AI powered patient records analysis for injury surveillance in children and adolescents - a feasibility study from Switzerland.
Article in International journal of public health, 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
Objective: This study investigates the feasibility of using an automated approach to extract injury-related information from narrative text in a paediatric emergency department to improve data basis on injuries among children and adolescents in Switzerland. Methods: The dataset comprises paediatric injury cases treated between 2018 and 2022 at the University Children's Hospital Zürich emergency department (N = 30,876). Model development involved (1) adapting EU-IDB, a domain-specific hierarchical Results: Interrater reliability improved from moderate (κ = 0.45) to substantial (κ = 0.73) following adaptation of the coding system. Variable level classification performance was encouraging across three training variants (macro F1: ALL = 0.57, IND = 0.64, VAR = 0.63). Performance declined at lower levels, particularly at level 3 (macro F1: ALL = 0.08, IND = 0.23). Automated prevalence estimates correlated strongly with manual annotations (ρ = 0.948). Conclusion: Automated text span classification of injury-relevant information from electronic patient records shows promising first results to provide valuable information for injury surveillance and prevention, missing in Switzerland. However, more annotated data and detailed validation are needed to draw robust conclusions.
