ABSTRACT
Background: the possibility of nosocomial infection is determined
by factors relating to the patient, the presence and degree of immunodeficiency,
and interventions that become stronger the risk.
A nosocomial outbreak is the emergence of an unusual case of a
specific disease and is due to an infectious agent only. Our objective
was to analyze the risk of Burkholderia cepacia with a risk
stratification criterion in a pediatric intensive care unit (ICU).
Methods: an epidemiological outbreak, transverse, retrospective
study was done. We included 71 patients from a pediatric ICU.
Attack rate and fatality rate was obtained. We applied Fisher exact
test with a level of significance
p ‹ 0.05.
Results: regardless the risk stratification the Burkholderia cepacia
infection showed no significant difference. The attack rate was 23.94,
and the fatality rate in infected patient was 29.41. Candida albicans
coinfection was present in 50 % of the cases; other kind of bacteria
infection in 50 %was also seen. Therefore the treatment was the
combination of different antimicrobials.
Conclusions: the paediatric intensive care patient is exposed to
nosocomial infection including Burkholderia cepacia independent
of its risk rating. Attachment and the monitoring of standard
precautions with isolation strategy is suggested as a good preventive
measure.
