About This Quiz

Health care-associated infection rates at USC University Hospital are higher than the national average. Poor hand hygiene is considered the leading cause of health care-associated infections, contributes to the spread of multi-resistant organisms, and is recognized as a significant contributor to infection outbreaks. Completion of this brief on-line CME activity will be recorded in your USC University Hospital medical staff records, and you will receive 1 unit of AMA category 1 CME credit. Objectives: At the completion of this activity, participants should be able to: •List indications for hand hygiene in the clinical setting. List risk factors for poor hand hygiene. Describe hand hygiene rates and effect on hospital infections. Improve hand hygiene performance in clinical settings. There is no industry support for this CME activity.

    Improved hand hygiene in recent hospital studies was associated with which of the following?

    • A reduction of catheter-related infections from 7.7 per 1000 catheter-days to 1.3 per 1000 catheter-days in 103 ICUs.2

    • A significant hospital-wide reduction (57%) in MRSA bacteraemia.3

    • A significant reduction (100%) of superficial surgical site infections (SSI) in neurosurgery; significantly lower SSI incidence in intervention ward compared with control ward.4

    • A significant reduction in health care-associated infections (HCAI) in adult ICUs (from 47.5/1000 patient-days to 27.9/1000 patient-days). 5

    • All are correct.

    Correct Answer
    A. All are correct.
    Explanation
    Hand hygiene is the primary measure proven to be effective in preventing health care-associated infections and the spread of antimicrobial resistance in hospitals and ICUs.1

  • 3. 

    Which one of the following is FALSE?

    • In a large Swiss university hospital, doctors cleansed their hands 57% of the times that they should have.1

    • In an Australian hospital hand washing campaign, mean compliance improved significantly from 21% at baseline to 48%.129

    • In the USC University hospital in 2009, doctors’ compliance with hand hygiene guidelines was 67%.

    Correct Answer
    A. In the USC University hospital in 2009, doctors’ compliance with hand hygiene guidelines was 67%.
    Explanation
    Option 3. is FALSE. In 2009 at USC University Hospitals, mean compliance with hand hygiene was only 55% (mean of monthly physician observation reports).8

    Please help reduce health care-associated infections in our hospital by improving your hand hygiene. We want all of our physicians to become good role models for the rest of the hospital staff. Thank you.
