Hand Hygiene
Thank you to those who read my last posting about using disposable medical devices as an infection prevention method. I was interested to see the posting that you "try to clean stethoscopes between patients." There are numerous clinical studies that link proper disinfection of all medical devices to limiting the spread of a variety of infections.
Recently I attended the 19th Annual Scientific Meeting of the Society for Healthcare Epidemiology of America (SHEA) in San Diego. The updates at the meeting provided the latest information on new and emerging issues such as resistant gram negative bacteria, problematic outbreaks and cost-effective infection control, but I was most intrigued by continued concern around hand hygiene, and startling statistics about lack of compliance to basic handwashing practices.
Many factors have contributed to poor handwashing compliance among healthcare workers, including a lack of knowledge among personnel about the importance of hand hygiene in reducing the spread of infection and how hands become contaminated; lack of understanding of correct hand hygiene technique; understaffing and overcrowding; poor access to handwashing facilities; irritant contact dermatitis associated with frequent exposure to soap and water; and lack of institutional commitment to good hand hygiene.
Handwashing is one of the most fundamental practices we can take to prevent healthcare acquired infections yet the concern exists. Unless all factors that contribute to poor handwashing compliance are addressed, we will continue to see poor compliance with rates generally below 50% of hand hygiene opportunities.
The CDC's Healthcare Infection Control Practices Advisory Committee (HICPAC) published a comprehensive Guideline for Hand Hygiene in Health-Care Settings in 2002. One of the principal recommendations of this guideline was that waterless, alcohol-based hand rubs (liquids, gels or foams) are the preferred method for hand hygiene in most situations due to the superior efficacy of these agents in rapidly reducing bacterial counts on hands and their ease of use.
In addition, in the "How-to Guide: Improving Hand Hygiene
A Guide for Improving Practices among Health Care Workers, Institute for Healthcare Improvement, notes there are four components that are critical to a successful hand hygiene program.
1. Clinical staff, including new hires and trainees, understand key elements of hand hygiene practice (demonstrate knowledge)
2. Clinical staff, including new hires and trainees, use appropriate technique when cleansing their hands (demonstrate competence)
3. Alcohol-based hand rub and gloves are available at the point of care (enable staff) \
4. Hand hygiene is performed at the right time and in the right way and gloves are used appropriately as recommended by CDC's Standard Precautions (verify competency, monitor compliance, and provide feedback)
Some facilities have moved to surveillance methods to monitor handwashing practices in an effort to address this issue. Are any of you aware of surveillance policies in your facility? Have they worked for you? If so, can you share your experience?
