Hospital floors create a route to transfer potentially dangerous organisms to patients

According to a study published today as part of the October 2020 minutes, hospital beds were quickly and frequently contaminated with antibiotic-resistant bacteria within hours of patient admission, resulting in potentially dangerous microorganisms. Create a route to the patient. International conference on medical-related infectious diseases.

Decennial 2020, an initiative of the Centers for Disease Control and Prevention and the American Association of Medical Epidemiology, was canceled in March due to a pandemic. All abstracts accepted at the conference are published as a supplement to the journal. Infection control and hospital epidemiology..

If the bacteria stay on the floor, this is not a problem, but despite current management efforts, there is clear evidence that these microorganisms are infecting the patient. Hand hygiene is important, but a pathogen to protect underestimated patients. “

Researchers at the Northeast Ohio VA Healthcare System closely tracked room contamination in 17 newly admitted patients and identified the timing and pathways of bacterial migration within the room. Prior to the test, the room was thoroughly cleaned and disinfected, and all patients were screened negative for methicillin-resistant Staphylococcus aureus (MRSA) and other medical-related bacteria.

Researchers then observe the interaction of the patient with the healthcare professional and mobile device and culture from the patient, socks, beds, other high-contact surfaces, and major parts of the floor 1-3 times daily. Collected.

Almost half of the rooms were MRSA positive within the first 24 hours, MRSA, C. Difficile and vancomycin-resistant enterococcal (VRE) pathogens were identified in 58% of rooms within 4 days of admission. Contamination often started on the floor, but eventually moved to the patient’s socks, bedding, and nearby surfaces.

Sarah Redmond, lead author and medical student at Case Western Reserve University, said: “Although these horrific sound bugs indicate that they can invade the room or its vicinity, not everyone who encounters the pathogen is infected. School of Medicine.” With that in mind, Is there an easy way to deal with these exposed areas without too much emphasis on risk? “

In a related study published in August Infection control and hospital epidemiology, The authors reported similar findings that SARS-CoV-2 nucleic acid was frequently detected on the floor and staff shoes of the COVID-19 ward.

The authors state that further research is needed to clarify the role of floor contamination in the transmission of both bacterial and viral pathogens and to identify practical approaches to combat contamination. .. In the COVID-19 ward, contamination was reduced by simply changing the floor cleaning and disinfection protocol.

Researchers have limited the study to some limitations, including small sample size and characteristic variables between patients and healthcare professionals, which can affect how the results of the study can be generalized to other hospitals. I paid attention.

The Decenial is held once every 10 years to review progress over the last decade and opportunities and trends in the areas of medical epidemiology, infectious diseases, infection prevention, and future antibiotic management. Decennial 2020, scheduled for March 26-30, 2020, was co-sponsored by the Society for Healthcare Epidemiology of America (SHEA) and the Centers for Disease Control and Prevention (CDC).
