Abstract

VILLAMARIN-BELLO, Beatriz et al. Bloodstream infections associated with central venous catheters in intensive careunits in 2 hospitals in Galicia (Spain) . Infect. [online]. 2016, vol.20, n.2, pp.62-69. ISSN 0123-9392.  https://doi.org/10.1016/j.infect.2015.07.006.

Background: Healthcare-associated infections lead to a high proportion of the adverse effects that patients experience during medical care. Among them, central-line associated bloodstreaminfections (CLABSIs) represent a significant proportion (14-52%). Objective: To calculate the incidence rates of CLABSI and to identify the risk factors for infection at intensive care units at 2 hospitals (hospital A and hospital B). Design: This study was conducted at two Galician hospitals (Spain) and was designed as an observational study that included patients attended in intensive care units from 2009 to 2011.We calculated incidence rates and risks related with intrinsic or extrinsic factors. Results: The incidence rates found at hospital A were 3.21, 2.91 and 5.76 bloodstream infections per 1,000 days at risk in 2009, 2010 and 2011, respectively, and at hospital B 2.10, 0 and4.74 bloodstream infections per 1,000 days at risk in those same years. The risk factors identified in the multivariate analysis were coma (OR = 3.72; 95% CI 1.06-13.02) and the number of catheters (OR = 1.90; 95% CI 1.21-2.97). Conclusion: The observed incidence rates are higher than the recommended standards. Intensive care unit staff should focus special attention on to patients with coma and with a high numbers of catheters.
