Investigation of Nosocomial Cluster Infections of Peripheral Venous Catheter-Related Bloodstream Infection

Object: Determine the cause of nosocomial cluster infections of peripheral venous catheter-related bloodstream infection (PIVC-BSI), and provide advice on prevention, control and nursing measures. Method: A retrospective analysis of nosocomial cluster infections that occurred in a tertiary hospital on July 28-30, 2019. Blood samples from patients suspected of PIVC-BSI were retained for bacterial culture. The clinical data of the patients, environmental hygiene indicators were collected. Results: All 8 patients had chills within 0.5 - 3.5 hours after intravenous infusion, and the highest body temperature reached 41°C. The peripheral blood samples of 4 patients were cultured as Burkholderia cepacia infection, and the eluate from the catheter tip of 2 patients cultured the same bacteria as the blood culture. The humidity in the treatment preparation room was 60% - 80%. There was mold in the sterile storage cabinet. Conclusion: The nosocomial cluster infection of PIVC-BSI was caused by Burkholderia cepacia colonizing the tip of the peripheral intravenous catheter, and the high air humidity was the most likely factor. The ability of nurses to identify and respond to PIVC-BSI as well as the infection control management level of each department still needs to be improved.
