Hu, H., He, Y., Zhang, S., and Cao, Y. (2014). Streamlined Focused Assessment with Sonography for Mass Casualty Prehospital Triage of Blunt Torso Trauma Patients. (First page only.) American Journal of Emergency Medicine. 32(7):803-6.
The authors used a streamlined version of Focused Assessment with Sonography for Trauma (sFAST) to perform field triage of injured patients for the first 24 hours after a large earthquake. They compared their results to those obtained using the START algorithm, and determined that ultrasound yielded significantly more predictive information in a similar period of time.
