Retrospective cohort study of all deaths among infants born between 22 and 27 completed weeks of gestation in Switzerland over a 3-year period

End of life care in the setting of extreme prematurity - practical challenges and ethical controversies

While the underlying principles are the same, there are differences in practice in end of life decisions and care for extremely preterm infants compared with other newborns and older children. In this paper, we review end of life care for extremely preterm infants in the delivery room and in the neonatal intensive care unit. We identify potential justifications for differences in the end of life care in this population as well as practical and ethical challenges.

Specialized Pediatric Palliative Care in Neonates with Life-Limiting Illness: A Systematic Review

OBJECTIVE

The aim of this study is to assess the impact of specialized pediatric palliative care (PPC) on neonates with life-limiting conditions compared to standard care.

STUDY DESIGN

MEDLINE, PsycINFO, Cochrane Central Register of Controlled Trials, Web of Science, CINAHL, Scopus, and Embase databases were searched from January 2000 to September 2018. Randomized clinical trials, experimental or observational studies, and secondary administrative database analyses published in English, Spanish, French, and German were included. Two independent reviewers extracted data, and used the Newcastle-Ottawa Scale and the Cochrane Risk of Bias Tool for quality analysis. Discrepancies were resolved as a team.

RESULTS

From the 37,788 records obtained, only eight articles met the inclusion criteria. A meta-analysis was not possible due to the heterogeneity in how the outcomes were defined; however, a qualitative synthesis of the results was possible; organizing outcomes into eight different categories: psychological, social and spiritual support; communication; location of care; symptom management; bereavement care; predicted versus actual neonatal outcomes; and parental coping, stress, and satisfaction.

CONCLUSION

Specialized versus may have an impact on neonates with life-limiting conditions and their families. More studies that evaluate the impact of specialized versus in neonates with sound statistical analysis is warranted.

National Divergences in Perinatal Palliative Care Guidelines and Training in Tertiary NICUs

Objectives: Despite established principles of perinatal palliative care (PnPC), implementation into practice has shown inconsistencies. The aim of this study was to assess PnPC services, examine healthcare professionals (HCPs) awareness and availability of PnPC guidelines, and describe HCPs satisfaction with PC and guidelines. Material and Methods: A nationwide survey was conducted in Swiss tertiary NICUs between April-November 2019. Data were examined by descriptive statistics and linear regression models. Results: Overall response rate was 54% (65% physicians; 49% nurses; 72% psychosocial staff). Half of professionals (50%) received education in PC during their medical/nursing school, whereas 36% indicated they obtained further training in PnPC at their center. PnPC guidelines were available in 4/9 centers, with 68% HCPs being aware of the guideline. Professionals who had access to a PnPC team (P = 0.001) or were part of the nursing (P = 0.003) or psychosocial staff (P = 0.001) were more likely aware of having a guideline. Twenty-eight percent indicated being satisfied with PC in their center. Professionals with guideline awareness (P = 0.025), further training (P = 0.001), and access to a PnPC team (P < 0.001) were more likely to be satisfied, whereas HCPs with a nursing background (P < 0.001) were more likely to be dissatisfied. A majority expressed the need for a PnPC guideline (80%) and further PC training (94%). Conclusion: This study reveals lacking PnPC guidelines and divergences regarding onsite opportunities for continued training across Swiss level III NICUs. Extending PnPC guidelines and training services to all centers can help bridge the barriers created by fragmented practice.

Higher incidence of retinopathy of prematurity in extremely preterm infants associated with improved survival rates

AIM

This study assessed possible reasons for the increasing incidence of retinopathy of prematurity (ROP) since mid-2015 at our institution.

METHODS

Retrospective analysis of all preterm infants born July 2013 to June 2017 with a gestational age (GA) <29 completed weeks admitted to the neonatal intensive care unit at the University Hospital Zurich during the first 28 days of life. The primary outcome measures were severest ROP stage. Statistical analysis was performed using generalised additive models in R.

RESULTS

During the study period, survival increased in extremely preterm infants. Significant predictors for severest ROP stage were GA, days of mechanical ventilation and multiple gestation (P = .0322). A composite of severe comorbidities had no significant effect on severest ROP stage. GA was identified as the only significant risk factor the for severest ROP stage (P = .0045).

CONCLUSION

Increased survival rate of extremely preterm infants was associated with an increased incidence of ROP at our institution. Despite the increase, the incidence is still very low compared with other countries. No other additive factors were identified.

Association between perinatal interventional activity and 2-year outcome of Swiss extremely preterm born infants: a population-based cohort study

OBJECTIVES

To investigate if centre-specific levels of perinatal interventional activity were associated with neonatal and neurodevelopmental outcome at 2 years of age in two separately analysed cohorts of infants: cohort A born at 22-25 and cohort B born at 26-27 gestational weeks, respectively.

DESIGN

Geographically defined, retrospective cohort study.

SETTING

All nine level III perinatal centres (neonatal intensive care units and affiliated obstetrical services) in Switzerland.

PATIENTS

All live-born infants in Switzerland in 2006-2013 below 28 gestational weeks, excluding infants with major congenital malformation.

OUTCOME MEASURES

Outcomes at 2 years corrected for prematurity were mortality, survival with any major neonatal morbidity and with severe-to-moderate neurodevelopmental impairment (NDI).

