某儿童医院住院患者医院感染现患率调查与分析

Investigation on the prevalence rate of hospital acquired infection among inpatients at a children’s hospital

目的了解儿童医院住院患者医院感染现患率及危险因素,为预防医院感染提供科学依据。方法采用横断面调查方法,连续5年对某儿童医院住院患者医院感染现患率进行调查与分析。结果该儿童医院2013-2017年住院患者医院感染现患率分别为4. 19%、4. 83%、4. 66%、2. 30%和3. 43%;感染患者居前3位科室依次是五官科、小儿内科和小儿外科,感染部位呼吸道和手术部位居多。2015-2017年连续3年医院感染患者病原学标本检出阳性率依次为32. 50%、56. 52%和66. 67%。Logistic回归分析显示,医院感染独立危险因素主要是年龄、动静脉插管及其他侵入性操作。结论连续5年医院感染现患率较低,多重耐药菌分离率较高,侵袭性操作感染发生风险较大。

Objective To explore the prevalence rate and risk factors of hospital acquired infection at a children’s hospital,to provide evidence to prevent hospital acquired infection.Methods The prevalence rate of hospital acquired infection was investigated and analyzed by cross-sectional survey for 5 years at a children’s hospital.Results The results demonstrated that the prevalence rate of hospital acquired infection of inpatients were 4.19%,4.83%,4.66%,2.30%and 3.43%from2013 to 2017,respectively.The first three departments were ophthalmology and otorhinolaryngology,pediatric internal medicine and pediatric surgery with patients of hospital acquired infection,and the highest rate of hospital acquired infection were respiratory tract and surgical site.The infection rate of the pathogen test of hospital acquired infection were 32.50%,56.52%and 66.67%from 2015 to 2017,respectively.The Logistic regression analysis showed that age more than one year old,arteriovenous catheterization and invasive medical operation were independent risk factors for hospital acquired infection.Conclusions There was a lower prevalence rate of hospital acquired infection,the isolation rate of multiple resistance was high,and there was a greater risk with invasive medical operation of hospital acquired infection in the hospital.
