Analysis of the prevalence rate of healthcare-associated infection in comprehensive hospitals of Yunnan Province from 2020 to 2022
Objective To understand the current situation of healthcare-associated infection(HAI)in comprehensive hospitals with a number of beds≥900,and provide a reference for the next step in formulating HAI prevention and control measures.Methods The data on the prevalence rate of HAI in comprehensive hospitals with-a number of beds≥900 of Yunnan Province between 2020 and 2022 were retrospective collected.The HAI situation and trend in each year were analyzed.Results A total of 119 comprehensive hospitals were included,with 166 745 patients surveyed and 3 237 cases of HAI.Lower respiratory tract infection and urinary tract infection were the most common sites.The department with the highest incidence of hospital infections was the intensive care unit,followed by neurosurgery and hematology.The prevalence rates of HAI showed a downward trend from 2020 to 2022(2.08％vs.1.99％vs.1.79％,x2=14.301,P＜0.001).A total of 1 315 strains of hospital-acquired pathogens were detected,all of which were mainly Gram-negative bacteria,with Escherichia coli and Klebsiella pneumoniae being more common.The rate of antibiotics use and the rate of pathogen testing showed an upward trend from 2020 to 2022(x2=79.233,23.866,P＜0.001),the infection rate of incision site and the prophylactic use rate of antimicrobial drugs in patients with class Ⅰsurgery both showed a decreasing trend(x2=15.551,6.311,P＜0.05).Conclusions The prevalence of infection in comprehensive hospitals of Yunnan Province is decreasing.But the supervision of key departments,the implementation of pathogen prevention and control measures,and the rational use of antibiotics in inpatients are still the focus of future work.
