 131) were age 35 or older at diagnosis. 79/113 (69.9%) women chose a termination of pregnancy (TOP) following a diagnosis of T21. Amongst pregnancies that continued, there were 4 second-trimester miscarriages (4/34, 11.7%), 9 stillbirths (9/34, 26.4%), and 1 neonatal death, giving an overall pregnancy and neonatal loss rate of 14/34 (41.1%).

CONCLUSION

The risk of foetal loss in prenatally diagnosed T21 is high at 38% with an overall pregnancy loss rate of 41.1%. This information may be of benefit when counselling couples who are faced with a diagnosis of T21 particularly in the context of limited access to TOP.

Factors That Influence Parents' Decision-Making Regarding Termination of Pregnancy After Prenatal Diagnosis of Fetal Congenital Heart Disease

OBJECTIVE

To explore factors that influence parents' decisions regarding the termination of pregnancy after the detection of fetal congenital heart disease (CHD).

DESIGN

A prospective descriptive study.

SETTING

The Institute of Pediatric Cardiology in the Schneider Children's Medical Center.

PARTICIPANTS

One hundred twenty couples (240 participants) with fetuses prenatally diagnosed with CHD, which was defined as conditions requiring surgical treatment.

METHODS

We obtained data from a structured questionnaire for the pediatric cardiologist, the medical records, and structured self-report questionnaires for the participants.

RESULTS

Thirty-six of 120 couples (30%) decided to terminate the pregnancy after a prenatal diagnosis of fetal CHD. The main factors associated with the decision to terminate were low gestational age (OR = 0.83 per week, 95% confidence interval [CI] [0.75, 0.96]), severe cardiac malformation (OR = 2.23, 95% CI [1.40, 3.53]), religious affiliation (OR = 10.0 for secular participants vs. others, 95% CI [4.61, 22.46], population group (OR = 2.96 for Jewish participants vs. others, 95% CI [1.63, 11.3]), and education (OR = 1.34 per year of education, 95% CI [1.15, 1.55]).

CONCLUSIONS

Our findings describe the profiles of couples who decided to terminate their pregnancies after a prenatal diagnosis of fetal CHD. Early identification of the couple's decision can help health care providers provide adequate support, counseling, and guidance. Future research is needed to understand parents' needs for support through the process of decision-making, with attention to their religious and cultural values and contexts.

Factors affecting Thai pregnant women's decisions concerning prenatal diagnosis and termination of pregnancy for β-thalassemia

AIM

To investigate the factors influencing decisions concerning prenatal diagnosis (PND) and termination of pregnancy for β-thalassemia in Thai pregnant women.

METHODS

A total of 142 Thai Buddhist pregnant women waiting for PND were asked to undertake semi-structured interviews regarding their reasons for PND and their decisions and reasoning concerning pregnancy if the fetus was found to be affected. The interviews were analyzed using a thematic content approach.

RESULTS

Thai pregnant women accepted PND for three reasons: to know whether their pregnancies were affected, to confirm that their pregnancies were unaffected and to terminate if their pregnancies were affected. Three decisions identified among the women were to terminate the pregnancy, to continue the pregnancy and undecided. The interview analysis identified five themes and nine sub-themes affecting pregnancy-related decision-making: (i) quality of life (suffering or no disability); (ii) burden (difficulty or acceptability); (iii) sense of motherhood (the best way for the child or I cannot hurt my child); (iv) significant others (support to terminate, support to continue or support to wait for the test result) and (v) conflict in deciding.

CONCLUSION

An acceptance of PND in Thai pregnant women was not always associated with pregnancy termination. Multiple factors influenced the decision to terminate, but not their religious affiliation.

Sociodemographic Differences in Prenatal Diagnosis of Chromosomal Anomalies: A Population-Based Study

