• Injury severity measurement and triage tool development became a central research pattern, guiding resource allocation, outcome prediction, and cross-facility comparisons through field indices, reliability studies, and pediatric triage algorithms [2], [1], [8], [20].

• Diagnostic imaging usage and accuracy emerged as a key driver of triage decisions, with evidence from CT detection of splenic injury, radiograph justification for ankle trauma, and lavage-based assessments shaping management thresholds [5], [4], [6], [17].

• Trauma systems organization and disaster readiness became a dominant paradigm, foregrounding structured units, on-site medical coordination, and registry-based data to optimize care networks [10], [9], [7], [13].

• Injury patterns and mortality determinants were central to care prioritization, with analyses of pelvic fractures, long-bone injuries, fall-related lesions, and exsanguination highlighting key risk factors for death and resource needs [15], [11], [19], [12].

• Classification, coding, and epidemiology were advanced to enable surveillance, safety auditing, and policy guidance, linking ICD schemes, severity indexes, and epidemiologic reports to practice improvement [16], [3], [13], [10].
