When and How Grid-Based Information Management for VTE Prevention: Boundary Conditions and Configurational Pathways from a Mixed-Methods Study.
Article in Journal of multidisciplinary healthcare, 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
Background: Venous thromboembolism (VTE) is a significant cause of preventable morbidity and mortality among hospitalized patients. Although grid-based information management systems have shown effectiveness in VTE prevention, the boundary conditions and configurational pathways leading to optimal outcomes remain unclear. Objective: To investigate the impact mechanism of grid-based information management on VTE prevention effectiveness, identify boundary conditions of moderating effects, and explore configurational pathways leading to high prevention outcomes. Methods: A mixed-methods study design was employed. A total of 119 hospitalized patients from Affiliated Hospital of North Sichuan Medical college were enrolled between January and December 2024, with 58 patients in the control group (traditional management) and 61 in the intervention group (grid-based information management). The Johnson-Neyman (J-N) technique was used to identify the boundary conditions of nurses' VTE knowledge and departmental collaboration on intervention effectiveness. Fuzzy-set qualitative comparative analysis (fsQCA) was employed to identify configurational pathways leading to high VTE prevention outcomes. Results: The intervention group demonstrated significantly higher VTE risk assessment completion rates (86.9% vs 63.8%, absolute difference 23.1%, 95% CI 8.7-37.5%, P<0.01), prevention measure implementation rates (90.2% vs 58.6%, absolute difference 31.6%, 95% CI 17.2-46.0%, P<0.01), and lower VTE incidence (3.3% vs 8.6%, absolute risk reduction 5.3%, 95% CI 0.4-10.2%, NNT=19, 95% CI 10-250, P=0.032). J-N analysis revealed that the positive effect of grid-based information management on VTE risk assessment became significant when nurses' VTE knowledge scores reached ≥42 points (P<0.05), and the effect on prevention measure implementation became significant when departmental collaboration scores reached ≥3.4 points (P<0.05). FsQCA identified three configurational pathways leading to high VTE prevention outcomes: technology-driven, collaboration-driven, and comprehensive support pathways, with an overall solution consistency of 0.892 and coverage of 0.684. Conclusion: Grid-based information management effectively improves VTE prevention outcomes, but its effectiveness is contingent upon nurses' knowledge levels and departmental collaboration. Multiple equifinal pathways exist to achieve high VTE prevention outcomes, providing evidence for tailored implementation strategies.
