Prevalence of nosocomial infections in 27 hospitals in the Mediterranean region

ABSTRACT

A multicentre study was conducted in 27 hospitals in Algeria, Egypt, Italy, Morocco and Tunisia to evaluate the prevalence and characteristics of the nosocomial infections. The study population [4634 patients] was relatively young, mean age 41.1 [standard deviation 23.4] years. The prevalence of nosocomial infections was 10.5%; this was higher in non-teaching centres and moderate-sized hospitals. Overall, urinary tract infections were the most common. Paediatric departments rated particularly high [11.3%]. The most commonly isolated organisms were Escherichia coli [17.2%], Staphylococcus aureus [12.5%], Pseudomonas aeruginosa and Klebsiella pneumoniae [9.2% each]. On the day of the study, 40.7% of the patients were under treatment with antibiotics, with nearly half for an empirical indication. Nosocomial infection was significantly associated with mechanical ventilation, hospitalization ? 8 days, presence of a central or peripheral catheter], urinary catheter, diabetes and age
