目的:分析医院感染的发生情况,以便采取针对性措施,有效预防与控制医院感染。方法 :对2012年在我院发生医院感染的382例患者的临床资料进行回顾性调查。结果 :不同患者年龄、住院时间、原发疾病、侵入性操作等的医院感染发生率不同,年龄60岁以上人群占58.64%,住院7～30天占51.31%,颅脑疾病占19.64%,接受侵入性操作占66.23%。感染部位以呼吸道占首位,占70.68%。检出病原菌407株,主要为条件致病菌,以革兰氏阴性杆菌为主,占61.18%。结论:年龄大、住院时间较长(7～30天)、原发疾病重、接受侵入性操作的患者发生医院感染的可能性更大,重点关注以下人群,采取积极的预防与控制措施,可有效预防医院感染的发生。
Objective: To analyze the occurrence of nosocomial infections so that targeted measures can be taken to effectively prevent and control nosocomial infections. Methods: A retrospective study was conducted on the clinical data of 382 patients who developed nosocomial infection in our hospital in 2012. Results: The incidence of nosocomial infection was different among different patients’ age, length of hospital stay, primary disease, and invasive operation. The age of people over 60 years old accounted for 58.64%, the hospitalization for 7-30 days accounted for 51.31%, and the brain disease accounted for 19.64%. Invasive operations accounted for 66.23%. Respiratory tract occupied the most important site of infection, accounting for 70.68%. 407 strains of pathogenic bacteria were detected, mainly pathogenic bacteria, mainly gram-negative bacilli, accounting for 61.18%. Conclusions: Patients with older age, longer hospital stay (7-30 days), severe primary disease, and invasive procedures are more likely to develop nosocomial infections. They focus on the following groups and take active prevention and control measures. Effectively prevent the occurrence of nosocomial infections.
