MRSA distribution and epidemiological procedures evaluation at two hospitals in Northern Poland

In the present study we have analyzed the impact of modified MRSA screening of carriers and patients on epidemiological situation of MRSA during 2008–2010, comparing two regional hospitals with similar bed numbers and similar ward profiles in Northern Poland. In 2008 the proportion of MRSA to all S. aureus isolates was 14.4% resp. 6.0%, in 2009 8.3% resp. 4.7% and in 2010 6.5% in both hospitals. Independent of the different prevention and intervention strategy in both hospitals the different MRSA incidence seems to be due to regional epidemic settings.
