Classifying nursing roles in critical infectious disease care: a multicenter cross-sectional study using cluster analysis.

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
Aim: To classify nursing roles in the care of critically ill patients with infectious diseases based on clinical practice patterns and nurse characteristics, and to describe the features of each role type to provide empirical evidence for optimising human resource allocation and enhancing care efficiency. Design: A multicenter cross-sectional survey study. Methods: Between February and March 2025, 275 nurses providing direct care to critically ill patients with infectious diseases were recruited from multiple tertiary hospitals across diverse geographic regions. Data were collected using a self-developed, semi-structured interview-informed questionnaire assessing the frequency of 80 specific nursing activities, alongside demographic and workload information. Hierarchical cluster analysis followed by K-means clustering was applied to identify latent nursing role types. The differences of each type were further compared by univariate analysis and multiple logistic regression analysis. Results: Three core domains of nursing practice were identified: clinical nursing care, advanced clinical specialty skills, and nursing management/professional development. Accordingly, three distinct nursing role types: Comprehensive Development Type -high engagement across all domains; Management and Coordination Type -primarily focused on administrative and coordination tasks with minimal direct patient care; and Clinical Task Execution Type-predominantly delivering routine basic care with limited involvement in advanced or managerial activities. These types differed significantly in age, professional experience, formal position, weekly workload, and intention to leave the role. Multiple regression analysis showed that traditional variables such as age and professional title had no significant independent predictive effect on distinguishing comprehensive development type from clinical task execution type; Age is the qualification threshold of management coordination. Conclusion: Nursing roles in critical infectious diseases care form an informal but functionally stratified hierarchy shaped by career progression and organisational demands, yet lack formal recognition. This empirically derived typology supports precision-based staffing, role clarification, and targeted retention strategies. Aligning job expectations with actual practice can reduce burnout-particularly among early-career nurses performing high-volume basic tasks-and strengthen team resilience during public health emergencies. Findings inform the development of flexible, evidence-based role frameworks that enhance both workforce sustainability and patient safety.
