Healthcare-associated infections in Chinese neonates: a multicenter retrospective period prevalence survey in Jiangsu Province (2023).
Article in BMC infectious diseases, 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
backgroundHealthcare-associated infections (HAI) pose a significant threat to neonates, especially preterm and critically ill infants, leading to prolonged hospitalization, increased healthcare costs, and elevated mortality. Understanding the epidemiological characteristics of neonatal HAI is crucial for guiding the development of targeted public health policies and clinical prevention strategies. This study aimed to investigate the epidemiology of neonatal HAI in Jiangsu Province, China, in 2023.
methodsA retrospective period prevalence survey was conducted in Jiangsu Province, China, from September to October 2024. Data on neonatal HAI occurring between January and December 2023 were collected using a structured questionnaire. Thirty hospitals (30/39, 76.9% response rate) from all 13 cities ultimately participated and completed the survey.
resultsAmong 36,957 neonates (327,098 patient-days), 370 HAI episodes were identified, yielding a prevalence of 1.0% (95% CI: 0.9–1.1%). Neonates with a birth weight < 1500 g had a significantly higher risk (RR = 17.0, 95% CI: 14.0–20.8; p < 0.001). Multivariable linear regression at the hospital level identified the proportion of neonates with birth weight < 1500 g as the sole independent factor associated with HAI rates (β = 0.062, p = 0.016), while infection preventionist staffing levels showed no significant association. The most common infection sites were bloodstream (44.1%), lower respiratory tract (17.4%), and gastrointestinal tract (5.5%). Predominant pathogens included coagulase-negative staphylococci (18.2%) and Klebsiella pneumoniae (17.2%). Device-associated infection rates were 0.7‰ (95% CI: 0.4–1.0) for central line-associated bloodstream infection and 1.2‰ (95% CI: 0.7–1.6) for ventilator-associated pneumonia.
conclusionThis first province-wide study reveals a relatively low overall period prevalence of HAI among neonates in Jiangsu. The findings underscore that the proportion of very low birth weight neonates is a key driver of inter-hospital variation in infection rates. Prevention priorities should, therefore, focus on this high-risk population and on the predominant infection sites, particularly bloodstream infections. These efforts should be supported by strengthening microbiological surveillance.
