Effectiveness of Nurse-Led atrial Fibrillation Detection for Patients With Embolic Stroke of Unknown Source in Stroke Units: A Retrospective Study.
Article in Nursing in critical care, 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
backgroundAtrial fibrillation is a primary cause of ischemic stroke, necessitating early detection, particularly in patients with embolic stroke of undetermined source. While nurseled continuous electrocardiogram monitoring allows real-time rhythm assessment in acute stroke units, its specific clinical impact remains insufficiently clarified.
aimTo evaluate the impact of nurse-led notification of suspected atrial fibrillation in patients with cryptogenic stroke. STUDY
designA retrospective medical record review was conducted on patients with cryptogenic stroke admitted to a stroke unit between January and December 2022 in a tertiary general hospital in South Korea. Clinical characteristics and outcomes were compared based on the presence of nurse-led atrial fibrillation notifications.
resultsIn total, 235 patients were included. Nurse-led notifications for suspected atrial fibrillation occurred in 24 (10.2%) patients of whom 95.8% were confirmed to have overt atrial fibrillation. The nurse-led notification group experienced a shorter time to anticoagulation initiation (3.7 vs. 5.6 days; p = 0.015), shorter hospital stay (7.2 vs. 12.9 days; p = 0.015) and lower overall medical costs ($5889.6 vs. $8487.6; p = 0.021) among the group of newly confirmed atrial fibrillation. Nurses with ≥ 10 years of neurology experience were associated with atrial fibrillation detection (RR = 17.70, 95% confidence interval = 4.64-67.70, p < 0.001). Nurse-led notification was independently associated with reduced hospital stay (B = -5.08, 95% confidence interval = -8.33 - -1.83, p = 0.002).
conclusionsNurse-led notification of suspected atrial fibrillation was associated with shorter hospital stays and a potential benefit in the early initiation of anticoagulation. Integrating experienced nurses into structured cardiac monitoring protocols may improve the efficacy of care for patients with embolic stroke of undetermined source. RELEVANCE TO CLINICAL PRACTICE: Nurse-led atrial fibrillation detection significantly improves clinical and economic outcomes. These findings underscore the critical role of clinical expertise in cardiac monitoring, suggesting that such initiatives can optimise resource allocation and improve clinical outcomes in stroke units.
