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

Evaluating pregnancy termination decisions for fetal anomalies: a retrospective study in a tertiary referral center

OBJECTIVE

The aim of this study was to examine the factors that influence pregnancy termination due to fetal anomalies, regardless of gestational age, within the legal framework of Turkey.

METHODS

This retrospective study was conducted between January 2021 and July 2023 at a tertiary perinatology center to analyze patients undergoing pregnancy termination. The process involved multidisciplinary evaluations and informed consent, resulting in 326 pregnancy terminations, categorized by gestational timing.

RESULTS

Of the 326 patients studied, 219 opted for terminations. Gestational week at diagnosis significantly influenced the decision to terminate, with fetal anomalies being the primary indication. Chromosomal abnormalities accounted for 15.9% of the cases, while structural anomalies and maternal disorders accounted for 84.1% and structural malformations accounted for 84.1% of the cases. Late terminations (≥23 weeks) accounted for 30% of cases and required complex procedures.

CONCLUSION

The findings of this study indicate that maternal demographic factors have a limited impact on termination decisions. Early diagnosis of fetal anomalies is crucial for informed decision-making and emotional support, and the psychological consequences of late termination highlight the need for maternal support. Obstetricians play a vital role in facilitating early intervention. This study underscores the complex medical, ethical, and psychological aspects of pregnancy termination due to fetal anomalies. It emphasizes the importance of a holistic approach, considering medical, ethical, and psychological factors and the crucial role of healthcare professionals in supporting families during this challenging process.

Sociodemographic profile associated with congenital heart disease among infants <1 year old

PURPOSE

Congenital heart disease affects thousands of newborns each year in the United States. Previous United States-based research has explored how sociodemographic factors may impact health outcomes in infants with congenital heart disease; however, their impact on the incidence of congenital heart disease is unclear. We explored the sociodemographic profile related to congenital heart disease to help address health disparities that arise from race and social determinants of health. Defining the sociodemographic factors associated with congenital heart disease will encourage implementation of potential preventative measures.

DESIGN AND METHODS

We conducted a secondary analysis of longitudinally collected data comparing 39 infants with congenital heart disease and 30 healthy controls. We used a questionnaire to collect sociodemographic data. Pearson's chi-square test/Fisher's exact tests analyzed the associations among different sociodemographic factors between infants with congenital heart disease and healthy controls.

RESULTS

We found a statistically significant difference in maternal education between our 2 groups of infants (p = 0.004).

CONCLUSION

Maternal education was associated with congenital heart disease. Future studies are needed to further characterize sociodemographic factors that may predict and impact the incidence of congenital heart disease and to determine possible interventions that may help decrease health disparities regarding the incidence of congenital heart disease.

PRACTICE IMPLICATIONS

Understanding the associations between maternal sociodemographic factors and infant congenital heart disease would allow clinicians to identify mothers at higher risk of having an infant with congenital heart disease.

The impact of early diagnosis of fetal single-ventricle cardiac defects on reproductive choices

BACKGROUND

Congenital heart defects are the most common fetal anomaly. Congenital heart defects with single-ventricle cardiac defects have high mortality rates, and in pregnancies diagnosed with this condition, patients are often offered termination of pregnancy as an option.

OBJECTIVE

This study aimed to investigate the relationship between gestational age at diagnosis and reproductive choices in fetuses diagnosed with single-ventricle cardiac defects.

STUDY DESIGN

This was a retrospective single-center cohort study in which 158 patients with a fetal diagnosis of single-ventricle cardiac defects were reviewed. Cases were categorized as isolated or complex. Complex cases included fetuses with single-ventricle cardiac defects in addition to other fetal extracardiac anomalies or chromosomal abnormalities.

RESULTS

A total of 158 patients were diagnosed with single-ventricle cardiac defects during the study period. Of those patients, 37 (23.4%) underwent termination of pregnancy, 113 (71.5%) delivered, and 8 (5.1%) had an intrauterine fetal demise. Gestational age at diagnosis and race were significant predictors of the termination decision. The median gestational age at diagnosis was earlier in the termination of pregnancy group (20.4 vs 23.6 weeks; P<.001). Pregnancies complicated by single-ventricle cardiac defects diagnosed in early gestation (11 0/7 to 14 5/7 weeks of gestation) were more likely to be terminated than pregnancies complicated by single-ventricle cardiac defects diagnosed in middle gestation (15 0/7 to 27 5/7 weeks of gestation) and late gestation (≥28 weeks of gestation) (54.2% vs 23.2% and 2.9%; P<.001). Earlier gestational age at diagnosis was correlated with earlier gestational age at termination (r=0.92; P<.001).

CONCLUSION

Termination of pregnancy was more common when the single-ventricle cardiac defect was diagnosed earlier in pregnancy. This could be explained by the fact that early diagnoses allow parents to make deliberate and informed decisions.

