ObjectiveTo evaluate four triage methods including START, Care-Flight, rapid emergency medicinescore (REMS) and Sacco score for the length of hospital stay, length of ICU stay and the severity of injury in Lushan earthquake victims.MethodsA retrospective analysis was performed in 41 cases of critical earthquake victims in the emergency department of West China Hospital from April 20th to April 26th, 2013 in Lushan earthquake. The length of hospital stay and length of ICU stay were compared for four triage methods. The correlation between four triage methods and length of hospital stay, length of ICU stay and injury severity score (ISS) were also analyzed.ResultsThe length of ICU stay for victims whose triage level were red by START triage method or Care-Flight triage method was longer than whose triage levels were yellow. But the length of hospital stay for victims between the two triage levels had no significant difference. In addition, there was a correlation between critical victims and the length of ICU stay in the classification of START triage method and Care-Flight triage method.ConclusionThe length of ICU stay of the victims, whose triage level are red by START triage or Care-Flight triage methods, are longer than whose triage level are yellow. The levels of START and Care-Flight triage are correlated to length of ICU stay.
