"Washing one hand washes the other, washes a hand," it is the lesson 20 years ago Ra-Tim-Bum Castle tried to teach Brazilian children. Apparently the little song did not reach the American doctors. A new survey conducted by the Hospital Santa Clara Valley Medical Center, USA, pointed out that the hygiene of health professionals is far from ideal.
According to the study (carried out of the hospital staff), if doctors felt that no one was noticing their hygiene, they tended to hand wash with much less care - less than half efficiency, to be exact. To get these results, the researchers infiltrated a group of 17 people in the hospital: two of them were nurses, known by the local team, the other 15 were young doctors had never seen - were plainclothes agents of the study. The outcome was impressive: when they met the unknown, doctors met, on average, only 22% of the recommended health protocol; see the infiltrated nurses, on the other hand, the rate rose to 57% - but still stays low.
Sampling to arrive in numbers was not small. The researchers caught him 4,640 scenes between July and December 2015. And to ensure that unknown infiltrators had the ability to judge the cleaning - even without being professionals - they had a crash course on the hand hygiene protocol in a hospital.
The data surprised the hospital board, who believed in less interference monitoring the results. The bad numbers, on the other hand, left a promise: this will help to improve the quality of the property. "We made several changes in order to achieve the organization. Among them is a new plan for hand hygiene," said Nancy Johnson hospital infection prevention manager. The shape of hygiene inspections will also change. "After the results, we will begin to anonymously monitor the hygiene of employees," he adds.
The change in behavior caused by the observation of third parties is not new to science. In fact, it is studied since 1924 and even has a fancy name: Hawthorne effect - which got its name because the first place where there was the detection of this phenomenon was the American electrical company called Hawthorne Works. Now, the idea of using this type of technique in medicine animates experts. "The study showed that our hands hygiene is influenced by Hawthorne and the use of unknown observers should be used to reach more accurate data," said Maricris Niles, preventions analyst hospital infections. The next time you stop in an emergency room and run into a doctor in the bathroom, it is seen in the hands - he may find that you're undercover.
Failure to correct sanitizing medical hands increases the chances of nosocomial infections - these account for about 100,000 deaths annually in Brazil. It is estimated that Brazilian doctors wash their hands half the necessary situations.
