Why carry out this study?

Catheter management strategies for suspected catheter-related bloodstream infection (CRBSI) remain a major challenge.

There is an urgent need to develop strong practical evidence to identify CRBSI for prevent unnecessary catheter removal and subsequent harm to patients.

To knowledge the attributable mortality of CRBSI is important that a key factor to the decisions made regarding the suspected CRBSIs management strategy in patients, but it is remains uncertain.

Why carry out this study?

This initial model based on the SIRS criteria is relatively better at identifying patients with CRBSI but only in domains of the sensitivity.

There were no significant differences in attributable mortality due to CRBSI and other causes in patients with suspected CRBSI, which prompt catheter removal and re-insertion of new catheter may not benefit patients with suspected CRBSIs.
