某三级医院医院感染趋势分析

Analysis on trend of healthcare-associated infection in a tertiary hospital

目的了解某三级医院各临床科室医院感染控制现状及发展趋势,为制定医院感染防控措施提供依据。方法采用轨迹分析模型对该院各临床科室2010—2012年医院感染数据进行分析。结果根据各临床科室医院感染率发展趋势,分为3个亚组:第1组占科室总数的80.7%,此组科室医院感染率较低,呈下降的发展趋势(slope=-0.45),差异有统计学意义(P=0.04);第2亚组占科室总数的16.0%,医院感染率较第1亚组高,总体也呈下降趋势(slope=-0.17),但差异无统计学意义(P=0.71);第3亚组只含重症监护室(ICU),医院感染率远高于其他科室,发展趋势为先上升后下降。结论轨迹分析模型可以较好地对临床科室进行分组,方便了解全院各科室的医院感染发展趋势,针对不同组科室医院感染特点,采取防控措施。

Objective To investigate the status and development trend of healthcare-associated infection（HAI） ina tertiary hospital,and provide a basis for formulating prevention and control measures.Methods HAI data of clinical departments in a hospital from 2010 to 2012 were analyzed with trajectory model.Results All clinical departments were divided into three groups according to development trend of HAI rate The first group accounted for 80.7％ of total departments,HAI rate of this group was low,and showed a decreased trend（slope =-0.45）,the difference was significant （P=0.04）; the second group accounted for 16.0％,HAI rate was higher than the first group and also showed declined trend（slope =-0.17）,the difference was not significant （P =0.17） ; the third group only contained intensive care unit,HAI rate was far higher than other departments,and the development trend of HAI rate increased first and then declined.Conclusion Trajectory analysis model can be used to divide clinical departments into different groups,is convenient to understand the development trend of HAI of every hospital department,and take measures to control HAI according to the characteristics of HAI of different clinical departments.
