Methicillin Resistant Staphylococcus Aureus (MRSA)
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 a 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 ÷ 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.
It is important to understand that differences among hospitals make it challenging to compare case counts and rates.
Several factors can affect hospital rates of MRSA Bacteraemia :
- the size of the institution
- the complexity of the services offered
- the type of patient population served
- the physical layout of the hospital
- the number of people hospitalized for respiratory infection
- the use of antibiotics
- the percentage of people above 65 in the hospital
Hospital rates can also fluctuate significantly from one reporting period to another for a variety of reasons. For example, a small hospital with relatively few patient days when compared to larger institutions could see its rates vary dramatically based on one or two cases in any given month. These types of fluctuations will level out over a longer period of time. The ministry will report MRSA trends when enough date becomes available.
The data presented on the ministry of health website is best used to measure individual hospital performance over time, rather than to compare hospitals to each other. It is best used as a tool for hospitals to monitor their infection prevention and control programs. It is not intended to be the only source of information for making decisions about hospital care, nor is it information for generalizing about the overall quality of care provided by hospitals.
