摘要
目的探讨医院获得性肺炎发生的危险因素,为制定防治策略和措施提供科学依据。方法收集山西省太原市3所医院2005年1月1日~2005年12月31日医院获得性肺炎患者191例作为病例组,同期未发生肺炎的住院患得191例作为对照组。采用病例对照单因素及Logisitic多因素分析筛选出可能的危险因素。结果年龄≥60岁、基础疾病、联合使用〉2种的抗生素、入住重症监护室(ICU)、住院时间≥21 d、插管机械通气或雾化吸氧为独立的6个危险因素,其相对危险依次为3.589,2.472,2.217,2.171,2.157和2.039。结论医院获得性肺炎的发生受很多因素的影响,各因素之间存在着非常复杂的相互作用,应针对危险因素采取相应措施进行预防和控制。
Objective To explore the risk factors of nosocomial pneumonia (NP) and to provide scientific evidence for the preventive strategy of NP. Methods Overall 191 adult patients with NP and 191 adult patients without NP were collected from three hospitals in Taiyuan area from January 2005 to December 2005. The method of case-control study ,one-way and multiple factor logistic regression were used to analyze the risk factors of NP. Results The independent risk factors of NP were being equal to or elder than 60(RR =3. 589) ,previous disease(RR =2. 472) ,treatment with more than two antibiotics(RR =2. 217) ,hospitalization in intensive care unit(RR =2. 217) ,hospitalization more than 21 days(RR =2. 157) ,and treatment with cascade humidification system ( RR = 2. 039 ). Conclusion The occurrence of NP is influenced by a lot of factors with complicated interaction. The preventive strategy and measures should be focused on the risk factors.
