目的了解住院老年患者医院感染特点及其危险因素,制定有效控制措施。方法采用回顾性调查方法,对某医院2008-2010年所有住院老年患者医院感染发生率及相关因素进行了调查与分析。结果该医院3年共有住院老年患者6 128例,发生医院感染452例、576例次,医院感染率为7.37%、例次感染率9.40%。感染部位以呼吸道为主,占42.86%;其次为泌尿道感染,占33.19%。患者年龄、住院天数、气管插管、尿道插管、基础病等构成老年患者医院感染的主要危险因素。结论该医院住院老年患者医院感染发生率明显高于同期医院感染水平,侵入性操作和严重的基础病构成老年患者医院感染主要危险因素,应有针对性地采取防控措施。
Objective To understand the characteristics of nosocomial infections in hospitalized elderly patients and its risk factors and to develop effective control measures. Methods A retrospective survey was conducted to investigate the prevalence and related factors of nosocomial infections among all hospitalized elderly patients in a hospital from 2008 to 2010. Results A total of 6 128 hospitalized elderly patients were hospitalized in this hospital. There were 452 hospitalized cases and 576 hospitalized cases. The hospital infection rate was 7.37% and the infection rate was 9.40%. Infected parts mainly respiratory tract, accounting for 42.86%; followed by urinary tract infection, accounting for 33.19%. The patient’s age, length of hospital stay, endotracheal intubation, urethral intubation, and underlying diseases constitute the major risk factors for nosocomial infections in elderly patients. Conclusion The incidence of nosocomial infection in hospitalized elderly patients is significantly higher than that of nosocomial infections in the same period. Intrusive operation and serious underlying diseases constitute the major risk factors of nosocomial infections in elderly patients. Prevention and control measures should be taken in a targeted manner.
