The epidemiology of multidrug-resistant bacteria colonization and analysis of its risk factors in intensive care unit / 中华危重病急救医学

ABSTRACT

ObjectiveTo screen the colonization of multidrug resistant organisms (MDROs) and determine their risk factors in intensive care unit (ICU), so as to provide the basis of prophylaxis and treatment of MDROs colonization.Methods A prospective single-center study was conducted in ICU of China-Japan Friendship Hospital from June 2008 to December 2014. The nostril and anal swabs for each patient who stayed in ICU over 24 hours were collected. Each specimen was cultured and tested for drug sensitivity. Clinical findings and relative risk factors were collected. The risk factors of MDROs colonization were analyzed with univariate analysis. The independent risk factor was selected from the risk factors withP 9 days (OR = 1.766, 95%CI = 1.235 - 3.986,P = 0.021) were independent risk factors of MDROs colonization on admission to ICU.ConclusionsHigh prevalence of MDROs colonization in ICU patients was found in our hospital, and ESBL enterobacteria was the predominant bacteria. ICU acquired MDROs colonization is also worth considering, especially for MDR-AB. Identification of risk factors for MDROs colonization may help identify and screen patients with high risk, and it is also instructive in prophylaxis of MDROs colonization/infection and restriction of the use of broad spectrum antibiotics.
