Targeting MRSA: Is it the right infection prevention goal?
GENERAL PURPOSE: To provide information about the variety of approaches to managing HAIs related to MRSA. LEARNING OBJECTIVES: After reading the article and taking this test, you'll be able to: 1. Describe the history of MRSA infection. 2. Discuss approaches to controlling HAIs related to MRSA.
- In the 1950s and 1960s,
- MRSA was identified as a community-acquired pathogen.
- S. aureus was established as a healthcare-associated pathogen in North America.
- MRSA infections rose to epidemic proportions.
- S. aureus was identified as a healthcare-associated pathogen worldwide.
- MRSA was first identified in
- Methicillin was approved for treatment ofaureus in
- The MRSA epidemic of the late 1990s and early 2000s was characterized by
- sicker inpatients becoming infected.
- an increase in healthcare transmission.
- transmission by healthcare employees.
- the appearance of community-associated MRSA.
- The USA300 strain of MRSA
- developed independently in the community.
- escaped from hospitals into the community.
- was started by patients infected in the hospital.
- was primarily associated with transmission by healthcare workers.
- Contact precautions for MRSA
- were accepted by a broad consensus as necessary to control the spread of infection.
- don't seem to prevent the spread of the organism.
- were heatedly contested.
- have been shown to prevent the spread of HAIs into the community.
- Regarding contact precautions for MRSA, the CDC guidelines
- support their use.
- question their use.
- recommend more research on their efficacy.
- deny their value.
- One problem associated with the use of contact precautions is that
- families object to the procedures required to visit their loved ones.
- physicians refuse to change their PPE between patient visits.
- healthcare professionals, including physicians, are half as likely to enter the patient's room.
- families report increased anxiety and depression when their loved ones are in isolation.
- Studies have demonstrated additional problems with contact isolation, including
- restrictive visiting hours.
- the inability to document care effectively.
- reuse of PPE to save money.
- higher patient acquisition rates of other MDROs.
- To reduce the cost of PPE, some institutions
- only require gowns for the sickest patients.
- only require gowns when patient contact is anticipated.
- leave a gown in a patient's room for reuse.
- strictly limit the number of visits to each patient per day.
- AST is the screening of
- patients for MRSA on admission.
- patients suspected to be infected or colonized with MRSA.
- individuals in the community who are suspected to be infected with MRSA.
- families of patients who are infected or colonized with MRSA.
- In 2003, which organization issued guidelines recommending AST for MRSA?
- Centers for Medicare and Medicaid Services
- Association for Professionals in Infection Control and Epidemiology
- In a 2008 SHEA article, the authors noted that focusing on MRSA
- increased the effectiveness of infection prevention protocols.
- enhanced the researchers' abilities to develop targeted approaches to prevention and treatment.
- brought national attention to the severity and threat of MRSA.
- prevented fewer infections than broader approaches to infection prevention.
- Recent data demonstrate that
- MRSA is the most common healthcare-associated pathogen.
- MRSA infections are declining.
- practicing hand hygiene effectively eliminates MRSA.
- community-associated MRSA is more prevalent now than hospital-acquired MRSA.
- Which arm of the REDUCE MRSA Trial demonstrated the greatest reduction in ICU-attributed CLABSIs?
- AST followed by contact precautions for MRSA-positive patients.
- AST followed by mupirocin and CHG baths for MRSA-positive patients.
- No AST; every patient was decolonized and bathed daily with CHG.
- No AST; every patient was decolonized and their hand hygiene practices were monitored.
- Best practice for infection prevention should include
- a push toward targeting the most prevalent infectious agents.
- a universal infection control approach that targets all HAIs.
- emphasizing hand hygiene above all other infection prevention measures.
- eliminating MRSA, the most hazardous of all current HAIs.
