OBJECTIVE To investigate the current status of hospital-associated infections,distribution of infection cases in departments,infection sites and pathogens so as to achieve the rational allocation of resources and provide data support for continuous improvement of medical quality.METHODS From 2019 to 2023,the relevant data in-cluding the departments of hospitalized patients with the infections,time of infections,infection sites and patho-gens were collected from all of the infection patients of Hohhot First Hospital by Xinglin nosocomial infection teal-time monitoring system and were statistically analyzed.RESULTS There were 1802 cases of hospital-associated infec-tions in total from 2019 to 2023,and the average incidence rate of infection was 1.18％.The average incidence of hospi-tal-associated infections exceeded 3％in 6 of 36 departments from 2019 to 2023(584 cases in total,accounting for 32.41％among all the cases),and the incidence of hospital-associated infections showed an upward trend in intensive care unit(ICU)(x2=4.125,P=0.042).The 3 major infection sites of the patients with hospital-associated infections were as follow:the patients with respiratory system infection accourted for 66.35％,the patients with urinary system infec-tions accounted for 19.39％,the patients with blood system infections 3.33％.Klebsiella pneumoniae,Escherichia coli and Acinetobacter baumannii ranked the top 3 species of pathogens causing the hospital-associated infection,accounting for 17.68％,12.25％and 11.33％,respectively.CONCLUSIONS The incidence of hospital-associated infections shows an upward trend in recent years.It is necessary to strengthen the comprehensive and meticulous management of the infec-tions and take full advantage of information surveillance data so as to further improve the medical quality and safety.
