【摘要】 目的 :分析老年护理医院患者院内感染病原菌特点及耐药性,探讨其危险因素和防治的相应措施。方法 :采用回顾性调查分析方法。结果 :739例患者中发生院内感染96例(13.0%)。感染部位以呼吸道为主,病原菌以革兰氏阴性菌为主,且耐药率高。老年护理院院内感染率高于全国一般医院水平,且随住院时间的延长及年龄的上升而增加。结论 :患者身体的低功能状态是一种常见的危险因素,可导致产超广谱β-内酰胺酶细菌和耐甲氧西林金黄色葡萄球菌定植。合理使用抗菌药物是防治院内感染的有效措施。更多还原

【Abstract】 Objective: To analyze the characteristics and drug resistance of pathogens in nosocomial infection in an elderly nursing hospital and to explore the risk factors and corresponding measures for their prevention and treatment. Methods:The data from 739 patients were retrospectively analyzed. Results: Ninety-six cases of patients were diagnosed as nosocomial infections(accounting for 13.0%) and the main infection site was at respiratory tract and the main pathogens with higher drug resistance was Gram-negative bacteria. The incidence of nosocomial infection in the elderly nursing hospital was higher than that in the general hospitals in China and was increased with the extension of hospital stay and age rise of patients. Conclusion:The low functional status of the patients is a common risk factor resulting in the colonization of bacteria producing extended spectrum β-lactamases and methicillin-resistant Staphylococcus aureus. Rational use of antibacterials is an effective measure for the prevention and treatment of nosocomial infection.更多还原
