在IDN的推特上，我发现了这篇报道。 这篇报道对研究结果进行了适当的描述，也将这个文章贴出，并将结果和方法标出。 HCW uniforms laundered in domestic setting eliminated bacteriaLakdawala N. Infect Control Hosp Epidemiol. 2011 [published online ahead of print Oct. 3].在这里可以看到，文章尚未发表，所以全文没有链接。
Methicillin-resistant Staphylococcus aureus and Acinetobacter baumannii were eliminated from health care workers’ uniforms when washed with detergent and water temperature of 40°C, followed by 7-seconds of exposure to a hot iron, or washing in 60°C, according to new findings published in Infection Control and Hospital Epidemiology.
“The results stress the importance of ironing hospital uniforms after washing them in a domestic washing machine that operates at less than 60°C,” John Holton, PhD, FRCPath, of the University of Middlesex in London, said in a press release. “We showed that laundry and ironing in a domestic setting is effective in producing a uniform free of accumulated hospital bacteria safe to wear to work.”
In four related studies, the researchers assessed the bioburden on uniforms before and after laundry, the varying times and temperatures during the laundry process and the effectiveness of low-temperature wash cycles and ironing on removal of methicillin-resistant Staphylococcus aureus (MRSA) and Acinetobacter baumannii.
At 40°C (the temperature at which domestic washing machines normally operate) MRSA was eliminated通过40°的清洗，可以清楚MRSA，但是却不能清楚AB, but Acinetobacter was still present. Yet, the researchers found that 7-seconds of exposure to a hot domestic iron eradicated Acinetobacter. 通过7秒的熨烫，可以清楚AB
“As lower temperatures and lower water use is likely to increase, particular attention should be paid to the organisms colonizing washing machines after laundering hospital uniforms,” the researchers wrote.
研究者也评价道，现在低温清洗和少量用水清洗HCW的白大褂，但是一些必要的条件还是要满足才能够完全清楚MRSA和AB。
注意，这里没有外延，因为只是用了两种指示菌。对MDRO而言，其对环境的抗力均不一致，所以不宜外推。
