MRSA: why have we got it and can we do anything about it?

Area of Science:

• Infectious Diseases
• Public Health
• Healthcare Management

Background:

• Methicillin-resistant Staphylococcus aureus (MRSA) emerged as a significant healthcare-associated infection, with epidemic strains causing concern.
• MRSA bacteraemia peaked in England in 2003-2004, necessitating urgent public health interventions.

Purpose of the Study:

• To evaluate the impact of a national improvement program on MRSA bacteraemia rates.
• To identify key factors contributing to the reduction of healthcare-associated MRSA infections.

Main Methods:

• Implementation of a central improvement program focused on infection prevention and control.
• Enhanced surveillance of MRSA bacteraemia, alongside adherence to clinical protocols and care bundles.
• Focus on hand hygiene, environmental cleaning, isolation procedures, and antibiotic stewardship.

Main Results:

• MRSA bacteraemias reduced by 80% from a peak of 7700 to 1481 by 2011.
• Key drivers included management commitment, improved surveillance, protocol adherence, and antibiotic stewardship.
• Successful reduction demonstrates the effectiveness of a multi-faceted approach to infection control.

Conclusions:

• A collaborative approach involving clinicians, managers, and government is essential for controlling MRSA.
• Ongoing vigilance, screening programs, and sustained adherence to infection control policies are vital for maintaining reductions.
