Objectives: To evaluate that "patient days" could be a substitute of "catheter days" to be used as a denominator in surveillance of peripheral venous catheter related blood stream infections (PCRBSI).
Methods: In a single acute care tertiary hospital, from April 2012 to September 2015, we assessed the correlation of patient days and catheter days using a Pearson correlation. We compared changes of PCRBSI rates by month between using patient days as a denominator versus using catheter days.
Results: The mean of patient days per month was 20,320, and the mean of catheter days per month was 11,178. Patient days were strongly correlated with catheter days (r=0.851, P<0.01). Monthly trends of PCRBSI rates were almost identical using both metrics as the denominator.
Conclusions: These findings suggest that patient days and catheter days are equally useful for the evaluation of PCRBSI rates in a hospital where peripheral venous catheters are frequently used.
