Abstract

Although there are many studies about catheter related infection in industrialized countries, very few have analyzed it in emerging countries. The aim of our study was to determine the incidence, microbiological profile and risk factors for catheter-related bloodstream infection (CRBSI) in a Tunisian medical intensive care unit. Over eight months (1 January 2012-30 August 2012) a prospective, observational study was performed in an 18-bed medical surgical intensive care unit at Tunis military hospital. Patients who required central venous catheter (CVC) placement for a duration greater than 48 h were included in the study. Two hundred sixty patients, with a total of 482 CVCs were enrolled. The mean duration of catheterization was 9.6 ± 6.2 days. The incidence for CRBSI and catheter colonization (CC) was 2.4 and 9.3 per 1000 catheter days, respectively. Risk factors independently associated with CRBSI were diabetes mellitus, long duration of catheterization, sepsis at insertion and administration of one or more antibiotics before insertion. The mortality rate among the CRBSI group was 21.8%. The predominant microorganisms isolated from CRBSI and CC episodes were Gram negative bacilli. All Gram negative organisms isolated among dead patients in CRBSI group were Extensive Drug Resistant (XDR). In our study the mortality rate among patients with CRBSI was high despite a low incidence of CRBSI. This high rate can be explained by the high-virulent status of Gram negative bacteria involved in CRBSI.
