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 months

Population: 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.

Chlorhexidine+Alcohol, 15 Second Scrub
n=102 Hubs
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
n=112 Hubs
Each catheter hub was disinfected before each access by scrubbing with 3.15% chlorhexidine gluconate(CHG)/70% isopropyl alcohol for 5 sec.
Number of Central Venous Catheter Hubs With Internal Contamination
42 contaminated hubs
18 contaminated hubs
39 contaminated hubs
14 contaminated hubs

SECONDARY outcome

Timeframe: 10 months

Population: 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 months

This 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.
