心血管内科住院患者医院感染高危因素分析

Analysis of High Risk Factors of Nosocomial Infection in Patients With Cardiovascular Medicine

目的观察并探讨心血管内科住院患者医院感染高危因素。方法选取2016年10月—2017年10月我院收治的心血管内科住院患者280例,对所有患者临床资料进行回归性分析,并应用Logistics多因素分析患者医院感染的独立危险因素。结果所有患者中有47例患者发生医院感染,感染率为16.78%,其中下呼吸道感染及上呼吸道感染几率最高,分别为25.53%(12/47)、21.28%(10/47),住院天数多于14天、年龄大于70岁、有ICU住院史、住院期间外出检查、探视过多过频、意识障碍、慢性基础疾病以及手术是发生医院感染的主要因素。经过Logistics多因素分析得出,住院天数、年龄、手术、探视过多过频、慢性基础疾病是感染独立影响因素。结论心血管内科住院患者具有较高医院感染风险,医护人员需要加强对影响因素的全面认识,并针对影响因素及时采取有效防范措施,实现医院感染情况发生的几率。

Objective To observe and explore the risk factors of nosocomial infection in patients with cardiovascular medicine. Methods From October 2016 to October 2017, 280 hospitalized patients with cardiovascular medicine in our hospital were admitted. The clinical data of all patients were analyzed by regression analysis. The Logistics multiple factors were used to analyze the independent risk factors for patients with hospital infection. Results Nosocomial infection occurred in 47 patients. The infection rate was 16.78%, and the risk of lower respiratory tract infection and upper respiratory tract infection was the highest, 25.53% （12/47） and 21.28% （10/47） respectively. Hospitalization days are more than 14 days, age was more than 70 years old, there were ICU hospitalization history, out of hospital checkups, frequent visits, disturbance of consciousness, chronic underlying diseases and surgery is the main factor of nosocomial infection. After Logistics multi factor analysis, the number of hospitalization days, age, operation, overfrequency of overfrequency and chronic basic disease are the independent factors of infection. Conclusion Hospitalized patients in cardiovascular department have higher risk of nosocomial infection. Medical staf need to strengthen the overall understanding of the infuencing factors, and take efective preventive measures in time, so as to achieve the probability of nosocomial infection.
