Bacterial contamination on clinical surfaces and oxygen device accessories in the emergency unit of a tertiary health facility in Ghana.
Article in BMC infectious diseases, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundNosocomial infections have gradually become an emerging threat to the healthcare system over the past decades and have been attributed to poor decontamination of hospital articles and weak antibacterial stewardship policies. This study sought to investigate the effect of disinfection on the prevalence and resistance profile of bacterial contaminants on oxygen device accessories, and clinical surfaces at the emergency unit of a tertiary health facility in Ghana.
methodsThe study employed a cross-sectional study design to evaluate the occurrence of bacteria on surfaces in a tertiary hospital. Luminal swabs of the oxygen device accessories and swabs from clinical surfaces used by healthcare providers were collected for isolation and identification of bacteria. The identified bacteria isolates were then tested for their susceptibility to antibacterial agents. Data from this study were analyzed using Excel (Microsoft Office Suite), and GraphPad Prism 8 software programs.
resultsA quarter of the total 44 bacterial isolates obtained from both post-disinfected and pre-disinfected surfaces were Gram-positive, with the remaining isolates being Gram-negative. Pseudomonas aeruginosa was the most frequent bacteria species isolated (41%) followed by Citrobacter sp. (21%). P. aeruginosa, S. aureus, and S. pneumoniae were found to be highly resistant to Chloramphenicol (36%), and Sulfamethoxazole (100%); whereas Ciprofloxacin (91%) was the most effective antibacterial drug used.
conclusionThe almost equal prevalence of multidrug-resistant bacteria from both post-disinfected and pre-disinfected surfaces of inanimate objects, and oxygen device accessories connote an ineffective disinfection process which may influence resistance in bacterial contaminants. This requires the overhaul of disinfection protocol and training of hospital staff, and rational use of antibacterial agents at the hospital to mitigating the burden of nosocomial infections.
