In multivariate analysis, prior steroid use (OR: 3.22, 95% CI: 1.36–7.66, p < 0.01), prior use of two or more antibiotics (OR: 4.04, 95% CI: 1.40–11.71, p = 0.01), prior use of extended-spectrum cephalosporins (OR: 2.40, 95% CI: 1.06–5.44, p = 0.04), and prior use of carbapenem (OR: 4.77, 95% CI: 1.17–19.35, p = 0.03) were the independent risk factors for the infection of CP-CRE. Here, CP is linked to infection.
