Abstract：Objective To survey the prevalence rate of nosocomial infection in a specialized hospital for geriatric diseases in Guangxi from 2013 to 2022,and analyze the results.Methods An annual survey on nosocomial infection was conducted in Jiangbin Hospital of Guangxi Zhuang Autonomous Region every year from 2013 to 2022.All the clinically hospitalized patients were selected as the survey subjects from 0:00 to 24:00 on a certain day in July.The survey subjects included the patients who were discharged from the hospital or transferred to other hospitals on the survey day,and those who were admitted to the hospital were excluded from the survey on the same day.The data of nosocomial infection monito-ring and management in each year were retrospectively analyzed and summarized.Results From 2013 to 2022,among the 11 078 patients receiving the survey,223 cases of nosocomial infection occurred,totaling 234 times in 223 cases.The overall prevalence rate of the nosocomial infection was 2.01％(223/11 078),and the incidence rate of 234 times in 223 cases was 2.11％(234/11 078).The rate of infection times in infected cases was highest in 2014(3.72％),and lowest in 2021(1.14％),showing an overall downward trend.The clinical department with the highest prevalence rate of nosocomial infection was the Department of Respiratory Medicine(13.44％),and the infection site was mainly in the lower respiratory tract,followed by the urinary tract,upper respiratory tract and gastrointestinal tract.A total of 190 strains of pathogenic bacteria were in the infected patients detected in this survey,including 135 strains of Gram-negative bacteria(71.05％),44 strains of Gram-positive bacteria(23.16％)and 11 strains of fungi(5.79％).The results of multivariate logistic regression analysis showed that age ≥ 65 years[OR(95％CI)=1.790(1.345-2.382),P＜0.001]and use of antibiotics[OR(95％CI)=1.912(1.445-2.530),P＜0.001]were independent risk factors for the nosocomial infection(P＜0.05).Conclusion The prevalence rate of nosocomial infection in the hospital shows a downward trend,and the prevention and control work of nosocomial infection in the hospital has achieved certain results.However,it is still necessary to strengthen managements for key departments,susceptible infection sites and high-risk populations.
