Abstract

Purpose: The purpose of this study was to compare visual blood loss estimation and subjective emergency according to clothing color. Methods: This is a quasi-experimental study which involved the use of mock bleeding patients wearing different colors tops. Results: Differences in visual estimates according to clothing color were significant in both paramedic students (F=6.69, p=.002) and the general department students (F=20.92, p=.000). When looking specifically at the accuracy of visual estimates, the paramedic students group tended to underestimate (50% white, 62.5% black, 32.5% yellow) the actual blood volume in all experimental conditions. On the other hand, the general department group tended to overestimation (45% white, 40% black, 67.5% yellow). The subjective emergency was also found to differ between paramedic students (F=13.58, p=.000) and general department students (F=9.67, p=.000). Conclusion: Paramedics treating bleeding patients at pre-hospital stages need to pay attention to blood loss estimations depending on clothing color, a factor not to be neglected or underestimated.
