目的探讨心血管内科住院患者医院感染的相关因素。方法心血管内科住院患者合并医院感染共90例作为观察组;按照1∶1比例选择90例同期心血管内科住院患者无合并医院感染患者作为对照组,比较两组患者多种指标上的差异,进行多因素分析。结果单因素χ2t、检验12个变量是医院感染的危险因素(P<0.05),多因素回归分析,筛选出有实际意义影响医院感染的因素为:年龄超过60岁、实施侵入性操作、心功能Ⅲ~Ⅳ级、预防性抗生素,其OR值分别为3.38、2.86、2.23、2.01。结论心血管内科患者医院感染较高,影响因素较多,应针对上述因素采取相关预防措施。
Objective To investigate the related factors of nosocomial infection in cardiovascular patients. Methods A total of 90 hospitalized patients with cardiovascular inpatients were selected as the observation group. According to the ratio of 1: 1, 90 hospitalized patients with concurrent hospitalization without cardiovascular complications were selected as the control group. The differences between the two groups were compared. Multivariate analysis. Results The single factor χ2t, 12 variables tested were risk factors of nosocomial infection (P <0.05) .Multiple factor regression analysis showed that the influencing factors of nosocomial infection were: age over 60, invasive procedure, cardiac function Ⅲ ~ Ⅳ grade, preventive antibiotics, the OR values were 3.38,2.86,2.23,2.01. Conclusions Cardiovascular hospital patients have higher nosocomial infection and more influential factors. Relevant preventive measures should be taken according to the above factors.
