In a recent study, researchers found that without timely intervention, privacy curtains in hospitals can become breeding grounds for resistant bacteria and pose a threat to patient safety.
The study tracked the contamination rate of ten freshly laundered privacy curtains in the Regional Burns/Plastics Unit of the Health Services Center in Winnipeg, Canada.
The curtains had minimal contamination when they were first hung. But the curtains that were hung in patient rooms became increasingly contaminated over time.
And by day 14, 87.5% of the curtains tested positive for methicillin-resistant Staphylococcus aureus (MRSA), a pathogen linked to high morbidity and mortality.
In contrast, control curtains that were not placed in patient rooms stayed clean the entire 21 days.
None of the rooms where the curtains were placed were occupied by patients with MRSA.
Four curtains were placed in a four-bedroom; four were placed in two double rooms, and two controls were placed in areas without direct patient or caregiver contact.
The researchers took samples from areas where people hold curtains and found that the increasing contamination resulted from direct contact.
They suggest that those privacy curtains pose a high risk for cross-contamination because they are frequently touched but infrequently changed.
The high rate of contamination by the fourteenth day may represent an opportune time to intervene, either by cleaning or replacing the curtains.
By day 21, almost all curtains exceeded 2.5 CFU/cm, the requirement for food processing equipment cleanliness in some locations, such as the United Kingdom.
The team suggests that keeping the patient’s environment clean is a critical component in preventing healthcare-associated infections.
Because privacy curtains could be a mode of disease transmission, maintaining a schedule of regular cleaning offers another potential way to protect patients from harm while they are in our care.
The study authors acknowledge the small sample size of this pilot study and recommend additional research to understand the clinical consequences of contaminated curtains.
