Abstract:
Nosocomial infections, or healthcare-associated infections (HAIs), have a significant impact on
more than 1.4 million patients worldwide, according to the World Health Organization, and their
importance is also recognized in Algeria and worldwide. These infections are mainly the result of
inadequate hygiene practices and non-compliance with essential preventive measures, leading to
significant economic losses. Given their frequency and severity, nosocomial infections represent
a major public health issue. In this study, we conducted a survey in a selection of public and private
hospitals in the Ghardaïa region to identify the sources of nosocomial infections and the main types
of bacterial and yeast micro-organisms involved. The ultimate aim is to propose effective solutions
to mitigate and reduce the burden of nosocomial infections. Quantitative analysis of germs found
on medical devices, using the quantitative Brun-Buisson method. The results showed that
nosocomial infections associated with urinary catheters were the most widespread. Infections
associated with pulmonary intubation had a 100% mortality rate in both samples. Among the most
abundant microorganisms, Staphylococcus aureus and Staphylococcus spp. had the highest
percentage at 52%, followed by the Enterobacteriaceae family at 21%, Pseudomonas sp. at 13%
and the yeast Candida albicans at 7%.
