Background:
Temporary hemodialysis catheters are important devices used in dialysis practice but may be the source of infection in hemodialysis patients.
Methods:
We investigated the infectious complications in 70 hemodialysis patients using 113 hemodialysis catheters.
Results:
The frequency of catheter-related bacteremia was 23.9%, of which Staphylococci were the most frequently growing organism (96.3%). Exit-site infection was observed in one patient. No cases were lost due to the infectious complications. The risk for the development of catheter-related bacteremia was increased after the 24th day of catheterization and after the second venous puncture.
Conclusions:
There was a positive correlation between hypoalbuminemia and bacteremia. Internal jugular venous catheterization and hypoalbuminemia were determined as risk factors for the development of catheter-related bacteremia. The risk factors for catheter-related bacteremia in patients with hemodialysis catheter should be determined and modified in order to decrease infectious complications.

HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.
