Survey shows marked variations in approaches to redirection of care for critically ill very preterm infants in 11 countries

Variations in neonatal mortality of preterm infants with intraparenchymal haemorrhage in Europe: the EPICE cohort

OBJECTIVE

The aim of this study was to investigate variations in mortality before neonatal intensive care unit (NICU) discharge of infants born preterm with intraparenchymal haemorrhage (IPH) in Europe with a special interest for withdrawing life-sustaining therapy (WLST).

DESIGN

Secondary analysis of the Effective Perinatal Intensive Care in Europe (EPICE) cohort, 2011-2012.

SETTING

Nineteen regions in 11 European countries.

PATIENTS

All infants born between 24+0 and 31+6 weeks' gestational age (GA) with a diagnosis of IPH.

MAIN OUTCOME MEASURES

Mortality rate with multivariable analysis after adjustment for GA, antenatal steroids and gender. WLST policies were described among NICUs and within countries.

RESULTS

Among 6828 infants born alive between 24+0 and 31+6 weeks' GA and without congenital anomalies admitted to NICUs, IPH was diagnosed in 234 infants (3.4%, 95% CI 3.3% to 3.9%) and 138 of them (59%) died. The median age at death was 6 days (3-13). Mortality rates varied significantly between countries (extremes: 30%-81%; p<0.004) and most infants (69%) died after WLST. After adjustment and with reference to the UK, mortality rates were significantly higher for France, Denmark and the Netherlands, with ORs of 8.8 (95% CI 3.3 to 23.6), 5.9 (95% CI 1.6 to 21.4) and 4.8 (95% CI 1.1 to 8.9). There were variations in WLST between European regions and countries.

CONCLUSION

In infants with IPH, rates of death before discharge and death after WLST varied between European countries. These variations in mortality impede studying reliable outcomes in infants with IPH across European countries and encourage reflection of clinical practices of WLST across European units.

Survival and unique clinical practices of extremely preterm infants born at 22-23 weeks' gestation in Japan: a national survey

OBJECTIVES

To investigate prognosis and clinical practices of infants born at 22-23 weeks' gestational age (wkGA) in Japan.

DESIGN

A national institutional-level electronic questionnaire surveys performed in September 2021.

SETTING

All perinatal centres across Japan.

PATIENTS

Infants born at 22-23 wkGA in 2018-2020.

MAIN OUTCOME MEASURES

Proportion of active resuscitation and survival at neonatal intensive care unit (NICU) discharge, and various clinical practices.

RESULTS

In total, 255 of 295 NICUs (86%) responded. Among them, 145 took care of infants born at 22-23 wkGA and answered the questions regarding their outcomes and care. In most NICUs (129 of 145 (89%)), infants born at 22+0 wkGA can be actively resuscitated. In almost half of the NICUs (79 of 145 (54%)), infants born at ≥22+0 wkGA were always actively resuscitated. Among 341 and 757 infants born alive at 22 and 23 wkGA, respectively, 85% (291 of 341) and 98% (745 of 757) received active resuscitation after birth. Among infants actively resuscitated at birth, 63% (183 of 291) and 80% (594 of 745) of infants born at 22 and 23 wkGA survived, respectively. The survey revealed unique clinical management for these infants in Japan, including delivery with caul in caesarean section, cut-cord milking after clamping cord, immediate intubation at birth, hydrocortisone use for chronic lung disease, analgesia/sedation use for infants on mechanical ventilation, routine echocardiography and brain ultrasound, probiotics administration, routine glycerin enema and skin dressing to prevent pressure ulcers.

CONCLUSIONS

Many 22-23 wkGA infants were actively resuscitated in Japan and had a high survival rate. Various unique clinical practices were highlighted.

Temporal Trends in Severe Brain Injury and Associated Outcomes in Very Preterm Infants

INTRODUCTION

Severe brain injury (SBI), including severe intraventricular haemorrhage (sIVH) and cystic periventricular leukomalacia, poses significant challenges for preterm infants, yet recent data and trends are limited.

METHODS

Analyses were conducted using the Australian and New Zealand Neonatal Network data on preterm infants born <32 weeks' gestation admitted at Monash Children's Hospital, Australia, from January 2014 to April 2021. The occurrence and trends of SBI and sIVH among preterm infants, along with the rates and trends of death and neurodevelopmental impairment (NDI) in SBI infants were assessed.

RESULTS

Of 1,609 preterm infants, 6.7% had SBI, and 5.6% exhibited sIVH. A total of 37.6% of infants with SBI did not survive to discharge, with 92% of these deaths occurring following redirection of clinical care. Cerebral palsy was diagnosed in 65.2% of SBI survivors, while 86.4% of SBI survivors experienced NDI. No statistically significant differences were observed in the temporal trends of SBI (adjusted OR [95% CI] 1.08 [0.97-1.20]; p = 0.13) or sIVH (adjusted OR [95% CI] 1.09 [0.97-1.21]; p = 0.11). Similarly, there was no statistically significant difference noted in the temporal trend of the composite outcome, which included death or NDI among infants with SBI (adjusted OR [95% CI] 0.90 [0.53-1.53]; p = 0.71).

CONCLUSION

Neither the rates of SBI nor its associated composite outcome of death or NDI improved over time. A notable proportion of preterm infants with SBI faced redirection of care and subsequent mortality, while most survivors exhibited adverse neurodevelopmental challenges. The development of better therapeutic interventions is imperative to improve outcomes for these vulnerable infants.