Impact of interdisciplinary counselling for parental decision-making in cases of pregnancies with prenatally diagnosed CHD

INTRODUCTION

Parental counselling after antenatal diagnosis of a congenital heart defect requires a high degree of professional and emotional competence and ultimately a sense of responsibility on the part of the consulting physicians. However, little is known about parents` perceptions and evaluation of these consultations.

MATERIAL/METHODS

Survey on 425 women who received interdisciplinary counselling after antenatal diagnosis of a complex fetal congenital heart defect in a specialized prenatal outpatient clinic with an affiliated paediatric heart centre. Two questionnaires were used to retrospectively evaluate the parental perception and impact on counselling, particularly on decision-making. Questionnaires differed between women conceiving the child and women who terminated the pregnancy.

RESULTS

400 women continued, 25 women terminated the pregnancy after diagnosis and counselling. Good quality of life was reported for 68% of the children, 15% died postnatally in the further course. 95% rated the counselling as good or very good regardless of the child´s outcome. 73% described the counselling as highly important for their subsequent decision. The possibility of termination of pregnancy was discussed with 37% of the respondents, 22% of them found it outrageous or very distressing. Of all respondents, one woman would have made a different decision regarding continuation of the pregnancy in retrospect.

CONCLUSION

Retrospectively, parents rate prenatal counselling extremely positively, irrespective of the severity of the child´s heart defect. It can be assumed that the consistent joint interdisciplinary consultation and the high reputation of the cooperating heart centre have had an influence on the below-average rate of termination of pregnancy.

The Role of Nurses in Fetal Cardiology Programs: An Integrative Review

BACKGROUND

Fetal cardiology programs are evolving quickly and include multiple interdisciplinary health care professionals whose roles could benefit from clear definition. Nurses provide an essential function in this field; however, descriptions or definitions of nursing practice, education and knowledge requirements, and responsibilities are limited and vary across institutions and disciplines.

PURPOSE

To conduct an integrative review summarizing the literature to determine the role of nurses in fetal cardiology programs.

METHODS

We conducted an integrative review as per Whittemore and Knafl's (2005) methodology of current literature to reveal strengths and opportunities in describing nursing practice as fetal cardiology nurses. The search strategy included five electronic databases: CINAHL, Medline, PsycINFO, Web of Science, and Google Scholar. Peer-reviewed English-language articles discussing nursing practices in fetal cardiology published between 2015 and 2022 were selected. Data extraction and analysis were completed on a final sample of 26 articles.

RESULTS

Four themes were identified on fetal cardiac nursing practice from nursing and medical perspectives: multidisciplinary key team member, psychosocial family support and counselor, coordinator or navigator, and role description.

CLINICAL IMPLICATIONS

More discussion in the literature is needed to better understand and define fetal cardiac nursing practice. Although most experts agree nurses are an important member of the interdisciplinary fetal cardiology team, their roles and educational requirements are poorly described and defined. Quality metrics and benchmarks are needed to ensure safe and effective fetal cardiology care.

Sociodemographic Profile Associated with Congenital Heart Disease among Infants Less than 1 Year Old

Background

Congenital heart disease (CHD) affects thousands of newborns each year in the United States (US). Infants born with CHD have an increased risk of adverse health outcomes compared to healthy infants. These outcomes include, but are not limited to, neurodevelopmental, surgical, and mortality-related outcomes. Previous US-based research has explored how sociodemographic factors may impact these health outcomes in infants with CHD; however, their impact on the risk of CHD is unclear. This study aims to explore the sociodemographic profile related to CHD to help address health disparities that arise from race and social determinants of health. Defining the sociodemographic factors associated with CHD will encourage policy change and the implementation of preventative measures.

Methods

This study is a secondary analysis of longitudinally collected data. We compared infants with CHD and healthy controls. We used a questionnaire to collect sociodemographic data. Pearson's chi-square test/Fisher's exact tests analyzed the associations among different sociodemographic factors between infants with CHD and healthy controls.

Results

We obtained sociodemographic factors from 30 healthy control infants and 39 infants with CHD. We found a statistically significant difference in maternal education between our 2 groups of infants (p=0.004).

Conclusion

Maternal education is associated with CHD. Future studies are needed to further characterize sociodemographic factors that may predict and impact the risk of CHD and to determine possible interventions that may help decrease health disparities regarding the risk of CHD.

Impact of rural residence and low socioeconomic status on rate and timing of prenatal detection of major congenital heart disease in a jurisdiction of universal health coverage

OBJECTIVE

Socioeconomic status (SES) and distance of residence from tertiary care may impact fetal detection of congenital heart disease (CHD), partly through reduced access to and quality of obstetric ultrasound screening. It is unknown whether SES and remoteness of residence (RoR) affect prenatal detection of CHD in jurisdictions with universal health coverage. We examined the impact of SES and RoR on the rate and timing of prenatal diagnosis of major CHD within the province of Alberta in Canada.

