Among practitioners of emergency medicine, the first hour after trauma is most critical. Treatment within 60 minutes of severe injury is often the difference between life and death. Nowhere is that fact more starkly evident than on the battlefield, report researchers at Texas A&M University, who say a military mandate in 2009 to get wounded personnel treatment in the first hour has resulted in thousands of saved lives.
The study analyzed battlefield data for more than 21,000 military casualties during U.S. involvement in Afghanistan between September 11, 2001 to March 31, 2014, comparing outcomes before and after the June 15, 2009 mandate.
Before the mandate, median time to transport a wounded service member was 90 minutes; after, it dropped to 43 minutes. Cutting median transport time in half also cut the fatality rate nearly as much, from 13.7 to 7.6 percent.
