Uniforms of hospital nurses and doctors contain potentially dangerous bacteria majority of the time, says a new research.
The team led by Yonit Wiener-Well, MD from the Shaare Zedek Medical Center in Jerusalem, Israel found that more than 60 percent of hospital nurses' and doctors' uniforms tested positive for potentially dangerous bacteria.
AdvertisementFor the study, researchers collected swab samples from three parts of the uniforms of 75 registered nurses (RNs) and 60 medical doctors (MDs) by pressing standard blood agar plates at the abdominal zone, sleeves' ends and pockets.
The researchers at this 550-bed, university-affiliated hospital found that exactly half of all the cultures taken, representing 65 percent of the RN uniforms and 60 percent of the MD uniforms, harboured pathogens.
Of those, 21 cultures from RN uniforms and six cultures from MD uniforms contained multi-drug resistant pathogens, including eight cultures that grew methicillin-resistant Staphylococcus aureus (MRSA).
Although the uniforms themselves may not pose a direct risk of disease transmission, these results indicate a prevalence of antibiotic resistant strains in close proximity to hospitalised patients.
"It is important to put these study results into perspective," Russell Olmsted, 2011 APIC President, said.
"Any clothing that is worn by humans will become contaminated with micro organisms. The cornerstone of infection prevention remains the use of hand hygiene to prevent the movement of microbes from these surfaces to patients.
"New evidence such as this study by Dr. Wiener-Well is helpful to improve the understanding of potential sources of contamination but, as is true for many studies, it raises additional questions that need to be investigated," Olmsted stated.
The study has been published in the September issue of the American Journal of Infection Control, the official publication of the Association for Professionals in Infection Control and Epidemology (APIC).
