What is the impact of having an invasive medical device in relation to HA-MRSA risk?

• A. Increases risk of infection
• B. No impact on infection risk
• C. Decreases risk of transition
• D. Only affects certain populations

Answer: (A)

Having an invasive medical device significantly increases the risk of HA-MRSA infection. Invasive devices, such as catheters, ventilators, and surgical implants, create a direct pathway for bacteria to enter the body, bypassing the skin's natural defenses. This environment not only facilitates the entry of MRSA but can also provide a surface for the bacteria to adhere and form biofilms, which are particularly resistant to both the immune response and antibiotic treatment. The placement and maintenance of these devices are critical times where contamination can occur, and healthcare-associated infections, including those caused by methicillin-resistant Staphylococcus aureus (MRSA), are often directly linked to these devices. Therefore, understanding the relationship between invasive devices and infection risk is essential for infection control practices in healthcare settings. Effective strategies then include maintaining strict hygiene protocols and monitoring for signs of infection in patients with such devices.
