Environmental cleaning is a vital component of infection control. We describe the use of an integrated
infection control protocol in an intensive care unit and its influence on multidrug-resistant organism in-
fection rates. Sustained reductions in multidrug-resistant organism infections can be achieved if individual
processes and weaknesses in intensive care unit environments are identified and addressed in a system-
atic and comprehensive manner.

INTRODUCTION
Multidrug-resistant organisms (MDROs) are the leading cause
of hospital-acquired infections in intensive care units (ICUs).
1
These
organisms include a range of gram-positive and gram-negative bac-
teria that are resistant to 1 or more class of antibiotics.
2
MDROs cause
infections that are more difficult to treat, persist longer, and have
higher mortality and associated health care costs.

Despite various measures, including hand hygiene, personal pro-
tective equipment, and universal precaution measures, MDRO
infection rates continue to remain high.
Prompted by an outbreak of Burkholderia cepacia complex (BCC)
in our ICU, we implemented an integrated infection control proto-
col to address the multiple links in the environmental transmission
of infections. Here we describe the influence of our protocol on
MDRO infection rates in our ICU over a 12-month period.
METHODS
Our surgical ICU (SICU) is a 14-bed unit within our 1,170 bed ter-
tiary care hospital that manages a spectrum of complex medical
and surgical patients. For the first 5 months of the year, 6% of the
admissions (15 cases) to the SICU were noted to be colonized or
infected with BCC.
In response, a quality improvement committee that included
intensivists, environmental services representatives, and infec-
tious disease specialists was convened to design and implement an
infection control protocol.
Before implementation of our new protocol, patient rooms were
routinely cleaned with alcohol-based preparations for disinfec-
tion of small surfaces and with bleach compounds for larger surfaces.
Room sanitation was managed by the hospital EVS with little in-
teraction or input from the other ICU services.
As part of the infection control protocol, all SICU patients were
transferred out and the unit was closed down for a 2-day compre-
hensive cleaning. All patient rooms and the staff stations were
cleaned with hypochlorite solutions and ultraviolet (UV) C radia-
tion. Patient care items were disposed of and all existing ventilators
were replaced. Subsequent to the reopening of the unit, several mea-
sures were introduced.
Daily high-touch point cleaning protocol
A systematic cleaning protocol was implemented that focused
on regular, thorough bleach cleaning of high-touch points on a daily
basis. These high-touch points were specified areas in patient rooms
that were more frequently exposed to human contact and thus more
likely to get contaminated. Disposable microfiber cloths were used
to prevent cross-infection of rooms.
