title: Laboratory-based surveillance of hospital-acquired catheter-related bloodstream infections in Catalonia. Results of the VINCat Program (2007-2010).
abstract: The VINCat Program is an institutional surveillance program for hospital-acquired infections developed in the healthcare institutions of Catalonia, Spain. The program includes the monitoring of various components of hospital-acquired infection, among which is catheter-related bloodstream infection (CRBSI). The aim of this study was to describe the frequency of CRBSI in hospitals participating in the VINCat Program over a period of 4 years (2007-2010). The monitoring of the CRBSI component is carried out continuously in all inpatient units by performing a daily assessment of all blood culture results issued by the Microbiology Laboratories. Precise definitions are used for CRBSI, and adjusted rates are expressed per 1,000 days of hospitalization, hospital size and type of catheter. The rates of CRBSI in catheters used for parenteral nutrition are adjusted and expressed per 1,000 days of device use. The aggregate data of the total period are shown in percentiles (10%, 25%, 50% or median, 75%, and 90%). From 2007 to 2010, a total of 2977 episodes of CRBSI were reported in 40 hospitals participating in the VINCat Program. The cumulative incidence of CRBSI has been 0.26 episodes per 1,000 days of hospitalization (CI95% 0.2 to 0.3). The overall incidence varied depending on hospital size: 0.36 ‰ for hospitals in Group I (>500 beds), 0.17 ‰ for Group II (200-500 beds), and 0.09 ‰ for Group III (<200 beds). 76% of the episodes were associated with central venous catheters (CVC), 19% of the episodes with peripheral venous catheters (PVC), and the remaining 5% with peripherally inserted CVCs (PICC). The most common organisms causing CRBSI were staphylococci, the group Klebsiella, Serratia and Enterobacter, Candida spp., and Pseudomonas aeruginosa. There are important differences in the etiology of CRBSI in relation to these variables. During the reporting period, a significant reduction (38.1%, CI95%, 29.0-46.0%) of CRBSI rates have been observed in Group I hospitals. CRBSI surveillance is an important element of the VINCat Program, offering to us the possibility of establishing standard values for this component and implementing intervention strategies for its reduction.
