Abbreviation: CRBSI, catheter-related bloodstream infection.

^aThe catheter-days were calculated based on the number of CRBSI and incident rate. For example, in [13], catheter days = 1000 × 134 / 2.61.

^bRate was reported as 5.2 bloodstream infections (BSIs) per 1000 hemodialysis sessions in control period in [17]. In a similar study by Taylor et al, hemodialysis sessions averaged 1 per 2.41 patient days (28.81 per 10000 hemodialysis procedures / 11.97 per 10000 patient-days) [19]. Thus, we converted 5.2 BSIs per 1000 hemodialysis sessions to 2.16 (ie, 5.2 / 2.41) BSIs/patient-days.