Background: In Europe, about 76% of cases of chromosomal anomalies are prenatally diagnosed. Prenatal diagnosis allows more efficient planning of postnatal treatment and helps parents for an informed decision about the continuation of pregnancy. The main aim of this study was to evaluate whether the sociodemographic maternal characteristics affect the probability of prenatal diagnosis of chromosomal anomalies. Methods: Cases of chromosomal anomalies in the period 2005-2017 came from the population-based registry of congenital anomalies of Tuscany (Italy). Differences in the proportion of cases prenatally diagnosed were investigated through the following maternal characteristics: education, geographic origin and occupation. The association between cases of termination of pregnancy after prenatal diagnosis and maternal characteristics was also analysed. Odds Ratios (OR) adjusted by maternal age were calculated using logistic regression models. Results were provided for all cases of chromosomal anomalies and for Down syndrome cases. Results: A total of 1,419 cases were included in the study. Cases prenatally diagnosed were 1,186 (83.6%). We observed a higher proportion of cases not prenatally diagnosed among cases with low maternal education compared to those with high maternal education (OR = 2.16, p < 0.001) and in women from high migratory outflow countries, compared to the Italian ones (OR = 2.85, p < 0.001). For prenatally diagnosed Down syndrome cases, we observed a higher proportion of termination of pregnancy for women with low education level (OR = 4.36, p = 0.023). Conclusions: In our study evidence of differences in the probability of prenatal diagnosis of chromosomal anomalies associated with maternal education and geographic origin was found. Population-based studies investigating sociodemographic disparities can provide essential information for targeted public health programs. Further studies are recommended to monitor the impact of the increasing availability of non-invasive screening tests.

Culpable Ignorance, Professional Counselling, and Selective Abortion of Intellectual Disability

In this paper I argue that selective abortion for disability often involves inadequate counselling on the part of reproductive medicine professionals who advise prospective parents. I claim that prenatal disability clinicians often fail in intellectual duty-they are culpably ignorant about intellectual disability (or do not disclose known facts to parents). First, I explain why a standard motivation for selective abortion is flawed. Second, I summarize recent research on parent experience with prenatal professionals. Third, I outline the notions of epistemic excellence and deficiency. Fourth, I defend culpable ignorance as the best explanation of inadequate disability counselling. Fifth, I rebut alternative explanations. My focus is pregnancies diagnosed with mild or moderate intellectual disability.

Abortion in women with Down syndrome

BACKGROUND

Nearly two-thirds of pregnancies in women with Down syndrome (DS) end in abortion. The aim of the present study was to determine if these high abortion rates might relate to specific characteristics of women with DS, their life situation and the course of pregnancy.

METHODS

In a sample of 351 pregnancies in Switzerland (1998 to 2009), women with DS were compared with women with other forms of intellectual disability (ID) and women without ID, regarding the type of abortion, personal characteristics and pregnancy complications that might increase the probability of abortion.

RESULTS

All abortions among women with DS were medically induced. In women with DS and ID, abortions were more likely to occur due to unwanted pregnancy than in women without ID. In addition, women with DS and ID were more often diagnosed with fetal complications and maternal health problems. However, no correlation between fetal complications or maternal health problems and pregnancy outcome was found.

CONCLUSIONS

The group differences found do not directly explain the high abortion rates among women with DS. Maternal diagnosis of DS appears to be the most important predictor of abortion. Possible explanations for this finding are discussed.

Pregnant women's attitudes and decision-making regarding prenatal Down syndrome screening and diagnosis: scale development and validation

Background

Down syndrome is a common chromosomal abnormality and prenatal screening can inform parents of the risk of their baby having Down syndrome. Little research has examined how decisions regarding both Down syndrome screening as well as diagnosis are made among women who are currently pregnant and how their decisions are influenced by their social contexts, specifically family and social media, using mixed methods. The study was to test the validity and reliability of a scale that measures pregnant women’s attitudes and decision-making concerning prenatal Down syndrome screening and diagnosis in urban areas of Taiwan.

Methods

We developed an item pool based on a literature review and in-depth interviews with 30 pregnant women recruited at two district hospitals in urban areas. The item pool was reviewed by a panel of experts and then administered to 300 women who had been pregnant for less than 24 weeks and had not received the Down syndrome screening tests. We used item analysis and exploratory factor analysis to validate the scale and test its reliability.

Results

The initial item pool had 54 items. After the expert review, three items were deleted. After the item analysis, 16 additional items were deleted. Exploratory factor analysis of the remaining items revealed four factors labeled – “Attitudes towards Down syndrome and Screening Tests,” “Important others’ Attitudes towards Down Syndrome,” “Influence of Important Others on Decision-Making,” and “Influence of Social Media on Decision-Making” – and 16 of the remaining items had satisfactory loadings on those factors, explaining 72.0% of the total variance. The Cronbach’s α values of the dimensions ranged between 0.75 and 0.90, demonstrating satisfactory internal reliability.

Conclusions

The scale has satisfactory validity and reliability, and can be used to understand pregnant women’s attitudes and decision-making regarding Down syndrome screening and diagnosis, and to help design tailored consultations for pregnant women in clinical settings.

"This is the child we were given": A qualitative study of Danish parents' experiences of a prenatal Down syndrome diagnosis and their decision to continue the pregnancy

OBJECTIVES

Termination rates when Down syndrome (DS) is diagnosed prenatally are high in most countries. Thus, the present study aimed to explore how parents of prenatally diagnosed children with DS experienced the diagnostic process and their decision to continue the pregnancy.

