Parental Decisions Regarding a Prenatally Detected Fetal Chromosomal Abnormality and the Impact of Genetic Counseling: An Analysis of 38 Cases with Aneuploidy in Southeast Turkey

What are the ethical issues involved in noninvasive prenatal testing in Japan?

AIMS

Noninvasive prenatal testing (NIPT) of pregnant women has been performed worldwide since 2011, and it is currently performed in more than 90 countries. However, the rate of adoption in Japan remains at less than 2%. This review seeks to identify the ethical and practical issues surrounding noninvasive prenatal screening-including the purpose of the test, its pros and cons, issues surrounding fair treatment, and social factors-to better understand why the adoption rate remains low.

METHODS

This study examines the complex ethical issues surrounding noninvasive prenatal testing, including the purpose of the test, its pros and cons, issues related to fair treatment, and social factors.

RESULTS

Although cell-free DNA analysis for common fetal trisomies using maternal blood is highly accurate, lack of access to such testing and discriminatory attitudes in society remain important barriers. Personal choices such as whether to undergo noninvasive prenatal screening and whether to continue a pregnancy are sometimes criticized by those who believe that it leads to the "selection of life" or discrimination against people with disabilities.

CONCLUSIONS

Obstetrics has changed dramatically in recent years, and prenatal diagnosis technology has also advanced. To keep up with these advances, better information should be provided to ensure the public has a more nuanced understanding of the screening beyond the overused argument that it leads to "selection of life."

Termination of pregnancy following a Down Syndrome diagnosis: decision-making process and influential factors in a Muslim but secular country, Turkey

OBJECTIVES

This study aims to present the termination of pregnancy (TOP) rates and elucidate the decision-making process following a prenatal diagnosis of Trisomy 21 in Turkey.

METHODS

This retrospective single-center study was conducted with 146 pregnant women between January 2016 and December 2019 in a tertiary hospital. Data on maternal characteristics, sonographic findings, indications for chromosome analysis, and educational, religious, and economic factors that can influence the parental decision process were collected.

RESULTS

The TOP rate of Down syndrome (DS) in our center was 78.8%. We concluded that maternal age, earlier diagnosis, indication for chromosome analysis, and previous pregnancies had no effect on the TOP decision. On the other hand, not having a minor or a major sonographic sign, employed mothers, middle- and high-income families, and families having a secondary or higher education tended to terminate the pregnancy affected by DS at statistically higher rates.

CONCLUSIONS

There are many studies worldwide investigating the TOP preferences for DS. However, there is limited data about TOP rates and influential factors affecting the decision-making process in Muslim countries. This study contributes by clarifying the factors in the decision-making process and elucidating perspectives about TOP in a Muslim country with a unique status: Turkey.

When New Life Meets Death: Three Hermeneutic Case Studies From Switzerland

Pregnant women in Switzerland expect safe and healthy birth outcomes for themselves and their babies. However, in 2018, 691 died in infancy with gaps identified in the provision of services to parents in such circumstances. Our study aims to illustrate these gaps and how, from participants’ perspectives, they were addressed. A hermeneutic method was employed to analyze three cases: one from each major language region was via primary health-care providers. A thematic analysis was carried out with individual participants followed by a cross-case comparison which showed a hermeneutic of rupture, the juxtaposition of time and reshaping the family. This article shows the unique journeys experienced by parents whose baby dies before or shortly after birth in one country where neither the language nor experience is shared. The derivation of three hermeneutic themes may resonate with other parents or health professionals.

