30-Second Takeaway
- Prehospital AI mortality prediction markedly outperforms simple indices and could reshape destination and resource decisions.
- Severe TBI exhibits a distinct coagulopathy pattern, altering transfusion risk relative to isolated torso trauma.
- Field trauma triage updates transiently reduce undertriage, underscoring the need for continuous system monitoring.
- Recombinant thrombomodulin use in pancreatitis-related DIC is associated with lower in-hospital mortality.
- Biomarker-guided antibiotic discontinuation and rigorous delirium and sepsis bundle practices can improve ICU outcomes and stewardship.

Trauma systems, resuscitation, and critical care: recalibrating triage, coagulopathy management, and ICU stewardship
Prehospital AI model substantially improves prediction of trauma mortality over simple indices
An ensemble Prehospital-AI model using 21 prehospital variables predicted emergency room mortality with AUROC 0.923, outperforming shock index (AUROC 0.712). External validation across four South Korean trauma centers showed AUROC 0.925–0.956, and 0.895 in an Australian Level 1 center. Sensitivity and specificity in the test cohort were 0.780 and 0.880, supporting clinically useful discrimination for real-time triage. These data suggest AI-based tools could refine destination decisions, activation levels, and resource mobilization, but broader multinational validation remains necessary.
Severe TBI shows a distinct coagulopathy pattern affecting transfusion risk
This pooled analysis of hemorrhagic shock trials identified 506 patients as isolated severe TBI, polytrauma with TBI, or isolated torso/extremity trauma. For isolated TBI and polytrauma, principal component 1 combining INR, alpha angle, K time, and MA was linked to higher early transfusion odds. Odds ratios for early transfusion were 3.57 in isolated TBI and 2.29 in polytrauma, indicating a bleeding phenotype requiring aggressive support. In isolated torso/extremity trauma, principal component 1 (INR, alpha angle, MA) was protective with reduced transfusion odds (OR 0.51). These findings support that severe TBI is linked to a unique coagulation profile, suggesting TBI-specific resuscitation and massive transfusion approaches.
2015 field triage update briefly reduces undertriage in a mature trauma system
This Ontario population-based cohort included 281,268 trauma patients over 11 years, with 19.2% initially presenting to a trauma center. Population-level undertriage and overtriage rates were 63.5% and 12.3%, respectively, reflecting substantial triage inefficiency. Implementation of updated 2015 field trauma triage guidelines produced an immediate 15.2% reduction in undertriage (rate ratio 0.85, 95% CI 0.77–0.94). There was no immediate change in overtriage (rate ratio 0.90, 95% CI 0.79–1.04), and undertriage drifted upward again over subsequent years. These results imply guideline revisions alone are insufficient; continuous monitoring, feedback, and system-level reinforcements are required to sustain triage gains.