METHODS

In this retrospective study, we identified all fetuses and infants diagnosed with major CHD in Alberta, from 2008 to 2018, that underwent cardiac surgical intervention within the first year after birth, died preoperatively, were stillborn or underwent termination. Using maternal residence postal code and geocoding, Chan SES index quintile, geographic distance from a tertiary-care fetal cardiology center and the Canadian Index of Remoteness (IoR) were calculated. Outcome measures included rates of prenatal diagnosis and diagnosis after 22 weeks' gestation. Risk ratios (RR) were calculated using log-binomial regression and stratified by rural (≥ 100 km from tertiary care) or metropolitan (< 100 km from tertiary care) residence, adjusting for year of birth and the obstetric ultrasound screening view in which CHD would most likely be detected (four-chamber view; outflow-tract view; three-vessel or three-vessels-and-trachea or non-standard view; septal view).

RESULTS

Of 1405 fetuses/infants with major CHD, prenatal diagnosis occurred in 814 (57.9%). Residence ≥ 100 km from tertiary care (adjusted RR, 1.19; 95% CI, 1.05-1.34) and higher IoR (adjusted RR, 1.9; 95% CI, 1.1-3.3) were associated with missed prenatal diagnosis of major CHD. Similarly, residence ≥ 100 km from tertiary care (adjusted RR, 1.41; 95% CI, 1.22-1.62) and higher IoR (adjusted RR, 3.6; 95% CI, 2.2-8.2) were associated with prenatal diagnosis after 22 weeks. Although adjusted and unadjusted analyses showed no association between Chan SES index quintile and prenatal-diagnosis rate overall nor for residence in rural areas, in metropolitan regions, lower SES quintiles were associated with missed prenatal diagnosis (quintile 1: RR, 1.24; 95% CI, 1.02-1.50) and higher risk of diagnosis after 22 weeks' gestation (quintile 1: RR, 1.46; 95% CI, 1.10-1.93; quintile 2: RR, 1.66; 95% CI, 1.24-2.23).

CONCLUSIONS

Despite universal healthcare, rural residence in Alberta is associated with lower rate of prenatal diagnosis of major CHD and higher risk of late prenatal diagnosis (≥ 22 weeks). Within metropolitan regions, lower SES impacts negatively prenatal-diagnosis rate and timing. © 2022 International Society of Ultrasound in Obstetrics and Gynecology.

Vigilance in the Decision-Making Process Regarding Termination of Pregnancy Following Prenatal Diagnosis of Congenital Heart Disease-Application of the 'Conflict Decision-Making Model'

The decision-making process regarding termination of pregnancy following prenatal diagnosis of congenital heart disease is a stressful experience for future parents. Janis and Mann’s conflict decision-making model describes seven ideal stages that comprise vigilant information-gathering as an expression of the qualitative decision-making process. In our study, we attempted to determine whether parents who face the decision regarding termination of pregnancy undertake a qualitative decision-making process. Data were collected over 2-year period using structural questionnaires. The sample consisted of two hundred forty participants; sixty-nine (28.75%) declared that their decision was to terminate the pregnancy. A significant difference in the quality of the decision-making score was noted between parents who decided to continue with the pregnancy vs. parents who opted for termination (mean score of 10.15 (5.6) vs. 18.51 (3.9), respectively, p < 0.001). Sixty-two (90%) participants within the termination of pregnancy group went through all seven stages of vigilant decision-making process and utilized additional sources for information and consultation. Parents who decided to continue with the pregnancy made swift decisions, often without considering the negative and positive outcomes; this decision-making pattern is considered non-vigilant and ineffective. Identification of future parents at risk of going through an ineffective decision-making process may help health professionals to determine the best way to provide them with information and support.

Prenatal diagnosis of significant congenital heart disease and elective termination of pregnancy in Nevada

OBJECTIVE

We investigated the relationship between prenatal detection of significant congenital heart disease and elective termination of pregnancy over time in Nevada.

METHODS

We identified those prenatally or post-natally diagnosed with significant congenital cardiovascular malformations in Nevada with birth dates or estimated delivery dates between July 2012 and June 2021.

RESULTS

We identified 1246. Of 1246, 69 underwent fetal demise, 42 had elective termination, and 1135 were live-born. Of the 1135 live-born, 1090 had prenatal care, of which 718 (66%) overall had a prenatal diagnosis of significant congenital heart disease. However, prenatal detection statistically significantly increased over time from 45 to 82%, p = .00001. Termination of pregnancy averaged 10% of those identified within the legal timeframe, and the rate did not statistically significantly increase with increasing prenatal detection rates, p = .56. Of the 42 undergoing elective termination, 23 (55%) had syndromes or comorbidities vs. 280 (25%) of the 1135 live-births, p = .0003.

CONCLUSIONS

In Nevada, despite a statistically significant increase in prenatal detection of significant congenital heart disease over time, termination of pregnancy rates did not increase. Nevertheless, those undergoing elective termination were more likely to have associated syndromes or comorbidities.
