Objective To investigate the prevalence rate of nosocomial infection in West China Hospital of Sichuan University and to analyze the implementation effect of nosocomial infection control measures, so as to provide reference for infection control.Methods An investigation of the prevalence rate of nosocomial infections was performed on patients who were admitted in West China Hospital of Sichuan University from 0:00-24:00 on a day of every late June from 2012 to 2018 by using bedside investigation in combination with inpatient medical record query, and the data was verified, summarized, and statistically analyzed by the professionals of Nosocomial Infection Management Department.Results From 2012 to 2018, the prevalence rates of nosocomial infections were 5.19%, 4.20%, 3.94%, 4.26%, 4.29%, 4.25%, and 2.97% in West China Hospital of Sichuan University, which tended to decline (χ²=32.826, P<0.001). There was no significant difference in annual total infection rate in the Department of Internal Medicine, however, the infection rate in the Department of Hematology tended to decline (χ²=6.127, P<0.05); in the Department of Surgical Medicine, the total infection rate tended to decline(χ²=18.721, P<0.001); in particular, the infection rate in the Department of Thoracic Surgery tended to decline(χ²=3.906, P<0.05); the annual difference in infection rate in the Intensive Care Unit (ICU) was not statistically significant. The key site of nosocomial infection was dominated by the lower respiratory tract, and the annual difference was not statistically significant. In particular, postoperative pneumonia has increased since 2014 (χ²=9.56, P=0.002). The nosocomial pathogens which had the highest constituent ratio over the years were Acinetobacter baumannii (in 2012, 2013, 2014, 2017, and 2018), Klebsiella pneumonia (in 2015), and Escherichia coli (in 2016). The annual difference in rate of antimicrobial use was not statistically significant(χ²=3.75, P=0.053), while the rate of antimicrobial use in the ICU tended to decline (χ²=30.42, P=0.000).Conclusions The prevalence rate of nosocomial infection in West China Hospital of Sichuan University tends to decline. However, sufficient attention still requires to be paid to lower respiratory tract infection, particularly for patients with postoperative pneumonia.
