Do Pediatric Teams Affect Outcomes of Injured Children Requiring Inter-hospital Transport?

The Association Between Inter-Hospital Transfers and the Prognosis of Pediatric Injury in the Emergency Department

BACKGROUND

Inter-hospital transfers of severely injured patients are inevitable due to limited resources. We investigated the association between inter-hospital transfer and the prognosis of pediatric injury using the Korean multi-institutional injury registry.

METHODS

This retrospective observational study was conducted from January 2013 to December 2017; data for hospitalized subjects aged < 18 years were extracted from the Emergency Department-based Injury in Depth Surveillance database, in which 22 hospitals are participating as of 2022. The survival rates of the direct transfer group and the inter-hospital transfer group were compared, and risk factors affecting 30-day mortality and 72- hour mortality were analyzed.

RESULTS

The total number of study subjects was 18,518, and the transfer rate between hospitals was 14.5%. The overall mortality rate was 2.3% (n = 422), the 72-hour mortality was 1.7% (n = 315) and the 30-day mortality rate was 2.2% (n = 407). The Kaplan-Meier survival curve revealed a lower survival rate in the inter-hospital transfer group than in the direct visit group (log-rank, P < 0.001). Cox proportional hazards regression analysis showed that inter-hospital transfer group had a higher 30-day mortality rate and 72-hour mortality (hazard ratio [HR], 1.681; 95% confidence interval [CI], 1.232-2.294 and HR, 1.951; 95% CI, 1.299-2.930) than direct visit group when adjusting for age, sex, injury severity, and head injury.

CONCLUSION

Among the pediatric injured patients requiring hospitalization, inter-hospital transfer in the emergency department was associated with the 30-day mortality rate and 72-hour mortality rate in Korea.

Helicopter versus ground ambulance transport for interfacility transfer of critically ill children

BACKGROUND

Following initial stabilization, critically ill children often require transfer to a specialized pediatric hospital. While the use of specialized pediatric transport teams has been associated with improved outcomes for these patients, the additional influence of transfer mode (helicopter or ground ambulance) on clinical outcomes remains unknown.

METHODS

We investigated the association between transport mode and outcomes among critically ill children transferred to a single pediatric hospital via a specialized pediatric transport team. We designed a retrospective cohort study to reduce indication bias by limiting analysis to patients for whom a helicopter transport was initially requested. We compared outcomes for those who ultimately traveled via helicopter, and for those who ultimately traveled via ground ambulance due to non-clinical factors.

RESULTS

We compared transport times, in-hospital mortality, and hospital length of stay by transport mode. Transport time in minutes was shorter for helicopter transports (median = 143, interquartile range [IQR]: 118-184) compared to ground ambulance transports (median = 289, IQR: 213-258; difference in medians = 146, 95% CI: 12 to 168, p < 0.001). In unadjusted analysis, helicopter transport was not associated with a difference in in-hospital mortality (helicopter = 6.0%, ground ambulance = 7.0%; 95% CI for difference: -6.6% to 3.3%; p = 0.64) but was associated with a statistically significant reduction in median hospital days (helicopter = 4, ground ambulance = 5; 95% CI -3 to 0; p = 0.04). In adjusted analyses, there were no statistically significant associations. These results were consistent across sensitivity analyses.

CONCLUSIONS

Among critically ill pediatric patients without traumatic injuries transported by a specialty team, those patients who would have been transferred by helicopter if available but were instead transferred by ground ambulance reached their site of definitive care approximately 2.5 h later. Helicopter transport for these patients was not associated with in-hospital mortality, but was potentially associated with reduced hospital length of stay.

Importance of specialized paediatric and neonatal transport. Current situation in Spain: Towards a more equitable and universal future

Specialized paediatric and neonatal transport is a useful and essential resource in the interhospital transfer of these patients. It allows bringing the material and personal resources of an intensive care unit closer to the regional hospitals where the patient can be found. The benefits of these teams are very well demonstrated in the literature. These units should be part of the emergency systems, while it would be recommended that they be staff integrated in the tertiary hospitals, in order to maintain the necessary skills and competencies. The team, made up of physicians, nurses and emergency medical technicians, must master both the pathophysiology of transport and that of the critical patient in this age range. A high quality of both human and care is important, so continuous training and periodic recycling will be essential to be compliant with the quality indicators in transport. Likewise, it is essential to have specific vehicles adapted to this function, which allow carrying the wide variety of necessary material, as well as the electromedicine that is required. However, in Spain this paediatric and neonatal transport model is not standardized and therefore is not homogeneous: there are different models that do not always provide adequate quality, making it necessary to implement specialized units throughout the country to guarantee sanitary transport quality to any critical child or neonate.

Association Between Insurance and Transfer of Injured Children From Emergency Departments

OBJECTIVES

To determine if injured children presenting to nondesignated trauma centers are more or less likely to be transferred relative to being admitted based on insurance status.

METHODS

We conducted a cross-sectional study by using the Healthcare Cost and Utilization Project Nationwide Emergency Department Sample. Pediatric trauma patients receiving care in emergency departments (EDs) at nontrauma centers who were either admitted locally or transferred to another hospital were included. We performed logistic regression analysis adjusting for injury severity and other confounders and incorporated nationally representative weights to determine the association between insurance and transfer or admission.

RESULTS

Nine thousand four hundred and sixty-one ED pediatric trauma events at 386 nontrauma centers met inclusion criteria. EDs that treated a higher proportion of patients with Medicaid had higher odds of transfer relative to admission (odds ratio [OR]: 1.2 per 10% increase in Medicaid; 95% confidence interval [CI]: 1.1-1.4), resulting in overall higher odds of transfer among patients with Medicaid compared with patients with private insurance (OR: 1.3; 95% CI: 1.0-1.5). A patient's insurance status was not associated with different odds of transfer relative to admission within individual EDs after adjusting for the ED's proportion of patients with Medicaid (Medicaid OR: 1.0; 95% CI: 0.8-1.1).

CONCLUSIONS

Injured pediatric patients presenting to nondesignated trauma centers are slightly more likely to be transferred than admitted when the ED treats a higher proportion of Medicaid patients. In this study, ongoing concerns about inequities in the delivery of care among hospitals treating high proportions of children with Medicaid are reinforced.
