CHICAGO (AP) — Testing all new hospital patients for a dangerous staph
“superbug” could help wipe out a germ that likely kills more Americans than
AIDS, consumer advocates say and early evidence suggests.
Yet few U.S. hospitals do it, and many fight efforts to require it. Why?
Jeanine Thomas, who nearly died from the drug-resistant staph bug, says the
reason is simple: “Doctors don’t want to be told what to do.”
The Chicago suburbanite’s personal crusade led Illinois this year to become
the first state to order testing of all high-risk hospital patients and
isolation of those who carry the staph germ called MRSA.
Powerful doctor groups fought against it. The testing and isolation of
patients would be too costly, they said. Many other germs plague hospitals
that also require attention. Experts said a more proven approach would focus
on better hand washing by hospital staff — a simple measure tough to enforce.
Yet, Thomas prevailed. Similar measures passed this year in Pennsylvania and
New Jersey. And Thomas’ national crusade to make hospitals test for MRSA and
report their infection rates gained steam last week after a Virginia
teenager’s death from the germ and a government report estimated it causes
dangerous infections that sicken more than 90,000 Americans each year and
kill nearly 19,000.
Suddenly the little-known germ with the cumbersome name,
methicillin-resistant Staphylococcus aureus, is getting lots of attention.
People in health care settings, like hospitals and nursing homes, are most at
risk for MRSA infections. Doctors and nurses who treat staph-infected
patients and then don’t carefully wash up can spread the germ to other
patients. Germ-contaminated medical devices used on people having dialysis or
medical procedures also can spread staph. Older patients and blacks are most
at risk, according to the recent report by government researchers.
MRSA, pronounced Muhr-suh, has been around for decades and in recent years
has spread to schools, prisons and crowded public housing projects. Even
healthy people can carry it on their skin. It may look like a pimple or
spider bite that doesn’t heal, but it can turn deadly if it enters the
bloodstream or morphs into a flesh-eating wound.
Yet, many infection control experts oppose required testing for it in
hospitals.
Many note that MRSA is just one of dozens of risky germs that often infect
people in hospitals — particularly those with weakened immune systems or open
wounds.
But Lisa McGiffert doesn’t buy it. The director of the Consumers Union’s
campaign to stop hospital infections calls that “an argument of distraction.”
“Certainly there are other superbugs and they should be tackling those, too,”
said McGiffert. “To eradicate hospital-acquired infections is going to take a
comprehensive effort” that should include testing hospital patients, she
said.
About 1.7 million Americans each year develop infections from various germs
while hospitalized and almost 100,000 of them die, according to the U.S.
Centers for Disease Control and Prevention.
MRSA accounts for only about 10 percent of these infections. Other worrisome
bugs include C-difficile (an intestinal infection), vancomycin-resistant
Enterococcus (linked with intestinal, skin and blood infections), and
drug-resistant Acinetobacter (which can cause pneumonia, skin and blood
infections); none of them accounts for more than 10 percent of hospital
infections.
MRSA infections have hogged attention, partly because they’re on the rise.
And, acknowledges the CDC’s Dr. John Jernigan, “MRSA likely accounts for a
disproportionate amount of illness and death” because of its strength and
resistance to mainline antibiotics.
CDC recommendations for fighting drug-resistant bugs list MRSA testing as an
option. However, the agency says it’s unclear whether that works better than
other measures. Those include judicious use of antibiotics, hand washing, and
wearing gloves, gowns and other protective gear. “We don’t think (testing is)
a silver bullet to that problem,” Jernigan said.
The Joint Commission, an independent, nonprofit group that sets standards for
the nation’s hospitals, doesn’t have specific rules on how to prevent MRSA.
The commission’s Dr. Robert Wise said the organization wants to see evidence
that MRSA testing and other measures work. He said the commission hopes to
have an answer early next year and then will then decide whether to adopt new
standards.
Perhaps the commission will review an experiment done in Pittsburgh. There,
the Veterans Affairs hospital tried MRSA testing, and annual infection rates
fell from about 60 to 18 cases, said Dr. Rajiv Jain.
The staph bug used to cause “occasional” deaths, but no patient has died
since 2005 when testing of all patients began, said Jain, who is with the
VA’s MRSA prevention program.
In May, the VA began putting a $28 million testing system in place for all
155 hospitals. But it costs about $32,000 to treat one hospitalized MRSA
patient, so “if you reduce infections by 50 percent, you more than recuperate
the cost,” Jain said.
Denmark, Iceland, Norway, and the Netherlands have reduced their MRSA rates
and all test high-risk patients. In the Netherlands, that means testing
foreign patients.
Opponents of mandatory testing point out that these small countries all had
low rates of the germ to begin with. Hospitals in larger, more diverse
nations like Britain, for example, have long had problems with MRSA.
And testing may not make sense for hospitals that treat few high-risk
patients or where other bugs are more prevalent, opponents say.
“The best approach is not to have state legislators dictating how hospitals
go about fighting infections, said Dr. Don Goldmann, of the Institute of
Healthcare Improvement, a nonprofit advocacy group.
At the University of Chicago Medical Center, doctors have been focusing on
C-difficile bacteria, which can cause severe intestinal illness.
With Illinois’ new law requiring MRSA testing, “We’re having to shift gears
and haven’t been able to devote what we’d hoped on these other pressing
problems,” said Dr. Stephen Weber, the hospital epidemiologist.
At Chicago’s Rush University Medical Center, lab supplies alone for the
testing will likely cost about $80,000, said Stacy Pur, Rush’s chief nurse
epidemiologist for infection control. “It’s very labor-intensive and we would
really much rather focus our efforts on infection control” measures proven to
work, including better hand washing by hospital staff, she said.
But Thomas, the MRSA patient-turned-advocate, argues: “You’re never going to
control this with hand hygiene, because you’re never going to get 100 percent
compliance.”
Thomas had never heard of MRSA until she slipped on ice seven years ago and
broke her left ankle. That landed her in a Chicago hospital, where she
believes she got the infection.
Two days after being sent home, she developed throbbing pain in her left leg.
She went to the emergency room, where doctors removed her splint and found
the ankle hugely swollen, black and draining pus. She was admitted and given
antibiotics, but within a week the infection spread inside her body; her
lungs, kidneys and other vital organs shut down.
Hospitalized for three weeks and bedridden for six months, she recovered but
her ankle joint was destroyed. She formed a support group and began lobbying
for the new law.
Now Thomas is working with advocates in several other states.
And if Illinois hospitals don’t comply, she may push to enact testing of all
— not just high-risk — hospital patients.
That has been done since 2005 at three Chicago area hospitals in the Evanston
Northwestern Healthcare system.
There, the MRSA infection rate has dropped 60 percent, said the system’s Dr.
Lance Peterson.
And at the VA hospital in Pittsburgh, Jain reported an added bonus. The rates
for other hospital-acquired infections also fell after MRSA testing began.
Why? The testing may have caused hospital workers to pay more attention to
hand washing and other prevention efforts, he said.
