Lenz, A., Shelton, R., Ryznar, R., et al. (2020). The Next Nine Minutes: Lessons Learned from the Large-Scale Active Shooter Training Prior to the STEM School Shooting. (Abstract only.) American Journal of Disaster Medicine. 15(4): 241-249.
"The Next Nine Minutes,” a large active shooter drill, involved 904 personnel and 126 “patients” who wore “Cut Suits.” Those patients received 479 procedures (e.g., wound packs, needle decompressions, and tourniquets). Law enforcement established a “warm zone” and emergency medical services was able to extract and transport the first patient within 12 minutes. The lessons learned during this exercise were incorporated into several real-world responses, emphasizing the benefit of “in situ immersion training.”
