Abstract
Objectives: To describe the characteristics and the problems arising from the use of vascular catheterization in a general hospital and to identify avoidable risk factors associated with catheter-related infections. Design: Cross-sectional, including the entire hospitalized population. Setting: A university-affiliated hospital. Results: Three-hundred fifty-three intravascular catheters were implanted in 315 of a total of 1,838 hospitalized patients (17.1%, confidence interval [CI] = 15.7-18.5). Of the 353 intravascular catheters, 26 (7.3%) were intra-arterial, 273 (77.3%) were peripheral, and 54 (15.3%) were central. The median (range) duration of the catheterization was 3 (1-11) days for arterial catheters, 1 (1-24) for peripheral catheters, and 5 (1-130) for central catheters. Fifty-three (15%, CI = 11.5-19.5) showed signs of infection. Independent risk factors associated with infection were the presence of infection located elsewhere (odds ratio [OR] = 8.7, CI = 4.13-18.3, p
