近年来某军队医院及不同科室医院感染的趋势

目的调查近年来某军队医院总体医院感染率和重点科室医院感染率情况,并与过去进行比较,探讨其原因,为做好医院感染防控工作提供参考。方法通过终末病历调查某军队医院近3年(2011年1月1日-2013年12月31日)和前3年(2008年1月1日~2010年12月31日)医院感染率和各科室医院感染率情况,并对近3年和前3年数据进行统计学分析和比较。结果近3年医院感染率为4.05%(1319/32 547),前3年医院感染率为5.45%(1540/28 231),二者差异有统计学意义(P0.01);近3年来医院感染率高发科室依次为老干部科10.33%、神经外科9.82%和呼吸科7.05%,前3年分别为15.91%、13.79%和12.14%,近3年和前3年上述3个科室感染率比较差异均有统计学意义(P0.05)。结论近年来医院感染率呈下降趋势,医院感染高发科室依次为老干部科、神经外科和呼吸科,可能与这些科危重病人多,患者年龄大,住院时间长,免疫率低下等因素有关。

THE TREND OF HOSPITAL INFECTION IN A MILITARY HOSPITAL AND ITS DIFFERENT DEPARTMENTS IN RECENT YEARS

Objectives To investigate the recent hospital infection in a military hospital,and to compare that with previous data,so as to provide the basis for prevention and control of hospital infection. Methods The medical records of a military hospitl in recent 3 years（from Jan 1st 2011 to Dec 31 st 2013） were investigated and compared with those in past 3 years（from Jan 1st 2007 to Dec 31 st 2010）. Results The general hospital infection rate was 4. 05%（1319 /32 547） in recent three years,5. 45%（1540 /28 231）in past three years（P〈0. 01）. Geriatric,Surgical neurology and Respiratory department were the top three with the higher infection rate in recent and past three years〔10. 33% vs 15. 91%,9. 82% vs 13. 79%,7. 05% vs 12. 14% respectively（P〈0. 05）〕. Conclusion In recent years,the hospital infection rate has been declined. Geriatric,Surgical neurology,and Respiratory department were the top three departments with higher infection rate;the reasons may be increased numbers of critical patients,elderly age of patients,long hospitalization time and decreased immunity.
