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 > or = 8 days, presence of a central or peripheral catheter), urinary catheter, diabetes and age.
在阿尔及利亚、埃及、意大利、摩洛哥和突尼斯的27家医院开展了一项多中心研究，以评估医院感染的患病率及特征。研究人群（4634名患者）相对年轻，平均年龄41.1岁（标准差23.4岁）。医院感染的患病率为10.5%；在非教学中心和中等规模医院中这一患病率更高。总体而言，尿路感染最为常见。儿科部门的患病率特别高（11.3%）。最常分离出的微生物为：大肠埃希菌（17.2%）、金黄色葡萄球菌（12.5%）、铜绿假单胞菌和肺炎克雷伯菌（各占9.2%）。在研究当天，40.7%的患者正在接受抗生素治疗，其中近一半是经验性用药。医院感染与机械通气、住院时间≥8天、存在中心或外周导管、导尿管、糖尿病及年龄显著相关。
