摘要
目的:探讨慢性病住院患者院内感染的发生率和影响因素.方法:以7种常见慢性病出院患者病历资料为依据,回顾性调查分析2006-01-01/2007-12-31出院患者2586例院内感染的发生情况.结果:2586例慢性病住院患者院内感染率为8.1%.院内感染率与患者的基础疾病、年龄、住院时间及接受侵入性操作有关.不同年龄患者院内感染的发病率差异有统计学意义(P＜0.01),随着年龄的增长,院内感染发生率也增高;院内感染的发病率与住院天数有关(P＜0.01),随着住院天数延长,院内感染发生率增高;院内感染部位以呼吸道和泌尿道为主,分别占42.3%和22.1%.菌群组成以革兰阴性杆菌为主,占62.8%.结论:慢性病患者住院期间易发生院内感染,感染发生与患者的基础疾病、年龄、住院时间及侵入性操作等有关.应针对患者的特点,制定综合预防措施,以有效控制和切实降低院内感染发生率.
Abstract
AIM:To investigate the nosocomial infection of in-patients with chronic diseases and correlated factors. METHODS: Medical records of 2586 in-patients with chronic diseases from January 1,2006 to December 31,2007 were included in the study and the data of nosocomial infection were analyzed retrospectively. RESULTS: The nosocomial infection rate of in-patients with chronic disease was 8.1% and the nosocomial infection rate was related to the patients' underlying diseases,age,length of hospital stay and invasive treatment. The nosocomial infection rate increased significantly with the increase of age and the length of hospital stay ( P < 0. 01 ). Nosocomial infections occurred mainly in the respiratory tract (42. 3% ) and the urinary tract (22.1% ),and the main pathogenic organism of nosocomial infection was gram negative bacilli(62. 8% ). CONCLUSION: In-patients with chronic diseases are vulnerable to nosocomial infe ctions,which are closely related to the age,invasive treatment,underlying diseases and length of hospital stay. Prevention and proper treatment of nosocomial infection should be strengthened.
