目的:探索呼吸内科老年患者院内感染的因素分析与预防措施。方法:选择2013年6月~2015年6月医院收治的100例呼吸内科老年患者为研究对象,采用回顾性调查法,分析研究对象院内感染因素,进而实施相应的预防措施。结果:下呼吸道感染率为35.00%,上呼吸道感染率为30.00%,泌尿生殖道感染率为10.00%,胃肠道感染率为7.00%,手术部位感染率为15.00%,其他感染率为3.00%。其中,下呼吸道和上呼吸道感染最常见;分析高危感染因素,年龄大、住院时间长、抗生素使用种类超过3种、有侵入性治疗、存在基础性疾病者易感染;分析病原菌种类,真菌感染占36.00%,铜绿假单胞菌占25.00%,肺炎克雷伯杆菌占8.00%,不动杆菌属占18.00%,大肠埃希菌占13.00%。其中,铜绿假单胞菌、真菌、不动杆菌属最常见。结论:在分析呼吸内科老年患者高危院内感染因素的基础上实施相应的预防措施,可有效降低院内感染发生率。
Objective: To explore the factors of nosocomial infection in elderly patients with respiratory medicine and preventive measures. Methods: A total of 100 elderly patients admitted to our hospital from June 2013 to June 2015 were enrolled in this study. Retrospective investigation was used to analyze the nosocomial infection factors in the study and to carry out corresponding preventive measures. Results: Lower respiratory tract infection rate was 35.00%, upper respiratory tract infection rate was 30.00%, genitourinary tract infection rate was 10.00%, gastrointestinal tract infection rate was 7.00%, surgical site infection rate was 15.00% and other infection rates were 3.00% . Among them, the lower respiratory tract and upper respiratory tract infection are the most common; analysis of risk factors for infection, older, longer hospital stay, more than 3 kinds of antibiotics used, invasive treatment, there is a basic disease susceptible; analysis of pathogenic bacteria, fungal infections 36.00%, Pseudomonas aeruginosa 25.00%, Klebsiella pneumoniae 8.00%, Acinetobacter 18.00% and Escherichia coli 13.00%. Among them, Pseudomonas aeruginosa, fungi, Acinetobacter are the most common. Conclusion: It is effective to reduce the incidence of nosocomial infection by implementing the corresponding preventive measures based on the analysis of high-risk nosocomial infections in elderly patients with respiratory medicine.
