Trends in mortality of emergency departments patients in China / 世界急诊医学杂志（英文）

ABSTRACT

BACKGROUND@#Emergency medical service system (EMSS) in China is becoming more important. However, studies on mortality of emergency departments (EDs) patients in tertiary hospitals and on the trends in mortality of ED patients all over China are stagnant. The objective of this study was to quantify and describe the trends in mortality of ED patients in China.@*METHODS@#Nine tertiary teaching hospitals were selected from tertiary teaching hospitals in different regions. The annual numbers of ED visits and deaths of these hospitals in 2004, 2009 and 2014 were recorded and analyzed. Chi-square test was used to compare the mortality of the EDs' visits. Moreover, data on the mortality of ED patients in China from 2005 to 2015 were summarized and analyzed from the China Health and Family Planning Statistical Yearbooks (2006–2016).@*RESULTS@#From 2004 to 2014, the overall annual mortalities in EDs increased among the tertiary hospitals (P<0.001). However, the overall annual mortality in EDs all over China decreased from 0.12% in 2005 to 0.08% in 2015. And the mortalities of EDs patients in the eastern, central and western regions of China all decreased. In addition, the average mortality of EDs patients in northern China was obviously higher than that in southern China (P<0.05).@*CONCLUSION@#The ED mortality was increased in tertiary hospitals while decreased all over China during the past decade, which may be partly caused by some critical challenges faced by China's EMSS, such as overcrowding and long length of stay in EDs of tertiary hospitals.
