The Pan-American Trauma Society (PTS) developed a Trauma and Emergency Ultrasound Course (USET) in response to the requirement for trauma ultrasound training for low- and middle-income countries. The objective of this study was to evaluate the efficiency of this course.

Pre- and post-course tests were used. An interval estimation of proportions was calculated at 95% CI. Theoretical and practical pre- and post-course knowledge were assessed with the Wilcoxon Signed Rank test at a 0.05 level of statistical significance.

Between 2005 and 2007, 114 students, including general surgeons, emergency medicine physicians, anesthesiologists, critical care physicians, and residents of these specialties, were trained in seven countries (Uruguay, Peru, Mexico, Venezuela, Aruba, Colombia, and Ecuador). The difference on complete knowledge ranked scores before and after the course was statistically significant (p <0.001). After the course, almost all participants (97.4%) demonstrated complete knowledge in final evaluation.

The USET course is an effective approach for trauma ultrasound training. Specific training programs for trauma care providers that work in low- and middle-income countries are necessary and could be performed with low-cost training programs.
