Healthcare-associated infection and community-acquired infection: Cross-sectional survey of 37 hospitals in Tangshan / 实用医学杂志

ABSTRACT

Objective To understand the status and the risk factors of healthcare-associated infection (HAI) and community-acquired infection (CAI) , and to provide guidance and basis for prevention and control of nosocomial infections. Methods We investigated and analyzed HAI and CAI of 37 hospitals by the cross-sectional survey method. Results 16 650 patients were investigated, the HAI occurred in 171 and 267 ases with the prevalence rate of 1.54％ and 5.24％ in the second-class and the third-class hospitals. The CAI occurred in 1 889 and 831 cases with the prevalence rate of 17.04％ and 16.31％. HAI prevalence rate in the third-class hospitals was higher than the second-class hospitals, while there was no difference in the rate of CAI. There was statistical significance in constituent of infection sites in different levels of hospitals. There was no difference in community infection. A total of 148 pathogens were isolated from patients with HAI, and the top four bacteria were Pseudomonas aeruginosa, Escherichia coli, Klebsiella pneumonia, Acinetobacter baumannii. The detection rate of multidrug-resistant bacteria were 26.32％ and 31.82％ respectively in the second-class and the third-class hospitals. The utilization rates of antimicrobial agents in the second-class and the third-class hospitals were 42.97％ and 31.82％ respectively. Pathogen detection rate in third-class hospitals was higher than that of the second-class hospitals (47.10％, 32.76％) , and the difference was statistically significant. The survey was found that the use of catheters, urinary tract catheters, ventilators and immunosuppressive agents were risk factors in hospital infection. Conclusion Hospitals should strengthen the monitoring of hospital infection and take various measures to control the rate of hospital infection.
