Distribution of Bacteria and Analysis of Drug Susceptibility in Hospital Acquired Pneumonia Patients / 中华医院感染学杂志

ABSTRACT

OBJECTIVE To study the features of isolated bacteria from sputum specimens in the patients with hospital acquired pneumonia (HAP). METHODS Identification of bacteria specimen and drug sensitivity test were performed in specimens from the lower respiratory tract of patients with HAP from Jan 2007 to Dec 2007. The test results and clinical data were analyzed. RESULTS There were 136 patients with HAP,among them the old persons who were more than 60 years old and 75% of them were infected much more than others. The main pathogens were Gram-negative bacilli (57.62%). CONCLUSIONS Gram-negative bacilli are the major pathogens with high resistance rate and the multi pathogen infection is increasing and difficult to control. To decrease the infection rate,it is necessary to use antibiotic reasonably and control high risk factors.
