The evaluation of effectiveness of implemented actions to limit intravascular catheter-related bloodstream infection rates. We have analyzed actions taken in nineteen wards in the St. Lukas District Hospital in Tarnów. During seven-year study period, from 2005 to 2011, 207 673 hospitalized patients were supervised. A study was done among all patients with peripheral intravenous catheters and central venous catheters. Standard statistic tools and definitions of nosocominal infections used by US Centers for Disease Control and Prevention were used. Intravascular catheter-related bloodstream infection rates has been calculated by a formula: (number of catheter-related bloodstream infections/number of person-days with catheters) x1000. During the period study, decrease in frequency of occurrence was obtained: venous catheter-related bloodstream infections decreased from 2.8 to 0.4 per 1000 person-days, central venous catheter-related bloodstream infections decreased from 8.9 to 3.0 per 1000 person-days, peripheral intravenous catheter-related bloodstream infections decreased from 0.6 to 0.3 per 1000 person-days. The most common causative agent of venous catheter-related bloodstream infections was in 44% of cases Staphylococcus CNS and in 19% of cases Staphylococcus aureus. It is possible to significantly decrease intravascular catheter-related bloodstream infection rates by taking preventive actions combined with intensive education of medical personnel.
