- W4297172960 abstract "In Brief Export BACKGROUND: Although the Stop the Bleed campaign’s impact is encouraging, gaps remain. These gaps include rapid skill decay, a lack of easy-to-use tourniquets for the untrained public, and training barriers that prevent scalability. A team of academic and industry partners developed the Layperson Audiovisual Assist Tourniquet (LAVA TQ)—the first audiovisual-enabled tourniquet for public use. LAVA TQ addresses known tourniquet application challenges and is novel in its design and technology. STUDY DESIGN: This study is a prospective, randomized, superiority trial comparing the ability of the untrained public to apply LAVA TQ to a simulated leg vs their ability to apply a Combat Application Tourniquet (CAT). The study team enrolled participants in Boston, MA; Frederick, MD; and Linköping, Sweden in 2022. The primary outcome was the proportion of successful applications of each tourniquet. Secondary outcomes included: mean time to application, placement position, reasons for failed application, and comfort with the devices. RESULTS: Participants applied the novel LAVA TQ successfully 93% (n = 66 of 71) of the time compared with 22% (n = 16 of 73) success applying CAT (relative risk 4.24 [95% CI 2.74 to 6.57]; p < 0.001). Participants applied LAVA TQ faster (74.1 seconds) than CAT (126 seconds ; p < 0.001) and experienced a greater gain in comfort using LAVA TQ than CAT. CONCLUSIONS: The untrained public is 4 times more likely to apply LAVA TQ correctly than CAT. The public also applies LAVA TQ faster than CAT and has more favorable opinions about its usability. LAVA TQ’s highly intuitive design and built-in audiovisual guidance solve known problems of layperson education and skill retention and could improve public bleeding control. In a multinational, randomized controlled trial, the untrained public is 4 times more likely to apply the novel Layperson Audiovisual Assist Tourniquet (LAVA TQ) correctly compared with a Combat Application Tourniquet (93% vs 22%). These findings suggest the intuitive LAVA TQ can help the public stop life-threatening hemorrhage." @default.
