Abstract Objective To analyze the incidence of nosocomial infection of the elderly patients with respiratory diseases in the last three years in Zhejiang Hospital, and to explore the risk factors of infection, and to provide reference for the prevention of nosocomial infection.Methods The clinical data of 4233 cases of elderly patients with respiratory system diseases in Zhejiang Hospital from January 2015 to June 2017 was analyzed retrospectively, with 452 cases of nosocomial infection in the study group and the rest in the control group. Single factor analysis and Logistic regression model were used to analyze the risk factors of nosocomial infection. 452 patients with nosocomial infection were included in the study group, and the remaining patients were included in the control group. Single factor analysis and Logistic regression model were used to analyze the risk factors of nosocomial infection.Results A total of 572 microorganisms was detected in 452 cases of nosocomial infection, including gram positive bacteria 189(33.05%), gram negative bacteria 347(60.66%), and fungi 36(6.29%). And 394 patients(87.17%) were infected with single pathogens, and 58(12.83%) patients were with mixed infection. The three most widely distributed sites were respiratory tract(56.19%), urogenital tract(21.24%), and blood (13.05%). Logistic analysis showed that the age of 70 years old and above(OR=1.804, 95% CI:1.478~2.197), diabetes mellitus(OR=1.908, 95% CI:1.557~2.338), bedridden(OR=1.639, 95% CI:1.281~2.097), hospitalization time 2 weeks and above (OR=1.405, 95% CI:1.153~1.713), and invasive procedures(OR=1.954, 95% CI:1.579~2.419) were risk factors of nosocomial infection in elderly patients with respiratory diseases.Conclusion Patients with senile respiratory diseases aged 70 years or above, with diabetes mellitus, bedridden, hospitalization time 2 weeks and above, and invasive operation should be the focus of prevention and control.
