Objective To study the value of SALT method in disaster assistance. Methods A total of 84 internship nurses from 2015 to 2017 were randomly divided into group SLAT and group START and accepted different classification methods training, then checked under the scene of simulated mass casualty events (car accident and earthquake) and the results of the examination were compared. Results The triage time of the SALT group was (8.00±1.36) min, (23.14±1.95) min,less than (10.05±1.34) min, (25.07±2.22) min in the START group in the car accident scene and the earthquake scene and the differences were statistically significant (t=-6.94,-4.23, P<0.05). The accuracy of different classifications under the same scene were compared and there was no statistical significance in the difference(P＞0.05). The accuracy of the triage in the car accident scene were better than earthquake scenes of the both SALT and START classifications and differences were statistically significant ( χ2=10.49, 10.54,P<0.05). The consistency of the SALT classification and the START classification was better (Kappa=0.526, P＜0.01). Conclusions The SALT method has the advantages of simple, easy to master, accurate and reliable. It is consistent with the traditional START method, but the time of classification is shorter and recommended to be used in the teaching of disaster medicine and the rescue of real disasters.
