A thorough secondary survey not only builds on a strong primary survey but also systematically identifies injuries that may be subtle, hidden, or not volunteered by the patient, improving diagnostic accuracy and patient safety in trauma care.

The primary survey uses the DRCABCDE framework to rapidly identify and manage life-threatening conditions through structured triage and prioritisation. Used by first responders, EMTs, and pre-hospital clinicians, DRCABCDE provides a systematic approach to scene safety, early intervention, and effective emergency patient assessment.
