For example, incidence of caused methicillin-resistant Staphylococcus aureus 0.61 patient-days 0.05 1996 ( p Conclusion: method applicable a wide variety hospitals, even those with little no experience surveillance. By method, defined epidemiology significantly rates while achieving substantial cost savings.
