Systematic review and meta-analysis of the prevalence and types of health care associated infections in Nigeria.
Synthesis in BMC infectious diseases, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundHealthCare-Associated Infections (HCAIs) are those infections that patients acquire while receiving treatment for other health conditions within the health facility. There is a paucity of data on HCAIs in Nigeria.
objectivesTo evaluate the prevalence and types of as well as the common organisms causing HCAIs in Nigeria. MATERIALS AND
methodsA systematic review, with meta-analysis was conducted, and the results were presented in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. PubMed, AJOL, Google Scholar and Cochrane electronic databases were searched in April 2024. Studies describing prevalence of HCAIs in Nigeria were included. Data extraction was done using pre-specified data extraction form. We performed a meta-analysis on prevalence of HCAIs and subgroup analysis on types of HCAIs in Nigeria using the random-effects model. A risk of bias tool from Hoy and colleagues was used to assess risk of bias.
resultsOut of 1899 articles searched, we included 16 studies involving 86772 participants. The pooled prevalence of HCAIs in Nigeria was 15.75% (95% CI 14.39, 17.11) and the commonest type was urinary tract infections (32.54%; 95% CI 29.44-35.64) followed by surgical site infections (22.17%; 95% CI 19.96-24.38) and skin and soft tissue infection (16.43%; 95% CI 9.42-23.43). The commonest organisms reported were Proteus species and Staphylococcus aureus, followed closely by Escherichia coli, Klebsiella and Pseudomonas. One study reported on multidrug resistance. The commonest associated risk factors were surgery, Human Immunodeficiency Virus infection, prior use of antibiotics and endotracheal intubation.
conclusionsThe findings of this research unveil a significant prevalence of HCAIs in Nigeria, standing at 15.75%. Urinary tract infections, surgical site infections, and skin and soft tissue infections were the most prevalent. Proteus species and Staphylococcus aureus were identified as the predominant organisms. This review indicates a scarcity of data concerning the risk factors for HCAIs and associated multidrug-resistant infections. Included studies mainly used isolation of microbial organisms to define HCAIs. These gaps underscore the need for further research in these critical areas within the country's healthcare settings.
