2013—2015年某综合性医院医院感染现患率调查

［摘要］目的了解2013—2015年某院医院感染（HAI）现患情况,为提高HAI管理水平提供参考依据。方法采用横断面调查方法,对2013—2015年郑州大学第一附属医院住院患者进行HAI现患率调查,分析不同性别、不同年龄组的HAI现患率,以及HAI部位构成情况。结果2013—2015年应查29 605例,实查29 581例,实查率99.92%。2013—2015年HAI现患率分别为2.83%、2.14%、1.73%,三年间HAI现患率比较,差异有统计学意义（χ2=27.521,P<0.01）,呈逐年下降趋势。不同性别住院患者HAI现患率比较,男性HAI现患率为2.47%,高于女性HAI现患率1.98%,差异有统计学意义（χ2=7.954,P<0.01）。2013—2015年不同年龄组住院患者HAI现患率在年龄维度上大致呈“U”型分布,HAI现患率较高的为70~组（4.15%）,0~30岁年龄组HAI现患率随年龄的增加而降低,30岁年龄组之后HAI现患率随年龄的增加而升高。HAI部位构成居前3位的为下呼吸道（45.67%）、上呼吸道（9.92%）和泌尿道（8.52%）。结论该院现患率调查结果显示HAI现患率逐年降低,说明HAI防控措施落实有效。

Prevalence rates of healthcare associated infection at a general hospital in 2013-2015

ObjectiveTo investigate the prevalence of healthcare associated infection (HAI) in a hospital in 2013-2015, and provide reference for the improvement of HAI management. MethodsPrevalence rates of HAI among patients in the First Affiliated Hospital of Zhengzhou University in 2013-2015 were investigated with cross sectional survey method, prevalence rates of HAI and constituent ratios of HAI sites in patients of different genders and different age groups were analyzed. ResultsIn 2013-2015, 29 605 patients should be investigated, 29 581(99.92%) were actually investigated. Prevalence rates of HAI in 2013-2015 were 2.83%,2.14%,and 1.73%,respectively, difference was significant(χ2=27.521,P<0.01）, which showed a downward trend year by year. Prevalence rates of HAI in male was significantly higher than that of female (2.47% vs 1.98%, χ2=7.954, P<0.01). The prevalence rates of HAI in the age dimension was roughly U shaped distribution in 2013-2015. Prevalence rates of HAI in ≥70 age group was the highest( 4.15%), in 0-30 age group decreased with age, in > 30 age group increased with age. The top three sites for prevalence of HAI were lower respiratory tract (45.67%), upper respiratory tract (9.92%), and urinary tract (8.52%). ConclusionThe prevalence rates of HAI decreased year by year in 2013-2015, which suggests that HAI prevention and control measures are effectively implemented.
