The influence of socioeconomic status on pre-hospital triage in the Netherlands; a multi-center cohort study.
Article in European journal of trauma and emergency surgery : official publication of the European Trauma Society, 2025. 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
purposeOptimizing pre-hospital triage is essential to improve outcomes after severe injury. Sociodemographic factors may influence triage decision, but the role of neighborhood socioeconomic status (SES) at the scene of injury remains unclear. This study evaluated the association between neighborhood SES and the accuracy of pre-hospital trauma triage.
methodsThis multicenter cohort study included all trauma patients transported by eight ambulance regions in the Netherlands between January 2015 and December 2017. Neighborhood SES was defined using income, education, and employment indicators. Outcomes were undertriage and overtriage, based on Injury Severity Score (ISS) ≥ 16. Associations between SES and triage accuracy were analyzed with generalized linear models using inverse probability weighting, adjusted for age, trauma mechanism, injury severity, and trauma center proximity.
resultsA total of 160,109 patients were included, of whom 32,466 (20.2%) were injured in low-SES neighborhoods. Compared with higher-SES areas, these patients were younger (median 55.7 vs. 58.3 years), more often sustained penetrating injuries (1.3% vs. 0.7%), and were injured closer to higher-level centers (median 7.5 vs. 20.3 km). Unadjusted undertriage was lower (14.9% vs. 25.9%) and overtriage higher (27.8% vs. 19.4%). After adjustment, low-SES neighborhoods were associated with increased undertriage risk (aOR 1.30; 95% CI 1.03–1.63) and decreased overtriage risk (aOR 0.65; 95% CI 0.62–0.67).
conclusionNeighborhood SES is significantly associated with pre-hospital trauma triage. Severely injured patients in low-SES neighborhoods are at increased risk of undertriage, underscoring the need for targeted strategies to ensure equitable access to specialized trauma care.
