A study comparing the aerobic bacterial bioburden associated with surgical scrub attire shows significantly greater contamination among home-laundered attire than scrubs laundered by the healthcare facility, scrubs sent out by the facility to a third-party company for laundering, or single use/disposable scrubs. In fact, home-laundered scrubs cleaned and ready to wear had as much bacteria present as facility-laundered, third-party laundered and single-use scrubs which had been worn for one day.
Conducted in the spring of 2009, the study was performed by Bioscience Laboratories, Inc., of Bozeman, Mont., and sponsored by Molnlycke Health Care U.S., LLC. A total of 80 surgical scrub garments, tops and bottoms, prior to use and after use in the operating room for a day, were collected from multiple healthcare facilities across the U.S. They comprised 10 sets of scrubs in each category: single-use; home-laundered; facility-laundered; and third-party laundered.
The study showed no statistically significant difference in bacterial contamination among facility-laundered, third-party laundered or single-use scrubs prior to use (“clean”), but revealed that the bioburden found on home-laundered scrubs prior to use (“clean”) was significantly greater than on any of the other garments (facility-laundered, third-party laundered or single-use, non-woven) that had been worn for a day in the operating room.
