You see them everywhere -- nurses, doctors and medical technicians in scrubs or lab coats. They shop in them, take buses and trains in them, go to restaurants in them, and wear them home. What you can't see on these garments are the bacteria that could kill you.Ugh. It does explain something that's bothered me, though: why on earth the almost religiously-sterilized environments you see in hospitals are somehow riddled with germs.
Dirty scrubs spread bacteria to patients in the hospital and allow hospital superbugs to escape into public places such as restaurants. Some hospitals now prohibit wearing scrubs outside the building, partly in response to the rapid increase in an infection called "C. diff." A national hospital survey released last November warns that Clostridium difficile (C. diff) infections are sickening nearly half a million people a year in the U.S., more than six times previous estimates.
The problem is that some medical personnel wear the same unlaundered uniforms to work day after day. They start their shift already carrying germs such as C.diff, drug-resistant enterococcus or staphylococcus. Doctors' lab coats are probably the dirtiest. At the University of Maryland, 65% of medical personnel confess they change their lab coat less than once a week, though they know it's contaminated. Fifteen percent admit they change it less than once a month. Superbugs such as staph can live on these polyester coats for up to 56 days.
Do unclean uniforms endanger patients? Absolutely. Health-care workers habitually touch their own uniforms. Studies confirm that the more bacteria found on surfaces touched often by doctors and nurses, the higher the risk that these bacteria will be carried to the patient and cause infection.
Fortunately the solution is easy:
Can it really be that simple? Hospital-laundered scrubs that are forbidden from leaving the Hospital produce a near-zero infection rate? How is this not LAW?
Until about 20 years ago, nearly all hospitals laundered scrubs for their staff. A few hospitals are returning to that policy. St. Mary's Health Center in St. Louis, Mo., reduced infections after cesarean births by more than 50% by giving all caregivers hospital-laundered scrubs, as well as requiring them to wear two layers of gloves. Monroe Hospital in Bloomington, Ind., which has a near-zero rate of hospital-acquired infections, provides laundered scrubs for all staff and prohibits them from wearing scrubs outside the building. Stamford Hospital in Connecticut recently banned wearing scrubs outside the hospital.
Across the pond, a British study found that one-third of medical personnel did not launder their uniforms before coming to work. One British surgeon who specializes in hip and knee replacements reduced postoperative infections by two-thirds at her hospital by protecting patients from contaminated uniforms. Before approaching any patient's bed, nurses put on disposable, clear plastic aprons that were pulled off rolls like dry cleaning bags. Each one costs a nickel.
In response to this evidence and public outrage over infections, the cash-strapped British National Health Service is providing nurses with hospital-laundered "smart scrubs." The smart design includes short sleeves, because long sleeves spread germs from patient to patient.
Sure, it's the WSJ, and for all I know this is nonsense. I found the link while reading a Karl Rove piece about the mortgage crisis that blamed everything on Fannie and Freddie, for God's sake, one has to be cautious. But still.
