目的:通过观察平均住院日数和医院感染发生率的数据,统计分析平均住院日对医院感染发生率的影响。方法:统计我院(三级甲等综合医院)2008年-2013年全院平均住院日和医院感染发生率,并进行相关性研究。结果:6年间,平均住院日从2008年的14.97天降至2013年的11.15天,医院感染发生率从2008年的3.99%降至2013年的1.67%,两者存在正相关关系。结论:随着平均住院日的逐渐缩短,医院感染发生率不断降低。
OBJECTIVE: To observe the effect of average length of stay on the incidence of nosocomial infections by observing the average number of hospital stays and the incidence of nosocomial infections. Methods: The average length of hospital stay and the incidence of nosocomial infection in our hospital (Grade A first-class general hospital) from 2008 to 2013 were statistically analyzed. Results: In 6 years, the average length of stay decreased from 14.97 days in 2008 to 11.15 days in 2013, and the incidence of nosocomial infections decreased from 3.99% in 2008 to 1.67% in 2013. There was a positive correlation between them. Conclusion: With the average length of stay reduced, the incidence of nosocomial infections has been declining.
