This isn't really a new subject, but I haven't yet found a definitive answer. We're re-writing our policy/procedure re drawing labs and flushing central lines through positive-pressure needleless hubs(end caps). How long should the hub be scrubbed before accessing it...3 secs....5-10-15? I even saw 60 seconds in one procedure on the internet.
 5 or 10 seems like a reasonable time period. I did it for 15 seconds...and that is a VERY long time. I doubt most nurses would take that much time. What are you all doing? Are there any articles on this subject?
Thanks
The only published study that I am aware of was in JAVA's fall 2007 issue. An in vitro study using both 70% alcohol and CHG scrubbing for 15 seconds, both agents for this time were effective. I have not seen any other studies, leaving the question of will a shorter period of time be as effective with either or both of the agents. I don't think anyone actually knows the answer at this point.

There is another study that indicated that 3-5 seconds wasn't effective. That time period allowed 67% of bacteria transfer. It wasn't the intention of the study, but the info is in there.
