Discrete event simulation and agent-based modelling of distributed situation awareness in patient flow management.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Patient flow management heavily relies on effective communication or transactions of situation awareness (SA) amongst hospital staff to minimize patients' length of stay. Modelling SA transactions quantitatively could help identify inefficiencies and test potential solutions. This paper presents quantitative modelling of distributed situation awareness (DSA) with discrete event simulation (DES) and agent-based modelling (ABM) to capture and assess the transactions and distribution of SA for intrahospital transportation in patient flow management. The quantitative model was built on a qualitative DSA combined network for intrahospital transportation, observations, and historical data, followed by validation with t-tests by comparing transport time and number of patients transported between model outputs and historical data. Further, the model was used to test two proposed interventions for eliminating SA deficiencies revealed by prior qualitative DSA research: (1) updating the charge nurse before picking up patients, and (2) updating the X-ray unit before arriving. T-tests on the simulation results of 1500 replications revealed that the first intervention yielded significant reductions in mean transport time and cancelation rate, while the second intervention yielded a significant increase in transport time compared to the historical operational data. To our knowledge, this work is the first quantitative modelling research on DSA that is being assessed against operational data. The findings affirm that DSA is a promising framework for analyzing communication and coordination in complex systems and assessing system-level SA quantitatively.
