What's MRSA? Should you be worried?
Special to The Independent
10/26/2007
In recent weeks, the media has flooded us with reports of MRSA (methicillin-resistant
staphylococcus aureus) outbreaks and cases all over the country, including
deaths.
As often occurs, there is much misinformation being disseminated, causing
unnecessary alarm.
Summit Healthcare Regional Medical Center and its physicians want you to
know the facts about MRSA and how this infection could affect you and your
family.
The Journal of the American Medical Association published a study Oct. 17,
2007, which is the first study to look at MRSA nationwide in real time. The
study occurred between July 2004 and December 2005 in nine sites across the
country ranging from urban to rural cities and communities.
Staphyloccus aureus is a bacteria that we have known about for decades. The
bacteria may be acquired in three ways. The most common is called "community
onset" and occurs in people who have had medical exposure in the last 12
months, such as surgery, implantable device (like a pacemaker),
hospitalization and residence in a long-term care facility but are not
currently in the hospital.
MRSA may also be acquired during a current hospitalization and is often
called a nosocomial infection. MRSA may also be acquired in the community by
people with no risk factors.
Resistant strains have been a problem since the 1960s. In 2000, over half of
staph aureus cultured in intensive care unit patients was methicillin
resistant. In 1981, the first community associated (no risk factors) cases
were identified. Hospital acquired infections are generally harder to treat
than community acquired.
MRSA occurs in about 32 people per 100,000 per year. As with most
infections, there are risk factors. Certain groups are at higher risk to
both acquire the infection and to become sicker. People over the age of 65,
blacks and males are more prone to acquire MRSA. Children ages 5-17 are in
the lowest risk group.
Death is also associated with these same groups in a higher percent and is
more likely to occur if the disease is diagnosed later, when symptoms are
more severe (pneumonia, septic shock). In this regard, MRSA is very much
like most infectious diseases the medical profession encounters. MRSA is
susceptible to numerous antimicrobial agents, but many of these must be
initiated in the hospital setting.
There is only one basic recommendation to avoid MRSA infection that is
specific to this bacteria. Good hygiene and hand washing are the simplest
and the most frequently overlooked. The use of hand sanitizers are
effective. They can be carried as personal wipes or pocket solutions and are
available in dispensers throughout hospitals.
Avoid contact with people known to have MRSA infections. If a relative or
loved one is hospitalized with a MRSA infection, follow the hospital rules
regarding protection of both yourself and the patient, when visiting. Do not
visit if you have one of the risk factors above, or have recently been sick
or on antibiotics or are on chemotherapy that may suppress your immune
system.
Most importantly, if you have a skin or wound infection that seems to be
getting worse or spreading, see your healthcare provider immediately. Be
assured that when you have an infection that is cultured, MRSA is
automatically included. It does not have to be ordered specifically.
Additionally, Summit's Infection Control Department has kept a log of every
positive MRSA culture in the hospital since 1997 so that we can monitor
trends in both occurrence and treatment within the community.
If you have any questions, check with your healthcare provider.
