肿瘤患者医院感染的流行病学调查

Hospital Infection Investigation in Tumor Patients

目的 了解某院 2 0 0 0年肿瘤住院患者的医院感染发病情况及其影响因素 ,为制定预防医院感染的措施提供依据。方法 收集整理该院 2 0 0 0年肿瘤住院的病历资料 ,填写统一的个案登记表 ,建立数据库 ,进行描述性统计分析。结果 本研究调查肿瘤住院病例 977例次 ,发现医院感染 2 37例次 ,发病率为 2 4 3% ;男性感染率为2 2 1% ,女性感染率为 2 9 6 % ,两者间差异有显著性 ;发病率随年龄的增加而增加 ;有、无医院感染的患者死亡率分别为 2 4 1%、2 7% ,差异有显著性 ,相对危险度为 11 4 ;感染最易发生在下呼吸道。结论 医院感染增加了患者死亡的危险性 ,客观上促进了患者的死亡 ,为减少医院感染的发生 。

OBJECTIVE To understand the incidence and affecting factors of hospital infection in tumor patients and provide basis for preventing hospital infection. METHODS To collect and arrange materials from their medical record of inpatients, set up data storage system and give a description of analyses. RESULTS Among 977 cases/times, 237 ones had hospital infection, the morbidity rate was 24.3%. The rate of male was 22.1%, female 29.6%, which show significant difference. The relative risk was 11.4; the most common position of infection was lower respiratory tract. CONCLUSIONS Hospital infection increases the risk of death, in order to reduce the hospital infection in aged patients and the infection of respiratory tract should be controlled.
