BACKGROUND AND OBJECTIVES: Central line associated bloodstream infection (CLABSI) is associated with high rates of morbidity and mortality. This study was conducted to determine the occurance of central venous catheter(CVC) related infections in our hospital and to identify the factors affecting it. STUDY DESIGN: This was a prospective, observational study carried out in St. Martha's hospital over a period of 2 years (2013 & 14). A total of 55 patients with indwelling central venous catheters for at least 3 days were included. Patients with established source of infection or taking anti-retroviral therapy were excluded. Catheter tips and peripheral blood were cultured. RESULTS: Total 51 patients with CVCs were studied for bacteriology. Of them, 41 (80.4%) patients had negative catheter tip culture and also negative blood cultures. A total of 10 (19.6%) patients developed microbial growth on catheter tip culture but negative for blood culture. They were classified as having catheter associated infection mostly due to contamination from insertion site infection. No patient developed catheter-associated bacteremia. No morality was attributable to catheter associated infection. Occurance of infection was high among patients who required multiple attempts during catheterization, less frequent times dressing changed, associated with local site infection (erythema, purulence, tenderness or induration) and increased WBC counts from baseline. As we avoided femoral vein for catheterisation, IJV was the commonest site associated with infection. Sixty percent of the isolates belonged to the CONS group. CONCLUSIONS: Occurrence of CVC related infection was 19.4%. The high rate of infection is a matter of concern to our hospital setup. We would like to use subclavian vein as preferential site for cathete rization. We have given importance to frequent change of dressings and look forward to improve skill of central venous catheter insertion.
