Objective To explore the influence of two emergency reception and triages workflows between Wenchuan and Lushan earthquakes on the victim’s length of stay in emergency department of the West China Hospital of Sichuan University. Methods A total of 65 victims admitted in the West China Hospital within 12 hours after Lushan earthquake were retrospectively analyzed, and their diagnosis and treatment information and the length of stay in emergency department were collected and compared with those of the victims in Wenchuan earthquake. Then we analyzed the influence of two emergency reception and triage workflows on the length of stay of the batches of earthquake victims. Results For the Lushan earthquake victims, the median length of stay in the emergency reception and triage workflow was 0.51 hour, while that was 2.13 hours for the Wenchuan earthquake victims, with a significant difference (Plt;0.05). Conclusion The emergency reception and triage workflow for Lushan earthquake victims is a summarized experience and improvement based on that for Wenchuan earthquake, which can be used as references for treating batches of victims in the emergency department after a disaster.
