Contamination of hospital surfaces by third-generation cephalosporin-resistant gram-negative bacteria in district hospitals in Mwanza, Tanzania: Urgent need for enhanced infection prevention and control.

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: Hospital surfaces are critical reservoirs of multidrug-resistant pathogens, including third-generation cephalosporin-resistant Gram-negative bacteria (3GC-R-GNB), significantly contributing to healthcare-associated infections (HCAIs). This challenge is pronounced in low- and middle-income countries, where resource constraints limit effective infection prevention and control (IPC) measures. This study screened hospital surfaces for 3GC-R-GNB in selected District Hospitals (DHs) in Mwanza, Tanzania. Methods: This cross-sectional hospital-based study was conducted between June and July, 2023. Door handles, hand-washing sinks, patients' beds, and ward floors were sampled. Isolation of 3GC-R-GNB was done on MacConkey agar supplemented with cefotaxime (2 μg/ml). Bacterial identification was done by MALDI-TOF on Vitek MS while antimicrobial susceptibility testing was done by the Kirby-Bauer method. A multiplex PCR assay was applied for the detection of extended-spectrum beta-lactamase (ESBL) genes ( Results: A total of 892 swabs were collected from hospital surfaces, of which 243 (27.2%) were 3GC-R-GNB positive. From the 243 positive samples, 55 samples exhibited polymicrobial growth making a total of 300 bacterial isolates. The most prevalent species was Conclusion: This study reveals substantial dispersion of highly resistant Gram-negative bacteria to hospital surfaces, showing the need to prevent dispersion of such contamination and targeted hospital hygiene measures to protect patients.
