Introduction
Prolonged on-scene times in trauma are associated with delayed access to definitive care and poorer outcomes, particularly for physiologically critical but logistically uncomplicated patients. In volatile, uncertain, complex and ambiguous (VUCA) environments, cognitive overload, workflow drift and competing priorities commonly disrupt timely decision-making and transport progression.
Aims
To describe the momentum mindset as an operational approach to trauma care, using the OSCAR cognitive framework to optimise scene time, improve decision-making reliability, and support early transition to definitive care.
Methods
This work presents a practice-informed framework derived from reflective case analysis, pre-hospital literature and human factors theory. OSCAR (Oxygenation, Stretcher, Critical interventions, Anticipated problems, Rotate) is examined as a structured cognitive scaffold applied to trauma scenarios. The framework is interpreted through a VUCA mitigation lens (Vision, Understanding, Clarity, Agility) to support team cognition under stress.
Results
OSCAR reframes the traditional “stay and play” versus “load and go” dichotomy into a time-focused, sequence-driven approach. It prioritises immediate life-saving interventions, rapid transfer to a transport platform, selective delivery of only outcome-critical procedures, anticipatory preparation for deterioration, and early initiation of transport. As a cognitive aid, OSCAR reduces working memory burden, promotes shared mental models, and limits non-value-adding tasks that contribute to avoidable scene delay.
Conclusions
The momentum mindset, operationalised through OSCAR, offers a pragmatic strategy to improve scene efficiency and decision-making in trauma care. By stabilising cognition and maintaining forward progression in VUCA environments, it supports earlier access to definitive care. Embedding this approach within training and clinical governance may enhance performance, consistency and patient flow across pre-hospital trauma systems.