METHODS

Data from a semi-structured, qualitative interview study with eight mothers and five fathers of prenatally diagnosed children with DS born between 2008 and 2017 were analyzed using thematic analysis.

FINDINGS

Several couples emphasized how they had not hoped for a child with DS, but following the diagnosis they strongly felt that this was the child that they "were given." The couples stressed that DS was not the worst that could happen. All couples sought experiential knowledge outside the hospital setting to explore the potential for living a fulfilling life with DS. Five couples had positive recollections of the delivery of the DS result. Three couples had negative recollections, mainly because the intention to terminate had been taken for granted. After the decision to continue pregnancy was made, their interaction with health-care professionals was generally experienced as positive and supporting. However, some couples still felt vulnerable because they were aware that their decision was uncommon.

CONCLUSIONS

Health-care professionals must be careful to speak in unprejudiced ways throughout the diagnostic process and present both termination and continuation of pregnancy as equally legitimate options. Nevertheless, the couples may still experience doubt and feel vulnerable following their decision to continue the pregnancy.

Epistemic Virtue, Prospective Parents and Disability Abortion

Research shows that a high majority of parents receiving prenatal diagnosis of intellectual disability terminate pregnancy. They have reasons for rejecting a child with intellectual disabilities-these reasons are, most commonly, beliefs about quality of life for it or them. Without a negative evaluation of intellectual disability, their choice makes no sense. Disability-based abortion has been critiqued through virtue ethics for being inconsistent with admirable moral character. Parental selectivity conflicts with the virtue of acceptingness (the commitment to welcome whatever child comes naturally) and exhibits the vice of wilfulness (the project of picking and choosing what children one will take). In this paper I claim that, beyond failures of moral virtue, disability abortion often involves failures of epistemic virtue on the part of parents. I argue two things: parents believe something false, or at least contested, about life with intellectual disability-and they do so because they are not epistemically conscientious. I first explain why a central motivation for disability abortion-that it prevents harm to the child-is mistaken. I next give a brief account of intellectual virtue and culpable ignorance. I then indicate why many parents fail to be intellectually virtuous when choosing to terminate pregnancy. I focus on elimination of intellectual disability and have little to say about physical and sensory impairments.

'Is it better not to know certain things?': views of women who have undergone non-invasive prenatal testing on its possible future applications

Non-invasive prenatal testing (NIPT) is at the forefront of prenatal screening. Current uses for NIPT include fetal sex determination and screening for chromosomal disorders such as trisomy 21 (Down syndrome). However, NIPT may be expanded to many different future applications. There are a potential host of ethical concerns around the expanding use of NIPT, as examined by the recent Nuffield Council report on the topic. It is important to examine what NIPT might be used for before these possibilities become consumer reality. There is limited research exploring views of women on possible future uses of NIPT, particularly those of women who have undergone NIPT. In this study, we examined the views of women who undertook NIPT previously on the acceptability of and interest levels in using NIPT for a number of current and possible future applications. These included several medical conditions encompassing psychiatric, neurodevelopmental and adult-onset conditions as well as non-medical traits such as intelligence. One thousand women were invited to participate and 235 eligible surveys were received. Women generally reported an interest in using NIPT for medical conditions that severely impacted quality of life and with an onset earlier in life and stressed the importance of the accuracy of the test. Concerns were raised about the use of NIPT for non-medical traits. Respondents indicated that termination of pregnancy was not their only reason for testing, particularly in the case of sex. These results can further inform the ethical debate around the increasing integration of NIPT into healthcare systems.

"He looks gorgeous" - iuMR images and the transforming of foetal and parental identities

The MERIDIAN study examined whether in-utero MRI (iuMRI) improves the accuracy of diagnosis of foetal brain abnormalities, when used as an adjunct to ultrasound anomaly scanning. A diagnostic iuMRI differs from routine ultrasound screening because of its infrequent use and scanning procedure. Nested within this trial, this sociological study explored the acceptability of iuMRI as a technology and its contribution to parental decision-making. Our sociological interpretation of the role of iuMR images in prenatal diagnosis draws on narrative interviews with women (and some partners) who underwent MRI imaging at three different centres. Overall, participants found iuMRI helpful in decision-making because it either confirmed or disconfirmed previous results, or provided additional information. Expectant couples experienced the iuMR imaging process as informative, but also as having emotive and practical value. Our paper extends the existing sociological literature on antenatal testing and visualising the foetus, by using iuMR diagnostic imaging to further explore the concept of the unborn entity. Our data suggest that alongside the iuMR images, the 'parental gaze' and accompanying commentary are used by parents to construct and transform foetal and parental identities despite ongoing uncertainties about, and shifting social contexts to their pregnancy.

