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

objectiveThe YEARS criteria combine D-dimer testing and clinical features (hemoptysis, signs of deep vein thrombosis, and pulmonary embolism as the most likely diagnosis) to risk stratify patients with symptoms of pulmonary embolism who may undergo CT pulmonary angiography in the emergency department (ED). Electronic clinical decision support can optimize CT pulmonary angiography utilization in EDs, yet its effectiveness with the YEARS criteria remains unstudied. Our goal is to increase the percentage of CT pulmonary angiograms performed with a D-dimer by 10% within six months of integrating the YEARS criteria into our electronic ordering system.

methodsSingle centre quality improvement initiative for all ED patients > 18 years investigated for pulmonary embolism with a D-dimer and/or CT pulmonary angiogram between Jan 2022 - Jan 2023. An electronic clinical decision support algorithm was created based on the YEARS criteria and a plan-do-study-act cycle was completed. Using an SPC chart, the percentage of CT pulmonary angiograms ordered with a D-dimer was identified. Process measures included the rate of CT pulmonary angiograms ordered, the rate of imaging ordered in accordance with the YEARS criteria, and diagnostic yield of imaging based on YEARS status. Balancing measures included pulmonary embolism identified on CT pulmonary angiogram with a D-dimer < 500 ug/L FEU or within 30 days of index visit after being ruled out with the YEARS criteria.

resultsOver 12 months, 2639 patients were investigated for pulmonary embolism and 906 underwent CT pulmonary angiogram. The percentage of CT pulmonary angiograms ordered with a screening D-dimer increased by 14.5% (63.8%, CI 59.5-68.1% vs 78.4%, CI 74.4-82.3%) without increasing the rate of imaging ordered (34.9%, CI 32.4-37.4% vs 33.7%, CI 31.1-36.3%). The YEARS criteria were properly applied in 60% (255/425) of patients who underwent CT pulmonary angiogram. The diagnostic yield of CT pulmonary angiogram was higher if patients were YEARS positive (13.2%, CI 9.0-17.4) compared to YEARS negative (0%, CI 0-28.3) or if not applied (8.1%, CI 3.9-12.4). There were two missed pulmonary embolisms at baseline and none post-intervention.

conclusionsImplementation of the YEARS criteria using electronic ordering assistance increased the percentage of CT pulmonary angiograms ordered with a D-dimer without increasing imaging use in the ED.
