Health care workers who wash their scrubs at home may be inadvertently spreading antibiotic-resistant infections in hospitals, according to new research published in PLOS One. The study found that domestic washing machines are often insufficient for decontaminating health care worker uniforms.
Researchers recommend that hospitals launder scrubs on-site and update guidelines for health care workers on how to wash their uniforms at home. The study’s authors stated that domestic washing machines fail to disinfect textiles, allowing antibiotic-resistant bacteria to survive. This is a concern given the global health threat of antibiotic resistance, which is estimated to have led to over 1 million deaths per year between 1990 and 2021.
The researchers tested various washing machines on rapid and normal cycles to determine their effectiveness in decontaminating scrubs. The results showed that nearly half of the machines failed to disinfect clothing swatches on rapid cycles, while one-third did not sufficiently clean fabric on regular cycles. Furthermore, bacteria and antibiotic-resistance genes were found on swabs from inside the machines.
The study’s findings highlight the need for improved guidelines and infrastructure to prevent the spread of infection through domestic laundry. Hospitals and health care organizations must consider implementing on-site laundry facilities and providing guidance on proper washing techniques to reduce the risk of transmission of infectious disease via textiles.
