Paediatric sepsis remains a leading cause of preventable morbidity and mortality, contributing to 11 million deaths annually, including 1.2 million children [1, 2]. Early recognition is critical, yet prehospital identification is hindered by subtle presentations, age-related physiological variability, and limited diagnostic capability [1, 3]. Currently, no validated prehospital paediatric sepsis screening tool exists. The aim of this project was to develop and implement an evidence-based prehospital paediatric sepsis screening tool for paramedics.
The development process included a targeted literature review and formal stakeholder engagement with Hamad Medical Corporation Ambulance Service (HMCAS) and Sidra Medicine. The iterative tool refinement was informed by international guidelines, aligned with Sidra Medicine pathways, and adapted to support HMCAS clinical practice guidelines. Age-specific physiological thresholds were calibrated using Advanced Paediatrc Life Support vital-sign parameters within the sepsis context. Implementation was supported by a blended educational model comprising 4 hours of online preparatory modules, 7 hours of face-to-face workshops, and simulation-enhanced active learning sessions.
The final screening tool integrated infection-risk assessment, high-risk clinical criteria, age-specific vital-sign thresholds, and key physiological indicators, supported by an algorithm (Figure 1). A corresponding prehospital sepsis care bundle (Figure 2) was incorporated to standardise timely recognition, intervention, and escalation, aligned with the “Sepsis Golden Hour” and “Sepsis 6” principles [1, 3]. Clinical validation and alignment were provided through expert review by paediatric sepsis specialists from Sidra Medicine. Case-based learning, deliberate practice, and simulations supported the application of the tool for operational practice.
The Prehospital Paediatric Sepsis Screening Tool was successfully developed and implemented, supported by structured educational preparation to strengthen early recognition and clinical decision-making. By the end of Quarter 1, 2025, 1,513 HMCAS staff (89%) had completed the training. Future study with ongoing evaluation should examine the tool’s impact on recognition accuracy, timeliness of intervention, and patient outcomes across the prehospital paediatric sepsis pathway.
