MRSA Bacteraemia Infection Rates Reporting
Public reporting of new Methicillin-resistant Staphylococcus aureus bacteraemia infection rates in Ontario hospitals began on December 30, 2008.
Hospitals will post their rates and case counts of new MRSA bacteraemia acquired in their facility on their website every three months (quarterly), and
will also report their data to the Ministry of Health and Long-Term Care through an online template captured by a central database.
What is bacteraemia?
Bacteraemia is the presence of bacteria in the blood stream and is referred to as a bloodstream infection.
What is Methicillin-resistant Staphylococcus aureus?
Staphylococcus aureus is a bacteria that can live on the skin and mucous membranes of healthy people. Occasionally, S. aureus can cause an infection.
When S. aureus develops a resistance to certain antibiotics, it is called methicillin-resistant Staphylococcus aureus, or MRSA.
What will be publicly reported?
Each hospital will post its quarterly rate and case count of new MRSA bacteraemia acquired in their facility on their website. As well, at the end of each
quarter, the ministry will report the previous quarter’s data on its website by hospital site including:
1. The number of new hospital acquired MRSA bacteraemia cases that is zero (0) or totalling five (5) or more associated with that hospital site, or if this is less than 5 cases (i.e. 1 to 4 cases), text reading “<5cases”, and
2. The hospital acquired MRSA bacteraemia rate
What determines the rate?
The total number of new cases of MRSA bacteraemia acquired in the hospital in a quarter is divided by the total number of patient days for that
quarter. Patient days are the number of days spent in the hospital for all patients. The results are multiplied by 1000. This represents the rate of
hospital acquired associated MRSA bacteraemia associated with the reporting facility per 1000 patient days for that quarter. (e.g. 2 cases for that
quarter divided by 30,000 patient days for that
quarter = 0.00006 x 1000 = 0.06 per 1000 patient days). The rates of infection will be calculated by quarter.
What is the rate at TDMH?
The TDMH rate for the quarter April 1 to June 30, 2024 is 0 per 1000 patient days. This represents 0 cases.
The TDMH rate for the quarter January 1 to March 31, 2024 is 0 per 1000 patient days. This represents 0 cases.
The TDMH rate for the quarter October 1 to December 31, 2023 is 0 per 1000 patient days. This represents 0 cases.
The TDMH rate for the quarter July 1 to September 30, 2023 is 0 per 1000 patient days. This represents 0 cases.
The TDMH rate for the quarter April 1 to June 30, 2023 is 0 per 1000 patient days. This represents 0 cases.
The TDMH rate for the quarter January 1 – March 31, 2023 is 0 per 1000 patient days. This represents 0 cases.
The TDMH rate for the quarter October 1 – December 31, 2022 is 0 per 1000 patient days. This represents 0 cases.
The TDMH rate for the quarter July 1 – September 30, 2022 is 0 per 1000 patient days. This represents 0 cases.
