Controlling nosocomial transmission of respiratory infections in neurological wards: insights from COVID-19 pandemic data.
Article in International journal for quality in health care : journal of the International Society for Quality in Health Care, 2025. 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
backgroundTransmissible diseases pose significant risks within healthcare facilities, which can lead to accelerated viral spread and exacerbate healthcare burdens, particularly for patients with severe conditions. During the COVID-19 pandemic, numerous cases of nosocomial infections were reported, underscoring the shortcomings of current in-hospital management strategies for controlling such outbreaks. This study aims to provide insights for developing improved in-hospital management strategies for future infectious disease outbreaks.
methodsComprehensive data on the infection status and clinical profiles of all patients and healthcare staff, gathered during the COVID-19 outbreak at a Shanghai brain hospital, were analyzed to evaluate transmission dynamics and identify risk factors. Machine learning techniques were utilized to recognize infection factors, while time series analyses-including cross-correlation and Granger causality tests-were performed to explore temporal relationships.
resultsThe infection rate within the hospital significantly exceeded that of the surrounding community, confirming a heightened risk of nosocomial transmission. Notably, peak infections among healthcare workers lagged behind those among patients, with time series analysis revealing a clear patient-to-worker transmission pathway within hospital wards. Furthermore, a machine learning prediction model trained on all patient data demonstrated high accuracy in predicting (Area under curve = 1.00 for training set and 0.85 for testing set) susceptible individuals and successfully identified risk factors such as age, doctor number in ward, red blood cell count, etc.
conclusionThe study elucidated a distinct patient-to-worker transmission pattern of respiratory infectious diseases in healthcare settings and identified critical susceptibility risk factors. These findings provide valuable strategic guidance for managing and mitigating future nosocomial outbreaks, ultimately enhancing infection control and preparedness in hospital environments.
