某医院住院军队离退休干部院内感染特点与危险因素分析

Analysis on nosocomial infection characteristics and risk factors of retired military cadres in a hospital

目的 了解某三甲医院军队离退休干部住院患者的院内感染情况及风险因素。方法 回顾性分析某三甲医院住院军队离退休干部院内感染发生率、感染部位,多因素logistic回归分析其危险因素。结果 该院2021年度共收治783例住院军队离退休干部,院内感染127例,院内感染率为16.22%。感染部位主要为下呼吸道、泌尿道和上呼吸道感染,其中双重感染率达到17.32%,多重感染率达到5.51%。logistic回归分析结果显示,住院时间≥15 d、脑血管疾病后遗症、恶性肿瘤、慢性肾功能不全、慢性贫血与有创诊疗操作是独立危险因素。结论 住院军队离退休干部院内感染以下呼吸道和泌尿道感染为主,住院时间≥15 d、有创诊疗操作等为独立危险因素,应采取针对性的防控措施降低其院内感染率。

Objective To investigate nosocomial infection of retired military cadres in a third-class hospital, so as to analyze the risk factors of nosocomial infection. Methods The incidence and site of nosocomial infection were analyzed retrospectively, and the risk factors were analyzed by multivariate logistic regression. Results In 2021, a total of 783 hospitalized military retired cadres were admitted to the hospital. Among which 127 cases of nosocomial infection occurred, with the nosocomial infection rate of 16.22%. The infection sites were mainly lower respiratory tract, urinary tract and upper respiratory tract, in which the double infection rate was 17.32% and the multiple infection rate was 5.51%. Logistic regression analysis showed that length of hospital stay ≥15 d, sequelae of cerebrovascular disease, malignant tumor, chronic renal insufficiency, chronic anemia and invasive treatment were independent risk factors. Conclusion The following respiratory tract and urinary tract infection are the main nosocomial infection of hospitalized military retired cadres. The length of hospitalization ≥15 d, invasive diagnosis and treatment operation were independent risk factors. Targeted prevention and control measures should be taken to reduce the nosocomial infection rate.
