MRSA (Methicillin Resistant Staphylococcus aureus) Bacteremia:  Rate per 1000 patient days

What does hospital-acquired mean?

Sometimes when patients are admitted to the hospital, they can get infections. This is a hospital-acquired infection. In the case of MRSA, this may mean that symptoms begin 72 hours after admission to the hospital. 

What is Methicillin-resistant Staphylococcus aureus (MRSA)?

Methicillin-resistant Staphylococcus aureus (MRSA) is a type of bacteria that is resistant to certain or all types of antibiotics such as penicillins, penicillinase-resistant penicillins (e.g. cloxacillin) and cephalosporins.

What are the risk factors for MRSA?

Risk factors for MRSA acquisition include invasive procedures, prior treatment with antibiotics, prolonged hospital stay, stay in an intensive care or burn unit, surgical wound infection and close proximity to a colonized person. MRSA can also be transmitted from mother to child through breast milk.




   How How is MRSA transmitted?

The single most important mode of transmission of MRSA in a health care setting is via transiently colonized hands of health care workers who acquire it from contact with colonized or infected patients, or after handling contaminated material or equipment. The unrecognized colonized patient presents a particular risk for transmission to other patients.

What are we doing to reduce infections at Hamilton Health Sciences?

HHS has several infection control improvement initiatives underway, including:

  • Reducing Ventilator Associated Pneumonia 

  • Reducing Surgical Site Infections 

  • Reducing Central Line Infections  

  • Improving Staff and Visitor Hand Hygiene practices (Hand Washing) 

  • Reducing Skin Breakdown
