SHEA: Obsessed, and proudly so
Therein lies the rub with HCP attire, as with so many other infection prevention practices. There may be biological plausibility that clothing plays a role in pathogen transmission, there may be evidence for pathogen contamination of HCP attire, and there may be a favorable balance of benefit versus harm in implementing changes in practice (such as a bare-below-the-elbows (BBE) approach). But we still lack that direct link between HCP attire and HAI risk. Thus the SHEA guidance ends with a laundry list (pun intended) of research priorities for HCP attire:
· Determine the role played by healthcare personnel (HCP) attire in the horizontal transmission of nosocomial pathogens and its impact on the burden of HAIs.Now try to imagine the logistics, and costs, associated with a study large enough to demonstrate the incremental contribution of HCP attire to HAI infection risk, or the impact of BBE on HAI incidence. Knowing how long we will be waiting for such evidence, what do you plan to do in your hospital?
· Evaluate the impact of antimicrobial fabrics on the bacterial burden of HCP attire, horizontal transmission of pathogens, and HAIs. Concomitantly, a cost-benefit analysis should be conducted to determine the financial merit of this approach.
· Establish the effect of a bare-below-the-elbows (BBE) policy on both the horizontal transmission of nosocomial pathogens and the incidence of HAIs.
· Explore the behavioral determinants of laundering practices among HCP regarding different apparel and examine potential interventions to decrease barriers and improve compliance with laundering.
· Examine the impact of not wearing white coats on patients’ and colleagues’ perceptions of professionalism on the basis of HCP variables (e.g., gender, age).
· Evaluate the impact of compliance with hand hygiene and standard precautions on contamination of HCP apparel.
