It also is among the most prevalent nosocomial infections, largely due to the widespread use of urinary catheters in hospitalized patients. These catheters often act as reservoirs for multidrug-resistant bacteria, including extended-spectrum beta-lactamase- and carbapenemase-producing pathogens, which significantly limit treatment options and delay appropriate care. This systematic review and meta-analysis, therefore, aimed to assess the pooled prevalence of ESBL- and carbapenemase-producing Gram-negative bacteria associated with UTIs in Ethiopia.</p><p><strong>Methods: </strong>A systematic literature search of all available electronic databases such as PubMed, Hinari, Google Scholar and EMBASE, Scopus, and African journal online was performed. The quality of the included studies was assessed via the Joanna Briggs Institute critical appraisal tool. The data were extracted from the eligible studies via Microsoft Excel 2019 and analysed via STATA version 17. The presence of between-study heterogeneity was checked via the Cochrane Q statistic, and the magnitude was quantitatively measured via I² statistics. To determine the possible sources of heterogeneity, a subgroup analysis was performed. Additionally, a sensitivity analysis was conducted to determine the influence of single studies on the pooled estimates. Publication bias was checked via funnel plots and Egger's regression tests. A p value of less than 0.05 was evidence of heterogeneity and small study effects according to the Cochrane Q statistic and Egger's test, respectively.

In this meta-analysis, the pooled prevalence of extended-spectrum beta-lactamase- and carbapenemase-producing Gram-negative bacteria was significantly high.
