Perinatal management of trisomy 18: a survey of obstetricians in Australia, New Zealand and the UK

Causes of death in individuals with trisomy 18 after the first year of life

Mortality in individuals with trisomy 18 has significantly decreased over the past 20 years, but there is scant literature addressing the prognosis and cause of death in individuals with trisomy 18 and survival past the first year of life (YOL). This study analyzed factors associated with mortality and cause of death in a retrospective cohort of 174 individuals with trisomy 18 and survival past the first YOL, the largest such series to date. Data were collected via retrospective survey of parents of affected individuals. Prenatal diagnosis of trisomy 18; postnatal respiratory distress; maternal age > 35 years; birthweight <2000 g; brain and spinal cord defect(s); atrial and/or ventricular septal defect(s); inability to feed orally without medical assistance; and failure to meet sitting and rolling milestones were associated with mortality in this sample. Cause of death was compared between our cohort of individuals with trisomy 18 and existing literature on those with mortality before the first YOL. Individuals with trisomy 18 with mortality after the first YOL demonstrated a predominance of infectious (n = 10/22) and postoperative (n = 6/22) contributing causes of death, in contrast to the existing literature, which shows a predominance of cardiopulmonary causes of death (e.g., cardiopulmonary arrest, pulmonary hypertension). These findings demonstrate that individuals with trisomy 18 and survival past the first YOL have unique medical needs, but further research is needed to develop clinical guidelines for this growing population.

Conducta médica frente al diagnóstico prenatal de trisomía 18: ¿se aproxima un cambio de paradigma?

El objetivo del trabajo es analizar dos conductas médicas opuestas en la vida prenatal de los niños con trisomía 18: el aborto y los cuidados paliativos perinatales. Se realizó una búsqueda bibliográfica en PubMed a partir de los términos “trisomy 18”, “abortion” y “palliative care”. Actualmente, están cambiando las conductas médicas dirigidas a los niños nacidos con trisomía 18, debido a que ya no se la considera una enfermedad incompatible con la vida. Este cambio de paradigma en la conducta médica posnatal debería reflejarse en la conducta prenatal, para ofrecer a los padres alternativas distintas al aborto. Los cuidados paliativos fetales y perinatales constituyen una respuesta ética válida para el tratamiento de niños con trisomía 18.

Factors Influencing Physician Prognosis: A Scoping Review

Introduction. Prognosis is an essential component of informed consent for medical decision making. Research shows that physicians display discrepancies in their prognostication, leading to variable, inaccurate, optimistic, or pessimistic prognosis. Factors driving these discrepancies and the supporting evidence have not been reviewed systematically. Methods. We undertook a scoping review to explore the literature on the factors leading to discrepancies in medical prognosis. We searched Medline (Ovid) and Embase (Ovid) databases for peer-reviewed articles from 1970 to 2017. We included articles that discussed prognosis variation or discrepancy and where factors influencing prognosis were evaluated. We extracted data outlining the participants, methodology, and prognosis discrepancy information and measured factors influencing prognosis. Results. Of 4,723 articles, 73 were included in the final analysis. There was significant variability in research methodologies. Most articles showed that physicians were pessimistic regarding patient outcomes, particularly in early trainees and acute care specialties. Accuracy rates were similar across all time periods. Factors influencing prognosis were clustered in 4 categories: patient-related factors (such as age, gender, race, diagnosis), physician-related factors (such as age, race, gender, specialty, training and experience, attitudes and values), clinical situation-related factors (such as physician-patient relationship, patient location, and clinical context), and environmental-related factors (such as country or hospital size). Discussion. Obtaining accurate prognostic information is one of the highest priorities for seriously ill patients. The literature shows trends toward pessimism, especially in early trainees and acute care specialties. While some factors may prove difficult to change, the physician's personality and psychology influence prognosis accuracy and could be tackled using debiasing strategies. Exposure to long-term patient outcomes and a multidisciplinary practice setting are environmental debiasing strategies that may warrant further research.

Highlights

Literature on discrepancies in physician's prognostication is heterogeneous and sparse.Literature shows that physicians are mostly pessimistic regarding patient outcomes.Literature shows that a physician's personality and psychology influence prognostic accuracy and could be improved with evidence-based debiasing strategies.Medical specialty strongly influences prognosis, with specialties exposed to acutely ill patients being more pessimistic, whereas specialties following patients longitudinally being more optimistic.Physicians early in their training were more pessimist than more experienced physicians.

Ethics education in pediatrics: Implementation and evaluation of an interactive online course for medical students

INTRODUCTION

The COVID-19 pandemic has catalyzed the development of online learning formats in virtually all areas of medical education. In pediatric ethics, online learning may not only substitute but also offer specific advantages over traditional classroom teaching. Many pediatricians rate their ethics education as poor and medical ethics education lacks evaluation, especially regarding the students' needs. The aim of this project was to implement and evaluate a novel interactive distance learning approach to engage medical students in pediatric ethics education.

