Bacterial contamination of physicians’ newly laundered uniforms occurs within three hours of putting them on, making them no more or less dirty than the traditional white coats, researchers reported.
Researchers sought to compare bacterial and methicillin-resistant Staphylococcus aureus contamination of physicians’ white coats to freshly laundered short-sleeved uniforms, and to determine the rate at which bacterial contamination happens. They reported results in the Journal of Hospital Medicine.
ACP Internist‘s blog recently took up the debate as well. The issue has cropped up over the years, assessing not only the cleanliness but the professionalism inherent in the white lab coat.
Researchers conducted a prospective, randomized, controlled trial among 100 residents and hospitalists on an internal medicine service at Denver Health, a university-affiliated public safety-net hospital. Subjects wore a white coat or a laundered, short-sleeved uniform.
At the end of an eight-hour workday, no significant differences were found between the extent of bacterial or MRSA contamination of infrequently-washed white coats compared to the laundered uniforms. Sleeve cuffs of white coats were slightly but significantly more contaminated than the pockets or the midsleeves, “but interestingly, we found no difference in colony count from cultures taken from the skin at the wrists of the subjects wearing either garment,” researchers wrote.
And, there was no association found between the extent of bacterial or MRSA contamination and the frequency with which white coats were washed or changed. Colony counts of newly laundered uniforms were essentially zero, but after three hours they were nearly 50 percent of those counted at eight hours.
Drunk driving continues to be a serious problem. In 2009 for example, alcohol was a factor in more than 10,000 highway deaths. The same year, a stunning 10 percent of respondents to a survey of U.S. adults said they had operated an automobile while drunk during the previous year. Nearly 6 percent said they had done it more than once.
So how would you feel about a car that can instantly detect whether a driver is drunk and prevent that person from starting the car? You better make up your mind quickly, because scientists are close to perfecting this technology.
“We’re five to seven years away from being able to integrate this into cars,” Robert Strassburger, the VP for safety at the Alliance of Automobile Manufacturers (AAM) told the Washington Post. The AAM, an automotive trade group, is on the development team for the new technology which is being spearheaded by the Automotive Coalition for Traffic Safety and National Highway Traffic Safety Administration.
The anticipated sensing device will look nothing like the breathalyzer machines currently used by police in the field. Instead it will be comprised of tiny, passive, touch-sensitive sensors that are permanently affixed to a key fob or a starter button. The sensors can determine blood alcohol levels in seconds.

In November 2010, the California Department of Consumer Affairs (DCA) finally decided to act responsibly and forbid the prevalent practice of Chinese bloodletting by licensed acupuncturists. The practice became a concern for the DCA when allegations of unsanitary bloodletting at a California (CA) acupuncture school surfaced.
The incident allegedly occurred during a “doctoral” course for licensed practitioners. The instructor was reportedly demonstrating advanced needling and bloodletting techniques. During the process, he took an arrow-like lancing instrument that is called a “three-edged needle” (三棱针), sharpened it with sandpaper, cleaned it with alcohol, and then asked a student-volunteer to roll a towel around his neck. The instructor then cleaned the student’s temporal region with alcohol, and punctured a superficial blood vessel with the arrow-like instrument. The student then held his head over the garbage can, gushing blood for awhile. Read more »
“Floods, tsunamis, earthquakes, cyclones – the WHO South-East Asia Region is particularly vulnerable to natural disasters. In 1996-2005, such events led to the deaths of more than half a million people in this region. This makes up 58% of the total number of people killed worldwide due to natural disasters.
Hospitals are lifelines in the aftermath of a disaster, when large numbers of people are critically injured or vulnerable. It is particularly vital that they remain intact and functional to save lives. In addition to treating disaster victims, hospitals must also quickly resume treatment of everyday emergencies and routine care. When hospitals are damaged or destroyed during disasters, it has a social, economic as well as health impact. Hospitals and health facilities are at the core of the structure of every community. They also protect health workers and the most vulnerable people – the sick – all the time. When these are damaged, it can have a psychological impact on the entire community. Read more »
It’s no secret that doctors are disappointed with the way that the U.S. healthcare system is evolving. Most feel helpless about improving their work conditions or solving technical problems in patient care. Fortunately one young medical student was undeterred by the mountain of disappointment carried by his senior clinician mentors…
I am proud to be a part of the American Resident Project an initiative that promotes the writing of medical students residents and new physicians as they explore ideas for transforming American health care delivery. I recently had the opportunity to interview three of the writing fellows about how to…
I m often asked to do book reviews on my blog and I rarely agree to them. This is because it takes me a long time to read a book and then if I don t enjoy it I figure the author would rather me remain silent than publish my…
When I was in medical school I read Samuel Shem s House Of God as a right of passage. At the time I found it to be a cynical yet eerily accurate portrayal of the underbelly of academic medicine. I gained comfort from its gallows humor and it made me…
I am hesitant to review diet books because they are so often a tangled mess of fact and fiction. Teasing out their truth from falsehood is about as exhausting as delousing a long-haired elementary school student. However after being approached by the authors’ PR agency with the promise of a…
