INTRODUCTION: Although central venous catheters (CVCs) provide reliable vascular access, there are several risks linked with their use, with the rates of central-line-associated bloodstream infections (CLABSIs) being the most important ones. CLABSIs have a big impact on mortality rates and health care costs. The aim of this study was to investigate the incidence of obesity in the development of central venous catheter infections. MATERIAL AND METHOD: This is a prospective, observational study. The data were collected in the ICUs of three major hospitals in Greece, over a period of 18 months. Totally, 744 patients were included in the study. RESULTS: The study included 744 ICU patients aged 63.6 ± 16.6 years. The Apache II score and MODS score of patients were 23.3 ± 6.9 and 7.5 ± 3.8, respectively. Totally, 5.426 catheter-days were included in the study. Among the 722 CVCs, 178 (24.7%) were CLABSIs. The incidence rate of CVC-associated CLABSI was 22.48 infections per 1000 catheter-days. CLABSI was significantly predicted by the BMI (p = 0.001), by the diabetes mellitus as comorbidity (p = 0.013), by the doctors' experience (p = 0.001), by the type of CVC (p = 0.001) and CVC site (p = 0.001), by the number of efforts for CVC insertion (p = 0.009), by the catheterization's duration (p = 0.001) and by the MODS score (p = 0.001). CONCLUSIONS: Better staff training focused on care bundles preventing infections, better medical training focused on less efforts for CVC insertion, and the use of Ultrasounds during the CVC insertion may be the main factors that can lead to lower CLABSI rates in obese patients. Further research relating CLABSI rates in ICU patients and obesity is needed.
