Trial Outcomes & Findings for Ethanol Lock Therapy for Treatment and Secondary Prophylaxis of Central Line-Associated Bloodstream Infection (NCT NCT01472965)

NCT ID: NCT01472965

Last Updated: 2017-11-13

Results Overview

Therapeutic failure was a pre-defined composite outcome comprising either 'early failure': central line removal, death, persistent positive blood cultures for \>72 hours, development of new CLABSI, or initiation of other ALT) during the 5 day treatment phase, or 'late failure': relapse (new CLABSI with an identical organism), or reinfection (new CLABSI with a different organism) during the 24 week prophylaxis phase. The percentage of evaluable participants with therapeutic failure is reported.

Participant Flow

Participants meeting eligibility criteria were enrolled between December 2011 and August 2016. They were randomized to receive catheter lock therapy using either 70% ethanol or heparin-saline (placebo). Randomization was blinded to the participant, their care provider, the investigator, and the outcomes assessor.