Perinatal Palliative Care Birth Planning as Advance Care Planning

Purpose of Review: A significant number of pregnancies are complicated by a fetus with a life-limiting diagnosis. As diagnoses are made earlier in the pregnancy, families experience anticipatory grief and are faced with navigating goals of care for a baby that has yet to be born. With the support of the care team, families can begin to grieve, plan, and make meaningful memories during the duration of the pregnancy, the birth of their baby, and life of the child. Creating a palliative care birth plan, which expands beyond the traditional concept for delivery planning to include prenatal, perinatal, and neonatal care has become an important method for parents to process the diagnosis, for parents to document their wishes, and for members of the care team to communicate with the goal of supporting and enhancing the experience of the family. This articles reviews recent and relevant literature on the importance of birth planning and the role of perinatal palliative care when a life-limiting fetal diagnosis is made. Recent Findings: The process of birth planning is an important component of perinatal palliative care. Through this process, families can express their fears, values, hopes, and wishes. It also offers an opportunity for providers to communicate these wishes for the remainder of the pregnancy, the delivery, birth, and time afterwards. This has been demonstrated to decrease maternal stress and promote family centered care. Summary: Perinatal birth planning is an important component of perinatal palliative care when a fetus has a life-limiting diagnosis. The process of birth planning can be supportive and therapeutic as well as an important communication tool. With multiple practices and designs of perinatal palliative care programs, there are no standard tools even though important components have been identified. Ultimately, the strategies outlined here can be used as advance care planning tools.

Parental decision-making following a prenatal diagnosis that is lethal, life-limiting, or has long term implications for the future child and family: a meta-synthesis of qualitative literature

BACKGROUND

Information on the factors influencing parents' decision-making process following a lethal, life-limiting or severely debilitating prenatal diagnosis remains deficient. A comprehensive systematic review and meta-synthesis was conducted to explore the influencing factors for parents considering termination or continuation of pregnancy following identification of lethal, life-limiting or severely debilitating fetal abnormalities.

METHODS

Electronic searches of 13 databases were conducted. These searches were supplemented by hand-searching Google Scholar and bibliographies and citation tracing. Thomas and Harden's (2008) thematic synthesis method was used to synthesise data from identified studies.

RESULTS

Twenty-four papers were identified and reviewed, but two papers were removed following quality assessment. Three main themes were identified through systematic synthesis. Theme 1, entitled 'all life is precious', described parents' perception of the importance of the fetus' life, a fatalistic view of their situation alongside moral implications as well as the implications decisions would have on their own life, in consideration of previous life experiences. Theme 2 ('hope for a positive outcome') contained two sub-themes which considered the parent's own imagined future and the influence of other people's experiences. Finally, Theme 3 ('a life worth living') presented three sub-themes which may influence their parental decision-making: These described parental consideration of the quality of life for their unborn child, the possibility of waiting to try for another pregnancy, and their own responsibilities and commitments.

CONCLUSION

The first review to fully explore parental decision-making process following lethal, life-limiting, or severely debilitating prenatal diagnosis provided novel findings and insight into which factors influenced parents' decision-making process. This comprehensive and systematic review provides greater understanding of the factors influential on decision-making, such as hope, morality and potential implications on their own and other's quality of life, will enable professionals to facilitate supported decision-making, including greater knowledge of the variables likely to influence parental choices.

Ethical, social, and cultural issues related to clinical genetic testing and counseling in low- and middle-income countries: a systematic review

PURPOSE

We performed a systematic review of the ethical, social, and cultural issues associated with delivery of genetic services in low- and middle-income countries (LMICs).

METHODS

We searched 11 databases for studies addressing ethical, social, and/or cultural issues associated with clinical genetic testing and/or counselling performed in LMICs. Narrative synthesis was employed to analyze findings, and resultant themes were mapped onto the social ecological model (PROSPERO #CRD42016042894).

RESULTS

After reviewing 13,308 articles, 192 met inclusion criteria. Nine themes emerged: (1) genetic counseling has a tendency of being directive, (2) genetic services have psychosocial consequences that require improved support, (3) medical genetics training is inadequate, (4) genetic services are difficult to access, (5) social determinants affect uptake and understanding of genetic services, (6) social stigma is often associated with genetic disease, (7) family values are at risk of disruption by genetic services, (8) religious principles pose barriers to acceptability and utilization of genetic services, and (9) cultural beliefs and practices influence uptake of information and understanding of genetic disease.

CONCLUSION

We identified a number of complex and interrelated ethical, cultural, and social issues with implications implications for further development of genetic services in LMICs.

