Cross⁃sectional study of nosocomial infection among inpatients in a tertiary hospital in Chengdu, 2020
Abstract
ObjectiveTo investigate the prevalence of nosocomial infection among inpatients in a tertiary hospital, and provide scientific evidence for hospital infection control and targeted surveillance.MethodsA cross-sectional survey was conducted to investigate a total of 543 hospitalized patients using the hospital information system.ResultsThe prevalence of hospital-acquired infection (HAI) was 4.24%, and that of community-acquired infection (CAI) was 23.39%. HAI prevalence differed significantly among the departments (χ2=148.870, P<0.05), and was highest in the department of intensive care medicine (72.73%). Sites of infection were significantly different between HAI and CAI (χ2=22.942, P=0.011); however, the most frequent site of infection was lower respiratory tract in both HAI and CAI. Major pathogens for nosocomial infection were Gram-negative bacteria (56.92%), mainly Escherichia coli and Klebsiella pneumoniae. Antimicrobial usage was observed in 31.68% of the patients, principally for therapeutic use of antibacterial drugs (80.23%) and a combination of drugs (88.95%). Examination rate of pathogens following the antimicrobial usage was 72.08%.ConclusionThe investigation on the prevalence of nosocomial infection may facilitate fully understanding the nosocomial infection. It warrants strengthening the monitoring in the departments of intensive care medicine and on multi-resistant bacteria, and achieving antimicrobial stewardship, so as to improve the awareness of hospital infection control in medical staff' and effectively reduce the occurrence of nosocomial infection.
