Risk factors for colonisation and infection with multidrug-resistant Pseudomonas aeruginosa in intensive care unit: a systematic review and meta-analysis
Abstract
Background: There are currently two opposing hypotheses regarding the risk factors for acquisition, colonisation and infection with multidrug-resistant Pseudomonas aeruginosa (MDR-PA) in the intensive care unit (ICU). Acquisition could be either endogenous or exogenous or both. It is of great interest to estimate pooled prevalence and describe individual and environmental factors associated with the colonisation and infection with MDR Pseudomonas aeruginosa in intensive care units.
Methods: This systematic review was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The protocol of this review has been registered under CRD42021233832 in the International Prospective Register of Systematic Reviews (PROSPERO) and has been published on Systematic review on November 2022All types of studies carried out in intensive care units (ICUs) were included. MEDLINE (Pubmed), EMBASE (OVID), the Cochrane Library (Wiley), Web of Science, CINAHL (EBSCOHost), LILACS (BIREME), Google Scholar and Open Grey were searched from 1983 to 2023 and the results of electronic searches were uploaded to Rayyan software. The methodological quality of the studies was assessed using the National Heart, Lung, and Blood Institute Critical Appraisal Tools. The I2 test was performed to assess the statistical heterogeneity among the included studies. The publication bias was assessed by using the funnel plot and Egger's test. Descriptive analysis and…