METHODS

An online ethics course was designed and delivered between May and June 2020. Core item of this course was a moderated, written forum discussion spanning several days. Evaluation was mixed methods. We evaluated the effectiveness of the course in terms of quality of the learning environment with a particular focus on relevance to students as well as interactive learning and reflective thinking. The Constructivist On-Line Learning Environment Survey (COLLES) was used to evaluate six different domains of the course. Data are presented as mean (standard deviation [SD]). The respective score range is 1-5, whereby a score of 4 or 5 means that the participants indicated the corresponding item as frequently or almost always present.

RESULTS

Responses were available from 104 (78.3%) of the 133 participating students. "Relevance" yielded a score of 4.17 (0.83), "reflective thinking" a score of 4.22 (0.83). "Interactivity" was scored 3.76 (0.99) and "tutor support" 4.72 (0.53). "Peer support" and "interpretation" scored 3.87 (0.98) and 4.49 (0.60), respectively. In qualitative analysis, students particularly valued the structure of the course, the relevance for their professional practice, their active participation and the incentive to reflective thinking. Students also indicated that this was an innovative and exciting format, which fills a current educational gap and should hence be continued beyond the pandemic.

CONCLUSION

In conclusion, students actively engaged in online learning and perceived this ethics course as highly relevant for their professional practice.

Survival outcomes of very low birth weight infants with trisomy 18

Trisomy 18 (T18) is one of the most commonly diagnosed aneuploidies leading to poor survival outcome. However, little is known about the dual risk of T18 and very low birth weight (VLBW, weighing <1500 g at birth). We aimed to investigate the survival and clinical features of VLBW infants with T18. In this observational cohort study, infants with T18 admitted to the neonatal intensive care unit in Kyushu University Hospital from 2000 to 2019 were eligible. Among 30 infants with T18 who were enrolled as study participants, 11 (37%) were born with VLBW. VLBW infants had lower gestational age (34.4 vs. 39.4 weeks, p < 0.01) and a higher incidence of esophageal atresia (64% vs. 11%, p < 0.01) than non-VLBW infants. The proportions of patients who underwent any surgery (55% vs. 5%, p < 0.01) and positive pressure ventilation (82% vs. 32%, p = 0.02) were higher in VLBW than non-VLBW infants. One-year overall survival rate (45% vs. 26%, p = 0.32 by log-rank test) did not differ between the two groups. In conclusion, being born at VLBW may not be fatal for infants with T18 undergoing active interventions.

Attitudes of clinicians toward cardiac surgery and trisomy 18

Trisomy 18 is an autosomal trisomy condition characterized by minor to major birth defects, severe disabilities, and high rates of pre- and postnatal mortality. Interventions for these infants have traditionally been withheld with focus instead on palliative support. The issues and attitudes surrounding corrective surgery of congenital heart defects, which is a birth defect that occurs in approximately 90% of infants with trisomy 18, is of our study's interest as recent literature has indicated that cardiac surgery is being performed and may lead to improved survival compared to palliative care. Thus, our study aimed to describe clinician attitudes toward cardiac surgery and trisomy 18. We surveyed 378 clinicians from multiple specialties, including genetic counselors, involved in the pre- and postnatal care of infants with trisomy 18. Descriptive statistics were performed to describe all clinicians' responses, and a secondary analysis with stratifications by clinician type was also performed. Forty-eight percent (n = 378) of clinicians felt it was appropriate to discuss the option of cardiac surgery. Ethical concerns and insufficient outcome data were the most agreed upon reasons for not offering cardiac surgery. Trisomy 18 not being uniformly lethal and expressed parental wishes were the most agreed upon justifications for offering surgery. Clinicians felt the discussion of the option of cardiac surgery is appropriate, however are hesitant due to ethical concerns and insufficient outcome data. Results from this study aim to promote discussion and collaboration among clinicians to improve consistency in patient care.

Prenatal counseling and parental decision-making following a fetal diagnosis of trisomy 13 or 18

OBJECTIVES

To evaluate parental decisions following a prenatal diagnosis of trisomy 13 (T13) or trisomy 18 (T18), prenatal counseling received, and pregnancy outcomes.

STUDY DESIGN

Single-center, retrospective cohort study of families with a prenatal diagnosis of T13 or T18 from 2000 to 2016.

RESULTS

Out of 152 pregnancies, 55% were terminated. Twenty percent chose induction with palliative care, 20% chose expectant management, 2% chose full interventions, and 3% were lost to follow-up. Counseling was based on initial parental goals, but most women were given options besides termination. Women who chose expectant management had a live birth in 50% of the cases. Women who chose neonatal interventions had a live birth in 100% of the cases, but there were no long-term survivors.

