Notes: χ2 test or Fisher’s test was used for comparing discontinuous variables and Mann–Whitney U-test was used for comparing continuous variables. **p<0.01, ***p<0.001. Statistic source data can be found in original data. Patients with invasive devices or skin barrier damage on admission (p=0.002) and those who used antibiotics before admission (p<0.001) were more likely to be colonized or infected by CRE. There was no significant association between the Xpert test results and the outcome (p=0.412).
