“…It has also been demonstrated that patients colonized or infected with VRE, C. difficile, and MRSA may shed these organisms during outpatient clinic visits and physical therapy appointments. 6,7,16,17 Cleaning and disinfection are challenging in outpatient clinics and in areas outside patient rooms. Multiple patients pass through areas each day with limited time for cleaning between patients.…”

Objective: To investigate the frequency of environmental contamination in hospital areas outside patient rooms and in outpatient healthcare facilities. Design: Culture survey. Setting: This study was conducted across 4 hospitals, 4 outpatient clinics, and 1 surgery center. Methods: We conducted 3 point-prevalence culture surveys for methicillin-resistant Staphylococcus aureus, vancomycin-resistant enterococci, Clostridioides difficile, Candida spp, and gram-negative bacilli including Enterobacteriaceae, Pseudomonas aeruginosa, Acinetobacter baumanii, and Stenotrophomonas maltophilia in each facility. In hospitals, high-touch surfaces were sampled from radiology, physical therapy, and mobile equipment and in emergency departments, waiting rooms, clinics, and endoscopy facilities. In outpatient facilities, surfaces were sampled in exam rooms including patient and provider areas, patient bathrooms, and waiting rooms and from portable equipment. Fluorescent markers were placed on high-touch surfaces and removal was assessed 1 day later. Results: In the hospitals, 110 (9.4%) of 1,195 sites were positive for 1 or more bacterial pathogens (range, 5.3%–13.7% for the 4 hospitals) and 70 (5.9%) were positive for Candida spp (range, 3.7%–5.9%). In outpatient facilities, 31 of 485 (6.4%) sites were positive for 1 or more bacterial pathogens (range, 2% to 14.4% for the 5 outpatient facilities) and 50 (10.3%) were positive for Candida spp (range, 3.9%–23.3%). Fluorescent markers had been removed from 33% of sites in hospitals (range, 28.4%–39.7%) and 46.3% of sites in outpatient clinics (range, 7.4%–82.8%). Conclusions: Surfaces in hospitals outside patient rooms and in outpatient facilities are frequently contaminated with healthcare-associated pathogens. Improvements in cleaning and disinfection practices are needed to reduce contamination.

“…However, the clothing and skin of patients are often contaminated with pathogens and may serve as a source for transfer to hands or surfaces. [6][7][8] Thus, it is not clear that the elbow bump is less likely to transfer pathogens than hand contact greetings. Here, we conducted a study with MRSA-colonized patients to test the hypothesis that the elbow bump transfers MRSA less frequently than the fist bump.…”
