Methicillin-resistant Staphylococcus aureus (MRSA)

How is the MRSA rate calculated?
The infection rate is calculated as a rate per 1,000 patient days. “Total number of patient days” represents the sum of the number of days during which services were provided to all inpatients during the given time period.

The rate is calculated as follows: 

Number of nosocomial patients with laboratory identification
       of MRSA bacteraemia  x 1000     
Total number of patient days

Frequently Asked Questions

What is Methicillin-resistant Staphylococcus aureus (MRSA)?MRSA is a bacterium, Staphylococcus aureus, that has developed a resistance to the antibiotics commonly prescribed to kill it. The bacterium is commonly found on the skin and mucus membranes and can cause an infection. MRSA can be found in the nose or rectum of patients
Who is at risk for MRSA? People who have weak immune systems or are on antibiotics are at risk of getting MRSA. Patients who have been in the hospital for a long time or have had many medical procedures also have an increased risk of contracting MRSA
How do you get MRSA?MRSA is spread from one person to another, usually by caregivers, through physical contact or by touching contaminated material discharged by an infected person. MRSA is found on the hands of caregivers or on articles contaminated by the skin of a person with MRSA such as towels and sheets.
How is MRSA treated? Treatment depends on how sick you are. People with mild symptoms may not need treatment. For more severe cases, antibiotics are required.
How is the spread of MRSA prevented in the hospital? The spread of MRSA occurs due to inadequate hand hygiene and environmental cleaning; therefore, proper control is achieved through consistent hand hygiene and thorough cleaning of the patient environment. Good hand hygiene (i.e. washing hands thoroughly and often) is the single-most effective way to prevent the spread of infectious diseases like MRSA. If you are infected with MRSA you may expect the following precautions to take place during your stay at the hospital to prevent the spread of infection to other patients.
  • You may be moved to a single room
  • Everyone entering your room will wear a gown, gloves and a mask
  • Everyone who leaves your room should remove all protective wear and wash their hands
  • You must clean your hands before you leave your room and only leave your room when you have permission to do so.

What is Markham Stouffville Hospital doing to prevent the spread of MRSA? Markham Stouffville Hospital has implemented the Ministry of Health and Long Term Care’s Just Clean Your Hands hand hygiene initiative. We are working with employees, visitors and patients to minimize hospital-acquired infections through:
  • Hand cleaning initiatives
  • Environmental cleaning
  • Sterilization of equipment
  • Education Additional isolation precautions
