CT Utilisation in Emergency Department (ED) Assessment of Patients With Suspected Polytrauma: Impact of a Dedicated Trauma Surgical Team.
Article in Journal of medical imaging and radiation oncology, 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
introductionWe aimed to assess the impact of introduction of a dedicated trauma surgical unit (TSU) on CT utilisation for polytrauma in the Emergency Department (ED).
methodsSingle centre retrospective cohort study comparing adult patients undergoing CT for polytrauma following TSU introduction (Intervention group, n = 617) to a historical Baseline group (n = 257) over a matched time period. Patient impact, including initial clinical assessment, injuries, radiation exposure, incidental findings, ED disposition, and impact on radiology services were compared with Mann-Whitney and Fisher's exact tests.
resultsIntervention patients were more likely to be examined by ED physicians (96.7% vs. 91.1%, p = 0.001) prior to CT. There was greater documented clinical suspicion for chest and abdominal injuries, with increased WBCT utilisation for Intervention (Baseline 17.1% vs. 47.8%, p < 0.05), with no significant increase in positive scans by region. More CT chest (Intervention 38.4% vs. Baseline 14.8%, p < 0.05), CT abdomen (42.6% vs. 12.6%, p < 0.005) and CT pelvis (46.1% vs. 16%, p < 0.001) was performed even with low documented clinical suspicion, with no significant increase in positive findings. The intervention group returned for more additional scans (12.48% vs. Baseline 5.45%), had more incidental findings (23.66% vs. 15.18%), and were more likely to be admitted for observation (21.7% vs. 14%), all p < 0.05. Time to scan and total CT reporting time were significantly longer for Intervention.
conclusionIntroduction of a TSU was associated in a shift towards increased CT utilisation, with no increase in scan yield, increased incidental findings and impacts on Radiology workflow.
