hospital-acquired infections, about a tenth of which occur in wounds, has
propelled the issue of prevention to the top of the health-care agenda.
Policy centres on hygiene, protective precautions and educating staff and
patients. This article focuses on detection and treatment options for
confirmed wound infections. |

University of Brussels, Department of Intensive Care, Erasme Hospital,
Brussels, Belgium. jlvincen@ulb.ac.be Nosocomial
infections are common in many hospital departments, but particularly so on
the intensive care unit, where they affect some 20 to 30% of patients.
While early diagnosis and appropriate treatment are, of course, important,
perhaps the greatest challenge is in the application of techniques to
limit the development of such infections. This review will briefly discuss
some of the background pathophysiology and epidemiology of nosocomial
infection, and then focus on general and infection-specific preventative
strategies individually and as part of broader infection-control programs
with infection surveillance. |

Cycling empirical antimicrobial agents to prevent emergence of
antimicrobial-resistant Gram-negative bacteria among intensive care unit
patients. Crit Care Med. 2004 Dec; 32(12):2450-6. Department
of Medicine, Washington University School of Medicine, St. Louis, MO
63110, USA. dwarren@im.wustl.edu OBJECTIVE:
To determine the impact of the rotation of antimicrobial agents on the
rates of infection, intestinal colonization, and acquisition with
antimicrobial-resistant Gram-negative bacteria. DESIGN: Pre- and
postintervention design. SETTING: A 19-bed, medical intensive care unit.
PATIENTS: Individuals admitted to the study unit for >48 hrs.
INTERVENTIONS: After a 5-month baseline observation period, four classes
of antimicrobial agents with Gram-negative activity were cycled at 3- to
4-month intervals for 24 months. MEASUREMENTS AND MAIN RESULTS: The
primary outcome was the acquisition rate of antimicrobial resistance among
Enterobacteriaceae
and
Pseudomonas aeruginosa obtained from rectal swab cultures performed on
admission, weekly during the patients' stay, and at discharge. Rates and
microbiology of nosocomial bloodstream infections and
ventilator-associated pneumonia were also compared between baseline and
cycling periods. The cycling program resulted in a significant change in
prescribing practices; the predominant agent used changed with each cycle.
Among study patients who were not already colonized with a resistant
organism, the rate of acquisition of enteric colonization with bacteria
resistant to any of the target drugs remained stable during the cycling
period for P. aeruginosa (relative rate, 0.96; 95% confidence Interval,
0.47-2.16) and Enterobacteriaceae (relative rate, 1.57; 95% confidence
interval, 0.80-3.43). Hospital-wide, P. aeruginosa from routine clinical
cultures resistant to the target drugs increased during the cycling
period. The proportion of Gram-negative bacteria isolated from cases of
nosocomial bloodstream infection (29% baseline vs. 26% cycling; p = .11)
and ventilator-associated pneumonia (80% vs. 41%; p = .06) did not
significantly differ. CONCLUSIONS: In this study, antimicrobial cycling
did not result in a significant change in enteric acquisition of resistant
Gram-negative bacteria among intensive care unit patients. |

Tokyo 113-8421, Japan. As
a measure for the prevention and control of nosocomial infections in
medical school students, we examined the students' titers of antibodies to
measles, rubella, varicella, and mumps viruses to determine whether
vaccination was required. We also analyzed and discussed correlations
among antibody titers to the viruses. Subjects were 363 Juntendo
University students, ranging from freshmen to seniors. EIA was used to
measure IgG antibody titers. Eight subjects (2.2%) had negative titers for
measles, 36 (9.9%) for rubella, 8 (2.2%) for varicella, and 10 (2.7%) for
mumps. Seronegative subjects were vaccinated against each virus and high
seroconversion rates were obtained: 100% for measles and rubella, 67% for
varicella, and 89% for mumps. In addition, we used Pearson's test to
search for correlations among the antibody titers for each virus. A weak
correlation was observed among antibody titers for measles, rubella, and
mumps but not for varicella. These results suggest that MMR vaccine might
be effective in people with low levels of antibody to measles, rubella,
and mumps. |

tubing a contributor to the failure of cleaning and decontamination? J
Hosp Infect. 2004 Nov; 58(3):224-9. Department
of Infectious Diseases and Immunology, University of Sydney and The
Australian Centre for Hepatitis Virology, Sydney, NSW 2006, Australia. We
predicted that biofilm would form on surfaces of endoscope tubing in
contact with fluids, and may be difficult to remove by current washing
procedures. Its presence may protect micro-organisms from disinfectant
action and contribute to failure of decontamination prior to re-use.
Tubing samples removed from 13 endoscopes that had been sent to an
endoscope-servicing centre were examined for the presence of biofilm and
bacteria by scanning electron microscopy. Biological deposits were present
on all samples tested. Biofilm (bacteria plus exopolysaccharides matrix)
was present on the suction/biopsy channels of five of 13 instruments, and
was very extensive on one of these. Bacteria and microcolonies were often
but not necessarily associated with surface defects on the tubing. All 12
air/water channels examined showed biofilm, and this was extensive on nine
samples. Routine cleaning procedures do not remove biofilm reliably from
endoscope channels, and this may explain the unexpected failure of
decontamination encountered in practice despite good adherence to
infection control guidelines. |

J, Hodgson G, Kerr KG. Provision of safe
potable water for immuno- compromised patients in hospital. J Hosp Infect.
2004 Oct; 58(2):155-8. Department
of Infection Control, Leeds Teaching Hospitals Trust, Leeds, UK. We
conducted a survey of hospital drinking water provision for patients with
immunocompromising conditions in 15 Trusts in the north of England. Ten
trusts replied, reporting on provision of drinking water in 14 separate
units. Of these, nine provided only tap water to all patients,
irrespective of underlying condition. In two units, iced water, with ice
from commercially available makers, was used. Five units distinguished
between neutropenic and non-neutropenic patients, with the former group
receiving cooled, boiled water (three units), sterile water and sterile
water or carbonated water (one unit each). No unit provided filtered
water. Water in jugs was changed daily, twice daily or only when empty in
seven, three and four units, respectively. On 10 units, patients were
allowed to provide their own drinking water, but no unit provided written
advice to patients on potable water. A survey within our own Trust
revealed similar inter-unit disparity. The options for potable water
provision were reviewed, taking into account: microbiological quality,
organoleptic (perceived taste/smell) acceptability, cost and factors
relating to staff safety and patient confidentiality [as it was possible
for human immunodeficiency virus (HIV) seropositive patients on some wards
to be identified because they were provided with cooled, boiled water]. It
concluded that end-line commercially available water filters were the
optimal way to provide drinking water to immunocompromised patients in
hospital. |
