精神疾病患者医院感染调查

Prevalence of nosocomial infections in patients with mental illness

目的：研究精神疾病住院患者出现医院感染的状况，为降低医院感染率提供依据。方法选择2012年5月－2014年10月在医院治疗的精神疾病住院患者2100例，回顾性分析患者医院感染率、感染部位。结果2100例患者中有74例发生医院感染，感染率为3．52％，男性39例，感染率为3．31％，女性35例，感染率为3．80％，差异无统计学意义；上呼吸道感染39例占52．70％，胃肠道感染8例占10．81％；住院＜100 d感染率为3．10％，住院101～190 d感染率为3．83％，住院＞191 d感染率为4．81％，差异有统计学意义（ P＜0．05）。结论住院精神疾病患者易发生医院感染，感染部位以上呼吸道和胃肠道为主，患者住院天数越多感染率越高。

OBJECTIVE To investigate the prevalence of nosocomial infections in hospitalized patients with mental illness so as to reduce the incidence of nosocomial infections .METHODS A total of 2 100 patients with mental ill‐ness who were hospitalized for treatment from May 2012 to Oct 2014 were enrolled in the study .The incidence of nosocomial infections and infection sites were retrospectively analyzed .RESULTS Of 2 100 patients ,74 had noso‐comial infections with the infection rate of 3 .52% ,including 39 male patients with the infection rate of 3 .31% and 35 female patients with the infection rate of 3 .80% ,and there was no significant difference .39 patients had upper respiratory tract infections ,accounting for 52 .70% ,and 8 patients had gastrointestinal tract infections ,account‐ing for 10 .81% .The infection rate was 3 .10% in the patients with the length of hospital stay varying from 0 to 100 days ,3 .83% in the patients with the length of hospital stay varying from 101 to 190 days ,4 .81% in the pa‐tients with the length of hospital stay more than 191 days ,and there was significant difference （P〈 0 .05） . CONCLUSION The hospitalized patients with mental illness are prone to have nosocomial infections ;the upper re‐spiratory tract and gastrointestinal tract are the major infection sites .The longer the length of hospital stay ,the higher the infection rate is .
