Monitoring and Analysis of the Distribution of Multidrug-Resistant Bacteria in a Tertiary Hospital From 2021 to 2022
Objective To analyze the distribution of multidrug-resistant orgnism in different departments,different populations and different infection states in a tertiary hospital from January 2021 to December 2022.Methods The multidrug-resistant orgnism sent for detection in inpatients from January 2021 to December 2022,Chifeng Municipal Hospital were grouped according to the category,gender and infection status of the department,and the distribution was analyzed.Results From January 2021 to December 2022,a total of 883 cases of multidrug-resistant bacteria were detected,of which the most detected were extended spectrum beta-lactamase(ESBLs),accounting for 31.37%.The distribution of multidrug-resistant orgnism was different in different categories of departments(χ2=220.448,P<0.001),and ESBLs were the main ones in internal medicine wards and surgical wards,and carbapenem resistant Acinetobacter baumannii(CR-AB)was mainly in intensive departments,and the differences were statistically significant(P<0.05).The distribution of multidrug-resistant orgnism was also different in different genders(χ2=57.994,P<0.001),the majority of male patients were mainly CR-AB,181 cases were detected,while the majority of female patients were ESBLs bacteria,131 cases were detected,the difference was statistically significant(P<0.05).The distribution of multidrug-resistant orgnism in different infection types was also different(χ2=74.391,P<0.001),and the difference was statistically significant,ESBLs account for the largest proportion of patients with community infections,while CR-AB was the main in patients with nosocomial infection.Conclusion The distribution of multidrug-resistant orgnism is widespread,and the distribution is different,and the prevention and control work should be strengthened,and targeted measures should be taken to prevent and control nosocomial infection of multidrug-resistant bacteria.
