The Impact of Comprehensive Fetal Care on Mortality of Children With Congenital Diaphragmatic Hernia when Delivery is Co-located in a Pediatric Hospital

BACKGROUND

We evaluated the impact of delivery at a comprehensive fetal care center co-located in a pediatric hospital on extracorporeal membrane oxygenation (ECMO) exposure and survivorship of children with CDH.

METHODS

This retrospective study includes maternal-fetal dyads with a prenatal diagnosis of isolated CDH who received any prenatal care at a single fetal center between February 2006 and March 2021. The principal variables included: (1) delivery setting (children born in the pediatric hospital ["inborn"] vs. children who were delivered elsewhere ["outborn"]), (2) exposure to ECMO (yes vs. no), and (3) survival-at-discharge from birth hospitalization (yes vs. no). Multivariable logistic regression was used to evaluate the association between delivery setting and ECMO cannulation, and whether delivery setting moderates the association between exposure to ECMO and survival-at-discharge.

RESULTS

Among 418 maternal-fetal dyads, 77.0% of children were inborn and 32.0% of children were exposed to ECMO during their index hospitalization. Inborn children had more severe prenatal prognostic indicators but had a 57% lower odds of extracorporeal than outborn children. In multivariable logistic regression, delivery setting moderated the association between exposure to ECMO and survival-at-discharge. Although there was no statistically significant difference in mortality between inborn and outborn children who were not exposed to ECMO, inborn children exposed to ECMO had a 6.86 (1.98, 23.74) increased odds of death and outborn children exposed to ECMO had a 17.71 (4.69, 66.87) increased odds of death when both were compared to non-cannulated outborn children.

CONCLUSIONS

Comprehensive fetal care with delivery co-located in a pediatric hospital was associated with decreased exposure to ECMO and a survivorship advantage among children with CDH who required extracorporeal support.

Neonatal Transport Safety Metrics and Adverse Event Reporting: A Systematic Review

OBJECTIVE

Neonatal transports are an essential component of regionalized medical systems. Neonates who are unstable after birth require transport to a higher level of care by neonatal transport teams. Data on adverse events on neonatal transports are limited. The aim of this study was to identify, evaluate, and summarize the findings of all relevant studies on adverse events on neonatal transports.

METHODS

We identified 38 studies reporting adverse events on neonatal transports from January 1, 2000, to December 31, 2019. The adverse events were distributed into 5 categories: vital sign abnormalities, laboratory value abnormalities, equipment challenges, system challenges, cardiopulmonary resuscitation, and transport-related mortality.

RESULTS

Most of the evidence surrounds vital sign abnormalities during transport (n = 28 studies), with hypothermia as the most frequently reported abnormal vital sign. Fourteen studies addressed laboratory abnormalities, 12 reported on events related to equipment issues, and 4 reported on system issues that lead to adverse events on transport. Of the 38 included studies, 12 included mortality related to transport as an outcome, and 4 reported on cardiopulmonary resuscitation during transport. There were significant variations in samples, definitions of adverse events, and research quality.

CONCLUSION

Adverse events during neonatal transport have been illuminated in various ways, with vital sign abnormalities most commonly explored in the literature. However, considerable variation in studies limits a clear understanding of the relative frequencies of each type of adverse event. The transport safety field would benefit from more efforts to standardize adverse event definitions, collect safety data prospectively, and pool data across larger care systems.

Nationwide survey of neonatal transportation practices in Japan

Rapid resuscitation and appropriate transportation of sick infants can greatly improve infant survival and neurological prognosis. To gain an understanding of the status of neonatal transport in Japan, we conducted a survey of neonatal transportation capabilities at perinatal medical centers across the country. Survey content included the number of neonatal transportation cases and the method of transportation. Twenty percent of infants admitted to neonatal intensive care units were transported to the medical centers from other institutions. Half of the level III perinatal medical centers owned an ambulance specialized for neonatal transport. A total of 36% of sick newborns, however, were transported by fire department ambulances that are ill-equipped to care for infants. Thirteen percent of centers reported problems with the emergency transportation of newborns in fire department ambulances. Centers lacked specialized ambulances primarily because of financial constraints. Adequate medical insurance coverage is needed to increase the number of specialized ambulances at perinatal medical centers.
