Abstract:

 Objective    To study the status and development tendency of nosocomial infection in the patients of a provincial integrated hospital and to provide a basis for taking effective preventive and control measures. Methods    Everyday the nosocomial infection case report card was completed according to nosocomial infection cases screened by specialized staffs and the cases diagnosed by clinical physicians in different departments . The surveillance data were analyzed by software SPSS11.5. Results    A total of 38195 inpatients were screened from January 2008 to December 2009. Nosocomial infection was found in 630 inpatients (647 times), and the infection rate and infection times rate were 1.65% and 1.69% respectively. The upper respiratory tract was the most common infection site (38.79%) and ICU was the department with the highest infection rate (32.34%). Gram-negative bacteria were the majority of pathogens for nosocomial infections. The main pathogens included Pneumonia subspecies of Klebsiella pneumoniae, P seudomonas aeruginosa and Staphyloccocus aureus. Conclusions    During the surveillance period, the distribution and pathogens of nosocomial infection in this hospital were similar to the results of related reports. And there was no outbreak of severe nosocomial infection. Some measures should be taken to effectively reduce the occurrence of nosocomial infection.
