Using a Human Factors Framework to Examine Complexity as a Mediator Between IPC Work System and Healthcare Workers' Behaviors: A Structural Equation Model.

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: Infection prevention and control (IPC) behaviors among healthcare workers are influenced by multiple components and complex features of the work system. Complexity refers to the multicomponent, non-linear, and context-dependent characteristics of system elements, and is increasingly recognized as a key feature of healthcare delivery. However, evidence on the role of IPC complexity in these relationships remains limited. Methods: A cross-sectional survey was conducted in 3 branch hospitals of a tertiary hospital in Wuhan, China. A total of 833 healthcare workers completed a structured questionnaire assessing IPC person, organization, tools and technology, tasks, internal environment, external environment, IPC complexity, and IPC behaviors based on Systems Engineering Initiative for Patient Safety (SEIPS) model. Structural equation modeling and bias-corrected bootstrap analyses were used to evaluate direct and indirect associations. Results: IPC complexity ( Conclusion: IPC behaviors were linked to multiple work system factors, with complexity serving as an important intermediate correlate. Efforts to improve IPC practice should address task demands, environmental support, and perceived work complexity rather than focusing on individual behaviors alone.
