目的 探讨肿瘤患者放疗后发生医院感染的影响因素.方法 选择放疗科收治的1 000例放疗患者作为研究对象,分析发生医院感染的相关影响因素.结果 1 000例癌症放疗患者发生医院感染68例,感染率为6.8％,感染部位以呼吸道和肺部为主,分别占29.41％和26.47％;年龄≥65岁、有糖尿病史、住院时间≥30 d、TNM分期Ⅲ～Ⅳ期、同步放化疗、有侵入操作(PICC)均为发生放疗后感染的相关危险因素(P ＜0.05或P ＜0.01).结论 肿瘤患者放疗后发生医院感染的危险因素较多,应做好相应的预防与控制措施,以降低医院感染发生率.%Objective To analyze risk factors of nosocomial infections in cancer patients after undergoing radiotherapy. Methods A total of 1 000 tumor patients receiving radiotherapy were chosen as the study objects. The related factors of nosocomial infections were analyzed. Results Out of 1 000 tumor patients, there were 68 cases with nosocomial infections, accounting for 6. 8％, and the infections were mainly located in respiratory tract (29. 41％), and lungs (26. 47％). Age≥65, diabetes history, hospital stay≥30 d, Ⅲ to Ⅳ stages of TNM classification, simultaneous radiotherpy and chemotherapy, and invasive operation (PICC) were found to be risk factors of nosocomial infection (P ＜ 0. 05 or P ＜ 0. 01). Conclusion Risk factors of nosocomial infections are varied. Hence the prevention and control measures should be taken correspondingly to decrease the hospital infection rate.
