This study aimed to estimate the prevalence and risk factors for health-care-associated infection (HAl) in all 9 hospitals of the central-east area of Tunisia in 2005. Of 1373 patients admitted for more than 48 hours, 74 developed HAI, a prevalence of 5.4% (95% CI: 4.2%-6.6%). The prevalence was significantly higher in the intensive care units (18.4%) and neonatal departments (12.7%). There were 79 infections and the most frequent sites of infection were respiratory tract and urinary tract. Microbiological examination was performed for 25 cases of HAl and Pseudomonas aeruginosa was identified in 8 cases. Multiple logistic regression analysis indicated that HAl was linked to diabetes (OR = 2.0), immunosuppression (OR = 3.3), length of stay (OR = 4.5), central venous catheter (OR = 2.5) and peripheral venous catheter (OR= 10.2). We conclude that HAls are of concern in this area of Tunisia.
本研究旨在评估 2005 年突尼斯中东部地区 9 家医院所有患者的医源性感染（HAI）发生率和危险因素。在 1373 名住院时间超过 48 小时的患者中，74 名患者发生了 HAI，发生率为 5.4%（95%CI：4.2%-6.6%）。重症监护病房（18.4%）和新生儿科（12.7%）的发生率明显更高。共有 79 例感染，感染最常见的部位是呼吸道和泌尿道。对 25 例 HAI 进行了微生物学检查，8 例鉴定为铜绿假单胞菌。多因素逻辑回归分析表明，HAI 与糖尿病（OR=2.0）、免疫抑制（OR=3.3）、住院时间（OR=4.5）、中心静脉导管（OR=2.5）和外周静脉导管（OR=10.2）有关。我们的结论是，突尼斯该地区的 HAI 令人担忧。
