Distribution of Pathogens in Hospital for 3 Years

OBJECTIVE To investigate the distribution of pathogens in hospital wards and sits and their kinds in the latest 3 years,so that to make the measurement to control the infection. METHODS The samples from the in-patient department or hospital infection cases during Jan 2005 to Dec 2007 were reviewed and analyzed. RESULTS There was an obvious difference in constituent ratio among the samples' from the different wards. 42.83% secretion samples were from micro-orthopedic department,33.89% sputa samples from respiratory and neurological wards,33.36% sputa samples from neurosurgery ward,and 33.55% blood samples from burn-ward. The constituent ratio among pathogens was as follows:17.55% of Psendomonas aeruginosa 17.55% of Staphylococcus aureus,13.81 of Acinetobacter baumannii and 12.18% of Corynebacterium iminutissimum. CONCLUSIONS The number of critically trauma patients is increasing,and the bacterial distribution and site of infection are closely ralated. We should pay more attention on them,and make a reasonable choice of anti-bacterial drugs.
