The role of healthcare personnel (HCP) attire in cross-transmission of pathogens remains unclear. Guidance on HCP attire in non-operating room settings should attempt to balance professional appearance, comfort, and practicality with the potential risk that attire will contribute to the spread of nosocomial microbes. Institutions considering these optional measures should introduce them with a well-organized communication and education effort directed at both HCP and patients.
- There is a growing awareness of the potential role of fomites in the transmission of healthcare-associated microorganisms.
- Studies have demonstrated contamination of healthcare personnel attire (scrubs, white coats, ties) with potential pathogens, although the role of clothing in transmission of these microorganisms to patients has not been established.
- Most studies on patient attitudes toward HCP attire indicate that patients favor formal attire, including a white coat.
- Patients generally do not perceive white coats, formal attire, or neckties as posing infection risks; however, when informed of potential risks associated with certain types of attire, patients are willing to change their preferences for physician attire.
- No clinical studies have demonstrated cross-transmission of healthcare-associated pathogens from a HCP to a patient via apparel. A number of small prospective trials have documented contamination of HCP apparel with a variety of pathogens. These findings raise a hypothetical concern for pathogen cross-transmission to patients.
- Nametags have been identified consistently by patients as an important component of HCP attire.
- The United Kingdom (U.K.) has adopted a BBE approach (“bare below the elbows”—wearing of short sleeves and no wristwatch, jewelry, or ties during clinical practice), based on the theory that the strategy will limit patient contact with contaminated healthcare personnel attire and promote better hand and wrist hygiene.
- The impact of BBE on HCP bacterial counts remains poorly defined. One randomized trial comparing bacterial contamination of white coats against BBE found no difference in total bacterial or MRSA counts (on either the apparel itself or the volar surface of the wrist) at the end of an eight-hour workday.
- Uptake of BBE in healthcare settings has been variable.
- To date there is no definitive evidence that a BBE approach to inpatient care results in improved hospital-acquired infection (HAI) outcomes.
- The optimal frequency for laundering apparel is not clear based on the current literature. Apparel worn at the bedside that comes in contact with the patient or patient environment should ideally be laundered after daily use.
- Whether HCP attire for non-surgical settings should be laundered at home or professionally remains uncertain. A combination of washing at higher temperatures and tumble drying or ironing has been associated with elimination of both pathogenic Gram-positive and Gram-negative bacteria from HCP clothing.
- Although the choice of healthcare personnel attire may affect infection rates, evidence-based measures to prevent HAIs (e.g., hand hygiene, appropriate device insertion and care, isolation of patients with communicable diseases, environmental disinfection) should take priority.
- Facilities may consider adoption of a BBE approach to inpatient care as an infection prevention adjunct. There are no data to guide the optimal choice of alternate attire, such as scrub uniforms or other short-sleeved personal attire. This approach is supported by biological plausibility and is unlikely to cause harm.
- In facilities wherewhite coats are used for professional appearance, commonsense measures should be considered. HCP engaged in direct patient care should possess two or more white coats and have access to a convenient and economical means to launder white coats. Also, institutions should provide coat hooks that would allow HCP to remove their white coat (or other long-sleeved outerwear) prior to contact with patients or patients’ immediate environment.
- Neckties should be secured to prevent them from coming into direct contact with patients or patients’ immediate environment.
- Any apparel worn at the bedside that comes in contact with patients or patients’ environment should be laundered after daily use.
- If laundered at home, apparel should be washed in a hot water wash cycle followed by a cycle in the dryer.
- All HCP footwear should have closed toes, low heels, and non-skid soles.
SUGGESTED PRACTICE IN UNDER-RESOURCED SETTINGS
The practices listed above are equally applicable to under-resourced settings.
- The role of healthcare personnel attire in cross-transmission of nosocomial pathogens has not been established. HCP attire frequently becomes contaminated with bacteria during the course of clinical care. This includes scrubs, neckties, and white coats, with pathogens such as Staphylococcus aureus, methicillin-resistant Staphylococcus aureus(MRSA), vancomycin-resistant enterococci (VRE), and Gram-negative bacilli. The impact of apparel microbial burden on occurrence of HAI is undefined. Although patients frequently express preferences for certain types of HCP attire, including white coats, they were willing to change their preferences when informed of potential risks associated with HCP attire. Patient comfort, satisfaction, trust, and confidence in their physicians is unlikely to be affected by practitioners’ attire choice, with the exception of name tags, which they viewed as essential.
- A BBE approach is in effect in the U.K. for inpatient care; this strategy may enhance hand hygiene to the level of the wrist, but its impact on HAI rates remains unknown. Facilities may consider adoption of a BBE approach to inpatient care as an adjunctive infection prevention measure. The optimal choice of alternate attire, such as scrub uniforms, remains unknown. This strategy is supported by biological plausibility and is unlikely to cause harm. In facilities wherewhite coats are used for professional appearance, HCP engaged in direct patient care should possess two or more white coats and have access to a convenient means of laundering the white coats. The benefit of institutional laundering of HCP scrubs versus home laundering for non-OR use remains unproven. Institutions should provide coat hooks that would allow HCP to remove their white coat (or other long-sleeved outerwear) prior to contact with patients or the patient’s immediate environment.
- Ties should be fastened so as to not come into direct contact with the patient or immediate patient care environment. Shoes should have closed toes, low heels, and non-skid soles. Nametags should be used and easily visible.
