Infection Control Guide 2005
New Developments in the Infection Control War
Small world networks
and
battles on the homefront
by Jeannie Akridge
Welcome to the HPN 2005 Annual Infection Control
Guide. More products are being developed that address the complexity of
infection control and safety for patients and healthcare staff. This
year we’ve compiled more companies and more product choices then ever.
We’ve also included an update on the importance of handwashing on page
46. As we all anticipate the spread of infection on a global basis - we
hope this guide helps you in your preparation defense. Our comprehensive
directory begins on page 48.
A message delivered a year ago in June, by the Centers
for Disease Control and Prevention’s director Julie L. Gerberding, MD,
MPH, foretold a year teeming with challenges, losses and victories in
the never-ending battle of infection control. Presenting the keynote
address at the annual meeting of the Association of Professionals in
Infection Control (APIC) in Phoenix, AZ, Gerberding spoke of the need to
recognize "small world networks" in which weak ties (people moving
between communities) become a link to connect highly clustered
communities. As examples, she cited the Hong Kong traveler who spread
SARS throughout the world, and the American Midwest pet shop where the
spread of monkeypox began. She then urged infection control
professionals to be a strong link for learning…to promote health,
prevent disease and improve preparedness to meet health challenges; to
serve as knowledge managers, early warning leaders, expert
spokespersons, global health ambassadors and patient advocates. She
introduced new health priorities for the CDC with a focus on prevention
and preparedness.
Over the next year, those in the healthcare profession
would have their strength and resolve tested against numerous and
unforeseen threats to global health. The WHO issued warnings that the
avian flu could mutate and cause an unprecedented worldwide pandemic;
and the U.S. faced a shortage of flu vaccine after a major manufacturer
found contaminated doses and was forced to stop production.
On the sterile processing front, several incidents of
improperly cleaned instruments put patients at risk of disease. Also in
2004, New Jersey became the first state to pass a mandatory CS
certification law; and the FDA ruled that several single use devices
were no longer safe to be reprocessed.
In December 2004, Health and Human Services Secretary
Tommy Thomspon resigned, but not before issuing stern warnings about the
threat of a global flu pandemic and the risk of a terrorist attack on
the nation’s food supply. Days later, the FDA announced new, stricter
food-tracking rules. Also in December, the Institute for Healthcare
Improvement (IHI) announced its groundbreaking "100,000 Lives Campaign".
The campaign aimed to enlist thousands of hospitals across the country,
at no charge, in a commitment to implement changes in care that have
been proven to prevent avoidable deaths. The response was overwhelmingly
positive.
Then, just before the new year rolled over – in an eerie
omen to the absolute need to be ever-vigilant – a killer tsunami washed
ashore in southeast Asia, causing fear of typhoid, hepatitis, and other
disease epidemics among shaken survivors and the world.
The first half of 2005 brought continued challenges with
MRSA, which shut down a Vancouver hospital and was reported as reaching
out into the community in record numbers. A rare and aggressive HIV was
reported in New York; an epidemic of Marburg hemorrhagic fever ravaged
Angola; and a killer virus was accidentally sent in lab samples
throughout the world.
In February 2005, a report showed that U.S. hospital
infections claimed more lives than AIDS, breast cancer and traffic
accidents combined and warned that before the end of the year, such
infections would claim over 100,000 lives and become the fourth largest
killer of Americans. The Committee to Reduce Infection Deaths urged
public pressure on hospitals to "clean up" by following basic hygiene
procedures and to "come clean" by publicly disclosing infection rates.
That same month, Maryland weighed a bill forcing data collection on
hospital-acquired infections, joining several other states in a move
toward mandatory infection reporting. The CDC stepped in in March,
issuing guidelines to hospitals for reporting on infections.
Seeming to make good on Gerberding’s promise for
heightened prevention and preparedness measures, in April 2005, the CDC
announced a major reorganization that created four new coordinating
centers designed to defend against a new breed of 21st century health
threats.
