ObjectiveIn recent years, changes have occurred in the setting of bacteriemia related with the use of vascular catheters (BVC) and with the appearance of multiresistant gram positive cocci (MR-GPC), knowledge of the limitations regarding the antibiotics used most for their treatment (glycopeptides) and the appearance of new antibiotics active against these pathogens. This article analyzes the evolution of the rates, etiologies and markers of multiresistance of the most common pathogens in the BVC (including the primary bacteriemias) in the Spanish Intensive Medicine Departments (ICU).Material And MethodsA multicenter, prospective, observational study of incidence, with voluntary participation, was conducted. A total of 74, 105, 112 and 121 ICUs belonging to 71, 97, 103 and 112 hospitals, respectively, collaborated including the years 2005-2008. The information included in the ENVIN-HELICS registry was used.ResultsThe rates of this complication have decreased and are now at about 5 episodes per 1,000 days of central venous catheter (CVC). One third of the episodes occur with significant systemic response (severe sepsis or septic shock). The MR-GPC were the most frequent, however Gram-negative bacilli (GNB) were identified in 30% of the cases and fungi (different species of Candida) in 6%. Staphylococcus epidermidis and coagulase-negative, methicillin-resistant staphylococci (CNS) persist in a proportion greater than 80%, while methicillin-resistance S. aureus have decreased to less than 40%.ConclusionsThe empirical treatment in situations of extreme seriousness should consider coverage of the most frequent pathogens such as the MR-GPC and GNB and in special conditions, the fungi.Copyright © 2009 Elsevier España, S.L. y SEMICYUC.
