1 · What the graph read from it

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.

2 · The registry

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

backgroundDigital coordination tools have been proposed to improve management during mass casualty incidents (MCIs). In 2021, the IVENA-MANV system was introduced in the Hannover region as an extension of the established IVENA eHealth platform to enable digital patient tracking and hospital capacity management. However, no real-world evaluations have yet quantified their operational impact.

objectivesThis study aimed to provide the first real-world evaluation of the IVENA-MANV digital coordination system and to determine how its implementation affected prehospital distribution processes and time intervals during mass casualty incidents.

methodsA retrospective observational study to assess the impact of the IVENA-MANV digital coordination platform on prehospital times during MCIs in Germany was conducted using dispatch records and IVENA-MANV logs from all MCIs between January 2018 and July 2025 in the Hanover-Region in Germany. Primary outcomes were the triage-to-evacuation (TtE) and total prehospital time (TPHT) per patient. Mann-Whitney U tests compared pre- and post-implementation groups, and multiple linear regression models examined associations between IVENA-MANV use, MCI-level, and time intervals.

resultsSeventy-three MCIs met inclusion criteria, including 188 documented individual casualty characteristics. 41.1% of incidents used IVENA-MANV. Most MCIs were trauma-related (65.8%) and traffic-associated (64.4%). Mean TtE was 40.2 ± 19.3 min, and mean TPHT 83.9 ± 29.5 min. No statistically significant differences were found between pre- and post-implementation cohorts (p > 0.05). Regression analysis confirmed MCI-level as the only significant predictor of prolonged intervals (p < 0.001). IVENA-MANV enabled structured hospital allocation and real-time capacity confirmation (mean 1.8 min to first confirmation) without extending on-scene times.

conclusionsImplementation of IVENA-MANV did not significantly affect prehospital time intervals but demonstrated qualitative benefits for coordination, documentation, and hospital communication. The value of digital systems in disaster medicine may therefore lie in strengthening coordination and information resilience rather than accelerating evacuation. Prospective multicentre and mixed-methods studies are warranted to assess their broader system-level impact.
