目的了解医院感染现患率和横断面抗菌药物使用情况。方法采用横断面调查方法,床旁调查和病历调查相结合,将调查日处于医院感染状态的病例进行统计分析。结果实查住院患者840例,医院感染现患率3.33%、例次现患率3.93%;下呼吸道是我院医院感染的主要部位;动静脉插管、气管切开、使用呼吸机、免疫抑制剂,放、化疗是医院感染的主要危险因素;抗菌药物使用率为48.81%。结论医院感染现患率调查方法简单,省时省力,结果可靠;需加强对高危科室目标监测,进一步加强抗菌药物的监控和管理,提高病原学送检率,减少预防用药,降低抗菌药物的使用率,控制医院感染的发生。
Objective To understand the prevalence of nosocomial infections and the use of cross-sectional antimicrobials. Methods The cross-sectional survey method, bedside survey and medical records were combined to make statistical analysis on the cases of hospital infection on the survey day. Results The hospitalized 840 cases were investigated, the prevalence rate of nosocomial infection was 3.33%, and the prevalence rate was 3.93%. The lower respiratory tract was the main site of nosocomial infection in our hospital. Arteriovenous and tracheostomy, ventilator, immunosuppressive agents, Radiotherapy and chemotherapy are the main risk factors of nosocomial infections; the use rate of antibacterials is 48.81%. Conclusion The prevalence rate of nosocomial infection is simple, time-saving and labor-saving, and the results are reliable. It is necessary to strengthen the monitoring of high-risk departments, to further strengthen the monitoring and management of antimicrobial agents, to improve the rate of etiological examination, to reduce the use of preventive drugs and to reduce the use of antimicrobial agents , Control the occurrence of nosocomial infection.
