In order to analyze the risk factors of nosocomial infection in the use of reusable medical devices, a retrospective analysis was made of 370 original data of biological monitoring of reusable medical devices filed in the Hospital Infection Department from January 2018 to December 2018. The possible risk factors in the use of reusable medical devices and the corresponding preventive measures were analyzed. The data were compared with 340 original data of air organisms from January 2017 to December 2017. The qualified rate of surveillance, surface biology and manual surveillance were compared. By analyzing the use of reusable medical devices in hospitals in 2018, it was found that the main risk factors of nosocomial infection were air pollution, surface pollution of objects and hand pollution of staff. After taking active and effective preventive measures, the qualified rates of air biological monitoring, surface biological monitoring and hand monitoring of staff in 2018 were significantly higher than those in 2017. There was statistical significance (P < 0.05), and the satisfaction rate of doctors and nurses with reused medical devices was 98.86% after the implementation of preventive measures, which was significantly higher than 89.77% before the implementation. The experiment result shows that the air environment around the reusable medical devices, the surface of the carrying objects and the staff all have certain risk factors of inducing infection. It is necessary to strengthen the training and supervision of infection in order to effectively prevent the occurrence of nosocomial infection.