Stakeholders' views on the value of outcomes from clinical genetic and genomic interventions

PURPOSE

Robust evidence about the value of clinical genomic interventions (CGIs), such as genetic/genomic testing or clinical genetic evaluation, is limited. We obtained stakeholders' perspectives on outcomes from CGIs to help inform their value.

METHODS

We used an adapted Delphi expert panel process. Two anonymous survey rounds assessed the value of 44 CGI outcomes and whether a third party should pay for them, with discussion in between rounds.

RESULTS

Sixty-six panelists responded to the first-round survey and 60 to the second. Policy-makers/payers gave the lowest ratings for value and researchers gave the highest. Patients/consumers had the most uncertainty about value and payment by a third party. Uncertainty about value was observed when evidence of proven health benefit was lacking, potential harms outweighed benefits for reproductive outcomes, and outcomes had only personal utility for individuals or family members. Agreement about outcomes for which a third party should not pay included prevention through surgery with unproven health benefits, establishing ancestry, parental consanguinity, and paternity.

CONCLUSION

Research is needed to understand factors contributing to uncertainty and stakeholder differences about the value of CGI outcomes. Reaching consensus will accelerate the creation of metrics to generate the evidence needed to inform value and guide policies that promote availability, uptake, and coverage of CGIs.

Decision satisfaction among women choosing a method of pregnancy termination in the setting of fetal anomalies and other pregnancy complications: A qualitative study

OBJECTIVE

The decision to undergo a surgical or medical method of second-trimester termination for pregnancy complications should be preference-sensitive. Decision satisfaction has not been described in this population; understanding how women describe decision satisfaction in this setting could inform decision support efforts.

METHODS

We conducted qualitative interviews with women one to three weeks after termination who chose either a surgical or medical termination for fetal anomalies, pregnancy complications or fetal demise. We analyzed transcripts using modified grounded theory in an iterative manner with a generative thematic approach.

RESULTS

We interviewed 36 women (24 surgical and 12 medical). Subjects connected decision satisfaction with counseling experiences and their personal values, including (1) importance of adequate information, (2) autonomous decision making, and (3) choosing the method that facilitates coping.

CONCLUSION

Offering women a choice between surgical and medical termination procedures in the setting of pregnancy complications is integral to decision satisfaction. Women in our study reported wanting this decision to be driven by their personal values.

PRACTICE IMPLICATIONS

Women should be able to choose between surgical and medical termination based on preference and not availability of services. Decision support from women's health providers should be based on values clarification and providing accurate information.

Breastfeeding Experiences of Mothers of Children with Down Syndrome

Children with Down syndrome are less likely to be breastfed than typically developing children, and breastfeeding has a lower duration compared to recommendations of the World Health Organization. The aim of this study was to understand the breastfeeding experiences of mothers of children with Down syndrome, including their perceptions of the breastfeeding process and their specific practices. This is a qualitative study with 10 participants, mothers of children aged between 2 months and 9 years. Snowball sampling was used for participants' selection, and semi-structured interviews conducted in participants' households. Three categories emerged: "the breastfeeding experience," involving the process of breastfeeding, the breast milk, feelings, and difficulties of this practice; "experiences of health care," encompassing the support received by health professionals, dissatisfaction with health services, lack of support in breastfeeding, and discontent with health professional behavior; and "learning about Down syndrome," with search for information by parents and advice to health professionals. In this study, we found evidence that breastfeeding success relies very much on mothers' willingness and support of health professionals, namely, nurses. Findings from this study suggest that support of a multidisciplinary team is essential to the success of breastfeeding. Greater awareness is needed regarding the unique rewards and challenges of breastfeeding these infants, as well as how families cope with the ongoing challenges. Therefore, this research is relevant to understand the experiences of mothers of children with DS about breastfeeding, identifying the inhibiting factors, in order to create more appropriate strategies to intervene and implement practices that contribute to the support and promotion of breastfeeding. Results will also influence the education of health professionals, emphasizing the importance of multidisciplinary teams for a comprehensive care and contributing to increasing evidence available about this topic.

