Abstract:
OBJECTIVE To collect the data regarding postoperative pneumonia(POP)in recent ten years,analyze the epidemiological rules and understand the distribution of major pathogens causing the POP so as to lay solid foundation for fully implementing' Infection Control in Surgery' initiative.METHODS The clinical data were col-lected from the patients who received surgical procedures in Chongqing University Fuling Hospital from 2015 to 2024.The difference in the incidence of POP between the sexes and among the departments and incidence trends a-mong the age groups and the years as well as the distribution of major pathogens were retrospectively analyzed.RESULTS The total incidence of POP was 1.41%in 2015-2024,2.82%in 2015,showing a year by year downward trend from 2021 to 2024(x2=284 906,P<0.001).The incidence of POP of the male was 2.42%,higher than 0.70%of the female(P<0.001).The incidence of POP was 0.29%in the 1 day to 19-year-old age group,2.84%in the 60-year-old age group,and the incidence showed an upward trend with the increase of age(x2=451.053,P<0.001).The incidence of POP varied in the departments(P<0.001),with the highest(20.24%)in the neurosurgery department,the lower(0.05%and 0.06%)in the gynecology department and oph-thalmology department.Of the isolated pathogens causing POP,Acinetobacter baumannii accounted for 25.48%,Klebsiella pneumoniae 22.82%,Pseudomonas aeruginosa 14.35%.The percentage of the A.baumannii strains was highest in all the years except for the percentage of K.pneumoniae in 2015 and 2018.CONCLUSIONS The in-cidence of hospital-associated POP is relatively low.The population of advanced age and male is at high risk of POP.POP is highly prevalent in neurosurgery department.The gram-negative bacteria are dominant among the pathogens causing the POP.
