Accuracy and Disparities in Pediatric Emergency Triage: A Multicenter Retrospective Cohort Study.
Article in Hospital pediatrics, 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
objectivesTo assess the accuracy of the Emergency Severity Index (ESI) in correctly stratifying high-risk pediatric patients and predicting resource use across multiple pediatric emergency departments (EDs), and to identify patient and environmental factors associated with triage accuracy.
backgroundThe ESI is widely used for ED triage in the United States, yet its performance in pediatric populations remains suboptimal. Limited multicenter data exist on factors contributing to inaccurate triage in children's hospitals.
methodsWe performed a cross-sectional cohort study using the Pediatric Emergency Care Applied Research Network (PECARN) Registry database from 2012 to 2023. The database includes 17 pediatric EDs across the United States. Undertriage was defined as greater than expected resource usage or acuity compared to the ESI level assigned at triage, and overtriage as being assigned an ESI level exceeding actual care provided. We used multivariable analysis to assess associations between triage accuracy and patient demographics and ED visit characteristics.
resultsWe evaluated 7.3 million visits. Accuracy was 33% overall, with 35% overtriaged and 32% undertriaged. Undertriage was more common among adolescents, non-English speakers, and minoritized populations. Overtriage was associated with newborn age and ED crowding. Patients who presented for complaints associated with standardized treatment protocols had higher accuracy rates.
conclusionsESI performance in PECARN Registry pediatric EDs was low, with accuracy varying by age, language, race, and ethnicity. Evidence-based guidelines and decision support tools may improve triage accuracy and reduce inequities.
