A comparison of four methods of testing emergency medical technician triage skills

Triage skills are requisite for all providers of prehospital care. Methods of assessing the acquisition of triage skills vary in complexity and expense. In this study, 61 prehospital care providers classified 20 cases, divided into four groups of five cases each: moulaged live trauma victims, nonmoulaged live trauma victims, nonmoulaged manikin trauma victims, and written scenarios. The providers were asked to classify the cases in each group by assigning triage tags to indicate injury severity and to rank the trauma victims in each group according to the urgency of care required. Analysis of variance revealed statistically significant differences among the four methods in both mean tagging scores (F3,235 = 8.63, P less than .0001) and mean ranking scores (F3,232 = 6.09, P less than .001). Multiple comparisons using Scheffe's test revealed that the mean tagging and ranking scores for moulaged live victims and written scenario methods were comparable and that both were significantly superior to the scores of the two other methods. However, a qualitative evaluation revealed that the providers greatly preferred triage of moulaged live victims to the other three methods.