Diagnosis of a severe congenital anomaly: A qualitative analysis of parental decision making and the implications for healthcare encounters

Objective

To explore parental decision making following diagnosis of a severe congenital anomaly, and implications for healthcare encounters.

Design

Qualitative semi‐structured interviews with 38 parents‐to‐be were collated and triangulated with data generated from consultation recordings.

Analysis

Data were analysed using a constant comparative‐based approach.

Setting

Recruitment was undertaken across four fetal medicine sites in two tertiary referral trusts.

Participants

Parents‐to‐be whose pregnancy was suspected or diagnosed as being affected by a severe congenital anomaly. This sample was purposive to include known factors affecting the decision to terminate or continue the affected pregnancy.

Findings

In trying to make a decision about how to proceed with their pregnancy, parents‐to‐be typically had to work hard to negotiate multiple uncertainties around the diagnosis and prognosis of the suspected anomaly. This was influenced by parents’ capacity to cope with uncertainty and the way in which uncertainty was managed by the clinical team. This negotiation of uncertainty was enacted within a fluid, nonlinear three‐phase process: “information seeking,” reflecting the way parents‐to‐be face the uncertainty associated with a fetal diagnosis and associated prognosis; “implications,” where consideration is given to future consequences of the decision; and “decision making,” which reflects the way in which the decision is made (head‐ or heart‐led). Spectrums of responses were apparent within each phase.

Conclusions

This study provides important insights into how parents‐to‐be make decisions following diagnosis or suspicion of a severe congenital anomaly. The impact of these on healthcare encounters is discussed, alongside recommendations for clinical practice.

Attitude toward Prenatal Testing and Termination of Pregnancy among Health Professionals and Medical Students in Saudi Arabia

This study was aimed at assessing the attitude of health care professionals in Jeddah city toward prenatal diagnosis (PND) and termination of pregnancy (TOP). A cross-sectional study was conducted, and the participants completed a self-administered questionnaire. Approximately 82% of participants showed a consistent trend of accepting PND when appropriate, and 47.5% of the respondents were in favor of TOP if the fetus had a severe disease. Compared with men (69.3%), a significantly greater number of women (88%) accepted to have PND. The most acceptable prenatal diagnostic tests in the study were invasive techniques as most of the participants thought that noninvasive tests were nonspecific.

A Qualitative Study of Factors Influencing Decision-Making after Prenatal Diagnosis of down Syndrome

Previous research has identified twenty-six factors that may affect pregnancy management decisions following prenatal diagnosis of DS; however, there is no consensus about the relative importance or effects of these factors. In order to better understand patient decision-making, we conducted expansive cognitive interviews with nine former patients who received a prenatal diagnosis of DS. Our results suggest that patients attached unique meanings to factors influencing decision-making regardless of the pregnancy outcome. Nineteen of the twenty-six factors previously studied and four novel factors (rationale for testing, information quality, pregnancy experience, and perception of parenting abilities and goals) were found to be important to decision-making. We argue that qualitative studies can help characterize the complexity of decision-making following prenatal diagnosis of DS.

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.

Breaking bad news in prenatal medicine: a literature review

BACKGROUND

The diagnosis of a fetal anomaly in perinatal medicine forces expectant parents and healthcare providers to face the difficult process of breaking bad news.

OBJECTIVES

This exploratory literature review was aimed at providing a medical and psychological view of the psychological experience in expectant parents and physicians in the context of prenatal diagnosis of a fetal anomaly.

METHOD

An exploratory search of PubMed and PsycINFO/PsycARTICLES databases performed by an interdisciplinary team composed of a physician and psychologists. Search terms were: prenatal diagnosis AND bad news; prenatal diagnosis AND psychological consequences; prenatal diagnosis AND psychological sequelae; prenatal diagnosis AND fetal abnormality. The processing of selected articles followed a standardised five-step procedure.

RESULTS

A total of 860 articles were screened of which 32 were retained for analysis. Four main themes emerged from the explanatory content analysis: (1) parents' subjective experience; (2) physicians' subjective experience; (3) encounters between expectant parents and professionals; and (4) ethical challenges in breaking bad news in prenatal medicine.

