老年住院患者院内感染及影响因素分析

目的 探讨老年患者院内感染的发生率和影响因素。方法 以出院患者病历为依据,采用回顾性调查,比较2004年1月1日~2005年12月31日60岁~出院患者院内感染率及相关因素。结果 4 865例60岁~老年患者院内感染率为8.79%。不同年龄组院内感染率差异有统计学意义(P<0.01),随年龄增长,院内感染率增高;不同住院天数的院内感染率差异有统计学意义(P<0.01),随住院天数延长,院内感染率增高;院内感染发生部位以呼吸道(40.65%)和泌尿道(20.09%)为主。原发病为恶性肿瘤、糖尿病、慢性阻塞性肺病的院内感染率较高,分别为14.29%,13.31%和12.80%。院内感染病原菌以革兰阴性杆菌为主,占62.75%。结论 老年人住院期间易发生院内感染,感染发生与患者基础疾病、年龄、住院时间及侵入性操作等有关。应针对老年患者特点,制定综合预防措施,有效控制和降低老年患者院内感染率。

Investigation and analysis on nosocomial infection status of elder inpatient

Objective To investigate nosocomial infection of elder patients and other correlated factors.Methods Nosocomial infection rate and related factors were analyzed retrospectivly based on 4865 elder inpatients(≥60y)'s medical records from 1/1/2004 to 12/31/2005.Results Nosocomial infection rate of elder inpat ients over 60 years was 8.79%.There existed significant increasing trend of nosocomial infection rate with increasing of age and the day being in hospital,the older the age,the higher was the rate of nosocomial infection.And the longer the day being in hospital,the higher was the rate of nosocomial infection.Nosocomial infections occurred mainly in the respiratory tract(40.65%)and urinary tract(20.09%).The main pathogenic organisms of nosocomial infection were gram negative bacilli(62.75%).Conclusion Elder inpatients were easy getting nosocomial infections.Nosocomial infections were closely related to age,invasive operation,basal disease,the hospitalization period,etc.Prevention and proper treatment of nosocomial infection should be streng thened.
