Prevalence of Nosocomial Infections
in Adult Intensive Care Units at
a Kosova Teaching Hospital
To the Editor—Nosocomial infections constitute an important
public health challenge worldwide. They result in high mor-
bidity and mortality, prolonged hospital stays, greater use of
antibiotics, and increased costs.'
,2
The burden of this problem
is highest in intensive care units (ICUs). Nosocomial infection
rates in ICUs, even in highly developed countries, are 25%-
35%, with mortality exceeding 25%, whereas in developing
countries, two-thirds of patients admitted to intensive care
suffer at least 1 nosocomial infection.

We report on a survey
of the prevalence of nosocomial infection in adult ICUs at
the University Clinical Centre of Kosova (UCCK).
The health care sector in Kosova has scarce human and
material resources. It receives only €35 per capita per year.
Infection control in Kosova is taking the first steps towards
establishing national policies in prevention and control of
nosocomial infections. In the past, within the UCCK and 5
county hospitals, hospital infection control committees ex-
isted solely on paper. The awareness of nosocomial infection
increased during the last few years, and, in May 2006, the
Ministry of Health established the National Committee for
Prevention and Control of Nosocomial Infections as the ex-
ecutive body to combat this challenge. The first study of the
prevalence of nosocomial infections in targeted high-risk ar-
eas, undertaken in 2003 at UCCK, showed an overall prev-
alence of 17.4% (29 infections in 167 patients).

The UCCK is the only tertiary care center in Kosova. It
has 2,400 beds and serves 2.1 million inhabitants. Our study
used a point prevalence methodology and was performed on
September 15, 2006, in the 3 ICUs at UCCK. Patient data
were obtained from medical records and by physical exam-
ination. Data on the following types of infection were re-
corded: nosocomial pneumonia, nosocomial urinary tract in-
fection, surgical site infection, and nosocomial bloodstream
infection. The US Centers for Disease Control and Prevention
criteria were used to define nosocomial infections.

Specimens
of endotracheal aspirate, sputum, and urine, as well as nasal,
throat, axillar, and perineal swab specimens, were obtained
from all patients. Diagnostic bacteriologic testing was done
using standard procedures in the Department of Microbi-
ology at the National Institute for Public Health of Kosova.
Of 28 patients surveyed, 11 had a total of 18 nosocomial
infections. Of these 18 nosocomial infections, which all oc-
curred in the central ICU, ventilator associated pneumonia
accounted for 8 (44.4%), bloodstream infections for 5
(27.8%), urinary tract infections for 4 (22.2%), and surgical
site infection for 1 (5.6%).
The overall prevalence rate was 64.3%. The mean age of
the patients was 42.1 years (SD, 15.3 years). The median
length of stay before the survey was 17.3 days (range, 2-112
days). No infections were detected in the pulmonological and
neurological ICUs. In the central ICU, 68.7% of patients had
nosocomial infections, with a predominance of ventilator as-
sociated pneumonia (72.7% of infections).
Laboratory testing yielded isolates for 26% of patients.
Gram-negative bacilli represented 63.6% of all isolates, with
a predominance of Acinetobacter species (27.2%) and Pseu-
domonas aeruginosa (18.2%). Of the 28 surveyed patients, 17
(60.7%) were receiving antimicrobial treatment at the time
of the survey.
The prevalence of nosocomial infections in Kosova is
higher than in other European countries, where estimates
range from 20% to 35%.
6
The high prevalence in Kosova can
be attributed to many factors: a lack of financial support,
inadequate numbers of trained personnel working in infec-
tion control, understaffed hospital units, and insufficient
equipment and supplies. These results emphasize the need
for infection prevention interventions in ICUs.
