ABSTRACT

Introduction. Surveillance is necessary for bloodstream infection control. Daily monitoring of the central venous catheter (CVC) use, a time-demanding process, is the standard denominator to calculate the infection rate; surveillance of only one day per week has been proposed as alternative. Objective. To determine whether surveillance of one day per week is similar to daily monitoring in a second-level hospital. Material and methods. Daily monitoring of CVC utilization ratio was done during nine weeks in four locations of a second-level hospital. For each day, proportional differences respect to the global CVC utilization ratio was estimated. An ANOVA test was done to find differences between each weekday. Results. CVC usage surveillance was performed for 9 weeks, so nine determinations were obtained for each weekday. No significant differences were found between each day (F = 2.20, p = 0.056). The lowest sampling discrepancy was found on Wednesdays. Conclusions. According to previous studies, and our own data, monitoring the CVC use one day per week is a reasonable alternative to the daily surveillance.
