Impact of a Clinical Decision Support System on CT Pulmonary Angiography Yield and Utilization in Hospitalized Patients.
Article in Journal of the American College of Radiology : JACR, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
purposeThe aims of this study were to determine whether point-of-order clinical decision support (CDS) based on the Wells criteria improves CT pulmonary angiography (CTPA) yield and utilization in hospitalized patients in an enterprise-wide health system and to identify yield-related factors.
methodsThis retrospective, institutional review board-approved, cross-sectional study in an urban, multi-institution health system included hospitalized patients undergoing CTPA 12 months before and after CDS implementation (entire cohort). The χ
resultsFor 2,429 inpatient CT pulmonary angiographic examinations after the intervention, CTPA yield was significantly higher when CDS recommendations were followed (18.3% [250 of 1,365]) compared with those overridden (14.2% [151 of 1,064]) (P < .01). For 5,372 CT pulmonary angiographic examinations in the entire cohort, there was no difference in PE yield before (448 of 2,943 [15.2%]) versus after (401 of 2,429 [16.5%]) CDS implementation (P = .20). However, in 340,146 admissions over the study period, a 7.4% relative decrease in CTPA utilization (from 17.5 to 16.2 CT pulmonary angiographic examinations per 1,000 admissions before and after CDS, respectively, P = .003) was observed.
conclusionsWhen CDS recommendations were followed, the yield of CTPA was significantly higher than when clinicians overrode CDS alerts. In addition, point-of-order CDS to reduce unnecessary CTPA in hospitalized patients resulted in a significant decrease in CTPA utilization after CDS implementation, with a modest although nonsignificant increase in CTPA yield.
