Abstract:
Objective The aim of this study is to analyze the characteristics and risk factors of community-acquired infectious pathogens in our hospital's outpatient and emergency department from 2020 to 2022, in order to develop targeted prevention and control measures. Methods A retrospective analysis of 17 423 pathogen specimens from patients with community-acquired infections admitted to the outpatient and emergency departments of our hospital from January 2020 to December 2022 was conducted. Detailed information about the infection site was recorded, and the etiological characteristics and influencing factors were analyzed. Results From 2020 to 2022, the specimens sent for inspection in our hospital mainly included blood, sputum and urine, with a total of 6 613 non-duplicate pathogenic strains detected, yielding a detection rate of 37.95%. The top five detected pathogenic organisms were Escherichia coli (19.16%), Klebsiella pneumoniae (9.56%), Acinetobacter baumannii (7.38%), Candida albicans (7.35%), and Staphylococcus aureus (6.77%). Among them, the detection rate of Escherichia coli showed a decreasing trend year by year (2=13.051, P=0.001), while the detection rate of Acinetobacter baumannii showed an increasing trend year by year (2=24.392, P<0.001). Multivariate Logistic regression analysis showed that age ≥60 years, presence of underlying diseases,invasive medical procedures within 1 month, skin injuries within 1 month, history of hemodialysis within 3 months, and History of antibiotic use within 3 months were independent risk factors for community-acquired infections in our hospital. Conclusion From 2020 to 2022, the main pathogens causing community-acquired infections in our hospital were Gram-negative bacteria. In view of the specific distribution of pathogenic species and infection risk factors, clinicians should implement more targeted prevention and control measures against relevant risk factors.