CONCLUSION

Expectant parents go through a complex and multidimensional experience when the diagnosis of a fetal anomaly is disclosed. Simultaneously, physicians consider breaking bad news as a very stressful event and are poorly prepared in this regard. A better knowledge of factors underlying psychological adjustment of the parental dyad and on the subjective experience of physicians delivering these diagnoses could enable better adaptation for both patients and professionals.

Parental decisions following prenatal diagnosis of chromosomal abnormalities: implications for genetic counseling practice in Japan

Parental decision-making to terminate or continue a pregnancy was studied after prenatal diagnosis of a chromosome aneuploidy among a sample of patients around the city of Nagoya, Japan. A total of 1,051 amniocentesis cases at 15-18 weeks of gestation were analyzed. Of these, 60 cases of chromosomal anomalies with aneuploidies were diagnosed by conventional cytogenetic analysis. Of the 45 diagnoses of autosomal chromosome aneuploidies, pregnancy was terminated in 93.3 % of the cases. Of the 15 cases diagnosed with sex chromosome aneuploidy, pregnancy was terminated in 46.7 %. Differences in parental decisions with respect to maternal age, gestational week at diagnosis, number of pregnancies per individual and existing number of children were not significant in patients diagnosed either with autosomal or sex chromosome aneuploidy. The findings indicate that when diagnosed with a chromosome aneuploidy in which a severe prognosis was expected, most couples decided to terminate the pregnancy in Japan. Implications of these findings for expanding the profession of genetic counseling are discussed and research recommendations are provided.

Parental decision-making for medically complex infants and children: an integrated literature review

BACKGROUND

Many children with life-threatening conditions who would have died at birth are now surviving months to years longer than previously expected. Understanding how parents make decisions is necessary to prevent parental regret about decision-making, which can lead to psychological distress, decreased physical health, and decreased quality of life for the parents.

OBJECTIVE

The aim of this integrated literature review was to describe possible factors that affect parental decision-making for medically complex children. The critical decisions included continuation or termination of a high-risk pregnancy, initiation of life-sustaining treatments such as resuscitation, complex cardiothoracic surgery, use of experimental treatments, end-of-life care, and limitation of care or withdrawal of support.

DESIGN

PubMed, Cumulative Index of Nursing and Allied Health Literature, and PsycINFO were searched using the combined key terms 'parents and decision-making' to obtain English language publications from 2000 to June 2013.

RESULTS

The findings from each of the 31 articles retained were recorded. The strengths of the empirical research reviewed are that decisions about initiating life support and withdrawing life support have received significant attention. Researchers have explored how many different factors impact decision-making and have used multiple different research designs and data collection methods to explore the decision-making process. These initial studies lay the foundation for future research and have provided insight into parental decision-making during times of crisis.

CONCLUSIONS

Studies must begin to include both parents and providers so that researchers can evaluate how decisions are made for individual children with complex chronic conditions to understand the dynamics between parents and parent-provider relationships. The majority of studies focused on one homogenous diagnostic group of premature infants and children with complex congenital heart disease. Thus comparisons across other child illness categories cannot be made. Most studies also used cross-sectional and/or retrospective research designs, which led to researchers and clinicians having limited understanding of how factors change over time for parents.

Experts' opinions on the benefit of an incidental prenatal diagnosis of sex chromosomal aneuploidy: a qualitative interview survey

OBJECTIVE

Incidental findings in prenatal diagnostic testing may or may not have clear prognostic significance for the phenotype. We studied experts' opinions of the benefit and disadvantage of an incidental prenatal diagnosis of a sex chromosomal aneuploidy (SCA).

METHODS

We interviewed 16 experts in the field of counseling and treatment of people with SCA and asked 13 clinical geneticists and genetic associates about the clinical relevance of an incidental prenatal diagnosis of SCA.

RESULTS

Most of the experts and clinical geneticists (87.5% and 76.9%, respectively) stated that an incidental prenatal diagnosis of SCA was a benefit for the child and the parents. They acknowledged the possibility of parental decisions to terminate pregnancy. Expert options in screening, training, and treatment of health, behavior, and fertility problems increase with an early diagnosis of SCA.