CONCLUSIONS

The majority of women who continue their pregnancy after a fetal diagnosis of T13 or T18 desire expectant management with palliative care. A live birth can be expected at least half of the time.

Moving toward a shared process: The impact of parent experiences on perinatal palliative care

Perinatal palliative care programs seek to support parents expecting a baby diagnosed with a serious medical condition. Clinicians have increasingly recognized the importance of parental perspectives on the medical care mothers and their fetuses and live-born children receive, especially regarding factors influencing individual choices and knowledge of the medical community. We describe, using literature on trisomy 13 and trisomy 18, how information shared between parents and providers can improve perinatal counseling and family support.

Trisomy 13 and 18: Selecting the road previously not taken

The care of patients with trisomy 13 and 18 is a source of significant controversy. While these conditions are life limiting, indisputable data refutes the notion that these conditions are lethal or incompatible with life. Despite such evidence, arguments of beneficence, quality of life and limited resources are invoked to make the case to limit care to trisomy children. Lessons learned in our ignominious history with Down syndrome should guide us as we explore care for patients with trisomy 13 and 18. As clinicians we should strive with equipoise to carefully examine available data, the current status of practices related to care from palliation to intensive interventions, rise above our personal prejudices and listen to the voices of families imploring us to consider their opinions regarding the value of the life of a child with trisomy 13 or 18. We should recall and learn from our Down syndrome odyssey and select the road previously not taken as we chart a course to the best possible care for our trisomy 13 and 18 sisters and brothers. © 2016 Wiley Periodicals, Inc.

Publicly-funded home birth in Victoria, Australia: Exploring the views and experiences of midwives and doctors

OBJECTIVE

to explore midwives' and doctors' views and experiences of publicly-funded homebirthing models.

DESIGN

cross-sectional survey implemented two years after the introduction of publicly-funded homebirthing models.

SETTING

two public hospitals in Victoria, Australia.

PARTICIPANTS

midwives and doctors (obstetric medical staff).

MAIN OUTCOME MEASURES

midwives' and doctors' views regarding reasons women choose home birth; and views and experiences of a publicly-funded home birth program, including intrapartum transfers.

FINDINGS

of the 44% (74/167) of midwives who responded to the survey, the majority (86%) supported the introduction of a publicly-funded home birth model, and most considered that there was consumer demand for the model (83%). Most thought the model was safe for women (77%) and infants (78%). These views were stronger amongst midwives who had experience working in the program (compared with those who had not). Of the 25% (12/48) of doctors who responded, views were mixed; just under half-supported the introduction of a publicly-funded home birth model, and one was unsure. Doctors also had mixed views about the safety of the model. One third agreed it was safe for women, one third were neutral and one third disagreed. Half did not believe the home birth model was safe for infants. The majority of midwives (93%) and doctors (75%) believed that intrapartum transfers from home to hospital were easier when the homebirthing midwife was a member of the hospital staff (as is the case with these models).

KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE

responding midwives were supportive of the introduction of publicly-funded home birth, whereas doctors had divergent views and some were concerned about safety. To ensure the success of such programs it is critical that all key stakeholders are engaged at the development and implementation stages as well as in the ongoing governance.

Disability, discrimination and death: is it justified to ration life saving treatment for disabled newborn infants?

Disability might be relevant to decisions about life support in intensive care in several ways. It might affect the chance of treatment being successful, or a patient’s life expectancy with treatment. It may affect whether treatment is in a patient’s best interests. However, even if treatment would be of overall benefit it may be unaffordable and consequently unable to be provided. In this paper we will draw on the example of neonatal intensive care, and ask whether or when it is justified to ration life-saving treatment on the basis of disability. We argue that predicted disability is relevant both indirectly and directly to rationing decisions.

Ethical language and decision-making for prenatally diagnosed lethal malformations

In clinical practice, and in the medical literature, severe congenital malformations such as trisomy 18, anencephaly, and renal agenesis are frequently referred to as 'lethal' or as 'incompatible with life'. However, there is no agreement about a definition of lethal malformations, nor which conditions should be included in this category. Review of outcomes for malformations commonly designated 'lethal' reveals that prolonged survival is possible, even if rare. This article analyses the concept of lethal malformations and compares it to the problematic concept of 'futility'. We recommend avoiding the term 'lethal' and suggest that counseling should focus on salient prognostic features instead. For conditions with a high chance of early death or profound impairment in survivors despite treatment, perinatal and neonatal palliative care would be ethical. However, active obstetric and neonatal management, if desired, may also sometimes be appropriate.
