摘要

This study is to analyze patients’ characteristics, the distribution of services, the infection sites, the trend of infection, and to compare the difference of nosocomial MRSA infections between ICU and NON-ICU. From 1989 to 1994, S. aureus was the most common nosocomial pathogen, during which the percentage of MRSA infections rose from 41% in 1989 to 86.3% in 1994, with total infections of 1190. The major distribution of patients by medical services in order were: Medicine, surgery, and pediatrics. The major infected sites in order were: Bloodstream, lower respiratory tract, and surgical wound. The major different risk factors for nosocomial MRSA infections between ICU and NON-ICU were arterial catheter (odds ratio=30.5), SWAN-GANZ catheter (odds ratio=16.5) and ventilator (odds ratio=5.6). The antimicrobial resistance of S. aureus rose yearly. Among all the antibiotics, the resistence to the Vancomycin is the lowest, with an average rate of 1.7%. With significantly increased prevalence, nosocomial MRSA infections have becomed one of the most important problems in the hospitals. To control and prevent the infections, the following interventions are recommended: Establishing policy, in-service education, isolation techiques, antibiotics usage control, and shortening the duration of hospitalization.