Circumstances, causes and timing of death in extremely preterm infants admitted to NICU: The EPIPAGE-2 study

AIM

To describe the circumstances, causes and timing of death in extremely preterm infants.

METHODS

We included from the EPIPAGE-2 study infants born at 24-26 weeks in 2011 admitted to neonatal intensive care units (NICU). Vital status and circumstances of death were used to define three groups of infants: alive at discharge, death with or without withholding or withdrawing life-sustaining treatment (WWLST). The main cause of death was classified as respiratory disease, necrotizing enterocolitis, infection, central nervous system (CNS) injury, other or unknown.

RESULTS

Among 768 infants admitted to NICU, 224 died among which 89 died without WWLST and 135 with WWLST. The main causes of death were respiratory disease (38%), CNS injury (30%) and infection (12%). Among the infants who died with WWLST, CNS injury was the main cause of death (47%), whereas respiratory disease (56%) and infection (20%) were the main causes in case of death without WWLST. Half (51%) of all deaths occurred within the first 7 days of life, and 35% occurred within 8 and 28 days.

CONCLUSION

The death of extremely preterm infants in NICU is a complex phenomenon in which the circumstances and causes of death are intertwined.

Decision-making for extremely preterm infants with severe hemorrhages on head ultrasound: Science, values, and communication skills

Severe intracranial hemorrhages are not rare in extremely preterm infants. They occur early, generally when babies require life-sustaining interventions. This may lead to ethical discussions and decision-making about levels of care. Prognosis is variable and depends on the extent, location, and laterality of the lesions, and, importantly also on the subsequent occurrence of other clinical complications or progressive ventricular dilatation. Decision-making should depend on prognosis and parental values. This article will review prognosis and the uncertainty of outcomes for different lesions and provide an outline of ways to conduct an ethically appropriate discussion on the decision of whether to continue life sustaining therapy. It is possible to communicate in a compassionate and honest way with parents and engage in decision-making, focussing on personalized information and decisions, and on function, as opposed to diagnosis.

International Variation in the Management of Patent Ductus Arteriosus and Its Association with Infant Outcomes: A Survey and Linked Cohort Study

OBJECTIVE

To assess whether treating patients with a presymptomatic patent ductus arteriosus (PDA), based on early routine echocardiography, performed regardless of clinical signs, improved outcomes.

STUDY DESIGN

This multicenter, survey-linked retrospective cohort study used an institutional-level questionnaire and individual patient-level data and included infants of <29 weeks of gestation born in 2014-2016 and admitted to tertiary neonatal intensive care units (NICUs) of 9 population-based national or regional neonatal networks. Infants in NICUs receiving treatment of presymptomatic PDA identified by routine echocardiography and those not were compared for the primary composite outcome (early death [≤7 days after birth] or severe intraventricular hemorrhage) and secondary outcomes (any in-hospital mortality and major morbidities).

RESULTS

The unit survey (response rates of 86%) revealed a wide variation among networks in the treatment of presymptomatic PDA (7%-86%). Among 246 NICUs with 17 936 infants (mean gestational age of 26 weeks), 126 NICUs (51%) with 7785 infants treated presymptomatic PDA. The primary outcome of early death or severe intraventricular hemorrhage was not significantly different between the NICUs treating presymptomatic PDA and those who did not (17% vs 21%; aOR 1.00, 95% CI 0.85-1.18). The NICUs treating presymptomatic PDA had greater odds of retinopathy of prematurity treatment (13% vs 7%; aOR 1.47, 95% CI 1.01-2.12); however, it was not significant in a sensitivity analysis excluding Japanese data.

CONCLUSIONS

Treating presymptomatic PDA detected by routine echocardiography was commonplace but associated with no significant benefits. Well-designed trials are needed to assess the efficacy and safety of early targeted PDA treatment.

Variations in Neonatal Length of Stay of Babies Born Extremely Preterm: An International Comparison Between iNeo Networks

OBJECTIVE

To compare length of stay (LOS) in neonatal care for babies born extremely preterm admitted to networks participating in the International Network for Evaluating Outcomes of Neonates (iNeo).

STUDY DESIGN

Data were extracted for babies admitted from 2014 to 2016 and born at 24 to 28 weeks of gestational age (n = 28 204). Median LOS was calculated for each network for babies who survived and those who died while in neonatal care. A linear regression model was used to investigate differences in LOS between networks after adjusting for gestational age, birth weight z score, sex, and multiplicity. A sensitivity analysis was conducted for babies who were discharged home directly.

RESULTS

Observed median LOS for babies who survived was longest in Japan (107 days); this result persisted after adjustment (20.7 days more than reference, 95% CI 19.3-22.1). Finland had the shortest adjusted LOS (-4.8 days less than reference, 95% CI -7.3 to -2.3). For each week's increase in gestational age at birth, LOS decreased by 12.1 days (95% CI -12.3 to -11.9). Multiplicity and male sex predicted mean increases in LOS of 2.6 (95% CI 2.0-3.2) and 2.1 (95% CI 1.6-2.6) days, respectively.

CONCLUSIONS

We identified between-network differences in LOS of up to 3 weeks for babies born extremely preterm. Some of these may be partly explained by differences in mortality, but unexplained variations also may be related to differences in clinical care practices and healthcare systems between countries.
