目的研究不同ICU医院感染的特点,制定相应的预防控制措施,降低医院感染率。方法使用SPSS17.0和SAS 9.1对不同ICU医院感染率和感染部位构成进行描述性分析,采用ALOS调整法矫正患者病情的严重程度。结果 2010年1月-2012年6月共16 006例入住ICU≥48h的患者,总住院15 4597d,发生医院感染1653例、2816例次,感染率为10.45%、例次感染率为17.59%、日感染率10.69‰、日例次感染率为18.22‰;感染部位以呼吸系统感染最高,占47.41%,其次为血液系统和泌尿系统;不同ICU医院感染常见部位构成,差异有统计学意义(P<0.01)。结论不同ICU医院感染率、感染部位、器械相关感染率不同,有助于感染专职人员制定不同的预防和控制措施,尤其对经验性和预防性用药提供指导。
Objective To study the characteristics of different ICU nosocomial infections and to develop corresponding preventive and control measures to reduce the nosocomial infection rate. Methods SPSS 17.0 and SAS 9.1 were used to analyze the hospital infection rate and infection site composition in different ICUs. The severity of the patients’ condition was corrected by ALOS adjustment method. Results From January 2010 to June 2012, a total of 16 006 patients admitted to ICU≥48h were enrolled in this study. The total hospital stay was 15 4597 days. There were 1653 cases and 2816 cases of hospital infection, the infection rate was 10.45%, and the infection rate was 17.59% The daily infection rate was 10.69 ‰, and the daily infection rate was 18.22 ‰. The infected area was the highest with infection of respiratory system, accounting for 47.41%, followed by the blood system and urinary system. The common parts of different ICU nosocomial infections were statistically significant (P <0.01). Conclusion Infection rate, infection site and device-related infection rate in different ICU hospitals are different. It is helpful for infectious professionals to formulate different prevention and control measures, especially to provide guidance for empirical and preventive medication.
