The impact of hospital volume on CT usage in the management of pediatric empyema.
Article in Pediatric surgery international, 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
introductionThe American Pediatric Surgical Association (APSA) recommends reserving chest computed tomography (CT) for severe pediatric empyema, though specific criteria remain vague. Adherence to these guidelines across hospitals is unclear. We hypothesized that lower-volume centers more frequently deviate from guidelines, particularly through increased CT utilization, without improved outcomes.
methodsUsing the Pediatric Health Information System (PHIS), we identified patients aged 3-18 with empyema admitted between 2016-2023 who underwent chest tube placement or video-assisted thoracoscopy (VAT) within 3 days of admission. Patients with abscess, gangrene, other complications, or open thoracotomy were excluded. Forty-eight hospitals were stratified into low-, medium-, and high-volume terciles by total empyema case volumes. Multivariable logistic and Poisson regression models adjusted for demographic and clinical factors.
resultsAmong 1,698 patients, mean 8-year case volumes were 16.5, 30.1, and 75.9 for low-, medium-, and high-volume hospitals, respectively. High-volume hospitals had 52% lower odds of early chest CT use (OR = 0.48; 95% CI: 0.34-0.68; p < 0.001). Hospital size and presence of a pediatric surgery fellowship were not associated with CT utilization. Length of stay, antibiotic duration, ICU admission, 30-day readmission, and mechanical ventilation did not differ by hospital volume.
conclusionsHigher-volume centers demonstrate greater adherence to APSA guidelines with lower chest CT utilization, without differences in disease severity or clinical outcomes.
