Introduction
Accurate surveillance definitions are necessary to evaluate the impact of interventions to prevent central line–associated bloodstream infections (CLABSIs). Although, the National Healthcare Safety Network (NHSN) definition for CLABSI has been applied extensively in intensive care units, few studies have examined its performance among bone marrow transplant (BMT) recipients. As those patients have inherent risks for bloodstream infections associated with mucosal barrier injury, more specific definitions are necessary for catheter-related bloodstream infection (CRBSI) in order to determine the impact of improvement projects to decrease these device-associated infections (DAIs).