Genomics-based non-invasive prenatal testing for detection of fetal chromosomal aneuploidy in pregnant women

BACKGROUND

Common fetal aneuploidies include Down syndrome (trisomy 21 or T21), Edward syndrome (trisomy 18 or T18), Patau syndrome (trisomy 13 or T13), Turner syndrome (45,X), Klinefelter syndrome (47,XXY), Triple X syndrome (47,XXX) and 47,XYY syndrome (47,XYY). Prenatal screening for fetal aneuploidies is standard care in many countries, but current biochemical and ultrasound tests have high false negative and false positive rates. The discovery of fetal circulating cell-free DNA (ccfDNA) in maternal blood offers the potential for genomics-based non-invasive prenatal testing (gNIPT) as a more accurate screening method. Two approaches used for gNIPT are massively parallel shotgun sequencing (MPSS) and targeted massively parallel sequencing (TMPS).

OBJECTIVES

To evaluate and compare the diagnostic accuracy of MPSS and TMPS for gNIPT as a first-tier test in unselected populations of pregnant women undergoing aneuploidy screening or as a second-tier test in pregnant women considered to be high risk after first-tier screening for common fetal aneuploidies. The gNIPT results were confirmed by a reference standard such as fetal karyotype or neonatal clinical examination.

SEARCH METHODS

We searched 13 databases (including MEDLINE, Embase and Web of Science) from 1 January 2007 to 12 July 2016 without any language, search filter or publication type restrictions. We also screened reference lists of relevant full-text articles, websites of private prenatal diagnosis companies and conference abstracts.

SELECTION CRITERIA

Studies could include pregnant women of any age, ethnicity and gestational age with singleton or multifetal pregnancy. The women must have had a screening test for fetal aneuploidy by MPSS or TMPS and a reference standard such as fetal karyotype or medical records from birth.

DATA COLLECTION AND ANALYSIS

Two review authors independently carried out study selection, data extraction and quality assessment (using the QUADAS-2 tool). Where possible, hierarchical models or simpler alternatives were used for meta-analysis.

MAIN RESULTS

Sixty-five studies of 86,139 pregnant women (3141 aneuploids and 82,998 euploids) were included. No study was judged to be at low risk of bias across the four domains of the QUADAS-2 tool but applicability concerns were generally low. Of the 65 studies, 42 enrolled pregnant women at high risk, five recruited an unselected population and 18 recruited cohorts with a mix of prior risk of fetal aneuploidy. Among the 65 studies, 44 evaluated MPSS and 21 evaluated TMPS; of these, five studies also compared gNIPT with a traditional screening test (biochemical, ultrasound or both). Forty-six out of 65 studies (71%) reported gNIPT assay failure rate, which ranged between 0% and 25% for MPSS, and between 0.8% and 7.5% for TMPS.In the population of unselected pregnant women, MPSS was evaluated by only one study; the study assessed T21, T18 and T13. TMPS was assessed for T21 in four studies involving unselected cohorts; three of the studies also assessed T18 and 13. In pooled analyses (88 T21 cases, 22 T18 cases, eight T13 cases and 20,649 unaffected pregnancies (non T21, T18 and T13)), the clinical sensitivity (95% confidence interval (CI)) of TMPS was 99.2% (78.2% to 100%), 90.9% (70.0% to 97.7%) and 65.1% (9.16% to 97.2%) for T21, T18 and T13, respectively. The corresponding clinical specificity was above 99.9% for T21, T18 and T13.In high-risk populations, MPSS was assessed for T21, T18, T13 and 45,X in 30, 28, 20 and 12 studies, respectively. In pooled analyses (1048 T21 cases, 332 T18 cases, 128 T13 cases and 15,797 unaffected pregnancies), the clinical sensitivity (95% confidence interval (CI)) of MPSS was 99.7% (98.0% to 100%), 97.8% (92.5% to 99.4%), 95.8% (86.1% to 98.9%) and 91.7% (78.3% to 97.1%) for T21, T18, T13 and 45,X, respectively. The corresponding clinical specificities (95% CI) were 99.9% (99.8% to 100%), 99.9% (99.8% to 100%), 99.8% (99.8% to 99.9%) and 99.6% (98.9% to 99.8%). In this risk group, TMPS was assessed for T21, T18, T13 and 45,X in six, five, two and four studies. In pooled analyses (246 T21 cases, 112 T18 cases, 20 T13 cases and 4282 unaffected pregnancies), the clinical sensitivity (95% CI) of TMPS was 99.2% (96.8% to 99.8%), 98.2% (93.1% to 99.6%), 100% (83.9% to 100%) and 92.4% (84.1% to 96.5%) for T21, T18, T13 and 45,X respectively. The clinical specificities were above 100% for T21, T18 and T13 and 99.8% (98.3% to 100%) for 45,X. Indirect comparisons of MPSS and TMPS for T21, T18 and 45,X showed no statistical difference in clinical sensitivity, clinical specificity or both. Due to limited data, comparative meta-analysis of MPSS and TMPS was not possible for T13.We were unable to perform meta-analyses of gNIPT for 47,XXX, 47,XXY and 47,XYY because there were very few or no studies in one or more risk groups.