As 2005 rolls on, infection control professionals and
other healthcare workers need to continue to stand united against these
21st century health threats. Basic regimens such as proper hand washing
and disinfecting surfaces will be combined with cutting edge technology
to fight long-time enemies and emerging pathogens.

Washing hands and
disinfecting surfaces still a primary defense
It can never be stressed enough the importance a
simple act like hand washing can have on reducing the spread of
viruses and other pathogens.
According to a study published in the Journal of
Infection, it takes only one child coming home with the flu to
contaminate nearly 60 percent of common household surfaces1.
The study, conducted by researchers at The University of Arizona,
Tucson, and funded by Clorox, evaluated the prevalence of the
influenza A virus on surfaces in day care centers and homes with
sick children to assess the potential role surfaces have in
transmitting the flu virus. They found the flu virus on 59 percent
of surfaces in homes that were sampled during March 2003 and 53
percent of surfaces in day care centers tested during the Spring.
Viruses were found to be infective on hard surfaces for up to 48
hours and on wet surfaces for up to 72 hours.
Translate those numbers to the hospital environment
and the risk of infection through transference from hands to
surfaces and vice versa, is alarming.
The study noted that cleaning surfaces with
disinfecting products can help reduce the possibility of viral
transfer, transmission and possible infection.
"Washing hands and disinfecting surfaces is the
biggest way to stop the spread", emphasized one of the study’s lead
authors, Stephanie A. Boone, PhD. She stressed the need to wash
hands both before and after contact with infected patients, and to
frequently clean surfaces with a disinfectant, versus a sanitizer.
In a separate study, alcohol gel hand wipes were
shown to be extremely effective at killing and removing germs2. In
clinical studies, Sani Dex ALC Wipes from Professional Disposables
International were shown to remove soil and kill 99.99% of harmful
bacteria because of the natural friction caused by the wiping
action. Additionally the alcohol gel hand wipe achieved a higher
log10 reduction than the rub in alcohol hand gels. The study results
suggested that the superior performance of the wipe was augmented by
the physical removal of soil and bacteria.
Northridge Hospital Medical Center in California
uses Sani Dex hand wipes to prevent cross-contamination from pets to
humans in their pet therapy program. All staff, patients, volunteers
and visitors are required to use the wipes before and after petting
or handling the dogs.
Dr. Boone agreed that using a wipe does hold
distinct cross-contamination benefits. "You’re wiping the virus off
into the hand wipe and then you can toss it," she explained.
Wipes are also available to disinfect surfaces.
Clorox makes Disinfecting Wipes that are safe to use on most hard,
non-porous surfaces. Likewise, STERIS recently introduced its new
Germicidal Surface Wipes product, a non-woven disposable cloth
containing a stable, low pH formulated disinfectant and deodorant
designed for use on hard, non-porous surfaces such as stainless
steel, Formica, tables, carts, baskets, counters, cabinets and
telephones. The STERIS wipes can be used throughout the hospital
where control of cross-contamination is required. The product
provides broad spectrum biocidal activity, including M. tuberculosis
(TB) and HIV-1 (AIDS virus).
Continued warnings that the avian flu could mutate
into a human form underscores the need to practice primary infection
control measures such as hand washing. The University of Arizona
study noted "Vaccine and antiviral drug usage are not enough to
counter future pandemics or widespread outbreaks of influenza."1, 3
"The problem is that when a virus jumps species like
the SARS virus, you have severe repercussions in humans," said Dr.
Boone. Several factors influence a virus’ ability to spread out of
control, she said. 1) Despite best efforts at vaccination; not
everyone receives the vaccine. 2) It’s difficult to predict which
virus to include in the vaccine. 3) It takes six to nine months to
develop a new vaccine, which may not be quick enough to stop a
widespread outbreak.
"In the event that there is a mutation and the
transfer rate increases rapidly, you could suddenly have a pandemic
on your hands," warned Dr. Boone.
