CDC: 'Nightmare Bacteria' Spreading in Hospitals
Data show more patients
suffering infections from antibiotic-resistant bacteria
A
family of bacteria has become increasingly resistant to
last-resort antibiotics during the past decade, and more
hospitalized patients are getting lethal infections that, in
some cases, are impossible to cure.
The findings,
published March 5 in the Centers for Disease Control and
Prevention's
Vital Signs report, are a call to action for the entire
health care community to work urgently -- individually,
regionally and nationally -- to protect patients. During just
the first half of 2012, almost 200 hospitals and long-term acute
care facilities treated at least one patient infected with these
bacteria.
The bacteria,
carbapenem-resistant Enterobacteriaceae (CRE), kill up to
half of patients who get bloodstream infections from them. In
addition to spreading among patients, often on the hands of
health care personnel, CRE bacteria can transfer their
resistance to other bacteria within their family. This type of
spread can create additional life-threatening infections for
patients in hospitals and potentially for otherwise healthy
people. Currently, almost all CRE infections occur in people
receiving significant medical care in hospitals, long-term acute
care facilities or nursing homes.
"CRE are nightmare
bacteria. Our strongest antibiotics don't work and patients are left
with potentially untreatable infections," said CDC Director Tom Frieden,
M.D., M.P.H. "Doctors, hospital leaders and public health must work
together now to implement CDC's 'detect and protect' strategy and stop
these infections from spreading."
Enterobacteriaceae are a
family of more than 70 bacteria including Klebsiella pneumoniae and E.
coli that normally live in the digestive system. Over time, some of
these bacteria have become resistant to a group of antibiotics known as
carbapenems, often referred to as last-resort antibiotics. During the
last decade, CDC has
tracked one type of CRE from a single health care facility to health
care facilities in at least 42 states. In some medical facilities, these
bacteria already pose a routine challenge to health care professionals.
The Vital Signs report
describes that although CRE bacteria are not yet common nationally, the
percentage of Enterobacteriaceae that are CRE increased fourfold in the
past decade. One type of CRE, a resistant form of Klebsiella pneumoniae,
has shown a sevenfold increase in the last decade. In the U.S.,
northeastern states report the most cases of CRE.
According to the report,
during the first half of 2012, 4 percent of hospitals treated a patient
with a CRE infection. About 18 percent of long-term acute care
facilities treated a patient with a CRE infection during that time.
In 2012, CDC released a
concise, practical CRE
prevention toolkit with in-depth recommendations for hospitals,
long-term acute care facilities, nursing homes and health departments.
Key recommendations include:
- enforcing use of infection control precautions (standard and
contact precautions)
- grouping patients with CRE together
- dedicating staff, rooms and equipment to the care of patients
with CRE whenever possible
- having facilities alert each other when patients with CRE
transfer back and forth
- asking patients whether they have recently received care
somewhere else (including another country)
- using antibiotics wisely
In addition, CDC
recommends screening patients in certain scenarios to determine if they
are carrying CRE. Because of the way CRE can be carried by patients from
one health care setting to another, facilities are encouraged to work
together regionally to implement CRE prevention programs.
These core prevention
measures are critical and can significantly reduce the problem today and
for the future. In addition, continued investment into research and
technology, such as a testing approach called Advanced Molecular
Detection (AMD), is critical to further prevent and more quickly
identify CRE.
In some parts of the
world, CRE appear to be more common, and evidence shows they can be
controlled. Israel recently employed a coordinated effort in its 27
hospitals and dropped CRE rates by more than 70 percent. Several
facilities and states in the U.S. have also seen similar reductions.
"We have seen in outbreak after outbreak that when facilities and
regions follow CDC's prevention guidelines, CRE can be controlled and
even stopped," said Michael Bell, M.D., acting director of CDC's
Division of Healthcare Quality Promotion. "As trusted health care
providers, it is our responsibility to prevent further spread of these
deadly bacteria."
