Trial Outcomes & Findings for Hub Cleansing to Prevent Hub Infection (NCT NCT01563406)
NCT ID: NCT01563406
Last Updated: 2016-04-18
Results Overview
This will be a qualitative outcome. It will be reported as "yes" or "no" for central venous catheter hub internal contamination. The number of hubs with internal contamination will be compared for the four study arms.

Participant Flow
140 participants were recruited through 149 separate medical intensive care unit (MICU) admissions. Each MICU admission is treated as a separate enrollment.
Two separate wings of a 24-bed MICU were randomized to receive different intervention sequences. Wing A was assigned to a 15 sec scrub of 1) Alcohol; 2) chlorhexidine gluconate (CHG)+Alcohol; 3) Alcohol; and Wing B was assigned to a 5 sec scrub of 1) CHG+Alcohol; 2) Alcohol; 3) CHG+Alcohol.

PRIMARY outcome
Timeframe: 15 monthsPopulation: 140 participants were recruited through 149 separate medical intensive care unit (MICU) admissions. Each MICU admission is treated as a separate enrollment.
This will be a qualitative outcome. It will be reported as "yes" or "no" for central venous catheter hub internal contamination. The number of hubs with internal contamination will be compared for the four study arms.
Outcome measures

Alcohol, 15 Second Scrub
n=194 Hubs
Each catheter hub was disinfected before each access by scrubbing with 70% isopropyl alcohol alone for 15 sec.
|
Chlorhexidine+Alcohol, 15 Second Scrub
n=30 Participants
Each catheter hub was disinfected before each access by scrubbing with 3.15% chlorhexidine gluconate(CHG)/70% isopropyl alcohol for 15 sec.
|
Alcohol, 5 Second Scrub
n=101 Hubs
Each catheter hub was disinfected before each access by scrubbing with 70% isopropyl alcohol alone for 5 sec.
|
Chlorhexidine+Alcohol, 5 Second Scrub

SECONDARY outcome
Timeframe: 10 monthsPopulation: Unable to collect a sufficient number of catheter tips to analyze. Therefore, this outcome was dropped early in the study.
This will be a qualitative measure for central venous catheter tip contamination. The results will be reported as "yes" or "no".
Outcome measures
Outcome data not reported
SECONDARY outcome
Timeframe: 15 monthsThis will be a quantitative outcome. It will be reported as the median number of microbial colony forming units isolated per hub interior. The median number of microbial colony forming units isolated per hub interior will be compared for the four study arms.
