Overall percentages of GNB and CR-GNB isolates from the ICU environmental samples from 2019 to 2022. GNB: gram-negative bacteria; CR-GNB: carbapenem-resistant gram-negative bacteria. (a): A comparison of A. baumannii (75%, 108/144), P. aeruginosa (11.8%, 17/144) and K. pneumoniae (13.2%, 19/144) isolated from environmental samples revealed a statistically significant difference (χ2 = 168.813, p < 0.001). (b): A comparison of CRAB (80%, 72/90), CRPA (15.6%, 14/90), and CRKP (4.4%, 4/90) isolated from environmental samples revealed a statistically significant difference (χ2 = 134.800, p < 0.001).
