住院患者医院感染危险因素的Logistic回归分析

目的探讨现住院患者医院感染的高危因素。方法采用床旁调查与病历调查相结合的方法调查964例现住院患者1d的医院感染情况，并对可能危险因素进行Logistic回归分析。结果现住院患者964人，发生医院感染81例，现患率为8．40％，医院感染部位居前三位的为下呼吸道占29．03％，泌尿道占22．58％，胃赐道占11．83％。泌尿道插管、气管切开、免疫抑制剂、脑血管病、抗生素使用、基础疾病诊断数目≥3等是医院感染的高危因素。结论严格无菌技术、加强对接受侵入性操作患者的护理，合理使用抗生素、增强患者免疫力是降低医院感染发生率的关键。

Risk factors for nosocomial infection of inpatients:a logistic regression analysis

Aim To investigate the high risk factors of nosocomial infection in inpatients. Method 964 inpatients were investigated by surveying of bed-side and case recorder for nosocomial infection and possible risk factors during one day in our hospital, and these factors were analyzed by logistic regressive analysis. Results Among 964 inpatients,81inpatients suffered the nosocomial infection, and prevalence rate was 8.40%. Low respiratory tract, urinary tract and gastrointestinal tract infection constituent ratioes were 29.03% , 22.58% and 11.83 % respectively. The high risk factors of nosocomial infection were as follows indwelling catheter,tracheotomy, immunosuppressive agents, cerebral vascular disease, number of basic diseases ≥ 3 and antibiotic use. Conclusion It was very important role in reducing nosocomial infection rate that asepsis was strictly carried into effect, patients who received invasive operation were intensively nursed, antibiotics were reasonably used and simultaneously immunity was strengthened in our hospital.
