As of December 30, 2008, all hospitals are required to publicly report their Methicillin-resistant Staphylococcus aureus bloodstream infection rates on a quarterly basis. 

Staphylococcus aureus is a bacteria that lives on the skin and mucous membranes of healthy people.  Occasionally S. aureus can cause an infection. When S. aureus develops resistance to certain antibiotics, it is called methicillin-resistant Staphylococcus aureus, or MRSA.

The method for calculating the MRSA bacteraemia rate is as follows:

 Number of nosocomial patients with laboratory identification of MRSA bacteraemia x 1000

Total number of patient days

OSMH cases of MRSA bloodstream infection are presented below:

Rates for the province of Ontario can be found at MOHLTC Patient Safety
