Abstract Objective: to determine demographic, technical and characteristics of the catheter in the development of bacteremia in patients over 15 years with central venous catheter were hospitalized in the intensive care unit of the Hospital Universitario San Vicente Fundación Medellín between 2009 and 2011, in order to generate information that contributes to implement prevention strategies. Method: cross-sectional observational study case-control analysis in intensive care units, using a database of the Hospital Universitario San Vicente Fundación collected from 2009-2011. Cases were defined as patients with a diagnosis of bacteremia associated with central venous catheter as controls patients with central venous catheter without bacteremia. A total of 66 patients were analyzed (22 cases and 44 controls), with a 1:2 ratio. We sought association or relationship between variables with chi-square test of Pearson x2, Fisher or Yates correlation, as the number of observed and expected cell, and Mann-Whitney test for comparison of medians. Results: It was found in the multivariate analysis a significant association with the indication of drug administration and hemodynamic monitoring (OR = 12.14, 95 = 1.03 to 110.237) and concomitant administration of parenteral nutrition (OR = 4.5; 95 % CI = 0.586 to 34.873). Conclusions: The variables associated with central venous catheter bacteremia were: the administration of medications and concomitant hemodynamic monitoring TPN.
