目的 了解内、外科住院患者下呼吸道感染率不同的原因。方法 单因素χ2 检验和Logistic回归分析危险因素,并比较内、外科患者危险因素的差别。结果 经Logistic 回归分析内、外科均有10 个危险因素与呼吸道感染有关,内科患者中下呼吸道感染危险因素出现率为51.2% ,显著高于外科49.4% 。在众多危险因素中,内科患者中患慢性消耗疾病的比例显著高于外科,是造成两科室下呼吸道感染率差别的重要因素之一。结论 内科下呼吸道感染率显著高于外科的主要原因是危险因素出现率较高以及年龄构成所造成。
Objective To understand the reasons for the different rates of lower respiratory tract infections among inpatients in surgery and in surgery. Methods The single factor χ2 test and Logistic regression analysis of risk factors, and compare the difference between the risk factors in surgical patients. Results Logistic regression analysis showed that 10 risk factors were related to respiratory infection in internal and external surgery. The incidence of lower respiratory tract infection in medical patients was 51.2%, significantly higher than that of surgical patients (49.4%). Among the many risk factors, the proportion of chronic diseases consumed by medical patients is significantly higher than that of surgery, which is one of the important factors that cause the difference of lower respiratory tract infection rate between two departments. Conclusions The main reason why the lower respiratory tract infection rate of internal medicine is significantly higher than that of surgery is the high incidence of risk factors and the age composition.
