Objective To understand the characteristics of and risk factors for nosocomial infection in a newly built branch of a university teaching hospital, in order to investigate the control measures for prevention and control of nosocomial infection.
Methods A total of 598 cases of nosocomial infection from April 2012 to June 2014 were enrolled in this study. We analyzed statistically such indexes as nosocomial infection rate, infection site, pathogen detection, and use of antibiotics. Meantime, infection point-prevalence survey was introduced by means of medical record checking and bedside visiting.
Results Among all the 44 085 discharged patients between April 2012 and June 2014, there were 598 cases of nosocomial infection with an infection rate of 1.36%. Departments with a high nosocomial infection rate included Intensive Care Unit (ICU) (9.79%), Department of Orthopedics (2.98%), Department of Geriatrics (2.62%), and Department of Hematology (1.64%). The top four nosocomial infection sites were lower respiratory tract (45.32%), urinary tract (13.21%), operative incision (8.86%), and blood stream (8.86%). The samples of 570 nosocomial infections were delivered for examination with a sample-delivering rate of 95.32%. The most common pathogens were acinetobacter Baumanii (17.02%), Klebsiella pneumoniae (14.21%), Escherichia coli (13.68%), Pseudomonas aeruginosa (11.93%), and Staphylococcus aureus (9.12%). And urinary tract intubation (42.81%), admission of ICU (28.60%), and application of corticosteroid and immunosuppressive agents (26.42%) were the top three independent risk factors for nosocomial infection.
Conclusion General and comprehensive monitoring is an effective method for the hospital to detect high-risk departments, factors and patients for nosocomial infection, providing a theoretical basis for prevention and control of nosocomial infection.
