Abstract

Background: Timing of central venous catheter (CVC) insertion among patients with acute leukemia is debatable. Early insertion increases convenience, but might increase infection rates.

Methods: We assessed retrospectively the rate of central line-associated bloodstream infections (CLABSI) according to CVC time of insertion in patients with acute leukemia admitted for induction or salvage therapy. The study was conducted in the Hematology Department of a Tertiary hospital in Israel between 2007 and 2011. Early CVC placement was defined as CVC inserted during the first week of induction therapy. CLABSI rate was documented between the seventh day of induction therapy to 30 days after its completion.

Results: A total of 127 patients were included. Acute myeloid leukemia was the most common diagnosis (103 patients, 80.5%). Late CVC placement was associated with CLABSI after adjustment to the Charlson comorbidity index (OR 3.4, 95% CI 1.1-10.45), p=0.03.

Conclusion: Delaying CVC placement in adult patients with acute leukemia may be associated with higher rate of CLABSI in the early period after induction therapy.
