Hospital suggests HIV tests to 27
patients after sterilization error
• Swedish Medical Center continues to investigate why staff did
not properly sterilize a piece of ultrasound equipment,
potentially compromising the health of 27 patients.
• The unsterilized equipment was used between September 19
and December 10.
• Swedish Health Services has checked other facilities that
perform the same procedure to ensure the same mistake
doesn't happen.
• They're advising all 27 patients affected to undergo an
immediate blood test, then a second one in three months.
• Chief Medical Officer Dr. John Vassall calls the mistake a "human
error," one they're still investigating. Of the four
decontamination steps taken, staff missed the last one.
• The hospital estimates the possibility of infection is less than one
in a million.

Greenville hospital error in
cleaning for urological procedure
• Charles A. Dean Memorial Hospital and Northwoods Healthcare announced
Thursday that patients who underwent certain urological exams could have
experienced greater risk of infection after the medical facilities discovered an
error in their cleaning procedure done before cystoscopies.
• 76 patients who had a cystoscopy between Sept. 9, 2011 and Oct. 25, 2013
were notified of the error and will be offered follow-up services at no cost.
• During a routine infection control surveillance, it was discovered they were not
cleaning cystoscopes according to the manufacturer’s recommendations.
• A pre-cleaning step was skipped prior to the scope being disinfected
• Steps are being taken to ensure that the issue doesn’t happen again
• Mandatory staff retraining, reviewing and adjusting policy, improvements to the
procedure area and adhering to the manufacturer’s guidelines are steps being
implemented.

Legionnaire’s in VA
Medical Centers
• As many as 21 veterans contracted Legionnaires' disease
between February 2011 and November 2012 from bacteriatainted tap water at VA campuses in Oakland and O'Hara,
according to the Centers for Disease Control and Prevention.
A review by the VA Office of Inspector General found the
Pittsburgh VA did not follow established guidelines in combating
the waterborne Legionella bacteria that cause Legionnaires'
disease, a severe form of pneumonia.
• House Committee on Veterans' Affairs is continuing its
investigation into the outbreak

Lutheran General finds
and stops bacteria source
• Advocate Lutheran General Hospital in Park Ridge is asking patients who had a
specific procedure performed earlier this year to be screened for a potential
infection that's highly resistant to antibiotics. Hospital officials also are assuring
the public that the procedure has now been made completely safe. It's believed
243 patients who underwent an Endoscopic Retrograde
Cholangiopancreatography, or ERCP, procedure between January and September
this year may have been exposed to the bacteria known as carbapenum-resistant
enterobacteriaceae, or CRE.
• It's possible that one patient unknowingly carrying the drug-resistant bacteria
was the source of the contamination. The earliest clue came when five or six
patients were found to have contracted it. The CDC, FDA and local public health
dept are assisting in the investigations. While the manufacturer's
recommendation for cleaning the equipment for ERCPs involves a process of
high-grade disinfectants and brushes, Lutheran General has permanently moved
to the use of gas sterilization — the same as is used for operating room
equipment. Source: The Daily Herald December 27, 2013
New Delhi Metallo-β-Lactamase–Producing Escherichia
coli Associated with Endoscopic Retrograde
Cholangiopancreatography — Illinois, 2013
• From March to July 2013, 9 patients with positive cultures for NDM-producing
Escherichia coli (eight clinical cultures and one rectal surveillance culture) were
identified in northeastern Illinois. A case control study was done and showed a
history of undergoing endoscopic retrograde cholangiopancreatography (ERCP)† at
hospital A was strongly associated with case status (6 of 8 (75%) versus one of 27
controls. After manual cleaning and high-level disinfection in an automated
endoscope reprocessor, cultures were obtained from the ERCP endoscope used on
five of the case-patients. NDM-producing E. coli and KPC-producing K. pneumoniae
were recovered from the terminal section (the elevator channel) of the device. The
E. coli isolate was highly related (>95%) to the outbreak strain by PFGE.
Retrospective review and direct observation of endoscope reprocessing did not
identify lapses in protocol. Among 91 ERCP patients who were initiallty notified
that they had potential exposure to a culture-positive endoscope, 50 returned for
rectal surveillance cultures. NDM-producing E. coli were recovered from 23 (46%)
An additional 12 patients with NDM-producing CRE have been identified in
northeastern Illinois, bringing the total during January–December 2013 to 44.

