Validation of the 2022 German trauma team activation criteria: a national registry study with focus on geriatric-specific modifiers.
Article in Scandinavian journal of trauma, resuscitation and emergency medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe 2022 revision of the German Trauma Society's (DGU) trauma team activation (TTA) criteria introduces geriatric-specific modifiers to enhance the sensitivity of risk stratification in older (elderly) trauma patients. This study evaluates the validity of these updated criteria using national registry data, with particular focus on mortality gradients across activation levels and the prognostic value of newly incorporated modifiers.
methodsWe conducted a retrospective cohort analysis of patients aged ≥ 60 years, defined as elderly trauma patients, from the TraumaRegister DGU
resultsAmong 66,273 elderly trauma patients, mortality according to the 2022 criteria showed a consistent risk gradient: 20.2% (high risk of severe injury, HRSI), 9.0% (moderate risk of severe injury, MRSI), and 4.2% (None). In contrast, the 2016 criteria yielded inconsistent patterns, including higher mortality in the "None" category. New modifiers were strongly predictive of mortality: multiple serious injuries in ≥ 2 regions (16.7% vs. 6.7%), SBP 91-100 mmHg (13.1% vs. 7.3%), and GCS 13-14 (12.5% vs. 5.6%). Pre-injury anticoagulation was associated with increased mortality across all subgroups (29.3% vs. 20.3%).
conclusionThe 2022 TTA criteria improve the alignment between triage criteria and observed mortality risk, particularly among elderly patients. The addition of geriatric-specific modifiers enhances predictive accuracy and clinical applicability. Future work should quantify implications for overtriage and resource allocation to support evidence-based trauma system optimization.