RESULTS

Cohort A associated birth in a centre with high perinatal activity with low mortality adjusted OR (aOR 0.22; 95% CI 0.16 to 0.32), while no association was observed with survival with major morbidity (aOR 0.74; 95% CI 0.46 to 1.19) and with NDI (aOR 0.97; 95% CI 0.46 to 2.02). Median age at death (8 vs 4 days) and length of stay (100 vs 73 days) were higher in high than in low activity centres. The results for cohort B mirrored those for cohort A.

CONCLUSIONS

Centres with high perinatal activity in Switzerland have a significantly lower risk for mortality while having comparable outcomes among survivors. This confirms the results of other studies but in a geographically defined area applying a more restrictive approach to initiation of perinatal intensive care than previous studies. The study adds that infants up to 28 weeks benefited from a higher perinatal activity and why further research is required to better estimate the added burden on children who ultimately do not survive.

Extremely premature infants: How does death in the delivery room influence mortality rates in two level 3 centers in France?

OBJECTIVES

Mortality rates of very preterm infants may vary considerably between healthcare facilities depending on the neonates' place of inclusion in the cohort study. The objective of this study was to compare the mortality rates of live-born extremely preterm neonates observed in two French tertiary referral hospitals, taking into account the occurrence of neonatal death both in the delivery room and in the neonatal intensive care unit (NICU).

METHODS

Retrospective observational study including all pregnancy terminations, stillbirths and live-born infants within a 22- to 26-week ^0/6 gestational age range was registered by two French level 3 university centers between 2009 and 2013. The mortality rates were compared between the two centers according to two places of inclusion: either the delivery room or the NICU.

RESULTS

A total of 344 infants were born at center A and 160 infants were born at center B. Among the live-born neonates, the rates of neonatal death were similar in center A (54/125, 43.2%) and center B (33/69, 47.8%; P=0.54). However, neonatal death occurred significantly more often in the delivery room at center A (31/54, 57.4%) than at center B (6/33, 18.2%; P<0.001). Finally, the neonatal death rate of live-born very preterm neonates admitted to the NICU was significantly lower in center A (25/94, 26.6%) than in center B (27/63, 42.9%; P=0.03).

CONCLUSIONS

This study points out how the inclusion of deaths in the delivery room when comparing neonatal death rates can lead to a substantial bias in benchmarking studies. Center A and center B each endorsed one of the two models of preferential place of neonatal death (delivery room or NICU) detailed in European studies. The reasons behind the two different models and their impact on how parents perceive supporting their neonate need further investigation.

Decision-making at the limit of viability: differing perceptions and opinions between neonatal physicians and nurses

Background

In the last 20 years, the chances for intact survival for extremely preterm infants have increased in high income countries. Decisions about withholding or withdrawing intensive care remain a major challenge in infants born at the limits of viability. Shared decision-making regarding these fragile infants between health care professionals and parents has become the preferred model today. However, there is an ongoing ethical debate on how decisions regarding life-sustaining treatment should be reached and who should have the final word when health care professionals and parents do not agree. We designed a survey among neonatologists and neonatal nurses to analyze practices, difficulties and parental involvement in end-of-life decisions for extremely preterm infants.

Methods

All 552 physicians and nurses with at least 12 months work experience in level III neonatal intensive care units (NICU) in Switzerland were invited to participate in an online survey with 50 questions. Differences between neonatologists and NICU nurses and between language regions were explored.

Results

Ninety six of 121 (79%) physicians and 302 of 431(70%) nurses completed the online questionnaire. The following difficulties with end-of-life decision-making were reported more frequently by nurses than physicians: insufficient time for decision-making, legal constraints and lack of consistent unit policies. Nurses also mentioned a lack of solidarity in our society and shortage of services for disabled more often than physicians. In the context of limiting intensive care in selected circumstances, nurses considered withholding tube feedings and respiratory support less acceptable than physicians. Nurses were more reluctant to give parents full authority to decide on the course of action for their infant. In contrast to professional category (nurse or physician), language region, professional experience and religion had little influence if any on the answers given.

Conclusions

Physicians and nurses differ in many aspects of how and by whom end-of-life decisions should be made in extremely preterm infants. The divergencies between nurses and physicians may be due to differences in ethics education, varying focus in patient care and direct exposure to the patients. Acknowledging these differences is important to avoid potential conflicts within the neonatal team but also with parents in the process of end-of-life decision-making in preterm infants born at the limits of viability.

"You Can Only Give Warmth to Your Baby When It's Too Late": Parents' Bonding With Their Extremely Preterm and Dying Child

This study on end-of-life decisions in extremely preterm babies shows that the parents under study experience a multitude of stressors due to the immediate separation after birth, the alienating setting of the neonatal intensive care unit (NICU), the physical distance to the child, medical uncertainties, and upcoming decisions. Even though they are considered to be parents (assigned parenthood), they cannot act as primary caregivers. Instead, they depend on professional instructions for access and care. Embodied parenthood can be experienced only at the end-of-life, that is, during the dying trajectory and after the child's death. Professionally supporting parents during this compressed process (from assigned and distant to embodied parenthood) contributes fundamentally to their perception of being a family and supports their mourning. This calls for the further establishment of palliative and bereavement care concepts in neonatology.