AUTHORS' CONCLUSIONS

These results show that MPSS and TMPS perform similarly in terms of clinical sensitivity and specificity for the detection of fetal T31, T18, T13 and sex chromosome aneuploidy (SCA). However, no study compared the two approaches head-to-head in the same cohort of patients. The accuracy of gNIPT as a prenatal screening test has been mainly evaluated as a second-tier screening test to identify pregnancies at very low risk of fetal aneuploidies (T21, T18 and T13), thus avoiding invasive procedures. Genomics-based non-invasive prenatal testing methods appear to be sensitive and highly specific for detection of fetal trisomies 21, 18 and 13 in high-risk populations. There is paucity of data on the accuracy of gNIPT as a first-tier aneuploidy screening test in a population of unselected pregnant women. With respect to the replacement of invasive tests, the performance of gNIPT observed in this review is not sufficient to replace current invasive diagnostic tests.We conclude that given the current data on the performance of gNIPT, invasive fetal karyotyping is still the required diagnostic approach to confirm the presence of a chromosomal abnormality prior to making irreversible decisions relative to the pregnancy outcome. However, most of the gNIPT studies were prone to bias, especially in terms of the selection of participants.

Pregnancy Outcome following Prenatal Diagnosis of Chromosomal Anomaly: A Record Linkage Study of 26,261 Pregnancies

Previous studies have demonstrated the influence of changes in the age at which women give birth, and of developments in prenatal screening and diagnosis on the number of pregnancies diagnosed and terminated with chromosomal anomalies. However, we are unaware of any population studies examining pregnancy terminations after diagnosis of chromosomal anomalies that has included all aneuploidies and the influence of maternal factors. The aims of this study were to examine the association between results of prenatal tests and pregnancy termination, and the proportion of foetuses with and without chromosomal anomalies referred for invasive diagnostic tests over time. Diagnostic information of 26,261 prenatal invasive tests from all genetic service laboratories in Scotland from 2000 to 2011 was linked to Scottish Morbidity Records to obtain details on pregnancy outcome. Binary logistic regression was carried out to test the associations of year and type of diagnosis with pregnancy termination, while controlling for maternal age, neighbourhood deprivation and parity. There were 24,155 (92.0%) with no chromosomal anomalies, 1,483 (5.6%) aneuploidy diagnoses, and 623 (2.4%) diagnoses of anomaly that was not aneuploidy (including translocations and single chromosome deletions). In comparison with negative test results, pregnancies diagnosed with trisomy were most likely to be terminated (adjusted OR 437.40, 95% CI 348.19–549.46) followed by other aneuploid anomalies (adjusted OR 95.94, 95% CI 69.21–133.01). During the study period, fewer pregnancies that were diagnosed with aneuploidy were terminated, including trisomy diagnoses (adjusted OR 0.44, 95% CI 0.26–0.73). Older women were less likely to terminate (OR 0.35, 95% CI 0.28, 0.42), and parity was also an independent predictor of termination. In keeping with previous findings, while the number of invasive diagnostic tests declined, the proportion of abnormal results increased from 6.09% to 10.88%. Systematic advances in prenatal screening have improved detection rates for aneuploidy. This has been accompanied by a reduction in the rate of termination for aneuploidy. This may reflect societal changes with acceptance of greater diversity, but this is speculation, and further research would be needed to test this.

A qualitative study looking at informed choice in the context of non-invasive prenatal testing for aneuploidy

Objective

To explore women's attitudes towards non‐invasive prenatal testing (NIPT) and determine factors influencing their decisions around uptake of NIPT.

Method

We conducted qualitative interviews to assess knowledge, attitude and deliberation amongst women offered NIPT in a public health service. In total, 45 women took part in telephone interviews (79% participation rate).

Results

Most women could recount the key aspects of NIPT discussed during pre‐test counselling but had variable knowledge about Down syndrome. Analysis of women's attitudes towards undergoing NIPT revealed three dominant factors they considered when reflecting on the test: (1) how NIPT compared with alternative testing options, (2) reflections on coping and (3) moral or religious values. Exploring the deliberative process revealed the different paths women take when making decisions. For some, it was an extension of the decision to have Down syndrome screening; some considered it early on following the booking‐in appointment; others made step‐wise decisions about NIPT when it became relevant to them.

