Pediatric Specialty Transport Teams Are Not Associated With Decreased 48-Hour Pediatric Intensive Care Unit Mortality: A Propensity Analysis of the VPS, LLC Database

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.

Pediatric Critical Care Transport: Survey of Current State in Latin America. Latin American Society of Pediatric Intensive Care Transport Committee

METHODS

An electronic, anonymous, multicenter survey housed by Monkey Survey was sent to physicians in LA and included questions about hospital and pediatric critical transport, resources available and level of car. Nineteen Latin-American countries were asked to complete the survey.

RESULTS

A total of 212 surveys were analyzed, achieving a representativity of 19 LA countries, being most participants (59.4%, n = 126) from South America (Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Paraguay, Peru, Uruguay and Venezuela). Most surveys were conducted by physicians of tertiary level centers (60.8%, n = 129), most of the institutions were classified by the participants as public health care centers (81.6%, n = 173). Most of the surveyed physicians (63.7%, n = 135) reported that there is a coordination center for critical care transport (CCT). In most cases, physicians report that a unified transport system for pediatric critical patients does not exist in their countries (67.45%, n = 143). Only 59 (30.7%) surveys reported the use of an exclusively pediatric critical care transport system. Most of these transport systems are described as a mixture of public and private efforts (51.56%, n = 99), but there is also a considerable involvement of government-funded critical transport systems (43.75%, n = 84). Specific training for personnel devoted to transportation of critically ill patients is reported in 55.6% (90), and the medical equipment necessary to carry out the transport is available in 67.7%. The majority (83.95%, n = 136) mentioned that access to advanced life support courses is possible. Training in triage and disaster is available in 44.1%. Physicians and registered nurse were identified as the transport providers in 41.5%, and only one third were made by pediatricians-pediatric nurse. The main reasons for transfers were respiratory illness, neonatal pathologies, trauma, infectious diseases, and neurological conditions. Overall, pediatric transport was reported as insufficient (70.19%, n = 148) by the surveyed physicians in LA and nonexisting by some of them (6.83%, n = 15). There were no regulations or laws in the majority of the surveyed countries (63.13%), and in the places where physicians reported regulatory laws, there were no dissemination (84.9%) by the local authorities.

CONCLUSIONS

In LA, there is a great variability in personnel training, equipment for pediatric-neonatal transport, transport team composition, and characterization of critical care transport systems. Continued efforts to improve conditions in our countries by generating documents that standardize practices and generating scientific information on the epidemiology of pediatric transfers, especially of critically ill patients, may help reduce patient morbidity and mortality.

Characteristics of Medically Transported Critically Ill Children with Respiratory Failure in Latin America: Implications for Outcomes

Several challenges exist for referral and transport of critically ill children in resource-limited regions such as Latin America; however, little is known about factors associated with clinical outcomes. Thus, we aimed to describe the characteristics of critically ill children in Latin America transferred to pediatric intensive care units for acute respiratory failure to identify risk factors for mortality. We analyzed data from 2,692 patients admitted to 28 centers in the Pediatric Collaborative Network of Latin America Acute Respiratory Failure Registry. Among patients referred from another facility (773, 28%), nonurban transports were independently associated with mortality (adjusted odds ratio = 9.4; 95% confidence interval: 2.4–36.3).

The Evaluation of Transported Children to Pediatric Intensive Care Unit: Indications, Problems, and Outcomes

OBJECTIVE

Critically ill children often require transport to tertiary centers where higher levels of care can be provided. In this study, we aimed to evaluate the reasons for transport, complications that occurred during transport, and the clinical outcomes of the patients transferred to our tertiary pediatric intensive care unit (PICU).

METHODS

This retrospective study was conducted in a tertiary pediatric hospital with 250 beds and 20 tertiary PICU beds.

RESULTS

During the study period, 108 patients were transferred to our PICU. The mean age was 75.0 ± 70.5 months (range, 1-211 months), and 59 were female. Most patients (82.4%) were transported by land; 17.6% were transported by air ambulance. Fourteen patients were referred for liver transplantation, and 7 patients were referred because of a need for extracorporeal membrane oxygenation support and heart transplantation or left ventricular assist device placement. Two patients were transported by air while on extracorporeal membrane oxygenation. Complications occurred in 25% of patients.

CONCLUSION

Vital signs were assesed, and certain critical interventions such as intravenous fluids and respiratory support were provided more frequently during air transport, possibly due to the fact that physicians were always present during air transport. Quality improvement of transport teams and multicenter and nationwide studies on PICU transport are needed.

