Active Screening of Multi-Drug Resistant Bacteria Effectively Prevent and Control the Potential Infections

Our objective is to determine if actively screen the multi-drug resistant bacteria (MDRB) infection in intensive care unit (ICU) to prevent, control, and decrease the infection rate and transmission of MDRB. The patients admitted in ICU of one hospital in 2013 were analyzed. The throat swab, blood, defecation, and urine of patients were actively collected for bacteria cultures to screen Pseudomonas aeruginosa , Klebsiella pneumoniae , Escherichia coli , Staphylococcus aureus , and Acinetobacter baumannii in patients. All patients received screening of MDRB infection and colonization within 2 days and after 2 days of admission, the results showed that there were 418 infectious bacterial strains in total and P. aeruginosa was the main bacterium. The asymptomatic infection rates of P. aeruginosa , K. pneumonia , E. coli , S. aureus , and A. baumannii were 39.02, 24.74, 44.00, 29.17, and 33.33 %, respectively; the symptomatic infection rates were 60.98, 75.26, 56.00, 70.83, and 66.67 %. 59.70 % patients received antibiotics treatment, 27.45 % patients received trachea cannula, 32.95 % patients received mechanism ventilation, 2.27 % patients received arterial cannula or venous cannula and 4.00 % patients received indwelling urinary catheters. The main MDRB in ICU is P. aeruginosa . The active screening of MDRB infection and colonization can provide the opportunity to take the life-saving measure against MDRB and treat patients. This can decrease the infection risk and the nosocomial transmission of MDRB.
