Targeted monitoring of central venous catheter related bloodstream infection and risk factor analysis in the emergency intensive care unit

Abstract

Objective To investigation the incidence of central venous catheter related bloodstream infection (CRBSI) and the distribution of pathogens in patients in the emergency intensive care unit (EICU) , and analyze the risk factors of central venous catheter related bloodstream infection. Methods Clinical materials of the patients with central venous catheters in the emergency intensive care unit in Peking Union Medical College Hospital from April 2015 to March 2016 were collected. The indwelling of central venous catheters and the infection situation were investigated with the self-designed central venous catheter monitoring table. Results From April 2015 to March 2016, 108 cases of catheters were indwelled in EICU. The total number of days of central venous catheter indwelling was 688 days. There were 9 cases of CRBSI. The incidence of CRBSI was 13.08‰. There were 66.67% of catheters inspected. The gram-negative bacterium infection was the main pathogen of hospital infection. The main CRBSI risk factors were whether contaminated dressings were changed in time and timely removing unnecessary catheters. Conclusions Long term continuous targeted monitoring, timely understanding of infection related factors, and taking timely appropriate preventive measures can effectively reduce the incidence of catheter related bloodstream infection.