Toys, Books, Cribs Harbor
Bacteria for Long Periods
University at Buffalo research published today in Infection and Immunity shows
that Streptococcus pneumoniae and Streptococcus pyogenes do persist on surfaces
for far longer than has been appreciated. The findings suggest that additional
precautions may be necessary to prevent infections, especially in settings such as
schools, daycare centers and hospitals.
The researchers found that in the day care center, four out of five stuffed toys
tested positive for S. pneumonaie and several surfaces, such as cribs, tested
positive for S. pyogenes, even after being cleaned. The testing was done just prior
to the center opening in the morning so it had been many hours since the last
human contact.
Researchers became interested in the possibility that some bacteria might persist
on surfaces when they published work last year showing that bacteria form biofilms
when colonizing human tissues. They found that these sophisticated, highly
structured biofilm communities are hardier than other forms of bacteria.

Study Shows HCWs Hands
Contaminated with C. difficile
After Routine Care
A new study finds nearly 1 in 4 healthcare workers’ hands were contaminated with
Clostridium difficile spores after routine care of patients infected with the bacteria.
Researchers compared hand contamination rates among healthcare workers caring
for patients with C. difficile with healthcare workers caring for non-colonized
patients after routine patient care and before hand hygiene. All patients with C.
difficile were being treated with infection control measures that consisted of (1)
placing patients into a single-bed room with dedicated equipment; (2) wearing
disposable gowns with full-length sleeves and a pair of gloves on entering the
room; (3) hand hygiene with alcohol-based handrub before wearing gloves, before
and after body fluid exposure, and handwashing with medicated soap and water
followed by use of alcohol-based handrub after glove removal; and (4) daily room
cleaning with a hypochlorite-based disinfectant. Contamination of healthcare
workers’ hands occurred with high-risk contact (e.g., patient washing, digital rectal
exam, bed linen change, colonoscopy) or when workers didn’t use gloves. Hand
contamination was also associated with the duration of high-risk contact and was
more common among nursing assistants (42 percent) than among other
healthcare workers (19 percent for nurses and 23 percent for physicians).

Hospital asks some patients to
get hepatitis C test
• Poudre Valley Hospital in Fort Collins, CO, mailed letters to 210 adults
who were treated between Sept. 1, 2011, and Aug. 28, 2012,
recommending they be tested for hepatitis C. While there have been no
reported cases of patients acquiring hepatitis C at the hospital and no
evidence of harm to patients, PVH wants to ensure that these patients
are absolutely safe.
• A former employee was suspected of diverting prescription painkillers
may have, during the established time period, put some patients at risk
for exposure to hepatitis C. The Colorado Department of Public Health
and Environment have confirmed between Sept. 1, 2011, and Aug. 28,
2012, the employee had or might have had hepatitis C. Poudre Valley
Hospital has been working on this case with the CDPHE since early in
November 2013.

Scientists discover how some
bacteria avoid antibiotics
Unlike drug-resistant bacteria that have evolved their ability to resist antibiotics
through mutation, persistent bacteria do not resist the drugs but simply lie
dormant or inactive while exposed to them. Then, when the treatment is over,
they "wake up" and continue with their harmful activity. It is the bacteria's ability
to lie dormant and then wake up once the threat to them had passed that has
puzzled scientists.
Until now, it had been known that there is a connection between these kind of
bacteria and the naturally occurring toxin HipA in the bacteria, but scientists did
not know the cellular target of this toxin and how its activity triggers dormancy
of the bacteria.
The research showed that when antibiotics attack these bacteria, the HipA toxin
disrupts the chemical "messaging" process necessary for nutrients to build
proteins. This is interpreted by the bacteria as a "hunger signal" and sends them
into an inactive state, (dormancy) in which they are able to survive until the
antibacterial treatment is over and they can resume their harmful activity.
