Abstract:
Objective To study characteristics of hospital infection and bacterial drug-resistance in our new Intensive Care Unit (ICU) to provide evidence to clinical rational use of drugs. Methods The data of 142 patients in our ICU last year were analyzed retrospectively, and compared to other inpatients treated in general ward during the same time period. Results Among the 142 ICU inpatients,31 times of hospital infection occurred in 22 patients,gave rise to a infection rate of 15.49% and case time infection rate of 21.83% in ICU; but among the 15 978patients treated simultaneously in general ward,413 times of hospital infection occurred in 324 inpatients, gave rise to a infection rate of 2. 03% and case time infection rate of 2. 58% outside of ICU. The hospital infection rate and case time infection rate were significantly different between the ICU and general ward (P ＜ 0. 01 ). Among the ICU infections, the lower respiratory tract infection accounted for 70. 96% ;the main pathogens were Gram-negative bacilli (65. 12% ) and Gram-positive bacilli (23.26%), follwed by fungus (11.63%). The most common bacteria were Escherichia ( 32. 65% ) and Staphylococcus ( 11.63% ). Gram-negative microorganisms were highly sensitive to cefoperazone/sulbactam,imipenem, meropenem and piperacillin/tazobactam; all Gram-positive microorganisms were sensitive to vancomycin,linezolid and teicoplanin. Conclusions The constitution,distribution and drug-resistance of pathogens in new ICU are similar to previous domestic reports. Gram-negative organisms are the main photogenic bacteria of hospital infection in ICU, and Escherichia is the most popular type in nosocomial infection.
