Studies show: Infection numbers decrease significantly when using no touch dispensers


In times of health care associated infections (HAI) and the increasing problem of antimicrobial resistance (AMR) no touch hand washing systems get more important, Yusuke Saraya, president of Saraya Co., Ltd, is convinced.

Health care workers are very busy, and every measure that is simplifying their daily life in hospitals, is surely welcome. Are there any studies showing that the health hygiene compliance is increasing when implementing no touch hand washing systems? 

To promote hand hygiene in such busy situations as patient care, dispensers are utilized for improving hand hygiene compliance. There are several studies that support this. According to Dr. Bischoff of the Hanover Medical School, after the introduction of easily accessible hand rub with dispensers, the performed hand hygiene compliance rate was significantly improved1). In addition, there are studies, which show that no touch dispensers were used significantly more often than manual dispensers. According to a research paper which was done in a large pediatric hospital, no touch dispensers were used 4.42 times per hour while manual dispenser was 3.33 times per hour2). In another study by Professor Ojan Assadian of the University of Huddersfield, no touch dispensers were used more than double compared to manual, elbow or foot type dispensers. Although there is a positive effect with the use of no touch dispensers shown in these cases, the accumulation of more studies to develop evidence is still required3). No touch dispensers are attractive to users because of an aesthetic appeal and ease of use4). Users are drawn to them and often use without thinking about hand hygiene. This leads to high hand hygiene compliance, according to our customers’ response. Because of academic and user feedback, we will continue to improve our automatic dispenser technology to contribute further to safer care in healthcare settings.

And are there any figures that demonstrate a decreasing of healthcare associated infections (HAI) when using no touch hand washing systems? Could you give an example (Hospital XY, implementation, and the figures before and after).

Numerous studies have been published showing the enhancement of hand hygiene areas (sinks or alcohol hand rub dispenser areas) led to an increase in hand hygiene compliance and a reduction of Healthcare Associated Infections (HAI). One study by Professor Didier Pittet5) showed a reduction in nosocomial infection from 16.9% in 1994 to 9.9% in 1998. No touch dispensers may be one advantage in enhancing hand hygiene areas.
We know the reasons why many hospitals choose to install our no touch dispensers; however we are not always sure about the actual HAI rates. A hospital will adopt no touch dispensers to reduce the cross contamination from touching pumps with the hands. The hygienic design and automatic convenience when accepted by healthcare workers seems to lend in developing further interest in hand hygiene. So far, it seems that hand hygiene compliance rates increase according to those in charge of Infection Control.
Since there is possibility of cross-contamination through manual dispensers such as bacterial spores4), no touch dispensers would be safer than manual dispensers for the purpose of the reduction of healthcare associated infections.

And what are the characteristics of the Saraya no touch hand washing system? In which way does it differ from other systems?

According to our users, reliability is one of our defining features. For example, our GUD-1000 dispenser has a longer battery life of more than 1 year compared to other products which average 6 months or less. In addition, a variety of designs and safer management with lockable key system are also our advantages.
A reliable amount of dispense of hand rub is also important for users who want to ensure their hands are fully covered to complete the whole hand disinfecting process. For instance, the GUD-1000 always dispenses an accurate, prescribed amount from the pump no matter what type of liquid, spray, gel or foam it is. Therefore, users can be assured their hands will have a proper amount no matter where they clean their hands.

Semmelweis was initiated 2012 in Vienna/Austria by a group of engaged private people and meanwhile operates across the borders to address relevant health care topics in the EU. The Foundation is named after the famous Hungarian physician Dr. Ignaz Semmelweis, who suggested a lack of hygiene of doctors and staff to be the main reason for childbed fever. He tried to introduce hygiene protocols and with his famous study of 1847/48 he is seen as the father of evidence-based medicine.
