“…21 Similarly, HCP clothing contaminated with S. aureus, Acinetobacter spp., and/or enterococci is associated with increased risk of contaminated HCP hands. 22 Indeed, HCP clothing can become contaminated by interacting with either patients or the environment. 23 Patients regularly contaminate their environment, 24,25 which may be the biggest predictor of HCP contamination.…”

objective. To determine whether antimicrobial-impregnated textiles decrease the acquisition of pathogens by healthcare provider (HCP) clothing.design. We completed a 3-arm randomized controlled trial to test the efficacy of 2 types of antimicrobial-impregnated clothing compared to standard HCP clothing. Cultures were obtained from each nurse participant, the healthcare environment, and patients during each shift. The primary outcome was the change in total contamination on nurse scrubs, measured as the sum of colony-forming units (CFU) of bacteria.participants and setting. Nurses working in medical and surgical ICUs in a 936-bed tertiary-care hospital.intervention. Nurse subjects wore standard cotton-polyester surgical scrubs (control), scrubs that contained a complex element compound with a silver-alloy embedded in its fibers (Scrub 1), or scrubs impregnated with an organosilane-based quaternary ammonium and a hydrophobic fluoroacrylate copolymer emulsion (Scrub 2). Nurse participants were blinded to scrub type and randomly participated in all 3 arms during 3 consecutive 12-hour shifts in the intensive care unit.results. In total, 40 nurses were enrolled and completed 3 shifts. Analyses of 2,919 cultures from the environment and 2,185 from HCP clothing showed that scrub type was not associated with a change in HCP clothing contamination (P = .70). Mean difference estimates were 0.118 for the Scrub 1 arm (95% confidence interval [CI], −0.206 to 0.441; P = .48) and 0.009 for the Scrub 2 rm (95% CI, −0.323 to 0.342; P = .96) compared to the control. HCP became newly contaminated with important pathogens during 19 of the 120 shifts (16%).conclusions. Antimicrobial-impregnated scrubs were not effective at reducing HCP contamination. However, the environment is an important source of HCP clothing contamination. trial registration. Clinicaltrials.gov Identifier: NCT 02645214

The presence of microorganisms on these items has been well documented [Munoz-Price et al 2012;Singh et al 2002;Goldblatt et al 2007;Lopez et al 2009]. Recently, the Society for Healthcare Epidemiology of America issued new guidelines to reduce the use of white coats in the clinical setting [Bearman et al 2014].…”

The role of the environment in harboring and transmitting multidrug-resistant organisms has become clearer due to a series of publications linking environmental contamination with increased risk of hospital-associated infections. The incidence of antimicrobial resistance is also increasing, leading to higher morbidity and mortality associated with hospital-associated infections. The purpose of this review is to evaluate the evidence supporting the existing methods of environmental control of organisms: environmental disinfection, contact precautions, and hand hygiene. These methods have been routinely employed, but transmission of multidrug-resistant organisms continues to occur in healthcare facilities throughout the country and worldwide. Several new technologies have entered the healthcare market that have the potential to close this gap and enhance the containment of multidrugresistant organisms: improved chemical disinfection, environmental monitoring, molecular epidemiology, self-cleaning surfaces, and automated disinfection systems. A review of the existing literature regarding these interventions is provided. Overall, the role of the environment is still underestimated and new techniques may be required to mitigate the role that environmental transmission plays in acquisition of multidrug-resistant organisms.

“…The purpose of protective outerwear is to limit the transfer of pathogens between the wearer and the patient, and its importance in infection control is often underappreciated. [125][126][127] a. Laboratory coats, smocks, aprons, and coveralls Laboratory coats, smocks, aprons, and coveralls serve as a temporary layer of protection that prevents contamination of the wearer' s garments.…”