Conclusion

Our findings support the importance of personalised counselling, whereby women and their partners have the opportunity to reflect on the implications of the test results in the context of their own lives and values. Our data highlight the influence of personal circumstances on decision‐making. © 2016 The Authors. Prenatal Diagnosis published by John Wiley & Sons, Ltd.

What's Already Known About This Topic?

Non‐invasive prenatal testing (NIPT) for aneuploidies has entered clinical practice, although concerns exist around the potential for routinisation and erosion of informed choice.

Research into informed decision‐making for NIPT is now beginning to emerge, although these are predominantly quantitative studies.

What Does This Study Add?

Participants frequently used a combination of clinical information, personal experiences and moral values to guide action.

For many participants, decision‐making was a multistep deliberative process which occurred as and when new information became available.

Experiences of termination of pregnancy for a fetal anomaly: A qualitative study of virtual community messages

OBJECTIVE

to explore experiences described by posters in Swedish virtual communities before, during and after termination of pregnancy due to a fetal anomaly.

DESIGN

cross-sectional qualitative study of messages in virtual communities. The messages were purposefully selected in 2014 and analyzed with inductive qualitative manifest content analysis.

SETTING

two large and active Swedish virtual communities.

SAMPLE

1623 messages from 122 posters (112 females, 1 male, and 9 did not disclose their sex), written between 2008 and 2014. The majority of the posters were females (91%) with recent experience of termination of pregnancy following different prenatal diagnoses (63% less than one year since the termination).

MEASUREMENTS AND FINDINGS

before the termination, posters experienced an emotional shock and a difficult decision. During the termination, they needed compassionate care from present caregivers, experienced intense emotional and physical pain, lacked an understanding about the abortion, and expressed varied feelings about the option to view the fetus. After the termination, posters used different strategies to come to terms with and accept the decision, experienced a perinatal loss, expressed fears of recurrence, and longed for a new child.

KEY CONCLUSIONS

spanning across the time before, during and after the abortion, women who terminate a pregnancy due to a fetal anomaly express considerable physical and emotional pain, with psychosocial and reproductive consequences.

IMPLICATIONS FOR PRACTICE

information and preparation, including the decision whether or not to view the fetus, are important aspects to consider when caring for individuals who have decided to terminate a pregnancy for a fetal anomaly. The findings indicate a need for structures that offer support to women who suffer from fears of recurrence in future pregnancies.

Demographic and experiential correlates of public attitudes towards cell-free fetal DNA screening

This study seeks to inform clinical application of cell-free fetal DNA (cffDNA) screening as a novel method for prenatal trisomy detection by investigating public attitudes towards this technology and demographic and experiential characteristics related to these attitudes. Two versions of a 25-item survey assessing interest in cffDNA and existing first-trimester combined screening for either trisomy 13 and 18 or trisomy 21 were distributed among 3,164 members of the United States public. Logistic regression was performed to determine variables predictive of interest in screening options. Approximately 47% of respondents expressed an interest in cffDNA screening for trisomy 13, 18, and 21, with a majority interested in cffDNA screening as a stand-alone technique. A significantly greater percent would consider termination of pregnancy following a diagnosis of trisomy 13 or 18 (52%) over one of trisomy 21 (44%). Willingness to consider abortion of an affected pregnancy was the strongest correlate to interest in both cffDNA and first-trimester combined screening, although markedly more respondents expressed an interest in some form of screening (69% and 71%, respectively) than would consider termination. Greater educational attainment, higher income, and insurance coverage predicted interest in cffDNA screening; stronger religious identification also corresponded to decreased interest. Prior experience with disability and genetic testing was associated with increased interest in cffDNA screening. Several of these factors, in addition to advanced age and Asian race, were, in turn, predictive of respondents' increased willingness to consider post-diagnosis termination of pregnancy. In conclusion, divergent attitudes towards cffDNA screening--and prenatal options more generally--appear correlated with individual socioeconomic and religious backgrounds and experiences with disability and genetic testing. Clinical implementation and counseling for novel prenatal technologies should take these diverse stakeholder values into consideration.

Introducing the non-invasive prenatal test for trisomy 21 in Belgium: a cost-consequences analysis

BACKGROUND

The first- and second-trimester screening for trisomy 21 (T21) are reimbursed for all pregnant women in Belgium. Using a cut-off risk of 1:300 for T21, about 5% of all pregnant women are referred for definitive prenatal diagnosis using an invasive test, at a sensitivity of (only) 72.5%. The sensitivity and specificity of the non-invasive prenatal test (NIPT) are over 99% but come at a cost of €460 (£373) per test. The objective is to estimate the consequences of introducing NIPT for the detection of T21.

