Is Your Child's Transport Team Prepared? How Early Warning Systems Can Help
"A new study reveals the importance of early warning systems in pediatric interfacility transport, ensuring the right interventions at the right time."
When a child needs to be transferred from one hospital to another, it's a race against time. These transports, known as interfacility transports, require specialized teams and equipment to ensure the child's safety and well-being. But how do these teams know what to expect before they even arrive?
A recent study published in Pediatric Critical Care Medicine sheds light on the potential of Bedside Pediatric Early Warning Systems (BedsidePEWS) as a remote assessment tool. This system, already validated for measuring illness severity in inpatient settings, could be the key to optimizing care during these critical transports.
The study hypothesized that BedsidePEWS scores are associated with the need for intervention during the peritransport period and patient disposition. By evaluating this connection, the researchers aimed to improve the efficiency and effectiveness of pediatric interfacility transport.
From Warning Scores to Transport Planning
Paediatric early warning systems and paediatric track and trigger tools are increasingly used in paediatric units across Europe, North America, Australia and elsewhere, although their validity and effectiveness remain the subject of review. A modified Pediatric Early Warning Score has been used during transport to assess illness severity, but it was not designed to guide transport decisions. The Pediatric Transport Triage Tool was developed to objectively guide transport mode and team composition, helping standardize transport planning.
Decoding BedsidePEWS: A Score That Could Save Lives
The BedsidePEWS score is a seven-component physiological assessment that helps predict clinical deterioration in children. It's designed to be used by healthcare professionals to identify potential problems early on, allowing for timely interventions. The score takes into account vital signs and other key indicators to provide a comprehensive picture of a child's condition.
- Higher scores, more intervention: Children who received interventions during transport had significantly higher BedsidePEWS scores compared to those who didn't (8 vs. 2).
- Destination matters: Children transferred to the PICU had the highest scores (6), followed by those admitted to the ward (3) and the emergency department (2).
- Early warning: The BedsidePEWS score at the time of the initial referral was a strong indicator of subsequent peritransport intervention and the ultimate transfer destination.
Recent Evidence on PEWS
Recent reports describe Pediatric Early Warning Scores as potentially useful for triage and decisions about ambulance crew composition. Higher scores have been associated with PICU admission and increased risks of medical interventions during transport. In a retrospective study of 564 pediatric transports, children transferred to the PICU had higher bedside PEWS scores, with a reported median of 6 and a range of 3–10.
Limits of Objectivity
Pediatric early warning scores are intended to help identify children at risk of clinical decompensation, cardiac or respiratory arrest, or transfer to a higher level of care. However, one study illustrates nurses' concerns that an objective tool may not fully reflect subjective clinical assessment. The sources also report little consistency between tools and limited research evaluating their effectiveness, despite widespread use.
Different Tools, Different Roles
The Brighton Pediatric Early Warning Score is used in all Norwegian paediatric departments for children aged 0–18 years and evaluates medical risk using measures such as respiratory rate, oxygen requirements, pulse and behaviour documented over time. Transport-specific tools serve a different purpose: Transport Pediatric Early Warning Scores and Transport Risk Assessment in Pediatrics scores are adjuncts for determining the disposition of transported patients. The Pediatric Transport Triage Tool was instead created to guide transport mode and team configuration, rather than simply measure illness severity.
The Future of Pediatric Transport: Proactive, Prepared, and Patient-Centered
This study provides compelling evidence that the BedsidePEWS score can be a valuable tool for assessing the severity of illness in children requiring interfacility transport. By using this score, transport teams can better anticipate the needs of their patients and ensure they have the right resources and expertise on board.
Scoring Is Not Yet Standardized
Transport Risk Assessment in Pediatrics and Transport Pediatric Early Warning Scores are described as transport-specific illness-severity scores that support disposition decisions for transported patients. Yet severity-of-illness scoring is not consistently performed by pediatric interfacility transport programs in North America. Among programs that use a scoring tool, the timing of scoring, personnel applying it and frequency of analysis vary.
From Scores to Systems
Early Warning Scores and rapid response algorithms can provide a common framework for communication and response between physicians and nurses. However, their impact on interprofessional collaboration has been minimally studied, particularly in resource-limited settings. A 2026 review also notes that challenges remain before emerging monitoring technologies can be seamlessly integrated into routine clinical decision-making and clinical decision support.
Supporting Clinical Judgment
Effective pediatric triage requires a balance between rapid visual assessment and objective physiological monitoring, and the comparative ability of the Pediatric Assessment Triangle and Pediatric Early Warning Score to predict critical outcomes in real-world emergency settings is not yet fully established. At one hospital, PEWS was used to monitor deterioration and acuity during transport, while an escalation algorithm aimed to achieve an 80% PEWS completion rate during transport within six months. These examples place the score within a broader process of assessment, communication and escalation rather than treating it as a replacement for clinical judgment.
While the study has some limitations, including its retrospective nature and single-center design, it opens the door for future research and implementation of BedsidePEWS in pediatric transport. Further multicenter studies are needed to prospectively validate the score and determine its impact on patient outcomes.
Ultimately, the goal is to create a more proactive and prepared transport system that puts the patient's needs first. By embracing early warning systems and other innovative tools, we can ensure that every child receives the best possible care during these critical moments.
