Effect of quantitative assessment of nosocomial infection management in normalized prevention and control phase of the COVID-19 pneumonia epidemic

ABSTRACT

OBJECTIVE To evaluate the implementation of normalization prevention and control measures for the COVID-2019 epidemic by quantitative assessment, and to evaluated the effectiveness of epidemic prevention and control and its impact on the quality of nosocomial infection management. METHODS The infection control measures of Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology were summarized and refined them into 16 quantitative assessment indicators, which will be inspected and assessed throughout the hospital from from Jul. to Dec. 2020. Data on epidemic prevention and control, incidence of nosocomial infection, hand hygiene related data during the same period were collected. RESULTS No confirmed cases of novel coronavirus pneumonia were found, and no asymptomatic infection cases were found to infect others. The incidence of nosocomial infection from July to December 2020 decreased compared with the same period in 2019. Stratified analysis showed that the infection of upper respiratory tract, urinary tract and gastrointestinal tract were significantly reduced, while there was no significant change in the infection rate of the type I incision surgical sites, the incidence of intravascular catheter related bloodstream infection, the incidence of ventilator-associated pneumonia and the incidence of catheter-related urinary tract infection. The compliance of hand hygiene, the accuracy of hand hygiene and the standard rate of hand disinfectant consumption were significantly improved, while there was no significant change in the consumption of dry hand tissue and hand sanitizer. CONCLUSION Quantitative assessment can effectively evaluate the implementation of normalized prevention and control measures of epidemic situation. The timely detection and elimination of potential epidemic hazards will have a positive impact on the improvement of the quality of nosocomial infection management.