METHODS

A cost-consequences analysis was performed presenting the impact on benefits, harms and costs. Context-specific real-world information was available to set up a model reflecting the current screening situation in Belgium. This model was used to construct the second and first line NIPT screening scenarios applying information from the literature on NIPT's test accuracy.

RESULTS

Introducing NIPT in the first or second line reduces harm by decreasing the number of procedure-related miscarriages after invasive testing. In contrast with NIPT in the second line, offering NIPT in the first line additionally will miss fewer cases of T21 due to less false-negative test results. The introduction of NIPT in the second line results in cost savings, which is not true for NIPT at the current price in the first line. If NIPT is offered to all pregnant women, the price should be lowered to about €150 to keep the screening cost per T21 diagnosis constant.

CONCLUSIONS

In Belgium, the introduction and reimbursement of NIPT as a second line triage test significantly reduces procedure-related miscarriages without increasing the short-term screening costs. Offering and reimbursing NIPT in the first line to all pregnant women is preferred in the long term, as it would, in addition, miss fewer cases of T21. However, taking into account the government's limited resources for universal reimbursement, the price of NIPT should first be lowered substantially before this can be realised.

Autism spectrum disorders: a qualitative study of attitudes toward prenatal genetic testing and termination decisions of affected pregnancies

In the United States, prenatal genetic testing (PGT) for Autism Spectrum Disorders (ASD) is currently available via clinical genetic services. Such testing may inform parents about their unborn child's risk for ASD, prepare parents for the birth of an affected infant, and allow them to arrange for early interventions. Although PGT for autism has potential benefits, the associated ethical, legal, and social implications (ELSI) should be considered. This first qualitative study employed a hypothetical scenario to explore the attitudes toward PGT and termination decisions of 42 parents of children with ASD. Over half of the participants expressed willingness to undergo PGT for autism. Reasons included better preparation for birth, early and better treatment, termination of affected pregnancy, contribution to research, and curiosity. Of the 31 parents who were either willing or unsure about undergoing the PGT, approximately three-fourths would continue their hypothetical affected pregnancies. Explanations included preparation for birth of the child, bonding or acceptance of existing ASD-affected children, apprehensions about test limitations, and religious concerns. Parents who reported they would terminate the affected pregnancy in this hypothetical situation were primarily Asians. This study contributes to the growing understanding of the ELSI aspects of PGT in clinical practice.

Emotional reactions of mothers who have babies who are diagnosed with Down syndrome

PURPOSE

The aim of this study was to explore a deeper insight into experiences of Turkish mothers living with/diagnosed with Down syndrome (DS) baby.

METHODS

Individual and audiotaped interviews were carried out with 11 women after amniocentesis in Karaman city of Turkey between August 2012 and February 2013. Transcribed semistructured interviews were qualitatively and analyzed using a thematic analysis approach to code and categorize emerging themes.

RESULTS

Three principal themes emerged from the study: mothers' emotional reaction after diagnosed DS, mother and healthcare professional interactions, and mother's coping with diagnosed DS.

CONCLUSIONS

Understanding the experiences of women living with/diagnosed with DS baby enables nurses to devise appropriate strategies to provide better support at every stage and thus helping them to cope with daily life.

Variables influencing pregnancy termination following prenatal diagnosis of fetal chromosome abnormalities

The objective of this study was to identify variables that may influence the decision to terminate or continue a pregnancy affected by a chromosome abnormality. We performed a retrospective cohort analysis of 286 pregnancies diagnosed with a chromosome abnormality following genetic counseling and prenatal diagnosis. Data obtained included procedure type, chromosome results, ethnicity, maternal age, use of fertility treatments, and uptake of genetic counseling after results, among other factors. Wilcoxon rank sum test, Fisher's exact test, and univariate and multivariate logistic regression models were used for data analysis. The overall termination rate in this study was 82.9 %. A lower likelihood to terminate was found in pregnancies with a diagnosis of a sex chromosome abnormality (OR 0.05, p < .0001), Filipina race (OR 0.10, p = .03), and uptake of second genetic counseling session (OR 0.05, p < .0001). Prior history of termination was associated with increased likelihood to terminate (OR 8.6, p = .02). Factors revealing no statistically significant association with termination included maternal age, gestational age, clinic site, fetal gender, ultrasound anomalies, reason for referral and who informed the patient. Our data affirm the complexity of the decision making process and reinforce that providers should refrain from making assumptions regarding a patient's likelihood to terminate based on factors such as maternal age, gestational age, type of procedure, or ultrasound.
