ObjectiveTo investigate the correlation between rapid emergency medicine score (REMS) and therapeutic intervention scoring system (TISS-28) score and analyze the feasibility of assessing the nursing workload by REMS score for critically wounded earthquake victims, in order to provide reference for rapid and effective resource allocation for earthquake victims. MethodsA retrospective analysis was carried out on 39 Lushan earthquake victims with their acute plysiology and chronic health evaluationⅡ scores higher than 25, who were directly transferred from the earthquake site to the Emergency Department of West China Hospital between April 20 and 27, 2013. Among them, there were 24 males and 15 females aged between 5 and 90 years old averaging (57.1±19.8) years. REMS score and TISS-28 score were calculated for each victim. The relationship between REMS score and TISS-28 score was analyzed by correlation analysis and curve estimation including linear model, quadratic model, composite model, growth model, logarithm model, cubic model and exponential model. Then, we tried to find out the most suitable description for the relationship between REMS score and TISS-28 score. ResultsThe Spearman correlation coefficient between the two score systems was 0.710 and the most suitable description for the relationship between REMS score and TISS-28 score was logarithmic curve model. The formula was TISS=-5.946+4.467lnREMS. ConclusionREMS score can be applied as a nursing workload predicting tool for critically wounded victims in Lushan earthquake and it provides a guidance for rational allocation of health resources.
