Objective To understand the current status of nosocomial infections in a municipal medical unit, to find problems in daily monitoring, and to provide the evidence for the prevention and control of nosocomial infection in high-risk groups and procedures. Methods According to the 2013 survey requirements made by the nosocomial infection control center of Chengdu, we made a cross-sectional survey about nosocomial infection among all the inpatients on July 25th, 2013 and statistically analyzed the results. Results Totally, 1 301 cases were actually investigated within 1 307 inpatients of the time (the actual investigation rate was 99.54%). The prevalence rate of nosocomial infection was 3.38% (44 cases). The top five departments of infection rate were Respiratory Intensive Care Unit (RICU), Center of Intensive Care Unit (CICU), Department of Neurosurgery, Department of Thoracic Surgery and Department of General Surgery. The main site of infection was respiratory tract, which took possession of 62.25%. In univariate analyses, age≥60, length of hospital stay >2 weeks, invasive operation, history of diabetes, operation, radiotherapy/chemotherapy, utilization of antibiotics were found to be risk factors for infections. Multivariate analysis showed that length of hospital stay (OR=3.115, P=0.001), invasive operation (OR=14.930, P<0.001), diabetes mellitus (OR=2.157, P=0.046), radiotherapy/chemotherapy (OR=7.497, P<0.001) were independent risk factors for nosocomial infections. The utilization rate of antibiotics was 45.73%. Among them, there was 85.21% using single antibiotics, and 82.18% of them were used therapeutically. Conclusion Understanding the current status of nosocomial infection in municipal hospitals helps us grasp the key and difficulty of infection control, make out prevention-control measures for high-risk groups and high-risk departments, and guide and supervise its implementation in clinical departments, which points out the direction to further reduce the incidence of nosocomial infection.