CONCLUSION

Most experts favored an incidental prenatal diagnosis of SCA despite the complex counseling issues and their acknowledgment of possible parental decisions to terminate pregnancy. They believed the benefits greatly outweigh the disadvantages.

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.

Non-invasive prenatal screening of fetal sex chromosomal abnormalities: perspective of pregnant women

OBJECTIVE

To study whether pregnant women would like to be informed if sex chromosomal abnormalities (SCA) were suspected with the non-invasive prenatal diagnosis of fetal Down syndrome (the NIFTY) test.

METHODS

Two hundred and one patients carried a singleton pregnancy requesting the NIFTY test were invited to give their preferences if there was suspicion of SCA by the NIFTY test.

RESULTS

Over 93.5% were ethnic Chinese, with a mean age of 36. Prior Down screening was positive in 66 (32.8%). Over 50% of subjects considered SCA to be better in terms of disability compared to Down syndrome, and only 5.2% considered SCA to be worse. Yet, the majority (198, 98.5%) indicated that they wanted to be informed if there was suspicion of SCA. Of whom 34.8% would have an amniocentesis for confirmation, while 57.1% were not certain, indicating the possibility of accepting these conditions.

CONCLUSION

Besides screening Down syndrome by NIFTY, most pregnant women would also like to be informed if there was suspicion of SCA. Those screened positive should be counseled by those with experience in genetics to avoid unnecessary pregnancy termination.

Reproductive decisions after fetal genetic counselling

A broad range of testing modalities for fetal genetic disease has been established. These include carrier screening for single-gene mutations, first-trimester and second-trimester screening for chromosome abnormalities and open neural-tube defects, prenatal diagnosis by means of chorionic villus sampling and amniocentesis, and preimplantation genetic diagnosis. Reproductive decisions before and after fetal genetic counselling represent the culmination of a dynamic interaction between prospective parents, obstetrician and genetic counsellor. The decision to undergo genetic testing before and after genetic counselling is influenced by a host of interrelated factors, including patient-partner and family relationships, patient-physician communication, societal mores, religious beliefs, and the media. Because of the complexity of personal and societal factors involved, it is not surprising that genetic counselling concerning reproductive decision-making must be individualised. A limited number of principles, guidelines and standards apply when counselling about testing for fetal genetic disease. These principles are that genetic counselling should be non-directive and unbiased and that parental decisions should be supported regardless of the reproductive choice. A critical responsibility of the obstetrician and genetic counsellor is to provide accurate and objective information about the implications, advantages, disadvantages and consequences of any genetic testing applied to prospective parents and their fetuses. These principles and responsibilities will be tested as newer technologies, such as array comparative genome hybridisation, non-invasive prenatal diagnosis and sequencing of the entire genome are introduced into the field of reproductive genetics and become routine practice.

Decision to abort after a prenatal diagnosis of sex chromosome abnormality: a systematic review of the literature

We performed a systematic review of factors affecting parental decisions to continue or terminate a pregnancy after prenatal diagnosis of a sex chromosome abnormality, as reported in published studies from 1987 to May 2011. Based on the Matrix Method for systematic reviews, 19 studies were found in five electronic databases, meeting specific inclusion/exclusion criteria. Abstracted data were organized in a matrix. Alongside the search for factors influencing parental decisions, each study was judged on its methodological quality and assigned a methodological quality score. Decisions either to terminate or to continue a sex chromosome abnormality-affected pregnancy shared five similar factors: specific type of sex chromosome abnormality, gestational week at diagnosis, parents' age, providers' genetic expertise, and number of children/desire for (more) children. Factors unique to termination decisions included parents' fear/anxiety and directive counseling. Factors uniquely associated with continuation decisions were parents' socioeconomic status and ethnicity. The studies' average methodological quality score was 10.6 (SD = 1.67; range, 8-14). Findings from this review can be useful in adapting and modifying guidelines for genetic counseling after prenatal diagnosis of a sex chromosome abnormality. Moreover, improving the quality of future studies on this topic may allow clearer understanding of the most influential factors affecting parental decisions.
