Time-Critical Mechanism Flags
NoteFull time-critical physiological/anatomical criteria and thresholds are covered in the Major Trauma Assessment tool (JRCALC G0540/G0590/G0600). This screen flags RTC-specific mechanism indicators only โ tap any that apply.

Other Scene Considerations
Interior Causation โ Negated / Considered
Interior structures as a source of injury. Tap to cycle: not assessed โ negative โ positive. Positive reveals a findings field.
Injury Pattern Reference
Mechanism-based reference only โ not stateful. Cards tagged RELEVANT match the incident details entered. Source: published trauma biomechanics literature (RadioGraphics 2019;39:857โ876; other cited studies) โ distinct from JRCALC/NWAS guidance.
Canadian C-Spine Rule
Stiell et al. JAMA 2001;286:1841โ8Sensitivity 99.4โ100%
ScopeValidated for alert (GCS 15), haemodynamically stable trauma patients โฅ16 years, no distracting injury, no known vertebral disease or prior C-spine surgery. Not a JRCALC/NWAS document โ apply alongside local spinal motion restriction policy, which takes precedence where it differs.
Step 1 โ Any High-Risk Factor?
Step 2 โ Any Low-Risk Factor Present? (allows safe ROM testing)
Step 3 โ Active Range of Motion
Patient voluntarily rotates neck 45ยฐ left AND right, regardless of pain/discomfort.
Region & Limb Assessment
Tap to cycle: not assessed โ negative โ positive. Positive reveals findings chips + free text. Applies to occupants and pedestrians/cyclists.
Life-Threat Negation Checklist
Conditions that should be actively excluded given RTC mechanism, beyond the region survey above.
