Infection Control in Healthcare

We evaluated the impact of increasing the interval between routine central venous catheter exchanges from every 3 days to every 4 days on the rate of catheter infections and catheter-related bacteremia. Computer records of catheter tip and blood culture results in burn patients were reviewed. The change to every 4 day catheter exchange occurred in November 2000 and data were collected until June 2001. One hundred and ninety-six guidewire exchanges were performed in the every 3 day (q3day) group, and 164 guidewire exchanges were performed in the every 4 day (q4day) group. The rate of catheter infections (>15 colony forming units) was 11% in the q3day group and 28% in the q4day group. Catheter-related blood stream infection occurred in 4% of patients in q3day group and 12% of patients in q4day group. A prospective review of this change in practice revealed that there was a significantly greater risk of infections in the q4day group. The increase in infected central venous catheter segments was associated with an increase in blood stream infections.
