Étude sur les infections nosocomiales d’origine levurienne et bactérienne dans quelques structures hospitalières de la wilaya de Ghardaïa

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%.
