Methicillin-resistant Staphylococcus aureus in hospitals: time for a culture change

To the Editor: The recent editorial by Collignon and colleagues emphasised the importance of infection control mechanisms in reducing patient harm from antibiotic-resistant organisms.1 It focused on disinfection of the hands of health care workers in hospitals. However, a vigorous education and surveillance program in a hospital in Victoria failed to achieve compliance among health care workers of even 50%.2 Top of the list of self-reported factors leading to poor compliance is “skin irritation and dryness associated with the use of hand hygiene agents”.3

There have been no properly controlled trials, with clinically important endpoints, of currently recommended hand-hygiene practices. With the likely poor compliance rates, such trials would likely fail.

A different approach might be more effective. Reducing skin contact between health care workers, patients and their immediate environment seems logical. Data show that skin contact produces two-step transfer of material in 82% of cases.4 The Victorian study did include gloving as an alternative to disinfection in measuring hand-hygiene compliance.2 However, in what might be a backward step, a recent study concluded that physicians should be encouraged to shake hands with patients!5

Perhaps an educational campaign to avoid skin contact with environmental surfaces and other health care workers, with use of disposable gloves for patient contact, could be the basis of a successful trial to address more effectively the transmission of antibiotic-resistant organisms in hospitals.
