Abstract
Central line associated bloodstream infection (CLABSI) is a significant complication in critically ill patients undergoing catheter placement. This research was a retrospective study to determine the incidence of bloodstream infections associated with catheter placement in patients admitted to the medical intensive care unit from January 2017 - December 2022. A demographic data and diagnosis of CLABSI form was used for data collection. Data were analyzed using descriptive statistics. The results showed that there were 1868 patients with catheters; most were male. The most common catheter insertion position was a jugular vein. A total of 13 infections were found per 10,019 total catheter days. The lowest average number of catheter days was 4.6 days in 2019 and the highest 6.2 days in 2020. The highest infection rate was 1.51 times per 1,000 catheter days in 2017 and the lowest 0.63 times per 1,000 catheter days in 2022. The most common causative bacteria were gram-negative bacteria which are multidrug resistant, including Klebsiella pneumoniae and Acinetobacter baumannii. In conclusion, the incidence of infection tended to decrease continuously. Nurses should play a significant role to review the problem and search for practical preventive procedures, such as by increasing the scrub hub and using an antiseptic barrier cap, as well as by
monitoring and supervising practices.