The effect of care provided by paediatric critical care transport teams on mortality of children transported to paediatric intensive care units in England and Wales: a retrospective cohort study

Background

Centralisation of paediatric intensive care units (PICUs) has the increased the need for specialist paediatric critical care transport teams (PCCT) to transport critically ill children to PICU. We investigated the impact of care provided by PCCTs for children on mortality and other clinically important outcomes.

Methods

We analysed linked national data from the Paediatric Intensive Care Audit Network (PICANet) from children admitted to PICUs in England and Wales (2014–2016) to assess the impact of who led the child’s transport, whether prolonged stabilisation by the PCCT was detrimental and the impact of critical incidents during transport on patient outcome. We used logistic regression models to estimate the adjusted odds and probability of mortality within 30 days of admission to PICU (primary outcome) and negative binomial models to investigate length of stay (LOS) and length of invasive ventilation (LOV).

Results

The study included 9112 children transported to PICU. The most common diagnosis was respiratory problems; junior doctors led the PCCT in just over half of all transports; and the 30-day mortality was 7.1%. Transports led by Advanced Nurse Practitioners and Junior Doctors had similar outcomes (adjusted mortality ANP: 0.035 versus Junior Doctor: 0.038). Prolonged stabilisation by the PCCT was possibly associated with increased mortality (0.059, 95% CI: 0.040 to 0.079 versus short stabilisation 0.044, 95% CI: 0.039 to 0.048). Critical incidents involving the child increased the adjusted odds of mortality within 30 days (odds ratio: 3.07).

Conclusions

Variations in team composition between PCCTs appear to have little effect on patient outcomes. We believe differences in stabilisation approaches are due to residual confounding. Our finding that critical incidents were associated with worse outcomes indicates that safety during critical care transport is an important area for future quality improvement work.

Interhospital Transport of Critically Ill Children to PICUs in the United Kingdom and Republic of Ireland: Analysis of an International Dataset

OBJECTIVES

International data on characteristics and outcomes of children transported from general hospitals to PICUs are scarce. We aimed to 1) describe the development of a common transport dataset in the United Kingdom and Ireland and 2) analyze transport data from a recent 2-year period.

DESIGN

Retrospective analysis of prospectively collected data.

SETTING

Specialist pediatric critical care transport teams and PICUs in the United Kingdom and Ireland.

PATIENTS

Critically ill children less than 16 years old transported by pediatric critical care transport teams to PICUs in the United Kingdom and Ireland.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

A common transport dataset was developed as part of the Paediatric Intensive Care Audit Network, and standardized data were collected from all PICUs and pediatric critical care transport teams from 2012. Anonymized data on transports (and linked PICU admissions) from a 2-year period (2014-2015) were analyzed to describe patient and transport characteristics, and in uni- and multivariate analyses, to study the association between key transport factors and PICU mortality. A total of 8,167 records were analyzed. Transported children were severely ill (median predicted mortality risk 4.4%) with around half being infants (4,226/8,167; 51.7%) and nearly half presenting with respiratory illnesses (3,619/8,167; 44.3%). The majority of transports were led by physicians (78.4%; consultants: 3,059/8,167, fellows: 3,344/8,167). The median time for a pediatric critical care transport team to arrive at the patient's bedside from referral was 85 minutes (interquartile range, 58-135 min). Adverse events occurred in 369 transports (4.5%). There were considerable variations in how transports were organized and delivered across pediatric critical care transport teams. In multivariate analyses, consultant team leader and transport from an intensive care area were associated with PICU mortality (p = 0.006).

CONCLUSIONS

Variations exist in United Kingdom and Ireland services for critically ill children needing interhospital transport. Future studies should assess the impact of these variations on long-term patient outcomes taking into account treatment provided prior to transport.

The Effect of Team Configuration on the Incidence of Adverse Events in Pediatric Critical Care Transport

OBJECTIVE

Specialty pediatric transport teams are widely used for pediatric interfacility transport in the United States, with little industry consensus on optimal team configuration. The aim of this study is to assess the quality of the nurse/paramedic specialty team configuration as indirectly measured by the rate of adverse events in these transports.

METHODS

Retrospective analysis of pediatric transport data from a hospital-based dedicated pediatric/neonatal transport team was conducted for patients transported in 2016. Data were categorized by general characteristics of transport and analyzed for the occurrence of adverse events.

RESULTS

Five hundred sixty-four cases were analyzed. Cases were described by team configuration and then by transport mode, duration, time, patient age and acuity, and disposition. The overall rate of adverse event incidence was 8.3%, chiefly centered in device and process domains. There was no significant difference in the rate of adverse events between team configurations.

CONCLUSION

There was no significant difference in the rate of adverse event occurrence in nurse/paramedic team configurations versus nurse/nurse configuration. Using critical care paramedics on pediatric transport teams enables a larger volume of patients to be transported to definitive care without concerns for decrease in quality or safety.
