Bloodstream infections among patients using central venous catheters in intensive care units

Abstract

Central Venous Catheters (CVC), widely used in Intensive Care Units (ICU) are important sources of bloodstream infections (BSI). This prospective cohort epidemiological analytical study, aimed to infer the incidence of BSI, the risk factors associated and evaluate the care actions related to the use of these catheters in seven ICU in the Federal District - Brasília, Brazil. From the 630 patients using CVC, 6.4% developed BSI (1.5% directly related to the catheter and 4.9% clinic BSI). The hospitalization term was 3.5 times greater among these patients. Different modalities of catheter insertion and antiseptic substances use were observed. Time of CVC permanence was significantly associated to infection incidence (p<1x10-8) as well as the right subclavian access and double-lumen catheters. Patients with neurological disorders and those submitted to tracheotomy were the most affected. We suggest the organization of a "catheter group" aiming to standardize procedures related to the use of catheters in order to reduce the hospitalization term and hospital costs.
