Is anyone familiar with the study mentioned in the OHSU Education presentation of monthly tips on this site? The tip "Scrub the Hub" references a study from 2007 done at Sharp memorial in San Diego regarding 15 sec of friction. I am trying to find the article but no author or title is given.
Thanks

The Kaler and Chin study is probably the one referenced, although those authors are now stating they would do that study very differently if it were to be repeated. There is also another new study on this issue:
1. Simmons S, Bryson C, Porter S. "Scrub the Hub" Cleaning Duration and Reduction in Bacterial Load on Central Venous Catheters. Critical Care Nursing Quarterly. 2011;34(1):31.
This was another in vitro study assessing the passage of organisms through a variety of needleless connectors after 5, 10, and 15 seconds. Although 15 seconds was better than the others, organisms were found passing through with all scrubbing times. This leaves me to wonder if any length of manual scrubbing is going to be effective in removing all organisms. These studies have only been conducted in a laboratory setting. There have been no studies corellating scrubbing time to a reduction in CRBSI or CLABSI. That is why the CDC guidelines only changed the word "wipe" to "scrub" and did not include a length of time for this scrubbing. Lynn
